This study examined effect of potassium drip fertigation on the growth and

fruit yield of tomato under field conditions at western Libyan conditions, in two

consecutive seasons. The soil texture sites was sandy, pH around 8.0. the soil potassium

was extracted and estimated by flam photometer at 766 μm. The rate of potassium fertilizer

were F1: 0; F2: 150; F3: 300 kg K2O ha-1 as potassium chloride form in three replicates.

The experimental site was designed in randomized complete block (RCBD). and I1: 75%

ET𝑐; I2: 100% ET𝑐; I3: 125% ET𝑐 levels for irrigation. The interactions for both potassium

fertilization levels and irrigation treatments with fruit yield were found. The single

treatments of potassium fertilization or irrigation significantly affected the tomato fruit

yield, where fertilization and irrigation applications increased the fruit weight from 13.99 t

ha-1 to 34.47 t ha-1 t/ha minimum in F1I1 and maximum in F3I3. Application of different Kfertilizers

and irrigations had significant effect in PFP (partial factor productivity), and

AUE (agronomic use efficiency) as compared to K-control plots of tomato. The average of

PFP for K and irrigation in two treatments were 65.65 kg kg-1 in F2I3, and 59.43 kg kg-1 in

F3I3 which are greater than the values of control, F1I1, F1I2, and F1I3 treatments

ABSTRACT Coronary artery disease (CAD) is quite common among diabetics in all age groups and its risk is independently affiliated with Lipoprotein-associated phospholipase A2 (LP-PLA2). There is strong evidence that the elevated plasma level of Lp-PLA2 indicates vascular inflammation associated with plaque formation within the arteries. Therefore, the relationship between the plasma Lp-PLA2 level and coronary

artery disease risk factors between non-diabetic and diabetic patients will be studied. Materials and Methods: A total of 181 individuals were recruited from the National Heart Centre Tajoura and divided into 4 groups (40 healthy controls (HC), 43 non-diabetics (NDM) who had CAD, 54 DM2 without CAD, and 44 DM2 who had CAD). The relationship between Lp-PLA2 and the potential biochemical risk markers for CAD will be studied between the groups. Results: All the groups that participated in this study have similar body mass index. There is statistical significance in the level of plasma level Lp-PLA2 between DM2 with CAD, DM2 without CAD and HC with ( ***P<0.0001, **P<0.006), respectively; and likewise between NDM with CAD and HC with *P<0.05. Although there is a significant difference between the plasma levels of Lp-PLA2 between the groups below the age of 60 years, there is no statistical significance between the groups above the age of 60 years. Correspondingly, there is a statistical difference in the plasma level of Lp-PLA2 between healthy controls and both DM2 without CAD and DM2 with CAD with (**P<0.006, and ***P<0.0001), respectively. Once more, there is statistical significance in the plasma level of Lp-PLA2 between NDM with CAD and healthy controls with *P<0.05. Furthermore, there is a statistical difference in the serum level of CRP between DM2 with CAD and HC. In addition, there is a positive relationship exists between the duration of diabetes mellitus without CAD and the level of glycated haemoglobin (HbA1c) with **P <0.003 in both genders. Conclusion: In this study, the high level of Lp-PLA2 and CRP strongly indicate the presence of vascular inflammation associated with the formation of arterial atherosclerosis with thrombus formation. These findings are also correlated with diabetic duration and they could be used in the diagnosis and prognosis of coronary artery disease. 

Abstract— Ninety-four rock samples were taken from the Middle to Late Devonian Awaynat Wanin, Early Carboniferous Marar, Late Carboniferous Assedjefar formations. The cuttings of Assedjefar Marar and Awaynat Wanin Formations collected from two wells, in the A1-163 oil field, locateed in the Murzuq Basin. RockEval Pyrolysis, Total Organic Carbon (TOC) and molecular biomarker (via the use of chromatographymass spectrometry, GC-MS) as geochemical parameters were applied to find out the types of kerogen, depositional conditions and level of organic matter maturity for representative samples. Such Formations are poor to excellent quantity of organic matter. Results of TOC related with remaining generation potential (S2) and hydrogen index (HI) data showed that the organic matter attributed to Type II/III and Type III kerogen (gas and oilprone organic matter), as well connected to S1 parameter indicated indigenous hydrocarbon exist. Ratios data of individual hydrocarbons, n-alkanes, isoprenoids and biomarkers parameters of Triterpanes and steranes indicate non-marine with marine organic matter deposited under non-marine conditions for Awaynat Wanin samples while Marar and Assedjiefar Formations deposited in nonmarine to deltaic conditions. The maturity data from Tmax, spore colour index and biomarker related parameters based on terpanes, steranes, and low molecular-weight hydrocarbons indicate the studied rocks are ranged from immature to mature.

Key Words— Awaynat Wanin Formation, Middle to Late Devonian, Kerogen, Biomarker, Rock Eval, Murzuq Basin

The experiment was conducted to assess the sensitivity of potato yield to dif-ferent irrigation levels at different growth stages. Irrigation levels were determined as percentages (WI 100% as readily available water to the crop (RAW)), and for the rest of the treatments (WII 75%, WIII 50%), as they were applied separately to all four stages of crop growth i.e., vegetative (SI), tuber initiation (SII), tuber bulking SIII, and tuber matu-ration (SIV). The design of complete random sectors was adopted to perform the experi-ments. The results revealed that all the studied parameters: plant height (cm), vegetation plant weight (g), number of tubers per plant, tuber weight (g), tuber yield (ton/ha), and crop water productivity (kg/m3) varied among irrigation water levels at different stages of growth. It was found that the two stages, SII and SIII in potato crops, were more sensitive to deficit irrigation compared to other stages. According to the obtained results, in the case of water abundance conditions, the treatment WII SI can be applied to obtain the highest water crop productivity. In conditions of water scarcity, it becomes necessary to apply the treatment WIII SIII to obtain the highest crop water productivity.

The identification and classification of reservoir hosts of zoonotic cutaneous leishmaniasis are very crucial towards the integrated management and control planning. Molecular techniques have been deployed and showed very sensitive and specific results to identify and differentiate rodents with great similarity in phenotypes including Meriones spp. Meriones species are very difficult to distinguish and separate according to their morphology and phenotype traits. This study was carried out in western region of Libya and three Meriones rodents were collected and their genetic identification was conducted by PCR technique using designed forward and reverse primers from Meriones spp. cytochrome b (cytb) gene sequence. This study has differentiated three haplotypes of M. shawi. with sequences similarities between samples of haplotypes were 99.13%, 99.42% and 99.71% between H1 and H2, between H1 and H3 and between H2 and H3 respectively. The current work is the first to use molecular techniques to study the genetic sequence of Meriones in Libya and has illustrated that PCR technique is powerful tool to discriminate Meriones species

Understanding the interactions among soil properties,

salinity and the inorganic substances application is

great importance for improving growth of Coriander [Coriandrum sativum L.] in sandy soils. In the present

study, twenty seeds of Coriander were sown during the growing season 2016 to investigate the effe ct of some

inorganic substances [Bentonite, Nano selenium and Micronutrients mixture] on Coriander growth and

properties of sandy soil under salinity condition. A split plot design replicated thrice was used in this study.

The results indicated significa nt succeed in enhancing all estimated soil properties, such as available

nutrients in soil, EC, pH and bulk density. Besides, traits of coriander plant i.e., plant height, fresh, dry weights

and plant chemical composition. Therefore, it could be recommende d that adding of inorganic substances can

improve the sandy soil properties and growth parameters of coriander plant
