Published: May 2021

Background: Fluid management in neurosurgical patients is critical and important during the perioperative period. Electrical cardiometry (EC) is a new noninvasive technique for measuring cardiac output (COP). EC works based on the application of a high frequency transthoracic current and the analysis of variations of voltage in each heartbeat. The aim of this work is to compare the fluid management of intracranial surgeries using EC routine parameters.
Methods: This is a prospective randomized, double-blinded controlled study was carried out on 70 patients of both genders aged > 21 years old, ASA physical status II or III, GCS 15 scheduled for elective craniotomy. Patients were divided into two equal groups at random; group A: standard management, group B: EC guided management. The primary outcome was the duration of intensive care unit (ICU) stay.
Results: The ICU and hospital stay duration were significantly decreased in group B compared to group A. The mean total amount of infused volume of crystalloid solutions was significantly decreased in group B compared to group A. Hemodynamics, and number of patients received colloid, blood, vasopressor, and inotropes were insignificantly different between both groups. There was a significant increase in optic nerve sheath diameter in group A compared to group B at PACU and 24 h. Adverse events were comparable between both groups except encephalodema, which was significantly higher in group A.
Conclusions: EC is an effective tool in COP measurement and a novel guide for fluid therapy as EC guided fluid therapy group was significantly decreased in ICU and hospital stay duration and the total amount of crystalloid with fewer adverse events.

Published: May 2021

The present study evaluated the use of various phosphorus management practices with and without PSB on pearl millet and its residual effect on succeeding pulse crops like green gram, blackgram and chickpea. It was conducted at agricultural college farm, Bapatla during both kharif and rabi seasons of 2017-18 and 2018-19. The treatments consisted of T1: No Phosphorus, T2: 50% RDP T3: 75% RDP, T4: 100% RDP, T5: 50% RDP + seed inoculation with PSB, T6 :75% RDP + seed inoculation with PSB, T7 : 100% RDP + seed inoculation with PSB in RBD design with three replications in kharif pearl millet crop. The results indicated that, the treatment T7 (100% RDP + seed inoculation with PSB) recorded significantly the highest growth parameters like LAI, CGR, RGR and NAR at different phenological stages of crop growth period and yield of pearl millet (2996 kg ha-1 and 2876 kg ha-1 during 2017 and 2018 respectively) and it was at par with T4 (100% RDP). Similarly, the total fungi, bacteria and rhizobium counts were increased with increase in fertilizer level and PSB treated plots (T7, T6 and T5) when compared to un-inoculated PSB plots (T4, T3 and T2). The highest number of bacteria (46.2 and 49.2 cfu per gram soil), fungi (25.4 and 24.4 cfu per gram soil) and rhizobium (33.5 and 34.4cfu per gram soil) was found in the treatment T7 (100% RDP+ seed inoculation with PSB) during 2017-18 and 2018-19, respectively. Among the different kharif residual treatments, the highest pearl millet equivalent yield of rabi crops was recorded with residual effect of 100 % RDP + PSB (M7).

Published: May 2021

This study sought to identify factors that influence learning during training among small holder farmers on the new moisture conservation innovations (conservation farming) by Agricultural Technical and Extension Services (AGRITEX) and the objectives of the study was to identify the training methods used by AGRITEX officers in training Conservation agriculture and to find the effectiveness of the training methods in transferring knowledge
The study took the form of a case study. Six small holder farmers trained on the new moisture conservation innovations were researched on.
The study showed that AGRITEX to certain extent gave farmers some chance to participate during training especially in carrying out demonstrations, field days and during look and learn tours. The look and learn tours were appreciated most by many farmers as they were saying they can learn much by visiting other farmers. However, AGRITEX can further improve its training to improve learning among farmers through participatory course design which can help in the improvement of training for farmers to improve on practicing what they have trained.

Published: May 2021

AbstractA transition‐metal‐free method for the synthesis of arylselenides and aryltellurides has been established based on the oxidative cross‐coupling between diorganyl dichalcogenides and aryl boronic acids. With trichloroisocyanuric acid as an oxidant, the reaction proceeded smoothly to afford the desired products in 45–97% yields at ambient temperature. Three reaction reagents used in this method are stoichiometric and the oxidation by‐product isocyanuric acid can be easily isolated and recovered. Besides of arylboronic acids, aryl trifluoroborates and aryl trihydroxyborates salts are also able to perform this transformation.magnified image

AbstractExploring the effects of straw return (ST) and potassium fertilizer on soil structure, spring maize (Zea mays L.) root growth, K‐absorption efficiency and yield is essential for devising optimized straw return and potassium fertilizer management practices to increase grain yield for food security. In this study, two straw return levels used were straw return , no straw return and two potassium application levels used were 6K (90 kg/ha potassium application), no potassium (0K). Analyzed the effects of the above four treatments on soil structure, spring maize root indicators, K‐absorption efficiency and yield in three ecological regions in two years. The results showed that the effect of straw return on soil structure and root growth was better than that of applying potassium fertilizer. The effect of potassium fertilizer application on maize grain yield and K‐absorption efficiency was better than that of straw return. The impact of the interaction was better than straw return or the application potassium fertilizer alone. Straw return improved the effects of potassium fertilizer on soil bulk density, soil porosity, spring maize root length, root surface area, root volume, maize grain K‐absorption efficiency and yield by 3.99%–7.27%, 3.89%–7.40%, 1.35%–71.01%, 19.16%–42.45%, 10.49%–22.73%, 13.57%–19.67% and 4.43%–7.05%, respectively. Therefore, the interaction of straw return and potassium fertilizer was the best measure to maintain high and stable maize yield, increasing K‐absorption efficiency and improving the nutrient resource management of straw and potassium fertilizer, which was appropriate for spring maize planting.
Consumer preferences for foods with clean labels and new food technologies

Published: May 2021

AbstractFoods with “clean labels,” that is, foods with few ingredients, may mitigate the stigma from the lack of healthfulness in processed food products. However, with conventional technologies, clean labels are difficult to achieve. We conducted a survey, including choice experiment scenarios, in which half of the respondents were presented scenarios to purchase a shelf‐stable ready meal with a clean label/fewer ingredients, and the other half were presented scenarios including the clean label/fewer ingredients and a new technology that allows for processed foods to be produced with fewer ingredients. In general, respondents were willing to pay a price premium for the clean label and the new food technology used. However, such preferences were heterogeneous. In the version of the survey that did not include the type of technology, the classes were “clean label incredulous,” “moderate believers in clean labels,” and “strong believers in clean labels.” In the survey version including the type of technology, the classes were “clean label indifferent and technology takers,” “moderate believers in clean labels and technology indifferent,” and “strong believers in clean labels and technology indifferent.” Our findings underscore the importance of providing consumers with information about a new technology and the resulting benefits to reduce perceived risks and increase consumer acceptance.
Stereoselective Synthesis of Highly Substituted 1,3‐Dienes via “à la carte” Multifunctionalization of Borylated Dendralenes
Authors: Rivera‐Chao Eva , Fañanás‐Mastral Martín 
Published: May 2021

AbstractDespite the high relevance of 1,3‐dienes, stereoselective methods to access tetrasubstituted conjugated dienes are still scarce. We here report an efficient and modular approach that provides access to multifunctional tetrasubstituted 1,3‐dienes with excellent levels of regio‐ and stereoselectivity. This methodology is based on a tetracomponent reaction between a borylated dendralene, an organolithium reagent and two different electrophiles. Mechanistic studies reveal that this transformation proceeds through a regio‐ and stereoselective carbolithiation/electrophilic trapping of an in situ formed dendralenic boron‐ate complex, followed by a stereoretentive halodeborylation. The ease in which complex structural dienes can be accessed and their synthetic versatility highlight the importance and utility of this method.

AbstractCovalent organic frameworks (COFs) have emerged as an important class of organic semiconductors and photocatalysts for the hydrogen evolution reaction (HER)from water. To optimize their photocatalytic activity, typically the organic moieties constituting the frameworks are considered and the most suitable combinations of them are searched for. However, the effect of the covalent linkage between these moieties on the photocatalytic performance has rarely been studied. Herein, we demonstrate that donor‐acceptor (D‐A) type imine‐linked COFs can produce hydrogen with a rate as high as 20.7 mmol g−1 h−1 under visible light irradiation, upon protonation of their imine linkages. A significant red‐shift in light absorbance, largely improved charge separation efficiency, and an increase in hydrophilicity triggered by protonation of the Schiff‐base moieties in the imine‐linked COFs, are responsible for the improved photocatalytic performance.

AbstractWe report the single crystal XRD and MicroED structure, magnetic susceptibility, and EPR data of a series of CaMn3IVO4 and YMn3IVO4 complexes as structural and spectroscopic models of the cuboidal subunit of the oxygen‐evolving complex (OEC). The effect of changes in heterometal identity, cluster geometry, and bridging oxo protonation on the spin‐state structure was investigated. In contrast to previous computational models, we show that the spin ground state of CaMn3IVO4 complexes and variants with protonated oxo moieties need not be S=9/2. Desymmetrization of the pseudo‐C3‐symmetric Ca(Y)Mn3IVO4 core leads to a lower S=5/2 spin ground state. The magnitude of the magnetic exchange coupling is attenuated upon oxo protonation, and an S=3/2 spin ground state is observed in CaMn3IVO3(OH). Our studies complement the observation that the interconversion between the low‐spin and high‐spin forms of the S2 state is pH‐dependent, suggesting that the (de)protonation of bridging or terminal oxygen atoms in the OEC may be connected to spin‐state changes.

Published: May 2021

AbstractIsolation of CO2 from acetylene (C2H2) via CO2‐selective sorbents is an energy‐efficient technology for C2H2 purification, but a strategic challenge due to their similar physicochemical properties. There is still no specific methodology for constructing sorbents that preferentially trap CO2 over C2H2. We report an effective strategy to construct optimal pore chemistry in a CeIV‐based ultramicroporous metal–organic framework CeIV‐MIL‐140‐4F, based on charge‐transfer effects, for efficient inverse CO2/C2H2 separation. The ligand‐to‐metal cluster charge transfer is facilitated by CeIV with low‐lying unoccupied 4f orbitals and electron‐withdrawing F atoms functionalized tetrafluoroterephthalate, affording a perfect pore environment to match CO2. The exceptional CO2 uptake (151.7 cm3 cm−3) along with remarkable separation selectivities (above 40) set a new benchmark for inverse CO2/C2H2 separation, which is verified via simulated and experimental breakthrough experiments. The unique CO2 recognition mechanism is further unveiled by in situ powder X‐ray diffraction experiments, Fourier‐transform infrared spectroscopy measurements, and molecular calculations.

AbstractMolecular diagnosis is an essential means to detect pathogens. The portable nucleic acid detection chip has excellent prospects in places where medical resources are scarce, and it is also of research interest in the field of microfluidic chips. Here, the article developed a new type of microfluidic chip for nucleic acid detection where stretching acts as the driving force. The sample entered the chip by applying capillary force. The strain valve was opened under the action of tensile force, and the spring pump generated the power to drive the fluid to flow to the detection chamber in a specific direction. The detection of coronavirus disease 2019 (COVID‐19) was realized on the chip. The RT‐LAMP amplification system was adopted to observe the liquid color in the detection chamber to decide whether the sample tested positive or negative qualitatively.
Green banking disclosure, firm value and the moderating role of a contextual factor: Evidence from a distinctive regulatory setting

Published: May 2021

AbstractThe idea that green banking disclosure leads to increased firm value has been rightly considered as over‐simplistic. This paper builds on key prior insights by investigating whether combining green disclosure with other contextual factor, such as non‐performing loans, provides additional insight into the complex green disclosure–firm value relationship in a regulatory setting where green law has recently been enacted for the banking industry. We present an analysis of seven years of data sourced from listed banks in Bangladesh (2008–2014), with data analysed using multiple regression. Our findings indicate that, while green disclosure has a positive effect on the overall firm value of banks, this positive effect is negatively moderated by banks' non‐performing loans. This research contributes to the knowledge by showing that green disclosure alone is insufficient for creating market value for banks. Additional contextual matters need attention to understand the impact of green disclosure in contributing to increased market value for banks.

Published: May 2021

AbstractThis article explores the prospect of delivering counselling to people affected by dementia from the perspective of persons responsible for delivering an integrated dementia support service, emphasising an underpinning relational approach. Findings originate from interviews with an experienced counsellor, the counselling service co‐ordinator and people affected by dementia. Framework analysis was adopted to generate themes related to the study aims. Effective counselling delivery is reliant on the counsellor’s practice philosophy and appreciation of the lived experience of dementia from a person‐centred understanding. Participants discussed the benefits to offering a holistically understanding service, supportive of the needs of people affected by dementia, and how this can affect access or uptake of counselling. Findings demonstrated that counselling is a worthwhile and effective intervention to offer to people living with dementia and family caregivers. A number of recommendations for adjusting the scope of relationship‐based counselling to promote effective delivery have been made.

AbstractEnhancing the durability and performance of high‐energy‐density lithium–sulfur batteries (LSBs) is of paramount important for energy storage. We have fabricated a metal–organic framework‐derived (MOF) Co9S8/S (cobalt sulfide/sulfur) modified separator in LSBs which displays highest durability and excellent performance. The material successfully suppresses polysulfide shuttling, which is a determining factor in the deterioration of performance and lifetime of a battery. The Co9S8/S material is derived from a Co‐MOF. Its porosity and structural features make it an efficient material for capturing lithium polysulfides (LiPS), which is involved in chemical interactions with polarities within Co9S8/S. The kinetics of redox reactions involving LiPS are facilitated by the conductive properties of the material. A prolonged cycle life of 2000 charge–discharge cycles at a 1 C‐rate is observed when Co9S8/S is applied to the surface of a separator in the LSBs. An excellent discharge capacity of 879 mAh g−1 with the coulombic efficiency being maintained above 85 % throughout the course of 2000 charge–discharge cycles at a 1 C‐rate is achieved. Our strategy results in a material with unpresented high stability and durability of a MOF‐derived material which have fundamental importance in industrial and future commercialization of LSBs.

AbstractA combined experimental and theoretical study of the biphenyl (BP) crystal is presented. The X‐ray diffraction data collected at 100 K were subjected to Hirshfeld atom and multipole refinements of the electron density, ρ(r). A theoretical exploration of the potential energy surface (PES) of the crystal was also carried out. This investigation challenges the common assumption that the planar structure of BP in the phase I crystal is an average of two twisted configurations in a double‐well potential. The theoretical computations provide compelling evidence that this structure corresponds to a minimum on the PES hence to a stable molecular arrangement. Consistently, the experiment showed no evidence of positional or dynamic disorder. The intramolecular hydrogen‐hydrogen bonds detected are not repulsive. The topological analysis of the experimental and theoretical ρ(r) reveals that both the intra‐ and intermolecular H⋅⋅⋅H and the C−H⋅⋅⋅π contacts stabilize the BP crystal.

AbstractIn großtechnischen Prozessen bietet sich die Durchströmungswäsche zur Aufreinigung eines Filterkuchens an. Eine Vorentfeuchtung vor dem Waschschritt verhindert das unerwünschte Vermischen von Suspensions‐ und Waschflüssigkeit auf der Kuchenoberfläche. Der Einfluss dieser Vorentfeuchtung auf die Durchströmungswäsche wird mit einer Labornutsche untersucht. Der Vergleich von Entfeuchtungskinetik vor der Wäsche und Wiederbefeuchtungskinetik zu Beginn der Wäsche zeigt, dass die Wiederbefeuchtung innerhalb einer deutlich kürzeren Zeitskala abläuft. Die ursprüngliche Sättigung von S = 1 wird nicht mehr erreicht, sondern eine Gleichgewichtssättigung S < 1. Die Vorentfeuchtung bewirkt in keinem der drei Waschbereiche eine Verschlechterung, z. T. sogar leichte Besserstellungen, erhöht jedoch den Zeitbedarf.

BACKGROUNDThere are minimal data on long‐term surgical outcomes of patients who have undergone resection for Wilms tumor (WT) and neuroblastoma (NB).METHODSA retrospective review of patients in a long‐term survivor clinic between the years 1967 and 2016 in a pediatric tertiary care hospital (>5 years posttreatment) was performed.RESULTSEighty‐six survivors of WT and 86 survivors of NB who had ongoing follow‐up in the survivors' clinic were identified. The median age at diagnosis was 2.5 years (range, 0.4‐15.7 years) with a mean follow‐up of 22.3 years (±10.4 years) for WT. The median age at diagnosis for patients with NB was 0.9 years (range, 0.1‐8.6 months); mean follow‐up of 21.7 years (±7.9 years). Twelve patients with WT (14.0%) had at least 1 repeat laparotomy, 11.1% for bowel obstruction, at a median of 3 months from initial surgery. Twelve patients (14.0%) with NB required laparotomy and 8.1% for bowel obstruction, at a median of 12 years after initial surgery. The incidence of hypertension in patients with WT who had undergone nephrectomy was not outside of population norms. Patients who underwent thoracotomy for a NB have a higher incidence of scoliosis and Horner syndrome.CONCLUSIONSSmall bowel obstruction requiring laparotomy is significantly higher than the literature norms for both tumor patient populations and typically occurs in the early postoperative period for patients with WT and remotely in patients with NB. The long‐term surgical complications of patients who underwent resection for NB and WT clearly merit follow‐up and patient education within multidisciplinary long‐term survivorship clinics.
