小财主养成记

许多成年人至今还和存钱奋斗着,但是大部分的人最终都成为了"月光族"。大人亦是如此,所以教导孩子存钱就成了一场旷日持久的"攻坚战",现在的小孩子不仅没有储蓄的习惯,用钱的时候更是大手大脚,想买什么东西就向父母要钱,他们的字典里没有"节俭"这个词。很多父母也认为孩子们要什么就给什么是爱他最好的体现。但是即使给孩子金山银山,也不如给他创造财富与打理财富的头脑和双手。因为坏的理财观念一旦形成,就很难改变。因此,一个人的理财教育,应该从孩童时代便开始做起。为人父母,如何树立正确的理财观念,以身作则为孩子做个好榜样?如何使用正确的方法向孩子灌输正确的价值观呢?如何通过对孩子理财教育将学习与情绪相结合,了解子女各方面的情绪问题,从而帮助孩子了解及认识自己,把个人潜能全面发挥出来?你的小财主,由你做主。     

Repair of shoulder luxation in a horse

Shoulder luxation in a 3-year-old Thoroughbred filly was treated by closed reduction, using a calf jack to provide traction on the limb. Arthroscopic examination of the shoulder allowed removal of soft tissue and bony debris. After surgery, the filly was confined to a box stall for 6 months. Eight months after surgery, the filly was doing light work and was not lame. Muscular atrophy present before surgery had resolved. Use of a calf jack may allow reduction of shoulder luxation under field conditions.     

Surgical treatment of a mural teat abscess in a cow

A 6-year-old multiparous Holstein cow was admitted for evaluation of progressive milk flow obstruction of one quarter of the udder. Physical examination findings suggested the presence of a mural teat abscess. Ultrasonography substantiated the physical examination findings and delineated the extent of the lesion. Surgical excision of the abscess en bloc yielded satisfactory functional and cosmetic results.     

Ileocecal intussusception in horses: 26 cases (1981-1988)

The case records of 26 horses with ileocecal intussusception over a 7-year period were reviewed to determine clinical features of the disease and response to treatment. The median age of horses with ileocecal intussusception was 1 year and ranged from 2 weeks to 19 years. There was no apparent gender or breed predisposition to this disease. An acute form of ileocecal intussusception was diagnosed in 19 horses with signs of moderate to severe abdominal pain of less than or equal to 24 hours' duration, and a chronic form was diagnosed in 7 horses with signs of intermittent, mild to moderate abdominal pain of more than 3 days' duration. Horses with chronic ileocecal intussusception had a history of weight loss or failure to gain weight, slow growth, poor appetite, low-grade pyrexia, and postprandial signs of abdominal pain. At surgery, the involved segments of intestine (intussusceptum and intussuscipiens) in chronic cases were 2 to 10 cm long, and the ileum and much of the distal portion of the jejunum were flaccid, dilated, and thick walled. In the acute cases, the length of involved intestine ranged from 6 to 457 cm. Whereas only 1 of 7 chronic intussusceptions (14%) could be reduced, 9 of 19 (47%) acute intussusceptions were reducible. Surgical treatment included resection and jejunocecostomy (6 horses), partial resection through a cecotomy and a side-to-side jejunocecostomy (2 horses), and a side-to-side ileocecostomy or jejunocecostomy without resection (12 horses, 7 of which had chronic intussusception). Six horses with acute intussusception were euthanatized before or during surgery.(ABSTRACT TRUNCATED AT 250 WORDS)     

Nucleotide sequence of a lysine transfer ribonucleic Acid from bakers' yeast

The nucleotide sequence of one of the two major lysine transfer RNA's from bakers' yeast has been determined. Its structure is compared to that of a lysine tRNA from a haploid yeast. A total of 21 nucleotides differ in the two molecules. Only the T-psi-C-G (thymidine-pseudouridine-cytidine-guanosine) loop and its supporting stem are identical.     

Polywater: an attempt at synthesis in a gas discharge

An attempt to produce polywater in a corona discharge in moist air was unsuccessful. However, the major product produced, nitric acid, has a midrange infrared spectrum which is strikingly similar to that reported for polywater. The Raman spectrum offers a better means of distinguishing between nitric acid and polywater than the infrared spectrum does.     

Mapping neuronal inputs to REM sleep induction sites with carbachol-fluorescent microspheres

The cholinergic agonist carbachol was conjugated to latex microspheres that were fluorescently labeled with rhodamine and used as neuroanatomical probes that show little diffusion from their injection site and retrogradely label neurons projecting to the injection site. Microinjection of this pharmacologically active probe into the gigantocellular field of the cat pontine brain stem caused the awake cats to fall into rapid movement (REM) sleep indistinguishable from that produced by free carbachol. Three-dimensional computer reconstruction of the retrogradely labeled neurons revealed a widely distributed neuronal network in the pontine tegmentum. These pharmacologically active microspheres permit a new precision in the characterization and mapping of neurons associated with the control of behavioral state and of other cholinergic networks.     

Simultaneous analysis of grain and grain-based products for ethylene dibromide, carbon tetrachloride, and ethylene dichloride

A method is described for the simultaneous measurement of parts per billion levels of the fumigants ethylene dibromide, carbon tetrachloride, and ethylene dichloride in grain and grain-based products. The fumigants are isolated by hexane co-distillation, separated by capillary gas chromatography, and detected with a mass spectrometer in the selected ion monitoring mode. Recoveries are greater than 90% and standard deviations are approximately 10% of the quantity measured. The method is free of interferences and its precision and accuracy are enhanced by the use of tetradeuterated ethylene dibromide and ethylene dichloride as internal standards.
