Adsorption of amoxicillin by Mn-impregnated activated carbons: performance and mechanisms

Phragmites australis carbon (PAC) was produced from Phragmites australis by phosphoric acid (H3PO4) activation. To achieve a better amoxicillin (AMX) adsorption performance, manganous dihydrogen phosphate (Mn(H2PO4)2) and manganese chloride (MnCl2) were impregnated, producing PAC-MP and PAC-MC, respectively. Adsorption studies were carried out in different initial AMX concentration (15–100 mg L−1), pH (2–10) and contact time (0–60 h) to evaluate AMX adsorption performance and mechanisms. The adsorption isotherms well agreed with the Langmuir model for the three adsorbents. The maximum AMX adsorption capacity on PAC, PAC-MP and PAC-MC was 110, 132 and 122 mg g−1, respectively. Solution pH had a strong influence on AMX adsorption. For kinetic results, a significant desorption phenomenon was observed. Several possible mechanisms were elaborated which include electrostatic interaction, complexation and degradation of AMX molecules. On the whole, Mn-impregnated PAC showed superior AMX removal efficiency, which presents a promising modification method for activated carbon in the treatment of AMX containing wastewater.
The Mortality Rate and Affecting Factors in Patients with Community-Based Pneumonia Requiring Hospitalization

Objective: The aim of this study is to determine the mortality rate and affecting factors in patients with community-acquired pneumonia (CAP) requiring hospitalization. Material and Methods: 150 cases with CAP were evaluated retrospectively. Age, gender, hospital mortality, presence of concomitant disease, smoking history, history of intensive care unit and invasive mechanical ventilation, hospitalization time, arterial oxygen saturation (SaO2), CURB-65 score, sputum culture results, values of pulse, arterial blood pressure, fever, respiratory rate, confusion status, hemogram, urea, creatinine, C-reactive protein (CRP) and procalcitonin (PCT) values were recorded from our hospital’s database system. Results: The hospital mortality rate was 12.7% (n = 19). The mean age, CURB65 scores, fewer, respiratory rate, neutrophil counts, urea, CRP levels and PCT positivity were statistically increased and SaO2 levels, systolic TA, diastolic TA, lymphocytes and platelet counts were statistically decreased in CAP patients with died in-hospital. Logistic regression showed that need for invasive mechanical ventilation, confusion status and PCT positivity were significantly associated with in-hospital mortality. Conclusion: Advanced age, high neutrophil ratio, high CURB-65 score and low systolic TA values are related factors with hospital mortality in patients with CAP requiring hospitalization. In addition, invasive mechanical ventilation, confusion status and PCT positivity are independent risk factors for hospital mortality in CAP patients.
Crustacean Life Cycles—Developmental Strategies and Environmental Adaptations

Crustacea (or Pancrustacea) have explored virtually all possible milieus in different parts of their life cycle, including freshwater, marine, and terrestrial habitats, and even the air (pterygote insects). Many crustacean taxa display complex life cycles that involve prominent shifts in environment, lifestyle, or both. In this chapter, the overwhelming diversity of crustacean life cycles will be explored by focusing on changes in the life cycles, and on how different phases in a life cycle are adapted to their environment. Shifts in crustacean life cycles may be dramatic such as those seen in numerous decapods and barnacles where the development involves a change from a pelagic larval phase to an adult benthic phase. Also, taxa remaining in the same environment during development, such as holoplanktonic Copepoda, Euphausiacea, and Dendrobranchiata, undergo many profound changes in feeding and swimming strategies. Numerous taxa shift from an early larval naupliar (anterior limbs) feeding/swimming system using only cephalic appendages to a juvenile/adult system relying almost exclusively on more posterior appendages. The chapter focuses mainly on nondecapods and is structured around a number of developmental concepts such as anamorphosis, metamorphosis, and epimorphosis. It is argued that few crustacean taxa can be characterized as entirely anamorphic and none as entirely metamorphic. Many taxa show a combination of the two, even sometimes with two distinct metamorphoses (e.g., in barnacles), or being essentially anamorphic but with several distinct jumps in morphology during development (e.g., Euphausiacea and Dendrobranchiata). Within the Metazoa the Crustacea are practically unrivalled in diversity of lifestyles involving, in many taxa, significant changes in milieu (pelagic versus benthic, marine versus terrestrial) or in feeding mode. Probably such complex life cycles are among the key factors in the evolutionary success of Crustacea.
REVIEW ON ANTIMICROBIAL AND ANTI ACNE POTENTIAL OF KAEMPFERIA SPP.

Acne is a general but somber skin disease, which affects approximately 80% adolescents and young adults in 11–30 age groups. 42.5 % of men and 50.9 % of women keep onto suffer from this disease into their twenties. Bacterial resistance is now at the alarming stage due to the irrational use of antibiotics. Hence, search for new lead molecule/bioactive and rational delivery of the existing drug (for better therapeutic effect) to the site of action is the need of the hour. Plants and plant-derived products have been an integral part of health care system since time immemorial. Therefore, plants that are currently used for the treatment of acne and those with a high potential are summarized in the present review. Most active plant extracts, namely, P. granatum, M. alba, A. anomala, and M. aquifolium exhibit minimum inhibitory concentration (MIC) in the range of 4–50 μg/mL against P. acnes, while aromatic oils of C. obovoides, C. natsudaidai, C. japonica, and C. nardus possess MICs 0.005–0.6 μL/mL and phytomolecules such as rhodomyrtone, pulsaquinone, hydropulsaquinone, honokiol, magnolol, xanthohumollupulones, chebulagic acid and rhinacanthin-C show MIC in the range of 0.5–12.5 μg/mL. Novel drug delivery tant plant leads in the treatment of acne have also been discussed.
Psychometric Adaptation of a Japanese Version of the Feelings Towards Group Work Questionnaire for Use in the Japanese SLA Context

This measurement study reports on the adaptation of the Feelings Towards Group Work questionnaire (FTGW; Cantwell & Andrews, 2002) into the Japanese population and second language acquisition domain. The original English version of the instrument was translated into Japanese, and this was then back-translated into English and compared to the original to ensure that the language used was equivalent. A data set (N = 307) was collected from university students at two universities in western Japan. Normality of test items was examined, and reliability estimates (Cronbach's alpha) of the three subscales that make up the instrument were calculated. Confirmatory factor analysis (CFA) was conducted to test the fit of the threefactor model hypothesized by the authors of the instrument, and the evidence was negative. Subsequent, and diagnostic, CFAs of the separate subscales indicated that the model fit for the scores on two of the subscales (Preference for Individual Learning and Preference for Group Learning) was unsatisfactory while the fit on the remaining subscale (Discomfort in Group Learning) was exemplary. The implications of these results for this adapted version of the FTGW questionnaire are discussed. Introduction The use of pair-work and group activities has been on the increase in the English as a second language classroom (Fushino, 2010) and has become an accepted part of most teacher's practice. This is not surprising considering the benefits that have been reported in the literature for group-based learning approaches. By working in pairs or small groups, learners can act as mediators who help to explain new ideas or information to co-learners (Gillies, 2003). In addition to facilitating language learning, members of a group can also serve as a pool of resources, as sources of motivation and as a base of support for each other (Dornyei & Malderez, 1997). More broadly, small group learning approaches can improve the quality of students’ interactions with their peers while at the same time helping them to develop their academic skills, build selfesteem and improve their overall attitudes towards learning (Johnson, Johnson & Smith 1998; 220 Larry J.

Bulletins et mémoires de la Société d’Anthropologie de Paris

We present a comparative study of the Tighennif (Algeria) and Gran Dolina-TD6 (Spain) hominin mandibles, which represent two geographically near and contemporaneous populations separated by the Mediterranean sea, in order to test the hypothesis that these populations belong to the same evolutionary lineage, as it has been suggested by some authors. The Tighennif mandibles show a clear primitive structural pattern, derived in some features with regard to the oldest Homo specimens from H. habilis, as well as from the Javanese H. erectus. In addition, the Tighennif specimens share all these derived features with H. ergaster and, some of them, with H. antecessor. However, the Gran Dolina-TD6 specimens are remarkably smaller than those of Tighennif, and lack the robustness which characterizes the African Pleistocene mandibles. The main difference between both groups in terms of mandibular dimensions can be related to the higher corpus height characteristic of Tighennif specimens. The dental evidence reveals that North African Middle Pleistocene populations are morphologically closer to African Early Pleistocene populations than to TD6 fossils. We conclude that the Spanish and Algerian hominins belong to different hominin lineages. The Tighennif hominins, together with other contemporaneous (Thomas Quarry and Oulad Hamida 1), and perhaps later North African specimens (Sidi Abderrahaman, Salé, and Rabat [Kebitat]) should be considered as a subspecies of the H. ergaster species, i.e. H. ergaster mauritanicus, and may be the result of an evolution in isolation in this African area. In agreement with the mandibular and dental evidences, the Gran Dolina-TD6 hominins could belong to an exclusive Eurasian lineage.
AN INVESTIGATION AND ANALYSIS OF SURFACE ROUGHNESS AND TOOL WEAR IN DRY POCKET MILLING OF ALUMINUM ALLOY AL7075

This study was conducted to investigate the influence of milling parameters and machining time on the surface roughness and tool wear. The experimental was designed and conducted with three controllable factors-three levels (axial depth of cut, feed rate, and cutting speed) in dry pocket milling processes of aluminum alloy Al7075. Performance measurements that were chosen to perform were surface roughness and tool wear at three machining time (after 90 minutes machining, after 180 minutes machining, and after 270 minutes machining). The effect of cutting conditions on the surface roughness and tool wear were analyzed and evaluated. In almost cases, the most significant factor that influnced on the surface roughness and tool wear as well was feed rate (from 54.78% to 62.27 % for roughness surface and from 70.71 to 87.15 % for tool wear). Linear regression that was determined as the most suitable regression of tool wear and surface roughness with the determination coefficients (R) from 95.12 % to 96.14 % for tool wear, and from 91.27 % to 96.18 % for surface roughness. These regression models were successfully verified by comparison of predicted and measured results of tool wear and surface roughness. Besides, the influence of the machining time on the surface roughness and tool wear was also investigated with the interesting results. Moreover, the relationship between surface roughness and tool wear was also analyzed. Tool wear, surface roughness models, and their relationship can be used to improve the surface quality and the tool life in dry pocket milling the aluminum alloy Al7075.

Graduating during a recession: A literature review of the effects of recessions for college graduates

The COVID-19 pandemic has caused a halt of the economy worldwide. The U.S. job market experienced an unprecedented downturn due to the pandemic-caused recession beginning in March 2020. As a consequence, thousands of jobs across industries now face wage cuts. The unemployment rate rose above 20% in April with a temporary layoff share close to 80% (Bartik, 2020; Cajner et al., 2020). The future of hundreds of thousands of college graduates transitioning from college to the labor market has thus become a matter of great concern for students, career advisors, higher education officials, and policy makers.
STUDIES ON THE INTRARETINAL ACTION POTENTIAL PART I. RELATION BETWEEN THE LOCALIZATION OF MICRO-PIPETTE IN THE RETINA AND THE SHAPE OF THE INTRARETINAL ACTION POTENTIAL

Intraretinal action potential was successfully recorded by means of micropipetteinserted into the retina. The localization of the electrode in the retina could be determined by a characteristic potential change during the insertion of electrode. It was found that the shape of the action potential thus detected intraretinally differs remarkably according to the localization of the electrode, considerations on which have led to a belief, that P I and the resting potential originate in most certainty in the receptors layer, and that P III originates in bipolar cells layer. Reports on the nature of the negative potentials intraretinally detected and on P II localization were left to succeeding papers.

A STUDY OF HAEMATOLOGICAL MANIFESTATIONS OF SLE WITH SPECIAL REFERENCE TO DISEASE ACTIVITY

Background: Our understanding of Systemic Lupus Erythematosus (SLE) has been evolved very significantly over the period of last few decades. The hematological abnormalities though more commonly seen are not properly evaluated or estimated and are not given enough representation . In some of these cases presenting with Anaemia, Thrombocytopenia, Pancytopenia or Thrombotic episodes, especially so in young females, the diagnosis may be delayed or initially missed if the index of suspicion is low or if there is improper and inadequate follow up. Thus keeping this in mind this study as be carried out. Aim and Objectives :(1) To study Haematological manifestations of SLE and (2) To study its correlation with the disease severity. Materials and Methods: This study is an Observational Cross Sectional Study done in Assam Medical College for a period of one year. All cases who fulfilled the ACR criteria 1997 who came to Rheumatology opd and those who admitted in Medicine ward taken up for the study. Results: Totally 106 patients were taken up for the study. The most common constitutional symptom was Fatigue which present among 57 (53.7%). Raynaud ’s phenomenon was present among 15(14.15%) patients. Anaemia was present in 99 patients (93%) of the study group with most common type being Anaemia of chronic disease. Neutropenia was present among 8 (7.5%), Thrombocytopenia among 8(7.55%) in the study group. Severity of anaemia and Serum Ferritin Level were in correlation with the Disease severity (SLEDAI). Conclusion: Haematological Manifestations is one of the most common manifestation presents very early in the disease process and in many cases as the only presentation. This Study demonstrated similarities with most of other studies, revelling at the same time much Higher incidence of Haemotological manifestations compared to other studies.
Consumer Intention Index in Batik Industry Using Structural Equation Modeling

This is a continuation of previous research conducted by the same researchers. However, apart from including subjects from Malaysia, the antecedent variables are different. All variables were measured using a Likertscale with the scores ranging from 1 to 10. The convergent and discriminant validity, as well as the reliability of the instrument were tested empirically. From the results, it is known that trust has a direct effect on intention. In addition, both perceived value and perceived quality have a direct or indirect effect towards intention through trust. At the end of this article, suggestions for future research are also presented.
Measurements of losses on three-core submarine power cables

Armour losses are calculated during the design process of submarine cables using IEC 60287-1-1 formulae. Several recent papers underline the possible overestimation of armour losses given by IEC standards. In this paper, armour losses are investigated on two different High Voltage (HV) three-core submarine power cables. Measurements have been made in air and in salt water and results are compared to IEC 60287 calculations.
Parameter Selection: Why We Should Pay More Attention to It

The importance of parameter selection in supervised learning is well known. However, due to the many parameter combinations, an incomplete or an insufficient procedure is often applied. This situation may cause misleading or confusing conclusions. In this opinion paper, through an intriguing example we point out that the seriousness goes beyond what is generally recognized. In the topic of multilabel classification for medical code prediction, one influential paper conducted a proper parameter selection on a set, but when moving to a subset of frequently occurring labels, the authors used the same parameters without a separate tuning. The set of frequent labels became a popular benchmark in subsequent studies, which kept pushing the state of the art. However, we discovered that most of the results in these studies cannot surpass the approach in the original paper if a parameter tuning had been conducted at the time. Thus it is unclear how much progress the subsequent developments have actually brought. The lesson clearly indicates that without enough attention on parameter selection, the research progress in our field can be uncertain or even illusive.
PlexNet: An Ensemble of Deep Neural Networks for Biometric Template Protection

The security of biometric systems, especially protecting the templates stored in the gallery database, is a primary concern for researchers. This paper presents a novel framework using an ensemble of deep neural networks to protect biometric features stored as a template. The proposed ensemble chooses two state-of-the-art CNN architectures i.e., ResNet and DenseNet as base models for training. While training, the pre-trained weights enable the learning algorithm to converge faster. The weights obtained through the base model is further used to train other compatible models, generating a fine-tuned model. Thus, four fine-tuned models are prepared, and their learning are fused to form an ensemble named as PlexNet. To analyze biometric templates’ security, the rigorous learning of ensemble is collected using a smart box i.e., application programming interface (API). The API is robust and correctly identifies the query image without referring to a template database. Thus, the proposed framework excludes the templates from database and performed predictions based on learning that is irrevocable.

Tribological investigation of applicability of nano-sized cupricoxide (CuO) ceramic material in automotive vehicles

Due to the continuously increasing requirements of the internal combustion engines, the lubricants and their additives have to be further developed. One possible solution is the application of ceramic nanoparticles as friction modifier and wear decreaser additives. This paper presents the tribological investigation of cupricoxide (CuO) nanoparticle mixed in neat Group 3 base oil. To analyse its properties, simplified ball-on-disc friction experiments were carried out in the tribological laboratory in the Széchenyi István University in Győr, Hungary. The arisen wear scars were analysed with different, highresolution microscopes to understand the working mechanism of the nanoparticles. The results have indicated an optimum concentration of nanoparticles at 0.5wt% where both the average friction coefficient and the wear scar diameter were reduced by 15%. The microscopical investigation revealed the reduction of copper material from the CuO material, and it has mended to the rubbing surface forming a protective film on the metal surface.
