The United States Supreme Court case Ziglar v. Abbasi and the severe psychological and physiological harms of solitary confinement

In the aftermath of the September 11, 2001 terrorist attacks, a group of Middle Eastern, North African, and South Asian men was arrested for immigration violations, held as “terrorism suspects,” and detained in federal prison for months. Each of these men was, or was believed to be, Muslim or Arab. These men (the “Detainees”) alleged that they were detained solely on the basis of their religion or race, and that there was no individualized basis to suspect them of terrorism. They further alleged that, during their detention, they were abused physically and verbally and subjected to inhumane conditions, including solitary confinement. After several months, the Detainees were cleared of any connection to terrorism and deported. The Detainees allege that they suffered severe psychological and physiological harms as a result of the conditions of their detention and that they continue to suffer the effects of this trauma today

PHYTOCHEMICAL CONSTITUENTS, ANTIOXIDANT ACTIVITY, TOTAL PHENOLIC AND FLAVONOID CONTENTS OF ARISARUM VULGARE SEEDS

Interest in toxic plants is increasing because it is recognised that these plants contain bioactive compounds and then, have medicinal virtues. So, medicinal plants are of great importance to the health. Also, many papers have reported that the major pharmacological proprieties of medicinal plants are associated and attributed to their antioxidant activity, then; much attention is being paid to antioxidant compounds In this work, we targeted Arisarum vulgare plant growing in El-Kala National Park. This park is situated in the extreme North-East of Algeria (36°55'--36°90'N; 08°16'-08°43'E) is a specifi c site recognized for its fl oristic wealth, it presents a remarkable PHYTOCHEMICAL CONSTITUENTS, ANTIOXIDANT ACTIVITY, TOTAL PHENOLIC AND FLAVONOID CONTENTS OF ARISARUM VULGARE SEEDS Hadjer Kadri, Salah Eddine Djilani, Abdelouaheb Djilani LSBO Department of Chemistry, Badji Mokhtar University B.P. 12, Annaba, Algeria ABSTRACT Background. Arisarum vulgare is screened and its total phenolic compounds and total fl avonoid contents were measured. In addition, the antioxidant capacity of the methanol-water (7:3) extract of this plant is evaluated by DPPH (2,2-diphenyl-1 picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic)) tests expressed by Vitamin C Equivalent Antioxidant Capacity (VCEAC). HPLC analyses are carried out to identify some polyphenols. The aim of this study is to identify, to quantify the phenolic compounds contained in the seeds of A. vulgare, and to evaluate their antioxidant capacity. Material and methods. Methanol-water (7:3) extract and three fraction obtained from silica gel column chromatography of A. vulgare were assayed by using RP-HPLC, spectrophotometric analyses, DPPH and ABTS tests. Results. Results obtained in the present study, revealed that total phenolic and fl avonoids of methanol-water extract of A. vulgare seeds were respectively 1.2 g GAE and 0.34 g QE per 100 g of plant extract dry weight. The total antioxidant capacity expressed as vitamin C equivalent antioxidant capacity (VCEAC) per 100 g of plant extract, obtained by ABTS and DPPH tests were respectively 1.3 g and 0.99 g VCE per 100 g dry weight. On the other hand RP-HPLC analyses reveal that the main phenolic compounds identified in the methanol-water (7:3) extract are gallic acid, caffeic acid and rutin. Conclusions. The results reveal that the methanol-water extract of A. vulgare seeds possesses strong antioxidative properties in vitro. Results confi rmed by high polyphenols and fl avonoids contents and corroborated by HPLC identifi cations

A quantitative analysis of 117 individuals was treated. The study confirmed a significant statistical impact of the work content characteristics related to the Ergonomic approach on the employees’ performance. The findings suggested that attention be given to the job design in line with the Ergonomic approach standard, and also taking into account the compatibility between the employee’s psychology and job characteristics to ensure a high performance, therefore; achieving the efficiency and the productivity of the Company

Interactive open-pit design using parameterization techniques

The standard approach to open pit design is to optimize the pit shape using the criterion of maximum total profit on the basis of a revenue block model of the orebody. There are some difficult problems inherent in such an approach. For example, scheduling and production rates will have a significant effect on the shape of the pit; if the bulk of the rich (and thus high revenue earning) ore is at the bottom of the pit and will not be mined until near the end of the life of the mine, then the time value of money may make the simple revenue block approach meaningless. In addition, optimality is a function of economic parameters which may change significantly over time. The aim of the parametric approach is to express the solution (Le., the optimal pit shape) as a function of one or more parameters such as costs, prices or cut-off grade. Matheron's parametric approach is to use a grade block model together with the techniques of functional analysis without making any economic assumptions. This leads to a set of technically optimal nested pits which can be used for mine scheduling. Whittle uses the traditional revenue block approach with the Lerchs-Grossmann algorithm and finds a set of optimal pits which are functions of the price/cost ratio. The aim of this project is to combine the two approaches mentioned above and provide a complete parametric solution in terms of technical and economic parameters. The project includes the development of an interactive computer program for the parametric design and scheduling of open pits. The author reviews the literature on optimal open pit design and scheduling and then provides an overview of the parameterization method. In this research project the parameterization method has been extended to allow for the selection of an economically optimum pit. Scheduling is then discussed in detail and a new method that combines linear programming and user-activated simulation is introduced. All software developed during this project is described in detail in the final Chapter

Detección de caídas para dispositivos de bajo coste

Con el aumento de la calidad de vida de las personas, las políticas sociales y las mejoras en medicina, cada vez las personas viven más tiempo. Por otro lado, el ritmo de vida actual muchas veces es incompatible con la responsabilidad de cuidar a nuestros familiares, que es común que vivan solos aun siendo muy mayores. Esto genera situaciones domésticas potencialmente dañinas para ellos. Por ejemplo, un tipo de accidente muy común en las casas de las personas mayores son las caídas. En este trabajo, se propone un sistema de detección de caídas capaz de correr en hardware de bajo coste con el objetivo de avisar a los familiares y minimizar el impacto de la posible caída
