Spectral, biological screening, and DNA studies of metal chelates of 4-[N,N-bis-(3,5-dimethyl-pyrazolyl-1-methyl)]aminoantipyrine

Tridentate chelate complexes of Co(II), Ni(II), and Cu(II) have been synthesized from 4-[N,N-bis-(3,5-dimethyl-pyrazolyl-1-methyl)]aminoantipyrine. Microanalytical data, UV-Vis, magnetic susceptibility, Infrared, 1H- 13C-NMR, mass, thermal gravimetric analysis and electron paramagnetic resonance (EPR) techniques were used to confirm the structures. The electronic absorption spectra and magnetic susceptibility measurements suggest a distorted octahedral geometry for the metal. EPR spectra of the copper(II) complex at 77 K confirm the distorted octahedral geometry of the copper(II) complex. The antimicrobial activities of the ligand and metal complexes against the bacteria such as Xanthomonas maltophilia, Chromobacterium violaceum, Acinetobacter, Staphylococci, Streptococci, and the fungus Candida albicans have been carried out. A comparative study of minimum inhibitory concentration values of the ligand and its metal complexes indicates that metal complexes exhibit higher antibacterial and antifungal activity than the free ligand. The electrochemical behavior of copper(II) complex was studied by cyclic voltammetry. The complexes show nuclease activity in the presence of oxidant.
Optimization and characterization of the photosensitive N-succinyl-N’-4-(2-nitrobenzyloxy)-succinyl-chitosan micelles

With the copolymer micelles being widely used in the field of tumor therapy, environmental responding copolymers had gained large interest. In our previous work, we synthesized the nanovehicle N-succinyl-N’-4-(2-nitrobenzyloxy)-succinyl-chitosan micelles (SNSC) that were composed of a light-sensitive triggering group 2-nitrobenzyl alcohol on the hydrophobic block and succinyl group modified chitosan. We have demonstrated that the use of a continuous-wave diode near-infrared (NIR) laser could cleave the amphiphilic block copolymer micelles and trigger the release of their “payloads”. In the present study, SNSC were further optimized and characterized by UV-visible spectroscopy, fluorescence spectroscopy and transmission electron microscopy (TEM) that was used to display the two-photon photolysis of SNSC micelles under the NIR irradiation (765nm) . Later on, laser confocal fluorescence microscopy was used to investigate the fluorescein (Ex/Em: 490/520 nm)-loaded SNSC imaging ability. As a result, the optimized SNSCs exhibited higher loading efficiency and smaller size which contributed to an improved stability, drug delivery and cell imaging abilities.

Textile Technology for Soft Robotic and Autonomous Garments

Textiles have emerged as a promising class of materials for developing wearable robots that move and feel like everyday clothing. Textiles represent a favorable material platform for wearable robots due to their flexibility, low weight, breathability, and soft hand‐feel. Textiles also offer a unique level of programmability because of their inherent hierarchical nature, enabling researchers to modify and tune properties at several interdependent material scales. With these advantages and capabilities in mind, roboticists have begun to use textiles, not simply as substrates, but as functional components that program actuation and sensing. In parallel, materials scientists are developing new materials that respond to thermal, electrical, and hygroscopic stimuli by leveraging textile structures for function. Although textiles are one of humankind's oldest technologies, materials scientists and roboticists are just beginning to tap into their potential. This review provides a textile‐centric survey of the current state of the art in wearable robotic garments and highlights metrics that will guide materials development. Recent advances in textile materials for robotic components (i.e., as sensors, actuators, and integration components) are described with a focus on how these materials and technologies set the stage for wearable robots programmed at the material level.
A Case Study of One Inclusive Recreation Course

Abstract Diversity and inclusion courses are common components of undergraduate leisure studies curricula. Although a body of diversity and inclusion content has been developed, few detailed course structures have been shared. I share the learning outcomes, course units, lecture topics, assigned readings, and key assignments from my inclusive recreation class in this essay. Lessons learned while teaching this course are also shared to facilitate both critique and utilization of these materials. Course materials are shared in the interest of inciting others to share their approach to diversity and inclusion courses so that a wider dialogue on what effective instruction of those courses looks like might begin. I close the essay with reflections and lingering questions on the teaching of diversity and inclusion in leisure studies.
Prevalence of Helicobacter pylori infection among children with primary nephrotic syndrome: a cross-sectional study

Background Limited data are available about the prevalence of helicobacter pylori (H.pylori) infection among primary NS children. Objectives To assess the frequency and risk factors of H.pylori infection among children with primary NS. Methods A cross-sectional study was carried out in Mansoura University Children's Hospital, Egypt during the period from 2017 to 2019 including 100 NS children (NS group) and 100 healthy controls. NS group included 88 steroid sensitive (SSNS) and 12 steroid resistant (SRNS) cases. All patients were assessed for H.pylori infection using H.pylori stool antigen (HpSA) test. Statistical analysis was done using chi-square, fisher exact and Mann-Whitney tests. Results With regard to HpSA test results, no significant differences were detected between control and NS groups (p = 0.193) and between SSNS and SRNS groups (p = 0.286). Concerning total biopsied cases and MCD (proven plus presumed) cases, no significant differences were found between those with positive and negative HpSA test (p = 0.648 and 0.126, respectively). The high dose of steroid therapy was associated with a higher risk of H.pylori infection among NS group (Odds ratio = 3.8; 95% confidence interval = 1.3–11.3). Conclusion The current study negates the increased risk of H.pylori infection in children with primary NS.
HUMAN RESOURCES COMPETENCIES AND THE MEDIATION ROLE OF THE ORGANIZATIONAL CLIMATE

The present study aimed to determine the effect of human resources competency levels on organizational structure, and also to identify the mediation role of the organizational climate in this effect. The relationship among these variables was analyzed by statistical methods such as factor analysis, regression analysis, and Sobel tests. All academic and administrative employees in a state university operating in Mersin Province of Turkey were included in the study. Data, collected using a questionnaire developed by the researchers from all employees of the university, were used to determine the relationship between the variables in the study. It was found in the present study that the levels of human resources competence positively affect organizational structure, and the organizational climate has a partial mediation effect in this relationship.
A Study of the Interaction between Single-Walled Carbon Nanotubes and Polycyclic Aromatic Hydrocarbons: Toward Structure−Property Relationships

The interaction between polycyclic aromatic hydrocarbons (PAHs) and single walled carbon nanotubes (SWNTs) has been studied by fluorescence spectroscopy. Fluorescence quenching as a function of concentration is modeled, revealing regions where the interaction causes a debundling of the carbon nanotubes. The binding energies between PAHs and SWNTs are obtained from the model. It is found that there is a linear correlation between the binding energy of PAHs with SWNTs and the molecular weight of the PAHs. By plotting these values of binding energy against the molecular weight of these PAHs, a good structure−property relationship governing the interaction has been demonstrated.
Does negatively toned language use on social media lead to attitude polarization?

Prior research has indicated that both attitudinal homogeneity of communication networks (“echo chambers”) and attitudinal heterogeneity of communication networks (“adversarial debates”) can lead to attitude polarization. The present paper argues that communication in both echo chambers and adversarial debates is dominated by network negativity, a negative valence in the tone of discussions which might be associated with attitude polarization. Combining methods from sentiment analysis and social network analysis, more than 4 million tweets on two controversial topics (Brexit, Trump) were analyzed to investigate the association between network negativity and two proxies of attitude polarization (extremity and ambivalence). Results indicate that negativity in users’ own tweets was most strongly related to polarization, whereas negativity among users’ friends, or consonance of sentiments between users and friends had less impact on polarization. The findings are related to literatures on negativity bias, optimal distinctiveness theory, and intergroup contact theory.
Orientation of Polyelectrolyte Multilayers Containing Charged Polypeptides Determined by ATR-FTIR and AFM

Abstract We report on factors influencing the orientation of polyelectrolyte multilayers (PEM) containing charged polypeptides. As factors, the presence and absence of mechanical unidirectional texturization, the conformation, and the molecular weight will be outlined in four typical samples. For that, the charged cationic homopolypeptide poly(L-lysine) (PLL) was used, whose conformations can be changed from random coil to α-helix by salt type or pH value. PEM of PLL and poly(vinylsulfate) (PVS) were prepared by consecutive adsorption. Dichroic in situ attenuated total reflection infrared (ATR-IR) spectroscopy and atomic force microscopy (AFM) were used for orientation and surface topology characterization, respectively. Untexturized surfaces, the random coil conformation, and low molecular weight of PLL caused the formation of isotropically structured PEM films, and the α-helical conformation and the high molecular weight of PLL resulted in anisotropic PEM films. Polypeptide-containing PEM could be used as biomimetic coatings for specific interaction with α-helical proteins.
Aotearoa New Zealand social workers and their views of inclusion of animals in social work practice – A descriptive study

PURPOSE: Given the benefits of the human–animal bond (HAB), animals are being used in a range of social work settings. It is important to gain a more in-depth understanding of social work practitioners’ knowledge and actions in these interactions. The purpose of this study was to examine the views and knowledge of social workers in relation to the HAB in Aotearoa New Zealand. METHODS: A survey using an online portal was administrated to qualified social workers via professional and community networks to assess their exposure, level of knowledge, support, training, and barriers to animal–human relations. RESULTS: A total of 140 questionnaires were used for analysis. The results, similar to findings from Canada and the United States, indicate that social workers seemed to have high exposure to information about the benefits of HAB and understanding of the connections between animal abuse and child abuse/domestic violence. Only 68% have included animals in their social work practice. The vast majority have had no specific training in HAB. Untested or untrained animals were also reported to have been used in social work intervention practice. The lack of clear workplace policies, support and professional training in HAB were key barriers that inhibited the inclusion of animals in practice. CONCLUSIONS: Lack of understanding over how to include HAB in practice has serious implications for social work. HAB continues to influence and contribute to the lives of families and individuals and social workers have a duty to develop general awareness and knowledge of the benefits to human health and wellbeing of interacting with animals.

Shadows and shields: Stars limit their collaborators’ exposure to attributions of both credit and blame

Building on the notion of cumulative advantage, we under-take a nuanced examination of how collaborating with a star affects attributions of credit and blame to nonstars in collaborative endeavors. Situating our inquiry in the US hedge fund industry, we hypothesize two-way interactions predicting that collaboration with a star comanager will weaken both the positive effect of comanaged fund success and the negative effect of comanaged fund failure on nonstar managers’ professional status attainment (i.e., the status of a manager’s subsequent employing firm). Specifically, we argue that the involvement of a star comanager will weaken prospective employers’ attributions for positive or negative performance to a focal nonstar manager, due to presumptions of the star’s disproportionate influence in collaborative decisions. We then theorize a series of three-way interactions specifying the roles of other signals of a nonstar manager’s competence in this process. More precisely, we argue that a nonstar’s performance outside the collaborative context and the status of the nonstar’s current employer will weaken the dampening effect of comanaging with a star in the context of success and strengthen the favorable, blame-reducing
GRAVIMETRIC DETERMINATION OF AIRBORNE DUST BY USING A FILTER CARTRIDGE INSIDE A CLOSED-FACE, 37-MM POLYSTYRENE CASSETTE

The current practice for the determination of personal exposures to airborne dusts involves the aspiration of known quantities of air through membrane filters held in filter holders. The two-piece, 37-mm polystyrene cassette is the most typically used filter holder. Two potential major errors exist with filter-based air-sampling methods. The first error is caused by potential sample loss on the inside of the cassette top during the sample's collection and shipment back to the laboratory for analysis. A second error is caused by sample loss during the removal of the filter from the cassette prior to analysis. The potential for sample loss creates a third problem that is specific to gravimetric methods. A small linear range exists for gravimetric methods between their limit of quantitation and filter capacity. A new filter cartridge device was developed and evaluated to estimate the concentration of airborne total dusts over a larger linear range while eliminating negative bias errors associated with both s.
Improving productivity of maize-lentil rotation in alkaline Fluvisol following soil test crop response (STCR) - targeted yield approach of nutrient management

ABSTRACT Soil-test crop response (STCR) approach is aiming to precise adjustment of fertilizers under varying soil-test values for targeted-yield, presently gaining recognitions for sustainable nutrient management. The study aimed to envisage the precision scale of STCR targeted-yield models in maize-lentil rotation in alkaline Fluvisol under sole-fertilizer and integrated nutrient management (with farmyard manure). Fertility-gradient, test-crop diagnostic, and validation trials were conducted following STCR technical program. Soil fertility gradient and variable fertilizer doses had caused a large variation in grain yield of maize (0.99–4.94 t ha−1, CV = 30%) and lentil (1.11–2.02 t ha−1, CV = 13%). Lentil had increased potential to utilize soil nutrient pools; in contrast, maize was highly responsive to fertlizer nutrients. Multivariate-regression analysis revealed that fertilizers N, P, and S had a strong and direct influence on maize yield; where fertilizer-P was the primary yield-determining variable for lentil. Both sole-fertilizer and integrated STCR-based treatments attained the targeted-yields in maize. However, STCR treatments could not attain the targeted-yields in lentil (17–29% deviation), but had yield advantage over the blanket recommended fertilizer dose. Hence, in tropical-alkaline soils, integrated STCR targeted-yield approach could be the sustainable nutrient management option(s) for improving the productivity of the maize-lentil system.
Hybrid Additive Manufacturing of Collector Coins

The objective of this paper is to present a new hybrid additive manufacturing route for fabricating collector coins with complex, intricate contoured holes. The new manufacturing route combines metal deposition by additive manufacturing with metal cutting and forming, and its application is illustrated with an example consisting of a prototype coin made from stainless steel AISI 316L. Experimentation and finite element analysis of the coin minting operation with the in-house computer program i-form show that the blanks produced by additive manufacturing and metal cutting can withstand the high compressive pressures that are attained during the embossing and impressing of lettering and other reliefs on the coin surfaces. The presentation allows concluding that hybrid additive manufacturing opens the way to the production of innovative collector coins with geometric features that are radically different from those that are currently available in the market.
Adolescent Pregnancy and Outcomes: A Hospital-Based Comparative Study at a Tertiary Care Unit in Eastern Province, Sri Lanka

Background Adolescent pregnancy is a high-risk condition that can potentially lead to adverse perinatal and obstetric outcomes. It is a growing concern in developing countries including Sri Lanka. The main objective of this study was to evaluate obstetric and perinatal outcomes amongst adolescent pregnancies and compare them with outcomes of pregnancies of average maternal age (AMA) women. Method This was a prospective, cross-sectional study conducted at a tertiary care hospital in the Eastern province of Sri Lanka. A total of 795 primigravidae who had singleton pregnancies and delivered their live babies over a period of three months from February to April 2019 were selected for the study. The data were retrieved from Bed Head Tickets (BHTs) of those patients upon discharge from the postnatal ward. Results The majority of primigravida was AMA women and accounted for 83.4% (n=663) of the study population while primiparous adolescents comprised 16.6% (n=132). Among the 132 adolescent pregnancies, 81.1% (n=107) were associated with complications and the remaining 18.9% (n=25) were uncomplicated. The most common risk associated with adolescent pregnancy was the low birth weight (LBW; n=24, 18.2%), followed by preterm labour (n=10, 7.6%). An adolescent mother had a 1.3 times higher possibility of delivering an LBW baby than an AMA mother and the risk was statistically significant (p=0.04). The likelihood of delivering an intrauterine growth restriction (IUGR) baby was higher in adolescent mothers (6%) than in AMA mothers (5%). Adolescent mothers had a 1.2 times higher chance of delivering newborns with IUGR compared to AMA mothers; however, the difference of IUGR was not statistically significant (p>0.05). The incidence of foetal distress was less among adolescent mothers compared to AMA mothers. The majority of the babies (n=126, 95.5%) of adolescent pregnancies were healthy. Only 4.5% (n=6) babies needed neonatal intensive care unit (NICU) admissions; of those, four babies had very LBW and prematurity and the other two babies depressed at birth and developed respiratory distress. Conclusion Adolescent pregnancy carries a significant risk of obstetric complications including LBW and prematurity that should draw public and healthcare providers’ attention. The effectiveness of a comprehensive antenatal and community-based program to prevent adolescent pregnancy and related adverse outcomes should further be evaluated.
Osmotic adjustment in indoor grown cassava in response to water stress

The water content-water potential relation in stressed and unstressed cassava (Man-ihot species) was examined to ascertain (i) the magnitude of osmotic adjustment in response to water stress and (ii) the mechanisms of such adjustments. Water stress resulted in a displacement of the water content-potential relation such that at any leaf water potential the water content was higher in the stressed plants. The osmotic potentials of turgid leaves (100% relative water content) were -0.97 and -1.00 MPa in the unstressed cultivars CMC 9 and MCOL 113 respectively. In the stressed plants, the values were-1.13 MPa (CMC 9) and-1.14 MPa (MCOL 113). The 0.14 to 0.16 MPa osmotic potential difference between the stressed and unstressed plants suggests that a stress-induced osmotic adjustment occurred in both cultivars. The biiSk volumetric elastic moduli at turgor pressures above 0.10 MPa were 9.84 MPa (CMC 9) and 13.58 MPa (MCOL 113) in the unstressed plants. Tbe higher values found in the stressed plants, 14.56 MPa in CMC 9 and 16.91 MPa in MCOL 113, suggest a stress-induced decrease in cell wall elasticity. Hence, the observed shift in the wafer content-potential relations in the cassava involved both an osmotic adjustment and a decrease in cell wall elasticity. Increasing the number of stress cycles per plant did not cause a further displacement of the water content-potential curves.
