    Many education organizations have adopted for security the enterprise best practices for implementation on their campuses, while others focus on ISO Standard (or/and) the National Institution of Standards and Technology. All these adoptions are dependent on IT personal and their experiences or knowledge of the standard. On top of this is the size of the education organizations. The larger the population in an education organization, the more the problem of information and security become very clear. Thus, they have been obliged to comply with information security issues and adopt the national or international standard. The case is quite different when the population size of the education organization is smaller. In such education organizations, they use social security numbers as student ID, and issue administrative rights to faculty and lab managers – or they are not aware of the Family Educational Rights and Privacy Act (FERPA) – and release some personal information. The problem of education organization security is widely open and depends on the IT staff and their information security knowledge in addition to the education culture (education, scholarships and services) has very special characteristics other than an enterprise or comparative organization This paper is part of a research to develop an “Education Organization Baseline Control Protection and Trusted Level Security.” The research has three parts: Adopting (standards), Testing and Modifying (if needed). The baseline control criteria covers the following topics: management control, operational control, logic control, physical control and development and maintenance control. This paper is concerned with the first two controls

    Strongyloides stercoralis is a nematode parasite which causes a protracted asymptomatic intestinal infection. It is considered a life threatening condition in immunocompromised patients when hyperinfection is associated with disseminated disease. The diagnosis by routine stool examination is very limited since the larval output in stools is very low. We present the case of a 52 year-old Omani man from Salalah, in the southern region of Oman, with a 15-year history of type 2 diabetes mellitus and recently discovered to have hairy cell leukaemia, who complained of nausea, abdominal pain, loss of appetite and loss of weight. An oesophagogastroduodoscopic biopsy was obtained and histopathologic examination revealed gastrointestinal strongyloidiasis.

    This study investigates the fungal biodiversity of water and sediment samples from some waterbodies and their ability to degrade Methyl orange (M.O.) on a solid medium. Ten fungal genera were isolated, and the genus Aspergillus represented the highest percentage (70%). Sixteen fungal species were isolated that 88% of which (14 species) belonged to anamorphic fungi. Trichoderma sp. showed the highest percentage (40%). Out of the 16 isolated fungi, Aspergillus flavus, A. niger, and A. terreus showed the best result for decolourising M.O. on a solid medium potato dextrose agar. These fungi isolates were selected to test their ability to biodegrade M.O. in a liquid medium supplemented with 50 mg.L-1 M.O. as the sole carbon source. Based on the results, after 7 days of incubation, A. niger degraded 14% of M.O., while A. flavus and A. terreus degraded 12% of the dye

    This study was carried out at the General Al-Mohmmodia Hospital/ Al-Mohmmodia district/ Baghdad/Iraq. Ginger rhizome (Zingiber officinale) has become a subject of interest due to its bioactive contents such as an antioxidant and androgenic affect in diseases treatment in more countries world-wide. As an antioxidants ginger has an effective role on spermatogenesis and blood biochemical parameters. Thirty women almost of them suffering from high blood lipid profile and cholesterol, some of them had kidney dysfunction were taken. All women were conducted to explore the consumption of about 1gm daily for complete month on the physiological performance, lipid profile, kidney function and testosterone and progesterone hormones. The result of BMI showed significant difference of all ages groups and for all the kind of overweight and obesity. However Hb level showed a significant differences (p<0.05) between different ages, Hb showed no significant differences within the same age before and after consumption the ginger powder (p˃0.05). Blood glucose was not differ significantly between the group ages, but it was significantly (p<0.05) difference before and after the ginger powder consumption. Serum cholesterol, total glyceride. LDL, HDL, and VLDL levels revealed significant (p<0.05) differences between group ages, but within group age 31-40 years were no significant (p˃0.05) differences. On the other hand, result of this study showed a significant (p<0.05) differences in kidney functions (urea, creatinine, and salts) when compared its with normal ranges. However serum testosterone showed a significant (p<0.05) differences with all ages of women, the progesterone showed no significant (p˃0.05) differences. Results revealed that consumption of 1gm daily of ginger powder significantly increased blood Hb, cholesterol, lipid profile, testosterone hormone, and improved kidney functions. So that we can suggest that ginger may be a promising in kidney and fertility function. In addition, its improve the biochemical parameters Keywords: ginger-biochemical parameter-lipid profile- kidney function- hormone

    The study of chemical content and aqueous and alcoholic extracts of Aplomb's  fruit and then detect the chemical components effective it aggregates and also, studying the effectiveness of inhibitory to extracts toward isolates bacterial different: E.coli, Pseudomonas flurscence, Salmonella, Shegilla and Staphylococcus aureus, where the results showed that the fruit Alpmbr containing 63.9% carbohydrate, 8.6% protein, 6.7% ash and 9.9% fat, so that the fruit Alpmbr high content of carbohydrates and fat shows that fat contains a high percentage of saturated fats, such as fatty acid, lauric acid ratio was 48.3% and Myristic acid was 15.8%, as well as that it contains a significant proportion of unsaturated fatty acid such as oleic by 12.4%, which is an important and basic nutrition and health for human. The fruit Alpmbr of mineral content was high proportion of potassium 29 ppm and sodium element was 13 ppm. It was found that either metallic zinc and calcium were accepted by Iraqi Standard. Heavy metals such as Cadmium, chromium and copper were not diagnose which is toxic elements, so it may be considered the fruit of Alpmbr is a safe fruits to-use and useful for health. To test the activity of the functional chemical components, it was found that high content of alkaloids, Saponin, Comarines, and Gums, and a reasonable rates of resins and Steroid, multiple phenols, flavonoids and Glycosides, tannins and oily nitrogeneous materials oily with low content. The pH of the aqueous extracts is 7.0 and alcoholic extract was 6.5 that means the fruits is neutral acidity. As for the inhibition  activity toward the bacterial isolates were higher effective inhibitory concentration 200mg / ml of aqueous extracts a diameter of 26mm against Pseudomonas flurscence and 25 mm for the both of Salmonella and E.coli. While, it decrease significantly to 19mm towards both Shegilla and Staphylococcus aureus. But with alcoholic extract concentration 200mg / ml has decreased significantly to 25 mm diameter towards Staphylococcus aureus and 20mm in E.coli and Shegilla.  Also the same significant decreases towards the Salmonella 19mm and 16mm towards the bacteria Pseudomonas flurscence. The sensitivity of the bacterial isolates for the  antibiotics inhibition diameters was 20 mm, of Erthromycin against Salmonella.  And the diameter of Oxacillin was 17 mm against Staphylococcus aureus, but Optimdex T was a very highly effective against all bacterial isolates.

    Some new complexes of 4-(5-(1,5-dimethyl-3-oxo-2-phenyl pyrazolidin-4- ylimino)-3,3-dimethyl cyclohexylideneamino) -1,5- dimethyl-2- phenyl -1H- pyrazol -3(2H) –one (L) with Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Pd(II), Re(V) and Pt(IV) were prepared. The ligand and its metal complexes were characterized by phisco- chemical spectroscopic techniques. The spectral data were suggested that the (L) as a neutral tetradentate ligand is coordinated with the metal ions through two nitrogen and two oxygen atoms. These studies revealed Octahedral geometries for all metal complexes, except square planar for Pd(II) complex. Moreover, the thermodynamic activation parameters, such as ?E*, ?H, ?S, ?G and K are calculated from the TGA curves using Coats –Redfern method. Hyper Chem -8 program has been used to predict structural geometries for compounds in gas phase. The heat of formation (?Hf) and bin ding energy (?Eb) at 298 °K for the free ligand and its metal complexes were calculated by PM3 method. The synthesized ligands and their metal complexes were screened for their biological activity against bacterial species, two Gram positive bacteria (Bacillus subtilis and Staphylococcus aureus) and two Gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa)

    Understanding unethical behaviour in the workplace : the CUBT model

    Get PDF
    126 leaves : ill. ; 29 cmIncludes abstract and appendices.Includes bibliographical references (leaves 103-112).Despite the advances in research on social contagions, personality and contextual factors, there has been no attempt to test the effect of coworker contagion on unethical behaviour in a comprehensive model. There is also a lack of research that attempted to identify a threshold for unethical behaviour. This dissertation provided a framework for testing coworker contagions and unethical behaviour threshold: The Contagious Unethical Behaviour Threshold (CUBT) model. Through a three-study package, the dissertation assessed the theoretical and empirical viability of coworker contagion levels, that is, the number of employees committing unethical behaviour, along with personal values (idealism and relativism) and contexts (risks and rewards) that moderate contagion effects on unethical behaviour. The dissertation also assessed the threshold concept, the point beyond which coworker contagions result in a clear increase in unethical behaviour likelihood. The first study found some support for the existence of a threshold concept based on a qualitative assessment of the effect of coworker contagion levels on unethical behaviour likelihood. Findings from the three studies strongly suggest that coworker contagion levels affected unethical behaviour likelihood. Most statistically significant interactions of personal values and contextual factors involved coworker contagion levels (in the three studies, a total of nine interactions involved coworker contagion levels while a total of three interactions did not involve coworker contagion levels). In all three studies, the contagion effect prevailed over other variables. This work expands on unethical behaviour theory and demonstrates the importance of appreciating the complex interplay among predictors in influencing unethical behaviour

    The measurement of muscle strength in allergic response

    The purpose of this thesis was to show arelationship between muscle strength and allergicreactions. Clinics have for many years relied on whathave become traditional methods for testing for allergicreactions. These include such tests as the Patch testand the Skin-Prick test. Both these tests causediscomfort and irritation to sensitive patients.The historical development of allergies is outlined,showing that scientists and clinicians in the late 18thand early 19th century were aware of certain reactionswhich people showed to apparently normal non-reactivefoods. The development of methods of diagnosingallergies such as the elimination diet, which dates backto approx 1940, are surveyed. Current practices are alsostudied with the use of photographs. The reaction of theskin to modern day testing practices is shown. In somecases these reactions are quite violent.The Applied Kinesiology Test is examined as auniversally used test which when carried out by anexperienced Kinesiologist can give a true but highlysubjective response to a patients allergic condition.A system has been developed based on therelationship between muscle strength and allergies, thecomponents of this system were readily available atlittle cost. Once a basic system was built it waspossible to perform trials on patients at an establishedallergy clinic.With the aid of a data printer it became possible toprove first graphically and second statistically thatthere was a statistically valid relationship between themeasured muscle strength and allergies.The conclusion shows that the final version of theoperating system is capable of equaling the performanceof an experienced Kinesiologist, showing its results bothdigitally and graphically rather than subjectively.The various deductions and recommendations which aredetailed, point towards a readily marketable device whichcould represent a potential break through in modernallergy testing. The system will also open the way forclinicians to make an objective assessment of therelationship between muscle strength and allergicsensitivity via further research

    Get PDF
    A new series of transition metal complexes of Cu(II), Ni(II), Co(II) and Fe(III) have been synthesized from the Schiff base (L1) and (L2) derived from Semicarbazide hydro chloride and 4-chlorobenzaldehyde or 4-bromobenzaldehyde. The structural features have been arrived from their elemental analyses, magnetic susceptibility, molar conductivity, IR, UV-Vis. and 1H NMR spectral studies. The data show that the complexes have composition of [M(L)2](NO3)2 and [Fe(L)2 (NO3)2](NO3) where the M=Co(II),Ni(II) and Cu(II) ;L=L1and L2 type. The magnetic susceptibility and UV-Vis spectral data of the complexes suggest a square planer geometry for Co(II) and Cu(II) but Fe(III) octahedral geometry and Ni(II) tetrahedral geometry around the central metal ion.Hyper Chem-6 program has been used to predict structure geometries of compounds in gas phase .The electrostatic potential of the free ligands were calculated to investigate the reactive sites of the molecules .The heat of formation(?Hf ?) and binding energy(?Eb) at 298K for the free ligands and its metal complexes were calculated by using PM3 method
