A Hybrid Approach for Quantitative Analysis of Fire Hazards in Enclosed Vehicle Spaces on Ro-ro Passenger Ships
Authors: Bao Junzhong , Bian Zhijie , Li Bitong , Li Yan , Gong Yuguang
Published: August 2023

This study probes the probabilistic features of major fire hazards in enclosed spaces to establish their importance to the occurrence of fires onboard Ro-ro passenger ships and, in turn, to raise effective operational countermeasures. Distinct from the previous studies, the present research employs Bayesian Network (BN) analysis to determine the probabilities of fire hazards more effectively. The results of the first 10 important basic events obtained by the BN model are divided into five groups (Vehicle electrical fires, Reefer vehicle fires, Vehicle-carried cargo fires, Potential causal factors of fire for LIB vehicles, and Vehicle fires originating from human factors), Which prompts the authors to propose preventive measures for mitigating the possibility of fire occurrence on this type of electric vehicle. It is hoped that these measures can be essential justifications for establishing relevant rules regarding carrying LIB vehicles in enclosed spaces on an international level.

Internationally, energy-storage technologies have facilitated the large-scale utilization of renewable energy, reducing reliance on conventional power generation and enhancing energy efficiency. In the pursuit of strengthening the efficiency of phase-change energy-storage systems, the focus lies on further enhancing the efficiency of vertical shell-and-tube energy-storage systems. This study investigates the influence of two different heat-transfer fluid (HTF) injection directions on the melting of phase-change materials (PCM) in a vertical shell-and-tube latent heat storage (LHS) system. The melting behavior of PCM is analyzed under both pure conduction and natural convection conditions. The research findings reveal that during the initial melting stage, both HTF injection methods primarily rely on thermal conduction, resulting in no significant changes in PCM melting. However, in the later stages of natural convection, bottom HTF injection exhibits superior heat-transfer efficiency compared to top injection. Under a constant volume of phase-change material, both pipe length and pipe thickness affect the PCM melting process. As the pipe length increases within the range of 1.6 m to 0.2 m, the PCM melting time also increases. The results show that the melting time of the PCM is reduced by almost 15,000 s when the tube length H exceeds 800 mm, regardless of whether the heat-transfer fluid is injected at the top or bottom. In this paper, we also obtained results that the three composites containing 10% expanded graphite save 5.3%, 10.2%, and 14.3% of melting time, respectively, compared to pure paraffin when H = 200 mm and top injection are considered. For bottom injection, the three composites saved 7.7%, 12.5%, and 17.2% of melting time, respectively. This further emphasizes the more significant effect of priming in improving melting time.
Experimental Study on the Static Behavior and Recovery Properties of CFRP/SMA Composites

Published: August 2023

Strengthening reinforced concrete elements with externally bonded prestressed fiber reinforced polymer (FRP) sheets has become a popular reinforcement technology in recent years. However, in practical engineering applications, due to the limitations of construction operation space and the need for specialized design of tensioning and anchoring devices, it is very cumbersome to apply prestressing force to FRP sheets. Therefore, using the recovery effect of shape memory alloys (SMA) to introduce prestressing into FRP sheets can innovate a new approach by combining FRP sheets and SMA wires. In order to study the basic mechanical properties of FRP/SMA composites, carbon fiber reinforced polymer and shape memory alloys were used to make the composite specimens, and uniaxial tensile tests were carried out on them. The mechanical properties such as the stress-strain curve, failure mode, ultimate tensile strength and fracture strain were obtained. The test results show that CFRP sheet exhibits obvious linear elastic behavior in tensile tests. The stress-strain curve of SMA wire can be divided into four stages: the linear elastic stage, yield stage, strengthening stage and failure stage. The fracture strain at failure can reach 7%, which indicates excellent deformation properties. The loading and unloading cycles have little effect on the mechanical properties of SMA wire. With the increase in the loading rate, the ‘stress plateau’ section of the phase transformation section of the SMA wire hysteresis curve gradually transits to an oblique upward curve. Increasing the pre-strain value within a certain range can improve the resilience of SMA wires. SMA wires with a pre-strain value of 8% can provide a maximum resilience of 514 MPa after heating to the austenitic state. A prediction model for the number of temperature cycles and maximum recovery force of SMA was proposed and validated. According to this model, the SMA wires can still provide stable resilience after 30 cycles. Increasing the amount of wire (volume ratio) can improve the maximum fracture strain and ultimate tensile strength of CFRP/SMA composite specimens, and the more wire is added, the greater the residual strength after fracture. The diameter of the fiber can significantly reduce the maximum fracture strain and ultimate tensile strength of the FRP/SMA composite specimen.

The development of highly nutritious bakery products with optimum utilization of food waste is a major challenge for the food industry. The optimum utilization of food waste for the sustainable development goal of the country is important for the growth of the nation. The aim of the present work is to prepare value-added composite flour-mixed bread from waste fruit and vegetables. The composite flour was prepared in four formulations of peel and pomace with wheat flour (PPWF), as PPWF1, PPWF2, PPWF3, and PPWF4. Composite flour was blended with a mix of vegetable and fruit pomace powders and whole wheat flour. Indian gooseberry pomace powder, apple pomace powder, bottle gourd peel powder, and potato peel powder were used with whole wheat flour to make pomace and whole wheat flour compositions such as PPWF1, PPWF2, PPWF3, and PPWF4. Out of these four flours, PPWF3 contained a good amount of fiber 8.16%, crude protein 3.18%, total phenolic content 14.48%, moisture 9.5%, vitamin C 13.64 mg/100 g, and total phenolic compound 14.48 (mg/GAE/g), which are maximum and acceptable range values as compared to the other three composite flours and the control group flour. PPWF3 is used as a partial replacement ratio for wheat flour due to its high phenolic content, vitamin C content, and richness in fibers. This composite flour is used to make bread dough, and two samples, G1 and G2, are made, out of which G2 offers better nutritional, functional, and sensory evaluations in comparison with refined wheat bread, which is taken as a control group. Thus, such utilization of food waste in bread making can generate value from waste and improve the nutritional attributes of bread, which may improve an individual’s health.

Published: August 2023

Generalized progressive hybrid censoring approaches have been developed to reduce test time and cost. This paper investigates the difficulties associated with estimating the unobserved model parameters and the reliability time functions of the Kavya Manoharan Kumaraswamy (KMKu) distribution based on generalized type-II progressive hybrid censoring using classical and Bayesian estimation techniques. The frequentist estimators’ normal approximations are also used to construct the appropriate estimated confidence intervals for the unknown parameter model. Under symmetrical squared error loss, independent gamma conjugate priors are used to produce the Bayesian estimators. The Bayesian estimators and associated highest posterior density intervals cannot be derived analytically since the joint likelihood function is provided in a complicated form. However, they may be evaluated using Monte Carlo Markov chain (MCMC) techniques. Out of all the censoring choices, the best one is selected using four optimality criteria.

Published: August 2023

The research describes an effective deep learning-based, data-centric approach for diagnosing autism spectrum disorder from facial images. To classify ASD and non-ASD subjects, this method requires training a convolutional neural network using the facial image dataset. As a part of the data-centric approach, this research applies pre-processing and synthesizing of the training dataset. The trained model is subsequently evaluated on an independent test set in order to assess the performance matrices of various data-centric approaches. The results reveal that the proposed method that simultaneously applies the pre-processing and augmentation approach on the training dataset outperforms the recent works, achieving excellent 98.9% prediction accuracy, sensitivity, and specificity while having 99.9% AUC. This work enhances the clarity and comprehensibility of the algorithm by integrating explainable AI techniques, providing clinicians with valuable and interpretable insights into the decision-making process of the ASD diagnosis model.

Although some epidemiological studies have identified the associations between exposure to organophosphate pesticides (Ops) and respiratory diseases, diabetes mellitus (DM), and cardiovascular diseases (CVDs), controversial results still exist. In this review and meta-analysis, we aimed to investigate the overall pooled effect estimates and the possible mechanisms of the relationship between OP exposure and adverse health outcomes. In this study, Web of Science, PubMed, Embase, OVID, and the Cochrane Library were systematically searched until September 2022. Nineteen observational studies that focused on the general population or occupational populations examined the associations between OP exposure and respiratory diseases, DM, and CVD were included. Based on the overall pooled results, a significantly positive association was observed between OP exposure and respiratory diseases (OR: 1.12, 95% CI: 1.06–1.19). A significant link was also observed between various individual species of OP exposure and respiratory diseases, with an OR value of 1.11 (95% CI: 1.05–1.18). In particular, there was a significant association of OPs with wheezing and asthma, with OR values of 1.19 (95% CI: 1.08–1.31) and 1.13 (95% CI: 1.05–1.22), respectively. In addition, a significant association was also observed between OP exposure and DM (OR: 1.18, 95% CI: 1.07–1.29). However, no significant association was observed between OP exposure and CVD (OR: 1.00, 95% CI: 0.94–1.05). Exposure to OPs was associated with a significantly increased risk of respiratory diseases and DM, but there was no evidence of a significant association between OP exposure and CVD. Considering the moderate strength of the results, further evidence is needed to confirm these associations.

Published: August 2023

Kashin–Beck disease (KBD) is a multifactorial endemic disease that only occurs in specific Asian areas. Mycotoxin contamination, especially from the Fusarium spp., has been considered as one of the environmental risk factors that could provoke chondrocyte and cartilage damage. This study aimed to investigate whether new mycotoxins could be identified in KBD-endemic regions as a potential KBD risk factor. This was investigated on 292 barley samples collected in Tibet during 2009–2016 and 19 wheat samples collected in Inner Mongolia in 2006, as control, from KBD-endemic and non-endemic areas. The LC-HRMS(/MS) data, obtained by a general mycotoxin extraction technic, were interpreted by both untargeted metabolomics and molecular networks, allowing us to identify a discriminating compound, enniatin B, a mycotoxin produced by some Fusarium spp. The presence of Fusarium spp. DNA was detected in KBD-endemic area barley samples. Further studies are required to investigate the role of this mycotoxin in KBD development in vivo.
Classical Evolution without Evolution
Authors: Vedral Vlatko
Published: August 2023

The well-known argument of Page and Wootters demonstrates how to “derive" the usual quantum dynamics of a subsystem in a global state which is an eigenstate of the total Hamiltonian. I show how the same argument can be made in classical physics by using a formalism that closely resembles the quantum one. This is not surprising, since the Hamilton–Jacobi formulation of classical dynamics is precisely motivated by the logic of timeless dynamics. Ultimately, the key to obtaining dynamics without dynamics is the principle of energy conservation which leads to correlations between times pertaining to different subsystems. The same can, of course, be said about all other conserved quantities, and we show how to address this problem in its full generality so as to realise rotation without rotation, translation without translation and so on. The classical and quantum interpretations do, however, have one major difference and this is the Church of the Higher Hilbert Space interpretation of mixtures, which only exists in quantum physics. We discuss a few consequences of this point.

This study aims at examining the effects of an almost Ricci–Bourguignon soliton structure on the base and fiber factor manifolds of a doubly warped product manifold. First, a number of preconditions and sufficiency criteria for an almost Ricci–Bourguignon soliton doubly warped product are addressed. Additionally, an almost Ricci–Bourguignon soliton on doubly warped product manifolds admitting a conformal vector field is taken into consideration. Finally, how the almost Ricci–Bourguignon soliton behaves in doubly warped product space–times is examined.
Influenza A Virus Infection Alters Lipid Packing and Surface Electrostatic Potential of the Host Plasma Membrane
Authors: Petrich Annett , Chiantia Salvatore
Published: August 2023

The pathogenesis of influenza A viruses (IAVs) is influenced by several factors, including IAV strain origin and reassortment, tissue tropism and host type. While such factors were mostly investigated in the context of virus entry, fusion and replication, little is known about the viral-induced changes to the host lipid membranes which might be relevant in the context of virion assembly. In this work, we applied several biophysical fluorescence microscope techniques (i.e., Förster energy resonance transfer, generalized polarization imaging and scanning fluorescence correlation spectroscopy) to quantify the effect of infection by two IAV strains of different origin on the plasma membrane (PM) of avian and human cell lines. We found that IAV infection affects the membrane charge of the inner leaflet of the PM. Moreover, we showed that IAV infection impacts lipid–lipid interactions by decreasing membrane fluidity and increasing lipid packing. Because of such alterations, diffusive dynamics of membrane-associated proteins are hindered. Taken together, our results indicate that the infection of avian and human cell lines with IAV strains of different origins had similar effects on the biophysical properties of the PM.

Congenital Zika Syndrome (CZS) is associated with an increased risk of microcephaly in affected children. This study investigated the peripheral dysregulation of immune mediators in children with microcephaly due to CZS. Gene expression quantified by qPCR in whole blood samples showed an increase in IFNγ and IL-13 transcripts in children affected with microcephaly compared to the control group. The microcephaly group exhibited significantly decreased CCL2 and CXCL8 levels in serum, quantified by CBA assay. An allergic profile questionnaire revealed a high prevalence of allergies in the microcephaly group. In accordance, elevated serum IgE level measured by the Proquantum Immunoassay was observed in children affected with microcephaly compared to the control group. Altogether, these findings show a persistent systemic inflammation in children with microcephaly due to CZS and suggest a possible impairment in leukocyte migration caused by low production of CCL2 and CXCL8, in addition to high levels of IgE associated with high prevalence of allergies. The dysregulation of inflammatory genes and chemokines underscores the importance of understanding the immunological characteristics of CZS. Further investigation into the long-term consequences of systemic inflammation in these children is crucial for developing appropriate therapeutic strategies and tailored vaccination protocols.

Background: HIV infection causes neuroinflammation and immune activation (NIIA) and systemic inflammation and immune activation (SIIA), which in turn drive neurodegeneration (ND). Cross-sectionally, higher levels of NIIA biomarkers correlate with increased biomarkers of ND. A more convincing confirmation would be a longitudinal demonstration. Methods: PWH in the US multisite CHARTER Aging project were assessed at a baseline visit and after 12 years using standardized evaluations. We measured a panel of 14 biomarkers of NIIA, SIIA, and ND in plasma and CSF at two time points and calculated changes from baseline to the 12-year visit. Factor analysis yielded simplified indices of NIIA, SIIA, and ND. Results: The CSF NIIA factor analysis yielded Factor1 loading on soluble tumor necrosis factor type-2 (sTNFR-II) and neopterin, and Factor2, loading on MCP1, soluble CD14, and IL-6. The SIIA factor analysis yielded Factor1 loading on CRP, D-dimer, and Neopterin; Factor2 loading on sTNFR-II. The ND analysis yielded Factor1 loading on Phosphorylated tau (p-tau) and Aβ42; Factor2 loading on NFL. NIIA Factor1, but not Factor2, correlated with increases in CSF NFL (r = 0.370, p = 0.0002). Conclusions: Increases in NIIA and SIIA in PWH were associated with corresponding increases in ND, suggesting that reducing neuro/systemic inflammation might slow or reverse neurodegeneration.

Severe acute respiratory syndrome coronavirus (SARS-CoV)-2 enters the host by infecting nasal ciliated cells. Then, the virus can spread towards the oropharyngeal cavity and the pulmonary tissues. The antiviral adaptive immunity is promptly induced in response to the virus’s detection, with virus-specific T-lymphocytes appearing before antiviral antibodies. Both the breadth and potency of antiviral CD8+ T-cell immunity have a key role in containing viral spread and disease severity. Current anti-SARS-CoV-2 vaccines do not impede the virus’s replication in the upper respiratory tract, and there is consensus on the fact that the best potency of the antiviral immune response in both blood and the upper respiratory tract can be reached upon infection in vaccinees (i.e., breakthrough infection). However, whether the antiviral CD8+ T-cells developing in response to the breakthrough infection in the upper respiratory tract diffuse to the lungs is also still largely unknown. To fill the gap, we checked the CD8+ T-cell immunity elicited after infection of K18-hACE2 transgenic mice both at 3 weeks and 3 months after anti-spike vaccination. Virus-specific CD8+ T-cell immunity was monitored in both blood and the lungs before and after infection. By investigating the de novo generation of the CD8+ T-cells specific for SARS-CoV-2 viral proteins, we found that both membrane (M) and/or nucleocapsid (N)-specific CD8+ T-cells were induced at comparable levels in the blood of both unvaccinated and vaccinated mice. Conversely, N-specific CD8+ T-cells were readily found in the lungs of the control mice but were either rare or absent in those of vaccinated mice. These results support the idea that the hybrid cell immunity developing after asymptomatic/mild breakthrough infection strengthens the antiviral cell immunity in the lungs only marginally, implying that the direct exposition of viral antigens is required for the induction of an efficient antiviral cell immunity in the lungs.

Adherence to vaccination recommendations is a challenge for national immunization programs. We quantified adherence to COVID-19 vaccination recommendations in people with substance use disorders (SUDs) attending an outpatient addiction center in Rome, Italy; we investigated the determinants of adherence, and also analyzed patient risk perception and compliance with preventive measures. A multivariable logistic regression model identified predictors of adherence to vaccination recommendations, with statistical validity tested by estimating adjusted odds ratios (aORs) and 95% confidence intervals (CIs). From December 2021 to January 2022, 200 SUD patients completed a questionnaire, 80% of whom reported being vaccinated against SARS-CoV-2 (minimum one dose). Negative predictors of vaccine uptake included being non-Italian (aOR: 0.36, 95% CI: 0.13–0.97), having coexisting comorbidities (aOR: 0.35, 95% CI: 0.13–0.95), and previous use of heroin (aOR: 0.24, 95% CI: 0.08–0.71). No difference was found for cocaine use, demographic characteristics, previous COVID-19 infection, methadone therapy, or compliance with preventive measures. Major reasons for non-adherence to vaccination recommendations were fear of side effects, insufficient recognition of the importance of vaccination, bureaucratic issues, and lack of trust in the authorities. Given their vulnerability, additional efforts are needed to facilitate access to vaccination for people with SUDs, and to limit disinformation around vaccines..

The article discusses the current international experience of integrating various aquaculture projects into the infrastructure of the fuel and energy complex. Against the background of the active growth in the production of aquaculture products, there is a tendency for the multipurpose use of energy sector facilities (oil platforms, wind farms, etc.) to obtain valuable aquaculture products both during their operation and after the completion of the project period of use. The specifics of the production and assortment of aquaculture facilities and farming methods in different regions of the world have been identified, which determined the features of the integration of aquaculture into fuel and energy facilities. The most common and has been used for many decades in many countries of the world is the cultivation of aquaculture facilities on the recycled water of thermal power plants and reservoirs of hydroelectric power plants. In the European region, there is an active use of offshore platforms for the extraction of hydrocarbons with simultaneous agricultural, aquaculture, scientific activities and the production of electricity through the installation of wind and wave turbines. Oxygen and hydrogen production is organized on some platforms. In North America, projects of hybrid systems “food-energy-water” are being developed using aquavoltaics technology, which allows maintaining the aquatic environment in optimal condition. Fish farming is combined with the cultivation of crustaceans and shellfish, oil platforms are often repurposed into artificial reefs. A patented project of an integrated floating system consisting of four vertical-axial wind turbines connected to a single system with a solar battery and a floating base for the placement of aquaculture facilities is being implemented in Asia. The development of such projects, in addition to the pronounced positive economic effect, also contributes to improving the level of food security of the regions. The use of engineering structures and other infrastructure facilities as new locations and substrates for the cultivation and free habitat of various hydrobionts can significantly reduce the negative impact of the fuel and energy industry on the environment.

The beginning of the study of the raw material base and features of the biology of the crustacean Artemia Leach, 1819 is associated with the prospect of using cysts as a starter food in aqua and sea culture. Food from Artemia cysts is used in the cultivation of 85% of marine organisms. Numerous hypersaline lakes of the Altai Territory are of particular interest for the industrial extraction (catch) of a valuable bioresource, the morphometric features of which, salinity and light regime provide a high level of their bioproductivity. This article presents the results of a morphometric study of the crustacean Artemia in the hypersaline lake Kulundinskoe for 2020–2021. Due to the increase in the general level of moisture in the territory, Lake Kulundinskoye tends to decrease in mineralization. In this regard, there are changes in the catch (production) of the main commercial resource — Artemia (at the stage of cysts), and the biota is replenished with brackish-water species. Under conditions of reduced water mineralization, crustaceans show a decrease in the values of morphometric parameters. By 2021, during the study, an increase in morphometric indicators was found due to an increase in mineralization from 70 to 90 g/l. Based on the studied main plastic (14) and meristic (2) features of the Artemia crustacean in the hyperhaline lake Kulundinskoe and using correlation analysis, the dependence of the parameters of morphometric measurements of female brine shrimp was studied. Desalination of Lake Kulundinskoe was observed in 2020–2021, in connection with which the biological numerical characteristics of the artemia branchiopods are given.

The northern part of the Agrakhan Bay (Northern Agrakhan) has an important fishery importance in the Tersko-Caspian region of the Dagestan River, being a buffer zone where fresh and salt waters mix, therefore it plays a peculiar role of a receiving water body for passable and semipassable fish species migrating to spawning and wintering in the middle and lower reaches of the Terek River. Formation of stocks of commercial fish species in this part of the bay is currently taking place under conditions of reduced efficiency of natural reproduction, which is determined by the conditions of the hydrological and hydrochemical regime. In recent years, anthropogenic factors have caused profound negative changes in the structure of ichthyofauna in the Agrakhan Bay, and the water fishes of the lake-river complex began to dominate and the commercially valuable fish species of passage and semi-passage fish species began to decrease. Studying the dynamics of the number of recorded juveniles of commercial fish species allows not only to assess the efficiency of their reproduction, but also to determine the main causes affecting the reduction or increase in the stocks of various populations. The performed studies allowed to analyze the dynamics of changes in the number of recorded juveniles of commercial fish species that occurred over the last 5 and 10 years. It was confirmed that at present in the bay’s reservoirs low-value fish species are well adapted to the changed unfavorable conditions, as evidenced by the results of reproduction — the number of juvenile silver carp, redfish, perch and gouster increases from year to year. At the same time, against the background of unfavorable hydrological and hydrochemical regime and increased overgrowth of the bay, the migration activity of producers of passable and semipassable species decreases, leading to deterioration of fish reproduction results, which is confirmed by a decrease in the number of recorded juveniles of valuable species: kutum, redfish, vobla, catfish, pike, etc.
Bone health assessment in adults with fragility fracture risk factors between 2002–2014: a retrospective cohort study
Authors: Pradhan Anup Bahadur , Nicholls Elaine , Edwards John James , Welsh Victoria , Paskins Zoe
Published: August 2023

Background

Lifetime risk of fragility fractures is 50% in post-menopausal women and 20% in men aged >50 years. Identifying people at high risk facilitates early intervention and reduction of biopsychosocial morbidity associated with these fractures.

Aim

To explore if bone health assessment (BHA) rates differ between women and men aged ≥50 years with fragility fracture risk factors.

Design & setting

A primary care-based cohort study in North Staffordshire, UK.

Method

Patients were identified from the Consultations in Primary Care Archive (CiPCA) database between 2002 and 2014 with one or more fragility fracture risk factors (previous fractures, falls, and prolonged steroid use). Evaluation of BHA within 12 months of presentation of the first risk factor was carried out by searching for codes for fracture risk assessment tools (FRAX and QFracture), bone density measurement, specialist service referral, or if bone-protection medication was started.

Results

A total of 15 581 patients with risk factors were identified; men represented 40.4% of the cohort. The study found 1172 (7.5%) had BHA performed within 1 year of presentation, and 8.9% of women and 5.5% of men had BHAs, which was found with strong statistical evidence (χ2= 59.88,P= 1 × 10–14). This relationship prevailed after adjusting for other covariates, such as comorbidity and number of consultations, with an odds ratio of 1.25 (95% confidence interval [CI] = 1.08 to 1.43).

Conclusion

This study has shown that rates of BHA were generally low and even lower in men compared with women. Primary care clinicians should be alert to fragility fracture risk factors in both men and women to enable early assessment and intervention.

The primary objective of this study was to enhance the community's understanding and awareness of landslide risks and mitigation strategies by employing Geographic Information Systems (GIS) to identify landslide-prone areas in the Magetan District, East Java. The initiative unfolded in several stages, which included: (1) emphasizing the importance of mapping areas susceptible to landslides; (2) consolidating data through satellite image analysis and GIS; (3) developing GIS-based maps that depict landslide-prone areas; and (4) circulating these maps among the local community and governing bodies. In conclusion, this study demonstrates that a participatory approach, combined with advanced technologies such as GIS, can play a pivotal role in disaster mitigation. Early identification of landslide risks and appropriate mitigation strategies using GIS and community education can significantly enhance community preparedness and resilience to landslides. The potential applicability of this method to other regions with similar topographical and geological conditions underscores its relevance in improving community readiness and resilience against landslide disasters.

Enerji krizleri, fosil yakıtların yakın gelecekte tükenecek olması ve sera gazı etkisi dünyanın en büyük sorunları arasında yer almaktadır. Bu sorunlara çözüm noktasında güneş enerjisi teknolojileri ön plana çıkmaktadır. 3. nesil güneş pili teknolojileri arasında yer alan boya duyarlı güneş pilleri (BDGP) üzerinde yoğun araştırmalar yapılmaktadır. BDGP’lerin verimleri silisyum tabanlı güneş pillerine kıyasla daha düşük olmasına rağmen hassaslaştırıcı boyada yapılacak değişikliklerle bu hücrelerin performansları geliştirilebilir. Bu çalışmada acı meyan (Sophora alopecuroides) bitkisinin çiçek, tohum ve yaprak kısımlarından ekstrakte edilmiş boyalarla duyarlılaştırılmış BDGP’lerin fotovoltaik performansları araştırıldı. Fotoanot katmanı oluşturan titanyum dioksit’in (TiO2) minerolojik ve morfolojik analizleri X-ışını difraksiyonu (XRD) ve taramalı elektron mikroskobu (SEM) ile gerçekleştirildi. XRD sonuçları TiO2’nin anataz fazını ve kristal yapısını doğruladı. SEM görüntüleri birbirine sıkıca paketlenmiş mikro kürecik yapının varlığını ortaya çıkardı. Üretilen BDGP’ler arasında en yüksek hücre verimini 0.057 ile fotoanodu yaprak boyasıyla duyarlılaştırılmış hücre gösterdi.

Authors: Da Silva Rodrigues Charles Ysaacc
Published: August 2023

La Hidrocefalia de Presión Normal (HPN) por tumoración metastásica es una alteración neurológica muy poco común. La HPN se caracteriza por un exceso de líquido cefalorraquídeo acumulado en las cavidades ventriculares, siendo que en estos casos se produce por obstrucción metastásica. El propósito fue identificar y analizar los cambios neuropsicológicos antes y después de la colocación de un sistema de derivación ventriculoperitoneal. Se consideró apenas un participante para este estudio de caso, un hombre con 77 años residente en la ciudad de Lisboa. Se aplicó un screening constituido por diversas subpruebas de la WISC, figura compleja de Rey, EADS, 16PF-5 y una entrevista clínica. En la evaluación preoperatoria se verificaron déficits neuropsicológicos y cambios de la regulación emocional significativos. Una vez colocada la derivación apenas persisten los cambios en la memoria visoespacial y sintomatología depresiva. La estimulación natural presentó mejoras, sin embargo, la memoria debe ser rehabilitada y la depresión tratada para minimizar el daño.

In order to improve the opener of the seeder and its lightweight structure, a new type of opener is designed. The overall structure and working principle of a single-ditch double-row opener are analyzed, and the structural parameters of machete cutting soil and the soil guide board are designed and optimized. Using the penetration angle of machete cutting soil and the included angle of the soil guide board as test factors, field experiments were conducted. As the test indexes, the working resistance, the sowing coefficient of variation, and the depth coefficient of variation were used to analyze the effect of the opener. The results showed that in terms of working resistance, the penetration angle of the machete cutting edge and the included angle of the soil guide board were extremely significant, and the included angle was greater than the penetration angle regarding the influence degree. In terms of the sowing coefficient of variation, the penetration angle was significant, and the included angle was extremely significant. Regarding the depth coefficient of variation, the penetration angle was extremely significant, and the included angle of the guide soil board was significant. Based on the optimization analysis by using the Design Expert 8.0.6, it is found that the performance of the opener is optimal when the penetration angle and the included angle are 50.03° and 42.36°, respectively. The working resistance, the sowing coefficient of variation, and the depth coefficient of variation are 61.47N, 6.49% and 4.22%, respectively. After verification, the results are basically consistent, and the seeding and trenching performance meets the agronomic requirements. This study can provide a basis and technical reference for the design and development of the ditching technology and opener.
