Abstract... The contents of B1,B2 and B9 were estimated in some vegetable samples including: (Cabbage, Beets, Cauliflower and Lettuce) by HPLC technique. The concentration-swere measured from the calibration cueve also the validation methods were calculated. The evaluation of calibration model was based on the coefficient of determination (R2).The linearity of the concentrations was studied according to values of slope and intercept of the regression line and the correlation coefficient (R2).The fruitful linearity was obtained for the compounds between the concentrations and peak area , where the concentration which gave good linearity were ranged as following: 25 – 200 μg/ml ,5 – 25 μg/ml and 100 – 400 μg/ml for B1 , B2 and B9 , respectively.
Abstract... Novel derivatives of 2-isoxazoline oxime and 5-hydroxy-2-isoxazoline derivatives were synthesized by the oximation reaction of benzylidenacetylacetone and its derivatives with hydroxylamine hydrochloride using two methods. Benzylidenacetyl-acetone was introduced to oximation reaction under strong basic conditions to produce a trans-isomer of 2-isoxazoline oxime with 64% yield. In contrast, the oximation reactions of 2-nitro, 4-methoxybenzylideneacetylacetone derivatives under milder conditions gave various heterocyclic compounds depending on the nature and position of the substituent. The reaction of 2 nitrobenzylidenacetylacetone led to the synthesis of Z and E-isomers of 5-hydroxy-2-isoxazoline derivative with Z/E ratio equal 1:1, and the reaction of 4-methoxybenzylidenacetylacetone gave also Z-and E- 5-hydroxy-2-isoxazoline derivative but the ratio was 1:2 of Z/E isomers.

Abstract... This paper deals with the use of murexide indicator as a ligand for spectral estimation
of Mn (II). The effect of using different ratios of (2-propanol: water) mixtures on the absorption spectrum of murexide as well as its complexes with the studied metal ion was investigated. The effect of some factors affecting the stability of these complexes, such as time and pH, were studied at different solvent ratios: (2: 8), (4: 6), and (3:7) of 2-propanol and water, respectively. The stoichiometry, stability constant and
molar absorptivity were estimated using the method of continuous variations of the murexide complexes with Mn (II) at the ratio (3: 7) and the results were as follows: 1:2, 1X1013, 7322 L.mol-1.cm-1, respectively, while these complexes were not stable enough to be studied in the other ratios. The spectral method for estimating this ion was evaluated at the ratio (3:7), by estimating the sensitivity, detection limits, quantification
limits, and the linear range of the Pierre - Lambert law, where the obtained results were: 0.160 ppm-1, 0.0290 ppm, 0.0966 ppm, 0.2-3.5 ppm, respectively. The effect of increasing the concentration of ions on the reliability of the proposed spectroscopic method was also studied, and it was found that the degree of reliability decreases at high concentrations of these ions.

Abstract... Dates are highly nutritious, although there is a decline in their consumption rate. This study was conducted on four types of local dates collected
from the popular market in the city of Misurata, which are Ami, Taboni, Bakrari and Marwani dates. These varieties were chosen for their high
consumption. The main nutritional components of the samples were studied after removing the cores (moisture, ash, carbohydrates, protein, fats and fibers), as well as their mineral content (sodium, potassium, calcium and magnesium). The results of this study showed that the highest percentage of carbohydrates, fats and protein was In the Al-Bakrari date sample, while the
highest percentage of fiber was in the Al-Marwani sample, as for the results of mineral elements, the Al-Bakrari date sample recorded the highest concentration of sodium and calcium, while the highest concentration of potassium and magnesium was in Al-Ami dates sample.

Abstract... In this work, I investigated the digenean parasites of marine fish, Alepes melanoptera, in the Malaysian Sea coast for the first time. Fishes were collected throughout a five months period from local fishermen in Terengganu. A total of 325 fish specimens were subsequently examined for parasites using conventional methods under a dissecting microscope. The examination included gills, pharynx, body cavity and visceral organs (stomach, intestine, liver, swim bladder and gonads). Worms recovered
were fixed and preserved using methods commonly applied. A total of one species
belonging to the genus Pseudopecoeloides Yamaguti, 1940 was identified. Morphological
description of Pseudopecoeloides tenuis Yamaguti, 1940 was provided, together with it's prevalence and mean intensity. The calculated overall infection prevalence (%) and mean intensity values were 0.30 % and 1, respectively. This data is the first on the digenean parasite fauna of A. melanoptera collected from the Malaysian coastal waters of the South China Sea. P. tenuis Yamaguti, 1940 is new parasite record for Malaysia.

E. guaza, 30% in E. aeneus, 20% in E. castae 17.5% in S. scrofa and 12.5% in M.mastelus, but the infection rate in small fish was 15.5%.
Abstract... Survival analysis is a branch of statistics, which is focused on the analysis of time-toevent
data. A primary focus of Survival analysis in medicine is modeling time to surviving a particular disease. In this paper, survival analysis was carried out on Chronic Granulomatous Disease (CGD) data modeling time to surviving the disease. The Kaplan-Meier approach was used to describe the survival functions of (CGD)
patients and Log-rank tests were used to compare the survival curves among groups.
Different kinds of models such as Cox Proportional Hazard Model and Accelerated
Failure Time (AFT) models like the Weibull AFT model to be used for modeling the time to surviving from (CGD). Models selection criteria were used as a guide to unravel the best model for modeling (CGD).
Abstract... One of the important statistical methods used in statistics is the nonparametric methods that are concerned with analyzing data that do not follow a normal distribution, as these methods deal with a study of the community without the need to know its probability distribution, and many tests are included in it, where this paper touched on the study of two types of them only, namely (Kruskal-Wallis, Cochran).
From this point of view and as a practical application of these two analyzes, a field
study was conducted on a random sample of newborn mothers, by distributing 50 forms in order to reach the most important factors affecting the weights of newborns in the city of Misurata, where the results of the study showed that through the Kruskal- Wallis test ) It was found that the factors, the level of nutrition of the pregnant mother and her high blood pressure, had a significant effect on the weight of the
newborn, and the results of the (Cochran) test showed that the factors blood sugar level of the pregnant mother and the type of birth had a significant effect on the weight of the newborn
