Feed consumption, body weight gain, feed conversion ratio (FCR), carcass characteristics, water consumption, mortality, protein efficiency ratio, lysine efficiency ratio, efficiency of energy utilization, relative water consumption٫ production efficiency factor were studied. Two hundred unsexed broiler chicks, 28 day-old (Ross 308) were used. The Chicks were randomly distributed into 2 treatments experimental groups, designated T1 and T2, each group has 4 replicates of 25 chicks. Birds were fed the experimental diets for 3 weeks. They were fed finisher diets from 29 to 49 day old, in which fish oil was added to the iso-calaric and iso-nitrogenous diet, T1 0% (Control group) and T2 3% fish oil. Two rations (iso-nitrogenous and iso-caloric) were formulated according the requirement of (NRC) National Research council. Adding fish oil improved feed intake, body weight, weight gain, carcass weight, dressing percentage, protein ratio efficiency, efficiency energy utilization, lysine efficiency and production efficiency factor were significantly affected (P<0.01) and improved water intake, feed conversion ratio were significantly affected (P<0.05) of broilers for the three weeks. No significant differences were observed for relative water intake. Therefore it is concluded that adding fish oil based diets improved broiler performance and feed utilization.

The Inclusive Educational Policy of Maldives (Ministry of Education, 2013), declares that all students should be given equal educational opportunities regardless of their physical, intellectual, social, emotional or other conditions. The aim of this study was to find out what teachers believe, perceive, and feel about their schools’ readiness for inclusive education, with regard to the school leadership, school climate, curriculum instructions, individual student support, and teachers’ knowledge, skills and attitudes. The secondary purpose was to investigate the main challenges that deter inclusivity in the four government schools of Hithadhoo, Addu. A mixed approach with survey and focus group interview methods were used in the study. A total of 153 teachers participated in the survey and 10 teachers were in the focus group sessions. The findings revealed that in general, teachers had a positive view towards all the readiness factors related to inclusive education. However, the results indicated substantial challenges that may impede successful implementation of inclusive education. These challenges include lack of knowledge and skills on inclusive education, lack of facilities, lack of awareness among all stakeholders, curriculum difficulties, and time restrictions.

Using the classic example of the series Twilight, we can see how society plays a critical role in our thought process, and examine the dangers it can create by leaving some vulnerable to negative lifestyles. Taking a closer look at the science behind how our brain processes information, we can see how problems may arise. Addictions caused by social programming leaves much concern for those who experience the cognitive dissonance created by their surroundings. It is our social responsibility to ensure people are not establishing unhealthy lifestyles or destructive behaviors. By understanding the mechanics of the mind, we can help find healthy solutions for fantasy to be enjoyed without interrupting the livelihood of others.

It is important to initially understand historical and philosophical trails of the emergence of social capital concept before studying its implications to agricultural development through the stakeholders’ interactions. The emergence of social capital concept can be traced back from the classic social theories of Durkheim and Marx as well as other contributed classic scholars in social and economic theories. The concept originated when the forethought of morality conscience, solidarity, cooperation, morality, norms, values, and commitment were brought up to the period of people’s movement. Social capital does not have one single definition because the concept requires a context to define its meaning. Along the years of concept’s development, experts have found a common ground that the definition of social capital can be seen in the context of a social relation of the actors in achieving their common goals. Many empirical researches had been conducted to study social capital in the agricultural development to learn the social capital elements in mutual trust, reciprocity, and network. Many researches also had found that higher social capital level in people, organization, or community, contributes to a better agricultural development outcome. Therefore, social capital becomes one of the significant elements in pursuing development objectives and accountabilities through stakeholders’ social interactions.

Artificial neural networks are complex networks emulating the way human rational neurons process data. They have been widely used generally in: prediction, clustering, classification, and association. The training algorithms that used to determine the network weights are almost the most important factor that influence the neural networks performance. Recently many meta-heuristic and Evolutionary algorithms are employed to optimize neural networks weights to achieve better neural performance. This paper aims to use recently proposed algorithms for optimizing neural networks weights comparing these algorithms performance with other classical meta-heuristic algorithms used for the same purpose. However, to evaluate the performance of such algorithms for training neural networks we examine such algorithms to classify four opposite binary XOR clusters and classification of continuous real data sets such as: Iris and Ecoli.

This research work describes the translational motion analysis of unmanned aerial vehicle (UAV). Since the center of mass of the receiver is time–varying, the equations are written in a reference frame that is geometrically fixed in the aircraft. Due to the fact that aerial vehicle simulation and control deal with the position and orientation of the UAV, the equations of motion are derived in terms of the translational and rotational position and velocity with respect to the aircraft location. The formation relative motion control is a challenging problem due to the coupled translational and rotational dynamics. As the translational vector depends on the current attitude and its angular velocity, and some of the attitude constraints also couple the position and attitude of the spacecraft, it makes the formation control problem high dimensional. This work develops UAV stability conditions, including translational vector maneuverability condition and included angle condition between the translational and the rotational motion of UAV system, and then presents two methods to calculate the UAV attitude. Both of the two methods need first design the optimal trajectory of the translational vector, and then use geometric and nonlinear programming methods to calculate the target trajectory. The validity of the proposed approach is demonstrated in a UAV by using MATLAB. The performance of the translational motion control is evaluated by the simulated results.

Big data is a data beyond the storage capacity and beyond the processing power is called big data. Big data term is used for data sets it’s so large or complex that traditional data, it involves data sets with sizes. Big data size is a constantly moving target year by year ranging from a few dozen terabytes to many petabytes of data means like social networking sites, the amount of data produced by people is growing rapidly every year. Big data is not only a data, rather it become a complete subject, which includes various tools, techniques and framework. It defines the epidemic possibility and evolvement of data both structured and unstructured. Big data is a set of techniques and technologies that require new forms of assimilate to uncover large hidden values from large datasets that are diverse, complex, and of a massive scale. It is difficult to work with using most relational database management systems and desktop statistics and visualization packages exacting preferably massively parallel software running on tens, hundreds, or even thousands of servers. Big data environment is used to grab organize and resolve the various types of data. In this paper we describe applications, problems, and tools of big data and gives overview of big data.

In recent years, underground mines have increasingly remained on the agenda with both difficult working conditions and problems such as collapsed and firedamp explosion in our country and in the world. In terms of life safety of miners and their health, mine sites are required to be continuously monitored and controlled. This is difficult to achieve with existing wired systems due to the topography of mine sites. The applications have increased with the development of wireless sensor networks (WSN) technology in mine sites in recent years. This case has also caused an increase in studies on improving WSN performance. Especially, energy efficiency is very important for the WSN hardware with a low energy source. In this study, information about things to consider while using WSN technologies in underground mines and studies on their performance has been provided.

Despite investments made in maternal health in the developing world, and a free maternal health programme being launched in Kenya, maternal and neo- natal deaths in Bunyala Sub county remain high. This paper is based on a study which sought to determine the factors Influencing Mothers’ Choice of Birth attendance in Bunyala Sub-County, Kenya. This included an examination of the challenges they face in trying to access facility-based maternity services. A sample of 385 mothers living in different locations of the sub county were surveyed, using a structured questionnaire. Health personnel in the main health facility in each location were also interviewed, and focus group discussions held with Community Health Workers and Traditional Birth Attendants separately. Data revealed that the mothers of Bunyala sub county generally prefer the government facilities over the TBAs primarily due to availability of skilled staff, medicines and equipment. However, some mothers prefer the TBAs because of flexibility of payments, payments in kind, accessibility at odd hours, because of good relations, for cultural reasons,(to refrain from having male birth attendants), and for fear of the mandatory HIV testing done under the PMTCT program. The challenges faced were mainly the distance to the health facility, the in affordability of travel, the cost of medical drugs and supplies, poor roads, unavailability of night time ferry services, verbal abuse and negative attitudes from some skilled attendants, and long waiting hours.

The paper analysed the grain-size spectrum and textural parameters namely mean, sorting, skewness and kurtosis of Abu Dhabi coast in United Arab Emirates applying the ASTM sieves. For this purpose fifty seven samples were analysed. The results of the sieving analysis divulged that , samples of the study area range between -2.63 (pebble size) to 2-39 (Fine sands). The statistical analysis reveals that the sand is characteristically fine grained, moderately well sorted to extremely poorly sorted. The sand distribution is strongly coarse and leptokurtic in nature. Abundance of the medium sand to fine sand shows the prevalence of comparatively moderate- to low-energy condition in the study area. Linear discriminate function of the samples indicates an Aeolian, shallow marine deposition environment and less influence of fluvial (7 %) process.

The study of knowledge is one of the most fundamental and necessary components in today's world. A claim to knowledge should be evaluated to determine whether or not it is knowledge in its real sense. To conduct this sort of evaluation, understanding of what knowledge is and how much knowledge is possible is required. This paper provides an overview of the important aspects of knowledge, and with the help of epistemology tries to answer the most fundamental questions of what is knowledge? Moreover, how do we know what we know? The paper attempts to show the effect of culture on organizations and how foundational knowledge can help us develop logical decisions in a fluctuating environment. To manage an organization within evolving paradigm, knowledge of variation acts as a necessary requirement. As Deming defined management as a prediction, a leader must have skills to predict and adapt to its external environment. Most of the time organizations fail to observe the paradigm shift and couldn't adjust to the changing environment. The paper also discusses the effect of diverse culture and their respective interpretation of language. Thus, the paper highlights the necessity of understanding human psychology, attaining foundational knowledge and ability to validate the knowledge to establish a successful organization.

This research aimed to find out the substance of corruption as an extraordinary crime and the efforts that can be taken in eradicate corruption. This research is in the field of criminal law. This study is a normative-empirical research; a legal research that its study is statutory provisions (in abstracto) is linked with the field application (in concreto). The results of research showed that: 1) the substance of corruption is an evil act or reprehensible by law qualified or labeled as a form of corruption. Acts of corruption assessed as an extraordinary crime because of its systematic and wide-ranging impact, and contrary to the interests of the country in general. 2) the arrangement of corruption involves two major aspects of prevention and prosecution aspects. Establishment of legislation was based by desire to bring state enforcement are clean and free from corruption as a policy basis. 3) Efforts to eradicate corruption can be divided into two, i.e prevention, and curative. Prevention undertaken by government and law enforcement agencies is still low, so it needs to be further improved. Criminal sanctions imposed on the corruptor, also tend to just apply the minimum criminal sanctions. Types of corruption are most prevalent in Southeast Sulawesi, Indonesia is corruption related to acts of abuse of authority or position.

Division is the “inverse” of multiplication so basic division consist of a sequence of subtraction, which are just additions of the negations of the subtrahends; Therefore, CS addition can be used in the arithmetic for division as well. Division is, however more complicated than multiplication, in that subtrahend (multiple of divisor) chosen at any steps depends on the magnitude result of the preceding subtraction and that magnitude is not readily available with CS representation. Assuming two’s complement representation, subtraction with carry save representation is carried out in usual manner of the farming the one’s complement of the subtrahend and then adding that with a 1 also added into the least significant bit position subtraction is performed by adding the negation of the subtrahend, which two’s complement representation consist of the one’s complement addition of 1 in the least significant bit position.

This innovative glass design will carry an OLED based display controlled via nano Ardiuno board having Bluetooth connectivity with a Smartphone to exchange information along with onboard accelerometer. We are using a tilt angle sensor for detecting if the driver is feeling drowsy. An alcohol sensor has been used to promote the safe driving habit. The glasses will be getting latest updates about the current speed of the vehicle, navigation directions, nearby or approaching sign broads or services like petrol pumps. It'll also display information like incoming calls or received messages. All this information will be obtained through a Smartphone connected via Bluetooth. Also the car mileage can be monitored with help of fuel sensor as the consumption of fuel is directly related to it. Abnormalities if detected will be immediately notified in the glasses. Also the angle of the tilt angle sensor can be defined and set by the user according to his needs. Also the main idea of using OLED glasses is that it is organic thereby helps in reducing the carbon footprint and is quite slim. Therefore it can be easily mounted on the specs without making it heavy. Also they higher level of flexibility and have low power drain and energy consumption

Fins are used to increase the rate of heat transfer to or from the environment by providing excess surface area. Fins performance can be increased by reducing perimeter by area ratio, using material with high coefficient of thermal conductivity(K) and by optimizing size and distance between fins over surface. Boundary layer generation over fin also effects heat loss widely. If boundary layer(BL) of one fin intersects BL generated from other fin then fin performance reduces. Same concept is also applicable on Macro-fins. In our paper we simulated thermodynamic boundary layer over Bell shaped fins (Gaussian distribution) and used these fins to model increase in heat transfer with surface roughness

Pozzolana is defined as Siliceous and aluminous material which reacts with calcium hydroxide in presence of water at room temperature to form strong slow-hardening cement. Pozzolana has the advantage of reduction of leachibility of calcium hydroxide liberated during the setting and hydration of cement. In Khartoum Refinery five to ten tons per week of spent catalyst are produced in fine powder, this quantity is sent to dumping sites or landfills. In this study pilot experiments were successfully carried out at different ratios to produce cement. The RFCC spent catalyst samples were subjected to chemical analysis to determine the content of Al2O3, SiO3,TiO3, CaO and V2O5 …..etc. These were found to be 49.5, 41.1, 0.32, 1.4 and 0.09 percent respectively, other compounds are, Na2O, MgO, P2O5,SO3, K2O, MnO,Fe2O3,Co3O4 and NiO2 with. It is found that the percentages of SiO2, Al2O3, and Fe2O3 amount up to 91.5% that is above the ASTM standard C618:2003 which stipulated that the minimum of such compound is 70 %. Physical properties of RFCC spent catalyst were also carried out including, crystallinity and Pozzolanicity index. The cement produced was tested for compressive strength, consistency and setting time .It is concluded that RFCC spent catalyst in Khartoum Refinery is a Pozzolanic material and up to 30% replacement from Portland cement (blended cement) complies with the Sudanese and European Standards No SSMO 3998:2011and EN-197-1:1992 respectively. The study shows that the compressive strength of blended Pozzolanic cements decreases with increasing Pozzolana content. From the foregoing, it is recommended to use RFCC spent catalyst with Portland cement as blended cement to produce mortars for construction and concrete.

A healthy pregnancy requires strict coordination of genetic, physiologic, and environmental factors. The relatively common incidence of infertility and pregnancy complications has resulted in increased interest in understanding the mechanisms that underlie normal versus abnormal pregnancy. The peptide hormone adrenomedullin has recently been the focus of some exciting breakthroughs in the pregnancy field. Adrenomedullin (ADM) is a 52-amino acid peptide with structural homology to calcitonin gene-related peptide (CGRP) initially isolated from human pheochromocytoma. ADM is synthesized by many mammalian tissues including the adrenal medulla, endothelial and vascular smooth muscle cells, myocardium and central nervous system. ADM binds to plasma membrane receptors composed of calcitonin receptor-like receptor (CRLR), a member of serpentine receptor superfamily, and receptor activity modifying protein (RAMP) type 2 or 3. ADM has also some affinity for CGRP receptor composed of CRLR and RAMP1. Supported by mechanistic studies in genetic animal models, there continues to be a growing body of evidence demonstrating the importance of adrenomedullin protein levels in a variety of human pregnancy complications. With measurement of foetal resorption sites, we can examine the importance of adrenomedullin, a peptide hormone in pregnancy which alters due to genetic, physiologic and environmental factors. A growing body of evidence illustrates AM as a pivotal component in normal physiology and disease with marked beneficial effects in the host defense mechanism.

today’s most important concern of Bangladesh is power generation. Government has planned a 1320 MW coal-fired power station at Rampal near Sundarbans. Environmentalists have indicated that this plant will face environmental issues. So we tried finding the capability of Sundarbans to face carbon emissions. We figured out approximate carbon emission of that power plant using an arbitrary operational model. We found 3.16MKg of carbon emission daily. We used mangrove’s carbon sequestration rate to calculate the carbon tolerance level of Sundarbans and found approximately 4.2 MKg of carbon per day.The amount of emission we found here is marginal with the ability of Sundarbans as it is already contributing to sequester carbon from other sources. We studied and showed technology wise carbon reductions. It is possible to reduce 90% to 95% carbon emissioby using these technologies. We recommend these advanced technologies to ensure sundarbans' environmental safety.

Vocabulary is the first hurdle for English learners to over- come. Instead of simply showing a word again and again, we come up with an idea to develop an English news article search engine based on users word-reciting record on Shanbay.com. It is designed for advanced English learners to find suitable reading materials. The search engine consists of Crawling Module, Document Normalizing module, Indexing Module, Querying Module and Interface Module. We propose three sorting & ranking algorithms for Querying Module. For the basic algorithm, five crucial principles are taken into consideration. Term frequency, inverse document frequency, familiarity degree and article freshness degree are factors in this algorithm. Then we think of a improved algorithm for the scene in which a user read multiple articles in the searching result list. Here we adopt a iterative & greedy method. The essential idea is to select English news articles one by one according to the query, meanwhile dynamically update the unfamiliarity of the words during each iterative step. Moreover, we develop an advanced algorithm to take article difficulty in to account. Interface Module is designed as a website, meanwhile some data visualization technologies (e.g. word cloud) are applied here. Furthermore, we conduct both applicability check and performance evaluation. Metrics such as searching time, word-covering ratio and minimum number of articles that completely cover all the queried vocabulary are randomly sampled and profoundly analyzed. The result shows that our search engine works very well with satisfying performance.

the proximate composition, energy content and sensory properties of complementary foods prepared from sorghum and African yam bean flour blends were investigated. The sorghum flour (SF) was blended with African yam bean flour (AYBF) in the ratios of 90:10, 80:20, 70:30, 60:40 and 50:50 and used for the production of complementary foods. The complementary foods produced were evaluated for proximate composition, energy content and sensory qualities using standard methods. The proximate composition of the samples showed that the protein content of the complementary foods increased gradually with increased level of African yam bean flour addition from 8.64% in 90:10 (SF: AYBF) to 13.44% in 50:50 (SF: AYBF) samples, while carbohydrate decreased. In the same vein, the energy content of the samples also increased with increased supplementation with African yam bean flour from 368.84KJ/100g in 90:10 (SF: AYBF) to 382.98KJ/100g in 50:50 (SF: AYBF). The sensory evaluation carried out on different samples of complementary food after reconstitution into gruels with boiling water showed that the formulation prepared from 100% sorghum flour used as control was most acceptable by the judges and also differed significantly (p≤0.05) from the other samples in flavour, texture and taste. However, the sample fortified with 50% African yam bean flour was scored highest in colour.

This paper demonstrates how the short messaging service (SMS), popularly known as ‘texting’, has facilitated production of solutions to farm issues using the Farmers’ Text Centre (FTC) of the Philippine Rice Research (PhilRice) as the case study. Text messages registered in the FTC database in 2010 covering one cropping season were discourse analyzed. Interpretive qualitative research particularly the Grounded Theory was employed to interpret/theorize said data. Since texting is a new, emerging discourse in agricultural development, Grounded Theory allows the explication of theoretical accounts that explain its existence and impact. Results indicate that timing (queries received within working days from 8am to 5pm get speedy response), content (the easier the question the faster it gets reply), length (the shorter the message the better) and clarity of the query/text message, as well as cultural factors (such as greetings and terms of respect) are all important governing factors in texting for farm use. Moreover, analysis reveals that the series of text messages sent back and forth by farmers and agricultural specialist in FTC suggests a dynamic process of negotiation, rather than passive information sharing. The analysis further reveals that texting has allowed farmers to have access to a ‘negotiated’ knowledge rather than a standard scientific recommendation vis-à-vis the solution to their farm issues. The term ‘negotiated’ implies that farmers are actively involved in knowledge production via texting. ‘Textholder’ is coined in this paper to describe farmers and agricultural specialists as co-creators of knowledge in texting, as opposed to their traditional role as knowledge generator and user, respectively. From the analysis, reflections, implications, and theoretical contributions are drawn in relation to the value of SMSing in agricultural extension and communication.

This paper presents an application of Chaotic differential evolution optimization approach meta-heuristics in solving transmission network expansion planning (TNEP) using an AC model associated with reactive power planning (RPP). The reliability–redundancy of network analysis optimization problems implicate selection of components with multiple choices and redundancy levels that produce maximum benefits, can be subject to the cost, weight, and volume constraints is presented in this paper. Classical mathematical methods have failed in handling non-convexities and non-smoothness in optimization problems. As an alternative to the classical optimization approaches, the meta-heuristics have attracted lot of attention due to their ability to find an almost global optimal solution in reliability–redundancy optimization problems. Evolutionary algorithms (EAs) – paradigms of evolutionary computation field – are stochastic and robust meta-heuristics useful to solve reliability–redundancy optimization problems. EAs such as genetic algorithm, evolutionary programming, evolution strategies and differential evolution are being used to find global or near global optimal solution. The Differential Evolution Algorithm (DEA) population-based algorithm is an optimal algorithm with powerful global searching capability, but it is usually in low convergence speed and presents bad searching capability in the later evolution stage. A new Chaotic Differential Evolution algorithm (CDE) based on the cat map is recommended which combines DE and chaotic searching algorithm. Simulation results and comparisons show that the chaotic differential evolution algorithm using Cat map is competitive and stable in performance with other optimization approaches and other maps.

A municipal water reticulated pipeline network in Owerri, Nigeria previously analyzed by Simultaneous Loop Flow Correction Method, was re-evaluated using Basic Discrete Systems Analysis Method. This study was carried out to validate the results of the earlier study and decide if the water pipeline network flow characteristics can also be evaluated in a later study for more insight. This study sought, produced a better representation and explanation of the head loss and discharge profiles for the water pipeline network. The water pipeline network consists of twenty-four discrete system (pipe elements) and pipe connections become the nodes which consists of sixteen nodes. These pipeline elements were viewed as discrete systems and flow equations, from first principles, are formulated for each element. Plots were developed to show the nodal head loss, nodal pressure, pipe elements corrected head loss and pipe elements corrected discharge being affected by the pipe diameter and length. The plots revealed that the solutions which were obtained as corrective flow parameters (head loss, pressure and discharge) for the water pipe network described the flow profiles of the pipe network and the flow fluctuations being experienced in the pipe network.

The motion of a multi-fluid flow is of interest in the oil and gas industry. The flow characteristics aid or impede production rate. This study analyses two phase fluid flow characteristics consisting of crude oil and natural gas, in straight pipes of the same internal diameter, using homogenous model. Flow values were obtained from a Niger Delta flow station and predetermined experimental flow equations were used to determine the pressure drop in order to comprehend the flow characteristics in the pipeline. An average total pressure loss (∆PT) of 0.075 MPa was obtained in the laminar flow category at 0.006228 MPa/m and an average total pressure (∆PT) of 27.896 MPa in turbulent flow category at 2.325 MPa/m in a pipe length of 12 metres. Graphs were plotted to show the influence of the calculated flow parameters on the fluid flow. The graphs aided in depicting the flow regimes in the pipeline. These are universally dominant parameters in the oil and gas industry as they significantly impact on the transportation of crude oil from oil wells or reservoirs to the process plants. These results may be used as a baseline and guide to compare realistic measurements in similar flows.
