This article illustrated the impact of synthesized micro-structured spinel-type polycrystalline ferrites. The technique of conventional double sintering is used 〖MgFe〗_2 0_4, 〖Mg〗_0.5 〖Zn〗_0.5 〖Fe〗_2 O_4,〖Mg〗_0.35 〖Cu〗_0.20 〖Zn〗_0.45 〖Fe〗_2 O_4 and 〖Mg〗_0.35 〖Cu〗_0.20 〖Zn〗_0.45 〖Mn〗_0.06 〖Fe〗_1.94 O_4 to investigate their impact on the size of the grain, magnetic properties and the effect of divalent substitutions. Impurity phases aren’t detectable in the taken cubic spinel of single phases in the X-ray diffraction patterns. In the sample investigation it was observed that the density was tensed to increase, while the porosity decreased with the replacement of divalent ions. Microstructures show that there is an increase in grain growth as the addition of CuO is attributed to the liquid process due to CuO during sintering. At room temperature, all the samples exhibit a nice homogeneity for the sharp deterioration of  in T. Lower coercivity is found in all samples suggesting that the compounds are a type of soft ferrite magnets.

This study aims to evaluate the performance of the biogas plant to process cow dung in small-scale farms in rural areas. This biogas plant uses a digester from a 3,000-liter polyethylene tank equipped with a concrete inlet and outlet tub. The tank is planted into the ground upside down and connected to the inlet and outlet tub using 4 '' PVC pipes, as well as the gas line to the stove with a plastic hose, while the stove uses a modified LPG stove. The results of the digester performance test showed that the biogas production rate ranged from 96-104 liters/hour so that 1,244 liters of biogas were accumulated in the morning, 576 liters in the afternoon, and 589 liters in the afternoon. The total gas accumulated in the digester provides pressure between 150-220 mmH2O and is enough to push biogas from the digester to the stove. The use of biogas can turn on 2 ignition stoves at once in the morning for 230 minutes, afternoon for 112 minutes, and evening for 116 minutes. Environmental conditions in the digester with a pH of 7.5 and a constant temperature of 25 ºC can support the anaerobic fermentation process in the digester to produce an optimal and constant rate of biogas production. The residual fermentation slurry from the digester produced a total of 183 liters/day and contained 1.76% nitrogen, 0.81% P2O5, and 0.49% K2O.

For the RF analog applications, the two variants of FinFETs i.e., Independent gate (IG) and Short-circuited gate (SG) must be analyzed to understand the effect of different biases at the two gates. The variability of the device due to process variations fluctuates in accordance to the FinFET bias, at least for DC output. This paper provides a novel and systematic study of variability focusing on AC parameters in both SG and IG conditions for a 2-dimensional FinFET. Green's Function technique which uses the linearization of the non-linear responses is used to conduct the research utilizing a quasilinear state for the study of nonlinear variability [1], [2]. Study of FinFET's AC variability involves physical and geometric parameters which are most relevant for our analysis, as the parasitics of the FinFET are significantly affected by these parameters. The parasitics also varied with the two variants of the FinFET device.

Blank spots are still a problem in some areas in Indonesia so that in some areas internet data services are not covered. One solution to overcome this problem is by building a transceiver system using an Open Source Mobile Communication (OSMOCOM). However, this system has relatively low power with a narrow coverage area, so a multisite scheme is needed to cover a wider area. Therefore, in this study, an open source cellular network based on OSMOCOM was developed and implemented that can deliver mobile network with data services and supports multisite schemes. We designed this system as a second and half generation (2.5) of cellular communication technology. From the test results of the realized system, the multisite network can work synchronously where the Mobile Station has received data services at all realized sites. Mobile Station can access the internet with an average throughput of 52.8 Kbps and guaranteed package loss of not more than 10%. Handover mechanism can work properly where it can move the Mobile Station from the original cell to the neighboring cell and vice versa based on the power received criteria. In the future, the proposed system is expected to be applied in remote areas or areas which is not covered by cellular services.

This study aims to capture students' thinking error in the construction of mathematical proof, therefore this research is classified as a mixed methods. Student errors in mathematical proof are a reflection of her thinking. If these errors are not resolved, it will have an impact on students' thinking when working on further mathematical proof. This research was conducted on mathematics education students by asking students to complete proof of rational numbers. The results showed that the proof of thinking error occurs when students provide proof by providing a number or an example of a certain number. Actually students are able to do the proof that is given at the beginning of completing, but the resulting proof of the answer changes by entering numbers into the proof. The mistakes made by students are not only limited to corrections, but must be followed up by strengthening concept understanding and mastery of techniques and mathematical proof strategies.

Despite the burgeoning number of studies of e-government implementation, very few scholars have focused on the relationship between e-Government implementation success and the roles of actors' collaboration in particular within a local government context. Drawing on Van de Ven (2005) collective action theory, this paper endeavors to conduct an in-depth investigation through a case study of government actors perform collective action in local e-government implementation. Data were gathered through field observation, in-depth interviews, and written material. The data, then, were analyzed using the grounded theory approach through open, axial, and theoretical coding. By claiming that technology is fundamentally a collective action process, this study investigates the logic embedded in the actors' collaboration to build and implement e-Government at the local level. This study found that local government actors successfully perform a collective action in local e-government implementation through a harmony of coordination, cooperation, communication, and sharing responsibilities among local actors. Local e-government systems and infrastructures were built and implemented through intensive coordination and collaboration with the central government, internal local government, and private actors. Responsibilities to develop and maintain the local e-government systems and infrastructures are shared across local institutions.

This study aims to develop a conceptual procedure for the Problem Based Learning model by integrating flipped classrooms that are focused on conceptual development research based on Theory Driven type F1-O1-S1-A1. This study involved expert review in synthesizing the modified conceptual procedure model of PBL with FC. The observation sheet is used for the conceptualization analysis of the modification of the PBL model with FC which aims to obtain input and expert opinion on the subject matter developed through the application of the Delphi technique to improve mathematical argumentation skills. From the results of modifying the pbl model by integrating the flipped classroom, we get a new model called the Problem Based Learning-Flipped Classroom Model (PBL-FC Model). The PBL-FC model is designed in learning to enable students to construct meanings from spoken, written and graphic messages through interpreting, exemplifying, classifying, summarizing, concluding, comparing and explaining. Data analysis of argumentation skills was carried out using t-test. Based on the significance value of 0.000 ≤ 0.05 by using the t-test, there is an increase in mathematical argumentation skills in the application of the PBL-FC Model. This research recommendation is expected to be a theoretical basis for researchers and educators in measuring other skills.

Blackwater domestic waste is a type of wastewater that comes from human waste, so it needs proper treatment before being discharged into the river. So far, blackwater waste processing is carried out by storing it in a septic tank or directly channeling it to a sewage system to be processed in a domestic Wastewater Treatment Plant (IPAL). This study aims to increase the effectiveness of domestic wastewater treatment from communal IPAL using a physical model consisting of 2 processing processes, namely a stratified filter and a wetland. This study applied a stratified filter method consisting of gravel, activated charcoal and cast sand, then continued with a wetland system consisting of Vetiveria zizanioides (Vetiveria zizanioides) plants. The research variables observed were variations of wastewater discharge (X1), variations in thickness of sand (X2), wetland residence time (X3) at intervals of 2 days, 4 days and 6 days, and water quality parameters (Y) consisting of Fe. The data analysis method used is Linear Regression with the help of the SPSS program. The results showed that the use of a physical model consisting of multilevel filters and wetland was able to improve the quality of wastewater, where the output produced had met the quality standards of class IV agricultural water.

A failure at mining sites is a basic cause of death, serious injuries, economic and production losses. As open pit mines get larger and deeper with its related high risk of failure and consequences, slope monitoring methods become more important. Sub-surface methods and surface methods are common methods that have been applied to monitor stability of slope. Survey monitoring is technique of surface methods which include total station; global positioning system (GPS) and slope stability radar (SSR) are pointed as the most recent monitoring instruments in mining fields. Early detection of failure in mine slope can help implement appropriate monitoring technique and minimise failure effects. Slope monitoring in mining environment basically eliminates the residual risk associated with uncertainty in design and can play leading part of the final design implementation. Accurate monitoring program is a detailed plan of reporting procedures with a list of data collection by Geological engineer at early time, then processing and summarising the data to present it in simple format that is easy to read and identify problem area quickly.

Ambulu Village is a village located in Sumberasih District, Kab. Probolinggo. The majority of the population works as farmers and breeders. Some people in Ambulu Village cultivate catfish on a home industry scale and have not yet developed it professionally. UMKM "catfish PANTURA" is an initiation of proposers through community service programs. In 2018 the proposer carried out community service activities and focused on the main problem in "Pantura Catfish", namely diversification of processing and innovation in organic catfish cultivation. UMKM "catfish PANTURA" still has several problems, the first is the lack of power of women. Only men involved in cultivating marketing. The second problem is the increasing number of other village people who develop catfish cultivation so that the "PANTURA catfish" UMKM requires diversification of processed products to increase the selling price of catfish. The third problem is that marketing is still done manually by selling directly to middlemen or peddling around the Sumberasih sub-district. Seeing the problems and potentials of the catfish group "PANTURA", a women's cooperative called "PUTRI PANTURA" was initiated. Cooperatives are intended for mothers who have been unproductive. The concept of a cooperative that is formed is not only a savings and loan cooperative but also manages the management of cultivation, products, and marketing. To support the operation of women's cooperatives, product diversification training is also given to increase the selling value of organic catfish products. To facilitate cooperative management and product marketing, an e-cooperative system was designed. The e-cooperative system has collaborated with the E-Commerce system that has been developed previously.

Gilgit Baltistan (GB) Pakistan, is one of the most scenic parts of the world, which is blessed with unique natural resources. The major income of the people of the region is derived from tourism which is growing exponentially. However, no consistent and reliable data is available about the contributions of the tourism sector to the socioeconomic development of the area, both at local and national level. To address, this problem a research was initiated in the Hunza-Negar districts of GB. The standard Tourism Satellite Accounting (TSA) procedure and Tables were used for the purpose. A questionnaire survey was used to collect data for various inputs to the TSA. The respondents included inbound tourists, domestic tourists, day tripper, hotels and restaurants, passengers Transport Service providers, retailers etc. A total of 428 questionnaires were filled from various segments of respondents randomly selected from various cluster, and the response rate was 78.96%. The study was unique in its nature both at the regional and national levels. The study revealed that, there is high leakage of the revenue from tourism and hence the trickle down effects of the tourism sector is minimal. Huge investment has been made in last two decades in the construction of concrete structures with no regulation from building control authorities, leading to high unsustainable built environment in the region. The heavy influx of tourists and subsequent construction of new hotels and restaurants, has created heavy pressure on the land and trend of rapid urbanization. The local productivity has not been linked with the tourism sector and hence the socioeconomic development of the region is not happening in line with the expansion of the tourism sector. Based on the findings and observations of the study, policy recommendations have been made to the provincial and federal governments.

This paper identifies risk factors and how these risks are perceived in the construction industry within conflict zones, where risks are inherently greater and different. This involves identifying risk variables and aspects that affect how stakeholders shape their perceptions and make informed decisions. The research began by examining stakeholders in the construction industry within conflict zones, using the case study of Palestine. A qualitative research was adopted to gain a better understanding of the situation, using two sets of semi-structured stakeholders interviews and a review of policy documentation. The interview findings were transcribed, translated and analysed. A range of risk variables was uncovered, including movement restrictions, limitations in the locations of construction and problems related to particular policies. The findings also confirmed the applicability of different theories and revealed other aspects that affect risk perception, particularly: cultural, social and psychometric, as well as the process of policy implementation and validation. The interviewees considered that inappropriate implementation of policies is the main cause of poor construction development, followed by restrictions in movement and poor land management. This implies that there are problems and a lack of understanding in dealing with risk perception in the construction industry within conflict zones.

Slope stability is one of the most important problems in geotechnical engineering because failure could cause catastrophic environmental and human disaster, in addition to large economical losses due to such failure. The simplest solution to handle with slope failures is to avoid the failed zones and choose safer locations to move the projects which are decided to be constructed nearby the failed slopes. The paper delineates the effects of geofoam on soft clayey slopes which contain weak layers. This emphasis is given to the slope geometry, loading, and geofoam material that are numerically simulated using the finite element technique. In addition, the proposed stabilizing system is employed, presented, and analyzed. The analysis of the embankment is performed by the limit equilibrium analysis program (Slide V6.003). The increase in the geofoam thickness from 0.0m to 1.0m resulted in a noticeable increase in the safety factor for loaded and unloaded slopes. On another hand, increase in geofoam thickness from 1.0m up to 4.0m in case of unloaded slope, the safety factor is still constant for about 2.10. A consistent increase in the safety factors is noticed as a result of increasing the geofoam thickness from 0.0m up to 4.0m. Moreover, there is a slight decrease in the safety factor for loaded slopes during different values of geofoam position from the road level. The main factors which affect the slopes stabilized with geofoam such as, geofoam width, thickness, and position of the geofoam from the road level are also presented and discussed.

Nowadays, human sentiment analysis is one of the biggest challenges for computing technology researchers. Intelligent methods are used to capture human facial expressions then these expressions are analyzed by means of emotions, feelings, thinking, and behavior. Actually, it relates to human nature that can be observed and analyzed by person to person in a real-world environment. In this paper, we have proposed human sentiments analyses associate with social networking apps. These social networking apps must be built smarter so that they could interact with human sentiments. One of the widely used social networking web apps is Facebook, people used to connect, share their achievements, feelings, thinking, point of views, observations, and most probably emotions, through upload status, pictures, videos, and many other ways. We can achieve the goal by collaborating both fields such as human psychology and cognitive, possible to implement while connecting the camera with deep learning computing technology. Detecting and recognizing the real-time face image, analyzing facial expressions, and recommend activities according to the experimental outcomes of the analysis. The purpose is to generate an intelligent bridge between humans and computers which interact in a smart manner.

Ransomware transformed into a form of criminal business. malware that takes over a victim's machine or data unusable. it is booming so fast all the world, it is a dangerous threat to users’ and corporates’ data file. Ransomware encrypts files on an infected computer and holds the key to decrypt the files until the victim pays a ransom (this is why it is called ransomware). Ransomware is causing losses financially from hundreds of millions of dollars annually. Every year passes we observe a new version of this destructive malware. And the new versions have new technologies to bypass the defenders. In this paper, we present a brief history of ransomware, the best methods to prevent the infection, how to detect it, and how to recover from this infection. This monster has estimated financial damage of $1 billion. The fact that many Internet users appear to have no awareness of ransomware and do how to awake and protect themselves, they think that with a highly automated tool like it they won’t be targeted because they are normal users in Cyberspace.

Despite its multicultural heritage, the United States is still grappling with the task to build an all-inclusive healthcare workforce that reflects its current demographic reality and carter for the health requirements of its progressively heterogeneous patient population. The nation’s colored people are still marginalized in numerous healthcare establishments. Diversity in the healthcare workforce is not just an instrument to make sure there is enough provision of humanly adept care to the nation’s flourishing minority population but can serve as a strategic blueprint to ease entry to health services for the underprivileged neighborhood and uplift the standard of care given to race-related minorities/groups. Hence, it has become very necessary to frankly address the anomalies of lack of access/inclusion and reap the benefits of our nation’s strength in diversity while solving the distinctive health/economic difficulties of the colored people. The fight to create a culture of equal access, inclusion and utility in the Healthcare sector should be a national project. Therefore, this paper aims to lead the discussion on making a case for an increase in the diversity of our workforce in the healthcare sector in America relying on the equity theory. In conclusion the movement there are more advantages/strengths than weaknesses in the diverseness and heterogeneity of our population. Therefore diverseness in the healthcare workforce is not just a tool to promote the provision of quality care to the nation’s flourishing minority population but can serve as a strategic policy to ease entry to health services for the underprivileged, reverse the long stretch of injustice against the colored people, and engender a just/prosperous society.

Mobile Social Network (MSN) is an emerging area in recent years where many users are enjoying the facilities of social network on their mobile devices. Encounter-based MSN is a type of MSN where users share a short encounter, exchange some encounter information, and communicate later with the help of the shared encounter information. Encounter-based MSN inherent most of the security and privacy issues associated with MSN. Profile matching is an important and vastly used application of MSN as well as encounter-based MSN. In profile matching, users need to share and match their private information (such as interests). A high similarity may lead to a friendship. The revelation of this private information to an attacker can pose significant threats to the user’s privacy. In encounter-based MSN, a significant issue is the secure and accurate exchange of encounter information that can be later used for verification of the encounter. This paper proposes a secure and privacy preserving profile matching mechanism for encounter-based MSN. We have proposed a secure encounter phase and a profile matching phase. During encounter phase, users share their identity along with their signed public key and encrypted interests. The public key is signed by a registration server. During the profile matching phase, users’ encrypted interests are matched, and the encrypted results are sent to respective users. The exchange of this information is in encrypted form and only legitimate user can decrypt it. To show the feasibility of the proposed scheme, the computational cost is calculated. In the end, it is observed that the proposed scheme is taking reasonable time to calculate the interests securely. Moreover, the comparison shows that proposed scheme also provides prevention from Sybil attacks, impersonation while keeping the privacy of the users intact. Index Terms— Encounter based mobile social network, Interests, Mobile social network (MSN), Privacy, Paillier cryptosystem, Profile matching, Security.

Corrosion behavior of ß-type titanium alloy, Ti-12Cr, has been investigated within artificial saliva solution to acquire its potential as orthodontic application. Solution treated alloy (Ti-12CrST), aging treated alloy (Ti-12CrAT 60 ks, Ti-12CrAT 30 ks), and CpTi, as a comparator for these two materials, have been immersed in solution at constant temperature 37°C and pH 5 to imitate human body condition. Corrosion behavior was carried out by applying weight loss method with different exposure times (1, 2 and 3 weeks). Surface morphology was analyzed by using scanning electron microscopy (SEM). Energy dispersive X-Ray (EDX) was used to determine thechemical compositions. The results reveal that the corrosion rate of Ti-12CrAT 60ks, Ti-12CrAT 30ks, Ti-12CrST, and Cp-Ti alloys are 3.88x10-6mmpy, 4.18x10-6mmpy, 4.50x10-6mmpy, and 7.70 x10-6mmpy, respectively. The corrosion rate of all Ti-12Cr types is lower than that of the Cp-Ti. The hardness of Ti-12Cr and Cp-Ti alloys decreased by the exposure time. Ti-12CrAT 30ks with 410.4 HVN has the highest hardness value while Cp-Ti with 158.8 HVN has the lowest one. Low oxygen content on the Ti-12CrAT 60ks surface indicates its corrosion resistance. It can be concluded that the best material for orthodontic application from the corrosion resistance view is Ti-12CrAT 60ks.

With the increasing protection of consumer rights, the system of right of return without reason has been regarded as an important methode of consumer protection by more and more countries. Due to the conflict with the principle of freedom of contract, the system of right of return without reason has always been disputed in the theoretical circles. Behavioral economics provides a new perspective for the theoretical study of the right of return without reason. It puts forward the bounded rationality theory on the basis of criticizing the basic assumption of the "Homo Economicus / Economic Man" in classical economics. The bounded rationality theory explains the conflict between the right of return without reason and the freedom of contract principle, and is also an important basis for the right of return without reason. The main research method in the article is the literature research method. Under the circumstance that current Indonesian law does not have right of return without reason, this article will provide a theoretical basis for the right of return without reason in Indonesian law system.

ICT literacy is essentially regarded as one of six strategies in the digital development plan for the Thai economy and society. The identification of students who are ICT literate and those that are not is therefore crucial. Educational institutions normally provide capability testing to classify ICT literacy of students; however, it is inconvenient to examine large groups by testing. This research proposed data mining techniques from historical student information for classification based on a decision tree, to build a model for the ICT literacy classification of the new students. In this way, the results of the ICT capabilities of students will be recognized with no need for knowledge examination by testing all students. If the result of prediction shows that students have low ICT literacy, they are required to attend an online course to improve their ICT literacy skills. As this research created a decision rule using the C4.5 algorithms and tested the predictive efficiency, the accuracy is 86.12%.

Typhoid fever is caused by Salmonella enteric subspecies 1 serotype typhi. It is difficult to diagnose properly typhoid fever because it involves many variables. Although many medicines are available for the cure of typhoid fever but still a high mortality rate is recorded due to typhoid fever. Many variables are involved in the analysis and documentation of this disease. It becomes more difficult by the uncertainty linked with these variables. If the diagnosis of a disease is accurate then the effectiveness of the treatment will be high, these complications require new advanced techniques and computer tools can be used to manage, store and to achieve the correct medical information which is required by the physicians. These tools suggest timely and accurate diagnosis, prognosis and beneficial decisions. Simulated brainpower is a component of Computer Science that makes computers quick and more efficient. Computer Aided Decision Support System (DSS) is more important as it provide assistance as a server to the physicians in the medical domain by simulating expert human reasoning. For a physician in the medical domain diagnosis, classification and treatment of the disease are the major tasks. In Artificial Intelligence (AI) research the development of system with these objectives is of more interest. More than one AI methods and technique are combined with developed clinical decision support system to complete such multipurpose tasks.

the objective of this study is to investigate the impact of training, compensation, and working environment on employee motivation. Survey research designed adopted in this study. To test the hypothesis of the study data was collected using random sampling techniques from 250 Bank Employees, in Rawalpindi. The independent variables were used including Compensation, Working Environment, and Training against Employee Motivation that served as the basis of the dependent variable. The data was run on SPSS to get the results. To find the importance of these variables and to evaluate the results Cronbach’s Alpha, descriptive statistics, correlation, regression, and ANOVA were used. The results show that the independent variables Compensation, Working Environment, and Training has a positive and significant relationship with the dependent variable Employees Motivation.

The main goal of this study is identifying the perceptions and experiences of Saudis with the adoption of internet banking services. While most of the available literature centers on the Western context, some studies have focused on an Eastern context. The research applied a qualitative design to investigate the phenomenon. Purposeful sampling was used to select 57 participants, among whom were 12 middle-level bank managers from IT and sales departments and 45 customers associated with three banks - Saudi British Bank (SABB), Riyadh Bank and Banque Saudi Fransi. Only 30 participants were available during the period that the research was conducted. They were interviewed and thematic analysis was used to analyze the textual data from the interview responses. The themes that arose were trust, privacy, complexity, and infrastructure. This study concludes that there is a need to train bank employees and enlighten the population on the benefits of internet banking.

Ghana has a stockpile of disused radioactive sources that need to be managed and dispose of. The Accra Plains is a probable site to host such a repository in Ghana. To evaluate the long-term safety of the proposed repository, a model of the geosphere and disposal system of a hypothetical radioactive waste repository sited in the Accra Plains, was developed using the AMBER simulation tool. After the engineered barriers of the repository deteriorate, undecayed radionuclides escape through groundwater and migrate through the geosphere. The model functions to monitor the escaping radionuclides, to mitigate its effects on humans and the environment. The model also purposes as a tool for calculation of the annual effective dose on a receptor dwelling around an abstraction borehole located at 4km, 1km and 200m down the hydraulic gradient of the hypothetical repository. Predicted results were used to assess the suitability of the site to host such a repository. Radiation exposure to the receptor is assumed to occur from abstraction and use of groundwater from the geosphere via the abstraction borehole. The groundwater is used for domestic purposes, that is drinking, and agricultural purposes, viz., watering animals and irrigation of crops. The predicted results for liquid releases in terms of the calculated peak annual effective dose in all cases were significantly lower than the International Commission on Radiological Protection (ICRP) dose constraint of 0.3mSv/y. The results thus indicate that the Accra Plains is capable to safely host a radioactive waste disposal facility for Ghana’s disused radioactive sources.
