Field studies were conducted at Hisar during Kharif, 2009-2010 and 2010-2011 under natural and unsprayed condition. RCH 134 Bt, HS 6 (non Bt), H 1117 and Ganganagar Ageti (non Bt) were selected for the studies. The experiment was laid down in Randomized Block Design replicated thrice having plant spacing 67.5 × 60 cm. Among the bollworms, Erias spp. exhibited positive correlation with rainfall, minimum temperature and relative humidity morning hours significantly at 5 percent level whereas Helicoverpa and Pectinophora displayed positive relations only with evening hours relative humidity significantly while Spodoptera were significantly positive correlated with relative humidity of morning and evening hours. Bollworm complex was negatively correlated with all the weather parameters employed to study although being non-significant in case of rainfall, maximum and minimum of temperature, morning and evening hours of relative humidity. Among the sucking pests, leafhoppers, whitefly, thrips and aphids population showed significantly negative correlation with weather parameters. The comparison of natural bio-agents in cotton hybrids under study revealed that overall mean population of natural enemies were higher in Bt cotton hybrid as compared to non-Bt. These results confirm that use of genetically modified (Bt) cotton in lieu of conventional genotypes could positively impact non-target and beneficial insect species by preserving their host populations.

BACKGROUND： Thiamine is an essential cofactor associated with several enzymes in energy metabolism and its deficiency may lead to neurological deficits. Current research evaluated the biochemical and molecular changes in TCA cycle enzymes using the mitochondrial fraction of the brain following thiamine deficiency （TD） in mice. METHODS： The investigation was carried out on Swiss mice （6-8 week old） allocated into three groups. First group was control; second and third group were made thiamine deficient for 8 and 10 days. RESULTS： Current study showed that alpha-ketoglutarate dehydrogenase （KGDHC）（thiamine-dependent enzyme） level found to be significantly reduced in experimental groups as compared to control group. In comparison to control group, a significant decrease in the succinate dehydrogenase （SDH） activity was calculated in group II and group III （p 〈 0.0001） mice. Diminished enzymatic activity of fumarase and MDH enzyme in thiamine deficient groups exposed for 8 and 10 days was calculated as compared to control group. The expression analysis of different genes governing TCA cycle enzymes in different experimental groups showed that there was a negotiable change in the expression of fumarase and DLD （dihydrolipoyl dehydrogenase- E3 subunit of KGDHC） whereas a declined in the expression of SDH and two subunits of KGDHC i.e. OGDH （2-oxoglutarate dehydrogenase- E1 subunit of KGDHC） and DLST （dihydrolipoyllysine-residue succinyltransferase- E2 subunit of KGDHC） was observed as compared to control group. CONCLUSIONS： Hence, current findings strongly entail that TD promotes alteration in energy metabolism in brain mitochondria which will decline the neuronal progression which may lead to neurodegenerative diseases such as Alzheimer＇s diseases.

The utility of microorganisms for solubilizing the unavailable forms of potassium(K) from soil has led to renewed interest in fabrication of rapid and sensitive plate assays for their isolation and screening. The present study developed a modified plate assay and compared it with previously reported methods for the isolation and screening of K-solubilizing bacteria. The newly developed plate assay is based on improved visualization of halo zone formation around the colonies on agar plates, through inclusion of an acid-base indicator dye, bromothymol blue(BTB), to modify the previously reported Aleksandrov medium. The halo zone exhibited a significant correlation(R = 0.939) with K released in liquid medium. The visualization of potential K solubilizers was improved using this method, which would help in detection of weak/non-acid producers based on secretion of organic acids in the medium. Organic acids in plate diffuse radially and form halo zones in response to reaction with the acid-base indicator dye BTB. Furthermore, K solubilization on plates with this method can be observed within 48–72 h, against the incubation time of 4–5 d needed in the earlier method. Therefore, the newly developed protocol for the plate assay was time saving, more sensitive, and beneficial in comparison to the previously reported Aleksandrov plate assay.

3D打印可以改变现有的生产方法,是第四次工程革命中的一项现代技术。它从成型原理上提出了分层制造、逐层叠加成型的新颖生产方法,从根本上简化了制造工艺,实现了大规模定制生产。然而,这一新技术仍存在许多问题。除了纯石墨烯外,sp^(2)碳具有好的亲水性,3D打印难度较小。sp^(2)碳还可在3D打印中的各种阶段应用。纯石墨烯的疏水性使其难以在水系介质中打印和加工。毛细管油墨的发展使得纯石墨烯的3D打印成为可能。本文综述了sp^(2)碳的3D打印技术的最新进展。首先简要概述了3D打印技术,随后概述了sp^(2)碳的3D打印及其在各种方面的应用。最后,讨论了这一新领域的发展前景和机遇。

下一代电子产品的飞速发展对热管理提出了更高的要求。初始石墨烯的导热性是铜的13倍。本文通过快速热处理化学气相沉积(RTP-CVD)法制备了具有大sp^(2)结构域的单层、双层和多层石墨烯(SLG、BLG、FLG),进一步通过低浓度H_(2)还原制备了高导热石墨烯。在1000℃下生长25 min制备出SLG,利用拉曼光谱和透射电子显微镜(TEM)研究了石墨烯的品质。为了验证RTP-CVD法生成的石墨烯的散热能力,将其作为2TB固态硬盘的散热器,通过红外热成像仪进行了研究。结果证明,RTP-CVD生长的石墨烯用于消费电子产品的热管理测试时性能表现优异。SLG显示温度(最高)比商用铜散热器低5℃,SLG的散热能力比商用铜散热器快200倍左右。综上,利用RTP-CVD法制备的轻质的柔性石墨烯可以成为下一代5G设备和消费电子产品热管理的更好选择。
