关于赛鸽的喂养

G·范格雷姆贝根教授认为从饮食角度出发,回归自然的做法比任何方法都重要。只要饲料中含有各类种籽粮,赛鸽就能决定自己的食谱。“满碗”的方法不但最简单易行,而且是最好的方法。     

War3经典回忆之不屈的意志Space的亡灵舞步

相信大家都知道Space这位选手的事迹,这里就不再详细介绍了,现在就带大家进入这场精彩纷呈的比赛吧.比赛地图为扭曲的草场TM,亡灵Space出生在地图的7点钟位置,开局采用的是BZ-BC-BA的狗流开局,一个侍僧在放宪建筑后便踏上了探路之旅.而在地图的5点钟方向,精灵MOON出生于此,采用的开局建筑摆放依旧是传统的月井-祭坛-战争古树,BR这次是放在了533怪点的旁边,并没有大胆的去练实验室.这边Space的探路侍僧在发现了MOON一开始要练533的意图后,便待在了533怪点的附近,等待着MOON开始MF,然后上前去想来一下传说中的神奇一摸!     

Postpartum depression, marital dysfunction, and infant outcome: a longitudinal study

This longitudinal study explores the relationship of postpartum depression (PPD) and marital dysfunction on infant outcomes from birth to 2 1/2 years of age among middle-class, postpartum women. Participants were recruited during the prenatal period. Twelve mothers completed the study throughout a 2 1/2-year period. Questionnaires, semistructured interviews, and observations were used to collect data. Content analysis of the interviews (Morse & Field, 1995) was conducted and thematic patterns were identified. Clinical PPD and marital dysfunction (defined as little or no support or closeness, or verbal, emotional or physical abuse) characterized nearly one in three mothers. Four themes describing the women's postpartum progression were identified: stress, isolation, resentment, and eventual adjustment by creating a new normal. No major developmental delays or behavioral problems were found among the infants. Eight of the 12 mothers who were initially identified as breastfeeding nursed their infants for 6-18 months. Regardless of financial and educational advantages, mothers in the study experienced depression and marital dysfunction. These findings support other studies that confirm the lack of association of PPD with social class or marital status. Childbirth educators and other health care professionals are encouraged to continue providing expectant families with anticipatory education and community resources in order to increase awareness of mental health and marital risks during the postpartum transition.     

Electrical engineering and nontechnical design variables of multiple inductive loop systems for auditoriums

This research analyzed both engineering and nontechnical issues involved in the use of Induction Loop Amplification (ILA) devices in auditoriums or large gathering places for hard-of-hearing individuals. A variety of parameters need to be taken into account to determine an optimal shape/configuration for the ILA device. In many cases, an optimal configuration is different from those proposed for classroom use (Ross, 1969; Hodgson, 1986; Clevenger, 1992). Experimental results were obtained for a double-loop configuration in such a setting (a university gymnasium/auditorium in this case). The results demonstrate that a double-loop configuration is a viable possibility for auditorium use. Several variables using this configuration were examined, and experimentation was done. Various implications, including consequent nontechnical issues specific to this application, are discussed as well. Technical and nontechnical aspects of the ILA configuration need to be examined together when designing an optimal system.

The development of spoken language in deaf children: explaining the unexplained variance

Using a large existing data base on children with severe and profound deafness, 10 children were identified whose level of spoken laguage was most above and 10 whose level was most below that expected on the basis of their hearing loss, age, and intelligence. A study of their personal characteristics, family background, and educational history identified factors associated with unusually high performance; these includes earlier use of binaural ear-level aids, more highly educated mothers, auditory/verbal or auditory/oral instruction, reliance on spoken language as a method of communication, individualized instruction, integration, and structured teaching by parents. Parents of high performers also reported being highly commited to and focusing family resouces on developing their child's spoken language.     

Evaluation and comparison of 50 Hz current threshold of electrocutaneous sensations using different methods

Leakage currents, tiny currents flowing from an everyday-life appliance through the body to the ground, can cause a non-adequate perception （called electrocutaneous sensation, ECS） or even pain and should be avoided. Safety standards for low-frequency range are based on experimental results of current thresholds of electrocutaneous sensations, which however show a wide range between about 50 pA （rms） and 1000 μA （rms）. In order to be able to explain these differences, the perception threshold was measured repeatedly in experiments with test persons under identical experimental setup, but by means of different methods （measuring strategies）, namely： direct adjustment, classical threshold as amperage of 50% perception probability, and confidence rating procedure of signal detection theory. The current is injected using a I cm2 electrode at the highly touch sensitive part of the index fingertip. These investigations show for the first time that the threshold of electrocutaneous sensations is influenced both by adaptation to the non-adequate stimulus and individual, emotional factors. Theretbre, classical methods, on which the majority of the safety investigations are based, cannot be used to determine a leakage current threshold. The confidence rating procedure of the modem signal detection theory yields a value of 179.5 μA （rms） at 50 Hz power supply net frequency as the lower end of the 95% confidence range considering the variance in the investigated group. This value is expected to be free of adaptation influences, and is distinctly lower than the European limits and supports the stricter regulations of Canada and USA.
