Impact of Salinity Stress During Germination Stage on Chickpea (Cicer arietinum L)
Journal ArticleThe salinity of irrigation water is a serious problem facing crop plants in the Mediterranean region, where plants are exposed to high temperatures and severe shortage of water in the dry season. So, this study was carried out in order to test the effects of five different salinity levels of sodium chloride (0.0, 50, 100, 150, 200 and 300 mM) on seed germination and early seedling growth of Chickpea (Cicer arietinum L.). Fifty homogenous and cleaned seeds were germinated in Petri dishes inthree replicates. The salt stress decreased seed germination, the response of Chickpea (Cicer arietinum L.) to salt stress and water stress was evaluated at the germination stage. The severe reduction in germination percentage and particularly germination speed with prolonged lag period by moderate salinity level at 100 mM NaCl, suggests that Chickpea (Cicer arietinum L.) is a salt-sensitive species during germination. Salinity reduced germination uniformity and germination synchrony and might delay start of germination but accelerates its termination with a consequent shortening of the time spread of germination. The recovery percentage was lo wer but speed of recovery was higher compared with the corresponding parameters of the control seeds. Recovery percentage was slightly improved with increasing in the concentration of NaCl.

Effect of Medical Plants on Digestive Enzymes and Growth Performance of rainbow trout (Oncorhynchus mykiss)
Journal ArticleAbstract: This study was designed to evaluate the growth and digestive enzyme activity parameters of rainbow trout juvenile Oncorhynchus mykiss fed diets containing different levels (0%, 0.1%, 0.5% or 1%) of Glycyrrhiza glabra, Coriandrum sativum and Cassia angustifolia aqueous methanolic extract as a feed additive seventy-five days. The fish with initial weight of 22.65 ± 0.07 g were divided into 30 tanks so that 10 groups would be formed and stored as 50 fish in each tank, so the experiment was started as three replications. At the end of every month, samples are collected from the digestive system for use in measuring digestive enzymes, and scales and weights for use in measuring growth rate. Digestive enzymes like pepsin, trypsin, amylase and lipase and growth parameters such as final weight, weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR). Amylase, lipase, pepsin and trypsin are different in terms of enzyme activities. The effect of medicinal plants gave a good indication of improvement in the effectiveness of digestive enzymes with the length of the experiment during the surrounding environment. The values related to the growth parameters were lower than the control group in the study where similar or low values were encountered.

Hyperglycaemia‑Induced Contractile Dysfunction and Apoptosis in Cardiomyocyte‑Like Pulsatile Cells Derived from Mouse Embryonic Stem Cells
Journal ArticleAbstract
Hyperglycaemia, a key metabolic abnormality in diabetes mellitus, is implicated in pathological cardiogenesis during embryological development. However, the underlying mechanisms and potential therapeutic targets remain unknown. We, therefore, studied the effect of hyperglycaemia on mouse embryonic stem cell (mESC) cardiac differentiation. The mESCs were differentiated via embryoid body (EB) formation and cultured under conditions with baseline (25 mM) or high (50 mM) glucose. Time-lapse microscopy images of pulsatile mESCs and Ca2+ntransients were recorded. Biomarkers of cellular changes were detected using immunocytochemistry, terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) assay, and Western blot analyses. Differentiated, spontaneously beating mESCs stained positive for cardiac troponin T, α-actinin 2,nmyosin heavy chain, and connexin 43. Hyperglycaemia decreased the EB diameter and number of beating EBs as well asnthe cellular amplitude of contraction, the Ca2+ transient, and the contractile response to caffeine (1 mM), but had no effect. on the expression of the sarco-endoplasmic reticulum calcium transport ATPase 2 (SERCA 2). Furthermore, hyperglycaemia decreased the expression of B cell lymphoma 2 (Bcl-2) and increased the expression of cytoplasmic cytochrome c and the number of TUNEL-positive cells, but had no effect on the expression of one of the mitochondrial fusion regulatory proteins, optic atrophy protein 1 (OPA1). Overall, hyperglycaemia suppressed the mESC cardiomyocyte-like differentiation and induced contractile dysfunction. The results are consistent with mechanisms involving abnormal Ca2+ handling and mitochondrial-dependent apoptosis, factors which represent potential therapeutic targets in developmental diabetic cardiac disease.

Barrier height nature and photovoltaic properties of (2-(2-(2-nitrophenyl)diazenyl)malononitrile)/p-Si heterojunction
Journal ArticleSmall molecule, (2-(2-(2-nitrophenyl)diazenyl)malononitrile) (NPDAM), is synthesized and its chemical structure is characterized by different analyses. NPDAM powder is identified as polycrystalline monoclinic structure, whereas the thermally deposited films have nanostructure character with average particle size of 39 nm. NPDAM films are utilized for manufacturing hybrid solar cells in the structure of Au/NPDAM/p-Si/Al. The dark current-voltage (I-V) curves of the diode are measured in the temperature range 303-383 K and the thermionic emission theory is employed to extract the ideality factor, n, and potential barrier height, ∅ at forward applied voltages of V≤0.20 volt. The n value increases, whereas the ∅ value decreases with decreasing temperature. This behavior is analyzed in terms of the lateral inhomogeneous barrier following Gaussian distribution at the NPDAM/p-Si interface. Cheung and Cheung functions are used for extracting the values of series resistance, Rs, n and ∅. The behavior of these parameters as a function of temperature is discussed. At forward applied voltages 0.20<V≤2, the I-V relation reveals crossover from thermionic emission to square power law. This behavior is discussed by means of the space charge limited current. Under illumination, the device exhibits a response to light exposure with a photoelectrical conversion efficiency of 2.91 %.

Hydrogeochemistry of groundwater aquifers in Azintan, Northwestern Libya
Journal ArticleThe groundwater aquifers in Azintan, northwestern Libya suffer from an acute shortage of water. The groundwater was evaluated to determine its suitability for drinking and irrigation purposes from major two aquifers in north and south of Azintan area. This study carried out to assess the groundwater quality and to identify major affecting variables. Twelve samples from the two aquifers were collected. The two aquifers were collected and analyzed for total dissolved solid (TDS), electrical conductivity (EC), pH, Ca2+, Mg2+, Na+, K+, Cl-, SO42-, CO32- and HCO3-. The results show that, the groundwater in many places is dominated by higher concentrations of Cl-, SO42- and HCO3-. Two water types were recognized in this region are Cl-SO4-Na-Ca and Cl-SO4-Na. Gibbs and Piper method, as well as the hardness, soluble sodium percentage and the permeability index all have been used to assess the diagram quality of the groundwater of aquifers. Further, the multiple correlations and Cluster Analysis of groundwater quality parameters were carried out for further classification and interpretation of the groundwater quality. Finally, water qualities in the study area are compared with Libyan standards and WHO guidelines of drinking water and irrigation purposes.

Earnings Management and Accounting Reporting Fraud: A Theoretical Comparative Approach
Journal ArticleThe term of earnings management is sometimes used in literature as a synonym for accounting reporting fraud. Thereby, this paper aims to review the existing literature to offer a better clarification to the primary characteristics and differentiation between earnings management and accounting reporting fraud. The results of other previous studies have been reviewed to demonstrate the results of this study using a number of alternatives available resources to the collection of the relevant literature. The findings demonstrate that the activities of manipulating financial information continue to prevail in the business environment worldwide, despite the fact that there are strict laws and regulations to prevent earnings management and fraud behaviour. Therefore, defining the motivation of managers manipulative behaviour can enable academics and regulators to establish a framework to distance between earnings management and fraud and to recognize fraudulent actions through attempting to pursue how managers act to achieve their objectives.

The etiology of infertility in the western region of Libya: an investigation of medical records
Journal ArticleAim:
The aim of this study is to investigate the etiology of infertility in couples seeking medical help from the Infertility Clinics and gynecological departments in hospitals in Western Libya.
Patients and Methods:
Data were collected directly from patients' medical records. However, additional data were collected through interviews.
Results:
The total number of couples recruited was 135. Men (mean±standard deviation of age= 41.7±7.0 years) were significantly older than women (35.2±6.5 years)(P= 0.001). Women were more likely to marry younger than men (mean difference= 6.5 years, 95% confidence interval [CI]= 5.1–7.8 years) and the duration of all participant's marriages before the interviews was 9.0±5.0 years. The causes of fertility were as follows: 33 (24.4%)(95% CI 17.16–31.64) cases were due to a female factor, 92 (68.1%)(95% CI= 60.24–75.96) cases were due to a male factor with 6 (4.4%)(95% CI 0.94–7
