A Quality Hybrid Service Discovery Protocol
Hybrid protocol combines the advantages of proactive and reactive routing in adhoc network. The routing is initially established with some proactively prospected routes and then serves the demand from additionally activated nodes through reactive flooding. In this paper we propose A Quality Hybrid Service Discovery Protocol (QHSDP) for discovering services. A broadcast mechanism is used to get the service and routing information of the nodes present inside the zone. The routing and service information reduces the packet flooding in the network hence reducing collision and increasing packet delivery efficiency. Reduced control packets in turn reduces the battery power consumption. A query message is bordercasted through the peripheral nodes to the nodes outside the zone. This makes the discovery procedure more sclable, hence increasing the node’s coverage and reducing the latency in the proposed technology compared to the existing technolog
Murraya Paniculata Mediated Synthesis Of CdS Nanoparticles For Potent Biomedical Applications
The leaf extract of Murraya paniculata (MPL) is used to create cadmium sulphide nanoparticles, or CdS NPs and the reducing and stabilizing agent is plant extract. A crucial capping agent in nano production is played by phytochemicals. Analytical methods such as
XRD and FTIR are used to characterize CdS NPs. The biomedical applications of prepared CdS NPs were examined, including their anticancer, antifungal, and antibacterial properties. The antibacterial performance was carried out with S.flexneri, C.perfringens, S.typhimurium, and E.faecalis which were all susceptible to the antibacterial action of CdS NPs. At 150µg/ml, S.flexneri and E.faecalis showed a maximum zone of inhibition is 20mm. In addition, A.niger and C.albicans were used to test the antifungal activities, results shows the concentration of 400 µg/ml CdS NPs inhibited the growth of A.flavus (16mm). By using the NRU assay, it was found that the biosynthesized CdS NPs exhibited cytotoxic action against the MCF-7 cell line. Analysis using the NRU assay revealed that treating cell lines with increasing concentrations of NPs had lethal effects. The 24-hour treatment's IC50 was found to be 153.2 µg/ml
JUNGBRUNNEN1 confers drought tolerance downstream of the HD-Zip I Transcription factor AtHB13
Low water availability is the major environmental factor limiting growth and productivity of plants and crops and is therefore considered of high importance for agriculture affected by climate change. Identifying regulatory components controlling the response and tolerance to drought stress is thus of major importance. The NAC transcription factor (TF) JUNGBRUNNEN1 (JUB1) from Arabidopsis thaliana extends leaf longevity under non-stress growth conditions, lowers cellular hydrogen peroxide (H2O2) level, and enhances tolerance against heat stress and salinity. Here, we additionally find that JUB1 strongly increases tolerance to drought stress in Arabidopsis when expressed from both, a constitutive (CaMV 35S) and an abiotic stress-induced (RD29A) promoter. Employing a yeast one-hybrid screen we identified HD-Zip class I TF AtHB13 as an upstream regulator of JUB1. AtHB13 has previously been reported to act as a positive regulator of drought tolerance. AtHB13 and JUB1 thereby establish a joint drought stress control module.Fil: Ebrahimian Motlagh, Saghar. University of Potsdam; Alemania. Max Planck Institute of Molecular Plant

Nonisothermal crystallization kinetics and microstructure evolution of calcium lanthanum metaborate glass
This paper reports results on the crystallization kinetics of 35.5CaO-7.25La(2)O(3)-57.25B(2)O(3) glass under nonisothermal conditions based on the studies carried out from the differential thermal analysis upon using various well-established models. The crystalline phases formed during the optimized ceramization process have been confirmed from the X-ray diffraction. The activation energies of the first (formation of CaLaB(7)O(13)) and second (formation of LaBO(3)) crystallization events have been estimated using the conventional methods of Kissinger, Augis-Bennett, Ozawa, and Matusita, and the results are found to be in good agreement with each other. The Avrami exponents that are determined by these models for the crystallization of CaLaB(7)O(13) and LaBO(3) are found to be in the range of (1.81-2.35) and (4.03-4.65), respectively. This indicates that the formation of CaLaB(7)O(13) is dominated by a surface crystallization, whereas LaBO(3) is formed by three-dimensional bulk crystallization with an increased rate of nucleation. This observation is further validated by microstructural investigation, which shows the formation of CaLaB(7)O(13) phase as a surface layer and a bulk crystallization of LaBO(3) in optimally ceramized samples
Plant growth promoting bacteria Bacillus subtilis promote growth and physiological parameters of Zingiber officinale Roscoe
Ginger (Zingiber officinale Roscoe) is an important medicinal crop grown for its aromatic rhizome which is used as a spice, food, flavouring agent and medicine. It has been characterised for its hypoglycemic, hypotensive, antioxidant and antibiotic properties. This study was conducted to determine the impact of plant growth-promoting potential of bacterial strain Bacillus subtilis L2 on plant growth and physiological properties of ginger. The experiment was carried out in randomised block design with three replications in pot experiments. The plants were grown in greenhouse conditions for three months. The results showed that at 8 and 12 weeks after planting (WAP) bacterial inoculation increased plant height, leaf length, number of leaves per plant and leaf width. Inoculation with B. subtilis L2 significantly increased plant height by 16, 20 and 18% compared to control at 4, 8 and 12 WAP. At 8 and 12 WAP, leaf length significantly raised by B. subtilis L2 as compared to uninoculated control. B. subtilis L2 significantly increased the number of leaves per plant and leaf width by 30 and 21% respectively when comparing with non-inoculated plants at 8 WAP. The percentage increase in chlorophyll content resulted from the inoculation with B. subtilis L2 over the control was 10.5%, 15.5% and 18.4% at 4, 8 and 12 WAP respectively. It is concluded that there is a significant positive effect of inoculation with B. subtilis L2 on the growth of ginger. B. subtilis L2 strain can be used as a potential agent or bio-fertiliser for stimulation of ginger growth
Does U.S. Federal Employment Law Now Cover Caste Discrimination Based on Untouchability?: If All Else Fails There Is the Possible Application of Bostock v. Clayton County
This article discusses the issue of whether a victim of caste discrimination based on untouchability can assert a claim of intentional employment discrimination under Title VII or Section 1981. This article contends that there are legitimate arguments that this form of discrimination is a form of religious discrimination under Title VII. The question of whether caste discrimination is a form of race or national origin discrimination under Title VII or Section 1981 depends upon how the courts apply these definitions to caste discrimination based on untouchability. There are legitimate arguments that this form of discrimination is recognized within the concept of race discrimination or national origin discrimination under Title VII or race discrimination under Section 1981. However, if courts reject these conclusions, the approach adopted by the Supreme Court in its June 2020 decision in Bostock v Clayton County would provide another potent legal argument for recognizing such discrimination.
The Bostock approach avoids the question of whether caste discrimination based on untouchability is a form of national origin or racial discrimination. This approach draws on the Supreme Court’s recognition that the “but-for” causation standard applies under both Title VII and Section 1981. The but-for test directs us to change one thing at a time and see if the outcome changes. If it does, we have found a but-for cause. And, multiple but-for causes can exist. Applying this approach to intentional employment discrimination against gays, lesbians or transgender individuals, the Supreme Court pointed out that such a person’s sex is inextricably intertwined with their other status. The Court concluded that discrimination against a person because they are gay, lesbian or transgender means that you are discriminating against such a person based on that status, which is not protected, and their sex, which is. Thus, under the Bostock approach, because all of those who are victims of caste discrimination based on untouchability are from Asia, their caste is inextricably intertwined with their race. As a result, when Dalits are victims of intentional discrimination based on untouchabilty, the discriminator is motivated to discriminate against them because of their caste, which is not a protected trait, and their race, which is. Thus, intentional caste discrimination inevitably also involves race discrimination under both Title VII and Section 1981

DEVELOPMENT AND VALIDATION OF RP-HPLC METHOD FOR SIMULTANEOUS DETERMINATION OF DORZOLAMIDE AND TIMOLOL MALEATE IN PHARMACEUTICAL DOSAGE FORMS
A fast, sensitive and accurate reverse phase liquid chromatographic method was developed and validated for the simultaneous determination of Dorzolamide and Timolol maleate in ophthalmic preparations. Chromatographic separation was achieved on Inertsil ODS 3V C18 column (250 X 4.6 mm, 5 µm particle size) with mobile phase consisting of Acetonitrile and 1-Octane Sulphonic acid buffer (0.02M) pH adjusted to 3.5 ± 0.05 with o-phosphoric acid (36:64 V/V) at a flow rate of 1.0 mL/min. The analytes were detected at 254 nm and 295 nm for Dorzolamide and Timolol maleate respectively by PDA detector. Brimonidine was used as internal standard (IS). The retention time of Dorzolamide, Timolol maleate and Brimonidine were found to be at 6.020 ± 0.02, 8.254 ± 0.01 and 4.636 ± 0.01 mins respectively. The linearity of the method ranged between 4-720 and 1-180 µg/mL for Dorzolamide and Timolol maleate respectively with correlation coefficient 0.999 for both the drugs in binary mixture. The LOD was found to be 0.6951 µg/mL and 0.2489 µg/mL for Dorzolamide and Timolol maleate respectively and LOQ was found to be 2.3214 µg/mL and 0.8317 µg/mL for Dorzolamide and Timolol maleate respectively
Analysis of On Demand and Table Driven Routing Protocol for Fire Fighter Application
In an Ad hoc communication, the nodes are
randomly distributed in a region are moving arbitrarily. We
propose Analysis of On demand and Table driven routing
protocols for Fire Fighter Applications (AOTFF) in this paper.
The performance analysis on reactive protocols viz., AODV and
AOMDV as well as proactive protocol DSDV are compared with
Packet Delivery Fraction (PDF) and Simulation time. The model
of fire fighter is developed using routing protocol to cover
maximum area by knowing the path that is already been used . It
is observed that the performance of reactive protocols are better
than compared to proactive protocols.
Polychaete community structure of Vasishta Godavari estuary, east coast of India
The community structure of polychaete fauna from the Vasishta Godavari estuary was analyzed in this
study. The data presented in this paper were collected during 1976 - 78 and published in 1983, and now re-analysed using PRIMER 6.1, CANOCO 4.5. The polychaetes were collected from a 16 km stretch of the lower Vasishta Godavari estuary (16o18’N lat., 81o42’E long.) during flood, summer and recovery seasons at 6 permanent stations. Altogether 216 sediment samples were analysed and 73
polychaete taxa were identified. Polychaete diversity was higher (Shannon-Wiener H’: 1.94±0.28) in samples from recovery season relative to summer season (H’: 1.54±0.44) and flood season (H’: 1.44±0.024). Using multivariate statistical techniques two polychaete associations could be recognised from the Vasishta Godavari estuary, namely Heteromastus similis, Nephthys oligobranchia and Indonereis
gopalai assemblage Group 1 (samples from recovery and summer season) and Group 2 (samples from flood season). Group 2 did not reveal any particular species from flood season samples. Canonical correspondence analysis (CCA) showed that sand, salinity, clay and temperature have influenced the polychaete distribution. This study therefore provides key information on the biodiversity of polychaete communities of the Vasishta Godavari estuary
