Objective: To test the relative efficacy of pyriproxyfen and methoprene on mortality,deformity, inhibition and emergence to adult stages of Culex quinquefasciatus and Aedes ***: Serial dilutions(0.01–0.05 mg/L) of methoprene, pyriproxyfen 0.5 water dispersible granules(WDG) and pyriproxyfen 1.0 WDG were used to assess mortality and inhibition of 3rd instar larvae of Aedes albopictus and Culex quinquefasciatus. Each concentration and control was replicated four times in completely randomized *** on larval mortality, growth inhibition, deformities and adult's emergence was recorded weekly. On the basis of best comparative performance, the efficacy of pyriproxyfen 1.0 WDG at 0.1 g/m3 was also tested in the field by collecting treated water samples monthly for 1–6 months after field application. Twenty five 3rd instar larvae of Aedes and Culex spp. of the same cohorts were used for bioassays and compared with larvae in control cups containing 1 L of untreated tap ***: Results revealed variations in fatality of different insect growth regulators(IGRs) to the 3rd instar larvae of Culex and Aedes mosquitoes. Among the IGRs, pyriproxyfen 1.0 WDG was found best that exhibited significantly high emergence inhibition against Culex and Aedes spp. Based on the results, the IGRs were classified in terms of the tested parameters in order of pyriproxyfen 1.0 WDG > pyriproxyfen 0.5WDG > methoprene. In case of field studies, pyriproxyfen 1.0 WDG, pool data of the entire target treated sites showed minimum adult emergence from water sampled of habitats treated with 0.1 g/m3 of pyriproxyfen 1.0 ***: It is thus concluded that IGRs can be utilized as environment friendly control measures for Culex and Aedes spp. of mosquitoes on small and large scale. This will reduce the use of conventional insecticides by the public health authorities and help in reducing selection pressure of insecticides.

Cauliflower is popular vegetable in Pakistan and it is severely attacked by Pieris brassicae (L). There are different cauliflower cultivars available in this area. The aim of this study was to determine the developmental response of Pieris brassicae on ten cauliflower cultivars. An experiment was conducted during 2012-13 at the Entomology section of the Agriculture Research Institute Tarnab Peshawar under laboratory conditions of 20°C ± 2°C, 50% ± 5% RH and 12:12h photoperiod. Pieris brassicae eggs were collected from a cauliflower field ARI Tarnab and the larvae placed after hatching on fresh leaves often cauliflower cultivars. The results showed that the larval development of P. brassicae was short (35 days), longer larval length (32.41 mm), larval mortality was low (6.6%) and pupal weight was high (0.50 g) on Clima cultivar. On the other hand, a longer larval developmental period (37 days), higher larval mortality (86.66%), shorter larval length (24.55 mm) and lower pupal weight (0.42 g) were recorded on cultivar AX-2034.

A significant decrease was observed in PAIg G and PAIg M in these subjects. Inverse correlation was found between platelets count and PAIg G/PAIg M among the subjects studied. In the platelets elution from ten subjects, anti-dengue virus immunoglobulin G and immunoglobulin M were observed. PAIg G and PAIg M with inclined levels were higher in dengue hemorrhagic fever than the classical dengue fever. In the development of dengue hemorrhagic fever PAIg M inclined level was independently associated with high specificity, showing a possible indication of dengue hemorrhagic ***: This study suggests that in secondary dengue virus infection, the PAIg G and PAIg M levels, and the activity of anti-dengue virus play key roles, both in the development and severity of the disease.

在过去的十年可以看到,数字图像和视频内容生成和分享的数量得到了爆炸式的增长。这种发展归因于图像和视频采集,压缩,存储和通信技术取得了巨大的进步。现在,可视通信已成为信息交流的动态模式。多媒体内容的传播对我们生活的影响已超过以往任何时候。毫不夸张的说,多媒体通信已经成为无线网络服务提供商提供服务的主要推动力,或者说现在网站为交流打开一种新局面,就像优酷。多媒体通信一般涵盖音频、图像和视频通信。图像和视频通信系统的主要目标是在给定速率和信道状况的前提下,实现尽可能好的视觉效果。目前,焦点限制为图像通信系统。为了优化通信系统的组件,以最大限度地提高感知质量,使用一个好的质量评估方法是很重要的。尽管早就认识到均方误差(MSE)对感知质量不能做出准确的评估,但它一直普遍用在图像通信系统的各个组件的设计中。在图像质量评价(IQA)领域的最新研究已经促进了强大的新算法的开发。其中几个新算法包括结构相似(SSIM)指数、可视信息保真(VIF)准则、以及视觉信噪比(PSNR)。在本文,数字图像压缩原理已得到DCT算法和利用blockproc函数的新算法的验证。图像压缩主要在不影响图像质量的情况下减少文件的大小。对于研究人员来说,通过不断处理,使重构图像的质量接近原始图像,仍是一个挑战。离散余弦变换(DCT)是非常有名的压缩技术,并被广泛地用于压缩图像。我们知道,在某些情况下DCT压缩算法重建的图像会出现朦胧或模糊的现象,特别是大尺寸图像。为了克服这些问题,出现了许多纠正朦胧或模糊的技术和算法。在本文中,我们提出通过使用blcokproc函数来压缩图像的技术。此外,运用blockproc函数的DCT算法可以作为图像处理去模糊的新方法,可以在图像处理去模糊工具使用。Blockproc处理方法逻辑上可用来处理任意大的图像。它支持一个文件到文件的工作流,从而不需要输入或输出图像完全包含在存储器中。各块的处理是一独立的操作且并行处理。相比于DCT变换,进一步减少了重建图像文件的大小。对图像更小的部分进行处理,而无需将整个图像加载进一个MATLAB变量。我们做了使用DCT和blockproc压缩MATLAB代码,然后在图像质量、图像压缩比、峰值信噪比(PSNR),均方误差(MSE)和结构相似性的基础上进行对比,评估图像整体质量。因此,连同blockproc函数的DCT方法是图像处理的最佳方法。此外,它是一个新的方法。这对大量图像压缩应用做进一步研究有很大帮助。
