Phosphate sludge: opportunities for use as a fertilizer in deficient.

Phosphate sludge (PS) is an industrial by-product produced in huge quantities by the phosphate beneficiation plants in Morocco. In order to valorize this by-product, it was examined for its potential use as a soil fertilizer. The physicochemical properties, elemental and mineral content, morphological structure, and component stability of raw PS were investigated. In addition, pathogenicity, phytotoxicity, and the capacity of PS to promote plant growth in deficient sandy soil have been studied. The obtained results showed that PS was characterized by low values of moisture (2.10%), electrical conductivity (EC) (0.77 mS/cm), and organic matter (OM) (0.61%), with a slightly alkaline pH (8.20). Nevertheless, this material carried interesting content of fertilizing elements such as phosphorus (P2O5) of 20.01%, calcium (CaO) of 39.72%, and magnesium (MgO) of 2.33%. Thus, PS did not present any pathogenic or phytotoxic risk with a high increase in tomato plant growth than the control of only soil. In conclusion, the results of this study could provide the primary practical guidance for the PS application in deficient soils characterized by sandy texture.

The power of parent attitudes: Examination of parent attitudes toward traditional and emerging technology

Mobile technology devices continue to develop and change, creating increased opportunity for use by children. However, parents remain wary of screen time and question the benefits of using these devices for teaching specific content (e.g., science, technology, engineering, and math—STEM). Parent attitudes can play a very powerful role in children's media use and these attitudes may be even more impactful with emerging or novel technologies. As such, this study used a nationally representative sample of US parents to further document what child, parent, and family-level variables predict preschool children's mobile media device use with a particular focus on parent attitudes. Additionally, this study is the first to examine parent attitudes toward the emerging technological feature of haptic technology as an additional medium for teaching young children STEM content. Results demonstrate that parent technology attitudes, their own mobile media use, and certain family-level variables are related to general child mobile media use as well as science and math media use. Findings are discussed in relation to previous research and future work on haptic technology use for young children.

New Multi-Walled carbon nanotube of industrial interest induce cell death in murine fibroblast cells

The search for new nanomaterials has brought to the multifactorial industry several opportunities for use and applications for existing materials. Carbon nanotubes (CNT), for example, present excellent properties which allow us to assume a series of applications, however there is concern in the industrial scope about possible adverse health effects related to constant exposure for inhalation or direct skin contact. Thus, using cell models is the fastest and safest way to assess the effects of a new material. The aim of this study was to investigate the cytotoxic profile in LA9 murine fibroblast lineage, of a new multi-walled carbon nanotube (MWCNT) that was functionalized with tetraethylenepentamine (TEPA) to obtain better physical-chemical characteristics for industrial use. The modifications presented in the CNT cause concern, as they can change its initial characteristics, making this nanomaterial harmful. HR-TEM, FE-SEM and zeta potential were used for the characterization. Cytotoxicity and cell proliferation tests, oxidative and nitrosative stress analyzes and inflammatory cytokine assay (TNF-α) were performed. The main findings demonstrated a reduction in cell viability, increased release of intracellular ROS, accompanied by an increase in TNF-α, indicating an important inflammatory profile. Confirmation of the data was performed by flow cytometry and ImageXpress with apoptosis/necrosis markers. These data provide initial evidence that OCNT-TEPA has a cytotoxic profile dependent on the concentration of LA9 fibroblasts, since there was an increase in free radicals, inflammation induction and cell death, suggesting that continuous exposure to this nanoparticle can cause damage to different tissues in the organism.

The impact of hydraulic retention time on the performance of two configurations of anaerobic pond for municipal sewage treatment

ABSTRACT Anaerobic ponds have the potential to contribute to low carbon wastewater treatment, however are currently restricted by long hydraulic residence time (HRT) which leads to large land requirements. A two-stage anaerobic pond (SAP) design was trialled against a single-stage control (CAP) over four HRTs down to 0.5 days, to determine the lowest HRT at which the ponds could operate effectively. No statistical differences were observed in particulate removal between the ponds over all four HRTs, suggesting solids loading is not a critical factor in AP design. Significantly higher biogas production rates were observed in the SAP than the CAP at 1.5 d and 1.0 d HRT, and microbial community profiling suggests the two-stage design may be facilitating spatial separation of the anaerobic digestion process along reactor length. Hydrogenotrophic methanogensis dominated over aceticlastic, with acetate oxidisation a likely degradation pathway. Experimental tracer studies were compared to CFD simulations, with the SAP showing greater hydraulic efficiency, and differences more pronounced at shorter HRTs. Greater flow recirculation between baffles was observed in CFD velocity profiles, demonstrating baffles can dissipate preferential flow patterns and increase effective pond volume, especially at high flow rates. The study demonstrates the potential of APs to be operated at shorter HRTs in psychrophilic conditions, presenting an opportunity for use as pre-treatments (in place of septic tanks) and primary treatment for full wastewater flows. Two-stage designs should be investigated to separate the stages of the anaerobic digestion process by creating preferential conditions along the pond length.

Challenges and opportunities for use of long-lasting insecticidal nets to prevent malaria during overnight travel in Uganda: a qualitative study

BackgroundTravel is a well-recognized risk factor for malaria. Within sub-Saharan Africa, travellers from areas of lower to higher transmission intensity are potentially at high risk of malaria. Long-lasting insecticidal nets (LLINs) are the primary tool for prevention of malaria, and their widespread use has contributed to substantial reductions in malaria burden. However, travellers often fail to use LLINs. To further explore the challenges and opportunities of using LLINs, travellers were interviewed in Uganda.MethodsIn August and September 2019, 20 participants attending outpatient clinics at Naguru General Hospital in Kampala with a history of travel out of Kampala within the previous 60 days were purposively selected. Data were collected through in-depth interviews and analysed thematically using NVivo 12.ResultsOf the 20 participants, 13 were male. Thirteen of the 20 participants tested positive for malaria by microscopy, and 5 reported using of LLINs during travel. The main reasons for travel were to attend social events (weddings, funerals, overnight prayers) and for work. travellers who attended social events reported using LLINs less commonly than those who travelled for work. Challenges to using LLINs during travel included: (1) limited access to LLINs; (2) challenges in planning ahead of travel; (3) lack of space or ability to hang LLINs while travelling; (4) impression that LLINs in lodging places were unhygienic; (5) cultural beliefs discouraging use of LLINs during social events; (6) participation in overnight ceremonies; and (7) doubts about efficacy of LLINs. Positive factors influencing use of LLINs during travel included knowledge regarding malaria prevention and good affordability and availability of LLINs.ConclusionsDespite good traveller knowledge regarding malaria control measures, use of LLINs was limited. Use of LLINs in the prevention of malaria among travellers from low to high transmission settings needs to be prioritized. This calls for increased behaviour change oriented communication to improve traveller preparedness and consideration of use of repellents in situations where LLINs may not be feasible. The Uganda Ministry of Health and Malaria Control Division should use educational messages to increase awareness about the risks of getting malaria during overnight travel through the media. Truck drivers should be sensitized through their companies to use the available space at the back of the trucks for hanging nets and consider using pop-up nets.

Challenges and Opportunities for Use of Smart Materials in Designing Assistive Technology Products with, and for Older Adults

Despite the potential to support ageing in place, there is still low Assistive Technology (AT) uptake among older adults. Smart Materials (SMs) have the potential to play an important role in AT innovation without detracting from the aesthetic appearance and ease of use. The MATUROLIFE project aims to develop enhanced AT products for older adults by employing smart metallised textiles, through a design process involving older adult users and collaborating within a complex interdisciplinary space. This paper outlines research undertaken to capture the prioritised needs and design requirements of older adults, as well as their expectations of future technologies and understanding of SMs. Following interviews with older adults exploring AT acceptance, 94 older adults were engaged in a series of co-creation workshops. The findings emphasise a strong need to feel independent yet safe in older adulthood, and an uncompromised requirement to be fashionable without stigma and stereotypes. The participants demonstrated no resistance to the adoption of smart materials and technologies if they are integrated into AT products that are easy to use, comfortable and aesthetically pleasing, irrespective of the complexity and novelty of the technology involved.

Analysis on production of bioethanol for hydrogen generation.

Bioethanol is a renewable energy source carrier mainly produced from the biomass fermentation process. Reforming of bioethanol for hydrogen production is the most promising method from the renewable energy source. Production of hydrogen from ethanol reforming process is not only environmentally friendly, but also it produces greater opportunities for use of renewable energy source, which are available and affect the catalytic activity of the process. This paper reviewed the various reforming processes and associated noble and non-noble catalysts and supporting layers for the reforming process. Among that, electrochemical reforming of bioethanol is found to be cost-effective, and hydrogen production is also found to be of high purity. Hydrogen production from ethanol through various reforming processes is still in the research for better hydrogen production. Hydrogen production through the process of reforming can be widely used for fuel cell operations.

The Design and Development of a Food Composition Database for an Electronic Tool to Assess Food Intake in New Caledonian Families.

The food environment in New Caledonia is undergoing a transition, with movement away from traditional diets towards processed and discretionary foods and beverages. This study aimed to develop an up-to-date food composition database that could be used to analyze food and nutritional intake data of New Caledonian children and adults. Development of this database occurred in three phases: Phase 1, updating and expanding the number of food items to represent current food supply; Phase 2, refining the database items and naming and assigning portion size images for food items; Phase 3, ensuring comprehensive nutrient values for all foods, including saturated fat and total sugar. The final New Caledonian database comprised a total of 972 food items, with 40 associated food categories and 25 nutrient values and 615 items with portion size images. To improve the searchability of the database, the names of 593 food items were shortened and synonyms or alternate spelling were included for 462 foods. Once integrated into a mobile app-based multiple-pass 24-h recall tool, named iRecall.24, this country-specific food composition database would support the assessment of food and nutritional intakes of families in New Caledonia, in a cross-sectional and longitudinal manner, and with translational opportunities for use across the wider Pacific region.

Arthroscopically Assisted Fixation of Terrible Triad Variant Injuries of the Elbow With Small-Bore Needle Arthroscopy

The range of diagnostic and therapeutic applications of needle arthroscopy (NA) continue to expand due to advances in image quality and resolution. Minimally invasive techniques can be augmented by the smaller camera size and reduced fluid use made possible by NA. Small-bore arthroscopy presents opportunities for use in smaller joints, such as the elbow, where applications of standard arthroscopic equipment may be limited by small anatomic spaces and fluid extravasation. In this Technical Note, we present our technique for NA-assisted treatment of terrible triad injuries, specifically in the setting of an intact radial head. The technique describes a stepwise approach to arthroscopically aided fixation of the coronoid process, followed by open reconstruction of the lateral collateral ligament complex.

Investigating opportunities for use of alternative coagulants for drinking water treatment at Morton Jaffray Water Treatment works, Harare, Zimbabwe

Abstract Drinking water treatment at Harare's main water works, Morton Jaffray Water Treatment Works (MJWTW), has been a challenge due to source (Lake Chivero) pollution, and the efficacy of some of the processes and chemicals including aluminium sulphate (alum) has been questioned. This study investigated the use of an alternative coagulant to the traditional use of alum at MJWTW. The effectiveness of five coagulants, namely Anhydrous Poly Aluminium Chloride (APAC), Poly Aluminium Chloride (PAC), Primco 100, Zetafloc 4030 and alum (control) was investigated by flocculation tests in a laboratory using Lake Chivero water. Parameters analysed included pH, turbidity, Electrical Conductivity (EC) and chlorophyll-a for raw water and treated water. Raw water mean pH was 7 ± 0.4, turbidity (3.3 ± 0.2 NTU), EC (337 ± 5.0 μS/cm) and chlorophyll-a concentration (2.28 μg/L). Primco 100 had the best performance with the lowest optimum dosage of 25 mg/L while alum had the highest dosage of 55 mg/L. APAC, PAC, Primco 100 and Zetafloc 4030 did not change the pH of water significantly but alum did. The study concluded that Primco 100 was the most suitable coagulant and could be an alternative to alum.

Interactional spaces of a high-rise group housing complex and social cohesion of its residents: case study from Kolkata, India

From concerns of mental health problems and behavioural issues of residents of high-rises, this research tries to explore the association of interactional spaces (the spaces of interaction in a high-rise housing) with dimensions of social cohesion (the social relations) of the residents. Presuming social cohesion is an important determinant of their mental health. To have both the researchers’ and users’ perspectives while an investigation, this research incorporates perception of the residents, analysis of layout plan, behaviour observation and space syntax analysis. Later, with the help of hierarchical linear regression model it identifies the significant attributes and uses of interactional spaces (both at outdoor and indoor) that facilitate or inhibit social cohesion. The finding indicates that the arrangement and use of the streets and tot-lots within a housing complex have a significant contribution in strengthening social cohesion of the residents. Further, more than actual use, the opportunities of a chance encounter and opportunities of use of the spaces appear to be more effective. The findings of the research would have a wider application not only in high-rise group housing but other instances as well.

A Model for Examining Challenges and Opportunities in Use of Cloud Computing for Health Information Systems

Health Information Systems (HIS) are becoming crucial for health providers, not only for keeping Electronic Health Records (EHR) but also because of the features they provide that can be lifesaving, thanks to the advances in Information Technology (IT). These advancements have led to increasing demands for additional features to these systems to improve their intelligence, reliability, and availability. All these features may be provisioned through the use of cloud computing in HIS. This study arrives at three dimensions pertinent to adoption of cloud computing in HIS through extensive interviews with experts, professional expertise and knowledge of one of the authors working in this area, and review of academic and practitioner literature. These dimensions are financial performance and cost; IT operational excellence and DevOps; and security, governance, and compliance. Challenges and drivers in each of these dimensions are detailed and operationalized to arrive at a model for HIS adoption. This proposed model detailed in this study can be employed by executive management of health organizations, especially senior clinical management positions like Chief Technology Officers (CTOs), Chief Information Officers (CIOs), and IT managers to make an informed decision on adoption of cloud computing for HIS. Use of cloud computing to support operational and financial excellence of healthcare organizations has already made some headway in the industry, and its use in HIS would be a natural next step. However, due to the mission′s critical nature and sensitivity of information stored in HIS, the move may need to be evaluated in a holistic fashion that can be aided by the proposed dimensions and the model. The study also identifies some issues and directions for future research for cloud computing adoption in the context of HIS.
