Land.lid.s pose a threat to property both in the populated.and.cultivated.areas of the Gerecse Hills (Hungary). The currently available land.lid. inventory d.tabase hold. the record. from many sites in the area, but the d.tabase is out-of-d.te. Here we ad.ress the problem of revising the National Land.lid.s Cad.stre land.lid. inventory d.tabase by creating a land.lid. suscept-ibility map with a multivariate mod.l based.on likelihood.ratio functions. The mod.l is applied.to the Tand.M-X d.M (0.4″ res.), the current land.lid. inventory of the area, and.d.ta acquired.from geological maps. By comparing the d.stributions of four variables in the land.lid. and.non-land.lid. area with grid.computation method., the mod.l yield. land.lid. susceptibility estimates for the stud. area. The estimations show to what extent a certain area is similar to the sample areas, therefore, its likelihood.to be affected.by land.lid.s in the future. The accuracy of the mod.l pred.ctions was checked.in the field.and.compared.to the results of our previous stud. using the SRTM-1 d.M for a similar analysis. The mod.l gave accurate estimates when certain correction measures were applied.to the input d.tasets. The limitations of the mod.l, the input d.tasets, and.the suggested.correction measures are also d.scussed.

Controlling the morphology of semicond.ctor nanocrystals has typically relied.on controlling the concentration and.species of surface ligand. utilized.in synthesis. Specific shapes, such as branched.structures are of particular interest as the light harvesting and.charge separating layer in a photovoltaic d.vice. In this work we quantify how changes in the reaction temperature affect the resulting morphology of the nanocrystals. The narrowness of the temperature range over which the morphological transition occurred.provid.s guid.nce to the tolerances necessary in the synthesis of Cd.e utilized.in commercial d.vices on a large scale.

背景与目的脂肪移植是一项很有前景的软组织填充增大技术，但移植疗效持久性存在高度不可预知性，而且影响移植成活率的因素尚未明确。因为具有分化的潜能和释放生长因子的能力，脂肪来源干细胞（ad.pose-d.rived.temcells，Ad.Cs）可在移植修复过程中起关键作用。我们旨在确定Ad.Cs在人体脂肪中呈现的生物学特性是否与移植体积的体内效果保持存在关联。方法利用标准的离心分离技术对从8例人体受术者获取的脂肪抽吸物进行处理，然后将其注射至6周龄无胸腺裸鼠躯体两侧。测量移植物的质量和体积，于移植后8周进行包含针对血管的Cd.1^＋染色的组织学评估。从各供体脂肪抽吸物中分离获取基质血管细胞群（stromalvascularfraction，SVF），利用多参数流式细胞术对其表面标记物进行分析，并对其增值、分化能力和正常含氧量／低含氧量血管内皮细胞生长因子（vas—cularend.thelialgrcwlhfactor，VEGF）的分泌情况进行实验研究。结果从不同供体中获取的SVF，其Cd.4^＋祖细胞含量百分率存在较大差异，其平均值为21．3％±15．O％（X±s）。SVF细胞的增殖速率和成脂潜能在不同供体间存在较为中等差异。在小鼠异种移植研究中，移植后8周体积保存的量约为36％～68％，总体平均值为52％±11％。SVF中Cd.4^＋祖细胞的含量与脂肪移植效果持久性方面存在较强的关联（P〈0．05）。结论在不同患者之间，其脂肪组织的内在生物学特性存在差异。特别是SVF中Cd.4^＋祖细胞的浓度可能是影响脂肪移植持久性的因素之一。

Ammoniated.bagasse is a plant-d.rived.organic sorbent that can be used.for capturing oil and.for supplying slow-release nutrients to oil-d.grad.ng microorganisms. We investigated.the oil-wicking behavior of this sorbent und.r various cond.tions for its effectiveness in remed.ating oil-contaminated.wetland.. Abiotic microcosms simulating a wetland.environment were used.to assess the influence of sand.particle sizes （20x30 and.60x80 U.S. mesh）, d.grees of oil saturation （25% and.75%）, water table levels （on top of the clean sand.layer, oiled.sand.layer, and.sorbent layer）, and.the presence of sorbent. Results ind.cated.that oil wicking favors higher oil contamination, larger sand.particle size, and.low water coverage. Water coverage was the pred.minant factor limiting the effectiveness of sorbent. The most plausible explanation for this limitation was that sorbent captured.more water than oil at higher water coverage.

Over the last 20 years, laparoscopic colorectal surgery has shown equal efficacy for benign and.malignant colorectal d.seases when compared.to open surgery. However, a laparoscopic approach red.ces postoperative morbid.ty and.shortens hospital stay. In the quest to optimize outcomes after laparoscopic colorectal surgery, red.ction of access trauma could.be a way to improve recovery. To d.te, one method.to red.ce access trauma is natural orifice specimen extraction(NOSE). NOSE aims to red.ce access trauma in laparoscopic colorectal surgery. The specimen is d.livered.via a natural orifice and.the anastomosis is created.intracorporeally. d.fferent method. are used.to extract the specimen and.to create a bowel anastomosis. Currently, specimens are d.livered.transcolonically, transrectally, transanally, or transvaginally. Each of these NOSEproced.res raises specific issues with regard.to operative technique and.application. The presumed.benefits of NOSE-proced.res are less pain, lower analgesia requirements, faster recovery, shorter hospital stay, better cosmetic results, and.lower incisional hernia rates. Avoid.nce of extraction site laparotomy is the most important characteristic of NOSE. Concerns associated.with the NOSE-technique includ. bacterial contamination of the peritoneal cavity, inflammatory response, and.postoperative outcomes, includ.ng postoperative pain and.the functional and.oncologic outcomes. These issues need.to be stud.ed.in prospective rand.mized.controlled.trials. The aim of this systematic review is to d.scribe the role of NOSE in minimally invasive colorectal surgery.

Many variations can be applied.to trad.tional mammoplasty techniques to improve outcomes in certain situations. The purpose of this report was to d.monstrate the ind.cations and.benefits of mammoplasty autoaugmentation using an extend.d.superomed.al ped.cle. All patients who und.rwent transfer of an extend.d.superoped.cleto other parts of the breast for autoaugmentation were includ.d. Ind.cations were d.termined.and.outcomes were assessed. Forty-eight patients were includ.d.in the series. The average follow-up was 2.1 years. Ind.cations were categorized.into reconstruction of a partial mastectomy d.fect (oncoplastic group, n = 18), upper pole volume in the contralateral mastopexy (implant reconstruction group, n = 9), and.volume improvement and.suspension (massive weight loss group, n = 21). The overall complication rate was 15% (n = 7/48), with a revision rate of 10% (5/48). The extend.d.superomed.al ped.cle is a reliable and.versatile ad.unct to regular mastopexy techniques for various ind.cations. It gives us the ability to transfer vascularized.tissue from the lower pole to areas that require autoaugmentation.
