Field experiments were carried out during rabi seasons of 2015-16 and 2016-17 at the Research Farm, Punjab Agricultural University, Ludhiana. Wheat variety PBW 621 was sown on three dates (D1: 4th week of October, D2: 2nd week of November and D3: 4th week of November) with two irrigation levels (I1: IW/ CPE = 0.9, I2: At CRI, 5-6 weeks after 1st irrigation, 3-4/5-6 weeks after 2nd irrigation, 2/4 weeks after 3rd irrigation as per dates of sowing) and mulch application (M1: without mulch, M2: straw mulch @ 5 t ha-1). Earlier sown mulch applied crop with four post-sowing irrigations produced highest (5312.5 kg ha-1) and late sown without mulch application crop with irrigation @IW/CPE = 0.9 produced lowest grain yield (3900.5 kg ha-1). Simulation results depicted -1.1 to 16.8 per cent deviation in crop yield, -1.4 to -21.0 per cent in water use and 12.7 to 45.5 per cent in water productivity. Increase in temperature from 1oC to 3oC decreased wheat yield by 6.3 to 27.0 per cent under D1 and 3.3 to 17.6 per cent under D2, however, it increased from 8.1 to 16.2 per cent under D3, indicating D3 as most appropriate under future warming scenarios. Increase in CO2 concentration decreased water use and increased yield and water productivity.

The purpose of this study was to assess the evapotranspiration in field pea (Pisum sativum L.) in foothills valley areas of Manipur using the Hargreaves-Samani equation to predict the plant water demand. The crop coefficient (Kc) values ranged between 0.45 and 1.28 during the crop growth stages of field pea for the five crop seasons (2013-18). The average five-year effective rainfall was estimated to be 59.0 mm, with standard deviation (SD±) ranging between 4.4 to 35.1 mm. The average crop water requirement for field pea was estimated to be 221.0 mm and the average water demand for different crop growth stages of field pea was estimated to be 20.0 mm (initial stage), 52.0 mm (development stage), 100.0 mm (mid-season) and 49.0 mm (late season). Thus, the information generated may help in effective management of crop water requirements for sustainable crop production including field pea in the region.

The significance of the trends was tested by Mann-Kendall test for annual and seasonal rainfall. Among the 14 taluks, only Hassan taluk shows a significant positive trend in annual rainfall while eight taluks have shown non-significant positive trend and remaining five taluks have shown non-significant negative trend. The annual rainfall for the entire zone have shown non-significant positive trend. For the SWM season, Alur taluk shows a significant negative trend and eight taluks have shown non-significant positive trend. However, five taluks and whole zone showed a non-significant negative trend. Southwest monsoon and annual rainfall in Bhadravathi taluk was increased in 2007 (571.9 mm to 785.1 mm and 857.6 mm to 1090.9 mm, respectively) and in Shivamogga, the change in annual rainfall was decreased during 1983 (1497.5 mm to 944.0 mm) and 2011 (944.0 mm to 796.6 mm). The northeast monsoon rainfall was increased during 1992 (134.3 mm to 441.1 mm) and it was decreased during 1994 (441.1 mm to 162.0 mm) in Shikaripura taluk. Similarly, in Hunsur taluk, the SW Monsoon rainfall has increased (701.8 mm to 1010.2 mm) during 1991 and it was decreased during 2001 (1010.2 mm to 723.3 mm), in Periyapatna and Honnali taluk, Northeast monsoon rainfall has decreased during 2012 and 2011, respectively.

Dry chilli, which stands third in production from the spice industry, has influenced the Indian diet to a greater extent . The impact of climate change conditions on chilli crop could, in turn, impart the economy deeply. Hence, the future projection of dry chilli production will surely enrich knowledge about crop performance. Climate data from CCSM4 being downscaled from RegCM 4.4 was used in yield projection till the end of 21st century through DSSAT crop simulation for two major cultivars of chilli in Tamilnadu viz., TNAU chilli hybrid CO1 and K1 variety under rainfed conditions. TNAU chilli hybrid CO1 and K1 varieties have shown negative yield deviations for all the agroclimatic zones of Tamilnadu under variable time scales. However, southern zone was exclusive in exhibting positive yield by 7 percent and 5 percent, respectively, during the end of century.

Published: October 2021

AbstractThe high‐speed modulation of the nanoscale light sources is of fundamental interest in nanophotonics. Here, electrically driven light emission from a metal–insulator–semiconductor heterostructure consisting of graphene, hexagonal boron nitride (h‐BN), and monolayer tungsten disulfide (WS2) is demonstrated. Electroluminescence in these devices originates from radiative recombination of majority carriers (electrons) accumulated by electrostatic doping and hot minority carriers (holes) injected into monolayer WS2 from graphene through an ultrathin h‐BN tunnel barrier. The devices are electrically driven with a radio frequency signal and electrical modulation of the light emission at frequencies up to 1.5 GHz is demonstrated. The high‐speed WS2 tunnel diodes provide a promising path for on‐chip nanophotonics.

AbstractA low‐residue diet (LRD) is recommended as part of bowel preparation before a colonoscopy. However, the optimal duration of the LRD is unclear. A retrospective cross‐sectional study was therefore conducted at E‐Da Dachang Hospital. We compared bowel preparations using the Aronchick score and other quality metrics during two consecutive periods: May 2019 to December 2019 (3‐day LRD) and January 2020 to August 2020 (1‐day LRD). A total of 2823 patients were enrolled (1592 in the 3‐day LRD group and 1231 in the 1‐day LRD group). The most common bowel cleansing agent was sodium picosulfate and magnesium citrate (SPMC, 84.2%), followed by polyethylene glycol (PEG, 10.0%) and sodium phosphate (5.8%). Compared with patients in the 3‐day LRD group, patients in the 1‐day LRD group had higher SPMC use (88.1% vs 81.3%, P < .001) and supplemental laxative use (25.9% vs 19.3%, P < .001). The proportion of adequate bowel preparation (84.2% vs 85.1%, P = .563), cecal intubation rate, adenoma detection rate, and right‐side adenoma detection rate were not significantly different between 1‐day LRD and 3‐day LRD groups. More advanced adenomas (5.9% vs 3.4%, P = .002) and sessile serrated lesions (8.9% vs 6.3%, P = .014) were observed in the 1‐day LRD group. In addition, the types of laxatives (SPMC, sodium phosphate, and PEG) and the use of supplemental laxatives did not affect bowel preparation scores. In conclusion, a 1‐day LRD led to bowel preparation similar to that achieved through a 3‐day LRD regardless of the type of primary cleansing agent or the use of supplemental laxatives.

AbstractExposure science is fundamental to the field of occupational safety and health. The measurement of worker exposures to hazardous agents informs effective workplace risk mitigation strategies. The modern era of occupational exposure measurement began with the invention of the personal sampling device, which is still widely used today in the practice of occupational hygiene. Newer direct‐reading sensor devices are incorporating recent advances in transducers, nanomaterials, electronics miniaturization, portability, batteries with high‐power density, wireless communication, energy‐efficient microprocessing, and display technology to usher in a new era in exposure science. Commercial applications of new sensor technologies have led to a variety of health and lifestyle management devices for everyday life. These applications are also being investigated as tools to measure occupational and environmental exposures. As the next‐generation placeable, wearable, and implantable sensor technologies move from the research laboratory to the workplace, their role in the future of work will be of increasing importance to employers, workers, and occupational safety and health researchers and practitioners. This commentary discusses some of the benefits and challenges of placeable, wearable, and implantable sensor technologies in the future of work.

AbstractMenke–Hennekam syndrome‐1 (MKHK1) is a congenital disorder caused by the heterozygous variants in exon 30 or 31 of CREBBP (CREB binding protein) gene mapped on 16p13.3. It is characterized by psychomotor delay, variable impairment of intellectual disability (ID), feeding difficulty, autistic behavior, hearing impairment, short stature, microcephaly, and facial dysmorphisms. The CREBBP loss‐of‐function variants cause Rubinstein–Taybi syndrome‐1 (RSTS1). The function of CREBBP leading to MKHK1 has not been clarified so far, and the phenotype of MKHK1 significantly differs from that of RSTS1. We examined six patients with de novo pathogenic variants affecting the last exon of CREBBP, and they shared the clinical features of MKHK1. This study revealed that one frameshift and three nonsense variants of CREBBP cause MKHK1, and inferred that the nonsense variants of the last exon could further help in the elucidation of the etiology of MKHK1.

AbstractFür die Ermüdungsfestigkeit von Kopfbolzen zur Übertragung von Schubkräften in Verbundkonstruktionen stehen in Eurocode 4 normierte Wöhlerlinien zur Verfügung, die auf zahlreichen Schwingversuchen an Push‐out‐Körpern beruhen. Dagegen liegen in der Befestigungstechnik für an Ankerplatten geschweißte Kopfbolzen, bei denen neben Schub auch relevante Zugkräfte wirken, bisher nur wenige Kenntnisse vor, sodass deren Verwendung bei zyklischer Belastung derzeit nicht ausreichend geregelt ist. Im Rahmen eines aktuellen Forschungsvorhabens wurden experimentelle Untersuchungen an Einzelbefestigungen mit einbetonierten Kopfbolzen im Hinblick auf Stahlversagen durchgeführt. Die erzielten Versuchsergebnisse werden vorgestellt und daraus Ermüdungsfestigkeiten unter Zug‐ und Querbelastung abgeleitet. Auf Basis einer umfangreichen Versuchsdatenbank aus dem Verbundbau werden abschließend die Gemeinsamkeiten und Unterschiede im Vergleich zum Tragverhalten von Verbundmitteln diskutiert.
Protection of germline immortality by the soma via a secreted endoribonuclease

Published: October 2021

AbstractIn sexually reproducing organisms maintenance of germ stem cell immortality is fundamental for transmitting genetic material to future generations. While previous research has mainly considered intrinsic regulatory mechanisms in the germline, our recent study has found a direct contribution of somatic cells in preserving germline immortality via the somatically expressed endoribonuclease ENDU‐2 in Caenorhabditis elegans. We have identified ENDU‐2 as a secreted protein that can be taken up by the germline. Here, we discuss how ENDU‐2 might uncouple its RNA‐binding and RNA‐cleavage activities to control gene expression via either an endoribonuclease dependent or an independent way. We also speculate on a possible functional conservation of its mammalian homologs in mediating cell‐cell communication as well as its potential significance in understanding human pathogenesis such as cancer development.

AbstractObjectiveTo report on the development and preliminary findings of a community‐based cancer registry, including the community‐engaged approach to recruitment, participant profile, and distribution of cancer risk factors by race/ethnicity and geography.MethodsCommunity outreach and engagement best practices were used to recruit a diverse convenience sample of Virginia residents (≥18 years) that oversampled residents living in rural areas, defined as Rural‐Urban Continuum Codes (RUCC) 4–9 and African American (AA)/Black residents. Multiple survey administration methods included electronic (e‐survey) and in‐person survey by community‐based staff.ResultsAt the time of this analysis, 595 participants are enrolled; 73% are rural, 46% are AA/Black. AA/Black participants reported similar education but lower income (p < 0.01) and health literacy (p < 0.01), lower alcohol use (p < 0.001), fewer sedentary behaviors (p = 0.01), but greater BMI (p < 0.05) compared to White participants. Rural residents reported significantly lower household income (p < 0.001) and greater use of Medicaid (p = 0.01) compared to urban participants. Biennial mammography was reported by 82% of women aged 45–74 years old and colonoscopy by 77% of participants ≥50 years old. Tobacco use was reported by 17%; no differences in cancer screening or tobacco use were identified by geography or by race.Conclusion and relevanceCommunity engagement strategies successfully enrolled diverse residents within the cancer service area. AA/Black participants reported fewer cancer risk behaviors, similar educational attainment but lower income and health literacy compared to White respondents. Nuanced examinations of interactions among multilevel factors are needed to understand how individual, community, and institutional factors converge to maintain cancer disparities among AA/Black Virginians. Additional findings indicate a need for tobacco cessation, lung cancer screening, obesity treatment, and prevention initiatives.

AbstractArtificial biomimetic chromophore‐protein complexes inspired by natural visual pigments can feature color tunability across the full visible spectrum. However, control of excited state dynamics of the retinal chromophore, which is of paramount importance for technological applications, is lacking due to its complex and subtle photophysics/photochemistry. Here, ultrafast transient absorption spectroscopy and quantum mechanics/molecular mechanics simulations are combined for the study of highly tunable rhodopsin mimics, as compared to retinal chromophores in solution. Conical intersections and transient fluorescent intermediates are identified with atomistic resolution, providing unambiguous assignment of their ultrafast excited state absorption features. The results point out that the electrostatic environment of the chromophore, modified by protein point mutations, affects its excited state properties allowing control of its photophysics with same power of chemical modifications of the chromophore. The complex nature of such fine control is a fundamental knowledge for the design of bio‐mimetic opto‐electronic and photonic devices.

AbstractUpconversion luminescent (UCL) triggered photodynamic therapy (PDT) affords superior outcome for cancer treatment. However, conventional UCL materials which all work by a multiphoton absorption (MPA) process inevitably need extremely high power density far over the maximum permissible exposure (MPE) to laser. Here, a one‐photon absorption molecular upconversion sensitizer Cy5.5‐Br based on frequency upconversion luminescent (FUCL) is designed for PDT. The unusual super heavy atom effect (SHAE) in Cy5.5‐Br strongly enhances its spin‐orbit coupling (0.23 cm−1), triplet quantum yield (11.1 %) and triplet state lifetime (18.8 μs) while the potential hot‐band absorption of Cy5.5‐Br is well maintained. Importantly, Cy5.5‐Br can efficiently target the tumour site and kill cancer cells by destroying mitochondria under a biosafety MPE to 808 nm laser. The photostability and antitumor results are obviously superior to that of a Stokes process. This work provides a design criterion for FUCL dyes to realize effective PDT upon a biosafety optical density, possibly bringing more clinical benefits than conventional MPA materials.

AbstractIndenyl (Ind) rhodium N‐heterocyclic carbene (NHC) complexes [Rh(η5‐Ind)(NHC)(L)] were synthesised for 1,3‐bis(2,6‐diisopropylphenyl)‐4,5‐dihydroimidazol‐2‐ylidene (SIPr) with L=C2H4 (1), CO (2 a) and cyclooctene (COE; 3), for 1,3‐bis(2,4,6‐trimethylphenyl)‐4,5‐dihydroimidazol‐2‐ylidene (SIMes) with L=CO (2 b) and COE (4), and 1,3‐bis(2,4,6‐trimethylphenyl)imidazol‐2‐ylidene (IMes) with L=CO (2 c) and COE (5). Reaction of SIPr with [Rh(Cp*)(C2H4)2] did not give the desired SIPr complex, thus demonstrating the “indenyl effect” in the synthesis of 1. Oxidative addition of HSi(OEt)3 to 3 proceeded under mild conditions to give the Rh silyl hydride complex [Rh(Ind){Si(OEt)3}(H)(SIPr)] (6) with loss of COE. Tethered‐fluorenyl NHC rhodium complexes [Rh{(η5‐C13H8)C2H4N(C)C2HxNR}(L)] (x=4, R=Dipp, L=C2H4: 11; L=COE: 12; L=CO: 13; R=Mes, L=COE: 14; L=CO: 15; x=2, R=Me, L=COE: 16; L=CO: 17) were synthesised in low yields (5–31 %) in comparison to good yields for the monodentate complexes (49–79 %). Compounds 3 and 1, which contain labile alkene ligands, were successful catalysts for the catalytic borylation of benzene with B2pin2 (Bpin=pinacolboronate, 97 and 93 % PhBpin respectively with 5 mol % catalyst, 24 h, 80 °C), with SIPr giving a more active catalyst than SIMes or IMes. Fluorenyl‐tethered NHC complexes were much less active as borylation catalysts, and the carbonyl complexes were inactive. The borylation of toluene, biphenyl, anisole and diphenyl ether proceeded to give meta substitutions as the major product, with smaller amounts of para substitution and almost no ortho product. The borylation of octane and decane with B2pin2 at 120 and 140 °C, respectively, was monitored by 11B NMR spectroscopy, which showed high conversions into octyl and decylBpin over 4–7 days, thus demonstrating catalysed sp3 C−H borylation with new piano stool rhodium indenyl complexes. Irradiation of the monodentate complexes with 400 or 420 nm light confirmed the ready dissociation of C2H4 and COE ligands, whereas CO complexes were inert. Evidence for C−H bond activation in the alkyl groups of the NHC ligands was obtained.

AbstractThe excellent electrical conductivity of graphene is due to its highly‐conjugated structures. Manipulation of the electronic and mechanical properties of graphene can be achieved by controlling the destruction of its in‐sheet conjugation system. Herein, we report the preparation of CoCeSx−SA@BPMW@RGO through π‐π stacking interactions at the molecular level. In this study, sodium alginate was reacted with Co2+ and Ce3+, and the composite was loaded onto a graphene surface. The graphene sheets were prepared using a bi‐pyrene terminated molecular wire (BPMW) to avoid re‐stacking of the grapheme sheets, thereby forming nanoscale spaces between sheets. The angle between the BPMW coplanar pyrene group and the phenyl group was 33.2°, and the graphene layer is supported in an oblique direction. Finally, a three‐dimensional porous composite was obtained after annealing and vulcanization. The obtained CoCeSx−SA@BPMW@RGO exhibited excellent electrical conductivity and remarkable cycle stability. When the current density was 1 A g−1, its specific capacitance was as high as 1004 F g−1. BPMW modifies graphene through the synergistic effect of π‐π stacking interaction and special structure to obtain excellent electrochemical performance. Moreover, a solid‐state asymmetric supercapacitor device was fabricated based on the synthesized CoCeSx−SA@BPMW@RGO hybrid, which exhibited a power density of 979 W kg−1 at an energy density of 23.96 Wh kg−1.
