We tweet Arabic; I tweet English: self-concept, language and social media

© 2019 The Authors Differences in self-concept have been observed across cultures. Participants from collectivist societies tend to describe themselves using social and relational attributes (mother, student, Arab) more frequently than their individualist counterparts, who tend to rely more heavily on personal attributes (fun, tall, beautiful). Much of this past research has relied on relatively small samples of college students, tasked with spontaneously reporting self-concepts in classroom settings. The present study re-examines these ideas using data extracted from Twitter, the popular social media platform. In analysis one, the Twitter biographies of individuals exclusively posting messages in English (N = 500) and those posting only in Arabic (N = 500) were content analyzed and quantified for differences in the frequency of personal versus social attribute use. Analysis two applied a bilingual word counting algorithm to the biographies of a larger sample of Twitter users (N = 242,162), exploring the relative frequency of social attributes, specifically familial roles (e.g. mother, father, daughter, son), across both English and Arabic users. In analysis one, the Twitter biographies of exclusive Arabic users contained significantly more social attributes than their English using counterparts. In analysis two, Arabic biographies contained significantly more familial references than their English language counterparts. These findings support the idea that cultural values may influence self-construal. Big data extracted from social media platforms appear to offer a useful means of exploring self-concept across cultures and languages

Inhibition of cyclophosphomide mutagenicity using Glycyrrihza glabra root extract

The aims of the studying is using methanolic - water extract of the Glycyrrihza glabra root for inhibition the mutagenicity of anticancer drug by cytogenetic assays in vivo in three interaction between the drug and extract. The result shows that the extract is bioantimutagenesis. The treatment by extract after drug causes increase mitotic index and decrease chromosome aberration and sperm head abnormalities. The thin layer chromatography of the extract show that is contains different polar compounds

Cytogenetic Effects of Benzene on Human Blood Cells

The study aims to investigate the cytogenetic effect of benzene on human blood cells in vitro using chromosomes abnormalities and mitotic index test. Different concentrations of benzene were added to human blood culture at 24 hour, then cells were arrested at metaphase to detect chromosomes malformations and its proliferation, the result show that benzene causes increased in mitotic index level and different aberrations in chromosomes which increased with benzene concentrations. Keywords: Benzene, Chromosomes abnormalities, Mitotic index

Cytotoxic and Genotoxic Effect of Aflatoxin B1

The aims of study is to determine cytogenetic and genotoxic effect of aflatoxin B1 in vivo, cytogenetic tests are used in studying include chromosome malformation, cell proliferation and plast index test in bone marrow cell in Wight albino rats, the results show that toxin causes Varity in chromosome malformation and increased the rate of it, so it increased in cell proliferation and plast index value compare with negative control

The Prevalence of Microalbuminuria in Type 2 Diabetes Mellitus Patients in Al-Husain Hospital in Karbala Province- Iraq

This study is performed to assessment of the long term glycaemic hemoglobin (HbA1c) to determine the prevalence of microalbuminuria and to find the risk factors for developing microalbuminuria and consequence nephropathy in patients with type 2 diabetes. The prevalence of microalbuminuria in our study is high (59%) and the percent of and the risk factors that accompanied microalbuminuria are high blood pressure, elevated fasting blood glucose and poor glycemic Diabetes mellitus (D.M.) is a group of metabolic diseases characterized by hyperglycemia poor glycemic control also high  (92.3%) with control

In vivo study of antimutagenic and antioxidant activity of Glycyrrihza glabra root extract

The studying was aimed to inhibition the mutagenecity and oxidation of genomic DNA by use methanol-water extract of Glycyrrihza glabra root (GL) against anticancer drug cyclophosphomide in rats by use DNA fragmentation test, the extract characterized by thin layer chromatography TLC, and antioxidant activity by use β- carotene spray, the experiment design to use tow single dose of GL and single dose of the drug in three interaction, extract before, with and after the drug to investigate the mechanism of which extract effect inside cell. Four multiple doses for drug and extract to investigate the accumulation effect in DNA the results show that extract is contain of different polar compound and have antioxidant activity, so the extract is bio-antimutagenesis and poor dismutagenesis activity, the extract can inhibit accumulation effect of mutagenecity and oxidation activity of the drug

Total and differential leukocytes count in type 2 diabetes mellitus patients in Iraq

To find the correlation between total and differential leukocytes count and the presence of microalbuminuria in diabetic patients. The results show significant positive correlation between total leukocytes count and microalbuminuria in males and females also there is significant positive correlation between neutrophils count and microalbuminuria in males and females but there is no correlation with other types of leukocytes

Effect of Pollutant Water on Some Organs and Blood Parameters in Rats

Water pollution causes dangerous problems in our life. The present study aims to determination effect of chemical polluted water on blood parameter and histological changes in rat organs using Wight albino rats. For this study Hilla fabric plant waste water is used as drinking water to the rats for 30 days. Results show that polluted water causes increased in W.B.Cs count and histopathological changes in liver and kidne

Impact of quantum confinement on transport and the electrostatic driven performance of silicon nanowire transistors at the scaling limit

In this work we investigate the impact of quantum mechanical effects on the device performance of n-type silicon nanowire transistors (NWT) for possible future CMOS applications at the scaling limit. For the purpose of this paper, we created Si NWTs with two channel crystallographic orientations <110> and <100> and six different cross-section profiles. In the first part, we study the impact of quantum corrections on the gate capacitance and mobile charge in the channel. The mobile charge to gate capacitance ratio, which is an indicator of the intrinsic performance of the NWTs, is also investigated. The influence of the rotating of the NWTs cross-sectional geometry by 90o on charge distribution in the channel is also studied. We compare the correlation between the charge profile in the channel and cross-sectional dimension for circular transistor with four different cross-sections diameters: 5nm, 6nm, 7nm and 8nm. In the second part of this paper, we expand the computational study by including different gate lengths for some of the Si NWTs. As a result, we establish a correlation between the mobile charge distribution in the channel and the gate capacitance, drain-induced barrier lowering (DIBL) and the subthreshold slope (SS). All calculations are based on a quantum mechanical description of the mobile charge distribution in the channel. This description is based on the solution of the Schrödinger equation in NWT cross sections along the current path, which is mandatory for nanowires with such ultra-scale dimensions

Cell Cycle Response to Low Power Laser Irradiation in Jurkat E6.1 T-lymphocyte Cell Line

Low-power laser irradiation (LPLI) effects on cell cycle progression in Jurkat E6.1 T-lymphocyte leukemia (JETL) cells were examined in vitro at 635nm (visible) and 780nm (near infrared) wavelengths. The cells were exposed to an energy density of 9.174 J/cm2, and then examined 24, 48 and 72 hours post-irradiation. Cell cycle analysis by flow cytometry at 24 hours post-irradiation revealed that the three phases (G0/G1, S and G2/M) of cultured JETL cells showed different percentages in LPLI (635nm and 780nm) and unirradiated cultures, but S phase cells were observed with significant increased percentages (55.6 and 55.7%, respectively) compared to controls (37.3%). At 48 hours, again cells at S phase were observed with much higher percentages than control cells (48.2 and 51.5% vs. 29.9%, respectively), and the difference was significant (P ? 0.05). At 72 hours, the S phase cells were also observed with much higher percentages than control cells (33.1 and 32.6% vs. 21.3%, respectively), and the difference was also significant (P ? 0.05).
