Demonstration of 1200 V/1.4 mΩ cm2 vertical GaN planar MOSFET fabricated by an all ion implantation process

We present a vertical GaN planar metal-oxide-semiconductor field-effect transistor (MOSFET) fabricated by an all ion implantation process. The fabricated MOSFET shows an on-resistance of 2.78 mΩ cm2 and a breakdown voltage of 1200 V, by applying the short cell pitch design to reduce the on-resistance and a Mg and N sequential implantation to improve the breakdown voltage of the pn-junction. By evaluating each on-resistance component in the fabricated vertical GaN planar MOSFET using the simultaneously formed test structures, an effective on-resistance of the active region excluding the source parasitic resistance is 1.4 mΩ cm2. Consequently, it was demonstrated that an all ion implantation process can fabricate a vertical GaN planar MOSFET with a high breakdown voltage and low on-resistance. This result will greatly contribute to the realization of GaN power devices.
Lowest of the low: why some countries suffer terrorist attacks against schools

ABSTRACT The purpose of this research was to investigate whether terrorist attacks against schools and other educational institutions were more common in states with little respect for human rights for a sample of 75 countries from 1981–2010 using the Global Terrorism Database. Specifically, we examined whether religious repression by governments, state terrorism against civilians and female political and economic empowerment would influence attacks against schools and terrorist attacks against any targets. We found that government oppression of religious expression was associated with increased terrorist attacks against educational targets and that some levels of government violence against its citizens was associated with both increased terrorist attacks against educational targets and, to a lesser degree, all targets. Greater political empowerment of women was associated with increased terrorist attacks against educational targets. On the contrary, increased economic rights for women was associated with some decreases in terrorist attacks against educational targets and to a lesser degree, against any type of target. We concluded that government behaviour at the state level can affect terrorist behaviour and targeting by terrorist individuals or organizations when governments manufacture grievance by denying civilians human rights, including rights to religious expression, safety and security, and political and economic rights for women.

The stem cell mobilizer StemEnhance reduces fibrosis and enhances proliferation in Thioacetamide induced-liver cirrhosis in the adult male albino rat

StemEnhance (SE) is a haematopoietic stem cell mobilizer deduced from natural planet products. Preclinical studies showed that SE advances cardiovascular muscle recovery and relieves the symptoms and signs of diabetes. However, the efficacy of SE in improving liver cirrhosis has not been investigated. This study was done to assess the helpful effects of SE in a Thioacetamide (TAA)-induced rodent model of liver cirrhosis. Thirty adult male albino rats, 16∼18 weeks old and 210∼240 gm weight, were used in this study. They were divided equally into three groups: 1. normal control group: received saline intraperitoneal injection (i.p.) twice weekly for 12 weeks and served as a control; 2. cirrhosis group: liver cirrhosis was induced by (i.p.) injection of TAA (200 mg/kg body weight) twice a week for 8 weeks and left untreated; 3. cirrhosis/SE group: liver cirrhosis was induced the same way and then treated daily orally with SE at a dose of 300 mg/kg body weight dissolved in distilled water for 4 weeks. All the studied groups were sacrificed 12 weeks after beginning experiments. SE was found to alleviate hepatic fibrosis, improve histopathological changes and enhance hepatocyte proliferation. In addition, TNF-α mRNA expression was down-regulated in TAA-induced cirrhotic livers after SE administration. We conclude that SE has a beneficial role in relieving liver fibrosis and improving liver function in the rat model of liver cirrhosis.
Hoë voorkomskoers van bakteriële vaginose en Chlamydia in ’n lae-inkomste, hoë-bevolkingsdigtheid gemeenskap in Kaapstad

Jong Suid-Afrikaanse vroue uit hulpbron-arm gemeenskappe staar verskeie uitdagings in die gesig in terme van hul seksuele en reproduktiewe gesondheid. Hier beskryf ons die voorkoms van vaginale mikrobiota en seksueel oordraagbare infeksies (SOI’s) onder 102 16–22-jarige MIV-negatiewe Suid-Afrikaanse vroue uit ’n lae-inkomste, hoe-bevolkingsdigtheid gemeenskap in Kaapstad (K). Vaginale mikrobiota is met behulp van 16S rRNA amplikon volgorde-bepaling geprofileer; bakteriese vaginose (BV) status is met behulp van ’n Nugent-telling vasgestel; en SOI’s is deur middel van ’n multipleks polimerase kettingreaksie bepaal. SOI’s was algemeen, met 55% van die vroue wat ten minste een SOI gehad het; 41% wat met hoe-risiko menslike papillomavirus (MPV) besmet was, en ’n verdere 28% wat met laerisiko-MPV besmet was; 44% van die vroue was met Chlamydia besmet, waarvan 16% een of meer addisionele SOI gehad het. BV persentasies was ook baie hoog, met 55% van die vroue wat as BV-positief (Nugent-telling ≥7) geklassifiseer is, 7% as BV-intermedier (Nugent-telling 3–6), en 38% as BV-negatief (Nugent-telling 0–2). Streptococcus (Streptococcus agalactiae), die grootste oorsaak van neonatale sepsis, was teenwoordig in 25% van die BV-positiewe vroue en 28% van die BV-negatiewe vroue, en was dus meer onder BV-negatiewe vroue. Beide Chlamydia-infeksie en BV kan reproduktiewe gesondheid nadelig beinvloed en verhoog hierdie vroue se risiko vir die verkryging van MIV. Die voorkoms van veral Prevotella amnii kan die MIV-risiko verhoog as gevolg van sy inflammatoriese kapasiteit. Laboratorium-gebaseerde toetsing vir SOI’s (veral Chlamydia en Gonorrhoeae) blyk in hierdie gemeenskap geregverdig te wees, tesame met verdere monitering en/of behandeling van BV.
Dynamic and Stability Analysis of the Power System With the Control Loop of Inverter Air Conditioners

The power consumption of inverter air conditioners (IACs) can be regulated flexibly by adjusting the compressor's operating frequency, which has been proven suitable for providing regulation capacities to power systems. Considering the rapid phasing out of traditional generating units, massive IACs create huge alternative regulation potential. However, the impact of IACs on the power system's stability is rarely studied. To address this issue, this article proposes the modeling and control methods of IACs to provide regulation capacities to power systems. On this basis, a novel power system model with the control loop of large-scale IACs is developed, where the communication latency during the control signal transfer process is also considered. Then, the dynamic performance and steady-state errors of the novel power system are evaluated, showing that IACs can quickly participate in and smoothly withdraw from the regulation process. Furthermore, the stabilities and sensitivities of power systems with and without IACs are compared, in order to illustrate that both the stability margin and robustness of the power system can be increased via the control loop of IACs. Finally, the effectiveness of the proposed models and methods are verified by numerical studies.
Polymer-based hybrid nanoparticles for bioapplications

In dieser Arbeit wurden drei verschiedene Konzepte fur den zielgerichteten Transport von Wirkstoffpartikelsystemen untersucht. Diese Ansatze sollten zur Entwicklung von Strategien beitragen, die eine Anwendung dieser zielgerichteten Wirkstofftransporter in der Therapie ermoglichen und konnen zudem zu einem besseren Verstandnis ihrer Wirkungsweise nach ihrer Aufnahme in Zellen beitragen. Dieses setzt voraus, dass sowohl die Aufnahmeprozesse als auch die zellularen Strukturen, ihre Integritat, Membran-Nanopartikel-Wechselwirkungen und Veranderungen der zellularen Strukturen nach der Aufnahme der Wirkstoffnanopartikel untersucht werden konnen. Die verwendeten Systeme basieren auf kolloidalen Goldnanopartikeln, die mit geeigneten Zielgruppen ausgestattet werden konnen. Dabei dienten insbesondere transmissionselektronenmikroskopische Untersuchungen dazu, ihre Wirk ungs weise auf zellulare Systeme zu studieren. In diesem Zusammenhang bietet die Verwendung von kolloidalen Goldnanopartikeln die Moglichkeit, sogar einzelne Nanopartikel in Zellen zu visualisieren. Damit sind sie, im Gegensatz zu polymerbasierten Nanopartikelsystemen, einfach zu identifizieren, wobei jedoch auch angemerkt werden muss, dass polymerbasierte Nanopartikel generell eine grosere Bandbreite von Moglichkeiten bieten, die Eigenschaften der Wirkstofftransportsysteme einzustellen. Dieses bezieht sich vornehmlich auf ihre Grose, ihre Form und die Moglichkeit funktionelle Einheiten einzubauen, die z.B. auf ausere Veranderungen reagieren. Dazu zahlen z.B. funktionelle Gruppen, die auf Anderungen der Temperatur oder des pH-Wertes reagieren. Letzteres ist ein wichtiger Aspekt bei der Entwicklung von Konzepten, die eine gesteuerte Wirkstoffabgabe verfolgen.
Deaths of Despair or Drug Problems?

The United States is in the midst of a fatal drug epidemic. This study uses data from the Multiple Cause of Death Files to examine the extent to which increases in county-level drug mortality rates from 1999-2015 are due to “deaths of despair”, measured here by deterioration in medium-run economic conditions, or if they instead are more likely to reflect changes in the “drug environment” in ways that present differential risks to population subgroups. A primary finding is that counties experiencing relative economic decline did experience higher growth in drug mortality than those with more robust growth, but the relationship is weak and mostly explained by confounding factors. In the preferred estimates, changes in economic conditions account for less than one-tenth of the rise in drug and opioid-involved mortality rates. The contribution of economic factors is even less when accounting for plausible selection on unobservables, with even a small amount of remaining confounding factors being sufficient to entirely eliminate the relationship. These results suggest that the “deaths of despair” framing, while provocative, is unlikely to explain the main sources of the fatal drug epidemic and that efforts to improve economic conditions in distressed locations, while desirable for other reasons, are not likely to yield significant reductions in drug mortality. Conversely, the risk of drug deaths varies systematically over time across population subgroups in ways that are consistent with an important role for the public health environment related to the availability and cost of drugs. Put succinctly, the fatal overdose epidemic is likely to primarily reflect drug problems rather than deaths of despair.
AI-Enabled Sub-6-GHz and mm-Wave Hybrid Communications: Considerations for Use With Future HSR Wireless Systems

Due to abundant spectrum resources, communications in the millimeter-wave (mm-wave) bands have been widely considered as the key enabler for next-generation wireless systems, including future high-speed railway (HSR) wireless systems, to dramatically increase data rates. To overcome the hostile propagation properties of mm-wave bands, antenna arrays, which enable directional transmissions with extended transmission distance, become essential techniques. Nevertheless, the high cost of antenna arrays and the limited battery lifetime of user equipment are slowing down the practical deployment of mm-wave communications. Without these limitations, an HSR scenario is better suited for mm-wave communications. However, the point-like coverage of mmwave directional beams cannot provide robust access for high-mobility scenarios.
Prediction prices of basrah light oil using artificial neural networks

The global economy is assured to be very sensitive to the volatility of the oil market. The beneficial from oil prices collapse are both consumers and developed countries. Iraq economy is a one-sided economy which is completely depends on oil revenue to charge the economic activity. Hence, the current decline in oil prices will produce serious concerns. Some factors stopped most investment projects, rationalize the recurrent outflow, and decrease the development of economic activity. The study of forecast oil prices is considered among the most complex studies because of the different dynamic variables that affects the strategic goods. Moreover, the laws of economics controlling the prices of oil such as the supply and demand law. Some other variables that control the oil prices are the political conditions when these conditions contribute to the world production. The subject of forecasting has been extremely developing during recent years and some modern methods have been appeared in this regards, for example, Artificial Neural Networks. In this study, an artificial neural network (FFNN) is adopted to extract the complex relationships among divergent parameters that have the abilities to predict oil prices serving as an inputs to the network data collected in this research represent monthly time series data are Oil prices series in (US dollars) over a period of 11 years (2008–2018) in Iraq
Visual detection of Cu(II) ions in water environment using gold nanoparticles modified with methanobactin

A Mb-functionalized AuNPs system for copper ion detection based on coordination chemistry of Mb and copper ion to mediate the assembly of Mb-functionalized gold nanoparticles was presented. Mb-functionalized AuNPs solution was stable in red color. While the presence of Cu2+ induces significant assembly of Mb-functionalized AuNPs by forming Mb2-Cu coordination along with red-to wine red-to-purple-to-blue colour changes. The solution color was related to the assembly degree of Mb-functionalized AuNPs. Meanwhile, good linear relationship of Cu2+ along with A 645 nm/525 nm values could be obtained for its quantitative determination. Furthermore, Mb-functionalized AuNPs system shows excellent selectivity to Cu2+ against any other tested metal ions and anions, and good sensitivity with LOD of 3.26 nmol/L for real water samples.
Seasonal Variation of Potential Source Locations of Atmospheric Particulates over the Indo-Gangetic Plain of India

Ambient particulate matter (PM2.5 and PM10) concentrations were measured during two different seasons (summer and winter) at three different locations of Gurugram which is located in the Indo-Gangetic plain of India. The ambient concentrations of both PM2.5 and PM10 were higher during winter season (PM2.5: 261 μg·m-3; PM10: 440 μg·m-3) when compared to summer period (PM2.5: 114 μg·m-3; PM10: 202 μg·m-3). Potential Source Contribution Function (PSCF) analysis suggests significant seasonal variation in potential contributing locations of ambient PM2.5 over the study area. The PSCF analysis suggests that cross country transport of PM2.5 from Pakistan and Afghanistan significantly attributed to higher concentrations of PM2.5 at the study locations; whereas, PM2.5 emitted from locations in the south-western direction of the study sites attributed to the ambient PM2.5 concentrations at the study site during summer seasons. Further study is required to measure percentage contribution from different sectors and locations to the ambient particulate concentrations at the study site to develop sector specific mitigation plan.

PENGEMBANGAN MEDIA PEMBELAJARAN BERBASIS VIRTUAL REALITY UNTUK MENINGKATKAN HASIL BELAJAR PESERTA DIDIK SEKOLAH DASAR

Educators use various methods to explain the material so that learning objectives can be achieved, one of the methods is by utilizing learning media. The purpose of using learning media in learning activities is to facilitate communication and learning. The use of media in learning activities aims to attract the attention of students and strengthen their concentration when receiving material from educators. The development of virtual reality media is an effort to realize educational goals. One of the success of learning lies in the ability of students' learning outcomes. Learning outcomes are very important for students as a benchmark of the extent to which students understand the material delivered by educators. Virtual reality media make learning outcomes the basis of development. The purpose of this study is to produce products in the form of virtual reality media to improve learning outcomes of elementary school students.This research is a development research with 4D development model from Thiagarajan.

Working the aporia: ethnography, embodiment and the ethnographic self

A more considered sense of the embodied nature of encounter is called for in the scholarship of ethnography. This paper argues for an ethnographic practice that accordingly moves beyond simplistic recounts of ‘highly personalised styles and their self-absorbed mandates’ (Van Maanen, 2011: 73), to more fully position an understanding of the ethnographer’s Self as an also encountered ‘site’. Taking cues from Heideggar’s (2008/1927) formulation of Dasein and the realisation of the Self through the encountered Other, this paper argues that attempts to make sense of the Other in ethnography – ultimately the raison d’etre of ethnographic practice – concomitantly require an accounting-for of the Self. This paper takes aim at the nature of embodiment as central to the experience of encounter, but will argue that this encounter of the Self functions as an aporia: a site of unknowing, but equally, of generative possibility. It is with the effects that embodiment has and the inflections it provides for the ethnography that particular attention is given.
Fijian infrastructural citizenship: spaces of electricity sharing and informal power grids in an informal settlement

Abstract Infrastructure has historically been absent in informal settlements in Oceania. Oceanic governments have deliberately withheld infrastructure to these settlements denying them essential resources, human rights, and ways of life. Current reforms in urban policy seek to rectify this record by promising more inclusive infrastructures. In this article, I investigate the effect a promised electricity infrastructure had in an informal settlement in Suva, Fiji. Prior to development, residents created their own infrastructures that equitably shared electricity in spaces of electricity sharing. The initiation of infrastructural works destroyed this local infrastructure embedded in local social relations. While residents waited for this promised infrastructure to be constructed, they erected informal power grids that mimicked the exclusive and commoditised provision of electricity of the planned infrastructure. I argue that the promise of infrastructural development in informal settlements in Oceania is reshaping previously inclusive forms infrastructural citizenship in favour of more exclusive infrastructural relationships.
Approach and potentiality of low level laser therapy in veterinary medicine

The Low Level Laser Therapy (LLLT) is an innovative and increasing therapeutic technique in Veterinary Medicine. As in Human Medicine, the low power red/near-infrared laser light could be used to reduce inflammatory conditions, induce analgesia and promote damaged tissues repair, both in conventional animals like horses, dogs and cats and in unconventional ones, including reptiles, birds and exotic mammals. Since A.Eistein (1917) and E.Mester (1968) built its physical and biochemical fundamentals, a growing number of researches, over the years, have expanded the knowledge of the molecular process considered today at the basis of the macroscopic therapeutic effects. Producing a photochemical tissue interaction, laser light is absorbed by the mitochondrial respiratory chain stimulating the generation of ATP, ROS and NO; this determines a modulation in gene expression of proteins playing key roles in cellular processes as tissue repair, inflammatory response and pain control. Different animal pathological conditions could significantly benefit from this therapy, such as acute/chronic muscle-skeletal disorders, dental afflictions, dermatitis, otitis, stomatitis and different kind of skin lesions, as traumatic or post-operative ones. Furthermore, other significant applications are developing scientifically: the treatment of internal organ diseases, the regenerative effects on nervous tissue and the possibility of a beneficial cell-specific cytotoxicity, relevant for oncological cases, are some of these. A high-quality research is therefore crucial for this quickly expanding field of Veterinary Medicine, in order to find the most effective protocols and the ideal doses for each pathological conditions, aiming to always ensure the best and up-todate animal care.
Toracoscopia en el manejo del empiema en niños

The main complication of bacterial pneumonia in children is the paraneumonic effusion (40%) and a prevalence of empyema is reported in 2% of cases. The management of this pathology in the pediatric population is controversial, being described from the management with antibiotic therapy, drainage with chest tube, fibrinolysis, thoracotomy and video-assisted thoracoscopy.Objective: To describe the initial experience in the management of empyema in children by video-assisted thoracoscopy in the Hospital Infantil San Vicente Foundation.Methods: Retrospective study with pediatric patients undergoing video-assisted thoracoscopy for the management of empyema from August 2013 to November 2015. Using a medical history reviewResults: Eighteen children underwent video-assisted thoracoscopy for the management of empyema, mean age 37 months. Ten male patients; average clinical presentation of 10 days, mean of hospitalization of 21 days. The procedure had an average duration of 117 minutes. Management failure was considered in 3 patients and the average duration of the chest tube was 8 days.Conclusions: Video-assisted thoracoscopy is a safe and useful procedure in the management of children with empyema, with low complication rates. It should be compared with studies that evaluate the medical management of this pathology in order to create algorithms for treatment of empyema in our children's hospital.
