The aim of this study was to determine the relationship between inter canine width (ICW) and inter alar width (IAW), inter commissural width (ICoW), and inter canthal distance (ICaD) in Bantu population. Materials and Methods: It was a pilot study included all participants who were aged at least 18 years, without a history of orthodontics treatment from Prosthodontics Department, Faculty of Dental Medicine, University of Kinshasa. The Ethics committee of the National Center of Research for Dental Sciences in DR Congo approved the study protocol (CNRSB 1504.218). The participants medical records were obtained from the interview and dental examination. Nature of the study was explained with participant information sheet, and an informed consent of all participants was obtained. The inclusion criteria were no missing maxillary and mandibular teeth, no diastema, and no anterior restorations, 18 years old before enrollment in the study. The exclusion criteria were inability to meet the above requirements, pregnancy, and refusal to participate in the study. The inter-canine width (ICW), inter alar width (IAW), inter canthal distance (ICaD) and inter-commissural width (ICoW) of each participant were measured with a digital Vernier caliper (Mitutoyo, UK Ltd.,) (0.01 mm) three times and the average value was recorded. The inter canthal distance (ICaD) was measured without applying pressure by bringing the recording parts of the caliper just in contact with the medial angle. The inter alar width (IAW) was marked with a fine marked pencil on the widest outer surface of the alae of the nose on either side or width. Those two points were measured without applying pressure by bringing the recording parts of the caliper just in contact with the outer surface. The participant was told to stop breathing shortly to avoid any change in shape of the nose. The inter-commissural width (ICoW) was determined by measuring the maxillary lip vermilion from commissure to commissure without the

Coffee is a significant industry, accounting for 3% of Vietnam’s GDP, with annual export turnover consistently exceeding USD 3 billion. Despite global economic challenges affecting purchasing power at various times, Vietnam’s coffee exports in December 2023 continued to surge, reaching the highest level in the past 9 months at 190,000 tons, a 59.3% increase compared to November 2023, but still a slight 3.5% decrease from the same period last year. The export turnover reached USD 538 million, a 51% increase from November 2023 and a 26.4% increase from the same period last year. Therefore, forecasting the coffee export volume holds significant importance for coffee producers nationwide. This research employs the Box-Jenkins method to construct an ARIMA model for forecasting Vietnam’s coffee export volume based on annual data published by the General Statistics Office. Results indicate that among the models considered, the ARIMA(1, 1, 2) model is the most suitable. The study also provides short-term forecasts for Vietnam’s coffee export volume. However, the current model is limited to forecasting and is not yet optimized, as the assumed linearity in the model is a simplification.

为研究超声衰减法测量油水环状流截面相含率问题,采用COMSOL仿真软件建立油水环状流模型,选择超声传感器结构尺寸6mm和超声发射频率1MHz进行研究,通过分析油水环状流超声衰减特性,确定油水环状流的超声衰减系数与截面含油率关系,并获得线性关系的测量范围。在此基础上进一步研究非理想环状流相关参数对超声衰减特性的影响,并提出将非理想环状流差别阈限用于定量评价非理想环状流因素对于理想环状流超声衰减法的影响,获得非理想环状流差别阈限±10%以内同心度和椭圆度的变化范围。最后开展了油水环状流静态验证实验。研究结果表明:油水环状流截面相含率在5%~30%范围内,与超声衰减系数呈线性关系,同时在此范围内,非理想环状流差别阈限在±10%以内的同心度和椭圆度变化范围分别为0.75~1和0~5%,实验结果和仿真模拟结果具有近似的上升趋势。

塑料的广泛应用导致大量微塑料进入环境,尤其是水环境,从而产生环境风险。浮游植物等自养生物是湖泊系统的主要初级生产者,是湖泊食物链的关键组成部分,为食物链的上游提供能量和物质基础。同时,浮游植物也是对微塑料响应最敏感的类群。了解湖泊浮游植物等初级生产者对微塑料的响应是探究微塑料对湖泊生态系统功能影响的重要基础。总结了全球湖泊生态系统微塑料的丰度、类型、尺寸、来源等分布特征,系统分析了微塑料暴露对浮游植物等初级生产者细胞结构、基因表达和生长,以及对浮游植物叶绿素a含量、光合活性的影响,并总结了其中的影响机制。总体而言,微塑料会降低初级生产者的叶绿素a含量,剂量越高、尺寸越小,这种抑制作用越强烈;同时,微塑料也会作用于初级生产者,造成细胞膜损伤、DNA损伤,调控其相关功能基因表达,抑制其生长和光合活性等。然而,湖泊生态系统微塑料的实际检出浓度远低于室内暴露实验中的添加剂量,微塑料结构和组分也更为复杂,野外观测结果与室内培养实验之间还不能建立直接的对应关系。因此,未来的相关研究应集中在如何有效联系野外观测结果与室内培养实验结果,进一步聚焦建立可靠的、可应用推广的微塑料浓度与初级生产者之间的剂量-效应关系模型,探究微塑料对湖泊初级生产者的作用机制,为刻画微塑料对湖泊生态系统初级生产者及其功能的作用机制提供科学支撑。

我们将首尔市中心绿意盎然的南山公园对面的商业设施改建成了艺术画廊。利用现有的跃层结构，将多变的展示空间延伸到整个建筑，创造出由白盒子的抽象性和现有建筑的复杂性碰撞而产生的动态艺术空间。现有的外立面被涂成黑色，通过将木材和天空投射到玻璃表面上，消除了建筑本身的存在感，创造出一种引导性的空间体验，将观众的意识从城市的日常切换到白色抽象艺术空间。

20世纪50年代,阿拉伯民族主义浪潮席卷整个中东地区。为维护自身在中东地区的核心利益,美国艾森豪威尔政府的中东政策经历重要转变。执政初期,艾森豪威尔将阿拉伯民族主义划分为“良善”与“激进”两股势力,企图改变阿拉伯民族主义内部的力量对比,削弱“激进”阿拉伯民族主义的政治倾向,然而这种“蓄意引导”的策略并未实现艾森豪威尔政府的预期目标,反而在阿拉伯世界引发大规模的民族主义浪潮。考虑到苏联在中东地区的影响力逐渐加强,美国改变对“激进”民族主义的敌对态度,并试图联合纳赛尔共同对抗活跃于中东地区的共产主义者。主导艾森豪威尔时期美国对阿拉伯民族主义政策的原因与美国对中东战略之根源类似,与意识形态即宗教、共产主义或民族主义价值观无关,其确立与调整的根基在于美国称霸世界的国家利益。

为研究受冻融侵蚀时预应力混凝土构件疲劳特性,开展冻融循环及相同养护时间下常温室内对照试验,根据试验结果和理论计算评估冻融循环引起的预应力损失,该值为冻融室内试件预应力损失(总预应力损失)与常温室内试件预应力损失(收缩、徐变等其他因素引起的预应力损失)之差。研究结果表明,对于相同的混凝土配合比,截面较小且无偏心的试件总预应力损失大于截面较大且偏心的试件;水灰比较高的试件总预应力损失和冻融循环引起的预应力损失均较大;早期阶段冻融循环对试件预应力损失的影响较小;偏心距越大,冻融循环引起的预应力损失越大;混凝土强度越高,冻融循环引起的预应力损失较小,可承受更多次数的冻融循环。

发展壮大新型农村集体经济的过程实质上是组织农民、建设乡村和再造村落共同体的过程。通过利益联结实现社区再造,既是新型集体经济发展助推村落重建的实现图景,也是其目标归属。案例村落在坚持农民主体和村庄本位基础上,在村“两委”带动下,通过精英行动、政府扶持、村企联合和农民参与等方式,发展壮大了新型农村集体经济。以此为基础,村落社区在经济生活、组织构造、社会关系、治理秩序、村落公共性等层面实现了重建。在全面实施乡村振兴战略背景下,应通过政府政策扶持、资源资金注入、产权改革、市场驱动和能人带动等实践路径,以外源驱动激发内生活力,在上下资源联动和内外利益共生中发展壮大新型农村集体经济,使其成为实现农村社区再造的动力源泉。
