Integrated multi-trophic aquaculture (IMTA), farming of species from different trophic levels and with complimentary ecosystem function, is regarded as a suitable approach to develop a sustainable aquaculture system. In order to establish an IMTA system, a study was carried out in Sindhudurg District, Maharashtra, India for selected tropical brackish-water species. Two equal sized pens (250 m2) were constructed for IMTA and control respectively in each land based system and open water cages were set in the estuary. Different combinations of fed species (Chanos chanos, Etroplus suratensis, Mugil cephalus, Penaeus indicus) and an extractive crop (Crassostrea madrasensis) were stocked in IMTA experimental system whereas monoculture of P. indicus served as control. Water quality characteristics were found to be within the admissible limits. Soil organic carbon was found to be lesser in the IMTA system compared to control. The productivity of IMTA system was higher than control: 3250 kg h-1 vs 2000 kg ha-1. Further, income and benefit-cost ratio was found to be higher in IMTA pens. The present study concludes that IMTA is a possible option for system diversification as well as species diversification without compromising economic profitability of culture.

Okra is one of the most important summer vegetables in South Asian countries including Nepal. However, the damage by insects like Jassid (Amrasca biguttula Ish.) and whitefly (Bemisia tabaci Guen) has resulted in significant reduction of its production. An experiment was conducted based on intercropping taking okra (Abelmoschus exculentus L. Moench) as the main crop in Arghau, Lekhnath-27, Kaski, Nepal from March 4 to May 24, 2018. The intercrops used were coriander (Corriander sativum), carrot (Daucas carota), fennel (Foeniculum vulgare) and parsley (Petroselinum crispum). The population of jassid and whitefly was recorded from three leaves representing the different strata (bottom, middle and top) of the vegetative parts; and related yield parameters were also observed to correlate with the level of population incidence of these pests. Least numbers of jassids (5.50±0.29, 6.94±0.43, 8.00±0.41 and 3.69±0.76) were observed respectively at 30, 40, 50 and 60 days after sowing (DAS) in okra+ coriander. Likewise, okra + coriander intercropping was effective in inhibiting the population of whitefly (7.50±0.59, 8.56±0.19, 10.25±0.66 and 7.06±0.42) at 30, 40, 50 and 60 days after sowing (DAS) respectively. In contrary, the highest number of jassids and whiteflies were observed in okra + parsley and control (okra only). Both pod length (cm) and yield (t/ha) were the highest (17.92±0.57 and 28.20±0.49 respectively) in okra + coriander and were the lowest (16.42±0.21 and 27.58±0.39 respectively) in okra + carrot. The benefit-cost ratio was in order okra + coriander > okra + carrot > okra + fennel > okra + parsley > control (okra only). Among the different intercrop combinations, the okra + coriander was found most effective that could be suggested as one of the alternative strategies to limit the population of pests; jassid and whitefly in okra.

A field experiment was conducted during kharif, 2019 at Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad. The experiment done with twelve treatments and three replications. The study was taken to find out which herbicide mixture most effective in controlling of weeds leads to maximum yields with higher benefit cost ratio. The results revealed that, application of herbicide mixture florpyrauxifen-benzyl + cyhalofop-butyl 10% EC 150 g/ha PoE fb hand weeding at 40 days after transplanting (DAT) gave higher yields and net returns with high benefit cost ratio (B: C) which was statistically on par with minimum competitive plot. Unweeded plot yield was deviated about 48 % compare to florpyrauxifen-benzyl + cyhalofop-butyl 10% EC 150 g/ha PoE fb hand weeding at 40 days after transplanting.

Pod fly [Melanagromyza obtusa (Malloch)] is a key biotic constraint for productivity in subsistence crop protection pattern; its damage varies up to 80%; has been estimated about US $ 256 million annually. The research trial was accomplished at Research Farm of SASRD, Nagaland University during Kharif 2011 and 2012 in order to evaluate the new molecules against pod fly. The experiment was consisted 6 treatments (Trizophos 500 g ai. ha-1, Emamectine benzoate 11 g ai. ha-1, Emamectine benzoate 11 g ai. ha-1 + Acetamiprid 30 g ai. ha-1, Flubendiamide 47 g ai. ha-1, Chlorantraniliprole 40 g ai. ha-1 and Spinosade 75 g ai. ha-1) compare with control. The lowest pod damage (9.7% and 9.3%), lowest grain damage (5.3% and 5%) and highest grain yield (1202 kg ha-1 and 1209 kg ha-1) were obtained from Chlorantraniliprole followed by Emamectine benzoate+ Acetamiprid, Spinosade, Emamectine benzoate, Flubendiamide, Trizophos and all the treatments were significantly superior over control. The highest B: C ratio reward (1:4.24) was obtained from Chlorantraniliprole. The results indicated that Chlorantraniliprole was more effectual against pod damage, grain damage, yield and B: C ratio. The safer chemical control methods reduce the pod damage, grain damage and higher yield with high benefit: cost ratio, so therefore chemical control popularizes as an effective, practical alternative and makes lucrative cultivation of pigeon pea.

Electronic skin (e-skin) is pursued as a key component in robotics and prosthesis to confer them sensing properties that mimic human skin. For pressure monitoring, a great emphasis on piezoresistive sensors was registered due to the simplicity of sensor design and readout mechanism. For higher sensitivity, films composing these sensors may be micro-structured, usually by expensive photolithography techniques or low-cost and low-customizable molds. Sensors commonly present different sensitivities in different pressure ranges, which should be avoided in robotics and prosthesis applications. The combination of pressure sensing and temperature is also relevant for the field and has room for improvement. This work proposes an alternative approach for film micro-structuration based on the production of highly customizable and low-cost molds through laser engraving. These bimodal e-skin piezoresistive and temperature sensors could achieve a stable sensitivity of −6.4 × 10−3 kPa−1 from 1.6 kPa to 100 kPa, with a very robust and reproducible performance over 27,500 cycles of objects grasping and releasing and an exceptionally high temperature coefficient of resistance (TCR) of 8.3%/°C. These results point toward the versatility and high benefit/cost ratio of the laser engraving technique to produce sensors with a suitable performance for robotics and functional prosthesis.

The COVID-19 pandemic has forced healthcare systems around the world to adopt telemedicine at an unprecedented rate. Visits to telemedicine have increased to provide access and maintain continuity of care. Internet access has almost become a necessity, and new technologies allow for the easy flow of data from patient to doctor and vice versa. Doctors of all specialties were forced to adapt to the pandemic and emerging conditions. The provision of surgical services and the learning ability of surgeons are particularly disrupted, and the pediatric surgical community is not exempt. During the pandemic, telemedicine proved to be a viable and safe technique for providing health services. In an environment of a health system that is constantly facing a shortage of resources, effective telemedicine placement can come with a high benefit-cost ratio and quality of care, while ensuring patient satisfaction.
