Resumen

Quality characteristics of 30 commercial wheat flour samples from Czech industrial mills and 30 wheat flour samples prepared from wheat varieties cultivated in experimental fields (all from wheat harvest 2000) were analysed in detail including maturograph and spring oven (both from Brabender, Germany) as well as bread baking test (Czech method). Specific bread volumes of all flour samples were compared with the bread volumes determined by the oven spring test. The correlation analysis which expressed the relations between wheat flour rheological characteristics and the bread volume is reported. The maturograph parameters correlate significantly with the specific bread volume and the final volume obtained by means of oven spring. All the correlations with the baking test values are high. Both instruments used are suitable for the prediction of the flour baking quality.

Resumen

This paper describes the thermal performance of a novel solar oven that incorporates a compact reflec-tive lens, or ring array, to augment sunlight concen-tration. Performance is reported in terms of the pos-itive effect of the ring array versus a non-concen-trating lid, maximum operating temperature, ther-mal efficiency, performance under partly cloudy skies, and the effects of incidence angle and track-ing. Use of the ring array lens improved thermal efficiency by 4% in the test range up to 100°C, while boosting the maximum operating temperature from 138°C to 196°C. Comparative tests conducted under clear sky conditions against two other com-mercial types showed that when tracked in the azimuth plane at near-normal incidence angles, the new design generated maximum cooking power of 300 W and boiled water at a rate 13% faster than the next best commercial oven tested. Augmented sunlight concentration sensitised the new design to higher angles of incidence and performance was negatively affected in the non-tracked state. Under non-ideal operating conditions, including partial shading by cloud, the oven outperformed both commercial units.

Resumen

SummaryHeat stability of secreted bacterial proteinase is normally assessed using an oil bath test in which the sample is heated at a temperature and time representing the commercial UHT treatment of milk. The temperature/time (T/t) profiles of the oil bath and the commercial UHT process being represented are not taken into account. Two laboratory procedures were used to simulate a commercial UHT process in which milk was heated to 140°C and held for 3 s in a Spiroflo heat exchanger. They consisted of a conventional oil bath test and the use of a programmable, electronically temperature-controlled oven.T/tprofiles were established for each heat treatment. TheT/tprofile of the oil bath test was predicted accurately using the governing heat transfer equation.B*andC*values, which measure the severity of a heat process, were calculated from theT/tprofiles and used to compare the three different heat treatments.B*andC*values of 4·95 and 1·92 respectively were calculated for the Spiroflo heat exchanger. An oil bath test, in which the sample was immersed in a bath at 136°C for 73 s, gave approximately the sameB*andC*values as calculated for the Spiroflo heat exchanger.B*andC*values of 5·01 and 1·73 respectively were calculated for the oven procedure. The oven test gave the better laboratory simulation of the Spiroflo UHT treatment. Despite the slight difference in each of theB*andC*values between the oven and the Spiroflo, theT/tprofile of the oven test closely resembled that of the Spiroflo. TheT/tprofile of the oil bath was completely dissimilar. Although it was possible to use an oil bath test to replicate simultaneously both theB*andC*values of this particular UHT treatment, this would not be the case for other commercial processes.

Resumen

Microwave oven was utilized to fabricate carbon nanostructure, specifically CNTs, from waste RH powders. It has been shown that the use of carbon source, catalyst, and commercial microwave oven to induce plasma is necessary to carry on this synthesis. The plasma enhances and speeds up the catalytic decomposition of RH in presence of ferrocene. FESEM, TGA, and Raman spectroscopy were utilized to confirm the presence and quality of produced carbon nanomaterials. In addition, these results suggest the conversion of ferrocene to iron(II, III) oxide with notable conversion rate.

Resumen

A plane is a tool related to woodworking, which is used for smoothening the surface of the wood. Currently, there are many different smoothing planes available in the market. In this study, the evaluation of a self-made hand plane was conducted. One of the variables that can be utilized to investigate smoothing plane’s performance is by analyzing its wood’s surface smoothening capability. In this reserch, the smoothening capability was evaluated by measuring the wood’s surface roughness after the smoothening process. This study was conducted by utilizing three different types of wood namely limestone wood, meranti wood, and kempas wood as well as three different planes that are a mini plane (self-made tool), a commercial plane, and a power planer. The results show that prior to smoothening process, the maximum surface roughness was 16.432 µm for wet limestone wood and the minimum was 7,871 µm for kempas oven wood. After the smoothening process, the surface maximum roughness values are 10,932 µm using hand mini plane, 12,329 µm for kapur basah wood with the commercial plane for kapur basah wood and minimum roughness of 4,982 µm obtained hand mini plane for meranti oven wood and 5,826 µm for meranti oven wood with the commercial plane. It was also observed that the self-made mini plane gave lower values of surface roughness compared to commercial plane. Thus, it could be summarized that the self-made plane (mini hand plane) is capable to be used for the wood surface smoothening and it has better performance compared to the commercial plane.

Resumen

Decalcification of hard tissues such as bone and teeth is a complex process that requires using chemicals such as acids and chelating agents. Acids act faster than chelating agents, but they have a greater risk of damaging biological samples. Increasing the reaction speed of the chelating agent may solve this issue. There are several strategies to speed up this process, and using microwaves seems to be one of the most effective. However, lab-dedicated microwave ovens are expensive, and their purchase may seem unjustified. Therefore, a low-cost modification of a commercial microwave oven, consisting of an Arduino automation device, has been developed. The setup has proven reliable for continuous work, thanks to implementing an electronic safety circuit. In addition, it may reduce the decalcification time using a chelating agent, achieving optimal results regarding tissue preservation and quality of histological sections.

Resumen

A walk-in type semi-cylindrical-shaped solar tunnel dryer (10 m x 3.75 m) was designed, developed, and evaluated at Dr. B.S. Konakan Krishi Vidyapeeth, Dapoli for thermal analysis. The dryer was evaluated by conducting the no-load test at the laboratory to study the thermal profile, energy input/output during the winter and summer seasons. Based on the laboratory experience, a commercial-scale solar tunnel dryer was installed and evaluated at M/s Shirodkar Food Products Pvt. Ltd., kudal, District Sindhudurg (MS) for commercial mango leather drying. The dryer was loaded with 250 kg mango pulp per batch by spreading over 210 number of grease-proof aluminum trays (1.2 kg pulp in each tray) in three layers (70 trays in each layer). Drying of mango leather was studied in comparison with open sun drying and electrical oven drying for time saving and energy consumption. The study revealed that the average rise in temperature of drying air was about 18 -22 0C over the ambient air. The average drying period reduced by 28 % over open sun drying method. The average temperature inside the solar dryer was 62+5 0C, and required 10 h for upper layer of trays, 13 h for second layer of trays, and 17 h for the third level of trays as compared to 26 h in open sun drying. The operating energy cost of solar tunnel dryer was zero as compared to 102 kWh in an electrical oven. Considering drying of 30 batches per season, the payback period of the system was 2.7 years

Resumen

The performance of microelectromechanical system (MEMS) inertial measurement units (IMUs) is susceptible to many environmental factors. Among different factors, temperature is one of the most challenging issues. This report reveals the bias stability analysis of an ovenized MEMS gyroscope. A micro-heater and a control system exploiting PID/PWM were used to compensate for the bias stability variations of a commercial MEMS IMU from BOSCH “BMI 088”. A micro-heater made of gold (Au) thin film is integrated with the commercial MEMS IMU chip. A custom-designed micro-machined glass platform thermally isolates the MEMS IMU from the ambient environment and is vacuum sealed in the leadless chip carrier (LCC) package. The BMI 088 built-in temperature sensor is used for temperature sensing of the device and the locally integrated heater. The experimental results reveal that the bias repeatability of the devices has been improved significantly to achieve the target specifications, making the commercial devices suitable for navigation. Furthermore, the effect of vacuum-packaged and non-vacuum-packaged devices was compared. It was found that the bias repeatability of vacuum-packaged devices was improved by more than 60%.

Resumen

Abstract Objectives The project tested the hypothesis that baked sweet potato chips will retain nutrients and can be produced with lower fat than commercially prepared fried chips. Sweet potato is a staple food that is a good source of dietary fiber, copper, manganese, antioxidants, vitamins C, A, B6, and E and is low in calories and fat. Orange-fleshed sweet potato is a good source of beta-carotene, a vitamin A precursor. Due to its nutritional benefits, demand is increasing and a growing market has created a variety of sweet potato products. Beta-carotene is a heat, light, oxygen labile molecule that can be used as a marker for nutrient degradation when sweet potato is heat-processed. Most commercial sweet potato chips are fried in oil, which helps to lower the glycemic index, but may also lower the nutrient density in the higher calorie product. Our goal is to test newer methods for making baked sweet potato chips with commercially available air-fryers and compare the products to chips baked with conventional and convection ovens. Methods Sweet potato chips were prepared from fresh commercially purchased Covington sweet potatoes cut into 3 mm slices with a semi-automatic food slicer. The slices were lightly sprayed with a vegetable oil aerosol and cooked in air fryers for 15 min at 400°F (204°C), in convection ovens for 15 minutes at 415°F (213°C), and in conventional oven at 400°F for 20 minutes. Crispness was determined by a 3-point bending test. Results The fresh sweet potato contained 22% DM and the chips averaged 70% DM after cooking in air fryers, 60% DM after cooking in convection ovens, and 64% DM after cooking in conventional oven. Beta-carotene content was 24.2 ± 4.5 mg/100 g DM in the fresh sweet potato, and decreased to an average 7.6 ± 1.9 mg/100 g DM in the air-fried chips, 14.1 ± 4.1 mg/100 g DM in the chips cooked in the convection ovens, and 6 ± 1.7 mg/100 g DM in the conventional oven. The rheological test found the chips with greater beta-carotene retention from the convection oven to be less crisp and have less charring than chips made in the air fryer or in the conventional oven. Conclusions Air frying technology shows promise for making low-fat sweet potato chips but nutrient degradation may still be an issue that needs further research.

Resumen

The microwave oven is a valuable tool for light and electron microscopy microtechnique labs. Tissue processing times, traditionally taking up to two weeks, have been reduced to a few hours as a result of the implementation of microwave technology (Kok et al., 1988, Gibberson and Demaree, 2001). In addition, the quality of the tissue preparations has improved dramatically. Microwave ovens have also evolved since their first use in the laboratory. Early experiments were conducted using relatively crude commercial microwave ovens. Now, labs use microwave ovens with temperature probes, strict control over the magnetron (which generates the microwaves), variable power supplies, chamber cooling, and high microwave field uniformity.

Resumen

Commercial microwave oven 800 W for sintering hydroxyapatite is being developed. The required temperature for sintering hydroxyapatite is 1200°C. A temperature 1200°C can be achieved if commercial microwave combined with susceptor and insulators material. This research is aiming to study about the effect configuration of SiC and Ceramic Fiberboard thickness to temperature rise. The results show that the presence of SiC with a thickness of the thinnest affect significantly temperature rise. The presence of CFb, as a second insulator, decrease the temperature rise and more the CFb thickness increases, more the temperature decreases.

Resumen

We evaluated the effect of commercial times and temperatures for searing, cooking, and holding on the destruction of Escherichia coli O157:H7 (ECOH) within mechanically tenderized prime rib. Boneless beef ribeye was inoculated on the fat side with ca. 5.7 log CFU/g of a five-strain cocktail of ECOH and then passed once through a mechanical tenderizer with the fat side facing upward. The inoculated and tenderized prime rib was seared by broiling at 260°C for 15 min in a conventional oven and then cooked in a commercial convection oven at 121.1°C to internal temperatures of 37.8, 48.9, 60.0, and 71.1°C before being placed in a commercial holding oven maintained at 60.0°C for up to 8 h. After searing, ECOH levels decreased by ca. 1.0 log CFU/g. Following cooking to internal temperatures of 37.8 to 71.1°C, pathogen levels decreased by an additional ca. 2.7 to 4.0 log CFU/g. After cooking to 37.8, 48.9, or 60.0°C and then warm holding at 60.0°C for 2 h, pathogen levels increased by ca. 0.2 to 0.7 log CFU/g. However, for prime rib cooked to 37.8°C, pathogen levels remained relatively unchanged over the next 6 h of warm holding, whereas for those cooked to 48.9 or 60.0°C pathogen levels decreased by ca. 0.3 to 0.7 log CFU/g over the next 6 h of warm holding. In contrast, after cooking prime rib to 71.1°C and holding for up to 8 h at 60.0°C, ECOH levels decreased by an additional ca. 0.5 log CFU/g. Our results demonstrated that to achieve a 5.0-log reduction of ECOH in blade tenderized prime rib, it would be necessary to sear at 260°C for 15 min, cook prime rib to internal temperatures of 48.9, 60.0, or 71.1°C, and then hold at 60.0°C for at least 8 h.

Resumen

Despite widespread popularity, today's microwave ovens are limited in their cooking capabilities, given that they heat food blindly, resulting in a nonuniform and unpredictable heating distribution. We present software-defined cooking (SDC), a low-cost closed-loop microwave oven system that aims to heat food in a software-defined thermal trajectory. SDC achieves this through a novel high-resolution heat sensing and actuation system that uses microwave-safe components to augment existing microwaves. SDC first senses the thermal gradient by using arrays of neon lamps that are charged by the electromagnetic (EM) field a microwave produces. SDC then modifies the EM-field strength to desired levels by accurately moving food on a programmable turntable toward sensed hot and cold spots. To create a more skewed arbitrary thermal pattern, SDC further introduces two types of programmable accessories: A microwave shield and a susceptor. We design and implement one experimental test bed by modifying a commercial off-the-shelf microwave oven. Our evaluation shows that SDC can programmatically create temperature deltas at a resolution of 21°C with a spatial resolution of 3 cm without the programmable accessories, and 183°C with them. We further demonstrate how an SDC-enabled microwave can be enlisted to perform unexpected cooking tasks: Cooking meat and fat in bacon discriminatively and heating milk uniformly.

Resumen

Sacha inchi (Plukenetia volubilis L.) has been adopted as a novel economic crop with well-studied nutritional and bioactive benefits for human health. Sacha inchi seeds and oil have high commercial value but scant research has focused on its leaves. This study investigated and compared phenolic compositions, antioxidant potentials and in vitro health-related properties of both young and mature sacha inchi leaves after freeze-drying and oven-drying processes. Results showed that p-coumaric acid, 4-hydroxybenzoic acid, ferulic acid and gallic acid were predominantly detected in both young and mature leaves that also exhibited similar total phenolic contents (TPCs), while higher TPCs were detected in freeze-dried than in oven-dried leaves. Mature leaves exhibited higher antioxidant potential than young leaves after freeze-drying, while the opposite results were observed for oven-drying. Overall in vitro health-related activities were higher in mature leaves compared to young leaves regardless of the drying process. Knowledge gained from this study can be used to encourage prospective utilization of sacha inchi leaves as a source of health-promoting compounds. This, in turn, will increase the commercial value of the leaves and provide a wider market variety of sacha inchi products.

Resumen

A commercial phenol formaldehyde based resole thermosetting resin supplied by Borden Chemical Australia Pty. was filled with ceramic-based fillers (Envirospheres or SLG) to increase its flexural strength. By performing flexural tests at a range of filler addition levels, the optimal addition level of SLG was able to be determined in terms of workability, cost and performance. The composites obtained were post-cured in conventional oven and in microwaves respectively. It was found that the maximum flexural strength of the microwave cured composites were only 5% lower than those cured in conventional oven when the percentage by weight of SLG was 24%. However, the time required for post-curing was also reduced from 10 hours (in conventional oven) to 40 minutes (in microwaves).

Resumen

Drying is generally used to increase the shelf life of food products. In this context, mango fruit is used as a sample for the drying process because of its high commercial value and particularly high moisture content. The mango was sliced into few batches of sample with a size of 20 mm × 30 mm × 5 mm each. The experiments were conducted using tray and oven dryer at different temperatures of 40, 50 and 60 °C with a steady airflow rate of 1.3 m/s. The objectives are to study the effect of drying time, temperature and air velocity towards drying of mango fruit, to compare the physical characteristics of mango sample after drying and to determine the best drying kinetics model fitted to each tray and oven dryer. The results showed that the increase in drying time, temperature and air velocity would reduce the moisture content while at the same time, drying rate increased significantly. Tray dryer was found to be more effective than oven dryer because of higher drying rate with better product quality and appearance at the end. Furthermore, the gathered data were fitted into few widely used drying mathematical models and it was found that Henderson and Pabis model at 60°C is best suited for tray dryer whereas Page model at 40 °C is the best for oven dryer.

Resumen

Some bacteria emits light in the dark. The aim of this research is to find lighting duration and medium composition which produce the most enduring luminescence. The results showed that one of the bacteria isolated from light organ of Loligo duvacelli (D'Orbigny, 1835) squid are able to emit light. The isolation use trisalt solution and cultured into nutrient agar with addition of NaCl emits the longest blue-green light duration under a 1:1 dark-light shift incubation 8.3 d. Meanwhile under a total light, total dark, and in the oven incubator it illuminate for 4.2 d, 3.6 d and 2.6 d, respectively. The combination of beef extract + peptone + a commercial agar + NaCl generate the longest duration of luminescence when incubate in the oven incubator (3,2 d). Meanwhile it illuminated for 2.6 d and 1.7 d on NA + NaCl and NC + NaCl media, respectively, but it failed to illuminate on PCA, NA, and green beans extract + commercial agar + NaCl media. Based on this research we conclude that a commercial agar is potential to replace a technical bacterial agar function. <div>Keywords: bioluminescence; commercial agar; light treatments; Loligo duvaceli (D'Orbigny, 1835); medium treatment.</div>

Resumen

The Roll-to-Roll (R2R) process refers to a high-efficiency, low-cost, continuous production method. The roll material used for processing is a flexible plastic or metal film. In many R2R processes, polarizing films are high-precision products with a high output value. In the production of conventional polarizers, product inspection will only be carried out after the production of the polarizing film is completed. The principal raw material of a polarizer sheet is a hydrophilic polymer, the properties of which may be influenced by water vapor, which degrades its quality. Whether or not the product is impacted can be ascertained by means of a quality inspection, but it must be performed after the process is finished. However, it is already too late when a defective product is detected: the production cost is increased, the schedule is influenced and the delivery date is delayed. The focus of this research was on environmental monitoring of the production drying process oven, but the commercial all-in-one sensors currently on the market cannot tolerate the temperature of the factory’s high-temperature oven. In particular, a commercial flow sensor is rarely suited to high-temperature applications. Some are expensive and cannot be widely distributed. Therefore, this study aimed to develop an integrated sensor to measure the internal environment of the drying process oven for the real-time monitoring of a polarizer sheet in the Roll-to-Roll (R2R) process. This study used micro-electro-mechanical systems (MEMS) technology to make a flexible three-in-one (temperature, humidity and flow) micro-sensor. We monitored the temperature, humidity and flow uniformity in a laboratory oven to simulate the environment of the actual factory oven, with the aim to provide data to confirm whether or not a polarizer sheet has dried. Our system can be monitored instantly by Arduino, or even Raspberry Pi 3, to realize the flexible micro-sensor layout and field verification, in order to optimize the R2R process and to enhance the yield and performance of the polarizer sheet process.

Resumen

Asphalt aging has a direct influence on the durability of asphalt mixture. In order to improve thermal oxidizing aging resistance of asphalt, the commercial antioxidants including Irganox 1010 and Irgafos 168 were selected to modify base asphalt and SBR asphalt. The basic properties of modified asphalt before and after the rolling thin film oven test (RTFOT) are evaluated by penetration, softening point, ductility, and viscosity. The Fourier transform infrared spectroscopy (FTIR) test was applied to determine the antiaging mechanism of modified and unmodified asphalt. According to the test result, Irganox 1010 not only reduces the aging degree of asphalt but also has little adverse effect on other properties. Irgafos 168 with a content of 1% improves the low temperature ductility of asphalt and improves the antiaging performance of asphalt significantly. After RTFOT, the content of oxygen-containing functional groups (carbonyl group and sulfoxide group) declines significantly in antioxidation modified asphalt, and Irganox 1010 and Irgafos 168 inhibit oxidizing reaction in the aging procedure. This study can provide a useful reference for improving the aging property of asphalt in highway construction.

Resumen

Chemical fixation of large biological tissues in electron microscopy has a disadvantage that fixative doesn’t penetrate well into the deeper part of the tissue. My experience suggests that the poor penetration by chemical fixation can be improved by microwave fixation. Temperature raise caused by microwave irradiation is regulated by the cold bath on the floor of the oven. This paper shows that microwave fixation is readily practicable together with conventional fixation. Well-fixed section with an area as large as 1×5mm is observable and the details of morphological structures are preserved quite well in it.A commercial microwave oven (National Microwave Oven Model NEM-335,2.45GHz 500/180W) was used for the microwave fixation. Irradiation period was controlled by Omuron H5cN-AN. Young mouse kidney and brain were used. The tissue in a glass vial placed in the cold bath was immersed in the mixture of 2% paraformaldehyde and 0.5% glutaraldehyde in phosphate buffer (pH7.4),followed by microwave irradiation for 10 sec. twice.

Resumen

Blood serum separator tubes (SST) are used for collecting blood samples for performing clinical chemistry assays. Some SST's have separator gels inside the tube which enable them better separation of the blood serum from packed cells during centrifugation. The cost, weak performance and interaction with blood ingredients are the most concerns of the available commercial gels. A commercial and cheap silicone oil as a polymeric base of the gel was chosen and formulated without and with several fillers. Subsequently, the compounds were crosslinked through a free radical crosslinking mechanism using dicumyl peroxide (DCP). The crosslinking took place in both, an oven and as well as under microwave irradiation in normal and under pressure conditions. The FTIR spectrometer analysis showed that both chain ends of the used silicone oil were terminated with a vinyl group. It also revealed that blood serum separator gel can be produced from selected silicone oil type. Among of different curing apparatus, curing in an oven was preferred due to less curing time and electrical energy consumption. The curing in normal pressure showed better results when compared with curing under pressure. Increasing the filler and DCP with various amounts had positive effect on gel densities. Silica was the most efficient filler among of the studied fillers. The cured compound filled with 10 and 8 phr silica and DCP, respectively, was chosen as appropriate gel for SST due to suitable density and thixotropy. The selected gel was cured in oven under normal pressure for 30 minutes at 160°C.

Resumen

A test that takes less than one hour as opposed to the conventional one day test is proposed for measuring the relaxation shrinkage and hygral expansion of fabrics. There is no need for a controlled environment, the only equipment required being a household microwave oven and a scaled ruler. The test's simplicity makes it suitable for use in a commercial environment, especially for quality control during fabric finishing and garment making.

Resumen

In the search for another appealing source of future food to cover the increasing need for nutrients of a growing global population, this study reviewed the potential of insects as human food. Most previous reviews have dealt with insects as a group, making it difficult to evaluate each individual insect species as food because of the generalized data. This study assessed some common edible insects, but concentrated on mealworms. Insects, especially mealworms, have a similar or higher nutritional value than many conventional food sources. For example, the protein content of mealworm larvae is reported to be almost 50% of dry weight, while the fat content is about 30% of larval dry weight. Mealworms can be cooked by different methods, such as hot air drying, oven broiling, roasting, pan frying, deep frying, boiling, steaming, and microwaving. Oven broiling in particular gives a desirable aroma of steamed corn for consumers. Changes in the flavor, taste, and texture of mealworm products during storage have not been studied, but must be determined before mealworms can be used as a commercial food source. Factors controlling the shelf-life of mealworms, such as their packaging and storage, should be identified and considered with respect to the feasibility of using mealworms on a commercial scale.

Resumen

Vacuum drying can dehydrate materials further than dry heat methods, while protecting sensitive materials from thermal degradation. Many industries have shifted to vacuum drying as cost- or time-saving measures. Small-scale vacuum drying, however, has been limited by the high costs of specialty scientific tools. To make vacuum drying more accessible, this study provides design and performance information for a small-scale open source vacuum oven, which can be fabricated from off-the-shelf and 3-D printed components. The oven is tested for drying speed and effectiveness on both waste plastic polyethylene terephthalate (PET) and a consortium of bacteria developed for bioprocessing of terephthalate wastes to assist in distributed recycling of PET for both additive manufacturing as well as potential food. Both materials can be damaged when exposed to high temperatures, making vacuum drying a desirable solution. The results showed that the open source vacuum oven was effective at drying both plastic and biomaterials, drying at a higher rate than a hot-air dryer for small samples or for low volumes of water. The system can be constructed for less than 20% of commercial vacuum dryer costs for several laboratory-scale applications, including dehydration of bio-organisms, drying plastic for distributed recycling and additive manufacturing, and chemical processing.

Resumen

Vimentin is transiently expressed in many cells of neuroectodermal origin in the fetal central nervous system and may be demonstrated by immunohistochemistry in paraffin sections. Traditional methods incubate antibodies with tissue sections at room temperature, but boiling the incubating solution in a microwave oven enhances antigen retrieval and greatly intensifies immunoreactivity This study compares vimentin immunoreactivity using various dilutions of a commercial monoclonal antibody and various incubation conditions including room temperature, overnight at 4°C, and after heating to boiling either in a microwave oven or on a hot plate. Fifteen fetal brains and spinal cords were examined, ranging in age from 8 to 24 wk gestation. Normal brains of four term or near-term neonates and two with hypoxic/ischemic lesions were also studied. Hot plate and microwave heating were equivalent. No differences in immunoreactivity could be attributed to gestational age per se. Boiling for 10 min in a microwave oven at a dilution of 1:200 is recommended for the enhanced demonstration of fetal histological structures such as radial glial fibers, but it is not recommended for studies of maturational gradients of cellular vimentin that differ at each gestational age, as in fetal ependymal cells or during the conversion of radial glia to mature astrocytes. For semiquantitative developmental studies, vimentin incubation at room temperature or overnight in the refrigerator is recommended at a dilution of 1:25 or 1:50 to avoid misinterpretation of apparent excessive staining after thermal intensification. Recommendations of commercial suppliers focus on the identification of neoplastic cells and must be modified to demonstrate subtle developmental changes in fetal tissues.

Resumen

Abstract Florunner peanuts with red, cracked testae commonly associated with tomato spotted wilt virus (TSWV) infected plants were examined for size, oil quality and flavor variation. Samples of visually normal and red testa peanuts (RTP) were collected randomly by electronic color sorting and hand-picking from three locations in Texas. Size distributions in the samples indicated higher percentages of RTP in smaller commercial sizes. Mean seed weight was lower for RTP except in the single largest screen size (9.5 mm). The oleic/linoleic acid ratio in oil from various commercial sizes was slightly but consistently higher in RTP and oven test stability of oil was correspondingly longer. Descriptive flavor analysis of roasted normal peanuts and RTP indicated no relevant flavor differences.

Resumen

The No. 1 continuous coil coating line of Dongbu Steel produces 70,000 tons of commercial quality products annually, and the pre-coated metal (PCM) products are widely used for a home appliances or building materials. The lines are consisted of pre-treatment, painting, curing and tension levelling processes. The typical curing methods are injection of hot air, infrared rays, electron beam, or induction heated oven. Peak metal temperature (PMT) is the vital factor that determines the product quality. The curing oven of No. 1 continuous coil coating line revamped from injection of hot air to infrared rays type and operated from 2007. A PMT setup model was developed for control the strip temperature, and applied in site, and systemized. The operation results showed that the accuracy of the setup model achieved above 96% consistently.

Resumen

Trace elements in five kinds of flour which were made in Japan. America and Canada, have been measured by means of in-air PIXE. Twelve kinds of trace elements were detected, such as Cl, K, Ca, Sc, Cr, Mn, Fe, Co, Ni, Cu, Zn and Br. The concentration of these elements varied depending on the place where they were made. In order to check the target preparation procedure, two types of sample preparation have been used, such as wet ashing by nitric acid in a microwave oven and making a paste by an internal standard solution. Comparisons of the results of both samples ensures that bromine was not lost during micro-wave oven heating. Analytic fitting of PIXE spectra by a personal computer and a commercial apllication software was successfully used.

Resumen

In order to inspect on wall condition inside the coke oven, an inspection device has been developed to protect a camera inside and sustains high temperature long enough so that it can be permanently-installed on the pusher ram beam. The temperature of the coking chamber during operation is about 1200 °C while the maximum tolerable temperature of a camera is less than 40 °C. The device has to function as a good thermal insulator with cooling element for the camera at the pusher head and for signal cables along the beam. In this paper, the necessary conditions of the inspective device were found out by building a three-dimensional numerical model of the device to simulate the temperature distribution inside the device with CFD commercial software.

Resumen

A preliminary study of the degradation of selected commercial packaging materials in compost and aqueous environmentsThe paper presents the results of the degradation of two commercial packaging materials CONS-PET and BioPlaneta in the compost and distilled water at 70°C. The materials containing polylactide (PLA), CONS-PET 13% and BioPlaneta 20%, aliphatic-aromatic copolyester terephthalic acid/adipic acid/1,4-butanediol (BTA) and commercial additives degraded under the industrial composting conditions (composting pile or container) and in distilled water at 70°C in the laboratory holding oven. Distilled water provided the conditions for the hydrolytic (abiotic) degradation of the materials. Weight loss, changes of molecular weight, dispersity monitored via the GPC technique and the macroscopic surface changes of the tested materials were monitored during the experiments. The investigated systems show similar trends of degradation, however on the last day of the incubation the decrease of the molecular weight was higher in water than under the industrial composting conditions. The results indicate that commercial packaging materials can be degraded both while composting ((bio)degradation) and during the incubation in distilled water at 70°C (abiotic hydrolysis).
