Abstract. Secondary organic aerosol (SOA) is formed through the oxidation of volatile organic compounds (VOC), which can be of both natural and anthropogenic origin. While the hydroxyl radical (OH) and ozone (O3) are the main atmospheric oxidants during the day, the nitrate radical (NO3) becomes more important during the night time. Yet, atmospheric nitrate chemistry has received less attention compared to OH and O3. The Nitrate Aerosol and Volatility Experiment (NArVE) aimed to study the NO3-induced SOA formation and evolution from three biogenic VOCs (BVOC), namely isoprene, α-pinene and β-caryophyllene. The volatility of aerosol particles was studied using isothermal evaporation chambers, temperature-dependent evaporation in a volatility tandem differential mobility analyzer (VTDMA), and thermal desorption in a filter inlet for gases and aerosols coupled to a chemical ionization mass spectrometer (FIGAERO-CIMS). Data from these three setups present a cohesive picture of the volatility of the SOA formed in the dark from the three biogenic precursors. Under our experimental conditions, the SOA formed from NO3 + α-pinene was generally more volatile than SOA from α-pinene ozonolysis, while the NO3 oxidation of isoprene produced similar, although slightly less volatile SOA than α-pinene under our experimental conditions. β-caryophyllene reactions with NO3 resulted in the least volatile species. Three different parametrizations for estimating the saturation vapor pressure of the oxidation products were tested for reproducing the observed evaporation in a kinetic modelling framework. Our results show that the SOA from nitrate oxidation of α-pinene or isoprene is dominated by low volatility organic compounds (LVOC) and semivolatile organic compounds (SVOC), while the corresponding SOA from β-caryophyllene consists primarily of extremely low volatility organic compounds (ELVOC) and LVOC. The parameterizations yielded variable results in terms of reproducing the observed evaporation, and generally the comparisons pointed to a need for re-evaluating the treatment of the nitrate group in such parameterizations. Strategies for improving the predictive power of the volatility parameterizations, particularly in relation to the contribution from the nitrate group, are discussed.
On the drivers of regime shifts in the Antarctic marginal seas

Published: October 2022

Abstract. Recent studies found evidence for a potential future tipping point when the density of Antarctic continental shelf waters, specifically in the southern Weddell Sea, allows the onshore flow of warm waters of open ocean origin. A cold-to-warm shift in the adjacent ice shelf cavities entails a multiplication of ice shelf basal melt rates and can possibly trigger instabilities in the ice sheet. From a suite of numerical experiments, aimed to force such a regime shift on the continental shelf, we identified the density balance between the shelf waters formed by sea ice production and the warmer water at the shelf break as the deciding element for a tipping into a warm state. In our experiments, this process is reversible but with evidence for hysteresis behaviour. Using HadCM3 20th-century output as atmospheric forcing, the resulting state of the Filchner-Ronne cavity depends on the initial state. In contrast, ERA Interim forcing pushes even a warm initialisation into a cold state, i.e., the system back to the cold side of the reversal threshold. However, it turns out that for forcing data perturbations of a realistic magnitude, a unique and universal recipe for triggering a regime shift in Antarctic marginal seas does not exist. Whether or not any given forcing or perturbation yields a density imbalance and thus allows for the inflow of warm water depends on the interplay between bottom topography, mean ocean state, sea ice processes, and atmospheric conditions.
How you teach changes who you reach: understanding the effect of teaching modality on student engagement, content interest, and learning in undergraduate hydrology
Authors: Georgakakos Christine , Knighton James
Published: October 2022

Abstract. There is a growing consensus that hydrology education should move towards student-led learning formats and simultaneously incorporate recent hydrologic technologies that reflect workforce expectations. There is a strong theoretical basis that supports an anticipation of improvements in learning outcomes from these shifts in teaching style; however, little empirical evidence has been collected to confirm this success. We measured the classroom impact of shifting between three teaching modalities: 1) instructor-led lectures, 2) student-led hydrologic modeling with the EPA Storm Water Management Model, and 3) student-led design evaluation studios of stormwater best management practices. Educational outcomes were measured with student surveys, direct observation of class activity, and student grades. In aggregate, the student population did not express a significant preference for one modality over another, yet individual students showed dramatic preferences for each modality. The total frequency of interactions between students and the instructor were similar across all three modalities; however, the frequency of student-initiated engagements (both total and unique engagements) significantly increased in both student-led modalities. Variations in student enthusiasm did not correlate with written assessment scores, possibly suggesting that alternating modalities improves interest in hydrologic science and increases perceptions of a positive classroom experience, without changing retention of hydrologic concepts. Our results suggest that multiple teaching modalities should be employed to engage the greatest number of students and generate enthusiasm for hydrology.
The first map of dominant crop sequences in the European Union over 2012–2018

Published: October 2022

Abstract. Crop diversification is considered as an important linchpin of the agroecological transition, whereas current dominant cropping systems are known to rely only on a few crops species – like cereals in the European Union (EU). To assess the benefits of crop diversification at large scale, an accurate description of current crop sequences is required as a baseline. However, such a description is lacking at the scale of the EU. Here, we developed the first map of dominant crop sequences in the EU for the period 2012–2018. We used the LUCAS dataset that provides temporally-incomplete land cover information from a stable grid of points covering the whole EU. Eight crop sequence types were identified using hierarchical clustering implemented on LUCAS data, and mapped over EU. We show, in France, that the relative importance of these eight crop sequence types (as estimated from LUCAS data) was highly consistent with those derived from an almost spatially-exhaustive temporally-complete national dataset (the French Land Parcel Identification System) for the same period, thus validating the method and the typology for this country. Land use (i.e. crop production area) derived from our map of dominant crop sequences was also highly consistent with land use reported by official statistics, both at national and EU levels, validating the approach at the EU-scale. This first map of dominant crop sequences in the EU should be useful for future studies dealing with agricultural issues that are sensitive to crop rotations. The map of dominant crop sequences types in the EU derived from our work is available at https://doi.org/10.5281/zenodo.7016986 (Ballot et al., 2022).
Southern Europe and Western Asia Marine Heat Waves (SEWA-MHWs): a dataset based on macro events

Published: October 2022

Abstract. Marine Heat Waves (MHWs) induce significant impacts on marine ecosystems. There is a growing need for knowledge about extreme climate events to better inform decision-makers on future climate-related risks. Here we present a unique observational dataset of MHWs macro events and their characteristics over the Southern Europe and Western Asian (SEWA) basins, named SEWA-MHWs dataset. The SEWA-MHWs dataset is derived from the European Space Agency (ESA) Climate Change Initiative (CCI) Sea Surface Temperature (SST) v2 dataset and it covers the 1981–2016 period. The methodological framework used to build the SEWA-MHWs dataset is the novelty of this work. Firstly, the MHWs detected in each grid point of the ESA CCI SST dataset are relative to a time-varying baseline climatology. Since intrinsic fluctuation and anthropogenic warming are redefining the mean climate, the baseline considers both the trend and time-varying seasonal cycle. Secondly, using a connected component analysis, MHWs connected in space and time are aggregated in order to obtain macro events. Basically, a macro event-based dataset is obtained from a pixel-based dataset without losing high resolution (i. e. pixel) information. SEWA-MHWs dataset can be used for many scientific applications. For example, we identified phases of the well-know MHW of summer 2003 and, taking advantage of statistical clustering methods, we identified the largest macro events in SEWA basins and we clustered them based on shared metrics and characteristics.
Assimilation of airborne gamma observations provides utility for snow estimation in forested environments

Published: October 2022

Abstract. An airborne gamma-ray remote sensing technique provides a strong potential to estimate reliable snow water equivalent (SWE) in forested environments where typical remote sensing techniques have large uncertainties. This study explores the utility of assimilating the temporally (up to four measurements during a winter period) and spatially sparse airborne gamma SWE observations into a land surface model to improve SWE estimates in forested areas in the northeastern U.S. Here, we demonstrate that the airborne gamma SWE observations add value to the SWE estimates from the Noah land surface model with multiple parameterization options (Noah-MP) via assimilation despite the limited number of the measurements. Improvements are witnessed during the snow accumulation period while reduced skills are seen during the snow melting period. The efficacy of the gamma data is greater for areas with lower vegetation cover fraction and topographic heterogeneity ranges, and it is still effective in reducing the SWE estimation errors for areas with higher topographic heterogeneity. The gamma SWE data assimilation (DA) also shows a potential of extending the impact of flight line-based measurements to adjacent areas without observations by employing a localization approach. The localized DA reduces the modeled SWE estimation errors for adjacent grid cells up to 32-km distances from the flight lines. The enhanced performance of the gamma SWE DA is evident when the results are compared to those from assimilating the existing satellite-based SWE retrievals from the Advanced Microwave Scanning Radiometer 2 (AMSR2) for the same locations and time periods. Although there is still room for improvement, particularly for the melting period, this study shows that the gamma SWE DA is a promising method to improve the SWE estimates in forested areas.
The temperature-dependent shear strength of ice-filled joints in rock mass considering the effect of joint roughness, opening and shear rates
Authors: Huang Shibing , Cai Haowei , Xin Zekun , Liu Gang
Published: October 2022

Abstract. Global warming causes many rockfall activities of the alpine mountains, especially when ice-filled joints in the rock mass become thawed. The warming and thawing of frozen soils and intact rocks was widely studied in the past several decades, however, the variation of shear strengths of ice-filled joints was not fully understood. Recently, some scholars studied the thawing process and strength loss of ice-filled joints at different temperatures, however, the influence of the joint roughness, opening and shear rate on ice-filled joints was not systematically investigated. In this study, a series of compression-shear experiments were conducted to investigate the shear strength of ice-filled rock joints by considering the effects of joint roughness, opening and shear rates. The shear strength quickly reduces with increasing temperature, especially above -1 ℃. In addition, the shear strength decreases with increasing joint openings but it increases with increasing joint roughness. When the joint opening is large enough, the effect of joint roughness disappears and the shear strength of ice-filled joints is equal to that of solid ice. Increasing shear rate will decrease the shear strength of ice-filled joints because the joint ice displays the brittle failure phenomenon at a high shear rate. The Mohr-coulomb criterion also can be used to characterize the relationship between the shear strength and the normal stress of ice-filled joints. However, a general strength model by considering the joint opening, normal stress and joint roughness should be proposed by a further study. This research can provide a better understanding of the warming degradation mechanism of ice-filled joints by considering the above important influencing factors.

Published: October 2022

Abstract. Rock glaciers are important hydrological reserves in arid and semi-arid zones, their activity status can indicate the existence of permafrost. We provided a more detailed rock glaciers inventory of Guokalariju (GKLRJ) to explore the development mechanism of rock glaciers in the transition belt between the semi-arid zone and humid zone, as well as estimate the water volume equivalent (WVEQ) and permafrost distribution probability. Results show that about 5053 rock glaciers were identified, covering a total area of 428.71 km2 at 4600–5300 m a.s.l. The main climate types in semi-arid zones and the extensive existence of ancient glaciers remain provided a basis for developing a large number of talus-derived rock glaciers. Rock glaciers are most developed in the alpine and moderate dry climate, and their altitude decreases with the increase of precipitation, and they depend on the original terrain strongly and are most concentrated on the west-facing aspect. The ratio of WVEQ in the intact rock glaciers of GKLRJ to glaciers is about 1:1.63, and the permafrost in the central and western regions has shown an apparent degradation trend in recent decades. These findings enrich the research on the evolution rules of rock glaciers in the semi-arid to humid alpine mountains in the Tibetan Plateau and further guide the development and management of local water resources and disaster prevention and reduction.

Az ősi fehérborkészítési technológia, a „kvevri” egyre nagyobb figyelmet kap a fogyasztók körében, nemcsak azért, mert egyedi és különleges, hanem azért is, mert a fenntarthatóság, a természetközeliség alapvető jellemzői ennek a borkészítési eljárásnak. Mindezt az is mutatja, hogy a hagyományos agyagedényes, ősi grúz eljárás 2013-ban felkerült az UNESCO emberiség szellemi kulturális örökségeinek listájára, valamint 2020-ban a Nemzetközi Szőlészeti és Borászati Hivatal (OIV) felvette a héjon erjesztett fehérbort a különleges borok kategóriájába. Ez a hullám Magyarországon is jelen van, hiszen a „natúr” bor és „narancsbor”, a 2021-es jogszabályban már megjelentek, mint „Egyéb, korlátozottan használható kifejezések”. A borkészítési eljárás lényege a héjon történő erjesztés és a mikrooxidáció, amelynek edényzete többféle lehet: amfóra vagy kvevri, kerámiatojás, spin-hordó, ennek függvényében változhat a borok kémiai összetétele, valamint az aromakomponensek prekurzor vegyületeinek képződése. A tanulmányban amfora és kerámiatojás edényzet használatából származó, a Tokaji borvidéken készített natúrborok vizsgálatára került sor.

Published: October 2022

Porphyromona gingivalis and Parvimonas micra are anaerobic microorganisms that are usually found in the normal oral microbiome. Bacteremia is rarely caused by P. gingivalis and there have been no reports of splenic abscess caused by P. micra. Treatments for P. micra include vancomycin, ceftriaxone, and metronidazole, while treatments for P. gingivalis include tetracyclines, macrolides, beta-lactam penicillins, and clindamycin. We report a case of a 76-year-old caucasian male with bacteremia caused by P. gingivalis and splenic abscess caused by P. micra. This patient presented with nonspecific symptoms: Fever, chills, body aches, and shortness of breath. He was treated with IV piperacillin-tazobactam that was later switched to ampicillin sodium/sulbactam sodium during his hospital course and underwent a splenectomy. He ultimately expired due to acute respiratory failure and cardiac arrest, secondary to post surgical complications. To our knowledge, this is the first case of P. micra and P. gingivalis coinfection
Treatment of retractile scar after a hypetrophic scar (HSs) in the hand with ADM (Dermacell)

Published: October 2022

Hypertrophic scars can occur anywhere on skin after a skin injury or wound. The reason is not fully understood, the result is the abnormal production of extra collagen and a decrease in elastin, which lead to these undesirable thick, raised stiff scars. Sometimes surgery is performed to cut out the scar or redirect the lines of tension on the scar. Usually, surgery is considered when other treatment options have failed. Dermacell is human acellular matrix (hADM) that is intended for supplemental support and covering for soft tissue repair. It acts as ECM. The expression and proliferation of extracellular matrix (ECM) molecules in the dermis, mediated by a range of growth factors and cytokines, is a fundamental element of wound repair.

In the present employment market, campus placement holds a great experience and gift for students as well as educational institutes. While, it helps to the student community in building a strong foundation for the professional career ahead without facing the real-world job struggle, peer-competition or family pressure, a good placement record gives a competitive edge to an institution / University in their educational market. Campus placements provide the students with a foot-in- the-door opportunity, enabling them to start off their career right after they have completed their course curriculum. Furthermore, they get to interact and engage with the industry professionals during the placement drives, which further help lay a foundation for their prospective career in the future as they familiarize with potential contacts from their chosen career field. Placements have gradually become an integral part of an institute’s offerings, which was not the scenario earlier. Nowadays, students pay special attention to placement records while selecting a college or university for the admission. And it is rightly so, if a student is paying huge amount of parents’ hard-earned money as fees to the institutes/Universities, he/she has the right to calculate the ROI (return on investment), which in this case is a lucrative job. This research paper clearly identifies various influencing factors of Covid19 on employment market, employment opportunities of young graduates during pandemic period and impact of Covid19 on employment market for fresher during first wave period of Covid19 in the study area.

Published: October 2022

Entrepreneurship learning based on successful entrepreneurial role models in educational institutions may promote education for sustainable development. Several theoretical perspectives, such as the human capital theory, entrepreneurial self-efficacy, and selfdetermination theory, argue that entrepreneurship education is positively correlated with students' entrepreneurial intentions because it provides them with adequate knowledge and skills and motivates them to pursue their entrepreneurial goals. Exposure to successful entrepreneurial models in entrepreneurship education programmes may be a significant factor in boosting student’s confidence in their ability to start a business and improving their attitudes toward entrepreneurship. The goal of this study is to identify characteristics that students believe are unique to a successful entrepreneur.

The Government of India has encouraged the shift to a less-cash society with its push for digital payments. With the launch of Digital India Programme, the government is taking a big step forward to transfer the country into a digitally empower knowledge economy. E-Commerce is buying and selling goods and services over the Internet. It is part of e-business structure that includes not only those transactions that centre on buying and selling goods and services to generate revenue, but also those transactions that support revenue generation. These activities include generating demand for goods and services offering sales support and customer service, or facilitating communications between business partners. Airline and travel tickets, banking services, books, clothing, computer hardware, software, and other electronics, flowers and gifts are some popular products and services that can be purchased online. An attempt has been made to analyze the problems and prospects of commerce on digitalisation in Dindigul district of Tamil Nādu. Primary data are collected randomly from 100 respondents of various commerce cashless transactions used by buyers and sellers in Dindigul district. The sample respondents opined that it is very easy to carry cards instead of carrying money and 66 percent of the peoples agreed it. The study found that majority of the respondents revealed that there are problems on no knowledge of using NET banking and on no knowledge of using POS in the study area. From this, it is clear that people are not having the knowledge about the cashless transactions. This is the ultimate goal of cashless society paradigm. Important issues which have been, or will be encountered in cashless society brought on in part by electronic cash. The government move aimed at curtailing the menace of black or counterfeit money which is largely used to fund criminals and terrorists as part of a parallel economy. Today, there is a sea change in the mindset of people with regard to be digital means of monetary dealings which are safe,

Published: October 2022

Silkworms (Tubifex spp.) obtained from contaminated habitats are used as live food by fish culture expertsin Riau Province. The main supply of these worms comes from the Sail River in the middle of PekanbaruCity and has received a lot of organic and inorganic waste such as heavy metals from domestic activitiesand the cityâs economy. Heavy metal content in this worm habitat is almost limited to be investigated toanswer the possibility of fish mortality by fish farmers in the future. This study aims to investigate thequality conditions, presence of heavy metals in water, sediment, and bioaccumulation in these silkwormsfrom three worm collection centers. Research data revealed that the presence of heavy metals in water withthe largest to the smallest concentration order is Zn> Pb> Fe> Cr> Cu> Cd and the highest concentration inZn ranges from 0.6364 Â± 0.14 to 1.6738 Â± 0.16 mgl-1 and the lowest at Cd between 0.007 Â± 0.003 to 0.0178 Â±0.005 mgl-1. This metal is also found in sediments with the largest to the smallest concentration of Zn> Fe>Cr> Cu> Pb> Cd with Zn being the highest ranging from 63.8896 Â± 1.23 to 121.1536 Â± 1.31 mg kg-1 and thelowest is Cd ranging 0.4642 Â± 0.14 to 0.9618 Â± 0.11 mg kg-1. The concentration of heavy metals in worms ishigher, especially essential heavy metals than in water and sediment with the order Zn> Fe> Cu> Cr> Pb>Cd and their respective concentration ranges are Zn 84.5556 Â± 1.50 to 92.8354 Â± 1.70 mg kg-1, Fe 41.0664 Â±2.78 to 61.3076 Â± 2.42 mg kg-1, Cu 6.8536 Â± 0.58 to 15.7204 Â± 0.46 mg kg-1, Cr 4.4846 Â± 0.39 to 8.9826 Â± 0.41mg kg -1, Cd 0.4148 Â± 0.12 to 1.9784 Â± 0.13 mg kg-1 and Cd 0.4148 Â± 0.12 to 1.9784 Â± 0.13 mg kg-1. The BAFvalue shows that the highest accumulation of heavy metals into the body of silkworms comes from wateras compared to sediment at all locations. This study shows that the worms and the natural habitat theycollect are contaminated with heavy metals, but are still suitable as live food in fish hatcheries.

Published: October 2022

Tsunami events are caused by a series of waves resulted from sudden changes in the water column, seismicactivities such as the eruption of underwater volcanoes,landslides on cliffs above or below the sea, andfalling asteroids. The Meteorology, Climatology, and eophysics Agency released a warning of a potentialearthquake in the southern part of Java Island, including the Malang Regency, with a magnitude of 8.7 onthe Richterâs scale. It means that a tsunami with amaximum inundation height of up to 22 meters coulddestroy Tamban Beach. The objectives of this study were1)to examine the spatial aspect of Tamban Beachand its relevance to the ecological aspect as well as thetime aspect related to the estimation,2) to formulatea strategy to save the community, and 3) to estimate the impact of the damage to cover and land use. Themethods used were a scoring technique and an overlay analysis using a Geographic Information System(GIS), with parameters including the distance to the coast and river from the sea, slope, elevation, land use,tsunami run-up prediction, and inundation model. The Partial Least Squares (PLS) method was used todetermine the relationship between the level of vulnerability of an area to the tsunami disaster with variousassessments and efforts to mitigate the disaster. The results showed that most of the coastal areas of TambanBeach had a moderate level of vulnerability, except for the residential areas that had a high level ofvulnerability. A tsunami mitigation strategy was significantly influenced by the areaâs level of vulnerabilityto a disaster and the assessment of disaster management efforts.

These are the pollens of certain trees (the oak which occupies the first position, Erica, Pine, Olivetree), the pollens of certain spontaneous herbaceous plants (of the family Compositae, Urticaceae (Parietal)),and pollen from certain grasses (of the family Poaceae (Fecal)). The results of the epidemiological surveyscarried out showed that the average allergy due to pollen was 198 in May for conjunctivitis and 100 in Aprilfor rhinitis and asthma. Overall, the maximum symptom frequency values recorded in March-April, Mayand August-November correspond to the maximum flowering of characteristic species. Seasonal variationsin symptoms reveal the probable role of pollens in their induction.

The present study aims to assess the relationship between water quality and macrophytes biomass of KongbaRiver, Manipur (Latitude 25.800 N to 25.680N and 93.030E to 94.780E longitude). Pearson correlation (r) testwas carried out to identify the association between water quality for sampling sites and the Macrophytes biomass. The analysis indicated that D.O is correlated negatively with all the macrophytes biomass. However,the values of nitrate and phosphate were positively correlated with the macrophytes biomass. Water qualitywith regard to temperature, pH, DO, Cl, Ca, Mg, Hardness, Alkalinity, NO3 andPO4 were analysed. Thepresent communication reflects seasonal variation of water quality in the river. Seasonal variation in biomassof macrophytes functional groups were estimated from the five study sites. Macrophytes biomass exhibitedthe trend as E>FF>Sub>RF in site (II, III, IV and V)whereas in site I macrophytes biomass was observed asE>Sub>RF>FF. The study reveals that the water quality ofthe Kongba River were found to be related tomacrophytes biomass either positively or negatively but the nutrients levels were within the normal rangefor macrophytes growth. Concentration of morenutrients in the water bodies can lead to eutrophicationand results in macrophyte bloom. Therefore, there is need to monitor and check the water quality at regularintervals and the growth of macrophytes to ensure the healthy development and maximum production ofbiomass.

Vitamin D is a fat-soluble vitamin that plays an important role in calcium absorption from the intestinecontributing to bone health and many other functions leading to health improvement. There are mainlytwo forms of Vitamin D, namely Vitamin D3 (Cholecalciferol) and Vitamin D2 (Ergocalciferol). Ergocalciferol(Vitamin D2) is a form of Vitamin D found in food, especially mushrooms. Mushrooms contain ergosterolin their cell membrane; exposure to sunlight/ultraviolet (UV) light causes a photochemical reaction thatisomerizes ergosterol to Vitamin D2. Mushrooms are extensively grown in North-East India from timeimmemorial by the ethnic people. In this study, Vitamin D2 from fruiting bodies of two Oyster Mushroomspecies, namely Pleurotus florida and Pleurotus cornucopiae, is quantified using a spectrophotometer at 264nm.This study aimed to determine the Vitamin D2 accumulation potential of both the species and to select thebest species with the highest Vitamin D2 accumulation potential. Fresh cultures of P. florida and P. cornucopiaewere maintained in CSIR-North East Institute of Science &Technology (CSIR-NEIST) Mushroom GermplasmUnit, Jorhat, Assam, India and cultivated in the cultivation unit. A total of 24 treatments were given to eachsample by exposing it to UV rays ranging from UV-A (365nm and 395nm) and UV-B (280nm and 310nm)for different time periods. It was observed that Vitamin D2 levels varied with different wavelengths used.In both the species, Vitamin D2 levels increased in the UV-B range than in the UV-A range. Moreover,between the two species under study, P. florida showed the highest Vitamin D2 accumulation potential at280nm when exposed for 120 minutes. The level of Vitamin D2 increased to an optimum level at 120 minutesof UV exposure and then declined upon the increase in the time period. The recommended daily allowanceof Vitamin D is 400-800 IU/day according to WHO. In this study, post-UV treatment, the Vitamin D2 levelsdrastically increased to a range of 1000-6000 IU approximately which is safe and can be used in thepreparation of Vitamin D supplements in future.

A field experiment was conducted at Rice Research Farm of Birsa Agricultural University, Ranchi, Jharkhand,during Kharif seasons of 2018 and 2019 to find out the effect of rice establishment methods and nutrientmanagement practices on growth, yield and economics of rice. The experiment was laid out in split plotdesign replicated thrice with rice variety Naveen as test crop. The treatments comprised of three differentrice establishment methods viz., normal transplanting, wet direct seeding using drum seeder and aerobicrice assigned to main plots and five nutrient management practices viz., RDF( 80:40:20 kg NPK/ha), 75%RDF + 25% N through FYM (60:30:15 kg NPK/ha + 20 kg N through FYM), RDF + 25% N through FYM(80:40:20 kg NPK/ha + 20 kg N through FYM) , LCC based nitrogen application and control (No fertilizer)assigned to sub plots. The soil was clay loam in texture and slightly acidic in reaction (6.2) having 4.3 g/kgorganic carbon, 230.00 kg/ha available soil nitrogen, 36.80 kg/ha available phosphorous, 161.20 kg/ha ofavailable potassium. Results revealed that wet direct seeding of rice using drum seeder recorded maximumgrain (42.19 q/ha) and straw yield (65.22 q/ha) which was comparable with transplanting method butwere significantly superior to aerobic rice. Among the nutrient management practices, application of RDF+ 25% N through FYM produced maximum grain (46.33 q/ha) and straw yield (71.53 q/ha) which wassignificantly better than rest of the treatments except LCC based N application. Among the differentestablishment methods, wet direct seeding of rice using drum seeder recorded maximum net return (58337`/ha) which was significantly higher than other establishment methods. The B:C ratio was also maximumwith wet direct seeding using drum seeder (2.00) which was statistically at par with aerobic rice (1.93).Among the nutrient management practices, LCC based N application gave the highest net return (64030 `/ha) and B:C ratio (2.28).

Published: October 2022

Bio-cycling of polyphenols in estuarine ecosystem have not been documented adequately among the floraand fauna thereof. Total phenolic contents, antioxidative potential and free-radical scavenging activityhave been analysed from three types of structural components (leaves of Acanthus illicifolius, and detritusloaded estuarine soil and a benthic fauna, Uca lactea annulipes), of the estuarine mangrove ecosystem of theNorth Eastern coastal belt of India. HPLC and MALDI-TOF Mass spectrometry analysis were performed toidentify and quantify the phenolic compounds. Results reveal that all the three samples contain Polyphenols that can be related through the process and pathways of eco-biological transformation. Though quantitativelyless, the presence of deprotonated polyphenols enriches the detritus laden soil. Interestingly, very fewparent ions of phenolic acids from leaf sample show up in the crab hemolymph. It contained new metabolitesconsisting of fragmented ions. This establishes the role of the fiddler crabs as agents participating in thebio-cycling of polyphenols and also depicts the interdependence of plants, animals, and soil for the exchangeof essential life supporting ingredients as an outcome of coevolutionary process.

Municipal Solid Waste management involves many stages like Generation, Source storage, Collection,Storage, Transportation, Processing and Disposal. Further, Municipal Solid Waste management can bedivided into two major components, i.e. Collection and Transportation Plan and the Disposal Plan. Inorder to account for all possible combinations, a Binary coding approach has been suggested. To focus onthe best process there is a need to develop a generic model. Different Models have been attempted with allpossible combinations of activities of Solid Waste Management. The process of elimination was carried outthrough the application of two/ two analytical matrix. The final model was narrowed down for the bestCollection and Transportation (CaT) plan and Disposal Plan by the process of elimination with the help oftwo/ two analytical matrix. The combination of CaT plan and disposal plan need to be subjected to theground realities for sustainability. The prevailing Government Rules and regulatory compliance checkscan further give a direction for the most feasible MSW Model typical models could be generated by takingdifferent possible combinations.
