Western Equine Encephalitis

Mosquitoes used for virus analysis in Manitoba are obtained by means of hand catches or by the use of light traps, sometimes supplemented with dry ice. A trap is described that has been used successfully for this purpose during the past three years. This trap is simple to operate, the insects are taken in good condition for identification, and newly emerged specimens are killed, thereby eliminating the majority of those that could not possibly be infected with the virus of western equine encephalitis. The methods of shipping, sorting, identifying, and storing specimens are given. These methods are, in large part, standard entomological procedures adapted to present needs.

Three Rivers

Six major rivers flow through the Kruger National Park (KNP). All these rivers originate outside and to the west of the KNP and are highly utilized. They are crucially important for the conservation of the unique natural environments of the KNP. The human population growth in the Lowveld during the past two decades brought with it the rapid expansion of irrigation farming, exotic afforestation and land grazed by domestic stock, as well as the establishment of large towns, mines, dams and industries. Along with these developments came overgrazing, erosion, over-utilization and pollution of rivers, as well as clearing of indigenous forests from large areas outside the borders of the KNP. Over-utilization of the rivers which ultimately flow through the KNP poses one of the most serious challenges to the KNP's management. This paper gives the background to the development in the catchments and highlights the problems which these have caused for the KNP. Management actions which have been taken as well as their results are discussed and solutions to certain problems proposed. Three rivers, namely the Letaba, Olifants and Sabie are respectively described as examples of an over-utilized river, a polluted river and a river which is still in a fairly good condition.

Frequent Reference

One of the difficulties which hinder the extended use of the nut-oil-cakes (palm kernel, coconut and ground-nut) is the prevalent impression that these cakes deteriorate rapidly on keeping. In recent articles dealing with these cakes frequent reference has been made to this point. Thus Voelcker (9) in his Annual Report for 1914 states that “one inconvenience attaching to palm-nut and coconut cakes is that they do not keep as well as linseed and cotton cakes and that there is a tendency for them to turn rancid.” In his Report for 1915, however, he says, “I have come across but few instances either with palm-nut cake or meal, in which these have been rancid or not in good condition.” Murray (8) states that manufacturers should realise that they still have to reassure farmers regarding the keeping qualities of palm kernel cake. In a later article in the Journal of the Board of Agriculture (3) it is stated that “palm-nut kernel cakes in the past have had the reputation of soon going rancid…. At the present day, before the kernels are crushed they are subjected to a process of cooking, by which the ferment that causes the oil to turn rancid is rendered inactive.” The validity of this latter assertion seems doubtful in the light of the recent work of Calder (2) which shows that the lipase, present in the resting seed in the form of its zymogen, is not destroyed during the manufacture of the cake, the mass of crushed kernels not being sufficiently heated in every part prior to pressing to secure this object completely. Similar statements have been made as to the liability of coconut and ground-nut cakes to become rancid on storing (3,4).

BackgroundThe caddisfly genusOecetiscurrently contains 534 valid species. Its larval stages are found in freshwaters around the world. The adults can be distinguished from other Leptoceridae by the unbranched forewing M vein and the exceptionally long maxillary palps. In the Neotropical region, 55 species ofOecetishave been recorded and most of them can be placed in one of the six species groups known from this biogeographical region: theavara-,falicia-,inconspicua-,punctata-,punctipennis-, andtestacea-groups. More than 50% of the known diversity of NeotropicalOecetishas been described in the past 40 years. Here, we describe an additional 14 new species ofOecetisto further document the diversity of this genus in the Neotropical region.MethodsThe descriptions and illustrations presented here are based on male specimens. Specimens were collected with Malaise traps or ultraviolet light traps. They were preserved in alcohol or pinned as stated in material examined section. Specimens had their genitalia prepared in 85% lactic acid to better observe internal characters and illustrations were aided by the use of a microscope with drawing tube attached.Results and DiscussionThis study raises the number of species ofOecetisin the Neotropics from 55 to 69. Eight of the new species presented here could not be reliably placed in one of the known species groups (Oecetis acuticlaspern. sp.,Oecetis flintin. sp.,Oecetis carinatan. sp.,Oecetis cassicoleatan. sp.,Oecetis blahnikin. sp.,Oecetis gibbosan. sp.,Oecetis licinan. sp., andOecetis pertican. sp.). The others are placed in thepunctata-group (Oecetis bidigitatan. sp.,Oecetis quasipunctatan. sp.),testacea-group (Oecetis plenuspinosan. sp.), andfalicia-group (Oecetis calorin. sp.,Oecetis hastapullan. sp.,Oecetis machaeran. sp.). Most of the diagnostic characters rely on structures of the inferior appendages and phallic apparatus, and the shape of tergum X.

Selective Nonoperative Management

Background. Selective nonoperative management has become the standard for liver injuries. Accordingly, we cannot perform surgery for liver injuries as frequently as in the past. This report is aimed at sharing a valuable experience of postoperative complications after surgery for a liver injury. Case Presentation. A 40-year-old man was stabbed in his abdomen and underwent an emergency laparotomy for a severe liver injury. Five months after the operation, he developed fever, and purulent discharge was observed from an abdominal fistula. He was diagnosed with a perihepatic abscess and duodenal perforation due to the pledgets used for the operation. He underwent a second surgery to remove the pledgets and the abscess cavity for infection control and was discharged in good condition. Conclusion. The intra-abdominal environment should be considered contaminated due to bile leakage in surgeries following liver injury. Furthermore, nonabsorbable agents should not be used in these contaminated areas.

Technological Developments

To minimize travel to light traps sited at a considerable distance from headquarters, the authors have developed a battery of seven light traps, to keep nightly catohes separate and in good condition for a period of up to one week.The 100-watt clear, incandescent attractant lights are switched on in succession by a programmed multiple switch based on a seven-day, clock-driven thermograph drum. Seven cams are fitted at intervals equivalent to 24 hours on the drum surface, each of arc length to keep one of the seven roller lever actuator switches closed for the night hours of orie dav per week.

During the past decade, criterion system of impairment of Assets has experienced a process from scratch and scattered to highly-developed in China. So far, “Accounting Standards for Enterprises No. eighth -- Asset Impairment ” has been implemented for nearly five years, and listed companies had compiled interim and annual reports during the 2007-2011 period which experienced a good condition overall. It is a significant breakthrough in the processing of accounting standards and accounting system, which constructs and consummates the system of asset impairment standard, require enterprises to reflect the value of the asset fairly and prevent inflated profits from property price foam. Introduction In recent years, the International and the domestic practice indicates that, in order to reflect the true value of the assets reliably, so as to improve the quality of accounting information, and reduce the uncertainty in decision-making, relevant accounting standards for recognition, measurement and presentation about asset impairment must be developed and implemented. During the past decade, criterion system of impairment of Assets experiences a process from scratch and scattered to highly-developed. In February 15, 2006, Ministry of Finance of the People’s Republic of China issued the "Accounting Standards for Enterprises No. eighth -- Asset Impairment" (Ministry of finance, PRC, 2006a), which regarding as the complete establishment of Chinese asset impairment standard system. Based on the experience of formulation and implement the accounting system and accounting standards, the Ministry of Finance drew some lessons from international accounting standards, and adopted the mode of “basic standard of impairment of Asset commanding other relative individual specific standards” to build asset impairment standard system, which has strong international significance.

AbstractSeasonal emergence, abundance, biting and oviposition activity of Mansonia perturbans (Walker) were monitored in southwestern Ontario during 1977 and 1978. Adults emerged from 13 June until 24 August with the greatest emergence occurring in mid-June and mid-July. In both 1977 and 1978, adults were collected by dry ice-baited CDC light traps from 7 June until at least 7 September, with a peak of abundance in late June, followed by a smaller second peak in early August. Biting activity occurred from the second week of June until the first week in September with a maximum during the last week of June. Oviposition occurred from 30 June until 24 August with a maximum in early July.
