Healthcare decisions are based on scientific evidence obtained from medical studies by gathering data and analyzing it to obtain the best results. When analyzing data, biostatistics is a powerful tool, but healthcare professionals lack knowledge in this field. This lack of knowledge can manifest itself in situations such as choosing the wrong statistical test for the right situation or applying a statistical test without checking its assumptions, leading to inaccurate results and misleading conclusions. With the help of this “narrative review”, the aim is to bring biostatistics closer to healthcare professionals by answering certain questions: how to describe the distribution of data? how to assess the normality of data? how to transform data? and how to choose between nonparametric and parametric tests? Through this work, our hope is that the reader will be able to choose the right test for the right situation, in order to obtain the most accurate results.

A top-down silicon nanowire fabrication using a combination of optical lithography and orientation dependent etching has been developed using Silicon-on Insulator（SOI） as the starting substrate. The design of experiments for the optimization of the process flow especially on the orientation dependent etching using potassium hydroxide（KOH） and Tetra-Methyl Ammonium Hydroxide（TMAH） are presented in this paper. Based on the etching experiments using silicon substrates, KOH with added isopropyl alcohol（IPA） had shown to have a consistent etch rate with acceptable silicon surface roughness as compared with its other counterparts. The concern regarding the effect of line edge roughness（LER） as a result of optical lithography was highlighted and, therefore, the optimization of the patterning procedure was also discussed and presented.

Naturally occurring tubular halloysite is a potential drug carrier because of the significant deposit, unique mesoscopic (2-50 nm) or even macroscopic (>50 nm) lumen, and excellent biocompatibility. The drugs loaded on halloysite exhibited slow release under the diffusion limitation by the halloysite nanotube. However, due to the weak interaction between halloysite and guest, the loading capacity of halloysite was relatively low. This drawback severely limits the application of halloysite as carrier in pharmaceutics. In this study, the performance of halloysite as carrier for ibuprofen (IBU) loading was investigated for the first time. The effects of 3-aminopropyltriethoxysilane (APTES) modification and thermal treatment of halloysite on the loading and release of IBU were also studied. The purified halloysites were heated at 120 ℃ and 400 ℃ (labeled as Hal/120 and Hal/400), and then modified with APTES (labeled as Hal/120-A and Hal/400-A). The loading of IBU was achieved by soaking method (labeled as IBU-Hal/120, IBU-Hal/400, IBU-Hal/120-A, and IBU-Hal/400-A.). The in vitro drug delivery assays were performed in phosphate buffer solution. IBU was loaded mainly into the lumen and partially on the external surface of halloysite. The order of IBU contents was as follows: IBU-Hal/400-A (14.8wt%) > IBU-Hal/120-A (12.7wt%) > IBU-Hal/400 (11.8wt%) > IBU-Hal/120 (11.7wt%). The IBU was initially anchored to the surface hydroxyl groups of halloysite by hydrogen bonding, followed by further bonding of IBU with the anchored IBU to form hydrogen-bonded aggregates. The APTES modification of halloysite promoted the loading of IBU by introducing a strong affinity through electrostatic attraction between the introduced aminopropyl groups of APTES and the carboxyl groups of IBU. Thermal treatment at 400°C did not destroy the tubular morphology or the crystal structure of halloysite and had little effect on IBU loading in unmodified halloysite. However, thermal treatment by reducing

The Effect of Temperature on Transformation of Kaolinite to Halloysite-like Nanoroll Via One-step Delamination

＜正＞There are very few investigations on best spectrum for mesopic visibility and even less data on the spectrum of discomfort *** have studied these two perceptions and came to the conclusion,that it is not enough to optimise for the combined photopic and scotopic luminosity functions but the chromatic components have to be taken into consideration too. In this paper investigations to determine optimum SPD for mesopic conditions providing good visibility and low glare will be described.

Tubular halloysite is a hydrated polymorph of kaolinite, commonly considered as its associated mineral. Due to its unique mesoscopic (2–50 nm) tubular structure, it has attracted great interest in the field of adsorption, catalysis, and nanocarrier. The halloysites in different deposits present various morphological properties which significantly affect the interface reactions with functional guests. These scattered properties in addition to their low purity severely limit the actual applications of halloysite in industry.

清选系统是气吸式红枣收获机的重要组成部分,降低清选含杂率、损失率和破损率是实现红枣收获机械化的关键技术。利用枣、杂惯性和流体力学特性差异,设计了一种惯性气流式红枣清选系统,并对其关键部件及结构参数进行设计和分析。采用Fluent软件探明了该清选系统内气流运动形成的“∞”形旋流有利于枣、杂的清选。为获得清选系统最佳工作参数,以气流速度、调节板开度为试验因素,以含杂率、损失率和破损率为评价指标,设计二次正交旋转组合试验。建立试验因素与指标间的回归模型,采用多目标优化算法进行参数优化,确定清选系统最优参数组合:气流速度为32.0 m/s,调节板开度为3.4 cm。在该条件下开展验证试验,得到含杂率、损失率和破损率分别为1.38%、3.37%和0.60%,与优化参数相比分别增加了0.06、0.12、0.03个百分点。该清选系统满足枣、杂清选作业要求。
