An experiment entitled Varietal evaluation of carnation (Dianthus caryophyllus L.) under naturally ventilated polyhouse conditions of Prayagraj was conducted during December, 2018 – April, 2019 in Horticulture Research Field of Department of Horticulture, SHUATS, Prayagraj with respect to vegetative, qualitative, yield and economic parameters. The experiment was conducted in Randomized Block Design (RBD) with eight varieties replicated thrice. The varieties used were Krakatoa, Kino, Loris, Hillary, Madame Colette, Kitaro, Davinci and Cinderella. The results revealed that variety Davinci recorded maximum plant height (73.59 cm), number of shoots per plant (7.44), number of internodes (15.443), internodal length (6.153cm), stalk length (66.1cm), earliness (89 days), number of cut flower stalks per plant (7.55), number of cut flower stalks per square meter (181.2) and benefit cost ratio of 3.73. Variety Hillary (174.99) was recorded with maximum number of leaves, maximum flower length (5.4cm), and maximum flower diameter (6.27cm). Maximum bud length (3.17cm), maximum bud diameter (2.23cm), flower stalk girth (21.33) and maximum vase life (10.67) were recorded in the variety Cinderella. Minimum days taken to bud opening (FBI to paint brush stage) was recorded in the variety Kino (15.67). Thus, among the varieties studied, variety Davinci is more suitable for commercial cultivation under naturally ventilated polyhouse in Prayagraj agro climatic conditions.
Synthesis and characterization of bacterial cellulose/alginate blend membranes

Bacterial cellulose and alginate in an aqueous NaOH/urea solution were used as substrate materials for the fabrication of a novel blend membrane. The blend solution was cast onto a Teflon plate, coagulated in a 5 wt % CaCl2 aqueous solution, and then treated with a 1% HCl solution. Supercritical carbon dioxide drying was then applied for the formation of a nanoporous structure. The physical properties and morphology of the regenerated bacterial cellulose and blend membranes were characterized. The blend membrane with 80% bacterial cellulose/20 wt % alginate displayed a homogeneous structure and exhibited a better water adsorption capacity and water vapor transmission rate. However, the tensile strength and elongation at break of the film with a thickness of 0.09 mm slightly decreased to 3.38 MPa and 31.60%, respectively. The average pore size of the blend membrane was 10.60 A with a 19.50 m2/g surface area. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Les deplacements chimiques du 13C de trente-deux pyrazoles ont ete mesures dans le dimethylsulfoxyde hexadeuterie et l'hexamethylphosphorotriamide. Nous avons determine l'influence respective des differents substituants par regression multilineaire (substitutions par un methyle et un amino sur les carbones de l'heterocycle, et par un methyle, un n-butyle et un phenyle sur l'azote). Le probleme de la determination des constantes d'equilibre tautomere, a partir des resultats de la RMN du 13C est discute et illustre avec le cas des amino-3(5) pyrazoles. The 13C chemical shifts of 32 pyrazoles were measured in hexadeuterated dimethyl sulphoxide and in hexamethylphosphorotriamide. Substituent effects (methyl and amino groups on the pyrazolic carbons, and methyl, n-butyl and phenyl groups on the nitrogen) were calculated by multilinear regression analysis. The general problem of the 13C NMR study of annular tautomerism in azoles is discussed and illustrated by the 3(5)-aminopyrazole case.
Economics of finger millet (Eleusine Coracana (L) Gaertn) as influenced by land situations, various planting geometry and levels of fertilizer under lateritic soil of konkan region

The experiment “economics of finger millet (Eleusine coracana (L) Gaertn) as influenced by land situations, various planting geometry and levels of fertilizer under lateritic soil of Konkan region” was conducted at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.) during kharif season of 2017 and 2018. The field experiment was laid out in a split-split plot design. Main plot treatment consisted of three land situations viz., upland situation (LS1), midland situation (LS2) and gently sloppy (Varkas) land (LS3), the sub plot treatment consisted of five planting geometry viz.,15 cm x 10 cm (PG1), 20 cm x 10 cm (PG2), 25 cm x 10 cm (PG3), 30 cm x 10 cm (PG4) and 20 cm x 15 cm (PG5),while, sub-sub plot treatment comprised of five fertilizer levels viz., 80: 40: 0 NPK kg ha (RDF) without FYM (F1), 80: 40: 0 NPK kg ha (RDF) with FYM 5 t ha (F2), 80: 40: 40 NPK kg ha with FYM 5 t ha (F3), 100: 50: 50 NPK kg ha with FYM 5 t ha (F4) and 120: 60: 60 NPK kg ha with FYM 5 t ha (F5). Thus, there were 25 treatment combinations replicated three times. On the basis of investigation, it can be concluded that the finger millet crop should be grown during kharif season on upland situation (well drained) followed by gently sloppy land (Varkas) with 25 cm x 10 cm planting geometry along with application of fertilizer dose @ 100: 50: 50 NPK kg ha with FYM 5 t ha for obtaining maximum yield, quality, net returns and benefit cost ratio under south Konkan condition.
MEASUREMENT OF LEVELS OF ELECTROMAGNETIC ENERGY DENSITY EMITTED BY MOBILE PHONE TOWERS IN THE CITY OF MOSUL, IRAQ

This research deals with measuring the energy density levels of the mobile phone towers for the downlink of the GSM 900 and GSM 1800 frequency range signals for the Asiacell and Korek companies in the city of Mosul and comparing them with the national and international standards for radiation protection. This research used SRM-3006 to measure the energy density of electromagnetic radiation. Measurements were taken from mobile phone towers in the municipal humpback sector with the positioning of the towers using GPS. The results presented show that the radio frequency radiation levels of the constellation antennas do not exceed the permissible limits for different radio frequency signals. The average energy density (PD) in the frequency range of (900 MHZ) were 0.0872399 W/m2 for Asiacell and 0.0313094 W/m2 for Korek. Whereas, the average energy density (PD) in the frequency range of (MHZ 1800) were 0.16183177 W/m2 for Asiacell and 0.0607802 W/m2 for Korek. The highest total mean density was 0.17914139 W/m2, but many sites in this study are exposed in the two levels above 0.1 W/m2, which is the Russian border. The results of the energy density values obtained were higher when compared to other countries’ research this is due to some differences in measuring devices, measurement site standards, measurement equipment settings, survey methodology and urban planning. The use of GIS to draw maps of the distribution of radio towers and the level of radiation.
Removal of Cu(II), Fe(III), and Cr(III) from Aqueous Solution by Aniline Grafted Silica Gel

Abstract The aniline moiety was covalently grafted onto silica gel surface. The modified silica gel with aniline groups (SiAn) was used for removal of Cu(II), Fe(III), and Cr(III) ions from aqueous solution and industrial effluents using a batch adsorption procedure. The maximum adsorption of the transition metal ions took place at pH 4.5. The adsorption kinetics for all the adsorbates fitted better the pseudo second‐order kinetic model, obtaining the following adsorption rate constants (k2): 1.233 · 10−2, 1.902 · 10−2, and 8.320 · 10−3 g · mg−1 min−1 for Cr(III), Cu(II), and Fe(III), respectively. The adsorption of these transition metal ions were fitted to Langmuir, Freundlich, Sips, and Redlich‐Peterson isotherm models; however, the best isotherm model fitting which presented a lower difference of the q (amount adsorbed per gram of adsorbent) calculated by the model from the experimentally measured, was achieved by using the Sips model for all adsorbates chosen. The SiAn adsorbent was also employed for the removal of the transition metal ions Cr(III) (95%), Cu(II) (95%), and Fe(III) (94%) from industrial effluents, using the batch adsorption procedure.
Recovery of Valuable Tea Aroma Components by Pervaporation

The present work describes the possibility of using pervaporation to recover the tea aroma compounds from tea aroma condensate generated in the manufacturing of tea or instant tea, as well as directly from tea extract. Eight compounds that make a significant contribution to tea aroma, namely, trans-2-hexenal, linalool, cis-3-hexenol, 3-methylbutanal, 2-methylpropanal, benzyl alcohol, phenylacetaldehyde, and β-ionone, were studied in this work. Permeation studies for all of these compounds with poly(octyl methyl siloxane) (POMS) and poly(dimethylsiloxane) (PDMS) membranes in a batch-type vacuum pervaporation system were carried out, first, in their aqueous solutions (binary mixtures); second, in a model solution containing all of the above-mentioned compounds; and last, with an actual tea extract. In this work, mainly the effect of the feed concentration on the organic flux and separation factor was studied. The permeation studies with the mixture revealed that β-ionone, trans-2-hexenal, linalool, cis-3-hexenol, and 3-methylbutanal offered very good selectivity, whereas phenylacetaldehyde, 2-methylpropanal, and benzyl alcohol gave moderate selectivity. The results indicate that pervaporation is an attractive technology for the recovery of tea aroma compounds from tea aroma condensate as it (i) yields good separation and (ii) operates under mild conditions. However, it should be noted that, because the selectivity offered by pervaporation varies considerably from compound to compound, attempts to concentrate a solution of volatiles to a high degree can result in significant alteration in the profile of the aroma. Thus, the commercial utility of this approach will need to be ascertained on a case-by-case basis.
Filtration of Multi-Walled Carbon Nanotube Aerosol by Fibrous Filters

Filtration efficiency of multi-walled carbon nanotube (MWCNT) aerosol by fibrous filter was evaluated experimentally. Mono-mobility test aerosols with electrical mobility diameter of 100, 200, and 300 nm were generated by the atomization of MWCNT aqueous suspension followed by mobility classification with a differential mobility analyzer (DMA). By analyzing the shape of classified aerosol particles under a scanning electron microscope, it was found that the DMA-classified 300 nm particles were fibrous in shape and had uniform diameter of about 60 nm and length of 2.1 micrometer. On the other hand, 100 nm and 200 nm particles contained a fairly large amount of multiply charged fibrous particles with a larger diameter. These test aerosols were challenged to a medium performance fibrous filter at various filtration velocities. As a result, fibrous particles were captured by fibrous filter at a higher collection efficiency than the spherical particles with the same mobility. By analyzing the single fiber capturing efficiency, interception incorporating the rotation of fibrous particles is found to be the dominant capturing mechanism for the fibrous particles in the studied size range.
PHYSIOLOGICAL AND BIOCHEMICAL CHANGES DURING GROWTH AND DEVELOPMENT OF PERSIMMON FRUIT (DIOSPYROS KAKI L.) GROWN IN VIETNAM

Some biochemical changes according to the age of persimmon fruit grown in Vietnam were studied. The content of chlorophyll in persimmon peel reaches the highest value at 12 weeks old and decreases rapidly when the fruit is 22 weeks old, the content of carotenoids increase until the fruit is fully ripening. The content of vitamin C and reducing sugars increased continuously and reached the maximum value at 21 weeks old and then decreased slightly. Starch content gradually increases from the early stages and reaches its maximum at 15 weeks old, then decreases. Lipid content gradually increases from the early stages and reaches its maximum at 18 weeks old, then decreases. The content of protein decreased continuously from formation to fruit ripening. Based on the results of the research, we found that at week 21 the nutritional value of the fruit is the best, so persimmon fruit should be harvested at this time to ensure the nutritional value during storage.
Asymptomatic SARS-CoV-2 Carriers may not Generate Antibodies: A Case Report

Asymptomatic SARS-CoV-2 carriers are infectious to some extent and can potentially transmit coronavirus disease 2019 (COVID-19). RNA assay combining antibody detection significantly improved the sensitivity of pathogenic diagnosis for COVID-19. Here, we report an asymptomatic case of COVID-19 with positive RNA but consistently negative antibodies (IgM and IgG). This case indicates that not everyone can generate specific antibodies after infection with SARS-CoV-2. The absence of antibodies means that the asymptomatic carriers like our case have no specific resistance to the virus and their plasm may do no good in the treatment of the other COVID-19 patients. As RNA detectability of COVID-19 patients is not too high and will further decrease with the duration of disease, negative antibodies results may miss diagnosis. Therefore, repeated nucleic acid assay and antibody test should be carried out for suspected cases.
Wettability of montmorillonite clays in humic acid solutions

The effect of humic acid (HA) adsorption on the hydrophilicity of two different montmorillonite samples (Na-montmorillonite, NaMt, and a Na-fluorinated Na-montmorillonite, FNaMt, or ‘Rassoul’) was investigated. The changes in the wettability of clays were discussed in terms of the non-electrostatic free energy of interaction between the clay particles immersed in aqueous humic acid solutions (ΔG121), using the van Oss-Chaudhury-Good (vOCG) model. The surface free energy components (both non-polar or Lifshitz-van der Waals, and polar or acid-base) of clays were obtained from contact angle measurements, after adsorption of humic acid, at acid or basic pH, in 10−2 M NaCl solutions. It was found that: (1) at acid pH, a progressive decrease in the hydrophilic character of both clays was observed when the humic acid concentration was increased; (2) at basic pH, the hydrophilic character of both samples studied increased with HA concentration; (3) the effect of humic acid adsorption on the wettability of model edge surfaces of the laminar montmorillonite particles was estimated from a parallel study on silica and alumina surfaces, and only a slight decrease in the hydrophilicity was observed, whatever the pH of the liquid media. The ζ potentials of both clays in the absence and presence of humic acid were determined and the linkage between ζ potential and the electron-donor character of the materials is discussed.
EFFECT OF DIFFERENT CROP ESTABLISHMENT METHODS AND WEED MANAGEMENT PRACTICES ON WEEDS IN RICE

The field experiment was conducted to study the influence of different rice establishment methods and weed management practices on growth and yield of rice crop during kuruvai season of 2020-2021 at Experimental farm, Department of Agronomy, Annamalai University, Annamalai Nagar with five main plots as establishment methods and six weed management practices as subplots in split plot design on clay loam soil. The main treatments consisted of M1Direct dry seeded rice, M2Drum seeded rice, M3SRI transplanting, M4Machine transplanting, M5Conventional transplanting and sub treatments consisted of S1Unweeded control, S2Two hand weeding on 20 and 40 DAT/ DAS, S3Pre-emergence application of bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha-1 on 3 DAT/ 7 DAS + hand weeding on 40 DAT/DAS, S4Pre-emergence application of pretilachlor 6% + pyrazosulfuron-ethyl 0.15 % GR@ 10 kg ha-1 on 3 DAT/ 7 DAS + hand weeding on 40 DAT/ DAS, S5Pre-emergence application of herbicide bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha -1 on 3 DAT/ 7 DAS + Post-emergence application of bispyribac sodium 10% SC @ 200 ml ha-1 on 15 DAT/DAS and S6Pre-emergence application of pretilachlor 6% + pyrazosulfuron-ethyl 0.15 % GR@ 10 kg ha-1 on 3 DAT/ 7 DAS + Post-emergence application of bispyribac sodium 10% SC @ 200 ml ha-1 on 15 DAT/DAS. Among the different establishment methods compared as main treatments, SRI transplanting was found to be significantly superior than the other treatments. Among the different weed management practices compared as sub treatments two hand weeding on 20 and 40 DAT/DAS was found to be the best treatment and it was on par with pre-emergence application of bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha-1 on 3 DAT/ 7 DAS + Post-emergence application of bispyribac sodium 10% SC @ 200 ml ha-1 on 15 DAT/DAS. These sub treatments were significantly superior than the rest of the treatments in reducing the weed population, weed biomass and there by higher weed control efficiency. Hence, for SRI crop establishment method either with two hand weeding on 20 and 40 DAT/DAS or with pre-emergence application of bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha-1 on 3 DAT/ 7 DAS + Post-emergence application of bispyribac sodium 10% SC @ 200 ml ha-1 on 15 DAT/DAS could be a better option in managing the weeds in rice. The population of weeds as well as weed biomass was higher in direct dry seeded rice and unweeded control plots.
Guided Attentive Feature Fusion for Multispectral Pedestrian Detection

Multispectral image pairs can provide complementary visual information, making pedestrian detection systems more robust and reliable. To benefit from both RGB and thermal IR modalities, we introduce a novel attentive multispectral feature fusion approach. Under the guidance of the inter- and intra-modality attention modules, our deep learning architecture learns to dynamically weigh and fuse the multispectral features. Experiments on two public multi-spectral object detection datasets demonstrate that the proposed approach significantly improves the detection accuracy at a low computation cost.
THE HEPATOTOXIC EFFECTS OF MOBILE PHONE RADIATION (900 MHZ) ON MALE MICE AND THE HEPATOPROTECTIVE POTENTIALS OF ARCHITECTURAL SHAPES OF CAGES

Advances in technology, industry, economy and researches forced all people to continuous use of rapidly increased application of microwave (MW) radiation especially Wireless communication systems that is used daily in telecommunication, on line learning, medicine and even for animal farms management, these radiation uses always happen inside the buildings such as houses, schools, hospitals, offices, farms and public places leading to the threaten people’s and animals’ health especially vital organs and so this will reflect negatively on investment. Our study aimed to evaluate the possibility of new trends in hepatoprotection by potentiality of some famous historical architectural shapes as a physical protector against the harmful effects of the mobile phone radiation MPR, (900 MHz) for 8 weeks and to create healthy and high efficient architectural environments. Thirty-six (36) Swiss Albino male mice were randomly divided into 6 groups (n = 6), they housed in 6 cages with various shapes to assess the hepatoprotective effects of against MPR. Group I & II housed in a traditional cage, Group I served as a control which did not subjected to mobile phone but groups (II-VI) are exposed to mobile phone radiations. Our result revealed that these changes in architectural shapes (especially pyramid, bio-geometry and hexagonal shapes) can decreased the elevated hepatic enzymes either serum transaminases (ALT, AST) or alkaline phosphatase (ALP) in comparison to positive control groups and also restore the antioxidant capacity (total antioxidant (TAC), malondialdehyde (MDA) and nitric oxide (NO), reduced glutathione (GSH), catalase (CAT) plus retain the normal hepatic architecture in histopathology, it concluded that some specific architectural shapes may protect the liver from hazard of electromagnetic waves and this study can be useful for architects and advised to be used in the creation of healthy architecture buildings for either human or animal farms.
SCREENING OF FIVE PLANT SPECIES FOR MACRO/MICRO NUTRIENTS AND HEAVY METALS AT VARIOUS PHENOLOGICAL STAGES

This study presents the results of chemical analysis of five plant species. A total of 15 minerals were analyzed in these species at pre-reproductive and post-reproductive stages. These included 5 macronutrients i.e. P, K, Mg, Ca and S; 7 micronutrients i.e. Fe, Co, Ni, Cu, Zn, Mo, Mn and 3 trace elements i.e. Na, Si and Ba. Highest values were recorded for Ca while Co and Mo were below detection range in all samples. Based on mean values of all minerals the trend for all minerals in descending order for Aristida cyanantha was Ca > K > S > Mg > P > Fe > Si > Na > Zn > Cu: Ba > Mn, for Andrachne cordifolia Ca > K > Mg > P > S > Fe > Na > Mn > Zn >Ba > Cu > Si > Ni, for Quercus baloot it was found to be Ca > K > Mg > S > P > Fe > Mn > Ba > Si > Na > Zn > Cu > Ni, for Indigofera heterentha var. heterantha it stood as Ca > K > Mg > S > P > Fe > Si > Na > Ba > Mn > Zn > Cu > Ni and for Cotoneaster nummularia it was recorded as Ca > K > Mg > S > P > Fe > Si > Ba > Na > Mn > Zn > Cu > Ni. Factorial analysis confirmed that these minerals varied significantly in both phenological stages.
O Captain! My Captain! Leadership and Team Cohesion in the Union Army∗

We investigate the effect of leadership on team cohesion in a high-stakes setting, tracking military units during the American Civil War. In a matched commanding-officer to 100-men company panel dataset with frequent turnover in leadership, we find that commanding officers (captains) had a big impact on fighting units’ cohesion. Older, more courageous, and more experienced captains with working-class occupational backgrounds were most successful in maintaining units’ cohesion, particularly in the heat of major battles. Cohesion did not come at the cost of team production, as units with such captains also took more advanced positions in battle lines, and contributed more to winning battles. The data suggest that the Union Army recognized and promoted such officers. Higher-ranking officers determined tactics and strategy, but had less impact on the cohesion of fighting units.
Unversity of South Bohemia in České Budějovice Faculty of Science School of Doctoral Studies in Biological Sciences

Mesophyll conductance (gm) and stomatal conductance (gs) are two crucial components of the diffusive limitation of photosynthesis. Variation of gm in response to CO2 concentration was evaluated by using two independent methods based on measurements of variable electron transport rate (J) and instantaneous carbon isotope discrimination, respectively. Both methods of gm estimation showed a very similar shape of the gm/Ci relationship, with an initial increase at low substomatal CO2 concentrations (Ci), a peak at 180–200 mmol mol 21 Ci, and a subsequent decrease at higher Ci. A good correlation was observed between values of gm estimated from the two methods, except when Ci <200 mmol mol , suggesting that the initial increase of gm at low Ci was probably due to unreliable estimates over that range of Ci. Plants were also treated with abscisic acid (ABA), which induced a reduction in gs without significantly affecting the rate of photosynthesis, gm or the photosynthetic capacity. The present results confirm, using two independent methods, that gm is strongly sensitive to Ci, and that the relationship between gs and gm is not conservative, differing between control and ABA-treated plants.
