Published: September 2022

Method of application of irrigation to the crop plays one of the most crucial roles in plant growth, development and overall production of the crop. To study the effect of different types of irrigation methods on the yield of the pea (Pisum sativum L. var. PB-89) crop, a field experiment was conducted at the research farm of the Punjab Agricultural University, in the winter of 2016–17 and 2017–18. Five treatments, viz. drip irrigation on crop grown on level field (T1), drip irrigation on crop grown on ridges (T2), flood irrigation (T3) and furrow irrigation (T4) all at 100% ET level and rainfed irrigation (T5) were compared. Each method of irrigation application had a unique soil moisture pattern during the crop growing period. Soil microbial properties were also studied for different treatments and although there was non-significant difference in microbial population among treatments, there was significant difference of biologicalactivity of the microbes with respect to different irrigation treatments, as reflected by the recorded dehydrogenase activity of the soil. Population of microbes was maximum at flowering stage. Yield of the crop varied significantly with the method of irrigation used. Maximum yield was obtained under drip irrigation treatment

Published: September 2022

Después de la realización de los proyectos de investigación sobre los documentales de temática educativa producidos en España entre 1914-1939 y 1939-1970, se han constatado diferentes silencios y rumores que afectan tanto a la memoria como a la historia de la educación. Sabiendo que estos silencios y rumores se aplicaban sistemáticamente como política estatal y que afectaban tanto a la población vulnerable como a los intentos de cambio del sistema, es importante analizar porqué persisten y cómo la historia y la memoria de la educación se enfrenta a los mismos. Los silencios, al igual que las manipulaciones, son parte del ayer que condicionan el hoy. Ello no afecta solamente en el franquismo.En los distintos totalitarismos, así como en conflictos violentos se instaló el hábito de hacer acallar. También a través de la producción de informativos. Son distintas las respuestas que se han dado a la problemática de recuperar esta memoria educativa según los contextos políticos, culturales y sociales. Pero la incomodidad es parte inherente del indagar y difundir nuestro pasado. La memoria educativa las asume cuando se aproxima a una historia compleja que explica las experiencias educativas vividas y narradas. En el presente artículo se exponen aquellos elementos que nos han posibilitado explorar algunas de las premisasy de los potenciales de las memorias frágiles y las historias complejas como programa intencional de investigación alrededor de las fuentes audiovisualesproducidas como propaganda en un marco político totalitario. Las diferentes líneas de investigación que se produjeron en ocasión de los proyectos citados, pero no solamente exclusivos en los mismos,reforzaron la necesidad de ir avanzando en aquellas metodologías ecosistémicas que pudieran dar cabida a los recorridos derivados de los filamentos e interconexiones entre los elementos, ofreciendo con ello la posibilidad de narrar el silencio con la perspectiva de una historia social vinculada a la justicia y a la democracia.

Trichomonas vaginalis is transmitted sexually in humans affecting both male and female genital tracts. A cross sectional study to determine the prevalence of T. vaginalis infection among women attending Chukwuemeka Odumegwu Ojukwu University Teaching Hospital (COOUTH) Awka, Anambra State was conducted between November 2021 and January 2022. A total of 200 apparently healthy women between the ages of 19 – 42 years volunteered and participated in the study. The study participants included pregnant and non-pregnant women, married, singles and widows from various occupations. Their urine samples were collected, centrifuged and examined under the microscope within 2 hours of collection. Diagnosis was made by detection of T. vaginalis in the wet preparation of urine deposits. An overall prevalence of 3.0% was observed among the study participants. Prevalence of T. vaginalis was highest (5.9%) among the age group 25-30 years and no infection was observed among the age group 37-42 years. There was no significant difference in the prevalence of infection among the age groups (P>0.05). Highest prevalence of 3.2% was observed among pregnant women while the least (2.7%) was observed in non-pregnant women. There was no significant difference in the prevalence of infection between pregnant and non-pregnant groups (P>0.05). The highest prevalence (7.5%) was observed among the students while no infection was observed among the civil servants. There was also no significant difference in the prevalence of infection among the occupational groups (P>0.05). Married women recorded the highest prevalence (3.3%) and no infection was observed among the widows. There was no significant difference in the prevalence of infection in different marital status (P>0.05). Asymptomatic T. vaginalis infection is common in pregnant women. Routine screening for this infection during pregnancy is recommended in order to reduce potential adverse pregnancy outcomes.

Background: Conservation of voluntary nature reserves: physical characterization of flora of the biodiversity zones of the Zuénoula sugar complex (Central West, Côte d'Ivoire.
Objective: To protect and conserve biodiversity zones of the Zuénoula sugar complex for abundant and sustainable sugar production in Côte d'Ivoire.
Methods: A study of the perimeter boundaries and floristic structure of conservation areas was conducted in vegetation formations consisting of gallery forests, riparian forests and forest islands. The perimeter boundaries were determined by mapping the ecological sites with a GPS. The floristic list was established from surface and itinerant survey methods.
Results: The three ecological sites were delimited and mapped on an area of 139.55 ha. The flora, mostly from the Guinean-Congolese region, was rich in 106 species and dominated by Mesophanerophytes. It belonged mainly to the Caesalpiniaceae, Moraceae and Sterculiaceae families. The gallery forests FG3 and FG5 were the most stable. In addition, all environments were diverse and indicated a uniform distribution of species. Six vulnerable species including Afzeliaafricana and Mallotusoppositus, two Red List species including Miliciaexcelsa and Triplochitonscleroxylon and 41 species of Least Concern including Albiziaadianthifolia and Lanneanigritana were identified.
Conclusion: The ecological reserves of Zuénoula are rich and diversified in plant species. Their implementation allows for the reduction of industrial pollution.

Authors: Saad Badr Samar , Al Maria Ahmed Fekry , Hasby Hisham Adel , Shaheen Mohamed Abd El-fattah 
Published: September 2022

Background: Contact A-scan ultrasonic biometry is the most frequently utilized technique for determining axial length (AXL). Optical biometry is a technique that utilises partial coherence interferometry to determine ocular biometry parameters. The aim of this research was to compare the efficacy in estimating postoperative refraction by measuring intraocular lens (IOL) power by the optical biometry (IOL Master) and contact A-scan ultrasound plus Bausch & Lomb (B&L) keratometry after phacoemulsification surgery.
Methods: This prospective, comparative, interventional and randomized study involved 40 eyes with uneventful phacoemulsification surgery and in the bag IOL of adult patients with cataract. Subjects were allocated into 2 equal groups: group A: implanted the IOL power estimated by the automated method and group B: implanted the IOL power estimated by the manual method. All patients were subjected to complete ophthalmic examination, best-corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), snellen visual acuity, cycloplegics refraction and slit lamp examination.
Results: The mean predicted error of IOLM was -0.108 ± 0.462 (P= 0.311) in group A and was 0.053 ±1.092 (P= 0.830) in group B, and the Predicted error of A scan was -0.661 ± 0.686 (P= <0.001) in group A which is statistically significant and -0.340 ± 0.972 (P= <0.134) in group B. IOL power measured by IOLM in group A was significantly lower than IOL power measured by A-Scan (p =0.004). While the mean IOL power measured by IOLM in group B was significantly lower than IOL power measured by A-Scan (p =0.008).
Conclusions: The IOL Master accurately assesses the axial length of the lens and thus provides a significantly better prediction of IOL power and thus refractive outcome in cataract surgery than US biometry.
Unveiling the Aging Process of Organic Light‐Emitting Devices with Langevin and Hole Trap‐Assisted Recombination Exciplex Cohosts

Published: September 2022

AbstractExciplex‐forming cohosts have gained increasing interest due to their promising performances in organic light‐emitting diodes (OLEDs). Such electroluminescent stabilities of the exciplex cohosts depend on their charge‐carrier recombination. But intrinsic relationships between the recombination schemes and the electrical aging process of the exciplex cohosts are yet to be revealed. In this case, exciplex cohosts with two different recombination schemes, namely trap‐assisted recombination (TAR) and trimolecular Langevin recombination (LR), are compared. The LR‐dominated device achieves T90 lifetime (time to 90% of initial luminance) of ≈8600 h at luminance of 1000 cd m−2, which is >2.3‐time lifetime improvement compared with the hole TAR‐dominated ones. The corresponding degradation analyses confirms that hole carriers in hole TAR‐dominated cohosts are captured by phosphorescent guests, accelerating p‐type cohost deterioration through exciton‐polaron decomposition on susceptible aromatic amine groups, which reveals the electrical aging mechanism of exciplex cohost based devices. Moreover, exciton managements of the recombination region further suppress luminous decline and release undesirable exciton–exciton annihilations. The current findings offer an in situ technique to observe exciton and charge carrier aging processes with different recombination mechanisms and provide a general guidance for the development of highly efficient and long‐lifespan exciplex cohost based OLEDs.

AbstractPolycystic ovary syndrome (PCOS) is a common endocrine disease regulated by metabolic disorders, the effective intervention of which depends on diverse phenotypes (e.g., insulin resistance). Serum metabolic fingerprint (SMF) holds promise in characterizing the pathogenesis stress related to diseases; yet, PCOS diagnosis and phenotyping are time‐consuming and challenging due to the lack of an integrated metabolic tool. Here, a nanoparticle‐enhanced laser desorption/ionization mass spectrometry platform is introduced for one‐time serum metabolic fingerprinting and to identify the metabolic heterogeneity associated with obesity in PCOS patients. A decision tree based on the acquired SMFs is constructed, and real‐world simulations on independent internal and external cohorts are performed. The decision tree yields the area under the receiver operating characteristic curves (AUC) of 0.967 for PCOS diagnosis and AUC of 0.898 for phenotyping, respectively. The technical robustness of the “one‐stop shop” decision tree across laboratories is validated for clinical utility. The decision tree aims to improve PCOS management in comparison to clinical assessment, leading to a potential reduction in multiple blood tests and physician workload.

Published: September 2022

AbstractPlasmonic perovskite solar cells (PSCs) using core−shell type plasmonic particles are designed, which possess the plasmon resonance in the near‐infrared range. This can selectively strengthen the interaction of the perovskite layer with low‐energy photons. The mesoporous PSCs employing the plasmonic particles have delivered a 10%–15% enhancement of external quantum efficiency in the plasmonic resonance range. This surface‐plasmonic effect has been analyzed using complementary techniques, including selective wavelength excitation and time‐dependent photoluminescence. It is shown that the metal‐based core−shell‐type plasmonic structures in PSCs optimize the scattering and absorption of incident light and the dynamics of photogenerated carriers. Furthermore, both optical and electronic effects increase the power conversion efficiency of PSCs from 17.49% to 19.88%, paving a way toward controlling the thickness of the photoactive layer for advanced devices such as tandem solar cells.
Vanguard is a Glucose Deprivation‐Responsive Long Non‐Coding RNA Essential for Chromatin Remodeling‐Reliant DNA Repair
Authors: Zhang Ben , Thorne Rick Francis , Zhang Pengfei , Wu Mian , Liu Lianxin 
Published: September 2022

AbstractGlucose metabolism contributes to DNA damage response pathways by regulating chromatin remodeling, double‐strand break (DSB) repair, and redox homeostasis, although the underlying mechanisms are not fully established. Here, a previously uncharacterized long non‐coding RNA is revealed that is call Vanguard which acts to promote HMGB1‐dependent DNA repair in association with changes in global chromatin accessibility. Vanguard expression is maintained in cancer cells by SP1‐dependent transcription according to glucose availability and cellular adenosine triphosphate (ATP) levels. Vanguard promotes complex formation between HMGB1 and HDAC1, with the resulting deacetylation of HMGB1 serving to maintain its nuclear localization and DSB repair function. However, Vanguard downregulation under glucose limiting conditions promotes HMGB1 translocation from the nucleus, increasing DNA damage, and compromising cancer cell growth and viability. Moreover, Vanguard silencing increases the effectiveness of poly (ADP‐ribose) polymerase inhibitors against breast cancer cells with wild‐type breast cancer gene‐1 status, suggesting Vanguard as a potential therapeutic target.

AbstractWith the improvement of the airtightness of modern buildings, installing ventilation systems indoors is becoming increasingly important, which works for a long time continuously and needs to be monitored in real‐time. However, the complex wiring of monitoring sensors makes assembly and maintenance more difficult. This work reports a hybridized triboelectric‐electromagnetic nanogenerator (HNG) as a power supply of a self‐powered wireless monitoring system for ventilation systems. The HNG integrates an air inlet cover, a stator with coils and interdigitated copper electrodes, a rotor with magnets, fluorinated ethylene propylene films, and optimized built‐in wind blades. The HNG scavenges wind energy from a ventilation system and serves as a power supply for electric applications. Under the wind speed of 6.5 m s−1 in the ventilation system, the maximum stabilized voltage and maximum instantaneous current of the HNG are 177.5 V and 0.049 A, which can charge smartphones and light up a bulb. Furthermore, the HNG realizes the self‐powered wireless transmission of temperature and humidity sensing nodes. This work demonstrates an effective wind energy harvester, providing an innovative strategy for monitoring the condition of the ventilation system and broadening the thoughts of prospective energy harvesting.

Published: September 2022

AbstractTransition metal chalcogenides (TMCs) are widely used as energy storage materials, however, most studies have neglected the reconstruction process that occurs during the operation. Thus, the intrinsic energy storage mechanism of TMCs and the identification and modulation of the reconstruction process are not adequately investigated. Herein, a proactive modulation strategy for reconstruction kinetics under nonoperating conditions is proposed, and a potentiostatic reconstruction method is developed. The effects of three electrochemical techniques of potentiostatic, cyclic voltammetry, and galvanostatic on reconstruction products are also revealed. Notably, under potentiostatic reconstruction, the needle‐like nickel‐cobalt sulfide precursor is transformed into columnar, polycrystalline, defect‐rich nickel‐cobalt hydroxysulfate (NCHS‐E), and the process is analyzed in detail by in situ and ex situ characterization. NCHS‐E exhibits an excellent electrochemical performance with a specific capacity of 5040 mC cm−2 at 1 mA cm−2 and capacity retention of 67.1% at 50 mA cm−2. Kinetic analysis and theoretical calculations show that NCHS‐E has fast charge transfer ability and low deprotonation energy, indicating a favorable energy storage pathway. This work proves the important potential of reconstruction kinetic modulation to optimize the structure and properties of the products and provides new insights into the mechanism of reconstruction occurrence.

Published: September 2022

AbstractWith the advantages of adjustable structure and energy level, organic small molecules have been attracting much attention as hole transport materials (HTMs). Azulene was widely used in charge transfer materials for organic electronic devices. In this paper, two HTMs (Azu‐TPA and Azu‐OMeTPA) based on azulene core unit were synthesized by concise routes. Both Azu‐TPA and Azu‐OMeTPA demonstrate suitable molecular orbital energy levels as HTMs. Their hole mobility are over 10−4 cm2V−1S−1and conductivity are over 10−4 S cm−1, comparable with that of Spiro‐OMeTAD. Besides, they exhibit good hydrophobicity. Applied in PSCs, moderate power conversion efficiency (PCE) up to 15.41% was obtained. These results suggest the potential of azulene as a build block to develop HTMs with desirable electronic properties for perovskite solar cells (PSCs).

Published: September 2022

AbstractIn the arena of functional group‐oriented organic synthesis, nitrile or cyano functionality is of immense importance. The presence of nucleophilic N‐atom, π‐coordinating ability of the triple bond, and electrophilic C‐center imparts unique and interesting reactivities. Owing to the ability of the nitrile to transform into various other functional groups or intermediates, the chemistry is very rich and diverse. In particular, the involvement of nitrile in numerous organic reactions such as inter‐ or intramolecular alkyne insertion, [2+2+2] cycloaddition with alkynes, [3+2] cycloaddition with azides, [4+2] cycloaddition with dienes allow the synthesis of many important carbo‐ and heterocycles. Furthermore, the nitrile serves as a directing group in many C−H bond functionalization reactions to introduce diverse functionalities and participate as a radical acceptor in radical cascade strategies to obtain a large variety of functional molecules. This review mainly focuses on the reactivity and diverse synthetic application of the nitrile including C−H bond functionalization, alkyne insertion, cycloaddition, and thermal or photochemical cascade strategy. The objective of the current review aims at bringing out the striking collection of various nitrile‐triggered organic transformations.
