Authors: Amine El Badlaoui  , Mariam Cherqaoui  , Issam Er-Rami
Published: June 2023

The purpose of this paper is to review the empirical literature on value relevance of audit reports by providing current evidence on the market reaction to modified audit opinions (MAOs). This study is motivated by the argument that recent research has resolved the research designs problems raised by the pre-2010 studies that resulted in unmitigated and contradictory results. We adopt a systematic literature review based on the guidelines presented by Kitchenham et al. to review papers published between 2010 and 2020. The main findings of our review show sufficient evidence that MAOs are indeed useful to investors in making decisions in developed countries, which is evidenced by the fact that the MAOs have a negative effect on the share prices of companies. In contrast, evidence from studies conducted in developing countries shows null market reaction to MAOs, with the exception of the Chinese market, which shows a significant reaction. The methodological limitations and alternative causes behind the null market reaction to MAOs of studies conducted in developing countries are discussed in this paper.
The Impact of Industry-Adjusted Profitability and S-Curve Targeted Industry on Capital Structure: Evidence from Thailand
Authors: Sirada Nuanpradit
Published: June 2023

This study examines the impact of industry-adjusted profitability and S-curve targeted industries under an innovation-driven economy on firms’ capital structures in Thailand. The results demonstrate that a superior degree of industry-adjusted profitability reduces the need for debt financing. Within the industry, franchise and harvest firms with sufficient earnings have a lower debt overhang than under-performing firms. Furthermore, the S-curve targeted industries, which typically use debt to finance their expensive investments, appear to use fewer loans when they feel pressured by the investment support policy to intensify research and development (R&D) activities. Overall, in the emerging market geared toward a new economic roadmap, firms’ capital structures are shaped by competitive performance as well as industry and policy forces.

Published: June 2023

Plastic pollution is causing worldwide concern, especially after evidence that the various types of plastic degrade into particles of smaller sizes; known as micro- and nanoplastics. The origin of the plastics in the environment is related to human actions. The objective of this review is to describe the main routes of microplastic input in the Amazonian rivers and how local environmental characteristics can affect the transformation of plastics into microplastics until their absorption by aquatic organisms. The current situation regarding the presence of microplastic particles in freshwater is analyzed considering the environmental dynamics of the region, and focuses on rivers, estuaries and sediments, their effects on organisms, especially on fish, followed by the transportation of microplastic particles to the sea. Amapá, Amazonas, Pará and Mato-Grosso are the states of the Brazilian Amazon with scientific reports on the characterization of microplastic particles in sediment, water, and fish. These studies are local and descriptive and most of them highlight the characterization of microplastics. There is a need for field research in the various microregions of the Amazon, as well as actions to mitigate the damage, including to riverine populations, that is caused by these pollutants in the region.
Quality and Safety of Wine during Storage: Packaging and Stopper
Authors: Chemisova Larisa , Ageyeva Natalia , Yakimenko Elena
Published: June 2023

Poor packaging often affects the quality and safety indicators of wine during storage. The need to preserve and prolong wine stability during long-term storage requires a comprehensive study of processes that occur in wines packaged and capped in various ways.

This research featured 56 samples of white and red dry wines, which were bottled in four types of packages and stopper for 18 months. The effect of synthetic and natural stopper methods involved a model system that simulated the main composition of wine in line with the EAEU standards. The contents of free SO2 and dissolved oxygen, as well as the microbiology of natural corks, were studied using standard methods. The analysis of volatile substances relied on gas chromatography, mass spectrometry, and solid phase micro-extraction.

The study recorded critical changes in the quality of wine products, characterized by increased oxidation markers and low free sulfur dioxide, which fell below 10 mg/dm3. In polyethylene terephthalate bottles, these changes occurred after 12 months of storage, while it took them 18 months to develop in multilayer bags and combined packaging materials. The components of natural and artificial plugs of microbial and chemical origin entered the model systems after 10 days of contact. The microbiological contamination was twice as high as the permissible level. The migration of microbial and chemical substances into the wine samples spoiled their quality and safety.

The effect of packaging on the oxidative processes in white and red dry wines during storage resulted in different concentrations of dissolved oxygen and sulfur dioxide. The results can help wine producers to choose the most appropriate packaging and stopper means depending on the wine sort and its subsequent storage conditions. Alternative types of packaging proved to have a limited shelf life.

Published: June 2023

Healthy foods and green processing are currently in the focus of scientific attention. Flax is considered a superfood that includes numerous beneficial ingredients. Its oil is a great source of polyunsaturated fatty acids. However, the heat-sensitive futures of the polyunsaturated fatty acids require low-temperature methods. Screw pressing can produce oils at lower temperatures, but a lower oil capacity makes it less advantageous. Pre-treatment of seeds as a crucial pre-processing stage affects the quality and quantity of oil. This research featured the effect of moisture content in flax seeds on the quantity and quality flax seed oil.

The study involved local flax (Linum usitatissimum L.) from the Qashqadaryo Region, Uzbekistan. Standard methods were used to define the quality parameters of oil, i.e., acid value, free fatty acids content, peroxide value, oil recovery, and sediment content. Regression equations were obtained using the method of regression analysis.

The highest oil recovery of 40.99% was observed at the moisture content of 9.56%. At 7.55%, the oil recovery dropped by 3.17%. The sediment content in the oil increased at lower moisture contents in the flax seeds (14.62–5.55%). The acid value, peroxide value, and free fatty acid content demonstrated both downward and upward trends when the moisture content increased.

The moisture content in flax seeds affected the quality and quantity profile of screw-pressed oil. The optimal parameters of oil processing can yield health-beneficial and highly nutritional oil.
La dinámica de las redes sociopolíticas en la acción colectiva del movimiento afrodescendiente de las Américas
Authors: Antón Sánchez Jhon Herlyn , Santacruz Palacios Marcia
Published: June 2023

Este artículo analiza la dinámica sociopolítica del movimiento social afrodescendiente a partir de la estructuración de redes de interacción. Sostenemos que las redes sociopolíticas han constituido la estrategia de incidencia y acción colectiva del movimiento social, especialmente en el ámbito transnacional. Sin embargo, la falta de continuidad de procesos, el escaso financiamiento y la dispersión generan una debilidad manifiesta en el logro de las agendas. La variedad de redes que van desde las afrocéntricas hasta las institucionales, como sus ideologías de izquierda y de derecha, son consideraciones que deben tenerse en cuenta al momento de impulsar proyectos de empoderamiento. No obstante, habría que dar más atención a las redes de carácter afrocéntrico, pues son más autónomas, independientes y perdurables.

The addition of cellulolytic fungi, or their enzymes, in diets containing high levels of fiber are promising strategy for improving the performance. In this study, the aims were to select cellulolytic fungi from the digestive tract of sheep fed different concentrations of banana leaf hay. Thirty lambs raised in a feedlot were evaluated, distributed in a completely randomized design, with diets containing 0, 125, 250, 375, or 500 g/Kg of dry matter and six replications. Approximately 15 mL of ruminal fluid and swabs from the rectal ampulla were collected. The cultures were carried out in a medium containing microcrystalline cellulose (C medium). The mycelial fungi isolates were identified through the microculture technique. Among the fungi from the ruminal fluid, 23 isolates corresponded to the genus Aspergillus and three to Paecilomyces spp. Among the isolates from the rectal ampulla, seven were A. spp., and three were P. spp. The A. genus predominated among the isolates from both evaluated sites (p <0.05). Fragments of these fungi were inoculated in triplicate in medium C at 37 °C and the cellulolytic activity index (CAI) was determined after 24, 48, and 72 hours of incubation. There was no difference in the CAI of Aspergillus spp. from animals fed different diets or of different evaluated sites (P > 0.05). However, 22 isolates of Aspergillus spp. and three of Paecilomyces spp. showed a CAI > 1, indicating biotechnological potential for cellulase production. These selected isolates could be selected for the elaboration of microbial additives in ruminant diets.
The Potential Strategies for Overcoming Multidrug Resistance and
Reducing Side Effects of Monomer Tubulin Inhibitors for Cancer
Therapy
Authors: Cui Yingjie , Zhang Jing , Zhang Guifang
Published: June 2023

Background:

Tubulin is an essential target in tumor therapy, and this is attributed
to its ability to target MT dynamics and interfere with critical cellular functions,
including mitosis, cell signaling, and intracellular trafficking. Several tubulin inhibitors
have been approved for clinical application. However, the shortcomings, such as drug resistance
and toxic side effects, limit its clinical application. Compared with single-target
drugs, multi-target drugs can effectively improve efficacy to reduce side effects and overcome
the development of drug resistance. Tubulin protein degraders do not require high
concentrations and can be recycled. After degradation, the protein needs to be resynthesized
to regain function, which significantly delays the development of drug resistance.

Methods:

Using SciFinder® as a tool, the publications about tubulin-based dual-target inhibitors
and tubulin degraders were surveyed with an exclusion of those published as patents.

Results:

This study presents the research progress of tubulin-based dual-target inhibitors
and tubulin degraders as antitumor agents to provide a reference for developing and applying
more efficient drugs for cancer therapy.

Conclusion:

The multi-target inhibitors and protein degraders have shown a development
prospect to overcome multidrug resistance and reduce side effects in the treatment of tumors.
Currently, the design of dual-target inhibitors for tubulin needs to be further optimized,
and it is worth further clarifying the detailed mechanism of protein degradation.

Published: June 2023

Asthma is a chronic heterogeneous airway obstruction disorder defined by a complex
cascade of pathophysiological conditions that lead to recurring bronchial hyper-responsiveness and
underlying inflammation, lowering the patient’s quality of life. Despite the availability of various
synthetic medications for the management of asthma, it has become one of the leading causes of
death worldwide. Furthermore, the present allopathic treatment possesses severe long-term negative
effects, which make people more attracted to the safer and easily available indigenous traditional
and Ayurvedic system of medicine. Ayurveda is regarded as the “Mother of all healing” and “Science
of Life,” which treats all the ailments, including asthma, by restoring a balance between three
main components of the body- Vata, Pitta, and Dosha. Various clinically effective and less toxic anti-
asthmatic Ayurvedic herbal preparations are available for the management of asthma and related
complications which act by causing mast cell deactivation, inhibition of Th1, Th2, Th7 response, Tcell
suppression, etc., therefore, efforts have been made to compile all the relevant literature related
to the ayurvedic anti-asthmatic formulations and scrutinize the efficacy of selected plants present in
the majority in those formulations in asthma along with the structure and mode of action of phytoconstituent
responsible for designing novel molecules with better efficacy. Research on these selected
plants can also have economic significance as various constituents isolated from these plants for
their anti-asthmatic effect can further be explored to discover their potential in medicinal, diagnostic
and cosmetic field.

Authors: Pandey Kavita , Chandak Abhimanyu
Published: June 2023

Plant diseases are one of the major contributors to economic loss in the agriculture industry
worldwide. Detection of disease at early stages can help in the reduction of this loss. In recent
times, a lot of emphasis has been done on disease detection due to the overall increase in production
as well as the loss of grape number. With deep learning, having a promising future and having the
advantages of automatic learning and feature extraction, the use of these techniques has now been
widely spread. This paper reviewed the existing deep-learning techniques available for grape disease
detection. Firstly, covering the various steps in a grape disease detection model ranging from
the various sources of image acquisition, the different image augmentation techniques and the various
models used, and the parameters required to evaluate. Secondly, the study summarizes the important
findings of all literature available on the theme. The paper also tries to highlight the various
challenges faced by the researchers and the common trend among them, so that future research on
the topic can achieve higher performance.
Molecular Imaging and Contrast Agents

Published: June 2023

As an emerging technology, molecular imaging combines advanced imaging
technology with cellular and molecular biology to highlight physiological or
pathological processes in living organisms at the cellular level. The main advantage of
in vivo molecular imaging is its ability to characterize pathologies of diseased tissues
without invasive biopsies or surgical procedures. Such technology provides great hope
for personalized medicine and drug development, as it can potentially detect diseases in
early stages (screening), identify the extent of a disease/anomaly, help to apply directed
therapy, or measure the molecular-specific effects of a given treatment. Molecular
imaging requires the combination of high-resolution/sensitive instruments with targeted
imaging agents that correlate the signal with a given molecular event. In ongoing
preclinical studies, new molecular targets, which are characteristic of given diseases,
have been identified, and as a consequence, sophisticated multifunctional probes are in
perpetual development. In this context, the discovery of new emerging chemical
technologies and nanotechnology has stimulated the discovery of innovative
compounds, such as multimodal molecular imaging probes, which are multiplex
systems that combine targeting moieties with molecules detectable by different
imaging modalities.

Published: June 2023

The use of prosthesis plays an important role in rehabilitation in the case of
congenital absence or loss of an extremity. Apart from lower and upper extremity
prostheses, there is a wide variety of prostheses used in different parts of the body.
Unlike limb prostheses, these are permanently placed in the body by surgical
intervention and are also called implants. New studies emerge every day in the
development of innovative prostheses and implants. These innovations include material
selection, new material development, control strategies, feedback system development,
sensor and actuator development, power supply methods, and power equipment
development work. Besides, many studies aim to increase user comfort as well as
acceptance rate and the useful life of prostheses. Some researchers are working to
develop prostheses exclusively for the use of children. Innovative developments in
prostheses and implants are examined in this section. Developments are presented from
various aspects, and information is given about the research that has made significant
contributions to the field. As an example of technological development in prosthetics,
an autonomic tumor prosthesis developed for children with bone cancer is introduced at
the end of the section as a case study.

Published: June 2023

Cancer is a disease in which cells grow uncontrollably and spread to
different tissues. Existing treatment methods developed for cancer do not allow this
disease to be completely cured, and these methods have various side effects. The search
for effective cancer treatment has encouraged scientists to produce new ideas with
nanotechnological methods. With the help of nanotechnological methods, which are
becoming more popular day by day, the material is reduced to nano size, where it
shows quantum effect, and gains unique physicochemical, mechanical, and biological
properties. Thanks to the large surface area of the nanocarriers, more drug loading can
be achieved on the unit surface, and their easy modification procedures enable these
materials to be conjugated with biological molecules to become more specific
structures. Due to the several advantages of nanocarriers, such as different synthesis
methods, being open to modification, and relatively easy production, these materials
can provide effective delivery of cancer drugs and even increase their efficacy.
Moreover, there are also many nanodrugs approved for different routes of
administration. Thanks to all these features, nanocarriers are promising ways to
develop new drug formulations for cancer treatment. In this chapter, the anticancer
activity of nanocarriers synthesized by different methods is clarified. Besides, the
effects of the nanocarriers on different types of cancer, the targeting strategies of
nanocarriers, and the effects of their size, surface charge, and shape, on their anticancer
activity are summarized.
Application of Bioceramics to Cancer Therapy
Authors: Hanaei Shirin B. , Reinwald Yvonne
Published: June 2023

Despite the great medical developments, cancer remains the main cause of
death amongst individuals under 85 years. Novel therapeutic approaches for cancer
therapy are constantly being developed, and bioactive ceramics show great promise in
this respect. Bioceramics contain inorganic components, which help in the repair,
replacement, and regeneration of human cells; for that reason, their use is growing in
scope. Bioceramics have a flexible nature and can be modified with biologically active
substances for a particular treatment or improvement of tissue or organ functionality.
Materials, including glass-ceramics and calcium phosphate, can be loaded with specific
drugs, growth factors, peptides, and hormones in a particular fashion. Also, for the
elimination of infections and inflammations after surgery, the surface of bioceramics
can be modified, and antibiotics can be introduced to prevent bacterial biofilm
formation. In the context of bone cancer diagnosis and treatment, mesoporous
bioceramics have demonstrated excellent properties not only for being osteoinductive
and osteoconductive but also for drug delivery, therefore, being rendered as a
remarkable platform for the creation of bone tissue engineering scaffolds for the
purpose of bone cancer treatment. Furthermore, the creation of ceramic magnetic
nanoparticles as thermoseeds for hyperthermia exhibits promising development for
cancer treatment. The conjugation of ceramic nanoparticles with therapeutic agents and
heat treatment via different magnetic fields improve the efficacy of hyperthermia to the
extent that it makes them an alternative to chemotherapy. This chapter discusses the
therapeutic value of bioceramics.
Impact of Beliefs About Local Physician Supply and Self-Rated Health on Willingness to See a Nurse Practitioner During the COVID-19 Pandemic: Web-Based Survey and Experiment
Authors: Campos-Castillo Celeste
Published: June 2023

Background

The COVID-19 pandemic overburdened primary care clinicians. For nurse practitioners (NPs) to alleviate the burden, the public must be willing to see an NP over a physician. Those with poor health tended to continue seeking care during the pandemic, suggesting that they may be willing to see an NP.

Objective

The aim of this study is to evaluate the public’s willingness to see an NP for primary care and how this may be associated with their beliefs about the local supply of physicians and self-rated health. Two studies were conducted: (1) a survey to identify correlations and (2) an experiment to assess how willingness is dependent on information about the local supply of physicians.

Methods

The survey and experiment were conducted digitally in April and December 2020, respectively. Participants were US adults recruited from Amazon’s Mechanical Turk platform. The key independent variables were self-rated health, which was a dichotomized 5-point scale (excellent, very good, good vs fair, and poor), and beliefs about local physician supply. The survey measured beliefs about local physician supply, while the experiment manipulated beliefs by altering information the participants read about the local supply of physicians. Willingness to see an NP was assessed in 2 ways. First as an overall preference over a physician and the second as a preference given 2 clinically significant scenarios in which participants imagined they were experiencing either coughing or a headache (presentation order randomized). Multiple regressions and ANOVAs were used to assess how beliefs about the local physician supply and self-rated health were associated with overall willingness to see an NP. Bivariate probits simultaneously estimated willingness to see an NP in the 2 clinically significant scenarios.

Results

The survey showed that concerns about physician supply were associated with lower willingness to see an NP among respondents with comparatively better health but a greater willingness among respondents with comparatively worse health. The experiment suggests that only the latter is causal. For the 2 clinically significant scenarios, these patterns appeared for the coughing scenario in the survey and the headache scenario in the experiment.

Conclusions

US adults with comparatively worse self-rated health become more willing to see an NP for primary care when they hear information that raises their concerns about the local physician supply. The differences between the survey and experiment results may be useful for interpreting findings from future studies. Findings may aid in managing finite health care resources during public health crises and crafting successful messaging by NP advocacy groups. Efforts to address nursing shortages will also be needed.
Factors Influencing Clinicians’ Use of Hospital Information Systems for Infection Prevention and Control: Cross-Sectional Study Based on the Extended DeLone and McLean Model
Authors: Zheng Feiyang , Wang Kang , Wang Qianning , Yu Tiantian , Wang Lu , Zhang Xinping , Wu Xiang , Zhou Qian , Tan Li
Published: June 2023

Background

Healthcare-associated infections have become a serious public health problem. Various types of information systems have begun to be applied in hospital infection prevention and control (IPC) practice. Clinicians are the key users of these systems, but few studies have assessed the use of infection prevention and control information systems (IPCISs) from their perspective.

Objective

This study aimed to (1) apply the extended DeLone and McLean Information Systems Success model (D&M model) that incorporates IPC culture to examine how technical factors like information quality, system quality, and service quality, as well as organizational culture factors affect clinicians’ use intention, satisfaction, and perceived net benefits, and (2) identify which factors are the most important for clinicians’ use intention.

Methods

A total of 12,317 clinicians from secondary and tertiary hospitals were surveyed online. Data were analyzed using partial least squares-structural equation modeling and the importance-performance matrix analysis.

Results

Among the technical factors, system quality (β=.089-.252; P<.001), information quality (β=.294-.102; P<.001), and service quality (β=.126-.411; P<.001) were significantly related to user satisfaction (R2=0.833), use intention (R2=0.821), and perceived net benefits (communication benefits [R2=0.676], decision-making benefits [R2=0.624], and organizational benefits [R2=0.656]). IPC culture had an effect on use intention (β=.059; P<.001), and it also indirectly affected perceived net benefits (β=.461-.474; P<.001). In the importance-performance matrix analysis, the attributes of service quality (providing user training) and information quality (readability) were present in the fourth quadrant, indicating their high importance and low performance.

Conclusions

This study provides valuable insights into IPCIS usage among clinicians from the perspectives of technology and organization culture factors. It found that technical factors (system quality, information quality, and service quality) and hospital IPC culture have an impact on the successful use of IPCISs after evaluating the application of IPCISs based on the extended D&M model. Furthermore, service quality and information quality showed higher importance and lower performance for use intention. These findings provide empirical evidence and specific practical directions for further improving the construction of IPCISs.
Graded Response Model Analysis and Computer Adaptive Test Simulation of the Depression Anxiety Stress Scale 21: Evaluation and Validation Study
Authors: Kraska Jake , Bell Karen , Costello Shane
Published: June 2023

Background

The Depression Anxiety Stress Scale 21 (DASS-21) is a mental health screening tool with conflicting studies regarding its factor structure. No studies have yet attempted to develop a computer adaptive test (CAT) version of it.

Objective

This study calibrated items for, and simulated, a DASS-21 CAT using a nonclinical sample.

Methods

An evaluation sample (n=580) was used to evaluate the DASS-21 scales via confirmatory factor analysis, Mokken analysis, and graded response modeling. A CAT was simulated with a validation sample (n=248) and a simulated sample (n=10,000) to confirm the generalizability of the model developed.

Results

A bifactor model, also known as the “quadripartite” model (1 general factor with 3 specific factors) in the context of the DASS-21, displayed good fit. All scales displayed acceptable fit with the graded response model. Simulation of 3 unidimensional (depression, anxiety, and stress) CATs resulted in an average 17% to 48% reduction in items administered when a reliability of 0.80 was acceptable.

Conclusions

This study clarifies previous conflicting findings regarding the DASS-21 factor structure and suggests that the quadripartite model for the DASS-21 items fits best. Item response theory modeling suggests that the items measure their respective constructs best between 0θ and 3θ (mild to moderate severity).

Published: June 2023

Background

Public safety personnel (PSP) are exposed to traumatic events due to their work environments, which increases the risk of mental health challenges. Providing effective and evidence-based interventions, such as SMS text messaging programs, can improve PSP's overall mental well-being with high user satisfaction rates.

Objective

This study aims to evaluate users’ satisfaction, receptiveness, and perceptions of a cognitive behavioral therapy (CBT)–based supportive SMS text messaging intervention (Text4PTSI).

Methods

Participants self-subscribed to Text4PTSI and received unidirectional cognitive behavioral–based supportive text messages for 6 months. Participants completed a web-based survey delivered via SMS text message at enrollment, and 6 weeks, 3 months, and 6 months post enrollment. Respondents’ perception and receptivity of the program were assessed using a questionnaire measured on a 5-point Likert scale. Data were collected as categorical variables, and overall satisfaction with the Text4PTSI program was measured on a scale from 0 to 100.

Results

There were 131 subscribers to the Text4PTSI program; however, only 81 subscribers responded to the survey, producing 100 survey responses across the 3 follow-up time points. The overall mean score of satisfaction was 85.12 (SD 13.35). More than half of the survey responses agreed or strongly agreed that Text4PTSI helped participants cope with anxiety (79/100 responses, 79%), depressive symptoms (72/100 responses, 72%), and loneliness (54/100 responses, 54%). Similarly, most of the survey responses agreed or strongly agreed that the Text4PTSI program made respondents feel connected to a support system, improved their overall mental well-being (84/100 responses, 84%), felt more hopeful about managing concerns about their mental health or substance use (82 out of responses, 82%), and helped enhance their overall quality of life (77/100 responses, 77%). The available survey responses suggest that the majority always read the supportive text messages (84/100 responses, 84%), took time to reflect on each message (75/100 responses, 75%), and returned to read the text messages more than once (76/100 responses, 76%).

Conclusions

PSP who responded to the follow-up surveys reported high user satisfaction and appreciation for receiving the Text4PTSI intervention during the 6-month program. The reported satisfaction with the service provided could pave the way to ensuring a better uptake of the service with potential effectiveness to end users.

There were 131 subscribers to the Text4PTSI program; however, only 81 subscribers responded to the survey, producing 100 survey responses across the 3 follow-up time points. The overall mean score of satisfaction was 85.12 (SD 13.35). More than half of the survey responses agreed or strongly agreed that Text4PTSI helped participants cope with anxiety (79/100 responses, 79%), depressive symptoms (72/100 responses, 72%), and loneliness (54/100 responses, 54%). Similarly, most of the survey responses agreed or strongly agreed that the Text4PTSI program made respondents feel connected to a support system, improved their overall mental well-being (84/100 responses, 84%), felt more hopeful about managing concerns about their mental health or substance use (82 out of responses, 82%), and helped enhance their overall quality of life (77/100 responses, 77%). The available survey responses suggest that the majority always read the supportive text messages (84/100 responses, 84%), took time to reflect on each message (75/100 responses, 75%), and returned to read the text messages more than once (76/100 responses, 76%).

CONCLUSIONS

PSP who responded to the follow-up surveys reported high user satisfaction and appreciation for receiving the Text4PTSI intervention during the 6-month program. The reported satisfaction with the service provided could pave the way to ensuring a better uptake of the service with potential effectiveness to end users.

Nước thải sơ chế gà rán công nghiệp sau khi tiền xử lý bằng ozone vẫn còn chứa một lượng đạm, lân cần được quan tâm xử lý. Nghiên cứu được thực hiện bằng cách sử dụng cây sậy (Phragmites australis) trồng trong hệ thống đất ngập nước chảy ngầm ngang nhằm đánh giá khả năng hấp thu lượng đạm, lân trong loại nước thải này. Thí nghiệm được bố trí gồm 01 nghiệm thức thí nghiệm và 01 nghiệm thức đối chứng (mỗi nghiệm thức có độ lặp là 03 lần). Mỗi nghiệm thức được xây dựng bằng gạch bê tông có kích thước dài x rộng x cao lần lượt là 8 m x 0,4 m x 0,5 m, được nạp tải 330 lít nước thải với thời gian lưu nước 03 ngày. Sau khi thí nghiệm kết thúc, sậy sinh trưởng và phát triển tốt. Chiều cao trung bình của sậy đạt 166 cm/cây. Trọng lượng tươi và khô (TLK) trung bình của sậy đạt tương ứng 83 và 23 g/cây. Hàm lượng đạm trong thân và rễ sậy đạt tương ứng 0,611±0,014% và 0,333±0,009% TLK. Hàm lượng lân trong thân và rễ sậy đạt 0,096±0,004% và 0,088±0,005% TLK. Cây sậy giúp hấp thu 11,22% đạm và 8,88% lân trong nước thải đầu vào. Nước thải sau khi xử lý bằng đất ngập nước đạt tiêu chuẩn xả thải cột B – QCVN 40:2011/BTNMT.

Mục tiêu của nghiên cứu này là đánh giá khả năng áp dụng tấm Jmat làm giá thể vi sinh  (biocarrier) trong hệ thống lọc sinh học ngập nước hiếu khí xử lý nước thải sinh hoạt. Ba mô hình thí nghiệm được thiết kế chiều cao lớp giá thể 0,9 m và ngập hoàn toàn trong nước thải. Các cột lọc được nạp nước thải bằng bơm nhu động với 2 tải nạp lần lượt là 2 m3/m2.ngày và 4 m3/m2.ngày. Kết quả nghiên cứu cho thấy nồng độ chất ô nhiễm trong nước thải sau xử lý thấp và đạt QCVN 14:2008/BTNMT. Tấm lọc Jmat được sử dụng làm giá thể trong lọc sinh học ngập nước mang lại hiệu suất loại bỏ chất ô nhiễm cao. Hiệu suất xử lý SS là: 95,8%, COD: 92,5%, BOD5: 93,5%, TKN: 94,0%. Nồng độ NO3- đầu ra của mô hình cao hơn đầu vào, cho thấy quá trình nitrate hóa diễn ra tốt. Khi tăng gấp đôi tải nạp thì hiệu suất loại bỏ các chất giảm nhưng các chỉ tiêu SS, PO43-, COD, BOD5, TKN vẫn đạt QCVN 14-MT:2008/BTNMT (loại A). Dựa trên kết quả nghiên cứu này, tấm Jmat có thể sử dụng làm giá thể vi sinh trong hệ thống lọc sinh học để xử lý các chất ô nhiễm trong nước thải sinh hoạt.

Cartap là một trong những hoạt chất thuốc BVTV được cho phép sử dụng ở Việt Nam và được sử dụng khá phổ biến trong canh tác lúa ở đồng bằng sông Cửu Long. Cá Chép (Cyprinus Carpio) là loài được nuôi trong mô hình lúa – cá nên chúng thường xuyên bị phơi nhiễm với thuốc BVTV sử dụng cho lúa. Nghiên cứu nhằm: (1) xác định giá trị LC50-96 giờ của Cartap đối với cá Chép, (2) hoạt tính enzym cholinesterase ở cá Chép bị lật bụng, co cơ và chết sau phơi nhiễm với thuốc ở nồng độ gây chết, (3) xác định ảnh hưởng của thuốc Cartap đến tiêu hao oxy và ngưỡng oxy cá chép. Kết quả nghiên cứu cho thấy, giá trị LC50-96 giờ của hoạt chất Cartap có trong thuốc trừ sâu Padan 95SP đối với cá Chép là 1,343 ppm. Tỷ lệ ChE của cá Chép bị ức chế khoảng 30% làm cá bị co cơ và khi ChE bị ức chế khoảng 50% làm cá lật bụng. Cá chết ở nồng độ gây chết có ChE bị ức chế thấp (50%) và nguyên nhân cá chết có thể do mang cá đã bị tổn thương nên không lấy đủ oxy cho nhu cầu cơ thể. Cartap hydrochloride có xu hướng làm tăng cường độ hô hấp của cá chép. Cần nghiên cứu sâu những ảnh hưởng của Cartap lên cấu trúc mang cá chép...

Abstract: Now-a-days, IOT implementation has been a trend-worldwide. The ease of operation, power savings, and the analytical data that we gather from those devices has been a big boon for the industry. However, hassle-free adoption of newer systems, has always been an issue in terms of monetary costs as well as in regards to the familiarity with the original design. While there have been many studies which have focused on the aspects of costs, seldom they are with the objective of facilitating ease of transition from one familiar class of generation of products to the next. Our prototype product taps into this very aspect of familiarity. It is based on a microcontroller-based relay system, comprising of Node MCU - ESP-8266 microcontroller, relay module and household piano buttons. It facilitates ease of operation, while maintaining backwards compatibility. Our prototype is a blend of two systems, with traditional system working in conjunction with the new IOT based systems, making a hassle-free user experience, while at the same time increasing the safety and durability of the switches.
