印度尼西亚的对外贸易

国际贸易市场不景气和世界资本主义经济萧条正在对印度尼西亚的对外贸易产生不良影响。这个国家的出口增长率由一九八○至八一年度(财政年度,从四月一日起)的百分之二十四点五下降为一九八一至八二年度的百分之六点六,出口值为二百三十七亿一     

Y-chromosomal STR haplotypes in a population sample from continental Greece, and the islands of Crete and Chios

Eight Y chromosome short tandem repeat (STR) polymorphisms (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) were analyzed in the sample of 117 unrelated Albanian males living in Kosovo. A general STR allelic frequency pattern in the Albanian population from Kosovo corresponds to other European populations. Fourty six haplotypes were observed in single copy. The most frequent haplotypes were (DYS19-DYS385-DYS389I-DYS389II-DYS390-DYS391-DYS392-DYS393) 14-11/11-13-29-24-11-13-13 (10.26%), 14-14/17-12-28-24-10-11-12 (9.40%), 13-16/18-13-30-24-10-11-13 (9.40%), and 14-17/17-13-31-24-10-11-13 (9.40%).     

冷战后的美国对外政策

本文是根据结构现实主义理论大师肯尼斯·沃尔兹今年5月22日在北大的演讲节录而成。演讲中80高龄的沃尔兹从均势理论出发,以一战以来的国际政治结构演变为例,批驳了自由主义、制度主义等对美国外交政策演变的解释力,进而解释了美国冷战后外交政策变化的根本原因在于"一个简单的事件--强权从两个变为一个"。     

析俄罗斯煤炭运输的发展前景

能源供应的可靠性和战略稳定性要求俄罗斯在能源领域必须实现燃料—能源资源的部门结构和分布多元化。煤炭运输未来发展的预测是根据“2 0 2 0年前俄罗斯的能源战略”制定的 ,该战略确定了燃料由目前占绝对优势的碳氢化合物 (石油和天然气 )向煤炭、核能和再生材料过渡的进程。同时 ,能源战略的一些指标应该考虑到经济和能源中长期发展计划的可行性和实现性。建立国家未来的起支撑作用的运输网的首要任务 ,是修筑北西伯利亚铁路线     

Suicide with a butcher's bolt

The captive bolt pistol is an atypical firearm exclusively produced and used for butchery of breeding animals, but in some rare cases, it has been used as a lethal weapon for committing suicide by butchers, breeders and other people who have access to such weapons during their professional activities. This study describes the suicide committed by a butcher in the province of Udine (N. Italy) in 2001 who shot himself with his own captive bolt pistol that produced in the right temporal region a circular wound and a bone lesion of the temporal squama with a groove involving the frontal lobe; he died five days later of the fatal consequences of the meningo-encephalic lesions. The medico-legal issues implicated in this case, seen in the light of the data reported in the international literature, illustrate the difficulties faced when diagnosing these types of lesions, bearing in mind their rarity and peculiar nature, and introduce elements of differential diagnosis regarding lesions produced by similar weapons that lead to ascertainment of the event as accidental, suicidal, or homicidal.     

Organic explosives analysis using on column-ion trap EI/NICI GC-MS with an external source

In this study, a standard method by gas chromatography coupled with mass spectrometry (GC/MS) for the analysis of classical organic explosives was developed. This method was validated in the EI mode, based on the XPT 90-210 standard method. Detection limits (LOD) and quantitation limits (LOQ) were both determined using electronic impact (EI) and negative ion chemical ionization (NICI) modes. These were compared and results showed that in the NICI mode, detection limits were lower than in the EI mode, thus NICI mode appeared to be the best way to analyze nitrate esters. Results of ion trap MS detection were then compared with those obtained in a previous study with single quadrupolar technology. Major ions that were obtained using ion trap MS detection in these two modes were reported.     

Medical malpractice: a study of case histories by the Forensic Medicine Section of Bari

The learning objectives of this paper are to study the actual extent of medical malpractice, the medical acts at risk, and their impact on mortality. The number of suits filed against physicians for deaths resulting from alleged malpractice and autopsies ordered by the Judicial Authority in cases of possible therapeutic misadventures are rising. A major factor pushing this trend is public mistrust of healthcare providers and public and facilities. This mistrust is partly fueled by the mass media which, often to gain larger audience shares, sensationalizes single cases of real or alleged iatrogenic injury. Further, the potential for astronomic settlements, either from the single doctor or from the healthcare institution, has increased the number of legal proceedings that start on the basis of mere suspicion. In this context, the autopsy becomes an important instrument for shedding light on the situation, and it must be carried out by highly qualified and experienced professionals capable of ascertaining the cause of death, identifying any possible misconduct, and assessing its consequences. We reviewed the data regarding autopsies performed at the Forensic Medicine Section of the Department of Internal and Public Medicine of the University of Bari over 1991 to 2000. We culled the cases alleged malpractice and, from these, identified those in which the death had truly been caused by medical error. This study also allowed us to understand the incidence of lethal therapeutic misadventures and to identify the medical and surgical branches more frequently involved.
