Impact of Aerosol Shortwave Radiative Heating on Entrainment in the Atmospheric Convective Boundary Layer: A Large-Eddy Simulation Study

Entrainment is critical to the development of the atmospheric convective boundary layer (CBL), but little is known about how entrainment is impacted by the aerosol radiative effect. An aerosol radiation transfer model is used in conjunction with large-eddy simulation (LES) to quantify the impact of aerosol shortwave radiative heating on entrainment and thermodynamics of an idealized dry CBL under aerosol-loading conditions. An entrainment equation is derived within the framework of a zero-order model (ZOM) with the aerosol radiative heating effect included; the equation is then examined against the LES outputs for varying aerosol optical depths (AODs) and free-atmosphere stratification scenarios. The results show that the heat flux profiles become more nonlinear in shape as compared to the case of the clean (no aerosol pollution) CBL, with the degree of nonlinearity being highly dependent on the AOD of the layer for the given type of radiation-absorbing aerosols. As AOD increases, less solar radiation reaches the surface and thus the surface heat flux becomes smaller, and both actual (LES) and ZOM-derived entrainment flux ratios decrease. This trend is opposite to the clean CBL where the LES-predicted flux ratios show an increasing trend with diminishing surface heat flux, while the ZOM-calculated flux ratio remains constant. The modified dimensionless entrainment rate closely follows the −1 power law with a modified Richardson number. The study suggests that including the aerosol radiative effect may improve numerical air quality predictions for heavy-air-pollution events.
Gen periodo no construye filogenias dentro del complejo de especie, Lutzomyia longipalpis (Diptera: Phlebotominae)

espanolEl gen periodo (per) ha sido utilizado ampliamente en estudios de filogenia y evolucion en insectos, en especial con el complejo de especie Lutzomyia longipalpis vector de la leishmaniasis visceral en el neotropico. Dicho gen regula el ritmo de los batidos de las alas utilizado para el cortejo, lo que tiene importancia en procesos de aislamientos reproductivos. En este trabajo se utilizaron las secuencias disponibles en el GenBank del gen per del complejo L. longipalpis, para realizar analisis de metodos de distancia genetica (NJ), maxima parsimonia (MP) y maxima verosimilitud (ML). En general, se obtuvieron bajos soportes estadisticos y grandes politomias en los analisis de distancia y filogeneticos (MP y ML) con todos los grupos de secuencias, lo que evidencia que el gen per no reconstruye filogenias intraespecificas divergentes, y no es lo suficientemente variable para diferenciar especies cercanas filogeneticamente dentro del complejo. EnglishThe period gene (per) has been used in phylogenetic and evolutionary studies on insects, especially within Lutzomyia longipalpis complex species, vector of visceral leishmaniasis on the neotropical region. This particular gene regulates the locomotor activity of the wings during courtship, influencing on reproductive isolations processes. In this work we used DNA sequences of the per gene of L. longipalpis complex available on the GenBank, to make different analyses methods: based on global similarity by genetic distance (NJ), and phylogenies based on cladistic analysis (MP) and probability methods (ML). General results based on all method criteria indicated low bootstrap values and large politomies on the phylogenetic analyses with all set of sequences, all results suggest that the per gen does not reconstruct divergent intraspecific phylogenies within the complex species, and is not enough variable to differentiate species that are near phylogenetically inside the species complex.
Investigating Writing Instruction Practices for Students With Deafness and Hearing Loss

This case study investigated the writing instruction practices of teachers (grades 6 and 7) of students with deafness and hearing loss. The researchers focused on what classroom practices and strategies teachers employed with students, what teachers’ perspectives were about best-practices for writing instruction, students’ perspectives about writing, and scores from their end-of-unit writing samples. The authors completed qualitative interviews and classroom observations with teachers (N=2) and students (N=6; three per class observed) about writing instruction for students with deafness and hearing loss. The data resulted in four themes: the need for teacher modeling, guided practice, and developing students’ independence; students’ challenges with writing (e.g., from ASL to English prose); the need for more resources (e.g., professional development about writing); and how assessment helps define students’ strengths and weaknesses.
Mental Health Prevalence in NCAA Division III Collegiate Athletes

Stressors related to academic requisites, sport participation and pressure to perform may increase college athlete risk for mental health symptoms (Cox, Ross-Stewart, & Foltz, 2017; Sudano & Miles, 2017; Yang et al., 2007). The purpose of this study was to identify the level of clinically relevant self-reported mental health symptoms in National Collegiate Athletic Association (NCAA) Division III athletes and variations based on sport participation (i.e., men’s or women’s athletics; team or individual sports) over a two-year period. A nonexperimental, trend study design was used. Data analysis included descriptive statistics, chi square test, and multivariate analysis of variance (MANOVA) which used one-way analysis of variance (ANOVA) for follow-up procedures. A MANOVA revealed a significant interaction of gender and sport type for general symptoms [F(1, 564) = 9.583, p = . 002] and depression [F(1, 564) = 6.945, p = . 009] but not anxiety [F(1, 564) = 3.332, p = . 068, ƞ2 = . 006]. The project was able to describe mental health symptoms in a population that is not often included in the literature. Knowledge of collegiate athlete mental health prevalence is important because prevention and early intervention is a key component of community-based health programming.
SINGLE-CHANNEL EEG PROCESSING FOR SLEEP APNEA DETECTION AND DIFFERENTIATION

Sleep apnea syndrome is a common sleep disorder. Detection of apnea and diﬀerentiation of its type: obstructive (OSA), central (CSA) or mixed is important in the context of treatment methods, however, it typically requires a great deal of technical and human resources. The aim of this research was to propose a quasi-optimal procedure for processing single-channel electroencephalograms (EEG) from overnight recordings, maximizing the accuracy of automatic apnea or hypopnea detection, as well as distinguishing between the OSA and CSA types. The proposed methodology consisted in processing the EEG signals divided into epochs, with the selection of the best methods at the stages of preprocessing, extraction and selection of features, and classiﬁcation. Normal breathing was unmistakably distinguished from apnea by the k-nearest neighbors (kNN) and an artiﬁcial neural network (ANN), and with 99.98% accuracy by the support vector machine (SVM). The average accuracy of multinomial classiﬁcation was: 82.29%, 83.26%, and 82.25% for the kNN, SVM and ANN, respectively. The sensitivity and precision of OSA and CSA detection ranged from 55 to 66%, and the misclassiﬁcation cases concerned only the apnea type.

Green Synthesis, Characterization and Evaluation of Biological Activities of Ag-Mno Nanocomposites from Cyttaranthus Congolensis.

This study consists of biogenic synthesis of Ag-MnO nanocomposite whose aqueous extract from Cyttaranthus congolensis was used as a reducer and stabilizer. The characterization of these particles by visible UV spectroscopy made it possible to identify the band linked to the surface plasmon resonance located around 380 nm. X-ray Diffraction and Fluorescence made it possible to determine the presence of particles of formula Ag 0.21 Mn 0.28 O having crystallized in a Monoclinic system (a= 5.8517 , b = 3.4674 , c = 5.4838 and β = 107.663°). A spherical morphology was determined by Scanning Electron Microscopy (SEM). The haemolytic activity carried out on human blood made it possible to conclude that Ag-MnO nanocomposites are not toxic to human blood. Moreover, these particles showed good antibacterial activity against gram-positive and gram-negative strains of bacteria. Promising results on anthelminthic activity of Ag-MnO nanocomposites against several pathogenic helmints were reported in this study. Besides antibacterial and antihelmintic activities, Ag-MnO nanocomposites also exhibited good anti-inflammatory and antioxidant activity.
ANALYSIS OF QUALITY CONTROL USING STATISTICAL QUALITY CONTROL METHOD (SQC) IN PT.X

The purpose of this study is to measure the variation of product returns, identify the factors that cause damage to the product by using the statistical qoality control method. statistical quality control is a control process used to collect, analyze, and interpret data used in quality control activities. The tools used in processing data are stratification, pareto diagrams, control charts p, diagram cause and effect. The high product that is returned by consumers can result in losses. Damage to the y product is classified into three types, namely types of spots, rot, bruises. The three types of damage resulted in the product being returned by consumers. The problem must be solved immediately and a solution is sought to handle it. After identifying the types of returns by consumers, then on the Pareto diagram calculating the percentage cost of damage, then the results of the most dominant damage costs due to returns are 66 product variances from 7 types of product, followed by the control chart p. products that are still outside the control limit. The method used in analyzing is a diagram cause and effect.

Relativity from the geometrization of Newtonian dynamics

Based on the Generalized Principle of Inertia, which states that: An inanimate object moves freely, that is, with zero acceleration, in its own spacetime, whose geometry is determined by all of the forces affecting it, we geometrize Newtonian dynamics for any conservative force. For an object moving in a spherically symmetric force field, using a variational principle, conservation of angular momentum and a classical limit, we construct a metric with respect to which the object's worldline is a geodesic. For the gravitational field of a static, spherically symmetric mass, this metric is the Schwarzschild metric. The resulting dynamics reduces in the weak-field, low-velocity limit to classical Newtonian dynamics and exactly reproduces the classical tests of general relativity. We propose a method to extend the theory to handle a gravitational field generated by several sources.
Characterization of beta-lactamase producing Enterobacterales isolated from an urban community wastewater treatment plant in Iran

Background and Objectives: he occurrence and characteristics of Extended Spectrum- and AmpC-β-lactamase producing Enterobacterales (ESBL-PE and AmpC-PE) in an urban wastewater treatment plant (WWTP) were investigated. Materials and Methods: A total of 30 wastewater samples were collected from all sections of WWTP. Enterobacterales were isolated and identified using standard microbiological tests. The antibiotic resistance profile was determined by the Kirby–Bauer disk diffusion method. Phenotypic screening for ESBL-PE and AmpC-PE isolates was performed by double-disk synergy and boronic acid disk potentiation tests, respectively. The isolates were examined for AmpC- and ESBL-encoding genes by PCR and sequencing methods. Results: Among 146 Enterobacterales isolates, 8.9% (n=13) [ESBL-only; 5.48% (n=8) and ESBL + AmpC; 3.42% (n=5)] were ESBL-producers and 15.75% (n=23) [AmpC-only; 12.33% (n=18) and ESBL + AmpC; 3.42% (n=5)] AmpC-producers. Hafnia spp. with 33.33% (n=1/3) and E. coli with 20.58% (n=7/34) [ESBL-only; 17.64% (n=6/34) and ESBL + AmpC; 2.94% (n=1/34)] were the most common ESBL-producing bacteria. Enterobacter spp. with 37.50% (n=6/16) of isolates were the most common AmpC-producing organisms. ESBL- and/or AmpC-producing isolates were identified in all parts of the WWTP including 80% (n=8/10) of samples taken from effluent. Among ESBL-producing isolates, bla CTX-M , bla TEM, and bla SHV ESBL-encoding genes were found in 61.5% (n=8), 15.3% (n=2), and 7.7% (n=1) of isolates, respectively. All CTX-M-type enzymes belonged to the CTX-M-1 group and CTX-M-15 subgroup. bla TEM and bla SHV type genes belonged to bla TEM-20 and bla HSV-12 subtypes, respectively. bla DHA with 73.9% (n=17/23), and bla CIT and bla FOX with 30.4% (n=7/23) each, were the most common AmpC-encoding genes among AmpC-producing isolates. Overall, 75% of ESBL-producing and 55.5% of AmpC-producing isolates exhibited multi-drug resistance phenotypes. The organisms were most resistant against ampicillin (82.2%) nalidixic acid (43.8%) and cephalexin (41.1%). Conclusion: ESBL- and AmpC-producing Enterobacterales spp. with diverse genetic resistance backgrounds in WWTP effluent poses a significant risk to public health.
Molecular characterization of typing and subtyping of Staphylococcal cassette chromosome SCCmec types I to V in methicillin-resistant Staphylococcus aureus from clinical isolates from COVID-19 patients

Background and Objectives: Methicillin resistance is acquired by the bacterium due to mecA gene which codes for penicillin-binding protein (PBP2a) having low affinity for β-lactam antibiotics. mecA gene is located on a mobile genetic element called staphylococcal cassette chromosome mec (SCCmec). SCCmec genomic island comprises two site-specific recombinase genes namely ccrA and ccrB [cassette chromosome recombinase] accountable for mobility. Currently, SCCmec elements are classified into types I, II, III, IV and V based on the nature of the mec and ccr gene complexes and are further classified into subtypes according to variances in their J region DNA. SSCmec type IV has been found in community-acquired isolates with various genetic backgrounds. The present study was undertaken to categorize the types of SCCmec types and subtypes I, II, III, IVa, b, c, d, and V and PVL genes among clinical MRSA isolates from COVID-19 confirmed cases. Materials and Methods: Based on the Microbiological and Molecular (mecA gene PCR amplification) confirmation of MRSA isolated from 500 MRSA SCCmec clinical samples, 144 cultures were selected for multiplex analysis. The multiplex PCR method developed by Zhang et al. was adapted with some experimental alterations to determine the specific type of these isolates. Results: Of the total 500 MRSA, 144 MRSA (60 were CA-MRSA and 84 were HA-MRSA) were selected for characterization of novel multiplex PCR assay for SSCmec Types I to V in MRSA. Molecular characterization of multiplex PCR analysis revealed results compare to the phenotypic results. Of the 60 CA-MRSA; in 56 MRSA strains type IVa was found and significantly defined as CA-MRSA while 4 strains showed mixed gens subtypes. Type II, III, IA, and V were present in overall 84 HA-MRSA. Molecular subtyping was significantly correlated to define molecularly as CA-MRSA and HA-MRSA however 15 (10%) strains showed mixed genes which indicates the alarming finding of changing epidemiology of CA-MRSA and HA-MRSA as well. Conclusion: We have all witnessed of COVID-19 pandemic, and its mortality was mostly associated with co-morbid conditions and secondary infections of MDR pathogens. Rapid detections of causative agents of these superbugs with their changing epidemiology by investing in typing and subtyping clones are obligatory. We have described an assay designed for targeting SSCmec types and subtypes I, II, III, IVa,V according to the current updated SCCmec typing system. Changing patterns of molecular epidemiology has been observed by this newly described assay.
Determining soil moisture regimes for viticultural zoning purposes

This paper aims to analyse the suitability of Soil Taxonomy to characterize the soil moisture regime for viticultural zoning studies, comparing the soil moisture parameters used in the Soil Taxonomy classification with soil moisture parameters relevant to the grapevine phenological stages. The results show that Soil Taxonomy does not adequately reflect the variability of soil moisture dynamics during vineyard growing. Then, a proposal for soil moisture regime classification is realised by means of a cluster analysis. This classification is based on determining dry days, as indicated by Soil Taxonomy, in different vine phenological periods, and grouping the cases according to their variability. The soil moisture regime classes, resulting from cluster analysis, show significant differences in soil moisture status in all phenological periods, and therefore present different implications for viticulture, related to potential for vegetative growth, grape production and the grape ripening process.
Long period morphological dynamics in regulated braided gravel-bed rivers: comparison between Piave River (Italy) and Waitaki River (New Zealand)

Aim of this research has been to make an analysis of long and medium term morphological dynamics that may affect the regulated gravel-bed braided rivers as the Piave river (Italy) and the Waitaki river (New Zealand). The Piave river (drainage area around 4000km2), is one of the largest rivers in the north-east of Italy, the study reach is, mainly, 37 km long, and represent the intermediate course of the river within the mountain district. In addiction were been study different sub-reaches until a minimum of around 1,5 km long. The Waitaki river (drainage area around 11000 km2), is a large gravel-bed river draining the eastern slope of Southern Alps, South Island, New Zealand, has been analyzed along a 13 km long subreach. The flow regime and the sediment supply of these rivers have been considerably altered by hydroelectric dams, flow diversions and, along the Piave river, gravel mining. In addiction, river dynamics have been affected by the construction of stream-bank protection structures. To document these changes, an historical analysis was performed using aerial photographs, cross section survey data and a LiDAR dataset. Morphological features that were examine included planform configuration, active corridor extension, channel width, channel top depth, flow area, number of channels and bed elevation. Vegetation features that were examine included, instead, areal island cover extension and different vegetation class extension. The results indicate as remarkable changes occurred during the study period. In both river there was a marked tendency to the diminution in the number of channels and in the active corridor extension, just subsequently to the main flood events is possible see an increase in the active corridor extensions. Along the Piave river was possible see a marked tendency to narrowing and channel incision during the last 80 years. The island, along both rivers, tend to encroachment and maturation for many years, occupying the active corridor. The island extension could decrease just after considerably flood events (RI > 10 years) or thanks to many close flood events. Regarding islands, has been possible see their tendency to joining with perifluvial vegetation, in consequence of long no-flood periods.
A review of nonparametric attenuation functions computed for different regions of Italy

We used a set of previously published nonparametric attenuation functions to calculate average functions for the Italian region. These nonparametric functions describe the spectral amplitude decay of the S waves as a function of distance for 14 frequencies between 1 and 20 Hz for the regions of Lombardia-Piemonte, Eastern Sicily, Friuli, Marche and the Central Apennines. Since all the attenuation functions were obtained using the same methodology, we were able to make a fair comparison of the attenuation characteristics of the different regions. In general, while the Central Apennines show the strongest amplitude decay for all the frequencies analyzed, the regions of Lombardia and Eastern Sicily show the smallest attenuation. The Marche region also shows a strong amplitude decay, particularly for frequencies f > 3 Hz, and in the frequency band between 1 and 3 Hz the rate of decay of the spectral amplitudes with distance becomes similar to that of the region of Friuli. Since the attenuation functions analyzed represent different geologic and tectonic environments, we used them to calculate an average set of attenuation functions, one per frequency, for the hypocentral distance range between 10 and 120 km. The resulting functions permit a mean attenuation correction to spectral records of S waves in regions of Italy where the specific values of the attenuation parameters are unknown.
