头等舱鸡肋化

最近,美航宣布取消其大部分客机上的头等舱座位,其实对大部分航空公司而言,成本基数极高的头等舱均是负累。再考虑到各大航空公司都陆续推出了超级经济舱这一新舱位,其比经济舱座位票价普遍高40%-50%的事实,表明这一舱位的巨大潜力。从财务角度出发,以公务舱、超级经济舱和经济舱这一组合来取代现有的头等舱、公务舱、经济舱组合,是合逻辑的,估计未来岁月得到验证。为头等舱付费的乘客比例很低,自10%到25%不等,这意味着其他的头等舱乘客均通过里程换乘、升级等方式坐在飞机的前舱。另一方面,在收入受限的情况下。

作者： Ahirwar Dheeraj Ahirwar Bharti Kharya MD School of Pharmacy Chouksey Engineering College SLT Institute of Pharmaceutical Sciences Guru Ghasidas Central University Department of Pharmaceutical Sciences Dr. H. S. Gour Central University

Objective To evaluate male antifertility activity of hydroalcoholic extract of Ficus racemosa bark. Methods Swiss male mice were orally administered hydroalcoholic extract of Ficus racemosa bark （50 mg/kg for 30 d and 100 mg/kg body weight for next 30 d）, and the effect of the treatment on body weight, reproductive organs weight, sperm, biochemical profile （sialic acid in epididymis and fructose in seminal vesicle）, fertility and vaginal contraceptive efficacy was investigated. recovery studies were also performed. results Extract reduced fertility to 70% within 60 d. Suppression of cauda epididymis sperm count, motility, viability and abnormal morphology was observed. Marked reduction was noted in the weight of reproductive organs and the level of sialic acid in epididymis and fructose in seminal vesicle. Vaginal application of bark extract exhibited 80% vaginal contraceptive efficacy. After cessation of plant extract treatment, the altered parameters recovered after 60 d. Conclusion Clinical assessment of male antifertility agents should include acceptability, safety and efficacy during and after the treatment. The above results revealed the potential, reversible male antifertility effect of hydroalcoholic extract F. racemosa bark.

阿联酋航空与澳洲航空近日公布了双方长达10年、不涉及持股的联盟方案,引来业界广泛关注。这也同时标志着在与英航联营俗称袋鼠航线的伦敦-悉尼航线后,澳航选择通过猎鹰(迪拜的标志之一)航线重新出发。简单而言,这一合作让澳航的乘客得以利用阿联酋航空在欧洲、中东和非洲的广泛网络;另一方面,阿联酋航空则能通过澳航到达更多澳洲航点,毕竟澳航控制着65%的澳洲内陆航空市场。对澳航而言,其国内航线一直盈利可观。

欧盟的碳排放额度交易计划(EU-ETS)在2012年1月1日起生效,所有直飞在欧盟境内的航班的航空公司,将需要按照其来回欧盟航班的总航程时间向欧盟国家缴交碳税。亚太区航空公司将因此受严重影响,但拥有大量高端客源、机队燃油效率更高的航空公司可能比廉价航空更容易消化新冲击。在目前,要具体分析亚太区哪家航空公司所受冲击最大还有点困难,但在高端客源市场竞争的航空公司更能将增加的成本向乘客转嫁,而执飞欧盟内部短途航线或者机队较旧更耗油的廉价航空,受影响会更大。
