Design, development, and analysis of a box type solar cooker with optimally reflecting side walls

A novel inclined sidewall box-type solar cooker is constructed, and its performance is evalu-ated. The Opto-geometrical design of the cooker was designed for Surat, a city in India. The design is modified by optimizing the inclination angles of the sidewalls so that an optimal thermal response may be generated by reflecting sun rays from the sidewalls, and the perfor-mance of the solar cooker is enhanced. The optimized sidewall angles due south, due north, due east, and due west are designed to be 67.30, 22.690, 35.440, and 35.440, respectively and side walls are made reflective with reflecting Aluminium sheets. The results are compared with a conventional cooker. The thermal performance of the newly built solar cooker was evaluated, and the merit F1 for no-load circumstances and the merit F2 for various loading conditions were determined. The results show that the maximum plate temperature, the figure of merit F1, and the maximum pot temperature of the newly developed solar cooker with optimally reflecting sidewalls during load test are higher than that of a conventional cooker. The max-imum plate temperature is found to be 760C and 650C in newly designed and conventional solar cookers, respectively. The temperatures are found to be about 16% more from 11:30 pm to 2:00 pm in the newly designed cooker compared to the conventional cooker. The maximum value of Figure of merit F1 is found to be 0.15 and 0.11 in newly designed and conventional solar cookers. The maximum value of Figure of merit F2 is found to be 0.59 and 0.30 in newly designed and conventional solar cookers. The maximum value of pot temperature is found to be 860C and 600C for newly designed and conventional solar cookers, respectively, during the load test, which is about 43% more in the newly designed cooker than the conventional cooker. The highest cooking temperature in the newly designed cooker was maintained at 90 0C for about 2 hours, and that in the conventional cooker was maintained at 60 0C for about 2 hours. In addition, the cooking test demonstrates that the food is thoroughly cooked in the newly built solar cooker, while it was discovered undercooked in the conventional cookerC thickness, respectively without heat recovery. The operating conditions and optimized geo-metric factors, based on result analysis and comparison, are discussed in detail.

Research and application of box type substation operation safety management and control system based on three-dimensional modeling and UWB positioning

This paper proposes a box type substation operation safety management and control system based on GIM modeling technology and UWB positioning technology to address the current challenges of personnel and vehicle control, single control methods, difficult information exchange, and blind spots in on-site substation operations. This system integrates safety control measures throughout the entire operation process of the substation before, during, and after operation, achieving closed-loop control of operation safety. Firstly, laser point cloud and power system GIM technology are used for three-dimensional modeling of substation environment and equipment. Then, UWB positioning technology is used for indoor positioning. Combined with various business systems such as substation work tickets and SCADA, the qualification review of station personnel and vehicles before substation operation is achieved, real-time monitoring of personnel status and movement trajectory during operation, and real-time monitoring of on-site environment after operation are achieved. The system has been deployed and applied to a 35kV box type substation in Guizhou, and through a period of actual operation, it has effectively controlled the operation site.

“Experiment Analysis of Box Type Solar Cooker with and without Thermal Energy Storage Medium”

Abstract: Energy plays a vital role for cooking purpose. This study is focused on the performance analysis of box type solar cooker at the climate conditions of Gwalior. Thermal energy storage materials provide better temperature and reducing cooking time as compared to without TES. In this thesis, two different types of TES material are used i.e. water and sand and the performance of solar cooker with TES and without TES are compared, the maxi mum temperature is attained by the solar cooker without TES was found 90.6oC when solar radiation was 1075 w/m2 while using sand and water as TES the maximum temperature was found 81.3°C and 69.4oC respectively when solar radiation was found very low 496 w/m2 and 365 w/m2 .It seems that where radiation is low and off-sunshine, TES material is used for attaining maximum temperature. The sand gains the temperature faster than the water but it needs to be moisture free. The advantage of using water is that even though there occurs a sudden fall in solar radiation, the water temperature remains the same for a long duration, which is not possible in case of cooker without thermal energy storage.

Research Progress and Prospect of Wave Attenuation Performance and Integration of Wave-Energy Converter of Floating Breakwater

A floating breakwater can significantly reduce the wave invasion of marine structures and provide a safe construction environment and service environment for wave attenuation protection for marine structures. With the development and utilization of marine resources, the application of floating breakwaters in engineering is becoming more and more important; research on integrated systems of a floating breakwater and wave-energy converter (WEC) is also valuable. However, existing research has not yet systematically improved the influencing factors of wave attenuation performance of floating breakwaters and the summary of the wave attenuation mechanism; there are few summaries about the integration of floating breakwaters and wave-energy converters. Therefore, the research progress on the wave attenuation performance and wave-energy integration of floating breakwaters is reviewed and summarized.

Secondly, the wave attenuation performance of three types of breakwaters and the research progress of floating breakwater-WEC integrated devices are discussed and reviewed. Finally, the problems to be solved in the study of various breakwaters and the key directions for future research are summarized. This review is helpful to deepen the cognition and understanding of wave attenuation performance of floating breakwater and floating breakwater-WEC integration devices, which can provide reference for the optimization research and engineering application of floating breakwaters.

A Projection Neural Network to Nonsmooth Constrained Pseudoconvex Optimization.

In this article, a single-layer projection neural network based on penalty function and differential inclusion is proposed to solve nonsmooth pseudoconvex optimization problems with linear equality and convex inequality constraints, and the bound constraints, such as box and sphere types, in inequality constraints are processed by projection operator. By introducing the Tikhonov-like regularization method, the proposed neural network no longer needs to calculate the exact penalty parameters. Under mild assumptions, by nonsmooth analysis, it is proved that the state solution of the proposed neural network is always bounded and globally exists, and enters the constrained feasible region in a finite time, and never escapes from this region again. Finally, the state solution converges to an optimal solution for the considered optimization problem. Compared with some other existing neural networks based on subgradients, this algorithm eliminates the dependence on the selection of the initial point, which is a neural network model with a simple structure and low calculation load. Three numerical experiments and two application examples are used to illustrate the global convergence and effectiveness of the proposed neural network.

Simulation study of a box type solar cooker for different locations

Solar cooker which relies on solar energy can be a viable alternative for the reduction of pollution during the combustion of biomass during the cooking process. The emission from biomass contains hydrocarbons as its major source. This simulation study of box type solar cooker performed using ANSYS Fluent version R1 2022 helps in optimizing the design of solar cooker to predict solar heat flux values for different locations such as Chennai, Vellore, Karur and Rameswaram for a particular day and particular time intervals such as 9 am, 12 pm, 2 pm, 5 pm. The proposed work further highlights the region where the solar cooker can be efficiently used by utilizing non-conventional energy sources for cooking process. In the simulation process, Discrete Transfer Radiation Model (DTRM) was used for tracking the solar radiation and solar calculator to predict the direct and diffuse solar irradiation for a particular day, by considering the latitude, longitude and Greenwich Mean Time (GMT) for specified locations. The specified geographical regions are plotted in a spatial map with solar radiation data obtained from Indian Meteorological Department (IMD) through ArcGIS geospatial techniques. The maximum solar heat flux values obtained at 12 pm, in the simulation results are 718 W/m2, 698 W/m2, 726 W/m2 and 720 W/m2, it is identified that among the four regions karur recorded the highest solar heat flux value of 726 W/m2. The minimum solar heat flux values at 5 pm are 215 W/m2, 202 W/m2, 265 W/m2 and 230 W/m2. Vellore was observed to have the minimum solar heat flux value of 202 W/m2. Solar radiation data obtained from the solar calculator and IMD radiation data were in good agreement with each other with a maximum error percentage of 2.36% because of the variation in the sunshine factor.

PREDICTION AND STUDY OF THE OCCURRENCE OF CERVICAL CANCER RECURRENCE

Cervical cancer has been found to have increased morbidity and mortality in women around the world. Despite complex treatment according to stratification, the risk of relapse is observed in up to 40% of patients Purpose of the study: - Improving the result of early diagnosis of recurrence of cervical cancer stump after complex treatment, by determining the value of the immune response by immunohistochemical markers in combination with the results of complex research methods Materials and methods: - The basis of the research work was a retrospective analysis of the results of the examination and complex treatment of 87 patients with cervical cancer who were treated and treated at the Republican Specialized Scientific and Practical Center of Oncology and Radiology of Uzbekistan, as well as in its Samarkand Regional Branch from 2012 to 2017. All patients underwent complex treatment of 4 courses of polychemotherapy according to the scheme fluorouracil + cisplatin, laparotomy, extended hysterectomy according to Wertheim type and combined radiation therapy of the small pelvis according to the BOX type. All patients were divided into 2 groups. The first control group consisted of 32 (36.8%) patients with cervical cancer who underwent complex treatment in various sequences, without relapse for three years. The second group included 55 (63.2%) patients with the same diagnosis, but in whom, after complex treatment, an early relapse was detected at the preclinical stage. Results: - In the study of intense infiltrate with lymphoid follicles, it was mainly observed with the degree of tumor differentiation G-3 and G-4, which amounted to 21 (80.7%) patients in the relapse group, while in the control group in 19 (61%) which significantly higher (p≤0.05). In group 1, negative expression was noted in highly and moderately differentiated tumors 9 (29%). With low and undifferentiated tumors, moderate and high expression of VEGF (50%) was noted, with further observation in these patients, locoregional recurrence was noted. In the second group, where there was a relapse of the cervical stump by histological examination, high expression with G-4 was noted in 8 (30.7%), and with G-3 moderate expression in 6 (23%) cases. Low intensity was observed only in 1 (3.8%) G1.As can be seen in Table 4.2, negative expression during relapse, i.e. the absence of lymphoid Conclusions: - Based on our research, differences in cellular immunity play a significant role. In patients without relapses, an increased cellular density of T3DM and T20 was observed, and in patients with relapses and severe course of the disease, low lymphoid density. We should note that in our study, the strongest predictor of prognosis is the number of CD3 + cells per mm 2.

Inscriptions in Hebrew on Ceramic Ware of the 17th—18th Centuries

In the article the authors deal with the verification, attribution and introduction into scientific circulation of a number of Hebrew inscriptions on Early Modern ceramic vessels. This issue has not been raised in the Ukrainian archaeological publications yet. Such isolated inscriptions were previously wrongly interpreted as potters’ marks. More than a dozen of vessels with inscriptions in Hebrew are known today. In particular, they were found during the excavations of three cities — Bila Tserkva, Kyiv, Ostroh. These are fragments of three plates, two small and one large mugs, which come from the cellar of the first half of the 17th century in Ostroh, two plates and a mug from the building of the late 17th — early 18th centuries in Bila Tserkva, as well as a pot from the building of the 17th century in Kyiv. Two groups of inscriptions can be distinguished. The first one is Passover inscriptions on vessels that were obviously intended for the Passover Seder (a symbolic set of products for a holiday supper) or for daily usage during the holiday. Using an additional set of vessels to the holiday is explained by kashrut norms and specific prohibitions of kvass use. The mug with an inscription “kimkha de Piskha” (“flour for Pesach”) belongs to the second group. It was associated exclusively with religious needs and was intended for the collection of donations (tzadaka) on Passover. Tzadaka as a religious obligation to perform charity laid at the basis of the Jewish community existence. It led to the proliferation of different types of money boxes for collecting donations. In general, the topic requires detailed investigations with the involvement of additional archaeological materials, interpretation and introduction of hitherto unpublished materials into scientific circulation.

Design and Comparative Analysis of Ladder Frame Truck Chassis

This research paper titled "Design and Analysis of Chassis" aims to investigate the mechanical behavior of three different materials namely Steel alloy302, Steel alloy4130, and AA 7068 on different cross-sectional shapes of a ladder frame chassis - C, I, and Box (Hollow). The design of the chassis is created using Solid Works 2013 software, and static analysis is conducted using Ansys software R18.0. The results obtained from the analysis provide information on the total deformation, equivalent strain, and equivalent stress of each material on different cross-sectional shapes. For the C type cross-section, it is observed that Steel alloy302 and Steel alloy4130 have higher total deformation and equivalent strain compared to AA 7068. However, the equivalent stress is higher for AA 7068. For the I type cross-section, Steel alloy4130 shows the highest total deformation and equivalent strain, while AA 7068 exhibits the highest equivalent stress. Finally, for the Box (Hollow) type cross-section, the total deformation and equivalent strain are highest for Steel alloy4130, and the equivalent stress is highest for Steel alloy302. These results provide valuable insights into the behaviour of different materials on different cross- sectional shapes of a ladder frame chassis. The findings can be utilized to optimize the design of the chassis for better performance and durability. The study emphasizes the importance of material selection and cross-sectional shape in the design of a chassis for various applications. Key Words: Chassis, SOLIDWORKS Modelling, Static Analysis

Comparing two types of mainstream disposable lunch boxes by LCA and exploring the possibility of converting carbon dioxide into products

BackgroundA disposable lunch box is an important cause of “white pollution”. Many people consider that the disposable polylactic acid (PLA) lunch box is more environmentally friendly than the disposable paper pulp lunch box and can substitute for the latter. ObjectiveWe can determine whether PLA tableware is more environmentally friendly than paper tableware by analyzing the product life cycle of two tableware types. At the same time, as a continuous compound, carbon dioxide has significant commercial value. Carbon dioxide materials' applications range from beverages to cosmetics and building materials. The future application of carbon dioxide in the field of lunch boxes is discussed in this paper. MethodsIn this paper, the production stages of the two types of disposable lunch boxes were compared and surveyed using the life cycle assessment (LCA) method. ConclusionThe results reveal that the main impact of the two types of lunch boxes is resource damage; the PLA lunch box is not better than the paper type; the production stage of the disposable PLA lunch box poses greater damage to the environment in all aspects than the paper type. DiscussionAgainst the background of carbon neutrality and based on the constantly mature carbon dioxide conversion technology, the author explored the possibility of making products from carbon dioxide and proposed to make product designs based on carbon dioxide.

Construction of the genetic switches in response to mannitol based on artificial MtlR box

Synthetic biology has rapidly advanced from the setup of native genetic devices to the design of artificial elements able to provide organisms with highly controllable functions. In particular, genetic switches are crucial for deploying new layers of regulation into the engineered organisms. While the assembly and mutagenesis of native elements have been extensively studied, limited progress has been made in rational design of genetic switches due to a lack of understanding of the molecular mechanism by which a specific transcription factor interacts with its target gene. Here, a reliable workflow is presented for designing two categories of genetic elements, one is the switch element-MtlR box and the other is the transcriptional regulatory element- catabolite control protein A (CcpA) box. The MtlR box was designed for ON/OFF-state selection and is controlled by mannitol. The rational design of MtlR box-based molecular structures can flexibly tuned the selection of both ON and OFF states with different output switchability in response to varied kind effectors. Different types of CcpA boxes made the switches with more markedly inducer sensitivities. Ultimately, the OFF-state value was reduced by 90.69%, and the maximum change range in the presence of two boxes was 15.31-fold. This study presents a specific design of the switch, in a plug-and-play manner, which has great potential for controlling the flow of the metabolic pathway in synthetic biology.Graphical

The effect of management practices on eggshell cleanliness, bacteria levels, and cuticle deposition in pastured poultry

Small-scale egg production is a growing industry in New England. However, foodborne illness risk exists from small-scale pastured eggs due to lack of guidelines for safe handling and management practices. A survey was distributed to backyard poultry owners and producers in the Northeast and indicated a variety of management practices were used. Based on these results, we developed a set of experiments to determine if these management practices influenced eggshell bacteria levels and cuticle deposition. We hypothesized that the manure level (ML) of the eggs and management practices will affect both the total bacterial levels (measured in relative light units = RLU) and the cuticle deposition (CD) of the eggshell. The management practices tested were nest box type (rollaway and conventional style), nest box location (mounted vs floor level access), nesting substrate (straw, shavings and ​​AstroTurf® Nest Pads), and time/frequency of egg collection. The CD experiments involved nest box type and nest substrate management practices only. In conclusion, management practices that minimize manure levels on eggs, like time of egg collection as found in this study, can help to maintain lower eggshell bacteria levels to reduce food safety risk.

ADVANCES IN SOLAR COOKING IN DEVELOPING COUNTRIES - A REVIEW

Increased energy demand has forced societies to rely on traditional fuel sources with negative health andenvironmental impacts. In most developing countries, solar energy is available for long hours and in ranges thatif exploited can reduce dependence on biomass and fossil fuels. However, despite its potential, uptake of solarcooking devices is low due to intermittent radiation, technological challenges, lack of awareness and slowercooking rates compared to other energy sources. There are four traditional types of solar cookers, box, panel,parabolic and tube. The latest technology is the PV conversion to electricity. Since the advent of solar cooking,numerous experiments, designs and improvements of solar cookers have been successfully developed. Researchhas focused on improving solar cooker performance such as; improved design, sun tracking mechanisms, solarthermal storage or “hybrid” designs that remove limitation of nighttime cooking or periods of poor irradiance.These improvements have increased the efficiency, reduce the cost of the solar cookers, and addressedsociocultural challenges such as sheltered cooking, visual appearance, and the ability to cook traditionalrecipes. However, more needs to be done to increase ease of adoption, the capacity of energy storage andflexibility. The cost of domestic workloads and environmental degradation should also be a factor in energypolicy formulation.

Experimental investigation on the lateral performance of CLT shear walls connected to perpendicular walls

Typically, the mechanical behavior of CLT shear walls for lateral loads is assumed to be governed by the wall base connections, such as hold-downs and angle brackets. However, many experimental and numerical studies available in literature have shown that in “box type” CLT buildings, the connections between perpendicular walls contribute to the lateral response of the CLT shear walls. This study presents the results of an experimental campaign aimed at investigating the lateral performance of CLT shear walls connected to perpendicular walls. Two CLT wall assembly configurations were tested: single Shear Wall configuration (SW), which considers a single CLT shear wall subjected to lateral load, and Shear Wall connected to Perpendicular Wall configuration (SW+PW), which considers a CLT Shear Wall connected to a Perpendicular Wall subjected to lateral load. Results showed that the SW+PW configuration reached higher structural performance in terms of lateral stiffness and lateral capacity than single SW configuration. This increase of lateral performances is governed by the properties of the wall-to-wall connections as well as the properties of the hold downs used in the perpendicular walls. Results of this experimental study show that the perpendicular walls and wall-to-wall connections may be included in the design models of CLT shear walls subjected to lateral loads.

Social, environmental and economic assessment of box-type solar cookers for domestic acceptance in India

To protect the environment, the United Nations Climate Change Conference was held in Glasgow with an agenda to maintain the global average temperature well below 2 °C at the preindustrial level, the substitutability of coal power plants, and inefficient conventional power plants. These goals can also be supported at the domestic level by the replacement of conventional cooking processes with box-type solar cookers. Several clean fuel technologies were adopted by different countries to mitigate the emission as mentioned in the literature but the adoption of solar cooking is lagging. This article examines various aspects of a box-type solar cooker that can increase community adaptability, such as cooking time assessment, social, environmental, and economic factors. In the present study, solar radiation data is collected and cooking time assessment for 4 members of the family is evaluated for the requirement of 1.5 kg rice and 0.5 kg of alloe matter sabzi. The requirement of heat is 1.4 MJ for cooking the food and this energy can be available by 2 pm when food is placed at 11: 00 am inside the cooking pot of box type solar cooker. Further, this article covers several social parameters which influence the adaptability of box-type solar cooker. In environmental analysis, the use of solar cooker indicates a reduction of 16.32 kg of CO2 monthly when used for single meal cooking in a day. The economic parameters discussion helps in the replaceability of materials used in the solar cooker to minimize the cost.

Experimental thermal performance studies on solar hot box cooker with different absorber coating materials

Hot box-type solar cookers can be a promising option for meeting the challenges of clean cooking fuel for communities in developing countries. One of the major components of hot box solar cookers is the absorber tray, which is responsible for converting solar radiation into useful thermal energy for a heating load. For improving the efficiency of the hot box solar cooker it is important to enhance the absorption. The present work focuses on enhancing the thermal performance of solar cookers using different absorber coating materials on the absorber tray. Comparative studies on box-type solar cookers have been done for black matt paint and mixed material paints. Five types of mixed material paints were prepared by mixing CuO, TiO2, activated carbon, Tungsten, and mica with black paint. These prepared mixed material paints were examined in reference to the black matt paint on the identical sections of box type solar cooker. The experiments were conducted with different coating materials with water load and without load conditions. During the experiments, the surface temperature difference without load was found to be in the range of1°C to 14 °C for different materials. With water load conditions, the hot water temperature difference was observed to be about 1 °C to 7 °C for different coatings.

PERFORMANCE AND ANALYSIS OF BOX TYPE SOLAR COOKER USING ANSYS

In view of the words depleting a fossile fuel reserve, which provides the major source of energy, the development of non-conventional renewable energy source has received an impetus. Solar energy is most important among renewable energy sources due to its quantitative abundance.

The most important and basic components of the system required of a solar energy into thermal energy is called solar cooker. A solar cooker is a device designed to absorb the incoming solar radiant energy converting into thermal energy at the absorbing surface and transferring this energy through the vessel of the solar cooker. To designed, and conduct experiments on single reflector box type solar cooker with two different Heat absorber systems and to analyze theoretically the performance of this system for different operating conditions and to optimize the system parameters

Topology Optimization of Stiffener Layout Design for Box Type Load-Bearing Component under Thermo-Mechanical Coupling

The structure optimization design under thermo-mechanical coupling is a difficult problem in the topology optimization field. An adaptive growth algorithm has become a more effective approach for structural topology optimization. This paper proposed a topology optimization method by an adaptive growth algorithm for the stiffener layout design of box type load-bearing components under thermo-mechanical coupling. Based on the stiffness diffusion theory, both the load stiffness matrix and the heat conduction stiffness matrix of the stiffener are spread at the same time to make sure the stiffener grows freely and obtain an optimal stiffener layout design. Meanwhile, the objectives of optimization are the minimization of strain energy and thermal compliance of the whole structure, and thermo-mechanical coupling is considered. Numerical studies for square shells clearly show the effectiveness of the proposed method for stiffener layout optimization under thermo-mechanical coupling. Finally, the method is applied to optimize the stiffener layout of box type load-bearing component of the machining center. The optimization results show that both the structural deformation and temperature of the load-bearing component with the growth stiffener layout, which are optimized by the adaptive growth algorithm, are less than the stiffener layout of shape ‘#’ stiffener layout. It provides a new solution approach for stiffener layout optimization design of box type load-bearing components under thermo-mechanical coupling.

SOLAR STOVES AS AN ALTERNATIVE SOLUTION FOR THE USE OF RENEWABLE ENERGY IN INDONESIA

Along with the development of technology, the need for fossil energy for cooking purposes using conventional stoves is increasing. The limitations of fossil energy reserves that cannot be renewed have resulted in an energy crisis starting to hit. Solar energy is an energy source that is environmentally friendly and available free of charge. Solar energy is utilized using the system. Concentrating solar power (CSP) focuses solar radiation to a point to get a higher temperature. This type of box-type solar cooker has a long history dating back to the 18th century when Nicholas-de-Saussure first made this type of solar cooker. A parabolic solar cooker is a solar-powered stove that uses reflections from the sun's radiation which is concentrated directly on the pan. A trough solar cooker collects sunlight and reflects it to a focal point using a reflective film. A box-type solar cooker has an important part between the reflectors which use aluminum foil with a diameter of 41 cm and a thickness of 0.2 mm. The collector was made of brass copper for cooking with a diameter of 41 cm and a thickness of 0.2 mm. The parabolic type of solar cooker has important parts, including a collector that uses a parabola with a diameter of 140 cm and a depth of 40 cm and a reflector that uses a reflective film with an emissivity value of 0.91. The trough-type solar cooker performs better than the box and parabola types because it has a higher temperature where the ambient temperature is 25.5 ℃, the focal point temperature is 164℃, and the load temperature is 163℃.
