Published: February 2023

Climate change have a considerable impact on crop water demand (ETc). The present study analyzed the spatio-temporal variation of the crop water requirement (ETc), crop water surplus deficit index (CWSDI), and the coupling degree of ETc and effective precipitation (Pe) for maize (Zea mays L.) crop grown in Haryana State of India using ArcMap 10.8 software. ETc was calculated using the Penman-Monteith method and crop coefficient (Kc) approach for 34 years (1985-2018) climatic data. Two statistical models, namely Mann–Kendall test and Sen’s slope estimator, were applied to understand the trend, while Pettitt's test was used to identify abrupt change points by using XLSTAT 2021 software.The result showed that for maize ETc ranged from 571 to 766 mm, CWSDI ranged from -29 to -74% and the degree of coupling of ETc and Pe ranged from 0.26 to 0.71 during 1985-2018. The decadal temporal variation of these indices indicated that ETc during 2007-2018 was relatively higher than it was from 1985-1995 and 1996-2006. The spatio-temporal values of CWSDI indicated that almost all the districts were under water deficit conditions for growing maize crop.Trend analysis showed significantly increasing trend of CWR for most of the districts except Jind, Mewat, Palwal, Panchkula, Rewari, Rohtak and Yamunanagar.The abrupt change point detection analysis of CWR indicates toward different change points, with maximum change points between the years 2004–2008.Such information will help to the farmers in the effective management of water for sustainable production under climate change in the near future.

Who is the Thief? Sara Lidman in Postcolonial Kenya
Sara Lidman wrote her second autobiographical African novel, Med fem diamanter, during a prolonged sojourn in Kenya (1962–1963) where she first lived in Kisumu, in the Nyanza province, near Lake Victoria, before moving to Njeri in Gikuyland. She was accompanied by Wambui Njonjo, the country's first school inspector. The Njonjo family was close to the Kenyattas. The question in the title of the essay, “Who is the Thief? Sara Lidman in Postcolonial Kenya?”, points at the post-colonial threshold dilemma of Kenyans being both perpatrators and victims of their own fate, freed from the colonial bonds but reintroduced to economic forms of western dependence. I examine two aspects of her allegorical chronicling of Kenya 1958–1963 and the symbolic killing of Thiongo, the homosexual, by his brother Wachira, the boy pining in the servitude of both Gikuyu patriarchy and the greed of western capitalism. The two aspects relate to the dynamics and ambivalence of power. In the first section I demonstrate how ‘stealing’ – both as an act of aggression and one of liberation – is manifested in cultural and linguistic artefacts, in the textures of women's kangas, in a Luo legend, in Christian mission. As a postcolonial writer Lidman is unique for her time in transliterating and contextualizing (not translating) Gikuyu and Kiswahili words, proverbs and stories. In the second section I examine how ‘love’ or the idealization of ‘love’, heterosexual and homosexual, deteriorates under the pressure of ‘thieving’. In Lidman's ideal world androgynity is central. Med fem diamanter is a Kenyan novel written in Swedish.

Published: February 2023

Background: Heart failure (HF) is a severe clinical syndrome caused by diversed etiologies. Classically left ventricle ejection fraction (LVEF) has been used as a diagnostic marker as well as to subdivide HF into 3 groups (HFpEF, HFmEF and HFrEF). However, the prognostic value of this index is not consistent in comparison to LV strain (GLS, GCS) which are not only able to detect heart failure at a very early stage (precede to EF change) but also to predict the primary outcome including HF readmission and death. The prognostic role of LV strain is independent and incremental to conventional echocardiographic parameters.
Methods: 67 patients diagnosed with chronic HFrEF (EF < 40%) in Vietnam National Heart Institute were consecutively enrolled in our study from January 2016 to September 2016. Clinical data were comprehensively evaluated and conventional echocardiographic parameters and two LV strain indices (GLS & GCS) were measured using speckle-tracking. All patients were followed-up for all-cause 12-month readmission or death after discharge. The relation between echocardiographic parameters and clinical events was analyzed in Cox proportional hazard model.
Results: GLS had a prognostic value of composite events after being adjusted with age, sex, heart rate, SBP, DBP, NT-ProBNP, renal clearance, LVEF and LVDd. GLS (cut-off = -7.5%; AUC = 0.738; p = 0.003) was a stronger predictor of composite event compared to LVEF (AUC= 0.66, p = 0.042) LVDd (AUC = 0.637; p = 0.025), LA diameter (AUC = 0.614, p = 0.03), NT-ProBNP (AUC = 0.663; p = 0.04) and hs-Troponin T (AUC = 0.592; p = 0.039).
Conclusion: Global longitudinal strain is and strong and independent predictor of readmission and death in patients with heart failure with reduced ejection fraction.

Authors: LEONARD AGU CHUKWUEMEKA 
Published: February 2023

This research focused on the separation and identification of bioactive components of the methanolic extracts of the buds of Syzygium aromaticum. A bioassay and phytochemical screening were performed on the various solvent fractions, and the most active fraction was subjected to spectroscopic analysis using infrared, mass spectroscopy, and nuclear magnetic resonance to determine the structure of the active compounds present. The methodology involved extracting the flower buds of Syzygium aromaticum using methanol, fractionating the plant extract using three solvents—n-hexane, ethylacetate, and methanol, and performing a bio Using the agar well diffusion method, the antibacterial properties of the three solvent fractions were ascertained. The analysis' findings revealed that each of the three solvent fractions had tannins, alkaloids, flavonoids, and reducing sugars; the only fraction to contain saponins was the ethylacetate fraction, and the only fraction to have glycosides. The results of the study further showed that the ethylacetate fraction had the strongest antimicrobial activity against the test organisms, inhibiting the growth of bacteria such as Escherichia coli, Salmonella typhi, Staphylococcus aureus, Bacillus subtilis, and Candida albicans at concentrations of 200 mg/mL. The structural elucidation of the active compounds responsible for the antimicrobial was done through spectroscopic analysis using infrared, nuclear magnetic resonance and mass spectroscopy. The antimicrobial activities of this plant highlighted the significance of the extracts in traditional drug preparations, according to the study's findings, which suggested that the antimicrobial properties of the flower buds of Syzygium aromaticum may be due to the synergetic or individual effects of the phytoconstituents found.

Published: February 2023

AbstractChiroptical materials capable of emitting circularly polarized luminescence (CPL) have been gaining intensive interest for their wide applications in fields of materials. In this work, a locally rotated molecular tiara Py5P5, in which five bulky pyrene units locate at one rim of Py5P5, and five small methoxy groups at the other, is designed. The planar chiral skeleton of Py5P5 can make five pyrene units being ordered in asymmetrical manner to arise the CPL emission from pyrene excimer, and the small methoxy groups rim in the other can ensure the interconversion between pR‐ and pS‐conformers of Py5P5 freely via local rotation. Thus, both left‐handed and right‐handed CPL may emit from pyrene units of Py5P5 stacked in the asymmetrical order with a high |glum| up to 1.28 × 10−3 under the induction of chiral amino acid derivatives. It is the first observation that both right‐handed and left‐handed CPL from pyrene excimer can be arisen from a single molecule by adding the simple chiral guests.
On the Rational Design of Mesoporous Silica Humidity Sensors
Authors: Füredi Máté , Alvarez‐Fernandez Alberto , Fornerod Maximiliano Jesus Jara , Fodor Bálint , Guldin Stefan 
Published: February 2023

AbstractMesoporous silica is commonly used as matrix for humidity sensors which operate on the principle of relative humidity (RH)‐dependent water uptake and read‐out by resistance (R) monitoring. Although numerous studies have been dedicated to improving sensitivity with conductive additives, the role of the pore architecture on the sensing behavior has not been systematically investigated so far. Herein, the effects of pore size and porosity on resistive sensing performance in the 0.5–85% RH range are showcased. Across various sensors, a clear correlation is identified between mesopore size and linear RH sensing range. Sensors with larger pores (≈15 nm) exhibit linear response in the 65 to 85% RH range with larger slope (ΔlogR/ΔRH) than sensors with smaller pores (<8 nm). Additionally, increasing porosity while retaining pore size, yields better overall sensor performance across the 15–85% RH range. In particular, a combination of pore size around 15 nm and porosity of 70% showcased a large resistance versus RH response (R0/R ≈ 10000) in the measured range, with quick response and recovery times of 3 and 9 seconds, respectively. These findings may serve as guidelines for developing broad spectrum high performance mesoporous sensors and for sensors specifically engineered to operate in specific RH ranges.
Biomimetic Remodeling of Microglial Riboflavin Metabolism Ameliorates Cognitive Impairment by Modulating Neuroinflammation

Published: February 2023

AbstractNeuroinflammation, for which microglia are the predominant contributors, is a significant risk factor for cognitive dysfunction. Riboflavin (also known as vitamin B2) ameliorates cognitive impairment via anti‐oxidative stress and anti‐inflammation properties; however, the underlying mechanisms linking riboflavin metabolism and microglial function in cognitive impairment remain unclear. Here, it is demonstrated that riboflavin kinase (RFK), a critical enzyme in riboflavin metabolism, is specifically expressed in microglia. An intermediate product of riboflavin, flavin mononucleotide (FMN), inhibited RFK expression via regulation of lysine‐specific methyltransferase 2B (KMT2B). FMN supplementation attenuated the pro‐inflammatory TNFR1/NF‐κB signaling pathway, and this effect is abolished by KMT2B overexpression. To improve the limited anti‐inflammatory efficiency of free FMN, a biomimetic microglial nanoparticle strategy (designated as MNPs@FMN) is established, which penetrated the blood brain barrier with enhanced microglial‐targeted delivery efficiency. Notably, MNPs@FMN ameliorated cognitive impairment and dysfunctional synaptic plasticity in a lipopolysaccharide‐induced inflammatory mouse model and in a 5xFAD mouse model of Alzheimer's disease. Taken together, biomimetic microglial delivery of FMN may serve as a potential therapeutic approach for inflammation‐dependent cognitive decline.
Efficient Narrowband Circularly Polarized Light Emitters Based on 1,4‐B,N‐embedded Rigid Donor–Acceptor Helicenes

Published: February 2023

AbstractNarrow‐band emission is essential for applicable circularly polarized luminescence (CPL) active materials in ultrahigh‐definition CP‐OLEDs. One of the most promising classes of CPL active molecules, helicenes, however, typically exhibit broad emission with a large Stokes shift. We present, herein, a design strategy capitalizing on intramolecular donor‐acceptor interactions between nitrogen and boron atoms to address this issue. 1,4‐B,N‐embedded configurationally stable single‐ and double helicenes were synthesized straightforwardly. Both helicenes show unprecedentedly narrow fluorescence and CPL bands (full width at half maximum between 17–28 nm, 0.07–0.13 eV) along with high fluorescence quantum yields (72–85 %). Quantum chemical calculations revealed that the relative localization of the natural transition orbitals, mainly on the rigid core of the molecule, and small values of root‐mean‐square displacements between S0 and S1 state geometries, contribute to the narrower emission.
ECNU‐13: A High‐Silica Zeolite with Three‐Dimensional and High‐Connectivity Multi‐Pore Structures for Selective Alkene Cracking

Published: February 2023

AbstractA high‐silica zeolite ECNU‐13 (Si/Al=23) with a new three‐dimensional (3D) pore system and a nanosized morphology has been developed, consisting of multitudes of 10‐membered ring (10‐R) medium pores and one set of 8‐R small pores. A phase‐discrimination strategy was proposed to synthesize ECNU‐13 by regulating the gel compositions and nucleation processes that were used for preparing 12‐R large‐pore germanosilicate IM‐20 with the known UWY topology. The crystallization was directed towards forming one set of single four‐ring (s4r) composite building units together with one set of double four‐ring (d4r) rather than two different types of d4r units in IM‐20. The electron crystallographic investigations elucidated that the ECNU‐13 structure was composed of two kinds of polymorphs as a result of distinct atomic positionings in s4r units. In catalytic cracking of 1‐butene, ECNU‐13 exhibited high propene selectivity (55.6 %) and propene to ethylene molar ratio (>4.7) superior to well‐studied conventional ZSM‐5 zeolite catalyst.
