Affective power of vandalism: youth vandal practices within the concept of affective labor
Authors: Simonova Irina A. 
Published: March 2019

The purpose of the article is an adaptation of the affective labor concept as a method for analyzing vandalism among young people. The article examines youth vandalism as a form of affective labor and identifies two types of effects. The first type deals with the experiences of the vandals themselves which cause the new subjectivity and collectivity; the second type refers to the effects experienced by the users of vandal-altered spaces: they begin to feel differently because the damage can seriously change the status, value, user qualities of the urban environment and the emotions it induces on inhabitants.
The paper analyzes youth vandalism as a strategy which not only transforms the urban space visually (physically) but also consciously constructs the affects transforming the subjectivity of young people, social positions and community forms of both the vandals themselves and the users of the city. This approach, reflecting the strategic nature of the young people’s vandal activity, shows that vandal practice should be understood as the practice of space occupation, its appropriation, its de- and reconstruction and should be based on social topology and general ideas of actor-network theory. The socio-philosophical conclusions in the paper are illustrated by the results of interviews involving 17 participants from 7 youth communities conducted in summer and autumn 2017 in Yekaterinburg. The photographs of the damaged urban spaces in various city districts were also taken; the data were mapped, and the photo database was marked according to geographical location and types of damaged buildings. This helped to draw certain conclusions about the youth vandalism phenomenon. The article outlines the prospects for the use of the proposed methodology in the analysis of vandal damage and in urban vandalism prevention activities.

Abstract
Postgraduate students use online databases for various academic activities. However, past studies have revealed low utilisation of online databases by postgraduate students in Nigeria. The general objective of this study was to examine the influence of user education and adjustment factors (perceived enjoyment and objective usability) on use of online databases by postgraduate students of four private universities in southwest Nigeria. A descriptive survey research design of the correlational type was used, and the population was comprised of 1,067 postgraduate students in four private universities. A sample size of 513 was selected through a purposive sampling technique. Data was collected using a questionnaire and analysed using descriptive and inferential statistics. Findings revealed varying degrees of usage, perceived enjoyment and objective usability of online databases among the respondents. The study established a significant relationship between: user education and use of online databases; perceived enjoyment and use of online databases; and objective usability and use of online databases. User education, perceived enjoyment and objective usability therefore influenced the use of online databases by the postgraduate students of the four universities.

Synthesis, Characterization and Antimicrobial Screening of New Schiff Bases Linked to Phthalimidyl Phenyl Sulfonate Moiety
Authors: Journal Baghdad Science 
Published: March 2019

A series of Schiff bases linked to phthalimidyl phenyl sulfonate moiety have been synthesized via multistep synthesis.	The first step involved reaction of phthalic anhydride with aniline producing N-phenyl phthalamic acid which was subsequently dehydrated to the corresponding N-phenyl phthalimide via treatment with acetic anhydride and anhydrous sodium acetate. The synthesized imide was treated with chlorosulfonic acid in the third step producing 4-(N-phthalimidyl) phenyl sulfonyl chloride which was introduced in reaction with 4-hydroxy acetophenone in the fourth step producing 4-[4-(N-phthalimidyl) phenyl sulfonate] acetophenone and this in turn was introduced successfully in condensation reaction with various aromatic primary amines affording the desired new Schiff bases. The newly synthesized compounds were characterized through spectral data including FTIR, 1HNMR and 13CNMR. Antimicrobial activity of the prepared Schiff bases was evaluated against two types of bacteria and one type of fungi and the new Schiff bases were found to exhibit good antimicrobial activity against the tested organisms.

The impact of a Schiff base namely 2-((thiophen-2-ylmethylene)amino)benzenethiol to corrode mild steel in 1 M HCl resolved was evaluated using different weight loss technique and scanning electron microscopy (SEM).different weight measurements to expand that the 2-((thiophen-2-ylmethylene) amino) benzenethiol inhibits the corrosion of mild steel through adsorbing of top for mild steel and block the active locality. The inhibitive impacts of 2-((thiophen-2-ylmethylene)amino)benzenethiol increase with increasing concentration and decrease with increasing temperature. SEM to checking revealed that the alloy surface was quite unaffected and formed protective film on its surface. The investigated inhibitor become as a shield for the mild steel surface from corrosive solution. Quantum chemical investigations corroborate experimental results well. The synthesized inhibitor was characterized employing NMR (nuclear magnetic resonance), FT-IR (Fourier-transform infrared) spectroscopies and CHN elemental analysis.
Studying HLA class I polymorphism in brain tumour patients
Authors: Journal Baghdad Science 
Published: March 2019

The present study aimed at shed light on the association between HLA-class I antigens (A, B and Cw) and brain tumours (meningioma and glioma) in the basis of their individual frequencies or two-locus association	A total of 52 brain tumour patients were enrolled in this study, with an age range of 7-68 years. The patients were divided into two clinical groups; meningioma (20 cases) and glioma (22 cases), while the remaining 10 cases represented other types of brain tumour. Control samples included 47 Iraqi Arab apparently healthy blood volunteers, with an age range of 15-50 year. Three HLA antigens showed a significant increased frequency in total patients as compared to controls. They were B13 (34.6 vs. 6.5%), B40 (15.4 vs. 2.2%) and Cw3 (15.4 vs. 2.2%). In contrast, B5 was significantly decreased (15.4 vs. 34.8%). In meningioma patients, only B13 was significantly increased (35.0 vs. 6.5%), while in glioma patients, B13 (36.4 vs. 6.5%) and Cw5 (36.4 vs. 2.2%) were significantly increased. Variations between patients and controls have been also encountered for the observed and expected HLA-two locus associations (B13-Cw3, B13-Cw5 and B40-Cw5).

Core Ideas
Long‐term irrigation with brackish water can extend the practice into water‐scarce regions.
ESEM in both dynamic and static modes is a promising technique to analyze soil impacts.
Changes linked to the hydrophilic behavior of soils can be detected.
We investigated soil response to irrigation with slightly brackish water (1200 mg L−1 total dissolved solids on average) in a semiarid environment at the microscopic scale using environmental scanning electron microscopy (ESEM) applied in static and dynamic modes, which allowed comparison between nonirrigated and 3‐yr‐irrigated soil samples to determine the impact of applied brackish water. Results indicate that (i) there was a change in soil hydrophilic behavior by the continuous accumulation of water‐borne salt in the soil matrix, (ii) compared with nonirrigated samples, the wetting process occurred more gradually for the 3‐yr‐irrigated sample, (iii) the wetting process started at a lower vapor pressure for the 3‐yr‐irrigated sample, (iv) water vapor pressure in the chamber at full saturation was lower for the 3‐yr‐irrigated sample, and (v) the presence of heavy metals in the soil was more frequent in irrigated samples. Our results show that ESEM is a useful technique to determine the impacts on soil of irrigation with slightly brackish water.
Estimating Deep Drainage Using Deep Soil Moisture Data under Young Irrigated Cropland in a Desert‐Oasis Ecotone, Northwest China

Published: March 2019

Core Ideas
Deep drainage rates under young cropland in the desert‐oasis region were investigated.
Deep drainage rates were estimated by a simulation approach based on deep soil moisture data.
Annual deep drainage averaged 468 mm; the annual deep drainage coefficient averaged 43%.
Deep drainage reduces agricultural water productivity under cropland recently converted from native desert soils (i.e., young cropland) and increases the risks of nutrient and pesticide leaching into groundwater in the desert‐oasis ecotone. However, the deep drainage rates under young cropland in these oasis environments remain unclear, especially for winter irrigation, a common practice in Northwest China. The objective of this study was to estimate the deep drainage rate using the HYDRUS‐1D model based on soil moisture data in the deep vadose zone. Soil moisture at depths ranging from 0 to 200 cm was measured using HydraProbe II soil sensors in maize (Zea mays L.) and wheat (Triticum aestivum L.) fields in 2015 and 2017, respectively. Using a novel simulation approach based on soil moisture data in the deep vadose zone, the HYDRUS‐1D model provided reliable estimates of deep drainage as confirmed by comparison with estimates from the soil water balance method and prior studies in the region. The annual deep drainage averaged 468 mm, and the annual deep drainage coefficient averaged 43% in the young croplands. The winter irrigation amount averaged 265 mm, and the deep drainage coefficient during winter averaged 21% in the young croplands. The sandy soil of the young cropland and inefficient irrigation scheduling are detrimental to water conservation, causing relatively large deep drainage losses and enhancing the risks of groundwater pollution.
Recent Advances and Challenges in Steroid Metabolomics for Biomarker Discovery
Authors: Kotłowska Alicja , Szefer Piotr 
Published: March 2019

Background:Steroid hormones belong to a group of low-molecular weight compounds which are responsible for maintenance of various body functions, thus, their accurate assessment is crucial for evaluation of biosynthetic defects. The development of reliable methods allowing disease diagnosis is essential to improve early detection of various disorders connected with altered steroidogenesis. Currently, the field of metabolomics offers several improvements in terms of sensitivity and specificity of the diagnostic methods when opposed to classical diagnostic approaches. The combination of hyphenated techniques and pattern recognition methods allows to carry out a comprehensive assessment of the slightest alterations in steroid metabolic pathways and can be applied as a tool for biomarker discovery.Methods:We have performed an extensive literature search applying various bibliographic databases for peer-reviewed articles concentrating on the applications of hyphenated techniques and pattern recognition methods incorporated into the steroid metabolomic approach for biomarker discovery.Results:The review discusses strengths, challenges and recent developments in steroidbased metabolomics. We present methods of sample collection and preparation, methods of separation and detection of steroid hormones in biological material, data analysis, and interpretation as well as examples of applications of steroid metabolomics for biomarker discovery (cancer, mental and central nervous system disorders, endocrine diseases, monitoring of drug therapy and doping control).Conclusion:Information presented in this review will be valuable to anyone interested in the application of metabolomics for biomarker discovery with a special emphasis on disorders of steroid hormone synthesis and metabolism.

Background:We aimed at exploring biological functions of differentially expressed miRNAs during carcinogenesis, to identify miRNAs dysegulations involved in DNA repair mechanisms, and to evaluate potential of miRNAs as prognostic and diagnostic biomarkers for early lung adenocarcinomas (LAC).Methods:We obtained 21 LAC and paired adjacent normal formalin-fixed, paraffinembedded lung tissues from patients who underwent curative resection for stage I LAC. We compared expression levels of eight miRNAs involved in the DNA repair mechanism between LAC and adjacent tissues.Results:Expressions of Hsa-miR-9-5p, hsa-miR-24-3p, hsa-miR-125a-3p, hsa-miR- 125b-5p, hsa-miR-155-5p, and hsa-let-7a-5p were significantly up-regulated in stage I LAC tissues compared with those in the adjacent tissues. In addition, expressions of hsa-mir-9-5p, hsa-mir-24-3p, hsa-mir-125a-3p, hsa-mir-125b-5p, and hsa-mir-155-5p were significantly up-regulated in stage Ia LAC tissues, whereas expressions of hsa-mir- 125a-3p and hsa-mir-125b-5p were significantly up-regulated in stage Ib LAC tissues. Receiver operating characteristic (ROC) analysis revealed that AUROC of hsa-mir-125b- 5p was 0.875 (P < 0.001).Conclusion:Expression of hsa-mir-125b-5p could be used to distinguish LAC from adjacent tissues. Our result suggests that hsa-mir125b-5p can be a prognostic and diagnostic biomarker for LAC.
A Developmental Psychopathology Perspective of Obsessive-Compulsive Disorder
Authors: Capawana Michael R. 
Published: March 2019

Objective:This integrative review explores Obsessive-Compulsive Disorder (OCD) from the perspective of developmental psychopathology, in terms of its multifaceted etiology and course.Background:Individuals affected by OCD experience intrusive and undesired thoughts accompanied by behaviors used to mitigate the unwanted images. Accordingly, there are several sub-types and personality dispositions reflective of the overall continuum of OCD, spanning normality and psychopathology. The etiology is complex, with generalized psychological and biological vulnerabilities, as well as contributors from life stress. Moreover, OCD is a disorder with a highly comorbid and overlapping presence; therefore, difficulties may arise when differentiating between OCD and other problems.Conclusion:Treatment non-responsiveness is a pervasive trend in persons afflicted with OCD, but the most effective approach likely involves a stepped-care model incorporating cognitive-behavioral psychotherapy and psychotropic medications. Other considerations will also be discussed.
