Abstract
This paper discusses the source area-weathering and tectonic settings of alluvial sediments from Lake Chad Basin (LCB). The grain size distribution has been performed by the Robinson-Kӧln's pipetting method. An HACH-HQ11d brand electric pH meter measures the pH and Eh values. Some sand grains and aggregates were examined by scanning electron microscopy with an Energy Dispersive Spectroscopy. The bulk mineralogy was performed with X-TRA Thermo-ARL Diffractometer. The geochemistry of whole samples was assessed by X-ray Fluorescence Spectrometry. Four profiles constituted of different levels characterized by variation in colors and textures have been examined. The textural variation is linked to the alternation of wet and dry periods in the LCB. Microtextural observations reveal sub-rounded to angular particles with secondary silica precipitation on their surfaces. This suggests fluvial transport and short periods of aeolian movements. The clayey and clayey sandy facies are dominated by kaolinite, quartz and illite while the sandy samples are dominated by quartz, kaolinite, illite, goethite and rutile. Amount major elements, SiO2, Al2O3 and Fe2O3 have the highest contents and this is consistent with the mineralogical composition. The sediments are mature and classified as Fe-shale, Fe-sand and (sub)litharenite. The sediments are formed under oxic paleoenvironmental conditions. The rock sources underwent variable degree of weathering which reveals the impact of climate change prevailing in LCB. The trace element distribution shows no chemical differentiation as a result of low sediment recycling. Most of the discriminant plots indicate a felsic nature of the original sources rocks. The samples plot in the fields of passive margin and collision in a lesser extent. The collision setting may be related to the complex history of felsic source rocks which derived from the Pan African orogeny and the Cameroon Volcanic Line activities.

Abstract
Historically, hazard literature has used social vulnerability to describe how social stratification, based on race, income, education, gender, and other factors, differentially affects the risks and impacts that a given community experiences in a disaster event. Disaster literature also indicates that racially or socially marginalized communities often live in environments that have inadequate protective measures in place against disasters. Recent studies exploring green stormwater infrastructure (GSI) distribution from the perspective of environmental justice show that a high distribution of GSI, which can mitigate the impacts of flooding, significantly correlates with better-resourced communities. However, those studies do not show whether marginalized communities with less access to protective GSI are socially vulnerable or whether the vulnerable communities are relatively excluded from the flood mitigation benefits of stormwater infrastructure, linking the distribution of infrastructure only to specific socio-economic factors. Expanding the Pressure and Release (PAR) model of hazards and social vulnerability, this study explores the relationship between community social vulnerability and grey and green stormwater infrastructure distribution in Washington, D.C. by analyzing the correlation between social vulnerability indices, landscape and urbanization factors, and stormwater infrastructure capacity. The analysis reveals that both grey and green infrastructure capacity has statistically significant negative correlations with population density, imperviousness rate, and social vulnerability, suggesting that grey and green infrastructure is not equitably distributed throughout the city and that the areas of DC housing communities most vulnerable to disaster are those least served by DC’s grey and green infrastructure. Our findings show that the infrastructure separation from planning could raise an equity issue in terms of flooding and give support to the role of infrastructure as a mechanism that deepens social vulnerability. These findings require a broader role of planning that includes urban infrastructure elements and more collaborative works with engineers.

Abstract
Alternative practices to the conventional production system improve soil quality and the sustainability of the environment. The objective of this work was to evaluate the effect of green manure in cover associated with the use of organic compost on lettuce and carrot yield in succession. The experimental design used was in randomized blocks and the treatments were represented by different fertilization managements: spontaneous plants, sunn hemp, lablab, sunn hemp + compost, lablab + compost, organic compost, conventional and control (without fertilization and with periodic removal of spontaneous plants). The study was conducted in a succession system between green manure crop and lettuce and carrot crops. Lettuce grown in succession to lablab and sunn hemp with the addition of organic compost produced more fresh weight than unfertilized and equal to or like the conventionally fertilized lettuce. In these crops, lettuce also presented better quality up to 72 h after harvest. The compost added to the sunn hemp increased lettuce production equaling production with conventionally fertilized plants. Fertilization with lablab, lablab + compost and sunn hemp + compost increased the N, P and K concentration in lettuce plants, equaling the conventionally fertilized plants. The production of marketable carrot roots fertilized with lablab, with and without the addition of compost, was equal to the production with conventional fertilization and, in addition, in these crops were also observed the lowest percentages non-marketable. The results show the potential of lablab and sunn hemp organic compost added in successive production systems.

Published: May 2023

Abstract
Conveyor belt is one of the important equipment for ore mining and transportation, which runs smoothly and has high efficiency. However, if the blockage occurs in the transportation process, it will greatly affect the safety of mine production, and even threaten the lives of miners. Therefore, it is difficult to develop a segmentation network algorithm for anti-clogging control that can be applied to the ore conveyor belt. In order to ensure the accuracy of image segmentation task and the speed of network, an improved Fast-SCNN and U-Net method based on channel concern mechanism is proposed in this paper. The accuracy of image segmentation is considered while the speed of network is guaranteed. The improved network of Fast-SCNN and U-Net with better segmentation effect is applied to the segmentation detection system of high-speed and low-speed conveyor belt, and the key frames of the ore conveyor belt in operation are extracted. The material coverage ratio of the conveyor belt in operation is obtained by segmenting the key frame image. Finally, this paper proposes for the first time an anti-clogging method for ore conveyor belt based on static image detection. By judging and predicting the blockage of ore conveyor belt, the fuzzy algorithm is used to control the running speed of the conveyor belt, and the conveyor belt is quickly and accurately slowed down and stopped when it is going to be blocked or has been blocked, so as to avoid serious blockage. Experiments show that the proposed method can improve the safety and efficiency of ore conveyor belt production.

Abstract

One important continuing effort to tackle the global menace of cardiovascular disorders is the search for more effective and tolerable inhibitors of angiotensin-converting enzymes (ACE). The invaluable role of medicinal plants is known, however, investigation of plant phytochemicals is required for insight into the specific potential of individual components. Appreciating the enormity of the time and resource costs of other conventional approaches, we employed a faster and cheaper yet effective computational approach necessary for the early stages of drug discovery. We aimed to predict the inhibitory potential of 27 phytochemicals from 3 antihypertensive medicinal plants against ACE; their pharmacokinetics and toxicity profile. Herein, AutoDockVina was used for molecular docking to evaluate binding poses and energy scores, admetSAR and SWISSADME for pharmacokinetics parameters, and SPARTAN software for quantum mechanics analysis. Twelve of the 27 phytochemicals showed similar biomolecular interactions in their binding poses and comparable binding scores. Umuhengerin, 5,7,2',5'-Tetrahydroxy-3,4'-dimethoxyflavone 5'-acetate, and benzoylnorecgonine, all with ΔG values of -7.7 kcal/mol and corymbosin (ΔG -7.8 kcal/mol) also demonstrated appreciable energy gap values, indicating their reactivity potential. The compounds showed various pharmacokinetics potential denoting that the hit compounds have drug-like properties.. The findings of this study demonstrate the potential of our phytochemicals to inhibit ACE; further evaluations including derivatization studies will be beneficial to explore their potential as novel cardiovascular drugs.

Abstract
Blockchain is essentially a distributed data system involving multiple subjects, which has the characteristics of distribution, transparency, traceability, tamper-resistance, and no need to trust. The "digital government" based on blockchain technology can meet the requirements of data's non-tampering, traceability, security and credibility, distributed storage, privacy protection, etc., and will play an important role in optimizing government service processes, promoting government data sharing, reducing the operating costs of "digital government" and improving the efficiency of government cooperation. In recent years, a large number of effective practices of "blockchain + government services" have emerged, all of which have achieved good social benefits. However, with the in-depth development of the construction site, the performance requirements of the underlying blockchain system are getting higher and higher, and the number of nodes participating in the consensus of distributed systems is gradually increasing. The "how to efficiently and reliably solve the consensus problem of distributed systems" faced by all blockchain systems is becoming increasingly prominent. Based on the most widely used practical Byzantine fault-tolerant algorithm (PBFT) in alliance chain, this paper proposes to improve PBFT with the idea of "hierarchical consensus" and "threshold signature", and proposes a new Byzantine fault-tolerant algorithm (HCTS-BFT) based on hierarchical consistency and threshold feature BFT. Through further mathematical and statistical analysis, it can be proved that HCTS-BFT has obvious advantages in reducing network load and improving availability. The experimental results show that HCTS-BFT has better consistency efficiency and usability than PBFT in various common network quality environments, which has a significant research significance on how to solve the consensus problem and further improve the consensus efficiency.

Abstract
Background
Intertrochanteric fracture is a common injury among the elderly population causing fundamental lifestyle derangements, which influences the patients’ social and psychological functioning. We aimed to study the quality of life (QoL) and its different parameters in patients with this type of injury.
Materials and methods
In this cohort study, all patients hospitalized with intertrochanteric fracture and aged above 50 from 2016 to the end of 2020 at the Shahid Beheshti Hospital in Babol, Iran, were included. Patients were managed mostly surgically and in exceptional cases non-surgically, were followed up for at least 12 months after receiving treatment. During the follow-up period, patients were dialed and completed a questionnaire to assess the patients' QoL by the 36-item Short Form Health Survey (SF-36). QoL parameters were analyzed based on patients’ sex, age, type of treatment, and height of fall causing fracture.
Results
A total number of 200 patients including 101 (50.5%) males and 99 (49.5%) females with mean age of patients was 74.76 ± 11.36 years (range: 50–99) were included. Regarding the received treatment, 192 (96.0%) patients underwent surgery, and 8 (4.0%) underwent non-surgical treatment. In the study of SF-36 scores, the mean score of male patients was 42.31 ± 14.58 and females scored 37.83 ± 15.35, and the difference was statistically significant (P = 0.04). The mean score of QoL and its subscales among the patients of the 50–75 group was significantly higher than the 76–99 group (P < 0.001). The average score of QoL was considerably higher in patients who had surgery (40.75 ± 14.57) compared to those who has non-surgical treatment (24.30 ± 19.85) (P = 0.01). Patients having a fall from a higher height had higher QoL after treatment.
Conclusion
This study revealed that patients with an intertrochanteric femoral fracture had a poor QoL in all aspects. The overall QoL was significantly higher among male patients, younger patients, those who underwent surgical treatment, and the falls from higher heights. These findings highlight the necessity of long-term follow-up and support in patients with intertrochanteric fractures.

Abstract
In Algeria, the data and research on the essential and toxic chemical elements in food are limited and insufficient, therefore the present study focused on evaluating the essential and toxic elements content in different 11 brands with two types (tomato and oil) of canned tuna fish, sold in Algeria in 2022, by inductively coupled plasma-optical emission spectrometer (ICP-OES), while Mercury (Hg) levels were determined by cold vapor atomic absorption spectrophotometry, as well as estimate the probabilistic risk assessment. The element in canned tuna fish commercialized for human consumption in Algeria as (Ca, Cd, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Zn and As) were determined by ICP-OES methods, while, the toxic elements of Mercury (Hg) levels were determined by cold vapour atomic absorption spectrophotometry. The levels of mineral elements concentration were close to the minimum recommended by Food and Agriculture Organization (FAO). The data obtunded in this work has a rich of mineral elements. Data analyses obtunded for this investigation can be suitable for Algerian food purposes.

Published: May 2023

Abstract
Background Genetic, metabolic, and clinical evidence links lipid dysregulation to an increased risk of Alzheimer’s disease (AD). However, the role of lipids in the pathophysiological processes of AD and its clinical progression is unclear. Our objectives were to investigate the association between cerebrospinal fluid (CSF) lipidome and the pathological hallmarks of AD, progression from mild cognitive impairment (MCI) to AD, and the rate of cognitive decline in MCI patients.Methods We analysed the CSF lipidome by liquid chromatography coupled to mass spectrometry in an LC-ESI-QTOF-MS/MS platform for 209 participants recruited consecutively: 91 AD, 92 MCI, and 26 control participants. Additional characteristic of the study population such as demographic data (age and sex), education, comorbidities, complete blood count, CSF AD biomarkers, MMSE scores and APOE ɛ4 allele were also collected.Results Forty-eight (52.2%) MCI patients progressed to AD during follow-up (58 ± 12.5 months). We found that higher CSF levels of hexacosanoic acid and ceramide Cer(d38:4) were associated with an increased risk of amyloid beta 42 (Aβ42) positivity in CSF, while levels of phosphatidylethanolamine PE(40:0) were associated with a reduced risk. Higher CSF levels of sphingomyelin SM(30:1) were positively associated with pathological levels of phosphorylated tau in CSF. Regarding the progression from MCI to AD, cholesteryl ester CE(11D3:1) and an unknown lipid were recognized as the most associated lipid species. Furthermore, TG(O-52:2) was identified as the lipid most strongly associated with the rate of progression.Conclusion Our results indicate the involvement of membrane and intracellular neutral lipids in the pathophysiological processes of AD and the progression from MCI to AD dementia. These data also suggest that lipid droplets may be involved, as a cause or consequence, in pathophysiological processes underlying neurodegeneration.

Abstract
Background
The aim of this study was to analyze postoperative consumption of analgesics during hospitalization following colorectal surgery for endometriosis.
Methods:
We conducted a retrospective study at Tenon University Hospital, Paris, France from February 2019 to December 2021.
Results
One hundred sixty-two patients underwent colorectal surgery: 89 (55%) by robotic and 73 (45%) by conventional laparoscopy. The type of procedure had an impact on acetaminophen and nefopam consumed per day: consumption for colorectal shaving, discoid resection and segmental resection was, respectively, 2(0.5), 2.1(0.6), 2.4(0.6) g/day (p = 10 − 3), and 25(7), 30(14), 31(11) mg/day (p = 0.03). The total amount of tramadol consumed was greater following robotic surgery compared with conventional laparoscopy (322(222) mg vs 242(292) mg, p = 0.04). We observed a switch in analgesic consumption over the years: tramadol was used by 70% of patients in 2019 but only by 7.1% in 2021 (p < 10 − 3); conversely, ketoprofen was not used in 2019, but was consumed by 57% of patients in 2021 (p < 10 − 3). A history of abdominal surgery (OR = 0.37 (0.16–0.78, p = 0.011) and having surgery in 2020 rather than in 2019 (OR = 0.10 (0.04–0.24, p < 10− 3)) and in 2021 than in 2019 (OR = 0.08 (0.03–0.20, p < 10− 3)) were the only variables independently associated with the risk of opioid use.
Conclusion
We found that neither clinical characteristics nor intraoperative findings had an impact on opioid consumption in this setting, and that it was possible to rapidly modify in-hospital analgesic consumption modalities by significantly reducing opioid consumption in favor of NSAIDS or Nefopam.
Insilico designing of novel imidazothiadiazole derivatives as SGLT2 inhibitors in emerging potential for Antidiabetic Therapeutics
Authors: Mehra Anuradha 
Published: May 2023

Abstract
Background. Deficiency of insulin signaling in type 2 diabetes results from insulin resistance or defective insulin secretion and induce hyperglycemia. By reducing glycated hemoglobin, SGLT2 inhibitors improve hyperuricemia, blood lipids and weight loss without increasing the risk of hypoglycemia. By targeting this pathway, SGT2 inhibitors can become a prominent target in the management of type 2 diabetes.
Objective. Interpretation of molecular docking and physicochemical properties of imidazo (2,1-b)-1,3,4 thiadiazole scaffold as SGLT2 inhibitors.
Methods. The chemical structures of 108 molecules were drawn by using Chemdraw professional 15.0. Further, their energy minimization was also carried out by using Chem Bio Draw three-dimensional (3D) Ultra 12.0. Molecular docking was also carried out using a Molegro Virtual Docker to identify the best-fitting molecules and to identify the potential leads on the basis of dock score. The predicted parameters of drug-likeness according to Lipinski’s rule of five, such as molecular weight, log P, hydrogen bond acceptor, hydrogen bond donors, and number of rotatable bonds of the selected compounds, were predicted using pKCSM software.
Results. 108 molecules were designed by employing different substitutions on imidazo-thiadiazole nucleus as SGLT2 inhibitors. Out of these 10 compounds were found to have better interactions with the active site of SGLT2 protein and the highest dock scores as compared to that of canagliflozin. Compounds 39a and 39b demonstrated good interactions and the highest dock score of -155.428 and -142.786 respectively. The insilicophysicochemical properties of the best compounds had also been determined. Additionally, these compounds suggested a good pharmacokinetic profile as per Lipinski's rule of five (orally active drugs).
Conclusion. The imidazo (2,1-b)-1,3,4 thiadiazole scaffold was employed to design a novel SGLT2 inhibitor that exhibits maximum binding interactions with essential amino acids as well orally active.
