TL;DR: The latest paradigms of applicability of these beneficial rhizobacteria in different agro-ecosystems have been presented comprehensively under both normal and stress conditions to highlight the recent trends with the aim to develop future insights.

TL;DR: In this paper, a total of 87 groundwater samples were collected from bore wells for two different seasons, viz., Pre monsoon and Post monsoon, and analyzed for major cations and anions.

TL;DR: In this paper, the contribution of open waste dumping in soil contamination and its effect on plant diversity in one of the renowned green cities of Pakistan is assessed and the diversity of vegetation was studied at both sampling sites.

TL;DR: In this article, the effects of thermal radiation using the nonlinear Rosseland approximation are investigated and a numerical analysis in connection with the boundary layer flow induced in a quiescent fluid by a continuous sheet stretching with velocity uw (x) ∼x 1/3 with heat transfer is performed.

TL;DR: In this paper, the authors investigated and compared the phytochemical screening, antioxidant and antimicrobial activities of different crude extracts from dry and fresh leaves of Datura metel L. The results showed that all the crude extracts did not show positive results for steroids and triterpenoid compounds.

TL;DR: In this article, the effect of maceration, Soxhlet and fractionation extraction from whole plant of Osbeckia parvifolia was studied for free radical scavenging and anti-inflammatory activities in vitro.

TL;DR: In this paper, the hydrophilic/hydrophobic ratio as a function of the hydric and hydrophobic contents removal by coagulation process is discussed, where it is well established that coagenation process could bring a reduction in dissolved organic carbon of around 30-60% by increasing the coagulant dose and optimising reaction pH.

TL;DR: Overall analysis of the antibacterial activity of tested samples revealed that the highest inhibitory activity was produced by Litchi chinensis (15 ± 0.55 mm) against S. pyogenes.

TL;DR: In this paper, the authors evaluated both immature and mature corn silks for their variations in nutritional compositions, mineral content and antioxidant capacity, and found that the mature silks contained higher composition of ash (5.51%), carbohydrate (29.74%), protein (12.96%), and total dietary fiber (51.25%) than the immature silks, but the difference was not significant.

TL;DR: It was found that despite the natural variability in the chemical content of ipomoea growing in different locations, certain extract–metal stoichiometries can be identified which give strikingly reproducible results in terms of the size and the shape of the SNPs.

TL;DR: The putative mutant C1M26 produced a larger amount of cellulase in comparison to wild type C1 strain after mutagenesis with N-methyl-N′-nitro-N-nitrosoguanidine (NTG) as a mutagenic agent.

TL;DR: Investigation of the lethality as well as biochemical and histopathological effect of Egyptian cobra crude venom at a sublethal dose found that such injury could be considered among the factors that lead to death caused by N. haje venom.

TL;DR: Oral vitamin E administration has a hepatoprotective role against K2Cr2O7-induced hepatotoxicity in rats and resulted in normal hepatic histological and cellular contents.

TL;DR: In this article, the authors evaluated the quality of drinking water and qualitative classification of potable water in Ardabil plain aquifer using data driven techniques of kriging and fuzzy logic modeling.

TL;DR: It has been identified that Tedh, well-known as a therapeutic agent to treat various illness and insects’ repellent plant to drive-away insect vector of diseases, could serve as a potent personal protective tool to minimize the burden of insect-transmitted diseases particularly malaria in the future.

TL;DR: In this paper, the bottle beam configuration was used for the creation of a novel atom optical dipole trap called the bottle atom trap, which is a nice candidate for trapping Bose-Einstein condensates and may serve as an optical tweezer mechanism potentially useful for trapping micron-sized dielectric particles.

TL;DR: An efficient and direct procedure for the synthesis of 4,6-diphenyl-3,4-dihydropyrimidine-2(1 H )-thione derivatives by condensation of 1,3-diaryl-2-propen-1-ones (chalcones) and thiourea in ethanol at 65°C using triphenylphosphine (PPh 3 ) as a catalyst is reported as discussed by the authors.

TL;DR: In this article, the concavity and convexity structure of non-negative linear maps are used to obtain operator inequalities for the Khatri-Rao product of two or more positive definite matrices.

TL;DR: The reduction in the total viable vibrio counts in the anesthetized fish indicated that the vibrio were sensitive to the thymeOil, and thyme oil produced higher non-specific immune enhancements.

TL;DR: Gellan composite gels were comparatively weaker and possessed more viscous behavior compared to those of gelatin-based due to different gelling mechanisms, in which the latter had yielded denser network structures as compared to the former.

TL;DR: In this article, the authors introduce and investigate some new classes of mappings called contra-M-continuous mappings and almost-contraditional mappings via M-open sets.

TL;DR: In this article, the traveling-wave solutions for the 6-order thin-film equation were obtained, where related balance numbers are not the usual positive integers, and exact traveling wave solutions such as solitary wave solutions were obtained when parameters are taken at special values.

TL;DR: Analysis of cytotoxic potential of methanolic leaf and bark extracts against human cervical cancer cell line (SiHa) suggested that extracts and compounds from this plant could be useful for preventing and treating human gynaecologic cancer disease.

TL;DR: The main purpose of as mentioned in this paper is to synthesize novel heterocyclic derivatives of fatty acids which are also biologically important, such as phthalazindiones and pyrazolones.

TL;DR: In this paper, the effect of organic selenium supplementation vs inorganic Se was evaluated in 24 pregnant camels, which were subjected to three treatment groups starting one month before delivery (control without Se, non-organic bolus, organic Se).

TL;DR: Application of insecticides caused a decrease in the attack rate and an increase in the handling time of exposed bugs compared with the control, suggesting that the adverse effect of these insecticides on A. spinidens should be considered in integrated pest management programs (IPM).

TL;DR: The use of enzyme inhibitors from different plant sources may serve as an important pest control strategy via plant breeding programs and identification of genes responsible for these inhibitor proteins could be a first step to provide a resis- tant variety of olive.

TL;DR: Investigation of the protective effects of N-Acetylcysteine on propionic acid-induced neurotoxicity in rat pups found a significant increase in lactate dehydrogenase activity, decrease in glutathione levels, and decrease in sodium levels.

TL;DR: Replacement of 15% protein from soybean Meal in Diet II was feasible for the stinging cat fish, Heteropneustes fossilis and no significant differences in growth parameters were found in fish fed soybean meal-based diets compared to those fed control diet.

TL;DR: In this paper, the effects of adiabaticity of electron and ion fluids, concentration of negatively/positively charged static dust particles and ion temperature to electron temperature ratio on the phase shift are studied.
