Authors: Micheal F. , Mahmoud A. , Ishaya K. S. , Kpalo S. Y. 
Published: April 2023

Materials on construction site management are critical issue within the Nigerian subcontractors. Often, movement of materials to site from one point to the other point leads to more cost of goods. Hence, management of construction materials in building industries is a crucial aspect in project management. If these are not done properly it will lead to high costs in the construction phase. The present research seeks to assess the impact of Poor Materials Management (PMM) on waste materials in project in FCT, Abuja, Nigeria.
The research collects data through questionnaires from the field survey, interview and site observation. Descriptive statistics was used for the study, mean index score method of analysis were adopted. Result of the study indicates that considerable effect on material waste generation on any construction project site were observed as a result of poor materials management; effects on quality of building projects was observed to be moderate, and effects on profitability in the construction projects were observed to be both high and moderate.
The study concludes that effective management of materials in construction projects would decrease the amount of waste generation, raise the quality of construction work, and offer maximum profit to the contractors. The study recommendations that the government agencies should collaborate with construction industry in Nigeria to develop policies for adoption on waste management plan for the construction industry and guarantee that senior officers adopts the training and developing the younger staff on the latest techniques for site materials management and managerial tools.

The Dynamics of Economic Globalization and Income Inequality in Sub-Saharan African Countries: An Empirical Insight from Two Stage Least Square and Fixed Effect Approach
Authors: Elvis Sone Wang , Ewane Enongene Betrand 
Published: April 2023

Many empirical studies have examined the nexus between economic globalization and income inequality. However, findings are controversial, especially for developing countries, which require further investigation. This study, therefore, aims to examine the effect of economic globalization on income inequality using unbalance panel data in 19 Sub Saharan African countries (SSA) from 2000 – 2015. Due to endogeneity problem and cross sectional dependence, the model was analyzed using a two-stage least square (2SLS) regression and the fixed effect model with Driscoll-Kraay standard errors regression respectively. The findings reveal that FDI, Trade openness, and ICT development are positive and significantly link to income inequality while remittances have a negative and significant effect. This is an indication that economic globalization indicators (FDI, Trade openness, ICT) have failed to bring a fairer income distribution in these countries while remittances have contributed to income distribution. On basis of this conclusion, policymakers should pursue policies, which will enhance a balanced development and improvement in the socioeconomic welfare of the population by improving measures of income distribution.

AbstractThe use of the coordinated silver (I) complex based on solvate ionic liquid in epoxy resins is reported to enable unprecedented electrical and thermomechanical properties. The novel hybrid material is aligned at the molecular level using an electric field, demonstrating high electrical conductivity, excellent energy storage properties, and rapid curing behavior. The electric‐field treated epoxy resin system shows a maximum electric conductivity of 2.05 × 105 S m−1, 20 folds of the same untreated system, and 3 folds of the same treated system but with 5.0% silver nanoparticles. Furthermore, this system shows an ultrafast curing rate of around 500 s at a temperature of 42.0 °C and reveals excellent energy storage achieving an average capacitance of 27.5 F g−1 at a scan rate of 1.0 mV s−1. Quantum mechanics is applied and the synchrotron beamline is utilized to optimize and investigate the properties of the system, opening the door to the next generation of thermoset polymers with multifunctional properties.

Authors: Zhou Nan , Wang Dourong , Bao Yaqi , Zhu Ruixue , Yang Peihui , Song Lin 
Published: April 2023

AbstractLuminescent solar concentrators (LSCs) are capable of absorbing solar light over a large area, which subsequently converts light into luminescence at a red‐shifted wavelength and then redirects it to a smaller target to increase the per‐unit yield of photovoltaic devices. Among various LSC materials, perovskite nanocrystals (NCs) have attracted great attention due to their adjustable band gap, multi‐exciton effect, and good stability. In this review, a brief introduction of LSCs, including their advances and principles, is given, followed by a summary of perovskite‐NCs‐based LSCs. The selected examples for component optimization of inorganic perovskite NCs are outlined after an introduction to the structure and properties of perovskite NCs. The absorption and/or emission peaks of all‐inorganic and inorganic–organic hybrid perovskite NCs can be efficiently regulated, which not only increases the Stokes shift but also improves the stability. Excellent performance and operability show a bright application prospect of perovskite NCs in the field of LSC applications.

AbstractIntroductionAngiotensin‐converting enzyme (ACE) has been implicated in the metabolism of amyloid beta; however, the causal effect of ACE inhibition on risk of Alzheimer's disease (AD) dementia and other common dementias is largely unknown.MethodsWe examined the causal association of genetically proxied ACE inhibition with four types of dementias using a two‐sample Mendelian randomization (MR) approach.ResultsGenetically proxied ACE inhibition was associated with increased risk of AD dementia (odds ratio per one standard deviation reduction in serum ACE [95% confidence interval]; 1.07 [1.04–1.10], P = 5 × 10−07) and frontotemporal dementia (1.16 [1.04–1.29], P = 0.01) but not with Lewy body dementia or vascular dementia (P > 0.05). These findings were independently replicated and remained consistent in sensitivity analyses.DiscussionThis comprehensive MR study provided genetic evidence for an association between ACE inhibition and the risk for AD and frontotemporal dementias. These results should encourage further studies of the neurocognitive effects of ACE inhibition.HIGHLIGHTS
This study evaluated genetically proxied angiotensin‐converting enzyme (ACE) inhibition association with dementias.
The results suggest an association between ACE inhibition and Alzheimer's disease.
The results suggest an association between ACE inhibition and frontotemporal dementia.
Those associations can be interpreted as potentially causal.

Published: April 2023

AbstractA custom design multi‐flying jet plasma torches (MFJPT) reactor was tested for plasmolysis of water vapor and mixtures of water vapor‐carbon dioxide in a series of experimental investigations at various reactor operational parameters. Experimentation plans were applied within the range of induced power (100–300 watts) and various vapor/gas throughputs. The produced gases were analyzed through online gas chromatography. The results of water vapor plasmolysis in two schemes demonstrated the production of 1337 ppm of hydrogen from water vapor/argon and 1665 ppm from applying a water vapor/argon/CO2 combination. Valuable hydrocarbon gases (e.g., Ethane, Ethylene/Acetylene) were generated and detected at higher conversions upon introducing H2O vapor, argon, and CO2 mixtures. The experimental data were trained through machine learning and a Gaussian Process Regression (GPR) model has fitted the data quite well. Ultimately, optimization study outcomes are presented through a color heat‐map for system scaling‐up purposes.

AbstractBackgroundUrologic guidelines universally recommend increasing fluid intake for kidney stone prevention. Increased voided volume is thought to help reduce stone recurrence and severity, but supporting evidence is limited.Patients and MethodsNephrolithiasis outcomes and 24‐h urine data for patients from the Registry for Stones of the Kidney and Ureter (ReSKU), a registry of nephrolithiasis patients collected between 2015 and 2020, were retrospectively analysed. Outcome was stone events, either an office visit where a patient reports symptomatic passage of stones or surgery for stone removal.ResultsWe identified 450 stone patients with 24‐h urine and kidney stone outcome data. There was no significant difference in 24‐h voided volume between patients with one stone event and patients with two or more stone events. On multivariable logistic regression, after controlling for age, gender, BMI, and 24‐h sodium and creatinine per kilogram, no significant associations were found between voided volume and stone events. There was a statistically significant negative correlation noted between voided volume and stone events in calcium oxalate dihydrate stone formers (Spearman R = −0.42, p = 0.04), but not others.ConclusionsTwenty‐four‐hour voided volume was not associated with stone events in a large institutional cohort, and subset analysis reveals that some stone formers may benefit more from increased voided volume than others; identifying such patients represents a novel precision medicine opportunity.

Published: April 2023

AbstractBioluminescent bacteria in the form of a cell suspension for on‐site hazard analysis are not suitable as in vivo luminescence in free cells fluctuates and may lead to erroneous results. Furthermore, the culture broth cannot be stored for long durations to continue sensing analytes as the luminescence ceases over time. Factors that affect luminescence response include growth dynamism, and ambient environmental conditions. The present study investigated the effect of storage conditions such as temperature (25 ± 2°C, room temperature; 4°C; and −20°C) and ambient aqueous environment (M1: sucrose, 1.02 M; M2, bioluminescent media [tryptone, 10 g L−1; NaCl, 28.5 g L−1; MgCl2.7H2O, 4.5 g L−1; CaCl2, 0.5 g L−1; KCl 0.5 g L−1; yeast extract, 1 g L−1; H2O, 1 L]; M3, bioluminescent media and 95% glycerol, 1:1 ratio) on the luminescence emission from the calcium alginate‐immobilized Photobacterium phosphoreum (Sb) against the cells in free suspension for an extended period. The results indicated that both the parameters that were undertaken markedly affected the luminescence. In the study, Sb showed an enhanced luminescence emission than the control up to 18.5‐fold and for a prolonged period which can be efficiently utilized for rapid biosensing of hazardous materials.

Published: April 2023

AbstractA challenge in the pandemic era is to implement effective but flexible practical teaching for biological sciences courses. Such teaching needs to deliver conceptual, analytical and practical skills training while having the option to rapidly respond to health and safety issues, local regulations, staff and student concerns. In this paper, we describe a set of cell biology practicals (mini‐project) that meets many of these requirements and provides flexibility in providing skills training both through online and in practical laboratory environments. We have used a human adenocarcinoma cell line A431 stably transfected with a fluorescent cell cycle reporter as a biological model to deliver training through discrete work packages encompassing cell culture, fluorescence microscopy, biochemistry and statistics. How such work packages can be modified to, an online format either partially or completely is also described. Furthermore, the activities can be adapted for teaching both undergraduate and postgraduate level courses to ensure effective skills training which is applicable to a wide range of biological degree programs and levels of study.

AbstractBackgroundThe present study intended to establish a predictive nomogram for early relapse (ER) (<12 months) after autologous stem cell transplantation (ASCT) in the novel drug era for multiple myeloma (MM).Patients and MethodsThe nomogram was designed and constructed to a retrospective clinical data of newly diagnosed MM patients received novel agent induction therapy and subsequent ASCT at three centers in China from July 2007 to December 2018. The retrospective study was conducted among 294 patients in the training cohort and 126 in the validation cohort. The nomogram's predictive accuracy was evaluated by the concordance index, calibration curve and decision clinical curve.ResultsThe study cohort included 420 newly diagnosed MM patients, and 100 (23.8%) were identified as having ER, including 74 in the training cohort and 26 in the validation cohort. According to the result of multivariate regression in the training cohort, the prognostic variables included in the nomogram were high‐risk cytogenetics, LDH > UNL, and response less than very good partial response (VGPR) after ASCT. The calibration curve showed good fitness between the nomogram predictions and the actual observations and the nomogram was further validated by a clinical decision curve. The nomogram's C‐index achieved 0.75 (95% CI, 0.70–0.80), which was higher than that of the Revised International Staging System (R‐ISS) (0.62), ISS (0.59), and Durie–Salmon (DS) staging system (0.52). The discrimination ability of the nomogram in the validation cohort was superior to that of the other staging systems (C‐index: 0.73 vs. R‐ISS (0.54), ISS (0.55), and DS staging system (0.53)). DCA showed the prediction nomogram adds much more clinical utility. Different scores of the nomogram draw a distinction of OS.ConclusionThe present nomogram could serve as a feasible and accurate prediction of ER in novel drug induction transplantation‐eligible MM patients, which could help modify the post‐ASCT strategy for patients at high risk of ER.

AbstractBackgroundAlthough vimentin is often expressed in non–small cell lung cancer (NSCLC), the association between vimentin expression and immune‐checkpoint inhibitor (ICI) efficacy remains unclear.MethodsThis retrospective multicenter study enrolled patients with NSCLC who received ICI treatment between December 2015 and July 2020. The authors constructed tissue microarrays and performed immunohistochemical staining with vimentin. They analyzed the relationship between vimentin expression rate and objective response rate (ORR), progression‐free survival (PFS), and overall survival (OS).ResultsImmunohistochemically evaluable specimens on microarray blocks were available for 397 patients, of whom 343 (86%) were negative (<10%), 30 (8%) were positive (10%−49%), and 24 (6%) were highly positive (≥50%) for vimentin expression. Both rates of programmed death‐ligand 1 (PD‐L1) tumor proportion score ≥1% and ≥50% were significantly higher in the vimentin‐positive group (≥10%) than the vimentin‐negative group (<10%) (96% vs. 78%, p = .004; 64% vs. 42%, p = .006, respectively). In patients treated with ICI monotherapy, ORR, PFS, and OS were significantly better in the vimentin‐positive group (10%−49%) than in the vimentin‐negative group (<10%) (54% vs. 25%, p = .003, median = 7.9 vs. 3.2 months, p = .011; median = 27.0 vs. 13.6 months, p = .015, respectively), whereas there was no significant difference in PFS and OS between the vimentin highly positive group (≥50%) and the vimentin‐negative group (<10%) (median = 3.4 vs. 3.2 months, p = .57; median = 7.2 vs. 13.6 months, p = .086, respectively).ConclusionsVimentin expression correlated with PD‐L1 expression and ICI efficacy.Plain Language Summary

We constructed tissue microarrays and performed immunohistochemical staining with vimentin on 397 patients with advanced non–small cell lung cancer who were treated with immune‐checkpoint inhibitor (ICI).

The vimentin‐positive group who were treated with ICI monotherapy showed significantly better objective response rate, progression‐free survival, and overall survival than the vimentin negative group.

The measurement of vimentin expression will aid in determining appropriate immunotherapy strategies.

AbstractThe endoscopic management for malignant gastric outlet obstruction has expanded with the advent of endoscopic ultrasound‐guided gastrojejunostomy. Delayed perforation after endoscopic ultrasound‐guided gastrojejunostomy is an important yet rarely reported adverse event, and it is unclear why some patients may suffer this complication. We present a case of intestinal perforation occurring one month after endoscopic ultrasound‐guided gastrojejunostomy and discuss potential mechanisms which may contribute to this outcome.
Differences between stem and branch xylem water isotope composition in four tropical tree species

Published: April 2023

AbstractStable isotope studies (δ2H and δ18O) of water within plants are providing new information on water sources, competitive interactions and water use patterns under natural conditions. This is based on the assumption that there is no fractionation at the time of water uptake or during its transport within trees. However, previous studies have found fractionation does occur in water taken up through the roots in halophytic and xerophytic plants. It is unclear how widespread such fractionation is in other species. In this study, we tested this fractionation by comparing stem and branch xylem water isotopes over the period of one day (from 8 am to 5 pm) in four wet tropical rainforest tree species (Dendrocnide photinophylla,Aphananthe philippinensis,Daphnandra repandulaandMallotus polyadenos). We found branch water isotope ratios (δ2H and δ18O) were enriched compared with stem xylem water isotopes.D. photinophyllahad a significantly different branch δ18O ratio thanA. philippinensis,D. repandulaandM. polyadenos. In contrast, there were no significant differences in stem xylem δ18O among the four observed tree species. We found clear differences in the stable isotope ratios of δ18O for stem and branch xylem water forD. photinophyllaandD. repandulaof upto −0.85% and 0.50%, respectively. Remarkable δ2H differences were also found between stem and branch xylem water isotope ratios forA. philippinensis,D. repandulaandM. polyadenos, being upto −12.14%, −16.17% and −9.65%, respectively. A dual isotope (δ2H–δ18O) plot showed branch water values were more enriched than stem xylem water values forD. photinophyllaandD. repandula, indicating a clear difference between stem and branch xylem water. This study suggests that δ2H and δ18O fractionation could be a species‐specific phenomenon in tropical trees, which has important implications for plant water source identification and evapotranspiration partitioning.
