Abstract
In this work, the effect of sintering parameters on electronic structure and physical properties of yttria-partially stabilized ZrO2 (YPSZ) commercial ceramics has been studied using the central composite design (CCD) method. The CCD method allows using empirical modelling with better fitting, by considering the interaction between both factors. Different temperature ranges and sintering times for processing of YPSZ ceramics have been used in order to evaluate the grain growth, hardness and volumetric shrinkage by the CCD method. X-ray diffraction patterns and Rietveld refinement data indicate that non-sintered YPSZ ceramics exhibits two phases related to tetragonal and monoclinic structures, while the sintered YPSZ ceramics exhibits a single phase related to a tetragonal structure. Moreover, the monoclinic structure presents zirconium (Zr) atoms coordinated to seven oxygen (O) atoms, while in the tetragonal structure Zr atoms are coordinated to eight O atoms. Field emission scanning electron microscopy images were employed to monitor the sintering and growth process. In addition, the response surfaces obtained from calculations presented the effect of thermal and kinetic variables on the physical properties such as average grain size, volumetric shrinkage and hardness of YPSZ ceramics.

Case report. Cystic lesions of the maxilla – clinical considerations and differential diagnosis
Authors: Lapusneanu Lucian , Radulescu Marlena , Arhire Adrian , Filip Andreea 
Published: May 2017

Abstract
Cystic lesions of the maxilla are benign entities with both odontogenic and non-odontogenic origins. The maxillary cyst is a benign tumor of the bones of the jaw, which has a membrane and contains a fluid, semi-solid or mixed (liquid / semi-gaseous) material. These often lead to deformities in the jaw area. Cases are specific by framing pathological rarity, etiology, pathogenesis and clinical symptoms.
Considering the large entity of cystic formations that can be found in the maxilla region, we selected two patients with cystic formations of the upper jaw, which were part of different pathological etiology categories, with special rarity occurring, evolutionary appearance and difficult to classify in terms of pathognomonic signs.

Die richtige Mischung? Ein randomisiertes Experiment zur Datenqualität bei der Kombination von Telefon- und Onlineerhebung in der empirischen Sozialforschung
Authors: Krug Gerhard , Carstensen Johann , Kriwy Peter 
Published: May 2017

Zusammenfassung:
Der Beitrag untersucht die Datenqualität einer kombinierten Telefon- und Onlinebefragung. Solche Mixed-Mode-Designs werden in der deutschen akademischen Sozialforschung noch relativ selten eingesetzt, obwohl damit eine Reihe von Vorteilen verbunden sein kann. Allerdings können sich auch negative Effekte aus einer Kombination von Daten aus verschiedenen Quellen ergeben. Im Rahmen eines randomisierten Experimentes werden eine Single-Mode-Telefonbefragung und eine Mixed-Mode-Telefon-/Onlinebefragung hinsichtlich mehrerer Indikatoren der Datenqualität untersucht. Vorteilhafte Effekte zeigt die Mixed-Mode-Erhebung bezüglich einer erhöhten Responserate. Zudem liegen die soziodemographischen Merkmale der Befragten näher an der Grundgesamtheit und Antworten auf sensitive Fragen weisen geringere Messfehler auf. Andererseits erhöht sich die Antwortverweigerung, allerdings nur unter sehr spezifischen (und vermeidbaren) Bedingungen.
20 Years of the Croatian Capital Market
Authors: Šeba Mihaela Grubišić 
Published: May 2017

Abstract
From 1990s to the end of 2006 there have been two stock exchanges in Croatia - an official stock exchange in Zagreb and a so-called alternative capital market in Varaždin. The Zagreb stock exchange had a dominant role in the Western Balkan region until 2008, when its market capitalisation significantly decreased because of the influence of the global financial crisis and the economic downturn of the country. This paper analyses gradual regulatory and institutional development of the Croatian capital market, emergence and strengthening of institutional investors and assets under their management, key market development indicators related to market supply and demand and investor protection mechanisms. The research presented in this paper has shown the crucial role of regulation in attracting investors and sustaining their presence in the market. It also recommends more active role of regulation and stock exchange towards the issuers and small investors to encourage constant supply of corporate securities.

Published: May 2017

Abstract
The main objective of this research paper is to examine whether the practice of corporate governance (CG) measured by the CGI-Crobank® index is significant for the explanation of variations in the performance of Croatian banks measured by the return on assets, return on equity, interest margin, margin of non-interest income, operating expenses margin, and by Tobin’s Q for the observed period from 2011 to 2015. The research is made on Croatian banks that form the CGI-Crobank® index using the data and information from annual questionnaires of CG codex, primarily to ensure objectivity, standardization and comparability. The goal of the literature analysis was to show present findings in the areas of corporate reporting and its impact on CG. Results obtained in the research indicate that a well implemented practice of corporate governance measured by the CGI-Crobank® index have influence on the variations in the performance of Croatian banks measured by Tobin’s Q and financial indicators.
Autocatalytic and Non-Catalytic Oxidation of Manganese(II) on a Platinum Electrode in Acetic Buffer
Authors: Tikhonov Konstantin G. 
Published: May 2017

Abstract
The influence of acetate on Mn2+ oxidation by a platinum electrode has been investigated in aqueous solution with cyclic voltammetry. It is found that acetate at concentrations below 0.5 M gives rise to autocatalytic oxidation of Mn2+ with MnO2 serving as the catalyst, while in 0.5–1 M acetate (as well as in the absence of acetate) Mn2+ is oxidized non-catalytically. The autocatalytic oxidation is revealed by a separate voltammetric wave which has a much sharper rise and a lower potential compared to non-catalytic waves, by a sigmoid kinetics during chronoamperometry and by an enhanced Mn2+ uptake with electrodeposited MnO2. The increase in temperature and Mn2+ concentration promotes autocatalysis while acidification and the increase in sweep rate inhibits it that is thought to be due to the acceleration or delay of MnO2 formation from Mn3+. It is suggested that acetate acts in two ways: (1) thermodynamically stabilizes Mn3+ by complexation to enable the autocatalytic reaction Mn2++MnO2+OAc−+H+↔Mn3+−OAc+ MnIIIOOH and (2) delays the formation of MnO2 (presumably on the stage of Mn(III) crystallization) which leads to the inhibition of autocatalysis at high acetate concentrations.

Published: May 2017

AbstractThe demonstration of the ability of rodents to navigate in virtual reality (VR) has made it an important behavioral paradigm for studying spatially modulated neuronal activity in these animals. However, their behavior in such simulated environments remains poorly understood. Here, we show that encoding and retrieval of goal location memory in mice head-fixed in VR depends on the postsynaptic scaffolding protein Shank2 and the dorsal hippocampus. In our newly developed virtual cued goal location task, a head-fixed mouse moves from one end of a virtual linear track to seek rewards given at a target location along the track. The mouse needs to visually recognize the target location and stay there for a short period of time to receive the reward. Transient pharmacological blockade of fast glutamatergic synaptic transmission in the dorsal hippocampus dramatically and reversibly impaired performance of this task. Encoding and updating of virtual cued goal location memory was impaired in mice deficient in the postsynaptic scaffolding protein Shank2, a mouse model of autism that exhibits impaired spatial learning in a real environment. These results highlight the crucial roles of the dorsal hippocampus and postsynaptic protein complexes in spatial learning and navigation in VR.

Authors: Chatzittofis Andreas , Savard Josephine , Arver Stefan , Öberg Katarina Görts , Hallberg Jonas , Nordström Peter , Jokinen Jussi 
Published: May 2017

Background and aims
There are significant gaps in knowledge regarding the role of childhood adversity, interpersonal violence, and suicidal behavior in hypersexual disorder (HD). The aim of this study was to investigate interpersonal violence in hypersexual men compared with healthy volunteers and the experience of violence in relation to suicidal behavior.

Methods
This case–control study includes 67 male patients with HD and 40 healthy male volunteers. The Childhood Trauma Questionnaire – Short Form (CTQ-SF) and the Karolinska Interpersonal Violence Scale (KIVS) were used for assessing early life adversity and interpersonal violence in childhood and in adult life. Suicidal behavior (attempts and ideation) was assessed with the Mini-International Neuropsychiatric Interview (version 6.0) and the Montgomery–Åsberg Depression Rating Scale – Self-rating.

Results
Hypersexual men reported more exposure to violence in childhood and more violent behavior as adults compared with healthy volunteers. Suicide attempters (n = 8, 12%) reported higher KIVS total score, more used violence as a child, more exposure to violence as an adult as well as higher score on CTQ-SF subscale measuring sexual abuse (SA) compared with hypersexual men without suicide attempt.

Discussion
Hypersexuality was associated with interpersonal violence with higher total scores in patients with a history of suicide attempt. The KIVS subscale exposure to interpersonal violence as a child was validated using the CTQ-SF but can be complemented with questions focusing on SA for full assessment of early life adversity.

Conclusion
Childhood adversity is an important factor in HD and interpersonal violence might be related to suicidal behavior in hypersexual men.
The Emerging Role of Histone Demethylases in Renal Cell Carcinoma
Authors: Guo Xiaoqiang , Zhang Qiaoxia 
Published: May 2017

Renal cell carcinoma (RCC), the most common kidney cancer, is responsible for more than 100,000 deaths per year worldwide. The molecular mechanism of RCC is poorly understood. Many studies have indicated that epigenetic changes such as DNA methylation, noncoding RNAs, and histone modifications are central to the pathogenesis of cancer. Histone demethylases (KDMs) play a central role in histone modifications. There is emerging evidence that KDMs such as KDM3A, KDM5C, KDM6A, and KDM6B play important roles in RCC. The available literature suggests that KDMs could promote RCC development and progression via hypoxia-mediated angiogenesis pathways. Small-molecule inhibitors of KDMs are being developed and used in preclinical studies; however, their clinical relevance is yet to be established. In this mini review, we summarize our current knowledge on the putative role of histone demethylases in RCC.
Oratio: A Non-Lawyer's Views on the Revised White Paper on Arts, Culture and Heritage of 2013
Authors: Van Graan Mike 
Published: May 2017

The South African Department of Arts and Culture (DAC) recently published for comments a Revised White Paper on Arts, Culture and Heritage (the White Paper) dated 4 June 2013.[1] The White Paper contains a new vision of arts and culture and is intended to replace the existing White Paper on Arts, Culture and Heritage dated 4 June 1996 (the 1996 White Paper).[2] The publication of a revised white paper on cultural matters after 17 years is definitely not unwelcome but in this case a number of issues which need to be raised come to the fore.

Werknemers as Lasgewende Ouers in Surrogasie-Aangeleenthede: Die Geboorte van nuwe Verlof-behoeftes in Suid-Afrika / Employees as Commissioning Parents in Surrogacy Matters: The Birth of New Leave Requirements in South Africa
Authors: Botes Anri , Fourie Laetitia 
Published: May 2017

Commissioning parents, in terms of a surrogacy agreement, have the same parental obligations towards their child as traditional parents. Yet, despite the legitimising of surrogacy in the Children’s Act 38 of 2005, no provision has been made for suitable parental leave to be granted to these persons so that they may fulfil their parental obligations. The only leave that is currently available to commissioning parents is three days family responsibility leave in terms of section 27 of the Basic Conditions of Employment Act 75 of 1997 (BCEA). It is submitted that this leave is insufficient. In MIA v State Information Technology Agency 2015 36 ILJ 1905 (LC), the Labour Court indicated that amendments to labour legislation are necessary to address the lacuna in this respect. The Labour Laws Amendment Bill of 2015 has since proposed relevant amendments to such leave in terms of the BCEA. While the amendments are welcomed, the proposed period and management of the different types of leave give rise to concern and should be addressed. The latest developments in the United Kingdom in the field of parental leave make it a worthy comparator to provide guidelines for the improvement of the abovementioned Bill. In so doing, South African law can also sufficiently protect the interests of the parties to a surrogacy agreement, including the child born in terms thereof.
Lasgewende ouers ingevolge ŉ surrogasie ooreenkoms beskik oor dieselfde ouerlike verpligtinge as tradisionele ouers teenoor hulle kind. Alhoewel dit waar is, word sedert die statutêre erkenning van surrogasie in die Kinderwet nog geen geskikte ouerskapverlof vir hierdie persone gebied om aan sodanige ouerlike verpligtinge te voldoen nie. Die enigste verlof tans tot lasgewende ouers se beskikking is drie dae gesinsverantwoordelikheidsverlof ingevolge artikel 27 van die Wet op Basiese Diensvoorwaardes 75 van 1997 (WBDV). Dit word aan die hand gedoen dat hierdie verlof onvoldoende is. In MIA v State Information Technology Agency 2015 36 ILJ 1905 (LC) het die Arbeidshof aangetoon dat wysigings in hierdie verband aan die arbeidswetgewing noodsaaklik is ten einde die betrokke leemte aan te spreek. Die Labour Laws Amendment Bill van 2015 het sedertdien relevante wysigings aan verlof tot die WBDV voorgestel. Terwyl die vermelde wysigings verwelkom word, is die periodes en die bestuur van die verskillende tipes voorgestelde verlof kommerwekkend en behoort dit aangespreek te word. Die resente regsontwikkeling in die Verenigde Koninkryk op hierdie gebied kan as ŉ waardevolle vergelykende maatstaf dien ten einde riglyne vir die verbetering van bogenoemde konsepwet te bied. Sodoende kan ook die Suid-Afrikaanse reg die belange van die partye tot ŉ surrogaatooreenkoms, insluitende die van die kind daaruit gebore, na behore beskerm
Study of blood pressure profile and anthropometry in children belonging to low socio-economic status; a prospective cross sectional study
Authors: Sudhakar Chidambram , Rahman Raisur 
Published: May 2017

Background: A significant number of population in India are below poverty line. It contributes to the higher incidence of malnutrition especially among children which is 48% according to NFHS-3 (National family Health survey). Blood Pressure tracking studies suggest that hypertension in adulthood often has its origin in childhood. Blood pressure in childhood is the best predictor of hypertension in later life. There have been very few studies on malnutrition and Hypertension association and none in this area. One rationale for screening for hypertension in children and adolescents is that early identification of primary hypertension could lead to interventions to reduce blood pressure during childhood and adolescence, resulting in a reduced risk for cardiovascular events and death in adulthood.Methods: The present cross sectional prospective study was conducted on School going children (5-14 years) belonging to lower socio-economic status attending schools from Bhilai, DistrictDurg Chhattisgarh, India, within 5 km range of Chandulal Chandrakar Memorial Hospital over a period of 12 months from March 2015 to February 2016.The present study took 300 sample size. List of schools was arranged from district education officer (DEO) and required government schools were shortlisted on within 5 km range of hospital. After short history and examination, as per the prerequisite of proforma, the following measurements were taken. For all the statistical analysis MS EXCEL and SPSS 16 (Statistical Package for Social Science) version were used. The information collected was tabulated and the data was analyzed using suitable statistics.Results: 60% of the subjects were belongs to 5-10 years of age and 40% in 10-14 years’ age group. Males and females were equal in distributions (50% each), thus there were 150 males and 150 females in the current study. Overall prevalence of malnutrition in our study was 38.6%. The present study found 88 subjects (29.3%) having grade 1 malnutrition and 28 subjects (38.7%) having grade 2 and 0 (0%) with grade 3 and grade 4 malnutrition. There were 2 pre-hypertensives in our study, out of which one was male and one female. When analyzed according to nutritional status, there were 2 hypertensives in malnourished group. Similarly. there was 1 hypertensive in normal nutritional status group.Conclusions: There is a significant prevalence of malnutrition in our society which contributes to a more number of problems than what is presented to practicing paediatricians. The prevalence is higher in children <5 years age group overall which continues through school age and adolescent age group as shown in our study. The focus of attention should be identification of various diseases along with hypertension at the earliest and prevention of malnutrition.

Authors: Uprimny Yepes Miguel Antonio 
Published: May 2017

Colombia vive un proceso de transición demográfica moderada. Las personas hoy se enferman de padecimientos crónicos, presentan pluripatología, sufren de polimedicación, soledad y desarraigo. La prevalencia de personas en situación de discapacidad permanente es significativamente alta con pérdida de su autonomía de manera aguda o crónica significativos, que requieren de cuidados, apoyos y ayudas técnicas que se surten de manera formal o informal para recobrarla o minimizar la dependencia. Las personas adultas mayores con dependencia, las que padecen enfermedad crónica o un episodio agudo incapacitante, las que padecen de algún grado de discapacidad, las que se encuentran en fase terminal y sus cuidadores son entre otros, los sujetos de estos cuidados. Centros Día, transporte especial, cuidadoras, cuidados domiciliarios, teleasistencia, son algunos que deben articularse con salud como parte de la integralidad. Las personas que son objeto de la atención sociosanitaria son en las que confluye una necesidad de servicios sociales y de salud.
