Reuse of Spanish civil war air-raid shelters in Alicante: the R46 Balmis and R31 Seneca shelter

More than a hundred public air-raid shelters were constructed beneath Alicante during the Spanish Civil war. Their architectural uniqueness and humanitarian purpose render these shelters a tangible testament to our recent history. The Alicante Municipal Archives hold reports written by technicians who inspected the shelters in the 1940s, which were subsequently included in the Special Plan for public shelters in 1953. Half a century later, in 2003, information on the air-raid shelters was included in another Special Plan aimed at protecting Alicante’s archaeological heritage. Thanks to the work of the Municipal Heritage Conservation unit (COPHIAM) and the Special Protection Plan for Urban Archaeology (PEPA), the exact or approximate locations were identified for almost 90% of the shelters known to have existed. This paper describes interventions in two of these architectural spaces using advanced museology techniques. The first concerns air-raid shelter R46, located in the Plaza del Dr. Balmis in the city centre. This was built in 1938, and is rectangular with two entrances. The second is air-raid shelter R31, located in the Plaza Séneca.

A lesson in costs recovery

In La Spina v Macdonnells Law [2014] QSC 44 the Queensland Court of Appeal set aside a judgment entered in circumstances where the appellant had not been given the requisite notice of the application under r31 of the Uniform Civil Procedure Rules 1999 (Qld)(UCPR). The court found there had been a denial of natural justice. The court also considered whether in any event the entry of judgment in the circumstances was a proper exercise of the powers which may be exercised on an application for directions under r743H of the UCPR.

印度人群线粒体 DNA 系统发育基因组学研究

人类线粒体DNA(mtDNA)是一个长度16,569bp 的环状分子，编码13 种蛋白 质、22 种tRNA 和2 种rRNA。由于mtDNA 全基因组信息具有缺乏重组、母系 遗传、高突变速率和相对较高的分辨率等特点，近年来已经成为重建人类历史的 重要工具。这些研究已经证实，mtDNA 最古老的六个单倍型类群，L0-L5，在非 洲特异的出现；而6-7 万年前从L3 衍生出的M 和N 两个超类群最终占领了世界 其他地区。然而，mtDNA 全序列研究在世界上某些特定地区尚是一片空白，其 中之一便是作为人类“走出非洲”的关键区域——印度。 为弥补这一空白，我们从 1200 个印度样品中选择了131 个可以代表所有主 要单倍型类群的个体，进行了全基因组扩增和测序，手工重建并软件验证了系统 发育关系树。我们的结果发现了12 个新的印度特有单倍型类群(N5, R7, R8, R30, R31, M34-M40)，修订了11 个已知特有单倍型类群(N1d, R5, R6, U2a, U2b, U2c, M2, M4, M5, M6, M30)的定义，详细描述了存在于印度的欧洲特有类群(HV, JT, U, N1, W)。 这一工作产生了多个推论。第一个是关于人类“走出非洲”假说长期以来 存在的争论。欧亚大陆和大洋洲mtDNA 在M 和N(包括R)超类群系统发育关系 上星状和不重叠的分布，表明了人类走出非洲是沿着亚洲海岸线(即所谓的“南 方路线”)的一个快速扩散的过程。第二个推论是关于存在于印度的欧洲特有世 系。与典型的欧洲世系相比，这些世系仅仅存在一到两个突变，从而证实了新石 器时代以来来自于近东新月地带或中亚高原的基因流。第三个推论涉及一个早期 的印度全序列研究。仔细分析其数据表明，他们的数据丢失了很多基部的特有突 变并产生了多个幻影突变，从而证实了系统发育思想对检测数据质量的作用。 随着印度人群 mtDNA 全序列研究的完成，人类mtDNA 系统发育的基本框 架得以建立。人类mtDNA 明显地呈现出大洲特异性分布。目前已经有两种假说用来解释这一现象。传统的观点把这一现象归于遗传漂变；而近期的选择假说认 为选择在人类mtDNA 的分化中扮演了极其重要的角色，而气候是主要的选择压 力。为解决这一争论，我们收集了来自南亚、大洋洲和东亚三个具有不同气候的 地区的mtDNA，使用直接计数的办法比较了各个大洲之间同义突变和异义突变 的差异。结果表明，几乎在所有的基因中，异义突变的数量低于同义突变的数量， 从而表明纯净化选择是人类mtDNA 进化中的主要力量。然而，在这三个大洲之 间没有发现显著的差异，表明mtDNA 在这三个区域上所承受的选择压力基本相 同。这一结果表明，气候不大可能是造成人类mtDNA 分化的主要原因。

Wurtzite-to-tetragonal structure phase transformation and size effect in ZnO nanorods

The deformation of [0001]-oriented ZnO nanorods with hexagonal cross sections under uniaxial tensile loading is analyzed through molecular statistical thermodynamics (MST) simulations. The focus is on the size dependence of mechanical behavior in ZnO nanorods with diameters ranging from 1.95 to 17.5 nm. An irreversible phase transformation from the wurtzite (P6(3)mc space group) structure to a tetragonal structure (P4(2)/mnm space group) occurs during the tensile loading process. Young's modulus before the transformation demonstrates a size dependence consistent with what is observed in experiments. A stronger size dependence of response is seen after the transformation and is attributed to the polycrystalline nature of the transformed structure. A comparison of the MST and molecular dynamics (MD) methods shows that MST is 60 times faster than MD and yields results consistent with the results of MD.

Surface transformation and inversion domain boundaries in gallium nitride nanorods

Phase transformation and subdomain structure in [0001]-oriented gallium nitride (GaN) nanorods of different sizes are studied using molecular dynamics simulations. The analysis concerns the structure of GaN nanorods at 300 K without external loading. Calculations show that a transformation from wurtzite to a tetragonal structure occurs along {0110} lateral surfaces, leading to the formation of a six-sided columnar inversion domain boundary (IDB) in the [0001] direction of the nanorods. This structural configuration is similar to the IDB structure observed experimentally in GaN epitaxial layers. The transformation is significantly dependent on the size of the nanorods.

High-order harmonics of 248.6-nm KrF laser from helium and neon ions

We report high harmonic generation from a 248.6-nm KrF laser giving harmonic orders up to the 37th (67 Angstrom) in a helium gas jet and the 35th (71 Angstrom) in neon, for laser intensities up to 4 x 10(17) W/cm(2) in 380-fs pulses. These observations are interpreted using theoretical modeling that identifies the ion species He+, Ne+, and Ne2+ as the sources of the highest harmonics.

Extension And Testing Of A 2D Hydrodynamic Model For Direct Rainfall Runoff Simulation

While the simulation of flood risks originating from the overtopping of river banks is well covered within continuously evaluated programs to improve flood protection measures, flash flooding is not. Flash floods are triggered by short, local thunderstorm cells with high precipitation intensities. Small catchments have short response times and flow paths and convective thunder cells may result in potential flooding of endangered settlements. Assessing local flooding and pathways of flood requires a detailed hydraulic simulation of the surface runoff. Hydrological models usually do not incorporate surface runoff at this detailedness but rather empirical equations are applied for runoff detention. In return 2D hydrodynamic models usually do not allow distributed rainfall as input nor are any types of soil/surface interaction implemented as in hydrological models. Considering several cases of local flash flooding during the last years the issue emerged for practical reasons but as well as research topics to closing the model gap between distributed rainfall and distributed runoff formation. Therefore, a 2D hydrodynamic model, depth-averaged flow equations using the finite volume discretization, was extended to accept direct rainfall enabling to simulate the associated runoff formation. The model itself is used as numerical engine, rainfall is introduced via the modification of waterlevels at fixed time intervals. The paper not only deals with the general application of the software, but intends to test the numerical stability and reliability of simulation results. The performed tests are made using different artificial as well as measured rainfall series as input. Key parameters of the simulation such as losses, roughness or time intervals for water level manipulations are tested regarding their impact on the stability.
