Black Life Mater: Debunked!

The Black Lives Matter movement emerged in 2012 to combat racial targeting after the death of Trayvon Martin. The purpose of the movement, according to the Black Lives Matter Guiding Principles, is to serve as “an ideological and political intervention in a world where Black lives are systematically and intentionally targeted for demise” and “an affirmation of Black folks’ contributions to this society, our humanity, and our resilience in the face of deadly oppression.” From meetings with Democratic National Convention leaders, to attending a meeting at the White House at the invitation of the President, the Black Lives Matter movement is making strides in eliminating racial profiling in our society

Contaminación fúngica de frutos secos de vid y detección de ocratoxina en jugo de uva enDuhok, Iraq

Introduction: Dried vine fruits (raisins) and their juice are widely consumed by human as a diet. Raisins have been shown highly contaminated with ochratoxin A (OTA) and OTA-producing fungi. Ochratoxin A is a potent nephrotoxic and carcinogen to human and animals. Materials and Methods: Dried vine fruit samples was obtained from local shops for fruit juice and soft drinks in Duhok province. Two different media, Dichloran R ose Ben gal Chloromphenicol Agar (DRBC) and Dichloran 18 % Glycerol Agar (DG-18) was used for the counting and isolation of fungi from dried vine fruits. Grape juice were prepared from dried vine fruit after blending with water in a commercial blender. Natural contamination with ochratoxin A was detected by LC-MS/MS technique. Results and Discussion: All samples confirmed to be contaminated with fungi with various degrees. A total of 19 filamentous genera of fungi as well to Yeasts and non sporulation mycelium was detected. Predominant genera detected on both media were Aspergillus and Penicillium. Detected value of ochratoxn A in juices obtained from dried vine fruits was between 0.37 ng/ml to 1.85 ng/ml. Samples contaminated with ochratoxin A were associated withAspergillus carbonarius, A. niger aggregate, A. sclerotium, A. ochraceus, and Penicillum verrucosum. Conclusion: Dried vines fruit were highly contaminated with a broad spectrum of filamentous fungi. Black aspergilli were the most detected species from samples naturally contaminated with ochratoxin

Waist Circumference Thresholds Provide an Accurate and Widely Applicable Method for the Discrimination of Diabetes

Excess weight, particularly central obesity, is recognized to be a major determinant of diabetes risk in all populations, with the magnitude of the association reported as being stronger in Asians than whites (1–3). Consequently, indicators of overweight have been incorporated into several guidelines for the early identification of individuals with type 2 diabetes (4). However, the anthropometric cut points for different ethnic groups have been determined in various ways, leading to uncertainty about their applicability to diabetes screening. Here, we clarify current uncertainty regarding ethnic differences in the relationship between overweight and diabetes and whether there is a single measure of overweight that can be determined routinely and applied universally in clinical practice to facilitate earlier detection of diabetes in the general population

TINJAUAN HUKUM ISLAM TERHADAP KLAUSULA BAKU DALAM PRAKTIK JUAL BELI DI KABUPATEN TAKALAR

AbstrakKlausula baku nampak aturan atau syarat-syarat yang telah disiapkan ditetapkan lebih dahulu secara sepihak, sedangkan Penerapan praktik jual beli diketahui melahirkan kewajiban secara bertimbal balik kepada para pihak yang membuat perjanjian jual beli tersebut.

For business activists in accordance with Article 1333 of the Civil Code, they are required to submit a material which according to the provisions must be a tradable material and at least a specified type. standard clause in the practice of buying and selling in maubel shops in Keluharan Manongkoki Takalar Regency develops, even though the system of buying and selling verbally, but the pattern of development of standard clauses that are scattered on the buying and selling system based on the provisions buyer's requirements. Islamic law against the practice of standard clauses in buying and selling, allows a custom to run as long as it does not conflict with Islamic law. The principle of the take it or leave it standard clause is in line with the khiyar concept applicable in Islamic law, namely the freedom for the buyer to continue or cancel a transaction. Manongkoki community needs to improve their creativity in making cabinets, chairs and tables so that many consumers like and buy them.Keywords: Islamic Law, Modern Justice, Supreme Court

Actividad antifúngica de algunos extractos de plantas medicinales contra algunos aislados de hongos.

Introduction: Fungi live everywhere in the environment, most of them are not dangerous, but some types of fungi can be harmful to humanhealth. The medicinal plants contain many antimicrobial components that make them recently used as powerful drugs. The aim of the present investigation was to examine the antifungal potential and minimum inhibitory concentration (MIC) of three plant extract: Aloe vera gel, cinnamon (Cinnamomum zeylanicum) and turmeric (Curcuma longa) against three fungal species: Aspergillus niger, Candida albicans and Fusarium oxysporum. Materials and Methods: The plant materials were extracted using solvents DMSO and ethanol and then were tested against the selected fungal isolates using well diffusion method. Results and Discussion: Antifungal activity of Aloe vera against Aspergillus niger showed MIC value of 25% whereas for Candida albicans and Fusarium oxysporum the MIC obtained was 100%. Both cinnamon and turmeric showed maximum potency against Aspergillus niger, Candida albicans and Fusarium oxysporum at highest MIC value of 100 %. The degree of inhibition increased correspondingly with increasing concentrations of the plant extracts. Conclusions: the tested plant extracts have an antifungal activity and could be used as alternative drugs

The Effectiveness of Scientific Stations Strategy in Achievement of the Seventh Grade Students in Dictation

The study aims to examine  the effectiveness of using the “scientific stations strategy” for grade seven students,  achievement in dictation in the Sultanate of Oman. In order to achieve this, the researchers prepared an achievement test and a guideline for   executing the strategy. The tool was checked for validity by a panel of area experts.  The reliability of the test was 0.84 as determined by Cronbach’s Alpha. The study sample consisted of two groups, where 24 female students  were taught dictation according to the scientific stations strategy, and 18 students were taught by the conventional method. The results of the post test showed that there is a statistically  significant difference in the mean scores between the two groups, in favour of the experimental group. Based on  these results, the researchers recommended making use of the science stations strategy by training teachers to use it in teaching dictation and in other language areas

Spatial quadratic solitons guided by narrow layers of a nonlinear material

We report analytical solutions for spatial solitons supported by layers of a quadratically nonlinear material embedded into a linear planar waveguide. A full set of symmetric, asymmetric, and antisymmetric modes pinned to a symmetric pair of the nonlinear layers is obtained. The solutions describe a bifurcation of the subcritical type, which accounts for the transition from the symmetric to asymmetric modes. The antisymmetric states (which do not undergo the bifurcation) are completely stable (the stability of the solitons pinned to the embedded layers is tested by means of numerical simulations). Exact solutions are also found for nonlinear layers embedded into a nonlinear waveguide, including the case when the uniform and localized nonlinearities have opposite signs (competing nonlinearities). For the layers embedded into the nonlinear medium, stability properties are explained by comparison to the respective cascading limit.Comment: J. Opt. Soc. Am. B, in pres

How Gender and Race Stereotypes Impact the Advancement of Scholars in STEM: Professors’ Biased Evaluations of Physics and Biology Post-doctoral Candidates

The current study examines how intersecting stereotypes about gender and race influence faculty perceptions of post-doctoral candidates in STEM fields in the United States. Using a fully-crossed, between-subjects experimental design biology and physics professors (N = 251) from eight large, public, U.S. research universities were asked to read one of eight identical curriculum vitae (CVs) depicting a hypothetical doctoral graduate applying for a post-doctoral position in their relevant field and rate them for competence, hireability, and likeability. The candidate’s name on the CV was used to manipulate race (Asian, Black, Latinx, and White) and gender (female or male), with all other aspects of the CV held constant across conditions. Faculty in physics exhibited a gender bias favoring the male candidates as more competent and more hirable than the otherwise identical female candidates. Faculty in both biology and physics demonstrated a racial bias, rating the Asian and White candidates as more competent than Black candidates overall. Further, physics faculty rated Asian and White candidates as more hirable than Black and Latinx candidates, whereas those in biology rated the Asian candidates as more hirable than the Black candidates. An interaction between candidate gender and race emerged for those in physics whereby women Black and Latinx candidates were rated the lowest in competence compared to all others. Women were rated more likeable than men candidates across departments. Our results highlight how understanding the underrepresentation of women and racial minorities in STEM requires examining both racial and gender biases as well as how they intersect

Blockchain-based student certificate management and system sharing using hyperledger fabric platform

One of the major capabilities of blockchain technology is the sharing of data in verifiable ways without losing control of information possession. Issuing and verifying student certifications for higher study applications or job recruitment require many steps that take days to complete and are considered time-consuming. Most universities around the world use centralized systems to control the entire procedure when a graduate applies for a job or postgraduate studies. Applying blockchain technology to certificate verification protocols through a comprehensive architecture provides authenticity and reduces time significantly. In this paper, a framework has been proposed to issue student certifications locally in addition to sharing them across the internet while maintaining control and ownership of the certifications. This framework leverages the advantages of blockchain technology to electronic certification sharing and verification. Applying the proposed blockchain-based certification system in universities will provide low latency for issuing, sharing, and verification of these certifications. The paper presents the proposed blockchain-based framework for e-certification sharing and an evaluation of the framework, which consists of measuring the average time to issue a certificate and transaction latency time.</p
