Knowledge, Attitudes, Practices and Blood Pressure Control of Hypertensive Patients at a South African Primary Health Care Centre

Hypertension is a serious global and South African public health problem. The high prevalence of uncontrolled hypertension is related to a patient’s lack of knowledge and healthy practices. The study aimed to assess the knowledge, attitudes and practices of hypertensive patients and their blood pressure control at a rural community health centre. This was a prospective cross-sectional study conducted on diagnosed cases of hypertension at the centre. Binary logistic regression analysis was conducted to determine the factors for the control of hypertension. Two hundred and ninety-seven known hypertensive patients were recruited, the majority of which were female. Eighty-eight percent were older than 45 years, and almost all had a monthly income of less than R3000 (USD 190). More than half controlled their blood pressure. It was found that 46% had poor knowledge, 64% had good attitudes and 60% were practising positively regarding the control of hypertension. Hypertensive patients attending the centre had poor knowledge but good attitudes and practices towards hypertension. The study revealed an urgent need for improved health promotion and educational efforts to increase the knowledge of hypertension in rural communities and to address poverty as a major obstacle to healthy lifestyle choices.

: The composition and loads of organochlorine pesticides (DDTs, HCBs, HCHs, CHLs) and polychlorinated biphenyls (PCBs) transported with the Vistula River waters to the Gulf of Gdansk in 1991-1992 has been determined. The method of organochlorine compounds measurement was capillary gas chromatography with ECD after adsorption of the analyte on Ambertlite XAD-2, resin and subsequent elution, clean-up and HPLC fraction of the extract. The concentrations of DDTs, HCBs, HCHs, CHLs and PCBs in the Vistula River water ranged between 120-840, 7.6-52, 1600-410,000, 8.1-57 and 120-300 pg/l, respectively. During 12 months period of the study the total load of DDTs, HCBz, HCHs, CHLs and PCBs transported with the Vistula River water to the Gulf of Gdansk was assessed on 10.54, 0.73, 1377, 0.38 and 5.02 kg, respectively.
Effect of Chemical Treatment on the Durability Behavior of Coir Geotextiles

ABSTRACT The paper presents the effect of chemical treatment on the durability study of untreated/treated woven/non-woven coir geotextile. The p-aminophenol, sodium periodate, and sodium hydroxide were used for the treatment of the coir geotextiles. For this, laboratory wide width tensile strength test was conducted in a universal testing machine for untreated/treated woven/non-woven coir geotextile placed at the interface of sand-overlaying clay after the period of 2, 6, 8, 12 months, respectively. The results of this study reveal that the tensile strength decreased for the untreated and treated woven coir geotextiles with increase in the period. The reduction in the tensile strength for the woven coir geotextiles was more in the weft direction as compared to the warp direction. The reduction in the tensile strength of the treated woven coir geotextiles was more as compared to the untreated coir geotextiles. The reduction in the tensile strength for the non-woven coir geotextiles was more in the weft direction as compared to the warp direction. The reduction in the tensile strength for the untreated non-woven coir geotextile was more as compared to the treated non-woven coir geotextiles.
A Country-of-Origin Perspective on Climate Change Actions: Evidence from France, Morocco, and the United States

Country-of-origin (COO) research cites the influence of country-level actions on consumers’ attitudes but does not specify how such actions might influence the COO image, particularly in a climate change context. However, various countries adopt different climate change actions, with notable potential implications for products associated with the nations’ images; therefore, it is vital to understand the relationship between climate change actions and consumers’ attitudes toward their country. This study, which solicits responses from 1,389 consumers in France, Morocco, and the United States, investigates whether and how climate change actions influence each COO image and consumers’ attitudes toward it, which vary with consumers’ level of climate change concern. Such climate change actions also exert distinct effects that are moderated by the cultural context. Therefore, this study extends the COO literature to a climate change context and provides relevant implications for policy makers and marketing managers aiming to improve their COO image.
Recent advances in immunotherapy for pancreatic cancer

Pancreatic ductal adenocarcinoma (PDAC) remains a disease with a dismal prognosis. Since 1996 there have only been two upfront regimens found to be superior to gemcitabine: FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan and oxaliplatin), and gemcitabine plus nab-paclitaxel. Despite the improvement noted in these trials, PDAC is highly chemo-resistant and patients who respond will inevitably develop resistance. The unique immunosuppressive tumor microenvironment with extensive desmoplasia has posed challenges to developing new and effective treatments. Therapeutic vaccines, combination treatments, adoptive T cell transfer, as well as immunomodulators are being explored. With the emerging use of immunotherapy and immunomodulators, the scope of this review is to present the current data on these agents as well as focus on the advancements in the treatment of PDAC. Overall, results in this realm have been disappointing to date reflecting the non-immunogenic and complex tumor microenvironment of PDAC.

Conclusion: Musical and photographic stimuli had a positive effect on the cognitive level, daily life activities and autobiographical memory in seniors with Alzheimer’s disease.
Influence of rubber pads on vibration levels and structural behavior of subway tunnels

The principal aim of this paper is to analyze the impact of rubber pad systems on levels of vibrations and values of stresses and deformations induced in the subway tunnel segments. Thus, the 3D model has been selected to be isotropically simulated in the ANSYS program to conduct a finite element analysis. Therefore, the proposed track system in the tunnel of line 4 of the Greater Cairo Metro has been selected as an analytical and simulation case study. The impact of using eight different values for the stiffness of the rubber pad system in the case of a single tunnel has been analyzed. The results showed that levels of vibrations are significantly affected and are in logarithmic correlation with the stiffness. Also, the impact of the stiffness on the deformations and stresses are determined as well as mathematical models connecting the different parameters have been introduced.
Reconstruction of Miocene to Pleistocene sea‐surface conditions in the eastern Indian Ocean on the basis of calcareous nannofossil assemblages from ODP Hole 757B

We studied the calcareous nannofossil assemblages from Ocean Drilling Program Hole 757B in the eastern Indian Ocean to reconstruct the sea‐surface conditions, especially changes in thermocline/nutricline depth, from the middle Miocene to the Pleistocene. Nutrient levels at the sea surface were reconstructed from the nannofossil accumulation rate, abundance of Discoaster, and coccolith size variations in Reticulofenestra. The sea‐surface conditions were likely to have been oligotrophic with a deep thermocline/nutricline during 11.8–7.5 and 6.7–6.2 Ma. The change from oligotrophic to eutrophic conditions at 7.5–6.7 Ma was caused by an influx of nutrient‐rich terrestrial material or upwelling of nutrient‐rich water induced by intensified southeast trade winds. This conclusion is supported by a marked increase in the magnetic susceptibility of the sediment that is coincident with the change from oligotrophic to eutrophic assemblages. The diminished abundance of Discoaster after ~ 3.0 Ma indicates shallowing of the thermocline/nutricline after that time, which confirms the reduced Indonesian Throughflow resulting from tectonic restriction and intensified cooling of the Benguela upwelling system. Decreases in the modal coccolith size of Reticulofenestra, indicating eutrophic conditions, are observed in three horizons. Two of these events (at 7.5 and 5.0 Ma) correspond to biogenic blooms in the Indian Ocean at 7.6 Ma and 6.0–5.0 Ma, respectively.
Teachers as researchers: Reflecting on the challenges of research–practice partnerships between school and university in Chile

Teachers have tended to be underestimated as experts of their own practice and relegated to a technical role. In this context, action research appears as a form to legitimate teachers as active agents and producers of educational knowledge. This article aims to examine how a collaborative research–practice partnership between schools and universities in Chile fosters teachers’ role as researchers. It adopts a qualitative methodology based on thematic analysis of data collected from questionnaires and focus groups. In particular, it reports perceptions of in-service teacher researchers who conducted research projects between 2016 and 2017 as a part of a researcher–practitioner partnership strategy implemented by a university in Chile. The findings suggest that the partnerships were highly valued among teachers because the partnerships allowed them to develop pedagogical reflection towards the improvement of their practices and required particular awareness and recognition of roles and the relationships between practical and theoretical knowledge. Finally, possibilities for strengthening teachers’ role as researchers and collaborative research are presented at the end of the article.
Asymbiotic Germination and Seedling Development of Terrestrial Orchid Bletilla striata Using in vitro and ex vitro Cultures

Procedures for asymbiotic germination and seedling development under in vitro and ex vitro conditions were investigated for Bletilla striata . Five different asymbiotic germination media (½ P6668 ¬Phytamax Orchid Maintenance Media, ½ P6668 ¬Phytamax Orchid Maintenance Media with coconut water, P723 Phyto Technology Orchid Seed Sowing Media, P723 Phyto Technology Orchid Seed Sowing Media with coconut water, and ½ MS media) for in vitro culture and sphagnum moss for ex vitro culture were examined for their effectiveness for 8 weeks on seed germination and seedling development of B. striata . Germination occurred in all media, however, the best germination rate was obtained in P723 medium with coconut water while the lowest frequency was obtained in sphagnum moss. Moreover, the highest leaf parameters of the seedlings of B. striata developed in ½ MS medium when the seedlings in sphagnum moss showed the lowest results. Furthermore, all germinated protocorms showed rhizoid formation in all media.
Controlling the channel diameter of the mesoporous molecular sieve MCM-41

We describe a simple method of controlling the channel diameter of the mesoporous molecular sieve MCM-41 in the 26.1–36.5 A range and the wall thickness in the 13.4–26.8 A range while using the same gel mixture. This is achieved by varying the synthesis temperature in the 70–200°C range and/or reaction times in the 0.5–96 h range. The unit cell parameter, channel diameter, thickness of the channel wall, surface area, degree of polymerization and grain morphology were monitored by X-ray diffraction, N 2 adsorption, 29 Si magic-angle-spinning NMR and transmission electron microscopy. MCM-41 with wider and thicker-walled channels and higher degree of polymerization is prepared at higher temperatures and at longer reaction times. Thick-wall MCM-41 has higher thermal stability but lower surface area. The material with the thickest channel wall ever reported (26.8 A) can withstand calcination at nearly 1000°C with little structural damage. We suggest a mechanism for the increase of wall thickness and channel diameter. Fascinating morphological features involving sealed silicate ‘tubes’ and ‘vesicles’ up to 1200 A in diameter are observed.
Dimensional Comparison Theory: Minimal Intervention Affects Strength of Dimensional Comparison Effects

Abstract Dimensional comparisons between math and verbal achievements affect students’ academic self-concepts by increasing (decreasing) students’ self-concept in the subject with their intraindividual higher (lower) achievement. Dimensional comparison theory assumes that dimensional comparisons are also triggered by external influences. The present research aimed to test this assumption by examining whether a minimal intervention, asking students to think more or less intensively about their subject-specific abilities, would affect the strength of dimensional comparison effects. In two experimental studies, N = 415 (Study 1) and N = 204 (Study 2) students from Germany rated their self-concepts in the subjects math and German after they had written down three thoughts about their math abilities and one or five thoughts about their German abilities (Study 1) or after they had written down three thoughts about their German abilities and one or five thoughts about their math abilities (Study 2). As expected, multiple group comparisons showed in particular a stronger negative dimensional comparison effect of students’ German (math) achievement on their math (German) self-concept after students had written down five thoughts instead of one thought about their German (math) abilities. This finding suggests that, as predicted in dimensional comparison theory, external influences can trigger dimensional comparisons.
New Technologies, Productivity, and Jobs: The (Heterogeneous) Effects of Electrification on US Manufacturing

We use city-industry data from 1890 to 1940 to identify the impact of electricity on manufacturing. We exploit cross-industry variation in pre-electricity energy intensity combined with geographic variation in proximity to early hydroelectric power plants. Labor productivity gains from the arrival of electricity were rapid and long-lasting. Electricity was labor-saving, induced capital deepening, and a hollowing out of the labor skills distribution. We document significant heterogeneity in electricity's effects: in sector-county pairs where the average firm was initially large, we find no significant expansion in employment, while in markets with relatively small firms, output and employment increased.
Cause Analysis of Hindering On-Site Lean Construction for Prefabricated Buildings and Corresponding Organizational Capability Evaluation

As prefabricated buildings play a significant role in the global fight against the new coronavirus “COVID-19,” they attract more global attention than other types of buildings. Lean construction helps to improve the benefits of enterprises and the working environment of workers. However, prefabricated buildings are encountering various challenges in implementing on-site lean construction. According to a cause-and-effect relationship, it will be more meaningful to explore the critical causes hindering on-site lean construction, namely, the critical barriers. Hence, this paper establishes a research methodology framework based on multimethod collaboration, including the exploratory factor analysis model regarding critical barriers, the exploratory factor evaluation model regarding organizational capabilities, and the important findings and suggestions. Thirty-one critical barriers of on-site lean construction for prefabricated buildings are identified via literature analysis, field survey, and semistructured interview. After pre-exploratory factor analysis, thirty critical barriers are finally retained and prioritized, and six common components are extracted and nominated. A large-scale project using the Engineering, Procurement, and Construction (EPC) mode is selected as a case study to evaluate its construction organizational capability to deal with the six common components. The important findings indicate that the inadequate professional management capability of managers is the most critical barrier, and the construction organization from the project case is fully capable of dealing with the common components during on-site lean construction. Six corresponding substantive suggestions are also proposed according to domain experts, and the most prioritized one of them is that an internal training or external recruitment is suggested to solve the inadequate professional management capability of managers. The internal training should take the form of seminars and training courses that invite senior prefabricated project management experts to participate. The external recruitment needs to focus on the management experience, lean skills, and leadership of managers in prefabricated projects. The established methodology framework proposes a new idea for the barrier analysis and corresponding organizational capability evaluation of on-site lean construction from the perspective of the specific prefabricated construction industry rather than the entire construction industry. Due to the special construction mode of prefabricated buildings, it further expands the current boundary of lean construction methodology. The findings and suggestions will provide a valuable reference and guidance for the prefabricated construction industry to solve the barriers regarding on-site lean construction.
Using an ensemble of artificial neural networks to convert snow
depth to snow water equivalent over Canada

Abstract. Canada's water cycle is driven mainly by snowmelt. Snow water equivalent (SWE) is the snow-related variable that is most commonly used in hydrology, as it expresses the total quantity of water (solid and liquid) stored in the snowpack. Measurements of SWE are, however, expensive and not continuously accessible in real time. This motivates a search for alternative ways of estimating SWE from measurements that are more widely available and continuous over time. SWE can be calculated by multiplying snow depth with the bulk density of the snowpack. Regression models proposed in the literature first estimate snow density and then calculate SWE. More recently, a novel approach to this problem has been developed and is based on an ensemble of multilayer perceptrons (MLPs). Although this approach compared favourably with existing regression models, snow density values at the lower and higher ends of the range remained inaccurate. Here, we improve upon this recent method for determining SWE from snow depth. We show the general applicability of the method through the use of a large data set of 234 779 snow depth-density-SWE records from 2878 non-uniformly distributed sites across Canada. These data cover almost four decades of snowfall. First, it is shown that the direct estimation of SWE produces better results than the estimation of snow density followed by the calculation of SWE. Second, optimizing MLP parameters separately for each snow climate class further improves the accuracy of SWE estimates. A comparison with commonly used regression models reveals that the ensemble of MLPs proposed here leads to noticeably more accurate estimates of SWE. This study thus shows that delving deeper into artificial neural network theory helps improve SWE estimation and that using a greater number of MLP parameters could lead to even further improvements.
