Research question was answered using frequency counts, total score and means. Findings of the study revealed that democratic leadership style in academic libraries studied has positive influence on subordinates’ job performance because it results in high employees’ productivity. This style of leadership tends to have work groups that were very productive and subordinates showed a high degree of satisfaction on the job. Among others, the researchers recommended that heads of academic libraries should be encouraged to adopt democratic leadership style since it yields higher result in job performance of subordinates and consequently to users’ satisfaction with library services.
Effect of management systems on growth and conformation of male lambs of Kachhi and Kooka sheep

A study was carried out on 12 male lambs under two management systems at the Department of Livestock Management. Six lambs from each breed were reared under intensive (A) and semi-intensive (B) management systems. The Kooka lambs comparatively gained more body weight per week (4.84±0.27% and 3.25±0.09%, respectively) than Kachhi lambs (4.03±0.12% and 2.61±0.21%, respectively) of group B and A, respectively. The average per week increase in body weight of lambs in group B was significantly higher (P<0.05) than that of group A. The average body weight of Kooka and Kachhi lambs of group B was significantly (P<0.05) higher than Kachhi and Kooka lambs of group A. Per week increase in body conformation in respect of height, girth and length (1.55±0.08%, 1.32±0.04% and 1.82±0.01%, respectively) of Kooka and Kachhi (1.00±0.03%, 1.06±0.02% and 1.54±0.06%, respectively) lambs of group B was comparatively higher (P<0.05) than Kooka (0.97±0.07%, 0.86±0.03% and 1.37±0.07%, respectively) and Kachhi (0.77±0.04%, 0.68±0.07% and 0.96±0.02%, respectively) lambs in group A. The overall mean height, girth and length of male Kooka lambs of group B were significantly (P<0.05) higher than Kachhi lambs of group A and group B but relatively similar to that of Kooka lambs in group A. Result concludes that, the male Kooka lambs gained more body weight and body conformation than that of male Kachhi lambs under both management systems (intensive and semiintensive management system).
DETERMINANTS OF FOREIGN PATIENTS LOYALTY OF MEDICAL TOURISM IN MALAYSIA: TRUST AND PERCEIVED VALUE AS MODERATORS

Medical tourism is one of the fastest-growing tourism sectors in the world generally and in Malaysia specifically , which has significantly contributed to the economic development (Han & Hyun, 2015; Heung, Kucukusta, & Song, 2011). Recent studies have estimated that the worldwide medical-tourism industry generates nearly U$D 60 billion per year, with a growth rate of about 20% annually (Heung, Kucukusta, & Song, 2011; Liu & Chen, 2013). The main aim of this study was to examined the moderators‟ effect role of perceived value and trust.

Effects of Functional Appliance Therapy on the Depth of the Pharyngeal Airways: Activator vs. Forsus

Reduction in pharyngeal airway dimensions has been known to be associated with mandibular retrognathism [3], mainly relative to backward posture of soft palate and tongue, which increases chances of certain respiratory problems, such as snoring, and Obstructive Sleep Apnea (OSA) [4]. Nowadays, several appliances are used similarly in OSA patients to relocate tongue, soft palate, and hyoid bone in an aim to increase pharyngeal dimensions, and to subsequently improve respiratory function during sleep in these patients [5].
Curvature-based Tortuosity Evaluation for Infant Retinal Images

The clinical recognition of abnormal retinal tortuosity is significant in the diagnosis of several ocular and systemic diseases. An automatic evaluation and quantification of tortuosity would help in the early detection of such pathologies. We applied two tortuosity evaluation approach based on continuous curvature to a dataset of 45 infant fundus images. Performance evaluation is done on classification accuracy of three classifiers-Naive Bayesian classifier and k-nearest neighbor classifier, and K-means clustering algorithm, by comparing the estimated results against ground truth from expert ophthalmologists. Results show that different numerical methods provide different tortuosity values for same retinal vessels however have the potential to detect and evaluate abnormal retinal curves. The best classification accuracy of 87.3% is achieved by the method 2 using K-nearest neighbor classifier. Keywords: Retinal vessels, curvature, tortuosity
Polycyclic Aromatic Hydrocarbons (PAHs) and Organochlorinated Pesticides(OCPs) in Yellowtail (Seriola lalandi) from three Spatially Distinct Locationsalong the Coast of South Africa: Levels, Sources and Fish Size Effec

Polycyclic aromatic hydrocarbons (PAHs) and organochlorinated pesticides (OCPs) such as dichlorodiphenyltrichloroethane (DDT), endosulfan and benzenhexachloride (BHC) were evaluated in yellowtail (Seriola lalandi) fish species. These hardous compounds were studied in fish sampled from three locations: Port Elizabeth, Yzerfontein and Struis Bay. The aim of the study was to investigate the profiles, levels and sources of PAHs and pesticides in yellowtail from the selected locations in relation to fish size and lipid content. Significant variations (p<0.05) were observed in the levels of PAHs measured in fish sampled from the three locations. Fish from Port Elizabeth had the highest PAHs concentrations (533.95 ± 34.36), followed by Yzerfontein (221.40 ± 33.03) and Struis Bay (88.97 ± 2.83) μg/kg wet weight. benzo(a)pyrene (as PAHs biomarker) exceeded the recommended EU limit (2 μg/kg) in samples from Port Elizabeth and Yzerfontein whereas samples from Struis Bay did not exceed. DDT was detected only in samples from Port Elizabeth and Yzerfontein with mean total concentrations (7.48 ± 5.18 and 11.14 ± 1.44 respectively) not significantly different. Fish size (weight) correlated positively with lipid content (0.65; p<0.01) and a stronger positive correlation with AE©PAHs (0.83; p<0.01). PAHs input source in fish from Port Elizabeth reflected a mixture of petrogenic and pyrogenic whereas, Yzerfontein and Struis Bay showed input source as petrogenic. In conclusion, consumption of large sized fish in locations with high PAHs burden can predispose consumers to health risk. Further investigation into human dietary exposure with the species is recommended.
Significance of TGF-β1 and Catheps in E expression in gastric adenocarcinoma and precancerouslesions

Background and aim: 40 cases with gastric lesions comprise the material of this study. These include 40 paraffin blocks selected from gastric specimens (30 cases were obtained by endoscopy and 10 cases were surgical specimens) received at the pathology department, Faculty of Medicine, Zagazig University in the period from September 2013 to September 2014. The aim of this study to examine the expression of transformed growth factor beta 1 (TGF-β) and Cathepsin E (CTSE) in gastric cancer and gastric precancerous lesions and to correlate between these markers and clinicopathological parameters. Methods: Immunohistochemical analysis of TGF beta and Cathepsin E were performed using 40 cases for chronic superficial gastritis, chronic atrophic gastritis, chronic atrophic gastritis with intestinal metaplasia, gastric dysplasia and gastric cancer. Results: In cases of chronic gastritis, we observed only TGF-β1 reactivity in the cytoplasm of inflammatory cells mainly plasma cells. In intestinal metaplasia and dysplastic lesions, the reactivity to TGF-β1 was more intense than in normal mucosa, especially in the cytoplasm of the Goblet cells. TGF-β1 was expressed in 88.8% of incomplete intestinal metaplasia. TGF-β1 expression was detected in intestinal type of gastric adenocarcinomas in 100% of well differentiated adenocarcinoma, 50 % of moderately differentiated adenocarcinoma and 66.6% of poorly differentiated adenocarcinoma. TGF-β1 was expressed in 50% of papillary carcinoma and mucinous carcinoma. TGF-β1was expressed in 100% of signet ring carcinoma. In chronic gastritis without atrophy or intestinal metaplasia, expression of cathepsin E is clearly observed in the fundic and pyloric glands of stomach. CTSE immunestaining was detected in 100% of type II (incomplete intestinal metaplasia) it is negative in type I IM (complete intestinal metaplasia). CTSE was expressed in 57.14% of gastric cancer. More undifferentiated gastric tumors tend to increase expression of CTSE in tumor lesions (poorly differentiated adenocarcinoma> moderately differentiated adenocarcinoma> well differentiated adenocarcinoma). Cathepsin E was negative in mucinous and papillary carcinoma (100%) negative expression. Cathepsin E was positively expressed in 100% of signet ring carcinoma. Conclusion: The alterations of expression of TGF and cathepsin E can determine the histological variants of gastric cancer (GC). Cathepsin E could be a marker for signet ring carcinoma Understanding the expression pattern of TGF beta and Cathepsin E in gastric cancer allows them to be used as future therapeutic targets.

A QoS-oriented distributed routing protocol for hybrid wireless networks

2 Abstract: With the increasing level of wireless communication in today's environment, people often required QOS for sharing their data between the nodes. For affording QOS to the user, many researchers proposed a very few methods to provide QoS guaranteed routing for hybrid networks, they strive to improve the network capacity and reliability but they evade constrain in QOS. For this problem our main objective of this paper is to improve the QOS and efficiency of routing approach with constrains over hybrid wireless data streaming using QOS_DARP protocol and MAR. This aims to develop the QOS based reliable architecture against the hybrid wireless routing issues. The system also aims at providing both proactive and reactive solutions for effective routing. The goal of this paper is to providing efficient dynamic routing management to deal the challenges of data transmission and data streaming in hybrid mobile environments.
Non Data Aided Phase Estimation Techniques for QAM Communication System: A Review

— Phase recovery is a problem of paramount importance in synchronous digital communication system, especially for high bit rate signaling such as QAM modulation. The phase estimation must be performed in a blind manner, means without using known training sequences of known transmitted symbols i.e. known as non-data-aided (NDA) method. This is done to obtain high efficienc.y. Accuracy in estimation of phase is very important because if it is little off, cross talk occurs. Recent advances in phase estimation have paved the way for simple calculation and improved results. Many authors have addressed this topic over the last year, yielding a wide variety of recovery methods. In this paper, complete review for NDA phase estimation techniques explained with its achievements and limitations.
Analysis of Determinant Factors to Loan Repayment among Broiler Farmers in Enugu State, Nigeria

Analysis of loan repayment among rice farmers in Enugu State, Nigeria was studied using one hundred and eighty respondents. These respondents were selected using multi stage sampling procedure and purposive selection procedure. The objectives of the study were to describe the socio-economic characteristics of the broiler farmers, identify the various broiler management practices the farmers put their credit into, assess the determinant factors influencin loan repayments among the farmers and identify the constraints to loan repayment by the farmers in the study area. Structured questionnaire was used to collect information for the study. Data collected were analyzed using descriptive such as frequency distribution table and percentage responses, inferential statistics such as Logit model and factor analysis. The results of the study indicated that the sampled farmers were youthful, females, married, and had large household size and farming experience of above 11 years. Also, microfinance and commercial banks were the major sources of credit to the farmers. In addition, the major uses the credit was put into by the farmers were in purchasing feeds and buying of drugs and vaccines. The determinant factors to rice farmers’ loan repayment ability were household size, extension services, membership of organization, farming experience, educational level and off-farm income. The constraints to the farmers’ ability to repay their loan were high interest rate, low productivity, high collateral, poor loan assessment and changes in bank policy changes. The need to enhance the farmers’ access to training, offfarm income and the need to give rebate to farmers that repay their loans at appropriate time were recommended. Keywords— Analysis, Loan, Repayment, Broiler, Farmers, Enugu State, Nigeria.
EFFECT OF FEEDING DIFFERENT INCLUSION RATES OF WATER HYACINTH [EICHHORNIA CRASSIPES (MART.) SOLMS] ON THE BODY WEIGHT GAIN OF GROWING DAIRY BULL CALVES

Twenty-four (24) Holstein Friesian-Sahiwal crossbred growing dairy bull calves with average weight of 87.30 kg were used to evaluate the effect of feeding water hyacinth (WH) on the Body Weight Gain (BWG) of growing dairy bull calves at the Dairy Training and Research Institute (DTRI), Dairy Farm, College of Agriculture and Food Science, University of the Philippines (UPLB), College, Laguna from August 2017 to December 2017. WH at 0, 10, 20 and 40% dry matter (DM) basis substitution of Napier grass in the total mixed ration (TMR) served as treatments in six (6) randomized complete blocks, each block consisting of calves at the same weight range. WH at 40% caused increased DM intake in calves but feeding WH to calves did not affect body weight (BW) gain of the calves. Therefore, WH can be used as an alternative feed source at an inclusion rate of 10-20% dry matter basis substitution of Napier grass.
Metabolic Profiling of Dunaliella salina Shifting Cultivation Conditions to Nitrogen Deprivation

Dunaliella salina is a model chlorophyte microalga in studying carotenoid metabolism and osmoregulation. Nitrogen depletion plays an important role in inducing β-carotene accumulation of D. salina cells. However, the underlying mechanism is still unclear. In this study, the metabolic profiling of D. salina cells during the process of nitrogen deprivation was performed by gas chromatography-mass spectrometry. A total of 78 metabolites were identified and quantified, including 16 amino acids, 19 sugars, 13 organic acids, 11 alcohols, 11 fatty acids, 4 amines and 4 others. Nitrogen deprivation induced changes in saturation of fatty acids by increasing saturated fatty acids and decreasing polyunsaturated fatty acids in D. salina. The relative levels of metabolites such as sucrose, maltose and organic acids, which act as carbon skeleton, were increased, in contrast, glycerol, myo-inositol which are related to the osmoregulatory mechanism, kept constant under nitrogen deprivation condition. The levels of proline, glutamic acid and other metabolites, which were involved in protective function, were increased in nitrogen deprivation condition. The precursors of these metabolites are the intermediates of the Calvin cycle and the TCA cycle. The results of this research might be applicable to the interpretation of metabolic synthesis and fatty acid production during process of nitrogen deprivation and provide a new method for accumulating high amounts of carotenoids in D. salina.

New, simple and cost effective UV-spectrophotometric method was developed for the estimation of Venlafaxine hydrochloride in bulk and pharmaceutical formulations. Venlafaxine hydrochloride was estimated at 225.27 nm in distilled water. Linearity range was found to be 4 24μg/ ml (regression equation: absorbance= 0.0684 × Concentration in μg/ml + 0.0038; r2= 0.9991). The apparent molar absorptivity was found to be 3.4 × 104 l mol-1cm-1 in distilled water. These methods were tested and validated for various parameters according to ICH guidelines and USP. The proposed method was successfully applied for the determination of Venlafaxine hydrochloride in pharmaceutical formulations (tablets and capsules). The results demonstrated that the procedure is accurate, precise and reproducible (relative standard deviation < 2%), while being simple, cheap and less time consuming and can be suitably applied for the estimation of Venlafaxine hydrochloride in different dosage forms and dissolution studies.
Acaricidal action of Plant Derivatives and Natural oils against two spotted spider mite, Tetranychus urticae Koch in Rose (Rosa sp.) ecosystem

The field study was conducted during summer 2015 at two different locations i.e., Allanganallur and Vadipatti blocks in Madurai district of Tamil Nadu to evaluate the efficacy of certain promising plant derivatives and natural oils against two spotted spider mites Tetranychus urticae Koch in Rose (Rosa sp.) ecosystem. The cumulative mean data from the present investigation revealed that among the different botanical extracts and natural oils evaluated, Tulsi leaf extract (Ocimum sanctum) @10%, Neem oil (Azadirachta indicia) @ 3% and Nochi leaf extract (Vitex negundo) @ 5% recorded the maximum per cent reduction of mites (71.80%, 71.12% and 70.25% at Vadipatti block and 73.97%, 73.37% and 72.77% at Allanganallur block) respectively, which were statistically on par in their efficacy in Rose ecosystem. With respect to the flower yield; amongst the different plant derivatives and natural oils evaluated, the highest per cent increase in flower yield was recorded in case of Tulsi leaf extract @ 10% (54.31% at Vadipatti block and 54.41% at Allanganallur block), Neem oil @ 3% (53.47% at Vadipatti block and 53.66% at Allanganallur block) and Nochi leaf extract @ 5% (51.68% at Vadipatti block and 53.24% at Allanganallur block) coupled with highest cost benefit ratio of 1:1.86 and 1:1.95 (Tulsi leaf extract @ 10%), 1:1.71 and 1:1.89 (Neem oil @ 3%) and 1:1.66 and 1:1.87 (Nochi leaf extract @ 5%) at Vadipatti block and Allanganallur block respectively which were statistically at par. Consequently in terms of per cent increase in flower yield and cost benefit ratio also, Tulsi leaf extract @ 10%, Neem oil @ 3% and Nochi leaf extract @ 5% were superior than other plant derivatives and natural oils evaluated, which can be presumed as ideal alternative option to synthetic chemical acaricides which are costlier as well for the management of T. urticae in Rose ecosystem.
Adaptive Routing Algorithms in Unstructured Peer-to-Peer (P2P) Systems

—There are a variety of peer-to-peer (P2P) systems for sharing documents currently available. According to their data organization, P2P systems are classified into two categories: structured and unstructured P2P systems. In structured P2P systems, peers are organized according to some mapping techniques, e.g. hashing function. Whereas in unstructured P2P system, peers are connected to each others randomly; resources are not moved to other peers but hosted on site. Unstructured P2P systems offer a more flexible and autonomous environment, as they require less control for the placement of resources and peers. This work focuses on experimenting on unstructured P2P systems. The challenge in unstructured P2P system is designing routing strategies that lead the user in finding the documents needed. Routing strategies in unstructured P2P system need to consider the dynamic aspects of P2P systems; peers are dynamic and constantly joining and leaving the system, network load changes continuously and resources are added and removed over the time. Therefore, the routing strategy must adapt to such changes to maintain its performance. We propose routing strategies that adapt to these changes through learning mechanisms. The learning mechanisms are conducted by observing the internal and external behaviors of the system. Internal behaviors reflect the internal state of peers such as peers’ interest and collection. External behaviors reflect the external state of the system such as network load. In order to measure the performance of the proposed routing algorithms, some common performance measurements are used. These are “response time” and “number of messages generated” or what is commonly referred to as efficiency, “number of answered and satisfied queries” and the “similarity of documents” or what is commonly referred to as effectiveness of retrieval system. The experiment results show that the proposed algorithms are capable of adapting to new changes. By learning to adapt, the system maintains its performance in terms of efficiency and effectiveness. Moreover, comparison with other similar algorithms also shows the superiority of the proposed routing algorithms. Thus, the proposed routing algorithms are good candidates for effective and efficient retrieval of documents in P2P systems.
