The Zemo Imereti Plateau is located in the easternmost part of the limestone region of western Georgia and is Caucasus’ only karst plateau. It is centrally located in a relatively elevated part of the intermountain plain of the country of Georgia. Lithostratigraphical (petrographic, mineralogical, and XRD) research on terrigenous sediments found in caves in the region was conducted in the Upper Cretaceous limestones located at different hypsometric levels (400 - 700 m). This study focused on allochthonous deposits, which, due to sedimentological features, contains significant and complete information for paleogeographic reconstruction as opposed to the autochthonous sediments. Source provinces of the sediments’ origin were determined using petrographic analysis. Lithological study of the terrigenous sediments indicated their origin from the Racha range, as well as their transportation mechanisms, and sedimentation conditions during deposition. Approximate ages (the end of the Middle Pleistocene and the beginning of the Late Pleistocene) of ancient terrestrial sediments in Rganisklde Cave were achieved by taking into account the geological and geomorphological development of the region. Lithostratigraphical analysis of the cave deposits and modern archaeological data indicate that the formation of the caves in the Zemo Imereti plateau took place mainly during the end of the Middle Pleistocene and in the beginning of the Pleistocene;while on the southern slope of the Racha range and in the surrounding area of Ertso-Tsona (Caucasus southern slope), they formed in the Early Pleistocene.

为探讨东亚地区降水数值模拟中水平分辨率和地形的作用,使用RegCM2区域气候模式,采用不同的模式分辨率和地形,对东亚降水进行对比模拟试验。结果表明,东亚地区降水的模拟效果取决于模式的水平分辨率,模式分辨率越高,模拟的效果越好。使用实际地形的模拟效果好于使用平滑地形的。但同时,使用较高分辨率的平滑地形的模拟,效果好于使用次高分辨率的实际地形的模拟。这表明在东亚地区降水模拟中,分辨率与地形相比,起着至少同样重要的作用。结果指出,对东亚地区降水的模拟而言,使用60 km及以上分辨率可能是必需的。

引用

International Journal of Organic Chemistry 2017年第1期7卷 34-41页

作者： Mamuka Maisuradze giorgi Phalavadishvili Nana Gakhokidze Manana Matnadze Sofo Tskhvitaia Elene Kalandia Department of Chemical and Biological Technology Georgian Technical University Tbilisi Georgia

The aim of the current work is to synthesize the new heterocyclic pentacyclic condensed systems that combine benzothiophen and benzimidazole/triazole into one molecule. The dibenzothiophene was taken as an initial compound and by consistent “extension” was annihilated the imidazole and triazole nucleuses. As a result two new pentacyclic systems were produced: 3H-, 7H-diimidazole[4,5-b][5,4-g] dibenzothiophene-5,5-dioxide and 3H-, 7H-ditriazole[4,5-b][5,4-g] dibenzothiophene-5,5-dioxide with the promising antimi-crobial activity. Their spectral characteristics were studied.

基于中国1∶100万植被图和1∶600万植被区划图,按照通用陆面模式CLM植被功能型分类标准,制作了可用于CLM及RegCM4区域气候模式的25 km×25 km分辨率的中国高精度土地覆盖数据(简称VEG数据).相比CLM默认使用的土地覆盖数据(简称ORG数据),VEG数据不仅能提供更多的土地覆盖局地特征,还纠正了ORG数据中裸地和农作物的比例偏高、灌木的比例偏低等误差.对比使用两套土地覆盖数据的RegCM4多年连续积分结果,分析了不同土地覆盖分布对气温、降水等的影响,并从地表能量收支的角度给出影响机理解释.结果显示:VEG数据的使用,使得模式对冬季气温和降水的模拟能力有一定提高,模式在南部区域偏干偏冷的系统误差有所减弱;采用VEG数据后,由于粗糙度、反照率等下垫面参数的改变及云量的变化,使得地表能量收支发生显著调整.青藏高原地区的气温变化与湍流通量和长波辐射的变化有密切的联系,主要源自粗糙度引起的湍流通量增加、以及云量引起的向下净长波辐射增加.而在中国中部和南部,短波辐射变化更为明显,它与地表反照率的变化相一致.基于所制作的土地覆盖数据,可广泛应用于CLM模式在中国区域的应用之中.

Climate effects of land use change in China as simulated by a regional climate model (RegCM2) are investigated. The model is nested in one-way mode within a global coupled atmosphere-ocean model (CSIRO R21L9 AOGCM). Two multi-year simulations, one with current land use and the other with potential vegetation cover, are conducted. Statistically significant changes of precipitation, surface air temperature, and daily maximum and daily minimum temperature are analyzed based on the difference between the two simulations. The simulated effects of land use change over China include a decrease of mean annual precipitation over Northwest China, a region with a prevalence of arid and semi-arid areas; an increase of mean annual surface air temperature over some areas; and a decrease of temperature along coastal areas. Summer mean daily maximum temperature increases in many locations, while winter mean daily minimum temperature decreases in East China and increases in Northwest China. The upper soil moisture decreases significantly across China. The results indicate that the same land use change may cause different climate effects in different regions depending on the surrounding environment and climate characteristics.

作者： Antonella Benvenuti Mario Miniati Antonio Callari Michela giorgi Mariani Mauro Mauri Liliana Dell’Osso Department of Clinical and Experimental Medicine University of Pisa

AIM: to investigate studies conducted with the Mood Spectrum Structured Interviews and Self-Report versions(SCI-MOODS and MOODS-SR).METHODS: We conducted a review of studies published between 1997 and August 2014. The search was performed using Pubmed and Psyc INFO databases. Analysis of the papers followed the inclusion and exclusion criteria recommended by the PRISMA Guidelines, namely:(1) articles that presented a combination of at least two terms, "SCI-MOODS" [all fields] or "MOODS-SR" [all fields] or "mood spectrum" [all fields];(2) manuscript in English;(3) original articles; and(4) prospective or retrospective original studies(analytical or descriptive), experimental or quasi-experimental studies. Exclusion criteria were:(1) other study designs(case reports, case series, and reviews);(2) non-original studies including editorials, book reviews and letters to the editor; and(3) studies not specifically designed and focused on SCI-MOODS or ***: The search retrieved 43 papers, including 5 reviews of literature or methodological papers, and 1 case report. After analyzing their titles and abstracts, according to the eligibility criteria, 6 were excluded and 37 were chosen and included. The SCI-MOODS and the MOODS-SR have been tested in published studies involving 52 different samples across 4 countries(Italy, United States, Spain and Japan). The proposed mood spectrum approach has demonstrated its usefulness mainly in 3 different areas:(1) Patients with the socalled "pure" unipolar depression that might manifest hypomanic atypical and/or sub-threshold aspects systematically detectable with the mood questionnaire;(2) Spectrum features not detected by other instruments are clinically relevant, because they might manifest in waves during the lifespan, sometimes together, sometimes alone, sometimes reaching the severity for a full-blown disorder, sometimes interfering withother mental disorders or complicating the course of somatic diseases; and(3) Higher

Electroconvulsive therapy in catatonic patients: Efficacy and predictors of response

引用

World Journal of Psychiatry 2015年第2期5卷 182-192页

作者： Federica Luchini Pierpaolo Medda Michela giorgi Mariani Mauro Mauri Cristina Toni Giulio Perugi Department of Experimental and Clinic Medicine Section of Psychiatry University of Pisa Institute of Behavioural Science

Recent evidence favors the view of catatonia as an autonomous syndrome, frequently associated with mood disorders, but also observed in neurological, neurodevelop-mental, physical and toxic conditions. From our systematic literature review, electroconvulsive therapy(ECT) results effective in all forms of catatonia, even after pharmacotherapy with benzodiazepines has failed. Response rate ranges from 80% to 100% and results superior to those of any other therapy in psychiatry. ECT should be considered first-line treatment in patients with malignant catatonia, neuroleptic malignant syndrome, delirious mania or severe catatonic excitement, and in general in all catatonic patients that are refractory or partially responsive to benzodiazepines. Early intervention with ECT is encouraged to avoid undue deterioration of the patient's medical condition. Little is known about the long-term treatment outcomes following administration of ECT for catatonia. The presence of a concomitant chronic neurologic disease or extrapyramidal deficit seems to be related to ECT non-response. On the contrary, the presence of acute, severe and psychotic mood disorder is associated with good response. Severe psychotic features in responders may be related with a prominent GABAergic mediated deficit in orbitofrontal cortex, whereas non-responders may be characterized by a prevalent dopaminergic mediated extrapyramidal deficit. These observations are consistent with the hypothesis that ECT is more effective in "top-down" variant of catatonia, in which the psychomotor syndrome may be sustained by a dysregulation of the orbitofrontal cortex, than in "bottom-up" variant, in which an extrapyramidal dysregulation may be prevalent. Future research should focus on ECT response in different subtype of catatonia and on efficacy of maintenance ECT in long-term prevention of recurrent catatonia. Further research on mechanism of action of ECT in catatonia may also contribute to the development of other brain
