Evaluation of Protector 700 Wd in Controlling Tobacco Pests in Tanzania

In Tanzania, tobacco is an important cash crop benefiting most farmers and stakeholders. However, the crop is characterized by a low yield per unit area. Several factors are responsible for the low yield and quality of tobacco, among which are damages caused by the insects and other pests. Major insect pests of tobacco are cutworms (Agrotis spp), budworms (Heliothis virescens (F.)), (Lepidoptera Noctuidae) and aphids (Myzus persicae, Aphis tabaci) (Homoptera: Aphididae). These pests adversely affect crop growth, yield and leaf quality. In order to reduce insect attack in tobacco, applying pesticides is a critical management practices. In Tanzania, various pesticides have been approved for use in controlling the pests. Currently, farmers are using Bamethrine 2.5 EC to control the pests. The Pesticide named Protector 700 WG with an active ingredient imidacloprid 700 g/kg is a new product introduced in Tanzania during the 2021/22 crop season. Research trials were conducted in three research sites, namely Ulowa-Kahama, Tumbi-Tabora and Mtanila-Chunya, on Protector 700 WG efficacy in different rates, 15 g, 20 g, and 25 g each dissolved in 20 litres of water. The Protector 700 Wg was compared with the standard pesticide (Bamethrin 2.5 EC). Absolute control was also inclusive where the plot had no application of pesticides. The results showed that Protector 700 WG at all rates outweigh the commonly used pesticide. The difference in the number of pests between Protector 700 WG and Bamethrin 2.5 EC was significantly at P < 0.005 also, in dry and green weights, the yield was significantly different at P < 0.005. However, when yield and number of insects were compared among the rates of protector, there was no significant difference. From these results, farmers are advised applying Protector 700 WG at the rate of 0.15 kg/ha by dissolving it in 200 litres of water.

Duraphat与Fluor Protector抑制固定正畸矫治中牙釉质脱矿的比较研究

目的使用激光龋齿探测仪,比较两种含氟物Duraphat与Fluor Protector抑制固定正畸矫治中牙釉质脱矿的临床效果。方法选取接受直丝弓固定矫治的12~18岁青少年患者60例,采用自身对照法,试验组A右上前牙及前磨牙涂布Fluor Protector,试验组B左下前牙及前磨牙涂布Duraphat,对照组A左上前牙及前磨牙不使用任何药物,对照组B右下前牙及前磨牙仅涂布0.9%的氯化钠水溶液。分别于患者粘接正畸托槽前、粘接托槽后1个月、3个月使用激光龋齿检测仪测试受试牙牙面并记录荧光值(DD),应用单因素方差分析比较各组数值是否有统计学差异。结果①正畸托槽粘接后1个月、3个月时,2组涂布氟漆试验组的DD值均低于2组未涂布氟漆的对照组(P<0.05),说明Duraphat与Fluor Protector两种氟漆均显示了明显抑制釉质脱矿的能力。②正畸托槽粘接后1个月、3个月时,涂布Flour Protector的试验组A与涂布Duraphat的试验组B的DD值间比较差异无统计学意义(P>0.05),说明两种不同浓度的氟保护漆在抑制牙釉质脱矿的能力方面没有明显优劣。结论①接受固定矫治的患者存在釉质脱矿的易感性。②Duraphat与Fluor Protector两种不同浓度的氟化物对正畸过程中牙釉质的脱矿均有抑制作用,二者抑制脱矿的能力没有明显差异。③DIAGNOdent激光龋齿检测仪适合临床探查釉质的脱矿及龋损,对釉质表面的改变感应相当敏锐,帮助医师对龋病做出早期诊断,及早监控并采取合适的措施。

Evaluation of Geological Hazards for Landuse Planning in Nabq Protectorate, Southeastern Sinai Using GIS Techniques

Nabq protectorate is one of wonderful natural places in Egypt. It is characterized by diversity of bio-lives such as mangrove forests, coral colonies, wild life plants and migratory birds. Ongoing growth of tourism industries at Sharm El Sheikh northward into the Nabq protectorate causes severe hazards on its natural resources. The aim of the present study is to assess the present geo-environmental hazards in the Nabq protectorate. Assessment includes the analysis of satellite images, topographical, geological and other ancillary geological data using GIS technology. GIS data analyses indicate that the area is under threat from some of geo-hazards. Rough topography and mass wasting with high probability of flash flooding threaten different constructions in this area. The mobilization of coastal sand dunes, wave action and tidal currents are natural impacts on Nabq ecosystems, where moved dunes leave clay soils that are removed in some places by tropical storms increasing sea water turbidity that threaten the corals and other living organisms in the tidal flat region. The seismic activity hazard in the study area is usually active on lineaments extending parallel to the trend of the Gulf of Aqaba-Dead Sea transform fault where the Nabq protectorate occupies its southern segment. Unwise planning activities destroy the natural environmental resources in Nabq area by construction of new resorts on mangrove forests, coral colonies and raised beaches. Hazard assessment identifies land suitability and land use maps that are clearly exhibit models of traditional dams and buffer strips on coastal zone and highways as well as around the Bedouin communities which are worked on tourism and fishing. These maps are urgent in need of an assessment and rehabilitation program to mitigate geo-hazard.

Tuva, April 1914: Incorporation as a Russian Protectorate

Scholarly narratives concerning Tuva becoming a protectorate of Czarist Russia tend to contextualise this action within Russia’s rivalry with China.The 1911 Chinese Revolution provided an opportunity to annex Tuvan territory,culminating in Tuva becoming the final territorial expansion of the Empire before the Bolshevik Revolution.This research showcases that the Tuvan people were intent on much closer relations with newly independent Mongolia.The author argues that the Tuvan people belonging to the Turkic family of nations shared important values with and identified much more closely with Mongolia than Russia due to their common religion:Buddhism.The author stresses the fact that the increasing presence of Russians in Tuva in the mid 19th century resulted in the acknowledgement of two highly unfamiliar cultures and viewpoints.Utilising primary sources this work sheds light on the debates and choices Russia faced concerning Tuva and the opposition maintained by the new Mongol entity intent on unifying under its auspices peoples which were considered very close if not the same.This research highlights the Tuvan predicament as being located in more of a triangular contest than what is usually presented as a bilateral power struggle.
