Authors: Động Nguyễn Duy 
Published: October 2018

Bài báo này tập trung phân tích những ưu điểm nổi trội và ứng dụng của bơm nhiệt trong công trình. Theo đó hệ số hiệu suất của bơm nhiệt cao hơn nhiều so với máy lạnh thông thường; ngoài khả năng làm lạnh và sưởi ẩm, bơm nhiệt còn có khả năng đun và cấp nước nóng cho sinh hoạt. Bài báo còn tập trung tính toán, phân tích đánh giá và so sánh hiệu quả kinh tế, xã hội cho một công trình khách sạn khi sử dụng hệ thống bơm nhiệt đun nước nóng kết hợp điều hòa không khí trung tâm (phương án 1) so với hai trường hợp khác là sử dụng bơm nhiệt (phương án 2) và điều hòa trung tâm kết hợp bình đun điện trở (phương án 3). Kết quả cho thấy, phương án 2 có tuổi thọ cao nhất lên đến 20 năm, đồng thời việc vận hành và bảo trì, bảo dưỡng, thay thế đơn giản thuận tiện hơn phương án 1 và 3. Tuy nhiên, việc sử dụng phương án 1 chi phí đầu tư đứng thứ 2 (khoảng 2,6 tỷ đồng), nhưng sau 10 năm tổng chi phí tiền điện chỉ là 278 triệu thấp hơn nhiều so với hai phương án còn lại (phương án 2 - 430 triệu, phương án 3 - 1,2 tỷ đồng). Như vậy, phương án 3 không sử dụng bơm nhiệt thì có chi phí điện năng cao nhất, nên được thay thế bằng phương án có sử dụng bơm nhiệt.

ROLE OF METFORMIN ON CLOZAPINE INDUCED DYSLIPIDAEMIA IN WISTAR RATS
Authors: Md Hussaini Syed Shoib , Naikwadi Akram A , VU Narsapur 
Published: October 2018

Background: The clinical research in past decade has reported that most second-generation antipsychotics (SGAs) can cause serious metabolic derangement, which substantially increases the risk for type II diabetes mellitus. Several retrospective studies have shown increased in serum triglyceride in patients treated with Clozapine. SGAs induced metabolic syndrome is characterized by weight gain, hyperglycaemia, hypertension, hyperlipidaemia, glucose intolerance and insulin resistance. Metformin is currently used to treat metabolic syndrome and type II diabetes mellitus. It is therefore important to determine whether Metformin is efficacious in treating Clozapine-induced metabolic derangement like dyslipidaemia. Objectives: To evaluate the effect of Metformin in minimizing Clozapine induced metabolic derangement like dyslipidaemia. Methodology: Wistar rats weighing 180-240g either sex were divided into 3 groups of 6 rats each. Group 1 served as control, Group 2 Treated with Clozapine 25mg/kg body weight and Group 3 Treated with Clozapine 25mg + Metformin 100mg/kg body weight for 28 days P.O. Group 2 and group 3 were treated for 28 days. Biochemical investigations: Retro-orbital blood was collected for Lipid profile. Result: Lipid profile of group 2 rats treated with Clozapine showed dyslipidaemia (TG 103.3 ±1.7mg/dl, Tc 113.7 ±1.6mg/dl). Whereas group 3 rats treated with Clozapine 25mg + Metformin showed normal lipid levels (TG 94.7±1.7mg/dl, TC 102.8 ±0.8 mg/dl) comparable to group 1(TG 93.0 ±2.6mg/dl, TC 103.7 ±1.5mg/dl). Conclusion: This study exploring the use of Metformin to prevent metabolic derangement like dyslipidaemias in patients of schizophrenia treated with Clozapine.

Group ORAM for privacy and access control in outsourced personal records

Published: October 2018

Cloud storage has rapidly become a cornerstone of many IT infrastructures, constituting a seamless solution for the backup, synchronization, and sharing of large amounts of data. Putting user data in the direct control of cloud service providers, however, raises security and privacy concerns related to the integrity of outsourced data, the accidental or intentional leakage of sensitive information, the profiling of user activities and so on. Furthermore, even if the cloud provider is trusted, users having access to outsourced files might be malicious and misbehave. These concerns are particularly serious in sensitive applications like personal health records and credit score systems. To tackle this problem, we present [Formula: see text], a definitional framework for Group Oblivious RAM, in which we formalize several security and privacy properties such as secrecy, integrity, anonymity, and obliviousness. [Formula: see text] allows per entry access control, as selected by the data owner. [Formula: see text] is the first framework to define such a wide range of security and privacy properties for outsourced storage. Regarding obliviousness, we tackle two different attacker models: our first definition protects against an honest-but-curious server while our second definition protects against such a server colluding with malicious clients. In the latter model, we prove a server-side computational lower bound of [Formula: see text] where n is the number of entries in the database, i.e., every operations requires to process a constant fraction of the database. Furthermore, we present two constructions: a pure cryptographic instantiation, which achieves an [Formula: see text] amortized communication and computation complexity and a construction based on a trusted proxy with logarithmic communication and server-side computational complexity. The second construction bypasses the previously established lower bound leveraging a trusted party. Both schemes achieve secrecy, integrity, and obliviousness with respect to a server colluding with malicious clients, but not anonymity due to the deployed access control mechanism. In the former model, we present a cryptographic system that achieves secrecy, integrity, obliviousness, and anonymity. In the process of designing an efficient construction, we developed three new, generally applicable cryptographic schemes, namely, batched zero-knowledge proof of shuffle correctness, the hash-and-proof paradigm, which even improves upon the former, and an accountability technique based on chameleon signatures, which we consider of independent interest. We implemented our constructions in Amazon Elastic Compute Cloud (EC2) and ran a performance evaluation demonstrating the scalability and efficiency of our construction.
A 3-month mastication intervention improves recognition memory
Authors: Kim Curie , Miquel Sophie , Thuret Sandrine 
Published: October 2018

BACKGROUND: Decreased mastication due to edentulism in both humans and animals have a negative impact on brain function and cognition. Human populations have shown a close association between masticatory function, cognitive status and age-related neurodegeneration in the elderly. Evidence shows that mastication during tasks may have an acute positive impact on normal cognitive function, such as sustained attention. However, there is a lack of evidence showing the long-term effects of changes in habitual masticatory behaviour on cognition. OBJECTIVE: To investigate the impact of a 3-month mastication intervention on cognitive function in healthy older adults. METHODS: 53 participants aged 45–70 years old were required to chew mint-flavoured sugar free chewing gum for 10 minutes, 3 times a day over 3 months. Pattern separation and recognition memory was measured using the Mnemonic Similarity Task. Questionnaires were administered to measure changes in mood, anxiety, and sleep quality. RESULTS: Extended periods of mastication gave rise to a significant improvement in recognition memory compared to a non-chewing control group. CONCLUSION: With an ageing population, non-medical interventions are imperative to delay age-related cognitive decline. Further work needs to be carried out in larger populations to validate the findings in this study and elucidate potential mechanisms.

The Effectiveness of Saskatoon's Bicycle Boulevard
Authors: Surkan Daniel Gordon 
Published: October 2018

Saskatoon, like many cities, is attempting to diversify the transportation options available to its citizens and take advantage of the benefits that urban cycling provides through an increased investment in bicycle infrastructure. The recent development of a bicycle boulevard, a street that gives priority to cyclists over motor traffic, is an example of Saskatoon’s shift. This study examines the effectiveness of Saskatoon’s bicycle boulevard by taking an inventory of bicycle infrastructure on this route, measuring demographic information of boulevard users, performing traffic counts, and conducting intercept surveys of boulevard users. This data was analyzed through the lens of National Association of City Transportation Officials (NACTO) boulevard design standards. The data gathered from these methods indicates that Saskatoon’s boulevard is successful in some areas and needing improvement in others. While the boulevard appears to be successfully address design considerations relating to signage/pavement markings, route planning, and traffic speeds, the City has been less successful in managing traffic volumes and dealing with areas where cyclists must compete with motorists for road space. This study recommends that Saskatoon install motorist volume control measures at key areas of perceived danger throughout the boulevard to increase its effectiveness. Repaving the street and tackling perceptions of crime in the area were additional recommendations based on the findings of this study.

Broken Windows Theory: Time to Reevaluate and Reform a Failing Ideology with the Help of Communities
Authors: Schappert Prairie Violet Pauline 
Published: October 2018

Broken windows theory is a predominant concept that is used to influence policing and legislation enforcement. In today’s society, the use of such force and regulation is now being questioned due to the harm and negative effect which has created the marginalization and criminalization of the poor and homeless. Claiming communities as broken window areas through social and physical disorder leads to stigmatization through invasive police force tactics. Broken windows theory and policing must be reformed and reevaluated to facility community growth and responsibility to care for citizens. The introduction of community oriented policing into neighbours is the beginning of aiding police through citizen interaction and building social cohesion.
The Impact of Oral Health on Systemic Health: Current Challenges and Future Prospective

Published: October 2018

Oral pathology is a broad topic, but this article will focus on the oral conditions that have an established or accepted relationship with systemic health: caries and the periodontal disease-gingivitis and periodontitis. Dental caries is probably the most common infectious disease across humanity. Primary anticipation of disease is the best move toward but often difficult to achieve. From a primary care point of view, it is vital that physicians and dentists augment collaboration and share in sequence that can impact the patient’s health. Optimization of patients’ physical condition is the aim of both the medical and dental professions.

Carlos Casares e a literatura infantil
Authors: Senín Francisco Xavier 
Published: October 2018

A literatura infantil e xuvenil galega débelle moito a Carlos Casares. El foi creador dos primeiros libros en galego para os nenos (A galiña azul ou As laranxas máis laranxas de todas as laranxas). Como tradutor, verqueu ao galego non poucos títulos doutras linguas, entre eles obras de Maria Gripe e, sobre todo, O principiño. De por parte, como editor, no tempo no que dirixiu a Editorial Galaxia o seu traballo supuxo un pulo importante para a literatura dirixida aos pequenos; a el débenselle coleccións como Árbore, Sete mares ou Costa Oeste. Casares era unha persoa divertida que procuraba tecer redes con persoas que traballaban no mundo da edición. A través destes contactos nas feiras internacionais do libro estaba ao tanto do que se publicaba noutros lugares.

Abstract
The Giant Southern Stream (GSS) of M31, a keystone signature of a major accretion event, yields crucial constraints on M31 formation and evolution models. Currently, our understanding of the GSS, in terms of both its geometry and its chemistry, results from either wide-field imaging probing only a few magnitudes below the red giant branch tip, or deep imaging or spectroscopy of isolated regions. Here, we take an alternative approach, using Hubble Space Telescope (HST) imaging to characterize the horizontal branch red clump (RC) using unbinned maximum likelihood fits to luminosity functions from observed color–magnitude diagrams. Comparing the RC mean magnitude across three fields at projected distances of 21, 52, and 80 kpc from M31, we find a line-of-sight distance gradient identical to recent literature measurements in fields along the core. We also find tentative evidence that the line-of-sight distance dispersion increases with projected distance from M31. Meanwhile, the metallicity in the 52 kpc field westward of the GSS core is at least as high as that in the 21 kpc GSS core field, and the peak colors of the RC in these two fields imply identical metallicities to within 0.2 dex. We discuss implications for distance and metallicity gradients both along and perpendicular to the GSS in the context of recent ground-based photometric and spectroscopic results, including evidence for a dropoff in metallicity moving westward from the GSS, as well as prospects for further constraining stellar populations in the vicinity of the GSS.
Designing for deep learning in the context of digital and social media
Authors: Gee James-Paul , Esteban-Guitart Moisés 
Published: October 2018

There is today a great deal of controversy over digital and social media. Even leaders in the tech industry are beginning to decry the time young people spend on smartphones and social networks. Recently, the World Health Organization proposed adding “gaming disorder” to its official list of diseases, defining it as a pattern of gaming behavior so severe that it takes “precedence over other life interests”. At the same time, many others have celebrated the positive properties of video games, social media, and social networks. This paper argues that a deeper understanding of human beings is needed to design for deep learning. For the purposes of this study “design for deep learning” means helping people matter and find meaning in ways that make them and others healthy in mind and body, while improving the state of the world for all living things, with due respect for truth, sensation, happiness, imagination, individuality, diversity, and the future. In particular, fifteen features related to human nature are suggested based on recent scientific developments to answer the question: What is a human being? Consequently, proposals that are linked to learning and transformation, as well as social improvement, should fit with the ways in which humans, as specific sorts of biological and social creatures, learn best (or can learn at all) and can change for the better.
En la actualidad existe una nutrida controversia en relación a los medios de comunicación sociales y digitales que ha llevado, incluso, a censurar la utilización de las redes sociales y los móviles por parte de líderes en la industria tecnológica. En este sentido, la Organización Mundial para la Salud ha propuesto añadir el «desorden del juego» a su listado de enfermedades, definiéndolo como un modelo de comportamiento de juego tan severo que se impone como «preferencia sobre otros intereses». Al mismo tiempo, distintos académicos han enfatizado los aspectos positivos derivados de las redes sociales y los videojuegos. En este artículo se argumenta que es necesaria una mejor comprensión del ser humano para poder implementar lo que aquí se define como diseño para el aprendizaje profundo. El «diseño para el aprendizaje profundo» está encaminado al reconocimiento de las personas y el desarrollo de sentidos saludables, individual y colectivamente, así como la mejora, en general, del estado del mundo para todos los seres vivos, según principios de verdad, felicidad, imaginación, individualidad, diversidad y futuro. En particular, se sugieren quince características basadas en desarrollos científicos que responden a la pregunta: ¿Qué es un ser humano? Consecuentemente, propuestas vinculadas al aprendizaje y la transformación y mejora social deben ser coherentes con dichas características que permiten definir cómo las personas, en tanto que organismos biológicos y sociales, aprenden o pueden aprender óptimamente, así como cambiar para mejorar.
Type 2 Innate Lymphoid Cells Impede IL-33–Mediated Tumor Suppression

Abstract
Although a number of studies have recently explored the contribution of the adaptive immunity in IL-33–mediated antitumor effects, innate immune involvement has been poorly characterized. Utilizing Rag1−/− mice (lacking T and B lymphocytes), we show in this study that either systemic administration of recombinant IL-33 or ectopic expression of IL-33 in melanoma cells is sufficient to inhibit tumor growth independent of adaptive antitumor immunity. We have demonstrated that IL-33–mediated antitumor effects depend on expansion and activation of NK cells. Interestingly, IL-33 also promoted the expansion of active type 2 innate lymphoid cells (ILC2s) via its receptor, ST2, which in turn inhibited NK activation and cytotoxicity. This IL-33–induced ILC2 activity coincided with greater expression of the immunosuppressive ectoenzyme CD73. Removal of CD73 from ILC2s in culture with NK cells resulted in markedly increased activation levels in NK cells, offering a potential mechanism by which ILC2s might suppress NK cell–mediated tumor killing. Thus, our data reveal an important contribution of IL-33–induced ILC2 to tumor growth by weakening NK cell activation and tumor killing, regardless of adaptive immunity.
