The corresponding study was carried out to detect changes in audio file using spectrograph. An audio file format is a file format for storing digital audio data on a computer system. A sound spectrograph is a laboratory instrument that displays a graphical representation of the strengths of the various component frequencies of a sound as time passes. The objectives of the study were to find the changes in spectrograph of audio after altering them, to compare altering changes with spectrograph of original files and to check for similarity and difference in mp3 and wav. Five different alterations were carried out on each audio file to analyze the differences between the original and the altered file. For altering the audio file (MP3 or WAV) by cut/copy, the file was opened in Audacity. A different audio was then pasted to the audio file. This new file was analyzed to view the differences. By adjusting the necessary parameters, the noise was reduced. The differences between the new file and the original file were analyzed. By adjusting the parameters from the dialog box, the necessary changes were made. The edited audio file was opened in the software named spek where after analyzing a graph is obtained of that particular file which is saved for further analysis. The original audio graph received was combined with the edited audio file graph to see the alterations.

It is important to recognize that the design of any machine is an interdisciplinary process, involving aerodynamics, thermodynamics, fluid dynamics, stress analysis, vibration analysis, the selection of materials, and the requirements for manufacturing. The operation of any mechanical system will always produce some vibration. Our goal is to minimize the effect of these vibrations, because while it is undesirable, vibration is unavoidable. The result of excess vibration can vary from nuisance disturbance to a catastrophic failure. Bike chassis is a major component in a vehicle system. This work involves vibration analysis to determine the key characteristics of a bike chassis. The dynamic characteristics of bike chassis such as the natural frequency and mode shape were determined by using finite element (FE) method. Al material will replace the conventional MS material. Experimental modal analysis was carried out to validate the FE models. Predicted natural frequency and mode shape were validated against the experimental results. Finally, the modification of the updated FE bike chassis model was proposed to reduce the vibration, improve the strength and optimize the weight of the bike chassis. Tools used are catiaV5 for 3D modelling, Hypermesh for meshing, and Ansys for post processing.

In a world that undeniably competes for investment, visitors and residents, the adoption of approaches derived from the marketing has become a reality in the search for sustainability. It is a fact that a city marketing policy is able to promote and transform an image, boost economic activity and enhance all aspects of the city that present competitive advantage over other territories, so this is why associate marketing with cities makes sense. This study aims a better understanding of the city marketing problem and their relationship with the events, especially through the perceptions that residents have toward the events themselves, and how this may influence their attitudes. Although the cultural approach of the city has been evolving in order to be an effective vehicle for the development of cities, this often represents failure, due to lack of strategic policies. Being the Carnival of Ovar the largest event and the one that brings more benefits to the city, the primary purpose of this research was to analyze the influence of the residents’ perceptions in their attitudes, in particular the support for this event.

Emerging new Technologies and large scale businesses have made this world, a global village. Many business organizations provide online services targeting global consumer bases. Transaction in international scale has been enabled by banks all around the world through E-banking in order to supply the needs of above business organizations. E-banking serves lots of benefits to both customers of banks and banks itself. It adds value to customer’s satisfaction with better service quality and enables banks to gain a competitive advantage over other competitors. Online banking need to possess high level security in order to provide safe, consistent, and robust online environment which guarantees secure data transmission and identity of both bank and customer. Lack of security may lead to less trust or hard to trust attitude towards online banking. Although customers are attracted by online banking convenience, they seem largely in concern about identity theft and phishing. Analysis of many research papers on e-banking security models and their respective advantages and disadvantages have been discussed in literature review. Username, password, E-banking dongles, fractal images, biometric scans and advanced encryption standards are some of the suggested solutions for E-banking security. This study focuses on the security beyond above mechanisms. This paper ensures security of online banking at three levels. At client side, using internet dongle integrated with finger print scanning technology, at banking sever side and data transmission level. This model also includes username, password and advanced encryption for further security. Complete description on the model has been discussed in methodology section. Future works on this topic and Conclusion are covered in separate sections.

Nowadays the agenda of corruption eradication have been undertaken by various institutions such as the judiciary, the police, the Corruption Eradication Commission and other bodies related to the corruption eradication. The type of research used in this study is normative-jurisdiction and empirical-jurisdiction. To obtain the necessary data in this study, the researcher conducted library research as a reference in some libraries are quite representative. Results shows that the effectiveness of corruption eradication that conducted by regulatory authorities in order to combat corruption has not been implemented maximally, because each institution as a subsystem has not carried out an interdependent relationship both vertical and horizontal nature. If we expect the eradication of corruption can be implemented optimally, it is recommended that the coordination between law enforcement agencies in the integrated criminal justice system is necessary to build their common vision, interpretation and perception in the implementation of the duties for the institution authorized to eradicate corruption.

My aim is to discover moral and ethical sides of 3D printing which is a new technology and, paradoxically, a new phenomenon of the twenty-first century. Particularly, 3D bioprinted organs and tissues is a controversial issue, because this technological advancement may be viewed by society as a servant or it can even potentially become its master. For example, in the health care system, doctors may change their attitude to patients by using 3D bioprinted organs and tissues whenever it is needed, also, taking away responsibility from patients. Thus, there can be great social and psychological consequences from 3D bioprinting in a long term. Furthermore, Pete Basiliere, an analyst in a world's leading information technology research company, suggests that 3D printing can also bring economic consequences, resulting in the loss of at least $100 billion in intellectual property theft per year by 2018 globally. By analysing the economic, psychological and social impact of the 3D printing technologies, I want to research whether anyone is going be responsible for the 3D printing production and who is going to give a right to 3D bioprint.

Much effort has been dedicated to achieving realism in the simulation of deformable objects such as cloth, hair, rubber, sea water, smoke and human soft tissue in surgical simulation. However, the deformable object in these simulations will exhibit physically correct behaviors true to the behavior of real objects when any force is applied to it, and sometimes this requires real-time simulation. No matter how complex the geometry is, real-time simulation is still required in some applications. Surgery simulation is an example of the need for real-time simulation. This situation has attracted the attention of a wide community of researchers such as computer scientists, mechanical engineers, biomechanics and computational geometers. This paper presents a review of the existing techniques for modeling deformable objects which have been developed within the last three decades for different computer graphics interactive applications.

Geological and geotechnical study was conducted in concrete gravity dam which is planned to be constructed in the Maychew River 40 km south of Axum town for the purpose of water supply for the town. The objectives of this research were: to map geology of the area, to characterize geological defects within and around dam site, to evaluate the water tightness of the dam site, and to determine the bearing capacity of the dam foundation. The research involved: review of different literatures, lithological and structural mapping, characterizing rock masses by using different rock mass classification methods, interpretation of subsurface data (geophysical, core drilled data, test pit data etc.). Results of the study indicate that the area is underlain by Quaternary sediments, metasedimentary and metavolcanic rocks. The Quaternary sediments are characterized by low permeability, low plasticity and are poorly graded nature. Metasedimentary rocks are found covering the right abutment of the dam whereas at reservoir area it is found intercalating with metavolcanic rocks. These rocks are moderately jointed and sheared with faulting and folding noticed; due to these they have a relatively high permeability. Metavolcanic rocks which are found covering the left abutment are strong, less permeable and fractured. Most of discontinuities such as fractures, bedding and foliation in the study area are oriented E-W, NNW-SSE and NNE-SSW. The VES, tomography and drilled core result revealed that the potential problems (seepage/leakage) could occur due to presence of faults, joints, karstified black limestone, lithological variations, groundwater depth and topography at right abutment. Differential settlements may also occur because empirically estimated moduli of deformation (Ed) of rock masses indicate that for right abutment much less than left abutment and different geological defects across the dam axis. To minimize these problems contact grouting and consolidation grouting are recommended as mitigation measurements.

This study investigates the variability in yield, oxidative status and appearance of palm oils as affected by fruit type and extraction equipment in the small scale industry. A 2×3 factorial experimental design with palm fruit types (Dura and Tenera) and extraction equipment (digester screw, hand spindle and hydraulic presses) were studied. Quality indices of oils (i.e. free fatty acid (ffa), peroxide value, moisture content, impurities, colour) and yield were accessed using standard methods. The ffa values obtained for oils produced from both Dura and Tenera fruit types and the extraction equipment ranged 5.25% - 5.71%, were above the CODEX standard of 5.0 %. Furthermore, significant differences were also recorded in both moisture contents and impurities from the same oils produced. The oil yield from Tenera fruit types were two folds higher than the Dura fruit types. The redness colour of palm oils for Dura fruit types was a little above the Tenera fruit types. However, the yellowness and lightness of colour of palm oils for Tenera were higher than oils from Dura fruit types. Therefore the study concludes that the oil processors in the small scale industry preferred the digester screw press machine because it gave low level of impurities and moisture content than other presses. Tenera fruit type is the best choice for palm oil processing because of its higher oil yield content. However, in terms of oil colour Dura fruit type is preferred.

Recently, there has been common trend among people to refuse from food and medications produced via synthetic method, but try to consume natural products as much as possible instead. In this regard, wild berries and medicinal plants are considered to be highly essential for human health as these kinds of plants serve as rich sources of biological active substances-phenol compounds. As a result of conducting research on source and spread of herbs which are commonly used as anti-diabetic medication, we have developed a technological method to extract preparations from medicinal herbs such as Peony (Paeonia lactiflora Pall), Dandelion (Taraxacum officinalis Wigg.), Huckleberry (Vaccinium myrtillus L), Blueberry (Vaccinium uliginosum L), Cranberry (Vaccinium vitisidaea L), and Stinging nettles (Urtica dioica), accordingly studied chemical composition and antioxidant activity, and conducted pharmacological study. With the use of Folin Denis & Folin Ciocalteu reagent method,it was determined that the content of polyphenol compounds was 4.14-5.17% and 27.5 – 101.5mg/ml. The study was also aimed to investigate DPPH* free radical-scavenging activity in connection with term, temperature and concentration to identify the most rational technological procedure. As a result of study, it was identified that free radical-scavenging activity of herbs selected for the study was generally estimated at 564.25-1750.00 mcg/ml, whereas antioxidant activity of solvents with 2-10 mg/ml concentration was 417.20-1750.00 mcg /ml, respectively. This shows that such activity is dependent on concentration. However, in temperature of 30 – 1000С degrees, their activity has slowly been decreased by 1750 mcg/ml – 476.7mcg/ml depending on temperature. Regarding the stinging nettles, the activity was grown directly dependent from temperature. DPHH* free radical-scavenging activity was gradually increased in 1-10 minutes, but was relatively stable and active in 11-16 minutes.

The purpose of this study was to find out the performance of the selected fourth year high school day students in Carmen National High School Carmen, Cebu in fundamental operations with or without calculator. Calculators are great invention that in one way or another helped the children in doing some of their mathematical computations. But a desire to identify the current condition of the students in performing basic mathematical computations by comparing their computational ability without using calculators and of using calculators pushes these curious minds to pursue this study. This study was conducted during the School Year 2013-2014.In conducting the study, the description method was utilized with the help of a researcher-made questionnaire as the main tool in gathering data in order to come up with sufficient and justifiable results. There are 229 respondents out of 535 total populations of the day session fourth year high school students.The results showed that the students were performing well in doing calculations with the use of calculators compared to those who were not using calculators. It only confirmed their dependency on calculators in solving basic mathematical computations, which by any case, only traces its disadvantages to the teaching matters. Attitude like relying on inventions that gave direct, fast and accommodating features were observable in most students and always results to weakening ability to judge the correctness of an answer due to the fact that they do not think of the real concept enough to determine what type of answer to expect.

The design of buildings in public educational institutions in Ghana predominantly adopts open-plan offices that are naturally ventilated with the aid of operable windows for reasons such as achieving adaptable spaces, improved social climate and effective ventilation. However, adoption of open-plan naturally ventilated offices in these educational institutions expose occupants to noise that emanates indoors and from outdoor sources which can interfere with and impede work performance. The study aimed at assessing noise exposure levels and occupants' satisfaction with noise level in selected naturally ventilated open-plan offices in Ghana. The study employed an empirical assessment of the noise levels in and around three of the office buildings using a PCE222 Digital Sound Level Meter and a survey involving interviews to assess workers' satisfaction of noise levels of the open-plan offices at the Kwame Nkrumah University of Science and Technology in Kumasi. The results show that mean outdoor noise levels for offices ranged from 11 per cent below to 5 per cent above the WHO permissible limits, while mean indoor noise levels exceeded the limit by between 20-40 per cent during the course of the day. In spite of the high levels of noise, occupants generally considered the overall noise level in their offices as acceptable. Likewise, the results indicate that there are no significant differences in occupants' exposure to noise from their various sitting positions in an office space and floor levels in an office building. The paper recommends strategies to manage and improve ambient noise quality within naturally ventilated open-plan office spaces in Ghana. The study will be of relevance as a useful guide to organizations and policy makers concerned with built environmental issues.

Durio kutejensis the local durian forest result Kalimantan that has not been widely known outside of the island and not much cultivated. One of the obstacles of plant propagation is seedling superior quality are not available. Propagation through the technique of in vitro (Tissue culture) in plants Durio kutejensis (Hassk) & Becc not been widely tested, because the woody plants have grown a great degree of difficulty. Commonly cultivated plants through in vivo techniques. Sterilization is an important part of the culture in vitro. Sterilization of models have been tried, to overcome the initial barriers of culture. The development of in vitro embryo culture D. kutejensis through embryo explants using Murashige and Skoog (MS) with the addition of growth regulators GA3 (gibberellic acid) and BAP (Benzilaminopurine) produces elongation of hypocotyl added shoot growth and root elongation. Callus formed from embryonic explants green and yellowish white with compact texture on the addition of growth regulators BAP and 2.4 D 1gr/l. Callus formation has not been followed by the development of embryogenesis and not yet differentiation into shoots and roots.

Skill acquisition is a critical component of any vocational or technical training program. When this component is missing or falls below expectation, it tends to defeat the objectives or the essence of the program. In Nigeria, many skill acquisition institutions experience great challenges in trying to provide the necessary facilities required for effective vocational training of those enrolled in their programs because of paucity of funds. The result is that students graduate from the programs without adequate employability skills for meaningful productive/service work after leaving school. In realization of this shortfall, government has directed technical colleges to establish what is called Production/Service Work (PSW) into its curriculum. This is with the view that in the event that there is shortfall in the supply of training facilities by sponsors of the programs, jobs could be brought in from inside or outside the school which could provide opportunity for students to acquire hands-on experience that would equip them with requisite skills for post-graduation work. As laudable as this initiative appears to be many schools in the North Central Nigeria are yet to implement the directive of the federal government in their schools, and even where this has been done, its implementation does not appear to be viable. Over the years, different technical colleges have adopted different approaches toward the establishment and management of production/service work in their schools. While some have recorded appreciable success in its implementation, others seem to exist only in name. The present study, therefore, sought to identify the current practices employed in the use of PSW in technical colleges, the appropriateness of the practices in use, and the alternative practices that could be adopted to improve and guide the implementation of the program with a view to enhancing the acquisition of employability skills in technical colleges in North Central Nigeria.

The increase of competition in the local and regional markets is forcing companies to provide high quality products and services, as well as to continuously improve their activities. The quality management systems and standard implementation in Albanian companies are the at the focus of this paper with the intention to evidence the actual situation and the results achieved from the certification process. The implementation of ISO standard requirements, together with the assessment of the benefits deriving from it, is a relatively new experience for Albanian companies and slightly developed in our economic literature. Consequently, this work follows a combined approach of reviewing the relevant rich literature of the last decades with the empirical survey of some Albanian companies that have chosen ISO certification as an instrument to gain competitive advantage in the market. The analysis of factors that drive companies towards such time consuming, costly, and managerially- wise committed process, is one of main study’ objectives. It is followed by the assessment of benefits deriving from this process for companies in quantitative and qualitative terms. Comparing the expected advantages from the certification with those actually obtained might assist companies themselves to improve their processes. From the other side, this comparison serves as a basis for suggestions and recommendations to other companies that intend to make good use of advantages the ISO certification.

Fullerene (C60) is a unique carbon molecule that adopts a sphere shape. It has been proved that fullerene and some of its derivatives several disease targets. Fullerene itself is insoluble in water. So, fullerene application is hindered in medical field. In this study, a literature search was performed and all derivatives were collected. The fullerene binding protein, previously reported in literature were also retrieved from protein databank. The docking study were performed with fullerene derivatives and its binding proteins. The selected proteins include Voltage-Gated Potassium Channel, estrogenic 17beta-hydroxysteroid dehydrogenase, and monoclonal anti-progesterone antibody. The binding affinity and binding free energy were computed for these proteins and fullerene derivatives complexes. The binding affinity and binding free energy calculation of the co-crystal ligands were also carried out. The results show the good fitting of fullerene derivatives in the active site of different proteins. The binding affinities and binding free energies of fullerene derivatives are better. The present study gives a detail information about the binding mode of C60 derivatives. The finding will be helpful in fullerene-based drug discovery and facilitate the efforts of fighting many diseases.

This paper puts forward the key features of plausible time-evolving statistical distributions of the Scale and Spin of ‘eddies’, describing the phenomenon of turbulence. Statistical distributions generally describe the state of the system in equilibrium states, but describing turbulent flows demands non-equilibrium statistics, as there is energy dissipation due to viscosity of the fluid and variations in macroscopic properties of the system with time. The approach put forward proves to be highly advantageous to explain the variation of eddy scale, using the ‘Scale Displacement Equation’. It ascertains a huge gain in understanding characteristics of the fluids subject to high Reynolds numbers. The phenomenon of ‘Spin Interference’, which is responsible for the variation of eddy spin in the system, is also described intensively. The put forth Scale and Spin statistics, parametrized by time, demonstrate some interesting features that are fundamentally linked to the behaviour of fluids.

Wind energy is a renewable energy source that is emerging in a global scale, given the reduction in stocks of conventional energy sources and the growing interest in environmental protection. In addition, the European Union policies are moving to the same direction. Despite all the above, Greece has not efficiently developed policies and infrastructure about this valuable energy source. This paper focuses on the case of Lemnos island in the northern Aegean Sea. Although this island has gained wind farm investors’ interest, the total number of wind farms that are located on the island is not in accordance with its full potential regarding its average annual wind speed value. Τhe project’s main purpose is the development of a wind farm study in Lemnos, given the constraints on social and environmental criteria set by the Greek legislation for the proper functioning of the installation and the reduction of impacts on people and environment. The project's results can be directly used to promote investments in the island. Methods such as literature review, examination of case-studies, mapping and geographic information systems analysis were used.
