Effects of Pterocarpus Erinaceus Stem Bark Aqueous Extract on Anemic Rats.
Nadro, M.S, Modibbo, A.A

Abstract: The study was designed to evaluate the anti anemic effect of aqueous extract of Pterocarpus erinaceus stem bark in phenylhydrazine induced anemia in albino rats. The extract was also tested for safety. Acute toxicity studies revealed that values up to 5 g/kg body weight did not produced any visible effect. The dosages 250 and 500 mg/kg body weight fed the rats in this study were quite safe. Anemia was induced by administration of 80 mg/kg body weight of phenylhydrazine to the rats. The anemic rats were treated orally with 250 and 500 mg/kg body weight of aqueous extract of Pterocarpus erinaceus stem bark for fourteen days. Oral administration of 250 mg/kg body weight of aqueous extract to anemic rats significantly increased (P< 0.05) serum level of hematological parameters PCV from 40.15 to 54.15, Hb from 11.95 to 13.60, there were significant improvements in RBC, WBC, Neutrophil, Lymphocytes, Platelets, MCV, MCH, and MCHC of the treated rats when compared to the control. Also some serum biochemical parameters were tested. There were significantly reduced (P<0.05) serum levels AST (13.75), ALT (6.67) when compared to control. Similarly, the serum levels of Albumin, bilirubin, Urea, Creatinine and lipid peroxidationsignificantly improve when compare with the control group. The anemic rats fed with 500 mg/kg body weight showed significant improvement in both hematological and biochemical parameters tested. But the difference in values between treated groups (250 and 500 mg/kg body weight) has no significant different. The results suggest that Pterocarpus erinaceus stem bark is safe for use and may use in managing anemia in rats.

BER Performance of CRC Coded LTE System for Various Modulation Schemes and Channel Conditions
Md. Ashraful Islam, Dipankar Das , Halida Homyara , A. Z. M. Touhidul Islam

Abstract: In this paper we presents the bit error rate (BER) performance of the Cyclic Redundancy Check (CRC) coded Long Term Evolution (LTE) system under various digital modulations (BPSK, QPSK and 16PSK) over an additative white gaussian noise (AWGN) and other multi path fading (Raleigh and Rician) channels. It is apparent from the Matlab based simulation study that the proposed LTE system outperforms with BPSK as compared to other modulation schemes under AWGN noisy and Rayleigh and Rician fading channels. The transmitted data is found to have retrieved effectively at the receiver end under the implementation of CRC coding/decoding algorithm. It has been also predictable that the performance of the CRC-based LTE system degrades with the increase of noise power.

Application of Organic Manure and Mycorrhizal for Improving Plant Growth and Yield of Temulawak (Curcuma xanthorrhiza Roxb.)
Samanhudi, Ahmad Yunus, Bambang Pujiasmanto, Muji Rahayu

Abstract: Problems encountered in the development of herbal medicine industry is that most of the raw materials (80%) came from the forest or natural habitats and the rest (20%) of the results of traditional cultivation. Provision of raw materials still rely on the natural occurrence of genetic erosion has resulted in some important medicinal plants such as ginger, turmeric, temulawak, and kencur. This research was conducted in the District of Karanganyar, Central Java. The research is focused to improve cultivation techniques of temulawak plants (Curcuma xanthorrhiza Roxb.) by using various types of organic manure (chicken, goat, and cow) combined with various dose levels of arbuscular mycorrhizal fungi (AMF) application. The purpose of this research is to gain a steady cultivation technology through the use of organic nutrients and arbuscular mycorrhizal fungi so as to increase the production of temulawak plants. The results showed that goat manure can significantly increase the growth and yield of temulawak on every variable except plant height compared with other manure (chicken and cow). Mycorrhizal treatment at a dose of 10 g/plant capable of improving growth in a variable of leaves number, fresh weight of plant, dry weight of plant, and fresh weight of rhizomes. No interaction between organic manure application and mycorrhizal treatment dose on all observation variables growth and yield of temulawak.

Procurement Function Position Analysis
Dr. H. Zakaria Ismail

Abstract: In a company/organization in large to get people who are competent in their respective fields submitted to the recruitment section of the civil service. In a small organization, every leader can do alone withdrawal of labor, selection and placement without the help of experts (personnel department). There are several important steps that must be performed prior to recruitment and selection process that determines the type of labor or employee qualities desired for each position, and details regarding the number of employees who will be entrusted with the job respectively. So the first step in the management of personnel is getting which the right people, both the quality and the quantity corresponding to expect an organization/company. The method commonly used to determine the type or quality of manpower required is called job analysis, while the methods commonly used to determine the amount or quantity of labor is called work-load analysis (analysis of workload and study time (study time). Kepegewaian The management has extensive functions, so in this paper is only limited in the job analysis.

Factors affecting to effective eLearning: Learners Perspective
Dilrukshi Gamage, Shantha Fernando, Indika Perera

Abstract: eLearning is a method of delivering education via electronic means. Timely it is online learning as education or learning happens via world wide web. Effectiveness in eLearning with reference to the learner is whether he/she could meet the learning goals while learning online. In this research it has tried to identify the meaning of learning effectiveness with regard to users’ perspective and the factors affecting the effectiveness of eLearning. In order to conduct the research 121 active online eLearning participants have been interviewed and observed. Qualitative method of Ground theory and Quantitative analysis methods of Principle Component Analysis were used in order to process data and the results provide 10 factors that affect effectiveness in eLearning. At the same time it highlights and ranks the 10 important dimensions which any eLearning provider should attempt to address in providing a successful eLearning practice. Among all, the top 5 ranks were 1.Interactivity, 2.Collaboration3.Motivation 4.Network of Opportunities 5. Pedagogy. This research uniquely identified a ranking to the dimensions by the users’ perspective and also a new dimension, Network of Opportunities which was ranked under top 5 and should be addressed by any eLearning module in the future to provide an effective learning.
