Authors: Perinha Andreia , Nogueira Catarina , Umbelino Cláudia , Silva Ana Maria , Cunha Eugénia , Curate Francisco 
Published: December 2018

A osteoporose é uma patologia metabólica óssea com maior incidência nas mulheres pós-menopáusicas e nas camadas mais idosas das populações atuais. Caracteriza-se pelo decréscimo da massa e da resistência ósseas, com aumento subsequente do risco de fratura. No presente trabalho, propõe-se, como objetivo principal, a compreensão dos padrões epidemiológicos da perda de massa óssea cortical numa amostra de indivíduos pertencente à Coleção de Esqueletos Identificados do século XXI (CEI/XXI) e da sua relação com as fraturas de fragilidade. Foram analisados 136 indivíduos {F = 68; M= 68} pertencentes à CEI/XXI. Para a avaliação da perda de massa óssea procedeu-se análise radiogramétrica do 2.º metacárpico. Verificou-se também a presença/ausência de fraturas de fragilidade (anca, úmero proximal, rádio distal e corpo vertebral). Os resultados obtidos sugerem que a perda de massa óssea está intimamente relacionada com o envelhecimento, sobretudo no sexo feminino. As fraturas de fragilidade são mais comuns nos indivíduos femininos e a idade aparenta serum fator de risco para a sua ocorrência, contrariamente ao que acontece nos indivíduos masculinos.
Model of the Galaxy with Hot Dark Matter
Authors: Khokhlov Dmitri L. 
Published: December 2018

Abstract
The model of the galaxy is considered as a structure of the baryonic matter embedded into the hot dark matter. The dark matter is supposed to come into being from the decaying matter after the epoch of structure formation. The galaxy is divided into two regions. In the inner region, the baryonic matter predominates over the hot dark matter while in the outer region, the hot dark matter predominates over the baryonic matter. The motion of the test particle is bounded in the inner region (elliptic orbit) and unbounded in the outer region (parabolic orbit). Observational constraints on the proposed model are considered from the rotation curves of the galaxies: Milky Way, M33, NGC 2366 and IC 2574.

Autonomy in surgical robots and its meaningful human control
Authors: Ficuciello Fanny , Tamburrini Guglielmo , Arezzo Alberto , Villani Luigi , Siciliano Bruno 
Published: December 2018

Abstract
This article focuses on ethical issues raised by increasing levels of autonomy for surgical robots. These ethical issues are explored mainly by reference to state-ofart case studies and imminent advances in Minimally Invasive Surgery (MIS) and Microsurgery. In both area, surgicalworkspace is limited and the required precision is high. For this reason, increasing levels of robotic autonomy can make a significant difference there, and ethically justified control sharing between humans and robots must be introduced. In particular, from a responsibility and accountability perspective suitable policies for theMeaningfulHuman Control (MHC) of increasingly autonomous surgical robots are proposed. It is highlighted how MHC should be modulated in accordance with various levels of autonomy for MIS and Microsurgery robots. Moreover, finer MHC distinctions are introduced to deal with contextual conditions concerning e.g. soft or rigid anatomical environments.

Authors: Vahabi Seyed Milad , Zafarghandi Mojtaba Shamsaie , Bahreinipour Mostean 
Published: December 2018

Abstract
The attenuation coefficient is an important parameter to describe the penetration of photons in biological materials, such as vitamins. In this study, a novel simulation model based on the Monte Carlo simulation has been utilized to calculate the mass attenuation coefficients for some vitamins at the energies 356.61, 661.66, 1,250, and 1,408.01 keV. The calculated attenuation coefficient values were then used to determine the mass energy absorption coefficient. It was observed that the parameters were highly in accordance with the XCOM program and experimental data. The results showed that the model is quite convenient in the calculation of mass attenuation coefficients. Besides, the Monte Carlo simulation can be followed to determine the attenuation of photons in various materials. The results of the investigated data are useful in the medical field.

Authors: He Guiyuan , Li Qi , Li Wenxin , Wang Li , Yang Jun , Zeng Fanju 
Published: December 2018

Objective: The aim of this study was to determine whether N-acetylcysteine (NAC) has an effect on acute kidney injury (AKI) in chronic kidney disease patients undergoing cardiac surgery.
Methods: We reviewed literature through PubMed, Medline through PubMed and OVID, The Cochrane Library, Wan Fang Database, China Biology Medicine Database, Chinese Periodical Database, China Knowledge Resource Integrated Database, and Chinese Clinical Trial Registry (1980 to July 10, 2018). Two investigators independently collected the data and assessed the quality of each study. RevMan 5.3 was used for the present metaanalysis.
Results: A total of 5 RCTs (N = 678 participants) were included in the primary analysis. Pooled analysis showed that intravenous infusion of NAC significantly reduced the incidence of AKI (RR = 0.77, 95% = 0.63 to 0.94, P < .01) and that NAC could decrease the adverse cardiac events (RR = 0.83, 95% = 0.70 to 0.97, P < .05), but that it may increase the length of stay in the ICU (mean difference [MD] = 2.1, 95% CI = 1.61 to 2.60, P < .01). There were no statistically significant differences between the 2 groups in the requirement for renal replacement therapy(RRT) (RR = 1.33, 95% = 0.63 to 2.81, P = .45) and all-cause mortality (RR = 0.51, 95% = 0.25 to 1.06, P = .07).
Conclusion: Our study shows that intravenous infusion of NAC could prevent postoperative AKI in preexisting-renal-failure patients undergoing cardiac surgery.
Effects of flavonol quercetin on activity of lipid peroxide oxidation in experimental bacterial-immune periodontitis
Authors: Demkovych Andrii 
Published: December 2018

The article presents the results of lipid peroxidation activity in blood serum, which were assessed on the base changes in the level of oxidative modification of proteins, TBA-active products, and total amount of nitrogen (II) oxide metabolites (NO2− + NO3−). Indices were determined on the 14th day of development in experimental periodontitis both without correction, and in condition treatment with a water-soluble flavonol quercetin (corvitin). The treated animals take intramuscular injections of corvitin in a dose 100 mg/kg weight for 7 days. For further testing, blood serum was selected. The results were statistically analyzed using parametric and non-parametric indices. In this investigation, characterized dynamics of changes in the indices of oxidative processes activity were revealed both during the period of formation and the course of periodontitis. In particular, it was found that, for the period of the most expressed inflammatory reaction in the periodontal complex, intensive increase in the level of reactive forms of oxygen. The treatment with flavonol quercetin for 7 days resulted in stabilization of free radical processes and the suppression of the inflammatory reaction.

The duration and intensity of exercise are significant factors in oxidative, morphological, and functional changes of the gastrointestinal tract. This study aimed to investigate the effects of both exhaustive swimming and probiotic VSL#3 on rats that had been previously trained with moderate swimming. The rats were divided into four groups labeled: control (C), probiotic (P), exercise (E), and probiotic–exercise (PE). Groups P and PE were fed with probiotic mixture VSL#3. Groups E and PE had a 5-week moderate swimming program (1 h/day for 5 days/week), followed by a 1-week exhaustive swimming program (trained like in moderate program but 3 times with 150 min resting sessions, for 5 days/week). At the end of the program, the rats were euthanized. Malondialdehyde, superoxide dismutase, catalase, and reduced glutathione levels were measured in tissue samples from the gastrocnemius muscle, heart, liver, kidney, and colon. In vitro contractile activity and histomorphology of the colon were also determined. Exercise and/or probiotic decreased the oxidative stress and also increased the level of one or more of the antioxidant enzymes in some of the organs. Probiotics had more pronounced effects on colon morphology than exercise but unexpectedly this effect was non-trophic. In the colon, the thickness of the tunica muscularis and the number of goblet cells were not affected; however, probiotic administration decreased the crypt depth and tunica mucosa thickness. Exercise increased the Emax value of acetylcholine (ACh), while decreased its sensitivity. These findings suggest that exhaustive swimming does not cause oxidative stress and that probiotic consumption improves oxidative balance in trained rats. The probiotic intake does not alter the effect of exercise on the contractile activity of the colon. Colon mucosal changes induced by probiotics are independent of exercise.

Library as one of the supporting units in college must provide good services to its customers. Therefore, a library must comply with the laws, regulations, and standards that have been made. Three institutions creating the standards of college libraries for improving the services are Standar Nasional Indonesia (SNI), Perpustakaan Nasional Republik Indonesia (PNRI), and Direktorat Jendral Pendidikan Tinggi (DIKTI). Among those three institutions, PNRI should be as a reference since its assessment has the most details. Politeknik Negeri Bandung (Polban) as higher education that has been established for more than 20 years should meet PNRI standard. This study used the descriptive method to describe the condition of the library associated with the nine components in the accreditation guidelines which are Service, Cooperation, Collection, Organization of Library Material, Human Resources, Infrastructure Building/Room, Budget, Library Management, and Library Collection Care. The data was obtained through interviews, observation based on nine components of PNRI standard, and document analysis with the solutions. The results from this research show that Polban Library has met the two components of the nine components that are Organization of Library Material and Library Collection Care. This is because the library has implemented its activities in accordance with the guidance of the University Library Accreditation Standard set by National Library of Indonesia (SNI). Meanwhile, the other seven components have not been met yet by Polban. They need to be fixed and adjusted to the prevailing standards.
İlköğretim Anabilim Dalı Doktora Tezlerinde Kullanılan Başarı Testlerinin İncelenmesi (2012-2017)

Bu araştırmanın amacı,
İlköğretim anabilim dalı bünyesinde gerçekleştirilen doktora tezlerinde
kullanılan başarı testlerinin, başarı testi geliştirme adımlarına uygunluğunu
incelemektir. Araştırma, analitik araştırma modeline göre desenlenmiştir. Bu
bağlamda İlköğretim anabilim dalında 2012-2017 yılları arasında
gerçekleştirilen, veri toplama aracı olarak başarı testi kullanılan ve
erişimine izin verilen 67 doktora tezine YÖKTEZ veri tabanından ulaşılmıştır.
Bu tezlerde yer alan başarı testleri; alanyazın taraması, madde havuzu,
belirtke tablosu, uzman görüşü, kapsam geçerliği çalışmaları, pilot uygulama,
madde analizleri (ayırt edicilik, güçlük) ve güvenirlik değerlerinin yer aldığı
araştırmacı tarafından geliştirilen bir kontrol listesi yardımıyla incelenmiştir.
Araştırmada elde edilen veriler ile ilgili olarak belirlenen kategoriler
üzerinden sayısallaştırma gerçekleştirilerek betimsel istatistiki teknikler ile
analiz yapılmıştır. Araştırma kapsamında toplam 62 doktora tezinde ölçme aracı
olarak kullanılan başarı testleri incelenmiştir. İnceleme sonucunda başarı
testi geliştirmenin her aşamasında yetersizlikler olduğu sonucuna ulaşılmıştır.
Bu yetersizlikler en çok hazırlık aşamasında belirtke tablolarının
hazırlanmasında (%66,1), uygulama aşamasında uzman görüşü alma (%53,2) ve kapsam geçerliği çalışmalarında
(%88,7) görülmektedir. Başarı testi geliştirme sürecinin son basamağı olan
analiz aşamasında ise eksikliklerin diğer aşamalara göre az olması dikkati
çeken bir bulgudur. Her bir aşamanın yeterli düzeyde olduğu başarı testi
sayısının sadece 3 (%4,8) olması tezlerde kullanılan başarı testlerinin
istenilen niteliğe sahip olmadığını göstermektedir. Araştırmadan elde edilen
bulgular doğrultusunda bazı önerilerde bulunulmuştur.

Published: December 2018

This paper analyzes the current factors causing an energy crisis, including depletion of the natural resources, geopolitical tensions, energy security, search for climate stability and absence of universal access to energy. Through the deductive method, the study analyzes if investments are considered as a possible solution to promote sustainable energy. It assesses the current position of intergovernmental organizations linked in some way to the topic of energy, such as the WTO, ECT, G8, G20, IEF, IEA and OPEC, to identify whether the initiatives are being developed and the political will to do so. Some organizations are connected but with limited and insufficient focus. Funding initiatives are below of what is necessary to achieve the goals considered relevant. In the absence of a global governance of energy due to the lack of sufficient cooperation and collaboration of international actors to efficiently mitigate the energy crisis. The challenge is to alter from high to low carbon economy, and the shift from fossil fuels to renewable energy will contribute substantially to this transition. It concludes the necessity of cooperation between organizations such as IRENA and ONU’s programme Sustainable Energy for All, which have the potential to become catalysts for a new trend.
