The use of DNA barcoding has revolutionized biodiversity science, but its application depends on the existence of comprehensive and reliable reference libraries. For many poorly known taxa, such reference sequences are missing even at higher-level taxonomic scales. We harvested the collections of the Smithsonian’s National Museum of Natural History (USNM) to generate DNA barcoding sequences for genera of terrestrial arthropods previously not recorded in one or more major public sequence databases. Our workflow used a mix of Sanger and Next-Generation Sequencing (NGS) approaches to maximize sequence recovery while ensuring affordable cost. In total, COI sequences were obtained for 5,686 specimens belonging to 3,888 genera and 202 families. Success rates varied widely according to collection data and focal taxon. NGS helped recover sequences of specimens that failed a previous run of Sanger sequencing. Success rates and the optimal balance between Sanger and NGS are the most important drivers to maximize output and minimize cost in future projects. The corresponding sequence and taxonomic data can be accessed through the Barcode of Life Data System, GenBank, the Global Biodiversity Information Facility, the Global Genome Biodiversity Network Data Portal and the NMNH data portal.

Authors: Saurel-Cubizolles Marie-Josèphe , Aujard Yannick , Claudet Isabelle , Desbiolles Alice , Com-Ruelle Laure , Tilly Anne-Lise , Vandewalle Hélène , Lang Thierry 
Published: March 2022

Objectif : L’article souligne qu’une épidémie virale et les stratégies pour y faire face 1) ont un impact majeur sur des groupes a priori épargnés par la maladie elle-même, ici les enfants, et 2) peuvent générer des problèmes sanitaires au-delà de la maladie et conduire à d’importantes difficultés sociales, économiques, scolaires et à un accroissement des inégalités sociales de santé. Méthode : Les observations présentées se fondent sur la littérature scientifique disponible au premier semestre 2020 et sur des auditions d’acteurs de terrain, d’experts, de responsables d’institutions, menées par un groupe du Haut Conseil de la Santé Publique réfléchissant à une politique globale et concertée pour la santé des enfants. Constats : La crise sanitaire et sa gestion ont retenti sur le développement des enfants et leur qualité de vie. Ces derniers ont été davantage exposés à la sédentarité, aux écrans, aux accidents domestiques, aux violences intrafamiliales. La fermeture des écoles et des lieux de loisirs a entraîné des difficultés scolaires, de socialisation, des atteintes au bien-être psychologique et à la santé mentale. Certains soins curatifs ou préventifs ont été différés. Ces effets se sont produits avec d’importantes inégalités sociales et territoriales. Conclusion : Toute gestion de crise sanitaire exige d’évaluer l’impact global de l’épidémie et des mesures proposées sur des indicateurs sanitaires, économiques, sociaux et scolaires. Cette crise montre la nécessité d’une politique de l’enfance coordonnée, ce qui n’est pas le cas actuellement en France.

ABSTRACT
The electrochromic (EC) smart window is a promising intelligent technology for improving the energy performance of a building. When applying a new glazing material, the window-wall ratio (WWR) is regarded as a significant factor related to daylight and building energy losses. However, there have not been any studies examining the relationship between the efficiency of the EC smart window and the WWR. The aim of this study is to provide strategies for mitigating energy losses and environmental impacts from window elements in an office building. It focuses on optimizing the WWR of EC smart windows to increase building energy efficiency. Double EC, low-emissivity (low-E), and clear glazing materials are simulated combined with five WWRs from 0% to 80% with an interval of 20%, four window orientations, and humid subtropical and Mediterranean climates. The results show that a 40% WWR in a southern-facing building façade using a humid subtropical climate setting provides the optimum energy performance of EC glazing among all the configurations tested. Since it was also found that EC glazing reduces the cooling load, it is more suitable for climate conditions characterized by a hotter temperature with greater solar irradiation. Future research should consider the impact of WWR when balancing thermal, lighting and ventilation requirements, and the properties of EC glazing.
RESPONSIVE KINETIC FAÇADE STRATEGY AND DETERMINATION OF THE EFFECT ON SOLAR HEAT GAIN USING PARAMETRIC BIM-BASED ENERGY SIMULATION
Authors: Salah Fadi , Kayili Merve Tuna 
Published: March 2022

ABSTRACT
This research investigates the potential of kinetic façade reinforcement strategy to reduce the energy consumption of existing buildings in a cold-dominated zone by lowering the cooling load with a mobile solar control system and effective solar control. In this context, a kinetic façade system was proposed for a public building with high transparency in Karabük, Turkey, and the fixed shading elements of the existing building were compared with solar heat gain. For the kinetic façade scenario, the study workflow was developed by a visual programming environment in a Building Information Modeling (BIM) application. The flexible movement of individual kinetic panels was determined by the kinetic panel opening factor and sun path. To determine the effect of typological differences on solar control in the kinetic facade system, horizontal kinetic folded panels and vertical kinetic folded panels were investigated. As a result, a reduction of up to 11.52% was found in solar heat gain during the highest solar radiation intensity days for the existing public building.
Biological notes on immature stages of Hydaticus pacificus conspersus (Coleoptera: Dytiscidae)

Published: March 2022

Abstract
Hydaticus pacificus conspersus Régimbart, 1899 (Coleoptera: Dytiscidae), is currently considered “endangered,” according to the national Red List of Japan. Herein, the developmental period of the immature stages of H. pacificus conspersus during laboratory rearing is described in detail for the first time. We found that this species deposits eggs not only on aquatic plants but also on the surface of driftwood. The observed durations of developmental stages were as follows: egg period – 3 days; first instar – 1–2 days (1.7 ± 0.5); second instar – 1–4 days (2.4 ± 0.6); third instar – 4–7 days (5.0 ± 0.7 days); and construction of a pupal chamber to emergence: 8–13 days (9.6 ± 0.8). Based on these observed results, H. pacificus conspersus has one of the shortest larval developmental periods among the Dytiscidae species. The short larval period and the ability to lay eggs on substrates other than plants may be an adaption of the species to increase reproductive success in unstable environments.

ABSTRACT.
Aedes aegypti plays an important role in the transmission of several arboviruses of medical importance. The availability of information on the blood-feeding preferences of mosquito vectors is a critical step in the understanding of the transmission of human pathogens and implementation of control strategies. In Senegal, no data currently exist on the feeding pattern of Ae. aegypti in urban areas. To fill this gap, Ae. aegypti blood-fed females were collected in five localities by aspiration and using BG Sentinel 2 traps. Collections were carried out monthly between July and November 2019 inside and outside human dwellings. The origin of the blood meal of Ae. aegypti females were identified by an ELISA technique. A total of 1,710 blood-engorged females were examined and showed that Ae. aegypti preferentially fed on human with 78.6% of the identified blood meals. The other blood meals were from animals including dog, cat, horse, cattle, sheep, and rat. This is the first report on the feeding behavior of Ae. aegypti in urban settings in West Africa. It demonstrated that this species is highly anthropophilic.

ABSTRACT.
Malaria transmission has declined substantially in Southern Province, Zambia, which is considered a low-transmission setting. The Zambian government introduced a reactive test-and-treat strategy to identify active zones of transmission and treat parasitemic residents. This study was conducted in the Choma District, Southern Province, Zambia, concurrently with an evaluation of this strategy to identify vectors responsible for sustaining transmission, and to identify entomological, spatial, and ecological risk factors associated with increased densities of mosquitoes. Anophelines were collected with CDC light traps indoors and near animal pens in index cases and neighboring households. Outdoor collections captured significantly more anophelines than indoor traps, and 10 different anopheline species were identified. Four species (Anopheles arabiensis, An. rufipes, An. squamosus, and An. coustani) were positive for Plasmodium falciparum circumsporozoite protein by ELISA, and 61% of these 26 anophelines were captured outdoors. Blood meal assays confirm plasticity in An. arabiensis foraging, feeding both on humans and animals, whereas An. rufipes, An. squamosus, and An. coustani were largely zoophilic and exophilic. Linear regression of count data for indoor traps revealed that households with at least one parasitemic resident by polymerase chain reaction testing was associated with higher female anopheline counts. This suggests that targeting households with parasitemic individuals for vector interventions may reduce indoor anopheline populations. However, many vectors species responsible for transmission may not be affected by indoor interventions because they are primarily exophilic and forage opportunistically. These data underscore the necessity for further evaluation of vector surveillance and control tools that are effective outdoors, in conjunction with current indoor-based interventions.

ABSTRACT.
Trachoma is the leading infectious cause of blindness. In 2016, Morocco was validated by WHO as having eliminated trachoma as a public health problem. We evaluated two previously endemic districts in Morocco for trachomatous inflammation—follicular (TF), trachomatous trichiasis (TT), and antibodies against Chlamydia trachomatis, the causative agent of trachoma. Community-based cross-sectional surveys in the districts of Boumalene Dades and Agdez included 4,445 participants for whom both questionnaire and serology data were available; 58% were aged 1–9 years. Participants had eyes examined for TF and blood collected for analysis of antibodies to the C. trachomatis antigen Pgp3 by both a multiplex bead assay (MBA) and lateral flow assay (LFA). Seroconversion rates (SCR) per 100 people per year were used to estimate changes in the force of infection using Bayesian serocatalytic models. In Agdez, TF prevalence in 1–9-year-olds was 0.3%, seroprevalence ranged from 9.4% to 11.4%, and SCR estimates ranged from 2.4 to 3.0. In Boumalene Dades, TF prevalence in 1–9-year-olds was 0.07%, and modeling data from the different assays indicated a decrease in transmission between 20 and 24 years ago. The TF data support an absence of active trachoma in the two districts examined. However, seroprevalence and SCR in younger people were higher in Agdez than Boumalene Dades, showing that there can be differences in serology metrics in areas with similar TF prevalence. Data will be included in multicountry analyses to better understand potential thresholds for serological surveillance in trachoma.

ABSTRACT. We are aiming in this work to synthesize target molecules not only possess anti-tumor activities but also kinase inhibitors. The target molecules were obtained starting from aryl hydrazones of cyclohexan-1,3-dione followed by its heterocyclization reactions to produce anticancer molecules. The multi-component reactions of the arylhydrazocyclohexan-1,3-dione derivatives 3a-c produced the 1,4,5,6,7,8-hexahydroquinoline derivatives 6a-r and the 4,5,6,8-tetrahydrochromeno[2,3-c]pyrazole derivatives 10a-c. Other multi-component reactions were demonstrated. The anti-proliferative activity of the synthesized compounds toward the six cancer cell lines namely A549, H460, HT-29, MKN-45, U87MG, and SMMC-7721 was studied. In addition the c-Met enzymatic activities and inhibition toward the prostate cancer cell PC-3 were measured. The results obtained in most cases, indicated that the presence of electronegative Cl group through the molecule favour the inhibitions.

ABSTRACT. The aim of present study was the uses of a series of α,β-unsaturated carbonyl compounds (chalcones), in the synthesis of pyridine, pyran, thiophene, thiazole, together with their uses in heterocyclic synthesis. The work has resulted in the synthesis of a variety of 2,5-dihydropyridine, hydrazide-hydrazone, thiophene derivatives, coumarin, pyran and thiazolo[4,5-d]thiazole derivatives. The antitumor activities of the newly synthesized products were carried out against three cancer cell lines namely MCF-7, NCI-H460 and SF-268 and normal human cell line WI38. In addition, the inhibitions of most of the synthesized compounds against c-Met kinase were studied and results showed that many compounds were of high inhibitions, and these are considered as promising anticancer agents. The results obtained encouraged further work in the future.

Published: March 2022

ABSTRACT. This study involves synthesis of new substituted of cobalt phthalocyanine derivatives (CoPc) from starting materials naphthalene-1,4,5, tetracarbonic acid dianhydride (NDI) and phthalic anhydride by dry process. Nano composites materials were prepared from multi wall carbon nanotubes (MWCNTs), and MO (Cr2O3-NiO) to yield (MWCNTs/MO) nanocomposite and mixed with cobalt phthalocyanine to yield (MWCNTs/CoPc-MO). These materials were investigated using different analytical and spectrophotometric methods such as FTIR spectroscopy, X-rays diffraction (XRD), and scanning electron microscopy (SEM). Then the activity of these materials was investigated by conducting photocatalytic oxidation of butann-2-ol over a suspension of these composites under irradiation with UV light from middle pressure mercury lamp. The concentration of the produced 2-butanone was followed by spectrophotometric method using 2,4-dinitro phenyl hydrazone which was detected by measuring absorbance at 480 nm. Different reaction conditions and parameters were investigated such as effect of weight of the catalyst, temperature of reaction, reaction period and the effect of pH of reaction mixture.

Published: March 2022

ABSTRACT. In dye-sensitized solar cells, transparent metal oxide working electrodes play a vital role in defining the power conversion efficiency. It was found that the size of nanoparticles influences the electrical, optical properties of these electrodes. Herein, we describe the synthesis of ZnO with zinc acetate dihydrate and different stabilizers (diethylamine and triethylamine) by using a modified solvothermal process. The obtained materials were characterized by XRD, SEM, EDX, TEM, HRTEM, UV-visible, FTIR, and Raman methods. The crystallite sizes for ZnO-1 and ZnO-2 samples were indexed as 39.0 and 40.5 nm for the highest peak intensity with diethylamine and triethylamine stabilizer, respectively. We examine the effect of stabilizers on the morphology, optical band gap, and photovoltaic performance of the prepared ZnO. We found that ZnO prepared using diethylamine stabilizer exhibiting significant efficiency of 1.45%, open-circuit voltage 0.454 V, short-circuit current density 2.128 mA/cm2, and 0.66 fill factor were achieved under 44 mW/cm2 illumination powers with dye-3.

Investigation of turbidity removal and energy consumption from pistachio processing industry wastewater by electro-oxidation process
Authors: Fil Baybars Ali , Günaslan Sermin 
Published: March 2022

ABSTRACT. In this study, it was aimed to remove turbidity, which is an important parameter of water quality, and to examine energy consumption from pistachio processing industry wastewater (PPIW). As working parameters, mixing speed, supporting electrolyte (SE) type and concentration, initial pH value of wastewater, and current density were examined. Graphite was used as the anode material, and stainless steel was used as the cathode material. The highest removal for the mixing speed parameter was achieved at 400 rpm, the maximum efficiency for the SE type was achieved at NaCl, a concentration of 2 M for the SE concentration, a pH of 3.0 for the wastewater initial pH value, and a current density of 30 mA/cm2. However, considering the energy consumption cost in these parameters, the optimal conditions were determined as 1.25 M of SE, pH 3.0, mixing speed of 400 rpm, and current density of 6 mA/cm2. In these conditions, the turbidity removal efficiency was found to be 90.61%. Energy consumption for the same conditions is calculated at 180 kWh/m3. In the results obtained, it is observed that energy consumption decreases as the concentration of SE increases. NaCl, which is the electrolyte that provides maximum efficiency in removing turbidity, is also the electrolyte that provides minimum energy consumption. In electrochemical systems, the cost is as important as lifting efficiency. Therefore, the choice should be made, considering which of these two parameters will be the priority.
