Authors:   Agricultural Research Station (Swami Keshavanand Rajasthan Agricultural University), Sriganganagar- 335001 Rajasthan, SRIVASTAVA A.K.
Published: May 2022

The study was carried out during 2015-16 at district Sriganganagar under semi arid region of Rajasthan India with the aim to diagnose the soil fertility indicator by using DRIS norms to improve the kinnow orchards efficiency. A total 105 kinnow mandarin orchards were selected through the preliminary survey, all the selected orchards were divided equally 35 each in low, medium and high efficiency based on the yield. The soil and plant sample were collected from the orchards and subjected to analyze by using standard analysis protocols. Five tier DRIS norms were used for determining the soil properties limiting factor. The high efficient orchards had low pH (8.1) and CaCO3, (23.4 g kg-1) whereas, comparatively more organic carbon (2.7 g kg-1) , phosphorus (38.2 kg ha-1) and potassium (296.2 kg ha-1) than medium and low efficient orchards. The nitrogen, phosphorus and potassium contents were also high in high yield orchards and ultimately responsible for the better quality parameters viz. fruit weight (170.35 g), Juice (49.51 %), total soluble sugar (12.88 %) and low acidity (0.81 %) in high efficient orchards. The five tier DRIS norms suggested that < 8.8 pH, < 89.0 g kg-1 CaCO3, < 2.5 g kg-1 organic carbon and 14.2 kg ha-1 phosphorus were limiting soil fertility indicators in relation to fruit yield less than 14.5 t ha-1 for kinnow mandarin orchards of semi arid region of Rajasthan. It is evident from the DRIS norms in relation to soil properties and plant tissue concentration yield should be considered as low when it is less than 14.5 to 20.2 t ha-1. It is therefore imperative to manage these parameters for the better quality production and sustainability of kinnow orchards

Published: May 2022

A field experiment was conducted to study the Influence of varieties and sowing dates on growth and yield of kharif groundnut (Arachis hypogaea L.) at Anand Agricultue University, Anand, during kharif season of 2019 and 2020. The treatments consisted of three dates of sowing viz; first date of sowing - onset of monsoon, second date of sowing - 10 days after onset of monsoon and third date of sowing - 20 days after onset of monsoon with three varieties viz; GG 20, GJG 34 and TAG 37A. The experiment was replicated four times in randomized block design (factorial). Results showed that first date of sowing (onset of monsoon) proved significantly superior to other dates of sowing in respect of growth and yield characters. Significantly high pod yield (2176 kg ha-1 and 1862 kg ha-1) was recorded during 2019 and 2020 under first date of sowing, respectively which was statistically at par with second date of sowing (1937 kg ha-1 and 1592 kg ha-1) and significantly higher than the third date of sowing (1614 kg ha-1 and 1369 kg ha-1). In case of crop sown at onset of monsoon, rainfall, soil moisture and mean temperature favorable during crop growing period showed significantly higher pod yield. Among the varieties, significantly higher pod yield (2043 and 1701 kg ha-1) was recorded under GG 20 over other varieties GJG 34 and TAG 3A during both the years. Hence, variety GG 20 was the promising ones in terms of growth and yield in middle Gujarat agro climatic zone. On an average, onset of monsoon (early sowing) gave 13.4% higher pod yield than 10 days after onset of monsoon sowing. GG 20 was recorded 6.8 % higher pod yield as compared to the GJG 34.

A Pooled analysis was carried out to evaluate the general and specific combining ability effects in 9 diverse genotypes of bread wheat of diverse origin of cultivation, their 36 F1’s and 2 checks during Rabi 2020-21 at RCA, Udaipur in three different environments for grain yield and its component traits. Analysis of variance revealed the differences between parents and crosses for GCA and SCA, respectively due to GCA and SCA effects were significant for all the characters except days to 50 % flowering in E3 (GCA) on pooled basis. Similarly, mean squares due to GCA x E and SCA x E were significant for all characters revealed influence of environment on GCA and SCA, respectively. The variance due to GCA was higher than their respective SCA for all characters except spike length, awn length and harvest index indicated that additive type of gene action played role in the expression of all the traits. Among parents, DBW 173, HD 2967, GJW 463 and RAJ 4120 were exhibited significant GCA effects for grain yield and its component traits. Maximum significant positive GCA effects were exhibited by parent DBW 173 (1.80) over the environments. Among crosses, thirteen crosses recorded showed significant SCA effects for grain yield and its related traits. Cross, HD 2967 x DBW 173 was exhibited maximum positive significant SCA effects for grain yield and harvest index in the environments as well as on pooled basis. Cross, HD 2967 x DBW 173 depicted maximum SCA effects (4.00) followed by RAJ 3777 x RAJ 4120 (2.92) for grain yield over environments. Attempting cross combinations involving different parents with high GCA for desirable yield and other traits could be useful.

Para tal, a pesquisa foi delimitada à análise das diretrizes apresentadas na última edição da PNAN, por meio de leitura crítica do documento e seleção de informações focada em 2 propósitos: (1) levantar em que pontos a questão de gênero aparece de forma explícita; (2) levantar quais pontos podem afetar a vida das mulheres, ainda que de forma implícita. A partir desses levantamentos, se discutiu quais desdobramentos das diretrizes analisadas podem ter repercussões na vida das mulheres, com base na literatura científica sobre o tema. Concluímos que os principais pontos abordados no documento, que demandam maior atenção na perspectiva de gênero, são as carências nutricionais específicas, o aleitamento materno e as ações de prevenção e redução de prevalência de sobrepeso e obesidade. Ademais, a articulação com políticas de reconhecimento, redistribuição e representação, com foco em paridade participatória, devem estar articuladas com as políticas de alimentação e nutrição. Assim, este artigo se propõe a fornecer recomendações para a construção de uma agenda de alimentação que contemple as questões de gênero.
Fundamentos descoloniais dos Direitos Humanos
Authors: Sousa Marília Nascimento de
Published: May 2022

Este trabalho visa analisar a descolonização dos direitos humanos desde as necessidades humanas básicas no contexto de uma práxis plural latino-americana. Com isso, questiona se a abordagem descolonial expressa outro fundamento para estes direitos, diferente da concepção tradicional construída desde o discurso hegemônico. Tendo como marco teórico o pluralismo jurídico de teor comunitário-participativo, o presente trabalho problematiza os fundamentos tradicionais dos direitos humanos desde os processos liberatórios latino-americanos para uma base descolonial dos direitos humanos. O raciocínio empreendido dessa discussão é dedutivo e propõem-se a procurar prescrever os caminhos para uma fundamentação dos direitos humanos desde as necessidades radicais.

Durante vários séculos a mulher foi considerada como sendo de categoria inferior ao homem, com atributos predeterminados e papéis voltados ao cuidado. Contudo, a história verifica também o surgimento de movimento de mulheres, bem como, do movimento feminista, numa luta constante por reconhecimento e exercício de plenos direitos. Considerou-se o aspecto histórico para estudo de gênero como oportunidade para conferir a voz a um grupo específico de mulheres, realizou-se pesquisa de natureza qualitativa com objetivo de apreender a percepção de mulheres pesquisadoras sobre acesso aos direitos sociais, bem como as estratégias de enfrentamento ou mitigação das desigualdades entre gêneros. Durante a análise dos relatos de experiências dessas pesquisadoras sob o Artigo 5º da Constituição Federal de 1988, constatou-se significativas mudanças legislativas que passaram a observar questões relacionadas ao gênero, no planejamento de leis específicas. Todavia, a realidade das depoentes reafirma a necessidade da divisão equitativa de atribuições nas relações de trabalho e de cuidado da família. Estratégias de facilitação de acessos aos espaços de educação e lazer surgem da participação feminina.
In silico analysis of ferulic acid against therapeutic target proteins PPAR-?, SIRT1, FOXO1 and LXR-? for the treatment of hyperlipidemia
Authors: V. Ramamurthy , T.A.K Mumtaz Begum
Published: May 2022

Introduction and Aim: Hyperlipidemia is a worth-mentioning risk factor for a variety of rapidly spreading diseases such as cardio-vascular diseases, myocardial infarction, impaired glucose tolerance and metabolic syndrome. Peroxisome proliferator-activated receptor - gamma (PPAR-?), sirtuin 1 (SIRT1), forkhead box factor 1(FOXO1), and liver X receptor-alpha (LXR-?) are the important determinants of hyperlipidemia by regulating a plethora of transcriptional factors in metabolically active tissues such as adipose tissue, liver, and skeletal muscle. The present study aimed to evaluate the binding affinity of 4-hydroxy-3-methoxy cinnamic acid (ferulic acid) with therapeutic target proteins of hyperlipidemia using an in silico approach.
 
Materials and Methods: The in silico docking studies were performed between ferulic acid (PubChem CID: 445858) and PPAR-?, SIRT1, FOXO1, LXR-? with PDB ID of 3ADX – A chain, 4ZZI- A chain, 4LG0– A chain, and 3IPQ-A chain respectively by using Autodock 4.2 docking tool.
 
Results: The results revealed that ferulic acid exhibited maximum binding affinities with FOXO1 (-8.63) followed by SIRT1(-6.18), PPAR-? (-5.79), and LXR-? (-5.79) kcal/mol respectively. Ferulic acid interacted with FOXO1 with amino acids ASN 204, TYR 165 with a distance of 2.01 Å and 1.86 Å. Furthermore, the molecular interaction of ferulic acid with SIRT1 was at residues SER 441(2.20 Å), GLN 345(2.79 Å), and LXR-? was at amino acids ASP 444 (1.85 Å) and SER 418 (1.98 Å).

An investigation of the concept of homoeopathic imponderabilia using a Hahnemannian proving of focused pink light
Authors:   , Somaru Nevorndutt
Published: May 2022

Conduct a randomised, double blind, placebo controlled study in order to determine the sphere of action of the imponderable remedy Pink 30CH on healthy volunteers who recorded the signs and symptoms produced in order to determine the substances potential usefulness in a future clinical setting according to the Law of Similars. Determine and highlight the commonalities shared between the symptoms and themes produced by remedy Pink 30CH and the other selected imponderable remedies. In the homoeopathic drug proving of remedy Pink 30CH, provers were uninformed to both the nature of the substance as well as to the potency selected and used for proving purposes. Neither the provers nor the research investigator had any knowledge of who received the verum or the placebo until the end of the proving. Thirty (30) provers were selected after meeting the inclusion criteria of which thirty percent (30%) of the subjects received placebo in a randomised fashion. Verum and placebo were dispensed to the proving body in a set of six (6) powders which were taken sublingually three (3) times daily or until any proving symptoms were experienced. All provers were examined and made to record in their journals before, during and after the administration of the proving substance so as to serve as their own intra-individual controls. At the end of the proving period all journals were then recalled and all proving data recorded was then collated and edited into a repertory and materia medica format, which was then used to formulate a homoeopathic drug picture of the remedy that could be used in future clinical settings. The homoeopathic drug picture thus derived was then analysed with the aim of highlighting the important themes that were elicited during the proving. These symptoms and themes were then related and compared to seven (7) other imponderable remedies: Luna (Moonlight); Magnetis Polus Arcticus (North pole of the magnet); Magnetis Polus Australis (South pole of the magnet); Positronium (Anti-matter); Radium bromatum (Radium bromide); Sol (Sunlight) and X-ray, in order to expand the overall understanding of the commonalities shared by the imponderabilia as an entirety.

Abstract. Stable water isotopes are natural tracers in the hydrological cycle and have been applied in hydrology, atmospheric science, ecology, and paleoclimatology. However, the factors controlling the isotopic distribution, both at spatial and temporal scales, are debated in East Asia. For the first time, we made large scale (order 10000 km) continuous observations of near-surface vapor isotopes across China in both pre-monsoon and monsoon seasons, using a newly-designed vehicle-based vapor isotope monitoring system. For both seasons, the observed variations along the sampling route are mainly due to spatial variations, and marginally influenced by synoptic-scale variations. The data thus documents the spatial and seasonal variability of vapor isotopes. The spatial variations of vapor δ18O are mainly controlled by Rayleigh distillation during the pre-monsoon period, but significantly influenced by different moisture sources, continental recycling processes and convection during moisture transport during the monsoon period. The seasonal variation of vapor δ18O reflects the influence of the summer monsoon convective precipitation in southern China, and a dependence on temperature in the North. The spatial and seasonal variations in d-excess reflect the different moisture sources and the influence of continental recycling. The isotope-incorporated global spectral model (Iso-GSM) successfully captures the spatial variation of vapor δ18O during the pre-monsoon period owing to the large latitudinal contrast in humidity and temperature, the overall performance is weaker during the monsoon period. These results provides an overview of the spatial distribution and seasonal variability of water isotopic composition in East Asia and their controlling factors, and emphasize the need to interpret proxy records in the context of the regional system and moisture sources.

Abstract. Bottom-up accounting methods of carbon dioxide (CO2) emissions can provide high-resolution emissions estimates at a global scale; however, the necessary in situ observations to verify these emissions are limited in coverage. Space-based observations of CO2 in the Earth’s atmosphere expand this coverage to a near-global scale to inform carbon cycle science and record emission trends. This work applied an observing system simulation experiment (OSSE) to characterize the flux information contained in “Snapshot Area Map” (SAM) CO2 measurements from the Orbiting Carbon Observatory-3 (OCO- 3). Unlike previous space-based carbon-observing systems, OCO-3 SAMs provide spatially dense observations of CO2 over targeted urban areas at unprecedented coverage. A Bayesian inversion using synthetic data was applied to these SAMs to explore their effectiveness in optimizing estimates of fossil fuel CO2 (FFCO2) emissions from the Los Angeles Basin. Results demonstrated that errors in the locations of large point sources diminished the inversion’s ability to reduce errors at the sub-city-level. Furthermore, reductions in atmospheric transport error exacerbated these issues. Only after geolocation errors in large point source locations were removed and atmospheric transport error was reduced did individual SAM observations provide modest corrections to prior flux estimates. The aggregation of multiple SAMs proved to be effective in reducing systematic errors in manufacturing- and transportation-related estimates, demonstrating the need for similar measurements in future space-based missions.

Abstract. As explained in the latest Arctic Monitoring and Assessment Programme (AMAP)
report released in early 2021, the Arctic has warmed 3 times more
quickly than the planet as a whole, as well as faster than previously thought. The
Siberian Arctic is of great interest mainly because observations are sparse
or largely lacking. A research aerosol station has been developed on
Bely Island (Kara Sea) in western Siberia. Measurements of equivalent black
carbon (EBC) concentrations were carried out at the “Island Bely” station
continuously from August 2019 to November 2020. The source origin of the
measured EBC and the main contributing sources were assessed using
atmospheric transport modeling coupled with the most updated emission
inventories for anthropogenic and biomass burning sources of BC. The obtained climatology for BC during the period of measurements showed an
apparent seasonal variation with the highest concentrations between December
and April (60 ± 92 ng m−3) and the lowest between June and September
(18 ± 72 ng m−3), typical of the Arctic haze seasonality reported
elsewhere. When air masses arrived at the station through the biggest oil
and gas extraction regions of Kazakhstan, Volga-Ural, Komi, Nenets and
western Siberia, BC contribution from gas flaring dominated over domestic,
industrial and traffic sectors, ranging from 47 % to 68 %, with a maximum
contribution in January. When air was transported from Europe during the
cold season, emissions from transportation were more important. Accordingly,
shipping emissions increased due to the touristic cruise activities and the
ice retreat in summertime. Biomass burning (BB) played the biggest role
between April and October, contributing 81 % at maximum in July.
Long-range transport of BB aerosols appeared to induce large variability to
the absorption Ångström exponent (AAE) with values > 1.0 (excluding outliers). As regards the continental
contribution to surface BC at the Island Bely station, Russian emissions
dominated during the whole year, while European and Asian ones contributed
up to 20 % in the cold period. Quantification of several pollution
episodes showed an increasing trend in surface concentrations and frequency
during the cold period as the station is directly in the Siberian gateway
of the highest anthropogenic pollution sources to the Russian Arctic.

Abstract. The spatiotemporal variations in free-cellulose concentrations in atmospheric particles, as a proxy for plant debris, were investigated using an improved protocol with a high-performance liquid chromatography with pulsed amperometric detection (HPLC-PAD) method. Filter samples were taken from
nine sites of varying characteristics across France and Switzerland, with
sampling covering all seasons. Concentrations of cellulose, as well as
carbonaceous aerosol and other source-specific chemical tracers (e.g. elemental carbon, EC; levoglucosan; polyols; trace metals; and glucose),
were quantified. Annual mean free-cellulose concentrations within PM10 (particulate matter)
ranged from 29 ± 38 ng m−3 at Basel (urban site) to 284 ± 225 ng m−3 at Payerne (rural site). Concentrations were considerably higher during episodes, with spikes exceeding 1150 and 2200 ng m−3 at
Payerne and ANDRA-OPE (Agence nationale pour la gestion des déchets radioactifs Observatoire Pérenne de l'Environnement; rural site), respectively. A clear seasonality, with
highest cellulose concentrations during summer and autumn, was observed at
all rural and some urban sites. However, some urban locations exhibited a
weakened seasonality. Contributions of cellulose carbon to total organic
carbon are moderate on average (0.7 %–5.9 %) but much greater during “episodes”, reaching close to 20 % at Payerne. Cellulose concentrations correlated poorly between sites, even at ranges of about 10 km, indicating the localised nature of the sources of atmospheric plant debris. With regards to these sources, correlations between cellulose and typical biogenic chemical tracers (polyols and glucose) were moderate to strong (Rs = 0.28–0.78, p < 0.0001) across the nine sites. Seasonality was
strongest at sites with stronger biogenic correlations, suggesting the main
source of cellulose arises from biogenic origins. A second input to ambient
plant debris concentrations was suggested via resuspension of plant matter
at several urban sites, due to moderate cellulose correlations with mineral
dust tracers, Ca2+, and Ti metal (Rs = 0.28–0.45, p < 0.007). No
correlation was obtained with the biomass burning tracer (levoglucosan), an
indication that this is not a source of atmospheric cellulose. Finally, an
investigation into the interannual variability in atmospheric cellulose
across the Grenoble metropole was completed. It was shown that
concentrations and sources of ambient cellulose can vary considerably
between years. All together, these results deeply improve our knowledge on
the phenomenology of plant debris within ambient air.
High-resolution typhoon precipitation integrations using satellite infrared observations and multisource data

Published: May 2022

Abstract. Typhoon-related precipitation over land can result in severe
disasters such as floods and landslides, and satellites are a valuable tool
for estimating surface precipitation with high spatial-temporal resolutions.
Accordingly, this study develops a surface precipitation integration
framework to combine high-resolution observations from the radiometers of
two geostationary satellites, Fengyun-4A (F4) and Himawari-8 (H8), with
high-density rain-gauge observations or IMERG data and atmospheric
reanalysis data based on a random forest (RF) algorithm. The RF algorithm
integrates cloud and atmospheric features from radiometric observations and
reanalysis information, and the intensity and spatial distribution of
precipitation can be revealed by high-density rain-gauge or IMERG data. We
take three typhoons that made landfall in South China during 2018 as
examples. The F4-based and H8-based results using rain-gauge data as the
predictand both show excellent results, yielding correlation coefficients
(R) of ∼ 0.75 and probabilities of detection (POD) of
∼ 0.95. In contrast, when IMERG data are used as the
predictand, the corresponding R and POD drop to ∼ 0.5 and
0.93, respectively, due to the uncertainties related to IMERG retrievals. By carefully choosing the predictor, our RF algorithm successfully integrates the information from satellite observations, surface measurements and atmospheric reanalyses, resulting in precipitation estimates that are highly consistent with actual ground observations. Consequently, our proposed integration framework can reconstruct hourly surface precipitation estimates
at high spatial-temporal resolutions for historical typhoon studies.
