 A fastener facilitates assembly as well functionality, making it is a significant part of any design. In fact, it can make or break the machine or ed hardy product. Fasteners selected should not be an afterthought — an after-the-fact fix can be complicated and impracticably expensive. Therefore, we offer the following guidelines to help you in the selection of fasteners. Grade 8 Socket Head Cap Screws (SHCS) are the screws of choice, in my opinion. The head design of the SHCS allows the use of ball-nose hex key tooling. This is a much more forgiving system with regards to the tool angle and titanium fasteners thrust pressure that must be applied by the assembler. Avoid using screwdriver-driven or hex-head bolts. Screwdriver slots are too easily stripped. It is best to apply the wrench to the nut side only, not to both the nut and bolt sides at once.Try to use only the fit 2A for external threads or fit 2B for internal threads. Fit 2A and 2B is the middle of the tolerance range for screw systems. Fit 1A and 1B are for loose, open tolerances whereas fit 3A and 3B are for tight tolerance systems. When your design allows, use only coarse thread fasteners. Designing with only coarse threads reduces bolt inventories. Fine threads require very clean assembly conditions for reliable wow gold torque readings. The practical use of fine threads is in adjustment mechanisms. Also, since a fine thread is slightly stronger, it could be used where size or weight limitations will not allow the next size of coarse thread. These are marginal uses for the added cost of also stocking fine sizes.

Stainless steel bolts and nuts are preferred whenever possible. Cadmium and zinc plating is toxic in manned environments. The extra cost of stainless steel fasteners is largely offset by the cost of plating and the environmental restrictions on the plating vendors. Decide
car wash on which system to use, inch or metric, and only use that system. This reduces the inventory of stocking a complete set of both systems.If locking fasteners are required, use a chemical locking method such as a liquid loctite thread sealer and locking fluid in lieu of a mechanical locking device. Bolts that rely on deformed metal threads are chip producers and can only be used once. They are also difficult to torque to precise low torque values. Bolts with nylon locking inserts can only be used once and are temperature sensitive. Avoid lock washers of any kind since they are also chip generators.Avoid self-tapping screws. These are also chip generators and remove some of the thread material each ed hardy clothing time they are used. Chip generation is death to an electronic assembly and even a pure mechanical system may be installed near an electronic system.Use a commercial threaded stainless steel insert in all aluminum assemblies, no exceptions. An aluminum thread galls too easily to risk use. If a part is too thin to use an insert, then use a nut.Never use a jam nut, only use full height nuts. One cannot be sure that the jam nut was not over-tightened by someone in the past. Why take the chance on a fastener that is really an undersized, half-sized component.Use half-dog internal hex-socket set screws. Cup-point set screws will mark the mating shaft but have very high holding. A prehardened shaft will be marked less with half-dog set screws.

 在秋日里怀孕的妈妈,无疑是最幸福的。秋高气爽,不仅夜间睡眠充足保证了生理代谢旺盛,而且秋季蔬菜、瓜果丰富,所以营养和维生素完全跟得上哦。不过,秋季天气的网站建设 不断变化,一不留神,就会引起感冒、免疫力下降等各类疾病。究竟怎样才能做一个秋天里最健康漂亮的准妈妈?昨日,记者采访了锦江区妇幼保健院、成都维多利亚女子医院、市二医院等相关妇科专家,请她们从如何预防秋季孕妇常见病症、打理营养膳食、正确穿衣以及心态的调节上给广大准妈妈们教上一课。对身怀六甲的准妈妈来说,秋天是比较舒服的季节。不过,要想做个健康的秋孕准妈妈,据成都维多利亚女子医院李桂兰主任医师介绍,一定得做好“三防”———防腹泻、防便秘、防呼吸道疾病。  预防腹泻是因为秋天上市孕妇饮食 的新鲜瓜果较多,但如果不注意食品卫生,抵抗力相对较差的孕妇就容易闹肚子了。闹肚子很可能刺激孕妇宫缩甚至导致早产。因此,孕妇秋天一定要注意饮食卫生,吃新鲜瓜果一定要洗净。  其次,孕妇第二个要注意的是便秘。秋天气候干燥,孕妇如不注意饮食调理,就可能便秘。建议孕妇饮食中油腻食物和肉类要适量,别一味追求贴秋膘,要适当增加新鲜水果和蔬菜的比例。另外,多喝水、养成定时排便习惯。  最后,秋天天气转凉,孕妇更容易感冒、患上呼吸道疾病。锦江区妇幼保健院产科专家邵萍主任告诉记者,感冒是秋天孕妇最容易患的病之一。一般来讲,孕妇用药应当谨慎,原则上是能不用就不用,千万不要滥用抗生素,即便服用中药,最好也要接受医生指导,不要自己买药服用。因为大多数药物可从母体经胎盘进入胎儿体内,其中一部分特价机票可对胎儿造成损害,有致畸作用。此外需要特别注意的是,妊娠早期感冒发烧可影响胎儿中枢神经系统发育,甚至导致胎儿畸形。  据邵萍称,感冒重在预防,孕妇要加强营养、适度活动,保持良好心情,以增强机体免疫力。室内要经常通风换气,经常用醋熏蒸房间;孕妇最好不要长时间待在人多的场合,以免交叉感染。  此外,孕妇还要特别当心风疹、巨细胞病毒的感染,这类病毒可能导致胎儿畸形。尤其在怀孕早期,如怀疑有感染,最好去医院做相关检查。

年龄是最大的因素,24岁以下怀孕的孕妇基本认为得糖尿病的机会很少或者是没有,而且在国外24岁以下的孕妇不做糖尿病筛查。如果超过30岁就是糖尿病的高危人群,30岁以上
hunterlab 的人都要注意预防糖尿病的发生。还有家族史的因素。最重要的高危因素就是体重,孕前超重和肥胖的孕妇得糖尿病的机会就会大。怀孕早期体重增加过快也是得糖尿病的基础。能控制什么呢?控制怀孕期间的体重。从饮食上控制,体重就是从吃的食物当中来的,你可以运动消耗一部分,剩下大部分是供身体消耗的。高危人群体重跟正常人群是一样的,肥胖就控制长的慢一些。从饮食硬盘修复上安排,首先生活规律要好,一定保证一天三餐,建议在早晨8点钟之前一应要进食早餐,血糖高还是低是由身体里面的胰岛素激素来调控的,如果不在合适的时间给它一个适当的刺激,它就会逐渐弱下来。所以一定要在正常的时间进餐,早餐孕妇一定要包括主食。一天三餐安排合理,一定要保证充足的睡眠。8—10个小时是孕妇比较理想的睡眠时间,中午睡上半个小时到一个小时,晚上补够其它睡眠。  还有一个是运动,糖尿病认为胰岛素抵抗造成的,运动是对缓解胰岛素抵抗是有帮助的。运动之后胰岛素的敏感性增加。

The New Jackie large shoulder bag is doubtlessly the IT BAG of Gucci design house. By far, the house has released countless versions of this bag for Panerai seasons. As far as all the information I have got, this Purple and Violet New Jackie Large Shoulder Bag is the most expensive one among them, which is also the most dazzling piece of the Fall Winter 2009 collection. As you may have noticed it, the average price of New Jackie bag is about 2,000 dollars, but this bag is as pricy as 4640 dollars — also the same price for Gucci Diaper Bags.
