Elaeagnus angustifolia has wide range of distribution in the country and its oil has many food and health benefits. Its oil use for therapy of some disease included Dental diseases, diarrhea, stomach ulcers and prevention of bleeding. The purpose of this study was to investigate the physicochemical properties of the seed oil. Therefore Elaeagnus were collected of the surrounding gardens Semnan. Its core was separated. After drying, it was chopped by the mill, oil extraction was obtained by Soxhlet. Some traits were examined such as Peroxide value, acid and iodine value. 5% oil was obtained of Elaeagnus Angustifolia. The oil had high in linoleic acid and oleic acid its oil like sunflower oil and contains essential fatty acids omega-6 and omega-9 fatty acid. It also has good resistance to oxidation temperature. The mean iodine value was 120.73, oxidation stability 5:51 h, blue color 0.78 percent, red 2.79 percent, yellow 47.6%, peroxide 12.31 mill equivalents peroxide per kg of oil, non-soap compounds 5.17% , sterols 1283 mg/100gr oil, Tocopherol 94.3 mg/ 100gr oil, iron 0.62 ppm, copper 0.0366 ppm, Phospholipid 268.3 mg per gram, respectively.

The main purpose of this study is to scrutinize the role of interaction and its features (asking for agreement, prompting elaboration, paraphrasing, sharing) in a test of oral proficiency. To this end, 80 Iranian intermediate students (16-18 years old) participate in two tests of oral proficiency: one in which the participants do not interact with one another (individual format), and the other interact with a group of 5 members (group format). In the upshot, SPSS version 19 is run to analyze the collected data. The results reveal that test-takers performance differed significantly when they interact with one another. It is, also, shown that features of interaction affect the students’ fluency, accuracy, comprehension, and use of English differently. Key words: group interaction, oral proficiency testing, fluency, accuracy, comprehension, use of English

The facies architecture and depositional environments of the ‘X’ Field reservoirs have been studied in Wells NDI-A10, A12, A11, A7, A2P2 and A2, using wireline log data. The logs were examined and analyzed for reservoir identification, thickness distribution, continuity, and connectivity. The depositional environments were determined by closely comparing the log shapes of interest with the standard log motifs of Schlumberger (1985) and Emery (1999). Three deltaic sub-environments of deposition were recognized: beach-barrier, river mouth bar and shoreface. The sequence stratigraphic concept has been applied to these sub-environments. Six reservoirs: I, J, K, L, M and N, and five stratigraphic sequences: SEQ.I, SEQ.II, SEQ.III, SEQ.IV and SEQ.V, were identified. The reservoirs were deposited as progradational parasequences during a high-frequency highstand systems tract, while the shale units underlying and overlying the reservoirs were deposited as retrogradational parasequences. The consistent alternation of progradational sand units and retrogradational shale units have been interpreted as a tripartite union of source rock, reservoir and seal, essential for hydrocarbon generation, accumulation, and trapping in the ‘X’ Field. Well-to-well correlation across the entire field allowed a reconstruction of the depositional history of the reservoirs and delineation of the reservoir geometry. There was more development of the reservoirs in the northeastern part of the field which has been interpreted as the direction of sediment supply, but the overall depositional trend is similar to that of the present-day Niger Delta.

The major aim of current study was to explore the relationship between examination anxiety and academic achievement of students at university level. Nature of study was descriptive, non- contrived, cross sectional and quantitative. Universal sampling technique was exploited to collect data from all students of department of education, university of Gujrat, Pakistan. An adopted questionnaire was used to measure anxiety level of students against thirty statements. Mean , Standard Deviation and Pearson correlation were run for data analysis. No relationship between examination anxiety and academic achievement was found among university students. It was explicated that examination anxiety is not caused of low, average and high achievement of the student.

Technologies have advanced rapidly in the field of digital signal processing due to advances made in high speed, low cost digital integrated chips. These technologies have further stimulated ever increasing use of signal representation in digital form for purposes of transmission, measurement, control and storage. Design of digital filters especially adaptive or semi adaptive is the necessity of the hour for SAR applications. In this research work Butter worth digital FIR semi adaptive band pass filter for 700-800 KHz for 128 order Kaiser window with 0.5 Beta was designed using XILINX and MATLAB soft wares. As part of practical research work 700 -800 KHz Butter worth digital FIR semi adaptive band pass filter for 700-800KHz for 128 order Kaiser window with 0.5 Beta was designed using FPGA kit using SPARTAN-3E. These were optimized, analyzed, compared and evaluated keeping the sampling frequency at 5 GHz. Both these filters were tested by passing a sinusoidal test signal of 781 KHz along with noise and the filtered output signals are presented.

Pure and divalent metal ion Mg 2+ doped Copper sulphate and Potassium Dichromate crystals have been grown from aqueous solution by slow evaporation technique. The pure copper sulphate and pure potassium dichromate crystals were noted as CUS and KDC. Powder X-ray diffraction studies confirmed the phase formation and magnesium ions doping into KAP crystals. The presence of functional groups in the crystal has been observed by FTIR analysis. Optical transmission studies were carried out by allowing the UV-Vis ray of wavelength between 200 and 1100 nm was pass through the (010) face of the grown crystals. The optical transmission studies reveal that the pure and magnesium ion doped copper sulphate crystals were better transmission in the wave length region of 350 nm to 550 nm. In the case of pure and doped potassium dichromate crystals transmission was better in the wavelength region of 550 nm to 1100 nm. Optical transmission is found to be decreases in pure and magnesium ion doped copper sulphate crystals from 550 nm to 800 nm and above 800 nm it was increases up to 1100 nm.SHG efficiency of all these crystals were not active. The grown crystals were also subjected to FTIR and microhardness studies.

The study was conducted to assess dairy production and marketing system of Horro district of Horro Guduru Wollega zone. A structured questionnaire was used and the study area was stratified into highland and Mid-highland agro-ecology. The means and standard deviations of livestock holding was found 12.17±8.69, 13.54±13.98, 3.22±5.25, 2.79±2.84 and 0.96±1.34 for cattle, sheep, goats, horse and donkey, respectively. Cattle herd structure is governed by the overall function of the animal in agricultural production system; however, this study revealed that the proportion of male to female cattle was in-balance (49.5:50.5%) in the total herd studied. The overall means and SDs of milking cow holding was 2.14 ± 1.57 where it was higher for the highland than mid-highland smallholders agro-ecology. Cows’ average lactation length was 8.16 months and estimated total lactation milk yield within this lactation period was not more than 360 liters/cow. The major livestock input supply and service delivery expenditure was mainly for veterinary services where animal feed purchase, labour employment and renting grazing land during summer seasons were also another challenges which farmers in the study area were encountering. Udder washing before and after milking was rarely practiced where about 74.23 percent producers do not wash udder before milking and only 25.27 respondents wash udder before milking. However, ‘Lantana trifolia, Sida cuneifolia and Cucumis prophetarum’ were the most commonly used plant/herbs for cleaning and washing milking and milk storing equipments in the study area. The means and SD of shelf life of butter in days was studied and butter can be kept un-perished for up to 159.45(84.915) and 68.44(42.416) at highland and Mid-altitude. The difference in butter shelf life was highly significant at (P>0.001) among the highland and mid-highland. The difference in shelf life of yogurt was also significantly (P>0.001) higher for mid-highland than highland.

In the present global scenario, today’s learners’ of science and technology need to develop an array of skills to achieve their full potential and navigate smoothly through a wide range of professional situations. The traditional educational approach of specializing in the specific subject is no longer considered adequate in the present global society. They need to develop the qualities such as understanding self and others, empathy, effective communication and social values, to create harmonious environment in the organization and society at large. A dire need is felt to broaden the vision of educational objectives to bridge the deep divide between the world of work and world of learning. Hence it is imperative to incorporate the life skills which influence the behavioural traits of the learners and facilitate in developing the individual as a holistic personality and improve their potentials in various dimensions.

ABSTRACT The use of the laser in its relationship to dentistry is a new tool. Surgical lasers have been used in medicine for over a decade in the surgical specialties of Otolaryngology, dermatology, plastic surgery, gynecology, ophthalmology, neurosurgery, urology, thoracic and cardiovascular surgery, gastrointestinal surgery, orthopaedics and most recently in oral and maxillofacial surgery. Recently lasers have been recommended as an alternative or adjunctive therapy in the control and treatment of periodontally diseased root surface. Lasers commonly used in dentistry are CO2, Nd:YAG, Ho:YAG, Er: YAG, Er,Cr:YSGG, Nd:YAP, GaAs (diode) and argon .The present article aims at providing an overview of basic principles and various types of lasers used in periodontal therapy.
