1999年世界钛材市场回顾

受亚洲金融危机的影响,世界钛市场需求继１９９８年回落之后,１９９９年又继续下降到了１９９５年钛市场开始好转时的需求水平,具体见表１．这也是世界钛市场有史以来第５次大的波动．１ １９９９年世界钛加工材市场回顾 １９９９年,由于对世界钛需求有主要影响的航空钛市场疲软,世界钛加工材产量比１９９８年下降了１８％,工业用钛材的价格也随之跌到了近几年的低点． 航空钛用量已占到世界钛材需求总量的５０％;高尔夫球棍的钛需求量虽有较大的回落,但仍不失为一主要需求领域．１．１欧美航空钛市场 欧美航空钛市场主要以波音及空…     

1999年世界钛材市场回顾与展望

1　1999年世界钛加工材市场回顾通过1996～1998年世界钛工业间的购并和重组,目前世界钛加工企业间已形成了美、日、俄三足鼎立的局面。世界钛加工企业向集团化、国际化联合的方向更加迈进了一步。1999年,由于主要影响世界钛需求的航空钛市场的疲软,导致1999年世界钛加工材产量比1998年下降了17%。在非航空业领域无大的需求增长前提下,受1998年波音商用客机制造用钛材大量库存的影响,1999年世界钛材产量大幅度下降,而工业用钛材的价格也随之跌到了近几年来的低点。从需求领域来看,航空钛用量占世界钛材需求总量的50%;从单一需求来看,高尔夫球…     

钛锆铪分会2007年年会暨中国钛工业发展论坛

1 关于年会 近年来，中国钛工业发生了深刻的变化：一方面是我国国民经济持续高速发展，特别是目前我国经济发展正处于城市化阶段，国家对有色金属材料的需求强劲，提升了对海绵钛和钛加工材的需求；另一方面是对中国钛工业投资热情高涨，中国钛工业快速发展，2007年中国海绵钛和钛加工材呈翻番式增长已成定局，并已由一个海绵钛和钛加工材的净进口国变成了净出口国，中国钛工业对世界的影响大增。在这样的形势下，研究和判断中国钛工业的走势，分析明了中国钛工业的不足，分析世界钛市场及其走势，为企业找市场，把企业推向国内外两个市场，了解钛的新技术和新的应用领域，就成了本次会议的主题。     

东北钛材加工现状及市场分析

东北是中国的老工业基地，装备能力和技术力量十分雄厚，尤其是钛材的生产和深加工行业对我国的航空、航天和武器装备配套做出过卓越的贡献；钛及钛合金材料的应用市场广阔，近几年辽宁沈阳地区钛及其合金的熔炼、加工材生产发展迅速，年供应市场钛材2000t以上，但是企业规模小、产能低、发展无序，需要进一步进行引导和规范；东北钛材市场潜力巨大，发挥和发掘东北的钛材加工能力及开发东北的钛材市场，具有十分重要的战略意义。     

上萨尔达冶金生产联合公司—俄罗斯钛材加工厂访问印象

以宝鸡有色金属加工厂厂长、西北有色金属研究院院长陈义超教授为团长的四人代表团,于1995年4月下半月应邀访问了世界最大的钛材加工生产企业——俄罗斯上萨尔达冶金生产联合公司。该联合公司位于俄罗斯联邦乌拉尔北部的上萨尔达市。公司创建于1933年,从50年代中期开始生产钛的加工材,现有员工16000人,钛锭最高     

近年世界的钛工业

由于亚洲金融危机的影响，航空市场，特别是亚洲航空市场受到很大冲击，飞机订购取消或推后．几大商用飞机生产商在充分利用库存的基础上，也相应推迟了钛的新订货．世界钛工业在１９９５年开始回复，经过１９９７年的市场需求高峰之后，近两年持续回落，１９９９年的海绵钛和加工材产量已基本降至１９９５年的水平（见图１和图２）． 在钛市场需求的鼎盛时期，各大钛生产商采取扩产、兼并、联合及与钛用户签订长期售货合同等手段，提高产量，扩大市场份额．下面就１９９７年至１９９９年间主要国家钛公司的情况作一简单介绍．１美国１．１…

Benzimidazole resistance in cyathostomes in horses in the Ukraine

The efficacy of treatment with cambendazole was tested in 1-year-old horses on a farm in Dubrovka, Ukraine. Thirty-five horses were treated. Their egg output was compared on the day of treatment and 14 days later with that of 33 untreated horses. Before treatment the mean number of eggs g-1 faeces was 614 in the controls and 766 in horses that had been treated. After 14 days the mean egg output in the controls was 580 and in the treated horses 369. This means a reduction of 54.5%. Only cyathostome larvae could be cultured from faeces collected after treatment. It can be concluded that benzimidazole resistance in cyathostomes is present in the Ukraine.     

Heatstroke in runners in Oklahoma

It is a common opinion that general surgery is the first step for whoever approaches a surgical discipline, and that whoever practices training in general surgery should learn the rudiments of each surgical branch. The role of microsurgery in the training of the general surgeon has not been well-established. Clinical applications of microsurgery in general surgery are few and are rarely required, and have been connected strictly to restricted indications. However, we think that microsurgery could be very useful to the general surgeon because it allows the execution of experimental research on rats, the only possibility permitted by law. In these studies the microsurgeon can perform many times and in a short time the same surgical operation, thus improving his skill, and easily getting familiarity with surgical instruments and sutures.     

Fractures in childhood in Khartoum

A prospective study of fractures in 231 children received at Khartoum North Teaching Hospital(KNTH) was carried out for a period of six months. The incidence of child fracture rated as one per day, then it increased from the age of 5 years onwards in boys and between 6 and 8 years in girls. Most injuries were sustained during the day time, especially between late afternoon and sunset. 82% of injured children presented to a medical facility, while 18% were taken to native healers first. Non-road traffic accidents accounted for 84% of the fractures mainly due to sports, domestic injuries and falls; whereas road traffic accidents were 16% and occurred mainly in pedestrians. Forty three percent of the fractures needed only first aid and splintage while 42% needed closed reduction. Thirty one percent of all patients were treated as inpatients. The long bones were affected in 91% of all fractures, the commonest site being the distal end of the forearm (26%), followed by supracondylar fracture of the humerus (15.6%). In the upper limb, left-sided fractures predominated. The epiphyseal injuries were 3.5% of all fractures, mainly at the distal radial epiphysis. Boys were commonly affected between 13-15 years of age. Open fractures constituted 9.8% of the series and were mainly due to traffic accidents in town dwellers, the most vulnerable bones were those of the leg and foot. Pathological fractures accounted for 2.2% and were due to bone cysts and osteogenesis imperfecta. The problem of child safety and the preventive measures need to be more stressed.     

Apoptosis in experimental myocardial infarction in situ and in the perfused heart in vitro

We report the appearance of apoptotic cells in experimental myocardial infarction (rabbit heart) in in situ and in vitro preparations. Apoptosis was recognized by intravital staining with Hoechst 33342 (Ho342), by nick-end labeling (TUNEL) and by DNA laddering. A steady rise in the relative number of apoptotic cardiomyocytes (apoptotic index) was noted in in situ preparations. Apoptosis was first noted 6 h after the onset of ischemia with its highest value occurring after 72 h. Apoptotic nuclei were absent in remote areas of the left and right ventricles. Apoptotic nuclei within the infarcted area showed diminished intensity of Ho342 fluorescence. Three days after ischemia, a border zone adjacent to the infarcted area consisting of apoptotic macrophages was recognized. A novel finding was the appearance of apoptotic cardiomyocytes in the isolated perfused ischemic heart. Occurring as early as 50 min after the onset of ischemia, a high apoptotic index was present adjacent to the ligature placed around the coronary artery. This observation provides the opportunity to selectively examine factors leading to apoptosis in the ischemic heart under controlled experimental conditions.
