Rare Metals Mineralization in Pegmatite at Abu Rusheid Area, South Eastern Desert, Egypt

Two forms of pegmatite have been distinguished (segregations and dikes) hosted in the cataclastic rocks, at the Abu Rusheid area, southeastern Desert of Egypt. The cataclastic rocks covering an area about 2 km 2 , and composed of (from base to top); protomylonite, mylonite, ultramylonite, and quartzite with gradational contacts. The segregations are unzoned, flat lenses, less than 1 m, while the dikes, usually of the zoned type, have (2-15 m in length, and 0.3 m in width), trending NNW-SSE and dipping 10-30/ WSW parallel to banding of the cataclastic rocks. Albitization, chloritization, fluoritization and silicification are the major alteration processes in the cataclastics and pegmatites due to the effect of hydrothermal solution. The total REE content in the pegmatite ranges from 44 to 824 ppm with 342 ppm as the average. LREE is more enriched than the HREE in the pegmatite (LREE/HREE =7.8) and related to the presence of allanite-(Ce) and monazite–(Ce). Hydrothermal alteration during post-magmatic stages is shed light on the development of M-type tetrad effect in the REE pattern. The rare metals-bearing minerals such zircon, monazite – (Ce), allanite – (Ce), Nb-Ta minerals (columbite-(Fe) and euxenite-(Y), base metals (pyrite and molybdite), beryl and radioactive minerals (thorite, uranophane, torbernite and kasolite) have been found in the pegmatites. Isoconcentration maps show abnormal contents of Nb,Zr, Y, Pb, eU and eTh, and could be considered as low grade ores. The Abu Rusheid pegmatites show low-CaO content (1 % av.), high Fe/Mg ratio (5.9 av.), enrichment of HFSE (Nb, Zr, Y,U, Th), peraluminous, A-type post-orogenic tectonic setting and their mineral composition supporting the NYF nature of the pegmatites.
The net contribution of livestock to the supply of human edible protein: the case of Ireland

Abstract If current food consumption patterns continue, the agriculture sector must provide significantly more food in the coming years from the available land area. Some livestock systems engage in feed–food competition as arable land is used for livestock feed rather than as crops for food; reducing the global supply of food. There is a growing argument that to meet future-food demands sustainably, feed–food competition must be minimized. To this end, we evaluated the effectiveness of two refined metrics to quantify feed–food competition in three livestock systems; dairy and its beef, suckler beef and pig production in Ireland. The metrics are edible protein conversion ratio (EPCR) and the land-use ratio (LUR). The EPCR compares the amount of human digestible protein (HDP) in livestock feed against the amount of HDP the livestock produced, calculating how efficiently it produces HDP. However, the LUR compares the potential HDP from a crop system on the land used to produce the livestock's feed against the HDP the livestock system produced. In both metrics, a value <1 demonstrates an efficient system. The EPCR values for dairy beef (0.22) and suckler beef (0.29) systems consider them efficient producers, whereas pig production (1.51) is inefficient. The LUR values designate that only the dairy beef (0.58) is a net positive producer of HDP from the land used for its feed, with crop production producing more HDP than suckler beef (1.34) and pig production (1.73). Consequently, the LUR can be deemed to be more suitable to represent feed–food competition in livestock production.

Purpose – This paper examines the relationship between the institution’s organizational work-life-balance (WLB) policies and practices and subsequent challenges faced by Nigerian workers. The paper argues that institutions shape WLB practices (and policies), and thus, constitute WLB challenges. Design/methodology/approach – Relying on qualitative, interpretive approach, and the institution-based view of organizational practice, the study investigates the relationship between institutions, WLB practices/ policies, and subsequent challenges that female workers undergo, using 25 semi-structured interviews. Findings – The findings reveal Nigeria’s unique institutional context frames and foster challenges for female workers. Also, it was identified that institutional and sociocultural pressures on female employees demonstrate that consequent challenges, while common to female workers in other countries, are more intense and challenging in Nigeria because of its peculiar institutions and context. Research limitations/implications – This study offers an opportunity to unpick how institutions are important in understanding organizational practices as part of wider social structures, which influence organizational realities, including WLB. The qualitative, exploratory approach undertaken can limit generalizing the findings. Originality/value – This study contributes to the emerging concept of WLB discourse from the developing countries’ perspective. It also reveals how WLB discourse differs from nonwestern context and emphasizes previously identified challenges that female workers experience based onWLB practice. The study also sheds light on how institutions shape organizational practice.

Knowledge, Awareness and Practice with Antimicrobial Stewardship Programmes among Healthcare Providers in a Ghanaian Tertiary Hospital

: Antimicrobial resistance (AMR) is a significant problem in global health today, particularly in Low- and Middle-Income Countries (LMICs) where antimicrobial stewardship programmes are yet to be successfully implemented. We established a partnership between AMR pharmacists leads from a UK NHS hospital and in Ho Teaching Hospital with the aim to by enhance antimicrobial stewardship knowledge and practice among healthcare providers through an educational intervention. We employed a mixed method approach including an initial before and after training survey on knowledge and awareness, followed by qualitative interviews with healthcare providers conducted six months after delivery of training. This study was carried out in Ho teaching hospital with 18 healthcare professionals including pharmacists, medical doctors, nurses and medical laboratory scientists. Ethical approval was obtained prior to data collection. In the first phase, we surveyed 50 health care providers including nurses (33%), pharmacists (29%) and biomedical scientists (23%). Of these, 58% of participants had engaged in continuous professional development on AMR/AMS, and above 95% demonstrated good knowledge on the general use of antibiotics. A total of 18 participants, which included 4 medical doctors, 5 pharmacists, 4 nurses, 2 midwives and 3 biomedical scientists, were interviewed in the second stage and demonstrated greater awareness of AMS practices, particularly the role of education for patients as well as healthcare professionals. We found that knowledge and practice with AMS was markedly improved six months after the training session. There is limited practice of AMS in LMICs, however through AMR focused training we demonstrate improved AMS skills and practice among health care providers in Ho Teaching hospital. There is need for continuous AMR training sessions for health care professionals in resource limited settings.
Evaluation of Macular Vessels Density Changes in Patients with Primary Open Angle Glaucoma by Swept-source Optical Coherence Tomography Angiography

Primary open angle glaucoma (POAG) is an optic neuropathy that that is described by the dynamic deterioration and functional thinning of the optic nerve, including the optic disc, causing a dynamic decrease in visual sensitivity and in some people irreversible visual impairment,. In early phases, it disturbs the proximal retinal activity, specifically, the ganglion cells. It is well recognized that substantial ganglion cell damage can occur earlier to the visual field anomalies appear in the static automated perimetry [1].
Compact test platform for in-situ indentation and scratching inside a scanning electron microscope (SEM)

In-situ materials tests have the advantage to link visual and sensor based information during a dynamic experiment. In this thesis, a compact indenter-scratch test device has been built at EPFL-LSRO and installed inside a Scanning Electron Microscope (SEM) at EMPA-Thun. This indenter has been designed having high resolution and long-range stick-slip piezoelectric actuators to position and test the samples. The combination of the SEM high magnification / high depth of focus images and the high resolution positioning system has permitted to identify and test very particular regions of interest. The output of the test is an associated video/image sequence with the Load – Penetration depth (P × h) graph. The stick-slip actuator is a special type of inertial drive. Its working principle uses a stick phase (static friction) to drive and a quick redraw movement to create the slip phase (using dynamic friction). The movement is thus a sequence of 300-400nm steps. The drawback is an inherent backlash (from 30-100nm) and a microvibration after each slip phase. A rather low driving force (≈ N range) is another known limitation of stick-slip actuators. The first contribution of this thesis has been to evaluate the impact of using stick-slip actuators to realize indentation and scratching. For this, different materials have been tested with Cube Corner and Berkovich tips in two driving modes – continuous and stick-slip mode. The comparison has been realized visually (videos, pictures) and through the P × h graph. Scratch test has also been performed in these two driving modes, but has been limited to visual comparison only. Results during indentation have not shown perceptible differences in the P × h graphs nor in the image obtained in both modes. The P × h curve overlap has been mainly congruent in both driving modes. This has been assessed in Fused Silica, GaAs and Zn-BMG. However, a scratch in AlCu, Zr-BMG and in GaAs has revealed the presence of a visual pattern, which has been related to the actuator's slip phase. The results are discussed in the text. The second contribution is the optimization of stick-slip actuators. The goal was to obtain a given driving force with a minimum amount of jump-back. Various solutions have been proposed and then validated through simulations and experiments. A reduction of the jump-back size by factor of four has been achieved. This is considered to be the demonstration of the promising potentialities of the proposed methods. The work also includes a design guide for a SEM environment as well as an overview of several tests that have been made using the in-situ indenter. Examples apart from nanoindentation are surface patterning capability and micropillars compressions tests. The thesis has successfully demonstrated that stick-slip actuators can be an option to build compact and SEM compatible devices for material characterization, and especially for a SEM-indenter.

RESUMO: Os idosos constituem o grupo populacional que mais cresce de forma acelerada e descontrolada no Brasil, representando 14,3% da população geral. Associado a isto e ao aumento da expectativa de vida, mudança do padrão de adoecimento do pais e a medicalização no idoso, temas como a farmacologia do indivíduo idoso tornam-se essenciais na formação de um profissional da área da saúde. O processo normal do envelhecimento possui particularidades capazes de modificar as etapas da farmacocinética e a farmacodinâmica de um medicamento, predispondo o idoso às Reações Adversas a Medicamentos (RAM), cascata iatrogênica, uso de Medicamentos Potencialmente Inapropriados (MPI) e polifarmácia, processo do adoecimento, quedas e fraturas, delirium, hospitalização, institucionalização e até à morte. Baseado nisso, instrumentos ou listas de medicamentos considerados inadequados para uso em idosos foram criadas, cada uma com particularidades da comercialização de seu país. Visto isso, entende-se que o assunto é de extrema relevância na pratica clínica, e, quando utilizado de forma interdisciplinar, melhora a qualidade de serviços, formação de profissionais da área da saúde e permite a prevenção de eventos iatrogênicos.

Status of cell division, cytogenetical index, and chromosome details on the immature stage of Trichogramma brassicae (Hymenoptera: Trichogrammatidae)

Investigation of various tissues of immature stages Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) from Iran was examined in an attempt to determine its cell division. In addition, the Metaphase plate of the wasp is evaluated to elucidate its chromosome feature and asymmetry/ symmetry karyotype. We found that: 1) Brain tissue of prepupa and early hours of the pupa stage are the highest mitotic index (%) and metaphase index, 2) The number of haploid chromosomes of the wasp is n = 5, and 3) The karyotype of the wasp is almost symmetrical.
8.6fJ/step VCO-Based CT 2-Order ∆Σ ADC

A purely VCO-based continuous-time (CT), singleloop second-order ∆Σ ADC is proposed in this work. Two ring oscillators are used as integrators to perform second-order quantization noise shaping. The proposed CT ADC does not require additional circuit for excess loop delay compensation. A current-reuse DAC architecture is proposed to simultaneously reduce ADC noise and power consumption. A 65nm prototype consumes 105μW from 1V supply at sampling frequency of 32.6MHz, and achieves a walden FoM of 8.6fJ/step over 2.3MHz bandwidth, which is the best among current CT ∆Σ ADCs.
Unlocking the Potential of Ordinary Classifier: Class-specific Adversarial Erasing Framework for Weakly Supervised Semantic Segmentation

Weakly supervised semantic segmentation (WSSS) using image-level classification labels usually utilizes the Class Activation Maps (CAMs) to localize objects of interest in images. While pointing out that CAMs only highlight the most discriminative regions of the classes of interest, adversarial erasing (AE) methods have been proposed to further explore the less discriminative regions. In this paper, we review the potential of the pre-trained classifier which is trained on the raw images. We experimentally verify that the ordinary classifier1 already has the capability to activate the less discriminative regions if the most discriminative regions are erased to some extent. Based on that, we propose a class-specific AE-based framework that fully exploits the potential of an ordinary classifier. Our framework (1) adopts the ordinary classifier to notify the regions to be erased and (2) generates a class-specific mask for erasing by randomly sampling a single specific class to be erased (target class) among the existing classes on the image for obtaining more precise CAMs. Specifically, with the guidance of the ordinary classifier, the proposed CAMs Generation Network (CGNet) is enforced to generate a CAM of the target class while constraining the CAM not to intrude the object regions of the other classes. Along with the pseudo-labels refined from our CAMs, we achieve the state-of-the-art WSSS performance on both PASCAL VOC 2012 and MS-COCO dataset only with image-level supervision.

RELATION OF HOMOCYSTEINE AND FOLIC ACID IN CARCINOGENESIS- REVIEW WITH REVIEW OF LITERATURE

Oral cancer is the commonest cancer in India, accounting for 50–70% of total cancer mortality and accounts for highest incidence among Asian countries. It affects anterior tongue, cheek, floor of mouth, gingiva or any other part of the oral cavity. The incidence of Oral Squamous Cell Carcinoma (OSCC) is high in several countries. Furthermore, the intraoral location differs in different population groups. These observations in turn provide a pointer towards the etiological agents involved. As the oral cavity is easily accessible for visual examination, oral cancer can be detected at an early stage. Nevertheless, in many tropical countries, in most instances patients with this disease seek medical attention only at an advanced stage, leading to poor prognosis and postoperative disfigurement. OSCC can be defined “as a malignant epithelial neoplasm exhibiting squamous differentiation and characterized by the formation of keratin and/or the presence of intercellular bridges”. This is the most common malignant neoplasm of the oral cavity. Although it may occur at any intraoral site, certain sites are more frequently involved than others. The variation in the distribution of OSCC is due to the differences in clinical appearance, the nature of the lesion and particularly the prognosis.
Genomic signatures of speciation in butterflies

Studies of life rely on classifying organisms into species. Contrary to a frequent belief, simple and quantitative standards for species delineation are lacking, and debates about species delimitation create obstacles for conservation biology, agriculture, legislation, and education. To tackle this key biological question, we have chosen butterflies as model organisms. We sequenced and analyzed transcriptomes of 186 butterfly specimens representing pairs of close but clearly distinct species, conspecific populations, and taxa that are debated among experts. We find that species are robustly separated from conspecific populations by the combination of two measures computed on Z-linked genes: fixation index that detects hiatus between species, and the extent of gene flow that quantifies reproductive isolation. These criteria suggest that all 9 butterfly pairs that caused experts' disagreement are distinct species, not populations or subspecies. When applied to Homo, our criteria agree that all modern humans are the same species distinct from Neanderthals, suggesting relevance of this study beyond butterflies. Furthermore, we found that divergence and positive selection in proteins involved in interaction with DNA (including proteins encoded by trans-regulatory elements), circadian clock, pheromone sensing, development, and immune response recurrently correlate with speciation. A significant fraction of these divergent proteins is encoded by the Z chromosome, which appears to be more resistant to introgression than autosomes. Taken together, we find possible common speciation mechanisms in butterflies, present additional support for an important role of the Z chromosome in speciation of butterflies, and suggest quantitative criteria for butterfly species delimitation using genomic data, which is vital for the exploration of biodiversity.
