Job Satisfaction of the Teachers of the First Three Grades in the Schools Under the Supervision of First Zarqa Directorate of Education from Their Perspective

The present study aimed to explore the job satisfaction level of the teachers of the first three grades in the schools under the supervision of First Zarqa Directorate of Education from their perspective. The sample consists from 177 teachers. This study was conducted during the academic year (2017/2018). Those teachers were selected through using the simple random sampling method. They were selected from the schools under the supervision of First Zarqa Directorate of Education in Jordan. A questionnaire was used for data collection. The validity and reliability of the questionnaire were measured. It was found that the job satisfaction level of the teachers of the first three grades in the schools under the supervision of First Zarqa Directorate of Education is moderate. It was found that there isn’t any statistically significant difference - at the statistical significance level of (α ≥0.05)- between the respondents’ job satisfaction levels which can be attributed to (gender, academic achievement and experience). It was found that there is a statistically significant correlation between job satisfaction from one hand and (work environment, teachers’ relationships with the administration, moral and financial incentives & teachers’ relationships with colleagues and society members) from another hand. The researcher recommends improving the physical work environment of the teachers of the first three grades. That shall raise the job satisfaction level of those teachers.

A new approach for achievement of inulin accumulation in suspension cultures of Jerusalem artichoke (Helianthus tuberosus) using biotic elicitors

AbstractA promising protocol for achievement the accumulation rate of inulin compound in a suspension culture of Jerusalem artichoke (Helianthus tuberosus) was established. The effect of incorporated of cell cultures in combining with two type of biotic elicitors Aspergillus niger extract and Methyl-Jasmonate incorporation feeding medium on leaf cell growth patterns and production of inulin was investigated. The maximum value of cell growth parameters and highest content of inulinase activity (0.395u/ml) were resulted from elicitation of augmented MS-medium with A. niger extract at the level of 0.2% in combination with Methyl-Jasmonate (150μM) as compared with other concentrations after 2weeks of cultivation. The chemical analyses of the different cell lines were spectro-photometerically performed. This study clearly indicates that combining of A. niger and Methyl-Jasmonate elicitors plays a critical role on inulin process and its accumulation in Jerusalem artichoke cell cultures

Para-Veterinarians in Egypt

Para-veterinarians are professionals in having a liaise between veterinary doctors and livestock owners beside their ability to achieve some of the veterinarians activity such as Collecting information about sick animals, using thermometer, using needles and syringes, Calculating, diluting and using antiseptic, knowledge about live and inactive vaccines, oral treatment of animals, herbal medicine, rectal palpation for detection of pregnancy, hoof treatment, treatment of chronic inflammation by using old methods such as blister and intervention in some large surgical operations such as abomasal displacement. According to our knowledge, This is the first review that highlight on the role of para-veterinarians in the Egypt as a co-aid for veterinary doctors

Postharvest application with propolis for controlling white rot disease of green bean pods

White rot is the most severe disease attacking green bean pods during pre and postharvest stages. Ethanol extracted propolis (EEP) at four concentrations i.e. 0, 5, 10 and 15% was tested to study its effect on growth inhibition zone of the causative fungus Sclerotinia sclerotiorum. Results indicated that all tested concentrations of EEP significantly increased the inhibition zone of S. sclerotiorum growth. The highest increase was obtained with at 15% where complete reduction in sclerotia germination occurred. At EEP 10%, the sclerotia germination was reduced by 91.6%.  When the same concentrations were tested to study their effect on white rot disease of green bean pods during storage, all EEP significantly reduced the percentage of white rot incidence and severity. The highest reduction was obtained with EEP at 15%; reducing the disease incidence and severity by 90 and 91.8% respectively, followed by EEP at 10% which reduced the incidence and severity by 78 and 82% respectively. EEP at 5% showed moderate effect. EEP is suggested as good biosystem within integrated management of pathogens and safe alternative for controlling postharvest diseases of green bean pods

Using Decentralized Aggregation for Federated Learning with Differential Privacy

Nowadays, the ubiquitous usage of mobile devices and networks have raised concerns about the loss of control over personal data and research advance towards the trade-off between privacy and utility in scenarios that combine exchange communications, big databases and distributed and collaborative (P2P) Machine Learning techniques. On the other hand, although Federated Learning (FL) provides some level of privacy by retaining the data at the local node, which executes a local training to enrich a global model, this scenario is still susceptible to privacy breaches as membership inference attacks. To provide a stronger level of privacy, this research deploys an experimental environment for FL with Differential Privacy (DP) using benchmark datasets. The obtained results show that the election of parameters and techniques of DP is central in the aforementioned trade-off between privacy and utility by means of a classification example

Influence of low grade exercise on skeletal scintigraphy using Tc-99m methylene diphosphonate

BACKGROUND: Tc-99m methylene diphosphonate [MDP] bone scan is the basis of the skeletal imaging in nuclear medicine being a highly sensitive tool for detecting bone diseases. Mechanical stimulation induced by low grade exercise or whole-body vibration appears to be advantageous regarding the maintenance and/or improvement of skeletal mass in humans. We aimed to assess the physiological influence of low grade exercise on the quality of skeletal scintigraphy using Tc-99m MDP. MATERIAL AND METHODS: Tc-99m MDP bone scan was done for 92 volunteers [Group 1; G1]. Five days later, the same subjects were re-scanned [Group 2; G2] after an exercise on treadmill for 5 minutes. Image quality was assessed using quantitative measures whereby equal regions of interest (ROI) were drawn over the femoral diaphysis, and the contralateral adductor area. The total number of counts from the bone [B] ROI and soft tissue [ST] ROI was expressed as a ratio [B:ST ratio] and a mean value for each was established. RESULTS: Statistically significant difference was found between the B:ST ratio means [p = 0.001] in G1 and G2. CONCLUSION: This study raised a physiological influence of low grade exercise on the image quality of tc-99m MDP skeletal scintigraphy by increasing MDP osseous uptake

Studies on the quality of sugar, molasses and treacle as products of sugarcane in the Sudan

2003Comprehensive physio-chemical analysis were carried out for products of sugar cane in an attempt to find the effect of extraction and refining on the quality of sugar, molasses and treacle (black honey). The study analysis were conducted on three grades of refined sugar, namely silver-sugar, green-sugar and normal-sugar in addition to treacle, molasses samples and cane syrup, massecuite at different stages of crystallization. The samples were obtained mainly from Kenana Sugar Factory, where complete refining is done, specially decolourization. The analysis included determination of sucrose, reducing sugars, invert sugars, total soluble solids (T.S.S), and sweetness in terms of purity. Ash, acidity and protein content. Similarly physical properties were measured mainly: viscosity, colour and particle size of sugar crystals. The results obtained revealed that the average percentage of sucrose of treacle (black honey) was 29.36%, molasses 32.56%, whereas it was 99.90%, 99.81%, 99.76% for silver-sugar, green-sugar and normal-sugar respectively. The reducing sugars were 50.26% for treacle and 16.88% for molasses and only 0.036%, 0.060% and 0.189% for silver-sugar, green-sugar and normal-sugar. The moisture content was 20.50% for treacle and 21.30% for molasses. However, that for refined sugar did not exceed 0.047%. Slight traces of ash were found in sugar samples. While molasses gave 12% ash as yet it was poor in nitrogen consequently in protein content. The total soluble solids were found to be 99.98%, 99.97% and 99.95% in the silver-sugar, green-sugar and normal-sugar respectively. while treacle gave 83.24% and molasses 86.98%. T.S.S. Sweetness estimated as purity was found in the range 99.81% to 99.92% for the refined sugar samples and only 37.43% for final molasses. Sugar solutions were found to be almost neutral with pH 6.5 but molasses and treacle were slightly acidic 5.6%. The viscosity was calculated at 30ºC and found to be 3.426 centistoke for treacle and 5.019 centistoke for molasses. The three refined sugar samples silver, green and normal - sugar gave 1.940, 1.942 and 1.945 centistok respectively. The mean aperture of sugar crystals was 0.54mm for silver-sugar, 0.63mm for green-sugar and 0.68mm for normal-sugar. The colour of the sugar was measured colourimetcally and was found to be 41 unt at l 420nm for silver-sugar whereas green-sugar and normal-sugar gave 129 and 519 unt. respectively. Chromatographic analysis using TLC technique revealed consistency with chemical analysis findings for sugar, treacle and molasses components of mono-and di-saccharides, namely glucose, fructose and sucroseUOF

Activating the role of judicial oversight in Iraq to reduce the phenomenon of tax evasion Field research in the Federal Office of Financial Supervision

Purpose: Security measures have become increasingly important due to the expansion of the cyber environments. National and international entities are exposing themselves to cybersecurity risks, and they are growing in number every day.   Theoretical Framework: With a comprehensive cybersecurity plan, threats can be eliminated. Implementing this plan is possible by involving all stakeholders in the management processes because the idea of management is insufficient. To ensure cybersecurity, this study highlights the significance of cybersecurity and cybergovernance in the digital world.   Design: The study findings and recommendations for cybersecurity governance were reviewed. A scoping review research model was used for this purpose.   Findings:A basic and documentary research model related to research philosophy were developed for the application technique. The scope of the research includes publications from Scopus. Studies from the last ten years were downloaded using the selected keywords.   Originality: The results show that despite research that has led to local cybersecurity governance solutions in several countries, a comprehensive governance framework has not yet been established. Instead, there is a hidden conflict over control of this region, not its governance.”
