目的：回顾1997／2007伊朗亚兹德地区的200例眼及附属器肿瘤的流行病学特征，确定肿瘤的人群分布及肿瘤位置。方法：回顾观察性病例报道。我们回顾1997／2007医院组织病理学确诊为眼眶肿瘤的病例，分析200例连续病例的年龄分布、病理学、肿瘤来源及肿瘤位置。结果：患者200例（男111例，女89例），其中110例（55．0％）为良性肿瘤，86例（43．0％）为恶性，4例（2．0％）为转移性肿瘤。119例（59．5％）为眼睑肿瘤，21例（10．5％）为眼眶，60例（30．0％）位于眼球。最常见的恶性肿瘤是基底细胞癌（BCC）（25．5％）、鳞状细胞癌（SCC）（6．0％）及黑素瘤（5．5％）。各种类型的痣（15．0％）、皮样囊肿（5．5％）、血管瘤（5．0％）是最常见的良性肿瘤。200例患者按年龄分为两组，18岁以上及18岁以下。18岁以下患者中，最常见的是良性肿瘤（90．1％），恶性肿瘤及转移性肿瘤分别占8．4％和1．5％。然而，18岁以上患者，常见的是恶性肿瘤（51．1％），良性肿瘤占47．1％，转移性肿瘤占1．8％。结论：眼眶肿瘤的病理学特征与患者的年龄及肿瘤在眼及附属器的位置有关。在进行活检及肿瘤切除术之前，患者的发病年龄和肿瘤位置可成为我们制定治疗方案的前提，也是预后评估的重要信息。

Background: Nowadays, though more attention is being paid to oral and dental hygiene all over the world, dental caries and periodontal diseases are increasing daily. We decided to study the effectiveness of natural toothbrush in prevention of dental caries and plaque formation. Methods: This analytic, semi-experimental clinical trial included 390 individuals. Subjects were divided into 3 groups: using natural toothbrush, using artificial toothbrush and using both natural and artificial toothbrush. The plaque index and DMFT was assessed at the beginning of the study until 1 year. ANOVA, Kruskal Wallis, LSD, Paired t-test, chi square, Fisher exact and Mc-Nemar tests were used for data analysis. Results: The plaque index in all three groups showed a mean reduction of 0.71. The mean DMFT in the samples before intervention was 8.38 ± 4.14 and increased to 9.1 ± 4.56. At the end of the study, the lowest plaque index was observed in the group using both the natural and artificial methods. During one year follow-up, the plaque index decreased 1.16, 0.83, and 0.21 degrees in the first, second and third groups. Conclusion: The increase in DMFT in the group that used artificial toothbrush was more than other groups. Thus, use of natural toothbrush leads to a decrease in growth rate of DMFT. Therefore natural toothbrush can be used for the cleaning of teeth and prevention of dental caries.

Next-generation Li-ion batteries are expected to exhibit superior energy and power density, along with extended cycle life. Ni-rich high-capacity layered nickel manganese cobalt oxide electrode materials (NMC) hold promise in achieving these objectives, despite facing challenges such as capacity fade due to various degradation modes. Crack formation within NMC-based cathode secondary particles, leading to parasitic reactions and the formation of inactive crystal structures, is a critical degradation mechanism. Mechanical and chemical degradation further deteriorate capacity and lifetime. To mitigate these issues, an artificial cathode electrolyte interphase can be applied to the active material before battery cycling. While atomic layer deposition (ALD) has been extensively explored for active material coatings, molecular layer deposition (MLD) offers a complementary approach. When combined with ALD, MLD enables the deposition of flexible hybrid coatings that can accommodate electrode material volume changes during battery operation. This study focuses on depositing TiO2$$ {\mathrm{TiO}}_2 $$-titanium terephthalate thin films on a LiNi0.8Mn0.1Co0.1O2$$ {\mathrm{LiNi}}_{0.8}{\mathrm{Mn}}_{0.1}{\mathrm{Co}}_{0.1}{\mathrm{O}}_2 $$ electrode via ALD-MLD. The electrochemical evaluation demonstrates favorable lithium-ion kinetics and reduced electrolyte decomposition. Overall, the films deposited through ALD-MLD exhibit promising features as flexible and protective coatings for high-energy lithium-ion battery electrodes, offering potential contributions to the enhancement of advanced battery technologies and supporting the growth of the EV and stationary battery industries. Ni-rich NMC811 electrodes in lithium-ion batteries face aging challenges with capacity loss and crack formation. To counteract, TiO2$$ {\mathrm{TiO}}_2 $$-titanium terephthalate films, via atomic/molecular layer deposition, enhance structural stability. The flexible organic component improves lithium d

干旱是广泛影响经济和环境的主要自然灾害之一。因此,有必要采用诸如标准化降雨指数(SPI)等指标来研究干旱的影响,以辨析决策和规划的现实条件。本研究的目的是利用SPI指数分析伊朗南部法尔斯省的干旱空间格局。本文根据法尔斯省42个站点的数据,对1990-2019年间的干旱灾害格局进行了评价。评价模型中使用的干旱危害标准包括:该时期的最严重干旱程度、干旱趋势和连续干旱年的最大数量,最终的干旱灾害图是通过计算干旱强度、连续性和趋势三个指标的算术平均值获得的。三个指标的灾害图和最终灾害脆弱图采用反距离加权法(IDW)插值制图,分为无、轻度、中度、重度和极重度5个危害等级。最终的干旱脆弱性图显示,在研究区南部观察到的中度灾害区域占研究区36%,比在北部和中部观察到的严重和非常严重灾害区(占研究区64%)分布范围更小。
