The “middle income trap” is a significant theoretical and practical issue closely related to the economic and social transition and sustainable development of a country. This paper explores the essence of the “middle income trap” and ways to avoid it. It reveals that the inner nature of the “middle income trap” lies in the institutional transition dilemma, which results essentially from a lack ...
African pit latrines produce prodigious numbers of the latrine fly, Chrysomya putoria, a putative vector of diarrhoeal pathogens. We set out to develop a simple, low-cost odour-baited trap for collecting C. putoria in the field. A series of field experiments was carried out in The Gambia to assess the catching-efficiency of different trap designs. The basic trap was a transparent 3L polypropyle...
Under certain circumstances, transposable elements (TE) can create or reverse mutations and alter the genome size of a cell. Sorghum (Sorghum bicolor L.) is promising for plant transposon tagging due to its small genome size and its low content of repetitive DNA. We developed a marker system based on targeted region amplification polymorphisms (TE-TRAP) that uses the terminal inverted repeats (...
Drosophila suzukii Matsumura (Diptera: Drosophilidae), a recent invasive pest of small and stone fruits, has been detected in more than half of the U.S. states, and in Canada, Mexico, and Europe. Upon discovery, several different trap designs were recommended for monitoring. This study compared the trap designs across seven states/provinces in North America and nine crop types. Between May and ...
A new trap, named the "H trap", was developed at Hellsgate Tsetse Research Station in South Africa for the simultaneous collection of live Glossina brevipalpis Newstead and Glossina austeni Newstead. Its design followed an evaluation of the responses of the two species towards traps that are used elsewhere in Africa for the collection of other tsetse fly species. These traps were found at Hells...
Since its introduction a few years ago, the linear ion trap Orbitrap (LTQ Orbitrap) instrument has become a powerful tool in proteomics research. For high resolution mass spectrometry measurements ions are accumulated in the linear ion trap and passed on to the Orbitrap analyzer. Simultaneously with acquisition of this signal, the major peaks are isolated in turn, fragmented and recorded at hig...
حدت استافیلوکوکوس اورئوس اساساً توسط پروتئین‌های مرتبط با دیواره‌ی سلولی و ترشح توکسین‌ها تعیین می‌گردد، که بیان آن‌ها تا حد زیادی توسط سیستم‌های تنظیمی دو جزئی (TCRSs) مثل سیستم‌های تنظیم ژنی فرعی (agr) و RAP-TRAP تنظیم می‌شود. تاکنون چهار واریانت آللی از agr (agr I-IV) و trap (trap 1-4) شناسایی شده است. برخی از گزارش‌ها اظهار داشت...
Monitoring traps are important components of integrated pest management applied against important fruit fly pests, including Bactrocera oleae (Gmelin) and Ceratitis capitata (Widemann), Diptera of the Tephritidae family, which effect a crop-loss/per year calculated in billions of euros worldwide. Pests can be controlled with ground pesticide sprays, the efficiency of which depends on knowing th...
