IoT devices have limited resources in terms of power, processing capabilities, bandwidth etc. but the existing set of protocols were not designed for such constraints. Gartner Inc. forecasts that the total number of connected things will reach 20.4 billion by 2020. The specific needs of the IoT domain should be addressed considering the huge scale of implementation and its influence on public life. There is a need of a standardized layered architecture and protocol suite designed specifically to meet the need of IoT applications. Various consortia are working on developing IoT standards majorly driven by government agencies, standards bodies and industry giants. We present the various initiatives at international level and at national level, in India, towards developing IoT standards. Although the world still waits for a unified IoT standard but lately major efforts have taken place at international level, through collaboration and liaison agreements, towards the convergence of various standardization efforts. Such developments raise the hope of universal IoT standards in the near future.

E-commerce has created easiness and innovativeness in humans’ life. Online consumer buying behavior is not like a physical market having ability to touch, analyze, and thereafter shop the products. This study explores the effect of few variables, derived from existing literature. Those variables are perceived benefits, domain specific innovativeness, and shopping orientations, i.e., impulse-purchase orientation, brand orientation and quality orientation. The data was collected by mean of the questionnaires. The findings indicated that domain specific innovativeness and shopping orientations have positive impact on consumers’ buying behavior towards online shopping. Therefore, consumers are showing an interest to online shopping because of recent development of electronic stores in Pakistan.

Seven fungicides viz., four systemic (Propiconazole, Azoxystrobin, Thiophanate methyl and Carbendazim) and three non-systemic (Mancozeb, Captan and Zineb) at four concentrations i.e. 50, 100, 150 and 200 ppm and seven plant extracts viz., Datura strumarium (Jimson weed), Allium sativum (Garlic), Azadirachta indica (Neem), Zingiber officinale (Ginger), Ocimum sanctum (Tulsi), Calotropis gigantea (Aak) and Eucalyptus chamadulonsis (Eucalyptus) also at four concentrations i.e. 5, 10, 15 and 20 per cent were evaluated through poison food technique. Seven bio-control agents viz., Trichoderma harzianum, T. viride, T. koningii, T. hamatum, T. atroviride, Aspergillus niger and A. flavus were also evaluated in this study through dual culture technique. Among the systemic fungicides, Propiconazole was proved to be highly effective and recorded cent per cent inhibition at their all concentrations while among the nonsystemic, Mancozeb was proved to be effective at their all concentrations but recorded 100 per cent inhibition only at their higher concentration i.e. 400 ppm. Among different plant extracts used, Azadirachta indica (Neem) was significantly inhibit the mycelial growth of pathogen at all concentrations followed by Datura strumarium (Jimson weed) and Calotropis gigantea (Aak). Of all bio-control agents, highest inhibition of radial growth of test fungus was recorded in Trichoderma harzianum (80.37%) followed by T. viride (71.48%) and T. koningii (77.41 %). However, T. hamatum (27.41%) was least effective in this study.

In this beneficial relationship, the host plant provides necessary and other basic life supporting materials to the fungi, whereas fungi in-return helps to available essential minerals and life supporting nutrients especially P2O5 to the host plant. Instead of providing major nutrients, Mycorrhiza also acts as bio protectants against pathogens and toxic stresses during biological interaction. But nowadays, due to the changing environment and indiscriminate use of pesticides, pose a great menace to the existence of mycorrhizal species. Therefore, it is required to spread awareness in relation to save mycorrhizal fungi from extinction.

The cause of harmonics distortions in these locomotives is due to the increase in the use of power electronics devices, wherein the introduction of GTO and IGBT-based locomotives have brought up technological advancement in railways, while on the other hand it have its own certain limitations as well. Hence, the study was carried out on oil cooling blowers and traction motor blowers used in a locomotive which uses GTO and IGBT-based converters. This paper presents the analysis of current harmonics which were recorded using a current clamp and DSO.

Meeting this goal is not going to be easy; India faces a shortage of attractive capital to meet its renewable energy targets. Investors face two major risks to investing in India, including in renewable energy: currency risk and off-taker risk. Off-taker risk is a key contributor to the overall credit risk of power projects in India, adding as much as 1.07 percentage points of additional risk premium to the cost of debt for renewable energy projects. Mitigating the off-taker risk requires long-term structural fixes focused on addressing the systematic failures of the utilities sector. However, short-term solutions are still needed to mitigate the off-taker risk. One short-term solution to mitigate off-taker risk is a government-sponsored payment security mechanism that would provide assurance that the payments under power purchase agreements are made on time. In this article, the authors lay out a framework for designing a payment support mechanism for single off-takers, to effectively achieve target credit enhancement in the beneficiary projects. They find that, barring outliers, the average payment security support in their sample turns out to be 12 months, or 10%–20% of capital expenditure, which is significant. They also discuss avenues for future research. TOPICS: Real assets/alternative investments/ private equity, risk management, project finance, emerging markets

RF signal associated with wireless networks suffers from many propagation losses. It becomes essential to estimate losses at different locations, in the intended coverage area, to attain the desired performance seamlessly. It helps in the optimal device placement in the wireless networks. In the application, in addition to the propagation losses, there is a need to estimate the loss induced by the presence of smoke and fire, individually, in an indoor environment. This paper first deals with the design of a heatmap generating tool, in MATLAB, which gives the approximate signal strength at different locations on a given floor for a given transmitter. Then the paper discusses the formation of plasma in fast flaming fires and presents the path loss due to it. This path loss is incorporated in the heatmap generating tool and a heatmap is generated for our office ground floor for the case of a flaming fire. The paper also describes a testbed, setup in our office premises, to study the scattering loss caused by smoke particles.

Patients generally present in childhood with multiple episodes of variceal bleed and EHPVO is the predominant cause of paediatric portal hypertension (PHT) in developing countries. It is a pre-hepatic type of PHT in which liver functions and morphology are preserved till late. Characteristic imaging findings include multiple parabiliary venous collaterals which form to bypass the obstructed portal vein with resultant changes in biliary tree termed portal biliopathy or portal cavernoma cholangiopathy. Ultrasound with Doppler, computed tomography, magnetic resonance cholangiography and magnetic resonance portovenography are non-invasive techniques which can provide a comprehensive analysis of degree and extent of EHPVO, collaterals and bile duct abnormalities. These can also be used to assess in surgical planning as well screening for shunt patency in post-operative patients. The multitude of changes and complications seen in EHPVO can be addressed by various radiological interventional procedures. The myriad of symptoms arising secondary to vascular, biliary, visceral and neurocognitive changes in EHPVO can be managed by various radiological interventions like transjugular intra-hepatic portosystemic shunt, percutaneous transhepatic biliary drainage, partial splenic embolization, balloon occluded retrograde obliteration of portosystemic shunt (PSS) and revision of PSS.

Intramural accumulation of lipid-laden macrophages and acute and chronic inflammatory cells is the hallmark of the disease. The xanthogranulomatous inflammation of the gallbladder can be very severe and can spill over to the neighbouring structures like liver, bowel and stomach resulting in dense adhesions, perforation, abscess formation, fistulous communication with adjacent bowel. Striking gallbladder wall thickening and dense local adhesions can be easily mistaken for carcinoma of the gallbladder, both intraoperatively as well as on preoperative imaging. Besides, cases of concomitant gallbladder carcinoma complicating XGC have also been reported in literature. So, we have done a review of the imaging features of XGC in order to better understand the entity as well as to increase the diagnostic yield of the disease summarizin...
