Parametric analysis for the determination of solar collector and hot water tank capacity in solar-assisted heating systems
Authors: HAYDARASLAN Ersin
Published: May 2023

In this study, a study was carried out on integrating solar assisted systems into heating systems in a building. For the study, an existing building was modeled with the DesignBuilder building energy simulation program. The scenarios were created on the model to determine the number of solar collectors and the capacity of the water tank used in solar assisted heating systems. The primary energy consumption, global costs and payback periods of the scenarios created were obtained by parametric analysis. According to the results obtained, the solution that reduces primary energy consumption the most is SYS20, the solution that reduces the global cost the most is SYS1 and the optimum solution is SYS7. Considering the payback periods, SYS1 was determined as the most appropriate solution to be applied in the study since it was the solution with the minimum payback period. At the end of the study, it was seen that primary energy savings could be reduced by up to 47% with solar energy assisted heating system. Thanks to the study, a reference source for the number of solar collectors and water tank capacity selection in Isparta and provinces with similar climates has been created.

Published: May 2023

Austenitic manganese steel (AMS) is widely used in the mineral and mining industry under high workload condition due to its remarkable work-hardening capacity under impact. However, AMS typically has an austenitic matrix with carbides precipitated resulting in low hardness and brittle properties, which impaired its wear performance. In this study, cold deformation followed by flash annealing were conducted to improve the mechanical behavior of AMS. The experimental was carried out by solution treatment (ST), cold rolling (CR) with deformation degrees of 10% and 20%, and flash annealing (FA) at 915°C with holding times of 90 and 150 seconds. The microstructure evolution and mechanical behavior were studied. The ST produced a completely austenitic microstructure which was free of carbide, resulting in a decrease in strength and hardness, as well as improved ductility. After cold deformation, both of strength and hardness were substantially improved, followed by loss in ductility. Optical microstructures reveal the formation of deformation twin (DT) and annealing twin (AT) after cold deformed. Higher intensity of DT results in AMS with considerable strength and hardness but decrease in ductility. After FA process, cold deformed structures undergo microstructural restoration, which manifests by recovery stage at 90 s and recrystallisation stage at 150 s annealing time. At the same FA time, higher degree of deformation led to increase the hardness, while at the same degree of strain, longer annealing time led to a decrease of hardness. Moreover, both of higher degree of strain and longer annealing time during flash annealing were contributed to grain refinement, even though did not affected to the increase of tensile and hardness. In addition, 20% cold rolling followed by 150 s annealing time (CR20FA150) could be considered as an effective method to obtain the most optimum combination of strength and ductility with finer grain.

Published: May 2023

Background and objectives: Basal cell carcinoma is the commonest malignancy among all malignancies of the body. Sun exposure plays an important role in its pathogenesis. Basal cell carcinoma usually is localized and metastasizes rarely. Dermatoscopy is a new non-invasive surface microscopic examination of the skin. It is proven to play a significant role in the early diagnosis of BCC. The aim of the study is to evaluate the dermatoscopic features of basal cell carcinoma lesions. Methods: One hundred and seventy lesions on the head and neck of patients were suspected of BCC dermatoscopically and included in the study. Biopsies of the lesions were sent 140 for histopathological confirmation. Dermatoscopic pictures of each lesion are saved as pictures through a camera adapted to the dermatoscopy. Data and dermatoscopic pictures were evaluated and analyzed statistically. Results: Diagnosis of basal cell carcinoma was confirmed for 163 lesions out of 134 patients with head and neck BCC lesions. The majority of patients had photo type III (75.3%). The most common clinical type was ulcerative (74 lesions, 45.4%). Pigmented lesions were 107 (65.6%) basal cell carcinoma lesions. The sensitivity of dermatoscopic diagnosis of BCC was 95.8%. Eight dermatoscopic features were observed in the lesions. The most common dermatoscopic finding was vascular (126, 77, 3%) and the most common vascular feature was arborizing blood vessels. Conclusions: Dermatoscopy is a useful noninvasive visual aid in the diagnosis of basal cell carcinoma and its sensitivity is usually above 95%. Histopathology of basal cell carcinoma may remain in the future as a tool for control of its treatment only.

Background and objectives: The proximity of inferior alveolar canal to roots of lower third molar is one of the serious challenges facing surgeons during extraction of that tooth. There are different types of this relation, mainly: away, in direct contact and crossing the canal. The aim is to evaluate the relation between roots of lower third molar and inferior alveolar canal, in Winter classification of impaction of impaction to decide whether to do surgery or to ask for Cone Beam Computed Tomography first. Methods:Orthopantomographs f 206 cases were retrospectively evaluated: the presence of impaction; applying Winter classification; studying roots, numbers; and their relation to the canal (away from, in direct contact and crossing). Results: One hundred and twenty-four cases were with lower third molar impaction; mean age (29.5 ± 6.2); mesioangular was the most common type of impaction. In general, 24 (19.5%) cases were away; 51 (40.5%) cases were with a direct contact; 49 (39.5%) cases were crossing the canal. In mesioangular im- paction the common relations were in direct contact and crossing the canal. There was large difference in prevalence of single-rooted and two-rooted teeth, with being two-rooted the common one, there were no significant differences in their relation to the canal. Two divergent rooted teeth majority were in direct contact with the canal. Conclusions: Our results showed that just 19.7%, regarding the relation to inferior alveolar canal are safe to do surgery without radio- graph, the rest has the risk of endangering the nerve and 40% needs computed tomography.

Published: May 2023

Background: Health literacy has been defined as the ability to gain access to, understand, and use information in ways which promote and maintain good health. The significance of mental health literacy (MHL)is evolving as a modifiable contributing factor to mental health. This study was undertaken to assess the awareness and attitudes of Afghans on mental disorders.
Methods: A cross-sectional survey was administered in August 2022 among Afghans (N=768) living in the Herat province of Afghanistan. The survey examined knowledge and attitude of participants on mental disorders.
Results: Generally, most of the participants (99.1%) had poor mental health literacy. 99.4% of participants with an age range of 36-90 years had poor mental health literacy. Almost three-quarter of the participants had poor knowledge of the ability to recognize disorders (72.5%). Less than one-thirds of the participants had good knowledge of where to seek information (29.4%).
Conclusion: Mental health literacy rate was found very low among Afghan population. Socio-economic variables found significantly associated with MHL was educational level, economic status, and employment status. Considering the high prevalence of mental disorders in Afghanistan, the government and related non-governmental organizations should implement awareness campaign to increase the knowledge of Afghan people on mental disorders.

The recognition of agroecological-silvopastoral practices has been interesting for many government agencies and rural projects in Mexico in recent years. In southeastern Mexico, the program Sustainable Rural Development in Biological Corridors (DRSCB) in the Lacandon Jungle of Chiapas, Mexico, implemented various actions to search for a more friendly livestock with the conservation of biodiversity and improve agricultural production. The objective of this research was to identify the levels of technological livestock adoption in Tzeltal communities with cattle activities. Likewise, socio-environmental barriers were identified that limited this initiative of the DRSCB. The contributions of this research can contribute to design and search for participatory alternatives for the implementation of a more sustainable livestock.

Evaluation of the reproductive tract development (RTD) is a criterion rarely used when heifers are included in estrous synchronization programs. The objective was to determine the effect of RTD and hormonal treatment (HT) on estrous and ovarian activity in Bos indicus heifers under humid tropical conditions. Twenty-four Bos indicus heifer were synchronized using a bovine intravaginal device (BID), divided according to RTD (immature or mature) and HT (estradiol cypionate or estradiol benzoate). Estrous was recorded from 24 to 60 h after BID removal. Follicular monitoring was evaluated by ultrasound every 12 h from BID removal until ovulation. Blood samples were taken on day 0, 3, 8 and 15 post BID removal to estimate progesterone (P4) concentration. Data were analyzed by analysis of variance and logistic regression procedures. There was no interaction between factors (P > 0.05). The highest percentage of estrous was found in heifers with mature RTD (91.7%, P < 0.05). The interval BID withdrawal to estrous (50.0±2.6 h), the proportion of heifers that ovulated (100%), the interval BID withdrawal-ovulation (75.0±2.1 h), and the time between onset of estrous and ovulation (24.5±2.2 h) were similar between immature and mature reproductive tracts and between HT. In addition, the growth of dominant follicles and P4 concentration were similar for both study group. In conclusion, RTD had effect on estrous behavior, however, ovulation, diameter of dominant follicle and plasma P4 concentration of both groups (RTD and HT) were similar on estrous synchronization, in Bos indicus heifers under humid tropical conditions.
INFILTRATION CHARACTERISTICS OF A TYPIC HAPLUSTULT UNDER DIVERSE TILLAGE PRACTICES AND COVER CROPS IN NORTHERN GUINEA SAVANNA OF NIGERIA

Published: May 2023

Soil tillage and vegetation cover impact a great deal on hydrological processes in soil. However, there exist a dearth of literature on the extent of these effects in semi-arid Nigeria. This study investigated the effect of tillage practices (no-till, (NT) reduced till (RT) and conventional tillage (CT)) and cover crops (Centrosema pascuorum (CP), Macrotyloma uniflorum (MU), Glycine max (GM), Cucurbita maxima (CM) and no cover crop (bare) as control) on soil water infiltration rate and characteristics. A double ring infiltrometer was used to carryout infiltration study of soils under the aforementioned tillage practices and cover crops. Data obtained were used to calculate infiltration rate and these were also fitted into the Philip and Kostiakov’s models. The quality of adjustment of the models was verified by a chi square and T test, coefficient of determination (r2) and standard deviation. Result revealed higher infiltration rate in soil under conservation tillage (NT and RT) due to soil pores continuity, than in the CT where the pores had been disrupted by tillage implement. Similarly, the use of any of the evaluated cover crops improved water infiltration better than the bare soil with no cover crop. Conservation tillage system (RT and NT) favoured better soil infiltration rate by 41.25% and 29.53% respectively more than conventional tillage system. Plots with cover crops had 65.27%, 59.46%, 54.88% and 18.9% higher soil water infiltration rate in CP, MU, GM and CM treatments respectively than the bare (no cover crop) treatment. Both Kostiakov and Philip’s model were suitable for predicting the first one-minute infiltration rate. However, Kostiakov’s equation showed superior performance over Philip’s equation, in determining cumulative infiltration, this was evident from the lower standard deviation and CV values of Kostiakov’s parameters. In addition to the general non-significance differences obtained between measured and Kostiakov’s predicted infiltration values as revealed by Chi square test.

The effects of Bacillus thuringiensis culture supernatants and their derived products were evaluated on whitefly Bemisia tabaci and its parasitoid Eretmocerus eremicus. Evaluated variables on B. tabaci included adult repellence, oviposition deterrence and nymphal mortality. The most active products were evaluated on mortality of E. eremicus. Residual solid of strain ITCBT62 supernatant showed significant effects on adult repellence (RI, 0.42) and oviposition deterrence (ODI, -70.1). Residual solid of strain ITCBT62 supernatant and ethanol extract of strain ITCBT61 supernatant caused higher mortality of B. tabaci nymphs (53.8 % and 51.2 %, respectively). None of these supernatant derived products had toxic effects on the parasitoid E. eremicus. The analysis of ethanol extract of strain ITCBT61 supernatant by liquid chromatography/high resolution mass spectrometry (LC-HRMS) showed the presence of various compounds, with one particularly abundant metabolite of molecular formula C15H20N2O, which has not been previously reported as product of the liquid culture of B. thuringiensis.

Mucuna pruriens has been underexploited as a food source and nutraceutical due to its L-Dopa content, which is toxic. We examined the effect of detoxification methods on feed intake, behavior, and physiological parameters. Sixty Sprague-Dawley rats were randomly assigned to five treatments consisting of commercial chow or diets with undetoxified or detoxified Mucuna. Rats were housed in metabolic cages and feed intake was monitored. Animal behavior was video recorded using the Open field test. Upon necropsy, organ weights and blood were analyzed. Feed intake was not affected by dietary treatment. The total distance travelled in the Open field was reduced by Mucuna diets. Treatments did not affect most organ weights. Relative to control, feeding undetoxified Mucuna, suggests that detoxifying Mucuna prevented splenomegaly and monocytosis. Rats fed undetoxified Mucuna had less blood phosphorus than control, but those fed detoxified diets did not. Rats fed undetoxified Mucuna had less alkaline phosphatase than those fed detoxified diets and tended to be anemic. Feeding detoxified Mucuna prevented the splenomegaly and monocytosis associated with feeding undetoxified Mucuna. Therefore, detoxification improved the food safety of Mucuna, making it more widely usable as a source of nutrients and a nutraceutical.

Published: May 2023

To determine the species of agaves most used for the elaboration of artisanal mescal, as well as their productive attributes and availability, interviews with producers were conducted and a ranking matrix was obtained. The agaves with greater scores were: “arroqueño” (Agave americana L. var. oaxacensis Gentry); the “espadín” and the “coyote” (A. angustifolia Haw and A. americana L.) all with high yields, demand in the market, rooting among the producers, but scarce in the region. In a second group there was located the maguey “tobalá” (Agave potatorum Zucc) the most emblematic culturally speaking, with high demand in the region, but with a low yield; besides it is only found in the wild, so it is already scarce. In the last block the agaves found: were “mexicano” (Agave aff. rodacantha), “barril” (Agave rhodacantha Trel), “jabalí” and tobasiche (Agave karwinskii Zucc.). The maguey coyote (Agave americana L.) had the highest yield of mescal with 17.78 ml / kg / year, the maguey jabalí (Agave kerchovei Lem) had the lowest yield with 6.16 ml / kg / year, while the espadín (Agave angustifolia Haw) was in an intermediate position. The agaves that had a low yield, small boll size and medium local rooting were generally used by non-certified producers as fillings to complete production lots.

For the replanting of the sugarcane crop, plants produced from buds of different reserve sizes and from different positions on the stem are used, without up to now an optimum reserve and position size has been determined to obtain a quality plant. Therefore, five treatments were evaluated for nutritional reserve: T1 (short reserve), T2 (without reserve), T3 (half reserve), T4 (long basal reserve) and T5 (long reserve superior) and for the position a design was used 2x3 factorial (two cultivars: MEX69-290 and COLPOSCTMEX05-223 and three yolk positions: basal, middle and apical), the treatments were distributed in a completely randomized arrangement. The buds were sown in unicel vessels with a liter capacity and sifted sand was used as substrate. It was evaluated; emergency percentage, root length and plant height. The results indicate that the use of buds with different positions in the stem is possible to produce seedlings of good quality, since more than 50% of sprouting was obtained in both cultivars. The results on nutrient reserves showed that T3 had the longest root length (36.2 cm) and T1 had the highest plant height (61.4 cm), showing that there is no direct relationship between plant height and root length. To obtain a quality plant it is enough to use short buds or half reserve and any position. For the commercial production of plants, it is recommended to plant in substrates rich in nutrients.

Secondary tropical forests are largely dominated by small-diameter trees. Their contribution to the total stand productivity may be determinant for ecosystem functioning. However, the biomass contained in small-size trees is frequently ignored because they are rarely included in forest inventories, as well as due to the lack of biomass equations for such trees. The aim of this study was to generate specific biomass equations by tree structural components and total-tree biomass for 22 species (diameter at breast height-DBH ≤ 10 cm diameter) structurally important of secondary tropical forests in southeast Yucatán peninsula. The biomass equations were generated using two fitting approaches. First, using the additive approach where the biomass equations by structural tree components (stem, branches and foliage) were simultaneously fitted. Second, the tree-level approach where the total-tree biomass was independently fitted. We used DBH, total height (TH) and wood density (WD) as predictor variables during the fitting process. The performance of each total-tree biomass equation was compared to generalized biomass equations developed in other tropical forests. The variance explained of observed biomass across tree species were stem, 64% to 99%; branch, 24% to 95%; foliage, 35% to 94% for equations by structural tree components; while the explained variance for total tree biomass equations was between 94 to 99 %. The inclusion of TH and WD as predictor variables in the equation structure, significantly improved the goodness of fit statistics. These are the first equations developed for small-size tree species in secondary forests of Yucatán peninsula. We observed that generalized equations developed for other tropical forests, in some cases overestimated up to ~ 44.2% and in other cases underestimated up to ~ 48.4% the mean total-tree biomass. When we applied our equations to forest inventory data, they showed a better predicting performance than generalized equations. Therefore, they are reliable for estimating biomass of small-size tree species in similar forest types. Our equations could be used for biomass-carbon estimation in tropical secondary forests composed by high densities of small-size tree species; therefore, they are relevant within climate change contexts.

Background: Improvement of the Nigerian indigenous chickens is desirable because of its socioeconomic important. Objective: To estimate the heritability, genetic and phenotypic correlations among body weight, body length, wing length and shank length of the mating of heavy ecotype cocks with light ecotype hens of Nigerian indigenous chickens. Methodology: The mating design was such that one heavy ecotype cock mated with 10 light ecotype hens in twenty replicate pens. The mating produced 752 chicks from ten batches of hatch. The estimates of variance components were obtained from paternal half sib analysis using the average information restricted maximum likelihood of BLUPF90 family of programs. Results: The heritability of body weight ranged from 0.20 to 0.44 from 6 to 12 weeks of age. Similarly, the heritability of body length, wing length and shank length ranged from 0.39 to 0.63, 0.51 to 0.71 and 0.31 to 0.54 respectively from 6 to 12 weeks of age. The genetic correlations among the early growth traits measured were negative to positive in magnitude and ranged from -0.99 to 0.66 while the phenotypic correlations ranged from -0.15 to 0.91. Implication: The results imply that early growth traits of light and heavy ecotype Nigerian indigenous chicken could be improved through mass selection. Conclusion: It is concluded from this study that the heritability of early growth traits were moderate to high in magnitude and the genetic and phenotypic correlations mostly positive.

Singular Optimal Linear Quadratic Regulator of Switched Systems
Authors: Fu Lulu
Published: May 2023

In this paper, we will investigate the singular linear quadratic regulator (LQR) problem of switched linear system in finite time horizon. The proposed method is transforming into a switched LQR problem by adopting linear transformation. Next, we adopt an embedding transformation method to convert the switched LQR problem to a traditional optimal control problem, so the bang-bang-type solution of the embedded optimal control problem in finite time is the optimal solution to the switched LQR problem. The switching sequence of modes and the switching instants can be calculated by solving a closed-form optimal switching condition. The optimal state feedback control law is determined simultaneously. Then, by solving a sequence of Riccati equation, we find some conditions that ensure switched LQR problem can be convert to the singular LQR problem. Finally, a numerical example is presented to demonstrate the effectiveness of the proposed method.

Multi-Perspective Analysis of the Sustainable Transformation of Multinational Companies
Authors: Liu Ruichen
Published: May 2023

The sustainability transition has been defined as “a radical shift to a sustainable society” as a response to some of the ongoing issues facing the new mainstream economies. However, the importance of sustainable transition has been overlooked by many countries and large organisations. As climate change and energy scarcity become urgent, many large organisations are pursuing sustainable transformation to achieve low cost and resource reuse. A study of the existing literature reveals that the literature on the sustainable transformation of large organisations and multinational corporations is limited and not analysed more comprehensively. This paper aims to illustrate methods and recommendations for the sustainable transition of multinationals and to analyze the sustainable transition of multinationals using different theoretical factors and sustainability models. For example, the three pillars of sustainability, this section illustrates the operational and technological transformation of multinational companies; the 10 R’s of sustainability and value creation demonstrate the concepts that multinational companies focus on to meet their success criteria for sustainable transformation; and the importance of sustainable transition for multinational companies is also analyzed from the perspective of supply chain and corporate social responsibility. Meanwhile, links are made between these theories and models, indicating the importance of focusing on multiple dimensions for better accomplishing the sustainable transition.

With the continuous development of the economy and society, the demand for land space for human survival has also increased, which means that the pressure on ecosystem services has also been unprecedentedly high, leading to serious problems such as ecological environment deterioration and system function decline, resulting in fierce conflicts between ecological environment protection and human social development. Therefore, the relationship between ecosystem services and economic and social development has become a hot research topic in the field of land ecology. Jiaozuo City is also facing the problem of ecological degradation. In order to achieve coordinated development of ecology, society, and economy, this article analyzes the spatiotemporal changes in land use/cover in Jiaozuo City from 1995 to 2020. The InVEST model is used to evaluate four types of ecosystem services in Jiaozuo City: water production, carbon storage, soil conservation, and nutrient output; Summarize and summarize the spatiotemporal distribution characteristics and evolution laws of ecosystem services, and explore the trade-off and synergistic relationships between ecosystem service functions and their driving factors. The research results indicate that: (1) The main types of land use/cover in Jiaozuo City are arable land (64.5%), forest land (approximately 9.9%), grassland (1.1%), water area (0.6%), and construction land (23.8%). The changes in land use types are relatively small. (2) From 1995 to 2020, the biomass and spatial distribution evolution of the four ecosystem services in Jiaozuo City varied. There are significant interannual differences in water production services, and the spatial distribution of water production in the western region is lower than that in the eastern region. The southern region is lower than the northern region. The interannual variation of nutrient (phosphorus) output is relatively small, and the spatial distribution pattern varies greatly, showing a high and low value clustering distribution pattern. The interannual difference in soil conservation is relatively small. The interannual differences in carbon storage are small, and the annual spatial distribution is irregular. (3) Each ecosystem service is influenced by different natural and social influencing factors, and the contribution rate of natural factors is higher than that of social factors. There is a significant difference in the output capacity of ecosystem services among different land uses/covers, which directly affects the total amount and spatial distribution of ecosystem services. The ecological status of Jiaozuo City is worrying. In the future socio-economic development process, reasonable planning of land use should be carried out to vigorously ensure the parallel and healthy development of social economy and ecological environment.

Authors: Jia Boqiao
Published: May 2023

With the development of society, traditional and single art forms can no longer meet people’s needs, and different art forms have gradually broken down barriers. Just as different art forms combined to give birth to new forms of art, such as the combination of literature, dance, and music creating theater art. The combination of film and musical theater during the era of movies gave birth to musical films, which is a new branch in the field of art. Video games are an interactive and participatory digital medium, which not only allows players to enjoy the entertainment and interactive experience of the game itself but also provides them with a rich artistic experience. Through video games, players can come into contact with and understand different types of art, enhancing their recognition and understanding of art. With the development of the video game industry and the advancement of technology, video games have gradually integrated and carried other forms of art, enabling cross-media and cross-cultural dissemination of art through video games as a carrier. This study explores the essence and connotation of video games, providing support for their position and development in the field of art, promoting the diversification of the art field and cultural exchange. It can also provide useful ideas and references for professionals, scholars, and enthusiasts in the fields of culture and art.

Published: May 2023

The resolution of securities group disputes is a common problem faced by all securities markets in the world. Article 95 (3) of the new Securities Law provides a Chinese version of the solution to this problem. As a natural spokesperson for the interests of small and medium-sized investors, investor protection institutions are at the core of securities group litigation. In order to truly activate this system, we should do a good job in the top-level design of the rule system, clarify the substantive conditions and corresponding procedures for the initiation of litigation, accept cases with both group and public welfare, establish an efficient supervision mechanism for group members by establishing a representative committee of group members, and further reform the investor protection institutions, and open up the competition of investor protection institutions to better meet the actual needs.

Mushrooms are natural materials that spread in cosmopolitan manner. In this study, antimicrobial and antioxidant properties of wild mushroom Bovista nigrescens Pers were determined. In addition, the total phenolic contents and element levels of the mushroom were determined. The mushroom was extracted with ethanol and methanol in a soxhlet apparatus. The antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) were measured using Rel Assay Diagnostics (Mega Tıp/Türkiye) kits. The agar dilution technique was used to test for antimicrobial activity. To quantify total phenolic content, the Folin-Ciocalteu reagent was utilised. A device that uses atomic absorption to measure element concentrations was used. The results showed that the TAS value was the greatest in the ethanol extract. Methanol extract was found to have the highest values of both TOS and OSI. Ethanol extracts were shown to be effective against bacterial strains at concentrations of 50-200 μg/mL and against fungal strains at 100 μg/mL. The methanol extract was shown to be effective against bacteria at concentrations between 100 and 400 μg/mL, and against fungi at concentrations between 100 and 200 μg/mL. The ethanol extract and the methanol extract had total phenolic contents of 46.83±4.77 mg/g and 39.22±4.86 mg/g, respectively. Overall, element concentrations were determined to be consistent with what is reported in the literature. However, it was found that Pb content was rather high. Therefore, B. nigrescens was shown to possess antioxidant and antibacterial properties.
