Non-Injection and Low-Temperature Approach to Colloidal Photoluminescent PbS Nanocrystals with Narrow Bandwidth

Colloidal photoluminescent (PL) PbS nanocrystals have attracted a lot of attention in various applications such as bioimaging and optical telecommunications due to their tunable bandgap in the near-infrared region of the electromagnetic spectrum. Hot-injection processes seem to be the best to engineer high-quality PbS nanocrystals. However, there is a limited body of literature documented on the syntheses, with little information on synthetic parameters affecting the optical properties of the product. Moreover, small PbS nanocrystals with large bandgap greater than 1.38 eV (ca. 900 nm) and narrow bandwidth are rarely reported, due to the fact that high-temperature growth in hot-injection processes leads to large nanocrystals rapidly. This manuscript deals with our noninjection and low temperature approach to small PbS nanocrystal ensembles with bandgap in wavelength shorter than 900 nm and with narrow bandwidth; the growth temperature can be as low as room temperature. For our noninjection approach, syste.
Ozone Oxidation of Endocrine Disruptors and Pharmaceuticals in Surface Water and Wastewater

The oxidative removal of a diverse group of trace organic contaminants from surface water and wastewater was evaluated using ozone (O3) and O3 combined with hydrogen peroxide (O3/H2O2). Target compounds included estrogenic and androgenic steroids, pharmaceuticals, pesticides, and industrial chemicals. Bench- and pilot- scale experiments were conducted with surface water spiked with the target compounds and wastewater effluent containing ambient concentrations of target compounds. Full-scale water treatment plants were sampled before and after ozonation to determine if bench- and pilot-scale results accurately predict full-scale removal. In both drinking water and wastewater experiments, the majority of target compounds were removed by greater than 90% at O3 exposures commonly used for disinfection. Atrazine, iopromide, meprobamate, and tris-chloroethylphosphate (TCEP) were the most recalcitrant compounds to oxidize using O3, with removals generally less than 50%. The addition of H2O2 for advanced oxidation was of little benefit for contaminant removal as compared to O3 alone. O3/H2O2 provided a marginal increase in the removal of dilantin, diazepam, DEET, iopromide, and meprobamate, while decreasing the removal efficacy of pentoxifylline, caffeine, testosterone, progesterone, and androstenedione. In wastewater experiments, O3 and O3/H2O2 were shown to remove in vitro estrogenicity. Collectively, these data provide evidence that O3 is a highly effective oxidant for removing the majority of trace organic contaminants from water.
Cretaceous Record from a Mariana– to an Andean–Type Margin in the Central Cordillera of the Colombian Andes

The Cretaceous tectonic evolution of the western margin of South America involves a shift from an extensional convergent margin toward a more compressional setting that marks the beginning of the Andean Orogeny. In the Colombian Andes, this changing scenario is recorded in the Cretaceous sedimentary and magmatic rocks of the Central Cordillera. A review of field relationships, together with analysis of integrated provenance constraints, including sandstone petrography and detrital zircon geochronology from various localities, suggests that during the Early Cretaceous until the Aptian – Albian, siliciclastic basin fills were characterized by transgressive fining– upward trends, with prominent first–cycle quartzose provenances that indicate strong chemical weathering in the source areas.

SODIUM THIOSULPHATE SHOWS PROMISING ANTI-INFLAMMATORY ROLE AGAINST DOXORUBICIN-INDUCED RENAL INJURY DEPENDING ON TLR4 PATHWAY INHIBITION

Doxorubic in nephrotoxicity is always a major cause of death for cancer patients. objectives: our study aimed at proving the potential curative mechanisms of sodium thiosulphate, on experimentally-induced nephrotoxicity in rats by doxorubicin explaining the mechanisms of the serious inflammation pathway TLR4/MAPK P38/NF-κB/TNF-α. Methods: nephrotoxicity was induced by parenteral administration of doxorubicin (5.2mg/kg/ weekly for 4 weeks). And the treatment depends on giving sodium thiosulphate (400 mg/kg, p.o.) One hour before doxorubicin injection for4 weeks. Doxorubicin injection caused severerenal dysfunction evident from a significant increase in the kidney biomarkers; urea,creatinine, KIM.1, and serum cystatin C,together with decreasing serum albumin and total protein.Besides,increased MDA and MPOassociated with a significant decrease inGSH, Nrf-2,SOD and catalase activities, heightened inflammatory markers TLR4, MAPK P38,NF-κB,IL-1β, and TNFalpha also, induced apoptotic markers expression in renal tissues of doxorubicin group.However, treatment with sodium thiosulphate normalized oxidative markers, inflammatory markers,MDA,MPO, GSH, SOD, Nrf-2and catalase. Also, prevented apoptotic changesthroughsuppressing BAX and increasing Bcl-2. Conclusion: Our study provides a promising protective use of sodium thiosulphate against doxorubicin nephrotoxicity.
Male-male competition in ants (Hymenoptera: Formici dae)

Aspects of male mating behavior in ants have been l arge y ignored in research until recently. Mating i ants is usually a short episode at the beginning of their life, oft en in large, anonymous swarms; therefore it has bee n argued that the potential for male-male competition is limited. Des pite of this, several earlier studies on mating in ants described that males heavily compete for female sexuals, indicatin g pre-copulatory male competition. In the last few years, more and more studies investigating post-copulatory competit ion have been conducted, and they revealed fascinat ing examples of male traits to gain fertilization advantages ove r other males. Ant species exhibiting intranidal ma ting have been researched thoroughly, providing new insights also in t pre-copulatory conflicts. We review what is know n so far on malemale competition in ants. Further studies may uncov er additional unknown male competitive tactics and provide a better understanding of sexual selection in ant mal es, and we believe these studies offer an ideal sys tem to compare male competition in social and non-social insects.
Persistence, mobility and degradation of hexazinone in forest silt loam soils

Abstract This study reports the persistence, degradation, vertical leaching and lateral movement of hexazinone, 3‐cyclohexyl‐6‐(di‐methylamino)‐1‐methyl‐1,3,5‐triazine‐2,4(1H,3H)‐dione, in a white spruce plantation treated at 4.3 kg active ingredient (ai)/ha by a helicopter equipped with a MICROFOIL boom. Soils were monitored for 104 days after treatment for residues of hexazinone and its metabolites A, 3‐(4‐hydroxycyclohexyl)‐6‐(dimethylamino)‐1‐methyl‐1,3,5‐triazine‐2,4(1H,3H)‐dione and B, 3‐cyclohexyl‐6‐(methylamino) ‐1‐methyl‐1,3,5‐triazine‐2,4(1H,3H)‐dione. Soil at 3 depths, including a surface organic, and 0–15 cm and 15–30 cm mineral layers, were collected and analysed before and at 9, 23, 55, 104 days after application. Sixty six percent (66? ) of hexazinone was degraded and dissipated at the end of 104‐day monitoring, decreasing from 7.12 ug/g (9 days) to 2.09 ug/g (104 days). The higher amount of metabolite‐? (30–50? of hexazinone detected) compared to metabolite‐B (0–12? ) indicated higher hydrox.
Comprehending the Comprehensive Geriatric Assessment. Feasibility, outcomes and experiences of frail older people

Despite existing knowledge on how to approach frail people in health care, the care they receive is commonly not designed to meet their complex needs and support them in maintaining their activities of daily living. One way to support frail older people when needing health care could be to enable them to share their life-stories and communicate their wants and wishes. Learning about a person’s social history can be a key element in comprehending older people in their care needs. The overall aim of this thesis was to evaluate the Comprehensive Geriatric Assessment (CGA) for frail older people aged 75 or older and to explore their experiences of care following a CGA. Methods: A pilot study with 30 frail older people (>75 years) was performed to determine the feasibility of the CGA, the process and procedures, instruments and proof of principle. Participants were included to the CGA intervention group or the control group that received regular medical care. After the pilot was determined to be feasible, the full RCT was carried out with an additional 125 participants. The 155 participants were followed up at one and six months. During the RCT 10 participants from the CGA ward partook in additional qualitative interviews, which explored through narratives 1) what personal resources they had and how they experienced health care services using three dimensional-analysis, and 2) how they experienced receiving a CGA, using a conventional content analysis. Results: Identifying and screening frail older people who might benefit from a CGA was successful, and those receiving the intervention were met by staff practicing increased attention to safety, ADLs, assistive devices, and discharge planning (Study I). The participants to a high extent agreed that the CGA care met their needs (Study II). The CGA participants experienced having a voice when receiving health care services by using their personal resources (Study
The Impact of Research and Development (R&D) Intensity on Financial Performance and Firm Value: An Empirical Study on Pharmaceutical Companies Listed on Egyptian Stock Exchange

This paper examines the relation between Research and Development (R&D) intensity and both of the financial performance and firm value for pharmaceutical companies listed on Egyptian Stock Exchange. Because of the future benefits related to R&D, the researcher examines the relationship between R&D intensity and both of the current and future performance. R&D intensity is measured as the ratio of R&D expenditures to total revenues. The financial performance as a first dependent variable is measured using three accounting-based operating performance measures; Return on asset (ROA), Return on Equity (ROE), and return on sales (ROS). ROA is computed as the ratio of Earnings Before Interest and Tax (EBIT) to total assets; ROE is the ratio of Net income after tax to stockholder equity, and ROS is the ratio of Net income after tax to net sales. With regard to the second dependent variable, firm value, Tobin’s Q is used, which is measured by (market value of equity+ book value of liabilities) divided by book value of total assets. Using data of listed pharmaceutical companies on Egyptian stock market for the period between 2000 to 2019, empirical results showed a significant negative relationship between R&D intensity and current performance measured by ROE and ROS, in addition to Tobin’s Q. However, the results showed an insignificant negative relation with ROA. On the contrary, Findings indicated a significant positive relationship between R&D intensity and future firm performance measured by ROA only and Tobin’s Q, and an insignificant positive relation with ROE and ROS.
High faecal carriage of multi-drug resistant Enterobacteriaceae and other gram negative strains among food handlers in Cosmopolitan Cities of The Gambia

The introductions of advanced antibiotics have triggered complex versions of resistant genes in gram-negative bacteria. In a generation witness limited discovery of antibiotics makes this phenomenon a major public health threat. This study aims to establish the fecal carriage rate of multidrug-resistant Enterobacteriaceae strains among food handlers. Data was extracted from a prospective cross-sectional study – ‘Prevalence and risk factors of fecal carriage of Extended Spectrum β-Lactamase producing Enterobacteriaceae amongst food handlers in Lower Basic Schools in West Coast region of The Gambia. The study enrolled 600 randomly selected food handlers (565 of which had complete data set) from 60 lower basic schools in 7 districts in the West Coast Region of The Gambia. Stool samples were collected from the participants and screened for resistance to cefotaxim. Isolated organisms were further tested for susceptibility to cephalosporins, carbapenems, fluoroquinolones and other families of antimicrobials as per Clinical Standard Laboratory Institute guidelines. The association of risk factors to fecal carriage of resistant Enterobacteriacea was performed using Pearson Chi squared and fishers exact (P
The Role of Adjuvant Vinpocetine Therapy in Aspirin-Treated Cerebrovascular Patients

BACKGROUND: The aim of our pilot study was to investigate the endothel dysfunction, hemorheological and agonist-induced platelet aggregation changes in aspirin-treated cerebrovascular patients after parenteral vinpocetine admission (VP). METHODS: Hemorheological parameters (hematocrit, plasma fibrinogen, whole blood viscosity, red blood cell aggregation and deformability), endothel dysfunction markers (von Willebrand factor, soluble P-selectin) and agonist-induced (collagen, epineprine, arachidonic acid and adenosine-diphosphate) platelet aggregation values were evaluated at baseline, 7th and 30th day. RESULTS: Parenteral vinpocetine infusion significantly decreased von Willebrand factor levels and arachidonic acid-induced platelet aggregation values and they still remained significant after 30 days. Red blood cell deformability was significantly decreased after a month. No statistical differences among the other examined hemorheological parameters could be found. CONCLUSION: Vinpocetine, partially by its benefitial hemorheological and endothel-dysfunction improving profile may help to overcome aspirin resistance.
Transitions in loneliness in later life: the role of social comparisons and coping strategies

Abstract This study explored the coping strategies and social comparisons used by older adults on different loneliness trajectories (decreased loneliness, stable loneliness and degenerating loneliness). The adaptive consequences of social comparison in later life are recognised as an important strategy for preserving life satisfaction regardless of age-related losses. Coping strategies are also important in managing loneliness. Narrative interviews were conducted with lonely older adults (N = 11) who had participated in Wave One of the Maintaining Function and Well-being in Later Life Study Wales (CFAS Wales). The study found key differences in the coping strategies employed by older adults on different loneliness trajectories. Differences in coping styles between those who reported decreased loneliness and those who were chronically lonely stemmed from perceptions as to whether loneliness was modifiable or not. Different types of social comparison were also found to modulate the loneliness experience. The findings indicate that higher-order strategies (problem, emotional and meaning focused) are not distinct entities but are part of a dynamic process. The management of loneliness in later life may be dependent on several factors, including older adults’ interpretations of the cause of loneliness. These interpretations will have implications for interventions aimed at alleviating chronic loneliness, where the focus may have to be on changing older adult's perceptions of unmodifiable loneliness.
Bitumen Solubility Model Using Hansen Solubility Parameter

The Hansen solubility parameter (HSP) for bitumen was determined using solubility data of bitumen in a set of 48 solvents with known solubility parameters. A computer program was used to calculate the best estimate of the solubility parameter of Venezuelan bitumen as well as a pseudo sphere around the HSP. The program also permitted plotting of the spheres in a 3D diagram. The solubility parameter of the asphaltenes and maltenes was determined and compared to the HSP of the bitumen. It was found that the asphaltenes may be dissolved in the maltenes rather than dispersed, indicating that no asphaltene micelles can exist. The HSP of bitumen was also compared with HSP of three different polymers to demonstrate how to predict the compatibility of polymers with bitumen. The HSP of one crude oil from the North Sea was also determined. The determination of the Hansen Solubility Sphere is proposed as a method to estimate internal stability of bitumen, crude oils, and residues as well as compatibility with added m.
Non-Prescription Antibiotic Use for Cough Among Chinese Children Aged Under 5 Years: A Community-Based Cross-Sectional Study

Background: Cough is a common symptom in childhood and is an important circumstance of inappropriate antibiotic use. This study aimed to investigate the non-prescription use of antibiotics for cough among children aged under 5 years.Methods: We conducted a community-based survey of under-5 children in Yiwu, China from October to November 2019. The subjects were enrolled from 14 townships using a two-stage stratified sampling procedure. Detailed information was collected through a face-to-face interview based on a standard questionnaire, and the children’s caregivers answered as agents. Univariable and multivariable logistic regression analyses were performed to explore the factors associated with nonprescription use of antibiotics for cough in children. Results: A total of 3102 children were included in the study, and 1211 children were reported to have a cough in the past month. Among them, 40.2% (487/1211) were medicated with antibiotics, and 18.7% (91/487) of these were unprescribed. Cephalosporins were the most frequently used antibiotic (52.8%), and community pharmacies were the main source (53.7%). Children who coughed for 1–2 weeks (OR=1.73, 95% CI=1.03-2.90) or 3–4 weeks (OR=2.39, 95%CI=1.08-4.97), with 2 or more accompanying symptoms (OR=2.44, 95% CI=1.14-5.72), or with a family annual income between 50000 and 100000 RMB (OR=4.14, 95% CI=1.41-17.69) had a higher risk of non-prescription use of antibiotics than those coughing for <1 week, without accompanying symptoms, or with family annual income <50000 RMB.Conclusions: Our findings indicated that a high proportion of infants and young children had been treated with antibiotics for cough, and nearly 1/5 of them were used without prescription. More public health campaigns and further health teaching on the appropriate use of antibiotics are needed to ensure the rational treatment of cough in children.
Parametric study on dispersed phase holdup and axial drop size distribution in a pulsed disc and doughnut extraction column

ABSTRACT A parametric study of the dispersed phase holdup, specific power consumption (P) and axial drop size distribution (ADSD) in a pulsed disc and doughnut column have been carried out with 30% Tri-Butyl Phosphate- 0.01 M nitric acid system. ‘P’ and holdup decreases with increasing percentage duty cycle and increases exponentially with increased pulsation. Whereas ‘P’ remains almost independent of total superficial velocity and phase flow ratio. At the top of the extraction section, the most uniform DSD have been observed. Subsequently, Unified empirical correlations have been developed over much wider range for predicting the holdup and Sauter mean diameter.
The perspective of national ERP vendors in achieving ERP project success in government organisations: a case of Saudi Arabia

ABSTRACT This paper aims to explore Key Influencing Factors (KIFs) from the perspective of national ERP vendors throughout pre-implementation and during implementation of ERP projects. We conducted a mixed methods study on 10 national ERP vendors involved in government sector projects in Saudi Arabia. KIFs were identified through in-depth interviews and prioritised using a multi-criteria decision analysis method. Findings suggested a list of KIFs that are grouped into four main categories namely sponsors and leadership, IT capabilities, change management and project management. The prioritisation of the KIFs reveals the ERP capabilities and the stakeholder managers to be the most important factors.
PENAMPILAN REPRODUKSI SAPI BALI PADA SISTEM PEMELIHARAAN SEMI INTENSIF

Bali cattle is one of the native cattle in Indonesia. High fertility and are capabled to adapt well in tropical environment is one of the superiority of bali cattle. Bali cattle farming in East Nusa Tenggara (NTT) are generally managed by intensive, semi-intensive and extensive system traditionaly, without any recording and lacking good breeding practices. The purpose of this research is to determine the reproduction performance of bali cattle on semi-intensive management system based on pregnancy rate, days open and calving interval. The number of cattles used in this study were 40 cows on age 4-7 years. The methods used were interviews and rectal palpation to know the reproductive status of livestock. Descriptive analysis was used in this research. The results showed that the pregnancy rate was 45%, days open was 112,5 days and calving interval was 13,075 months. This study indicated a decreased reproductive efficiency of bali cattle in Kupang Regency, hence an improvement of the management reproduction is required to achieve good reproductive management.
Assessment of Exclusive Breastfeeding Among Working Mothers in Tertiary Institutions (A Case Study of Imo State)

Globally, the practice of exclusive breastfeeding has been recognized as an important public health strategy for reducing infant and child morbidity and mortality. While studies have shown that many newborns in Nigeria are still fed with something other than breast milk despite the numerous health benefits of exclusive breastfeeding, there is little information on why the practice of exclusive breastfeeding is low among the educated. This study therefore assessed the practices of exclusive breastfeeding among working mothers in tertiary institutions in Imo State. Mixed research design and multi-stage sampling method were used for this study. For the quantitative data, 912 copies of questionnaire were administered and analyzed using descriptive and inferential statistics while 20 in-depth interviews were conducted for the qualitative data and analyzed using content analysis method. It was found that spouse educational level is positively correlated with practice of exclusive breastfeeding. Short duration of maternity leave and inconvenient working environment were major factors that undermine exclusive breastfeeding practice among working mothers. In conclusion, while exclusive breastfeeding awareness is high, many working mothers do not practice it. Consequently, employers should increase paid maternity leave to minimum of six months and make work environment to be conducive for breastfeeding mothers and their babies.
