Background and objective This study aims at assessing the prevalence and risk factors of Adjustment disorder (AD), the AD subtypes, and the common causing stressors. Patients and methods A cross sectional study was conducted at outpatient psychiatric clinic in Duhok City from July 2008 to July 2009. 637 patients equal and above 18 of both genders were selected randomly. SCID-I/P (Version 2.0) was adopted to diagnose patients with AD. SPSS (version 21), was used for data analysis. Results The study showed that the prevalence of AD was 11.5%. It was more common among youngest age group (15–25 years) with a rate 69.9% (p = 0.001) while lowest educational level (illiterate and primary) 53.5% (p = 0.040), single 54.8% (p < 0.001), students 39.7 (p < 0.001) and from urban areas 71.2% (p = 0.012) with statistically significant association. Although AD was more common among females (61.6%), no significant association was found between AD and gender (p = 0.380). The most common subtype of AD was AD with mixed anxiety and depressed mood (34.2%) and was the commonest among females (19.2%) followed by AD with Anxiety subtype 30.1% which was the commonest among males (13.7%). The commonest psychosocial stressor was the illnesses (28.8%) followed by love affairs (26%) and domestic problems (16.4%). Conclusions The prevalence of AD was found to be high. The risk factors included young, low educational level, single, students, and those from urban areas. The most common subtype was AD with mixed anxiety and depressed mood and the commonest psychosocial stressor was the illnesses followed by love affairs and domestic problems. © 2017 Elsevier B.V.

Toxoplasmosis is a protozoan infection of humans and animals caused by Toxoplasma gondii, and it’s continuous public health and food safety issue. The tachyzoites (Tg) of T. gondii are the most important stage, as they come in direct contact with immune cells such as a macrophage. Tg can modulate and prevent apoptosis of immune cells while promoting survival of the pathogen. Infections caused by Tg can be eradicated if immune cells could stimulate apoptosis and kill pathogens upon exposure. Apoptosis is characterized by the release of mediators, namely Caspases (Cas). New means are required for inducing apoptosis and enhance immunity in the infected host cell to control toxoplasmosis. The present study investigated whether Synthetic Immuno-stimulatory Glycans (SIGs) influence Cas and Nitric oxide (NO) release and led to Tg damage. Galβ1- 3Gal-PAA-fluor (SIG1), Fucα1-4GlcNAcβ-PAA-fluor (SIG2) and GlcNAcβ1-3GalNAcα-PAA-fluor (SIG3) constituted samples studied principally. Murine macrophage had been exposed to the Tg then the SIGs effects on Cas and NO production were determined after 20 hours of pathogen phagocytosis. Here we report that the SIGs had potent in vitro activity against T. gondii; SIG2 was more effective than SIG1 and SIG3, representative by SIG2 treated infected macrophages can induced infected macrophages to release Cas1, 3, and 9. Maximum production of NO by infected macrophages was noticed following the expoxure to all SIGs. Therefore the present study provided the method for the selection of SIGs ligands bearing immunostimulatory factor and apoptotic stimuli properties. © 2017, University of Mosul - College of Veterinary Medicine.

Introduction: There is increasing evidence on association between vitamin D insufficiency and diabetes, but the impact of vitamin D status on glycaemic status and vice versa, has not been well reported. Our aim was to investigate the level of 25-hydroxyvitamin D(25(OH)D) and the prevalence of vitamin D abnormalities in patients with diabetes mellitus (DM) type2 and in those without diabetes; and to ascertain the impact of 25(OH)D levels on glycaemic control and vice versa. Material and Methods: Serum 25(OH) D was determined in 337 Kurd patients with DM type2 and in 146 patients without DM type2. Its correlation with the marker of glycaemic control (HbA1c) as well as with anthropometric parameters (age, gender, and body mass index), diabetes duration, and serum blood glucose was examined. Discussion: The mean ± SD values for serum 25hydroxy (OH) D levels of diabetic patients was 25.6± 12.6 ng/ml and those for the controls was 34.1±14.7 ng/ml (p<0.01). The prevalence of vitamin D insufficiency was significantly higher among diabetic patients than among the controls(53.7% vs. 29.4%, p<0.001). This finding was still true even after the means of serum 25 (OH) D levels were adjusted to those of severe vitamin D deficiency (4.4% vs. 0.68%).Patients with poor glycaemic control had a higher prevalence of low vitamin D status (90%) than those with sufficient vitamin D levels (76%). As compared to diabetics with a good and fair glycaemic control, diabetics with a poor glycaemic control exhibited lower 25(OH)D levels (p<0.01) and a higher prevalence of low vitamin D status (89% vs. 4% and 7%) respectively. Patients with a diabetes duration of more than 5 years also had a higher prevalence of low vitamin D status as compared to vitamin D sufficient group (51% vs. 40%). A statistically negative significant correlation between serum 25 (OH) D levels and HbA1c % was found in diabetic patients (r=0.238, p<0.01). Conclusion: A low vitamin D status is present in two thirds of patients with DM type 2, particularly among diabetics with poor glycaemic control and among those with longer diabetes durations. This may reflect the additive effect of glycaemic control on vitamin D status.

This paper presents a new feature-selection approach based on the cuttlefish optimization algorithm which is used for intrusion detection systems (IDSs). Because IDSs deal with a large amount of data, one of the crucial tasks of IDSs is to keep the best quality of features that represent the whole data and remove the redundant and irrelevant features. The proposed model uses the cuttlefish algorithm (CFA) as a search strategy to ascertain the optimal subset of features and the decision tree (DT) classifier as a judgement on the selected features that are produced by the CFA. The KDD Cup 99 dataset is used to evaluate the proposed model. The results show that the feature subset obtained by using CFA gives a higher detection rate and accuracy rate with a lower false alarm rate, when compared with the obtained results using all features. © 2014 Elsevier Ltd.

Consistent finite strain Plate constitutive relations are derived based on a hyperelastic formulation for an isotropic material. Plate equilibrium equations under finite strain are derived following a static kinematic approach. Three Euler angles and four shear angles, based on Timoshenko beam theory, represent the kinematics of the deformations in the plate cross section. The Green deformation tensor has been expressed in term of a deformation tensor associated with the deformation and stretches of an embedded plate element. Buckling formulation includes the in-plane axial deformation prior to buckling and transverse as well as in-plane shear deformations. Numerical results for a simply supported thick plate under uni-axial compression force are presented. Copyright © 2016 Techno-Press, Ltd.

This study analyzes the effects of toxic, hydraulic, and organic shocks on the performance of a lab-scale sequencing batch reactor (SBR) with a capacity of 5. L. Petroleum refinery wastewater (PRWW) was treated with an organic loading rate (OLR) of approximately 0.3. kg chemical oxygen demand (COD)/kg MLSS. d at 12.8. h hydraulic retention time (HRT). A considerable variation in the COD was observed for organic, toxic, hydraulic, and combined shocks, and the worst values observed were 68.9, 77.1, 70.2, and 57.8%, respectively. Improved control of toxic shock loads of 10 and 20. mg/L of chromium (VI) was identified. The system was adversely affected by the organic shock when a shock load thrice the normal value was used, and this behavior was repeated when the hydraulic shock was 4.8. h HRT. The empirical recovery period was greater than the theoretical period because of the inhibitory effects of phenols, sulfides, high oil, and grease in the PRWW. The system recovery rates from the shocks were in the following order: toxic, organic, hydraulic, and combined shocks. System failure occurred when the combined shocks of organic and hydraulic were applied. The system was resumed by replacing the PRWW with glucose, and the OLR was reduced to half its initial value. © 2013 Elsevier B.V.

One of the main goals during load calculations and vibration analysis for gears is the determination of deformation and stress state in teeth contact zones. This paper describes development of the finite element model for simultaneously monitoring the deformation and stress state of teeth flanks and teeth fillets for spur gears during the contact load period. The paper also describes the Finite Element Method simulation of contact conditions for spur gears teeth with complete 3 dimension meshing model. A suitable analysis is performed in order to select a meshed gears model which is sufficiently economic and in same time sufficiently geometrically accurate. The special algorithm for the tooth profile drawing is developed and built in currently available software (Ansys 10) for Finite Element Analysis to assure drawing of real flanks contact geometry. The optimal mesh size level is chosen, too. The described finite element models are made for the spur gear teeth during the dynamic loading state. The obtained numerical results are suitable for tracking deformation and stress hesitation with time and investigating the effect of damping coefficient on the obtained results. © 2006-2012 Asian Research Publishing Network (ARPN).

Haemoglobinopathies including the thalassemias and sickle cell disease are known to be prevalent inherited disorders in most Arab countries with varying prevalence rates and molecular characterisation. β-thalassemia is encountered in polymorphic frequencies in almost all Arab countries with carrier rates of 1-11 % and a varying number of mutations. The most widespread mutation in Lebanon, Egypt, Syria, Jordan, Tunisia and Algeria is the IVS-I-110 (G>A). In the Eastern Arabian Peninsula, the Asian Indian mutations (IVS-I-5 (G>C), codons 8/9 (+G) and IVS-I (-25 bp del)) are more common. The α-thalassemias are encountered in the majority of Arab countries in frequencies ranging from 1 to 58 % with the highest frequencies reported from Gulf countries. The (-α3.7) mutation is the most frequent followed by the non-deletional α2 polyadenylation signal mutation (AATAAA>AATAAG) and the α2 IVS1 5-bp deletion. The rates of sickle cell trait in Arab countries range from 0.3 to 30 %, with the Benin, the Arab-Indian and the Bantu haplotypes constituting the bulk of the haplotypes, leading to two major phenotypes; a mild one associated with the Arab-Indian and a severe one with the Benin and Bantu haplotypes. Public health approaches targeting prevention of haemoglobinopathies in Arab countries include newborn screening for sickle cell disease, and premarital screening for carriers of β-thalassemia and sickle cell disease. These services are still patchy and inadequate in many Arab countries recommending the upgrade of these services with strengthening of the education and training of health care providers and raising public awareness on the feasibility of prevention and care for haemoglobinopathies. © 2012 Springer-Verlag Berlin Heidelberg.

An approach for continuous daytime cloud classification system through satellite images is presented. The system is based on spectral ratio values as input features and a modified version of probabilistic neural network (PNN), named Quick PNN (QPNN), as a classifier. The use of spectral ratio values makes the system more efficient in detecting the minor changes in cloud spectral properties, leading to better classification capability. The modification to PNN consists of shrinking the hidden layer which is accomplished by performing K-means clustering on the training data of each class separately. Thus, for each class, instead of presenting all the training data samples in the hidden layer nodes, only the means of the resultant clusters are presented. The training data and the class labels are derived through the generation and interpretation of ratio images. The application of the approach to Meteosat-8 images has shown the separation of eight classes, including low clouds, middle clouds, high clouds, areas of high water vapor, sea surface, and land. The average accuracy of the system is 87.15% with a range of 84%-91% for the cloud and area of high water vapor classes, 93% for sea surface class, and 85% for land surface class. The computation time of the classification mode, including image ratioing and QPNN operations, is less than 1 min, which is good for continuous cloud classification and monitoring. The approach can be adapted to any multichannel satellite sensor only by using proper combination of ratio images. © 2011 IEEE.
