The study addresses the integration of the Building Information Modelling (BIM) methodology with Virtual Reality (VR) and Augmented Reality (AR) technologies in the context of the development of a multidisciplinary project, involving architecture, structures, water network and electrical system components. In order to cover in detail the various design features, the case study was limited to a specific area of a house, the sanitary rooms, as it presents sufficient complexity in modeling and the application of VR and AR software. The VR/AR functionalities applied over the BIM model increase the potential of BIM in the construction sector, contributing to the achievement of a high level of collaboration and control of the project based on an immersive and interactive environment. The elaboration of the different phases of a BIM design requires the transfer of models between BIM and VR/AR systems, allowing us to analyze the main advantages that BIM/VR/AR integration can introduce in the construction industry. The study contributes positively to achieving new knowledge in BIM, being disseminated in an academic research work and illustrated in a practical context.

The centre of Bioethics Faculty of Medicine University of Porto Porto Portugal

Objective: sexual violence affects women of all ages but, more commonly, children and adolescents. This study aimed to identify the extent to which services are being provided at the hospitals responsible for the emergency care of children and adolescents who have suffered sexual violence and to determine whether there is any difference in the provision of such services as a function of the victim’s age. Method: This cross-sectional study investigated differences in the care received by female children and adolescents who are victims of sexual violence in a capital city, comparing the treatment given to girls under 15 with that given to adolescents of 15 to 19 years of age. The data were extracted from the state Department of Health database between 01/01/2012 and 31/12/2016. Results: children under 15 were much less likely to receive prophylaxis against HIV, sexually transmitted infections and hepatitis B, with the number of adolescent girls treated adequately corresponding to between twice and almost three times the number of children treated prophylactically. Only 10% of girls under 15 received emergency contraception. conclusion: The lack of standard care established by the Ministry of Health highlights the need for urgent debates both locally and probably throughout the country, as the situation may be similar in other regions of the country.

氢气是一种清洁能源,利用太阳能进行光催化分解水产氢,因为节能和环保,吸引了国内外学者的广泛关注.但是,半导体光催化材料普遍存在可见光吸收范围窄和光生载流子易复合等问题,导致光催化效率不高.半导体耦合是拓展光吸收范围,并促进光生载流子空间分离的有效策略之一.能带相互交错的两种半导体复合,可以形成传统的Ⅱ型异质结,但是这种耦合方式削弱了光生电荷的氧化还原能力.相对传统Ⅱ型异质结光催化材料的不足,余家国教授提出了s型异质结的概念,它通常由两种n型半导体光催化剂组成,其中能带位置较高的为还原型光催化剂(RP),能带位置较低的是氧化型光催化剂(OP).形成s型异质结的关键是接触界面处存在由RP指向OP的内电场.受内建电场的驱动,s型异质结界面电子和空穴的流向与传统Ⅱ型光催化剂完全不同.由于保留了光生电子和空穴具有较强的还原和氧化能力,s型异质结在热力学上更有利于光催化氧化与还原反应.本文以硫代乙酰胺为硫源,采用低温溶剂热法(乙二醇中110℃反应2 h),在氧化型光催化剂(1D的WO_(3)纳米棒)表面原位生长还原型光催化剂(2D的ZnIn_(2)s_(4)纳米片),从而构建具有3D结构的s型异质结,并进行可见光催化分解水产氢性能研究.ZnIn_(2)s_(4)在WO_(3)纳米棒表面的原位生长,有利于复合半导体界面的电荷传输,同时增加光催化反应的活性位点.而且具有3D结构的光催化材料,有利于光散射而增强光吸收,增强光催化活性.研究结果表明,优化的ZnIn_(2)s_(4)/WO_(3)复合光催化材料(ZIs-2.5/W)可见光(λ>400 nm)分解水产氢速率高达300μmol·g^(–1)·h^(–1),分别是单一组分WO_(3)和ZnIn_(2)s_(4)分解水产氢速率的417和2倍.复合催化剂在400 nm处分解水产氢的光量子效率为2.81%.通过原位X射线光电子能谱和(开尔文探针)功函测定,并结合贵金属的光化学表面沉积实验,推测出光生电子在ZnIn_(2)s_(4)和WO_(3)复合界面处的s型传输机制,该s型异质结不仅促进了载流子分离,而且保留了复合催化剂强的氧化与还原性能,因而显著提高可见光光催化分解水产氢性能.

精心设计的异质结光催化剂已经被证明能够有效地促进电荷转移,从而实现特定的迁移路径和长的载流子寿命,这在进一步提高性能方面具有巨大的潜力.然而,传统二元异质结光催化剂的光催化性能仍然受到其较低的载流子分离效率的影响.本文报道了一种通过原位面对面生长直接合成双Ⅱ型snO_(2)@Zns-ZHs(ZHs=Znsn(OH)_(6))三元异质结的策略.基于可靠的实验和理论计算,揭示了双Ⅱ型snO_(2)@ZnsZHs的载流子动力学提升机制.snO_(2)的光生空穴(h+)能够分别迁移到ZHs和Zns的价带,确保了snO_(2)@Zns-ZHs可以保持双氧化电位来产生足够的羟基自由基(·OH)参与NO氧化反应.这种独特的双Ⅱ型snO_(2)@Zns-ZHs三元结构在光照30 min后对NO去除率高达44.5%,活性分别是ZHs的23.5倍、snO_(2)的29.7倍和Zns的15.9倍.光催化活性提升与独特的双Ⅱ型反应机理反映了snO_(2)@Zns-ZHs异质结构的优势,本工作有望为三元异质结的设计提供可行的思路.
