Abstract:

With the wide acceptance of modeling a PV cell by a single diode, a series and parallel resistors; many researchers have discussed different mathematical forms and iterative techniques to extract the values of these model elements depending on the key parameters provided by the manufacturer datasheet. This paper avoids iterative techniques and obtains the values of the five parameters of the one diode model by developing closed form expressions. The maximum error produced by this technique is 10% when compared to the exact values of the one diode model circuit built by Spice. The 10% maximum error has occurred during the estimation of the reverse saturation current (Io) of the diode, nevertheless, it should be mentioned that even for this same parameter the model outperforms many iterative dependent works. Furthermore, this paper discusses the effect of temperature on the operation performance of PV cells. In particular, the temperature effect on the open circuit voltage, the short circuit current, the fill factor, the reverse saturation current, and the conversion efficiency was modeled and evaluated for different brand technologies

Abstract:

The application of electroactive polymer devices requires the availability of their properties at various operating conditions. This in turn necessitates a structure-property relationship based on an in-depth understanding of the underlying mechanism responsible for their strain-field response. Cellulose-based Electro-Active Paper (EAPap) has been studied as an attractive Electro Active Polymer (EAP) material for artificial muscles. The feasibility of EAPap material as an actuator/sensor application is greatly dependant on piezoelectric effect. In this paper, converse and di rect piezoelectric ef fect s of Electro-Active Paper materials are studied to characterize piezoelectric effects of EAPap. All experiments were conducted in an environmental chamber that can control temperature and humidity.

Abstract:

The effect of calendering temperature, speed and linear load on the properties of opacity, brightness, smoothness, paper thickness, gloss and ink absorption of art paper were studied by orthogonal experiment. The art paper coating formulations were as follows: GCC-60 100 pph, solid content 64.6% for precoating; GCC-95 40 pph, Kaolin 60 pph, and solid content 61.3% for top coating. Bar coater was involved to coat by hand in the lab and the coating weight was controlled at 20±2g/m2. After calendering in different conditions, the optical properties and printability of paper were analyzed. Regression analysis was used to study which of the calendering conditions was the dominant factor influencing the paper properties. The results showed that linear load was the dominant one, followed by the calendering temperature and calendering speed. After calendering, smoothness and gloss increased, while the brightness and opacity decreased.

Abstract:

This paper mainly studies the effect of temperature cycling on stress relaxation behavior of contacts for electrical connectors. Based on the analysis of the test specifications of electrical connectors, this paper provides a kind of test method on stress relaxation behavior of electrical connector contacts under temperature cycling conditions. The detecting circuit is designed; the test is carried out and finally, according to the test data, it can be concluded that 1) for the same temperature change, the absolute change of strain within the temperatures above zero is bigger than that within the subzero temperatures; 2) the deformation of contacts gradually increases as the number of cycles increases. The length of the degradation process for electrical connectors might be related with the high temperature value, temperature variation or temperature variation rate.

Abstract:

The Compton scattering is one of the loss processes in fusion media. In this paper the Compton cross-section is calculated in three limits of temperature, non-relativistic, relativistic and ultra-relativistic temperatures. By considering the electron distribution function for all the temperature limits, we found the power of Compton scattering in degenerate media. These results show that the Compton scattering power increases with decreasing electron temperature. So, in degenerate conditions, the Compton loss processes decrease in fusion media.

Abstract:

The electrical, thermal, chemical, and mechanical characteristics of a flexible electrode consisting of carbon nanotubes on paper were investigated under various conditions. The main driving motivation was to develop a durable and flexible film for conductive electrode applications. The general characteristics of the electrode based on carbon nanotubes were found to be sensitive to coating sequence and aging temperature and duration. The number of coatings can be used to tune network density and form a well entangled carbon nanotube layer on paper. Aging temperature was found to be critical to electrical characteristics, and 60 °C was determined to be the optimal aging temperature. At higher temperatures, calcium oxide contained in the paper may form carbonates, which change the structure of the paper, and the carbon nanotubes can be oxidized, which led to reduced electrical performance. The mechanical durability tests revealed that the electrode was functional up to a 3 mm bending radius.

In this paper there have been presented the results of low-cycle fatigue tests of steel P91 samples in the conditions of isothermal fixed amplitude loads as well as loads with a temperature change. Fixed amplitude isothermal loads were conducted on five levels of full strain and in two temperatures T1=20°C and T2=600°C. In the paper there has been found a significant influence of the sequence of temperature changes on the cyclic properties after the temperature change and on the fatigue life. The conducted experimental verification of the Palmgren-Miner hypothesis proved its influence on the temperature changes during the tests.

Abstract:

Woody and agricultural wastes are important fuels in many countries, and have the potential of being even more important in the future. The main problems of plant biomass combustion are low ash melting temperatures and increased emissions. The most widely used treatment to solve the problem of low ash melting point is blending a fuel with an additive. In this work, pellets were produced from wheat straw containing wood sawdust and paper sludge in the following proportions 40:40:20 and 45:45:10 (straw/sawdust/paper sludge). The purpose of this work was to study the influence of sludge and dendromass on the straw pellet parameters and combustion process. The highest calorific value of 15.71 MJ kg−1 was registered for a sample with a 10% paper sludge concentration. The effectiveness of paper sludge was proved, and the ash melting temperature was increased from 1025 to 1328 °C for the same sample.

Abstract:

AbstractHigh cutting temperatures are easily generated during the machining of carbon fibre reinforced plastics (CFRP) and can induce serious damage during machining such as delamination. The purpose of this paper is to study the influence of cutting temperature on the performance of CFRP after machining. CFRP specimens were heated to temperatures within the vicinity of cutting temperatures generated during machining, then air-cooled and their bending properties investigated. The results showed that temperature had significant influence on the bending stress of CFRP. With increasing temperature, bending stress decreased and was lowest when the temperature was close to the glass-transition temperature. It was concluded that the bending properties of CFRP could be seriously affected if the material temperature was close to the glass-transition temperature and maintained for a period. As a result, cutting temperature should be kept lower than the glass transition temperature during machining.

Full text

Abstract:

Capacitive hygrometers are widely used in industrial and environmental measurements. One of the limitations of these sensors is their temperature dependence. While in temperatures beyond 50 °C the effect has been proven to be significant, for standard conditions in calibration laboratories the magnitude of this dependence has not been rigorously studied. This paper presents the analysis and results of a study of the temperature influence in the calibration of capacitive hygrometers designed for monitoring environmental conditions. Ninety measurements were taken on 15 models of capacitive hygrometers using a two-pressure humidity generator between 30%rh and 80%rh and temperatures from 20 to 30 °C. A three-way analysis of variance (ANOVA) was used to evaluate the data. The results show that the calibration correction is independent of the temperature for the conditions considered; however, there is a correlation between the temperature and the devices, indicating that the gradients in temperature affect each technology of fabrication in a different way.

Abstract:

Effect of temperature and media was studied on seed germination of Prinsepia utilis Royle (bhekal). Germination tests were conducted at four different temperatures viz. 5±1 o C, 15±1 o C, 25±1 o C and ambient room temperature with three germination media viz. top of germination paper (TP), between of paper (BP) and quartz sterilized sand at 90±5% relative humidity in a seed germinator for 21 days. Media and Temperature significantly affected seed traits. Seeds germinated well over wide range of temperature 15±1 o C, to ambient room. Significantly, higher germination percentage, germination value (GV) and minimum mean germination time (MGT) were obtained at 25±1 o C. lower than 25±1 o C and higher temperature (ambient room temperature) had adverse effect on germination of bhekal seeds. Among media, between paper (BP) was found the best in which maximum germination percentage, minimum MGT and maximum GV was recorded. Sand media was found inferior as compared to between and top of paper. Seed germination was unaffected with light.

Abstract:

Heat Recovery Ventilator (VHR) is widely used nowadays as it is capable to maintain high Indoor Air Quality (IAQ) while minimizing the energy loss of indoor air through air-to-air heat exchanger principle. The main component that enables VHR to perform air-to-air heat exchange is known as Paper Heat Exchanger (PP-HEX). Hence, the objective of this research is to study and analyse the performance of a PP-HEX under different return and outdoor air temperatures as well as their effect on both enthalpy and temperature exchange efficiency. Moreover, some numerical models of VHR have been developed to optimize some complex cases and the numerical models are meant to reduce the physical experiments to analyze or improve complex cases in the future. To the best of the authors knowledge, there is no experimental data available from any sources to validate the numerical models. To address this issue, two different supplies of PP-HEX are tested with an actual VHR, and both PP-HEXs will be referred to as PP-HEX-A and PP-HEX-B due to confidentiality. Furthermore, the testing is conducted in a temperature-controlled testing laboratory and the testing conditions are set according to the ISO standard. The preliminary testing results show that the temperature exchange efficiency and enthalpy exchange efficiency of the PP-HEXs have the same trends while the outdoor air temperature is fixed and varying the temperature of indoor air. In contrary, the temperature exchange efficiency and enthalpy exchange efficiency of the PP-HEXs have the same trends while the indoor air temperature is fixed and varying the temperature of outdoor air as well. With the default voltage supplies (240V) to VHR and the setup conditions (according to the ISO Standard) of return air to be 27°C and outdoor air to be 35°C, the testing results show that PP-HEX-A has a temperature exchange efficiency and enthalpy exchange efficiency with a range of (37.97 – 40.28) % and (30.77 – 57.81) % respectively. While PP-HEX-B has a temperature exchange efficiency and enthalpy exchange efficiency with a range of (35.29 – 42.5) % and (39.6 – 55.93) % respectively.

Abstract:

As composite, the mechanical properties of coated fabrics are sensitive to environment. This paper presented mechanical properties under different environments. A list of uniaxial tests are carried out under different temperatures including -20°C, 0°C, 23°C, 50°C, and 70°C. First, the tensile behaviors at room temperature and the failure behaviors are studied. Then, the effects of temperature on mechanical properties are determined. Finally, the effects of water immersion on mechanical properties are discussed. Results show PTFE coated fabrics remained unchanged in varying temperature and humidity. The temperature has effects on the mechanical properties of PVC coated fabrics. With increasing temperature, the strength decrease and the strain at break increase. The temperature induction factors are proposed for the design and analysis. The water immersion has little effect on the mechanical properties because of the impervious coating.

Abstract:

Abstract Piglets are born wet, and evaporation of that moisture decreases body temperature, increasing the mortality risk. The objective of this study was to compare the effect of 2 commercially-applicable piglet drying methods on rectal temperature over 24 h after birth. The study was carried out at a commercial sow facility using a CRD with 3 treatments: Control (piglets not dried); Desiccant (piglets dried at birth using a cellulose-based desiccant); Paper Towel (piglets dried at birth using paper towels). Piglets were weighed at birth and individually identified with a numbered ear tag. Rectal temperature was measured at 0, 10, 20, 30, 45, 60, 120, and 1440 min (24 h) after birth. Sows and litters were randomly allotted to treatments. Data were analyzed using a repeated measures model with PROC MIXED of SAS. Litter was the experimental unit and piglet was a subsample of the litter; the model included the fixed effects of treatment and repeated time, and the interaction. There was no effect (P > 0.05) of treatment on rectal temperature at birth, or at 10 min or 24 h after birth. The Desiccant and Paper Towel treatments had greater (P < 0.05) temperatures than the Control at all times of measurement from 20 to 120 min after birth. Piglets on the Desiccant treatment had greater (P < 0.05) temperatures than those on the Paper Towel treatment between 30 and 120 min after birth. In conclusion, drying piglets at birth with either a desiccant or paper towels increases rectal temperatures between 20 and 120 minutes after birth, with the greatest effect being for the desiccant. Further research is needed to compare other methods of increasing piglet temperature and to determine if drying of piglets impacts pre-weaning mortality. This research was funded by the National Pork Board.

Abstract:

Abstract Asphalt pavement is under different climatic conditions throughout its service life, which means that fatigue cracking does not occur at a specific temperature, but at a temperature range. The main objective of this paper is to evaluate the influence of different temperatures in the fatigue life of two asphalt binders: a non-modified binder (penetration grade 30/45) and a highly polymermodified binder (HPMB). The fatigue resistance characterization was performed by means of a linear amplitude sweep (LAS) test at the temperatures of 10, 15, 20, 25, and 30°C using a dynamic shear rheometer (DSR). From the dynamic shear modulus (|G*|) results, adhesion loss was observed between the binder and the rheometer parallel plate at the lower temperature of 10°C,while at higher temperatures (25 and 30°C) plastic flow was observed rather than fatigue damage. Therefore, considering that the actual test procedure does not specify the testing temperature, the evaluation of failure mechanism is essential to validate test results, because the random selection of test temperature might lead to inconsistent data.

Full text

Abstract:

In terms of content, the paper is aimed at analysing and comparing the quality of fresh green hops and hops dried at two drying temperatures – 55°C (in the traditional manner) and 40°C (using the so-called gentle drying), regarding the maximum preservation of hop essential oils. Comparative experiments were carried out in an experimental chamber dryer with two Czech hop cultivars Saaz and Harmonie. The moisture content of hops at the beginning of drying was 75% and at the end of drying it was 9–10%. By lowering the drying temperature from 55°C to 40°C, the drying time in cv. Saaz prolonged from 8 to 10 h and for the cv. Harmonie from 9 h to 12 h. Compared to fresh hops, the amount of hop oils decreased by 10% when dried at 40°C and by 36% (cv. Saaz) and 43% (cv. Harmonie) when dried at 55°C. These losses can be considered significant, especially for hops intended for late and dry beer hopping. However, by drying the hops at different temperatures, the ratios between various components of the essential oils and thus also their sensory character remained approximately unchanged. Due to the reduced amount of essential oils, the drying effect reduces the intensity of hop aroma depending on the drying temperature.

Full text

Abstract:

Static and dynamic mechanical properties of concrete are affected by temperature effect in practice. Therefore, it is necessary to investigate the corresponding influence law and mechanism. This paper demonstrates the variation of mechanical properties of concrete at temperatures from −20°C to 60°C. Temperature effects on cube compressive strength, splitting tensile strength, prism compressive strength, modulus of elasticity, and frequency are conducted and discussed. The results indicate that static mechanical properties such as compressive strength (cube and prism), splitting tensile strength, and modulus of elasticity have highly linear negative correlation with temperature; this law is also applied to the first order frequency of concrete slab. The coupling effect of temperature and damage on change rate of frequency reveals that temperature effect cannot be ignored in damage identification of structure. Mechanism analysis shows that variation of elastic modulus of concrete caused by temperature is the primary reason for the change of frequency.

This paper studies the thermal effect on dynamic stability of single-walled carbon nanotubes (SWCNTs) embedded in polymer matrix in low and high temperatures under impact loads. To this end, we present a nonlocal elastic shell model including thermal and small-size effects. Further, numerical calculations are presented for SWCNTs. Results show that the increasing in temperature field has the effect of increasing the dynamic buckling loads at low or room temperature. However, this effect leads to decrease the dynamic buckling loads at high temperature. In addition, it is observed that nonlocal dynamic buckling loads increase by an increase in the Neperian frequency.

Abstract:

The hot pressing parameters and fiber ratio have an important influence on the dielectric properties of aramid insulating paper. In order to deeply explore its influence and the mechanism behind it, aramid insulating papers were made with different hot pressing temperatures and pressures as well as fiber ratios. Its tightness, dielectric constant, and AC breakdown strength were tested, and its microstructure was analyzed by scanning electron microscopy. It was found that with an increase in hot pressing temperature, pressure, and fibrid content, the overall dielectric constant of the insulating paper showed a slight upward trend, while the tightness and AC breakdown strength continued to increase. Hot pressing temperature and pressure have a synergistic effect on the dielectric properties of insulating paper. The effects of these two parameters on the dielectric properties of insulating paper are similar, while the AC breakdown strength is greatly affected by the fiber ratio. In this paper, the influence mechanism by which the microstructure and fiber crystallinity of insulating paper is affected in the hot pressing process is discussed.

Full text

Abstract:

Abstract It is well established that temperature variability affects a range of outcomes relevant to human welfare, including health, emotion and mood, and productivity across a number of economic sectors. However, a critical and still unresolved empirical question is whether temperature variation has a long-lasting effect on economic productivity and, therefore, whether damages compound over time in response to long-lived changes in temperature expected with climate change. Several studies have identified a relationship between temperature and gross domestic product (GDP), but empirical evidence as to the persistence of these effects is still weak. This paper presents a novel approach to isolate the persistent component of temperature effects on output using lower frequency temperature variation. The effects are heterogeneous across countries but collectively, using three different GDP datasets, we find evidence of persistent effects, implying temperature affects the determinants of economic growth, not just economic productivity. This, in turn, means that the aggregate effects of climate change on GDP may be far larger and far more uncertain than currently represented in integrated assessment models used to calculate the social cost of carbon.

Abstract:

Mesophilic and thermophilic digestion of wastewater sludges from the forest industry were studied in semicontinuous flow reactors. Laboratory scale reactors were used for anaerobic treatment studies of a mixture of primary and secondary sludges from a CTMP mill. The VSS reductions in mesophilic and thermophilic digestion of combined CTMP sludge were 41 and 36%, respectively. Specific gas production in the mesophilic process was 0.09 m3/kgVSS added or 0.38 m3/kgVSSreduced. In thermophilic digestion the respective numbers were 0.05 and 0.13. The mesophilic digestion process was stable at an organic loading rate of 2.5 kgVSS/m3d, which represents a 15 days retention time. The supernatant quality of thermophilic digestion was poor (CODsol usually between 3000 and 4000 mg/l) compared with the supernatant of mesophilic digestion (CODsol 1000-2000 mg/l.

Abstract:

The ageing of asphalt mixes, together with their exposure to low temperatures, causes a progressive increase of cracking. In this paper, the effect of ageing and temperature on the fatigue of asphalt concretes made with two types of binders, conventional (50/70) and polymer modified bitumen (PMB), is studied. For this purpose, specimens previously subjected to an accelerated laboratory ageing process were tested by a strain sweep test at different temperatures (-5ºC, 5ºC and 20°C). Results were compared with the obtained from the unaged specimens showing the relative importance of ageing, temperature and type of bitumen on the parameters that determine the fatigue life of the mixture. The mixtures behaviour becomes more brittle with ageing and the decrease of temperature. However, ageing hardly has an effect on fatigue at lower temperatures. In general, mixtures made with polymer modified bitumen have a better fatigue performance to ageing and temperature.

Abstract:

This paper describes a quick approach for quantification of the effects of a chemical warm named Rediset, and its interactions with temperature and aging on the rheological properties of asphalt binders using Response Sur-face Method. The central composite method was applied to design experimental programs for three test temperature conditions, namely; very high temperature (120–180 °C), high temperature (46–82 °C), and intermediate temperature (19–31 °C). Rotational viscosity, G*/sin δ and G*sin δ were selected as parameters to assess the effects of the chemical warm additive on the rheological properties of asphalt binders for different aging conditions. Evaluation of the effects of this additive on the transformed value of G*/sin δ at high temperatures indicates that additive content has significant effect on Ln(G*/sin δ). The results for intermediate temperatures show that this additive has a positive effect on G*sin δ of asphalt binders.

Abstract:

In this paper we discuss the temperature dependence and its effect on surface roughness. In abrasive flow machining (AFM) process the temperature of media rises drastically due to procedure of being sheared. To examine the effect of media temperature on surface roughness, an experiment system with the functions of controlling, measuring and recording temperature is set up. The variable trend of media temperature is revealed during AFM. Experiments are performed at different temperatures. Experimental results show that the media at high temperature results in less improvement in surface roughness. Therefore the media can have good machining performance in the first few cycles and the media temperature rise rapidly. Finally we conclude that the best workable temperature should be below 25 °C during the AFM.

Abstract:

Thermal barrier coatings (TBC) are designed to reduce the temperatures at the surface of metallic hot working pieces. A new refractory enamel, denoted RE_20, was developed at INCAS SA. The RE_20 is designed to protect pieces made of EI 468 superalloys. Thermal barrier effect (TBE) is frequently used in the literature to refer to the temperature decreasing at the heat exposed surface, but it is not defined as a quantitative measurand. The paper aims to mitigate this shortcoming by introducing two measurands for a proper assessment of the TBE i.e. relative temperature decreasing (RTD) and relative heat flow decreasing (RHD). The TBE depends on the working temperature, therefore it has to be estimated at elevate temperatures in the 900-1100oC range. This is possible only through thermal diffusivity flash method (ThDM) which facilitates measurements up to 1000oC. Two mathematical models were derived for RTD and RHD. The models were applied to the RE_20/ EI868 systems for two cases: as obtained and as cyclic thermal shock tested at 900oC. The paper addresses the following novelties: two new measurands (RTD, RHD), the TBE behavior depending on the working temperature and the TBE dependance on upper temperature of the thermal shock.

Abstract:

The application temperature range of temperature memory effect (TME) in deformed TiNi alloys was studied in this paper. The TME could be used in a wider temperature range when the specimen cold-rolled in a high deformation. And, the “highest” application temperature of TME could increase with the deformation, and finally rise to 573K with deformed 30%. This temperature no longer changes in higher deformations, while the characteristic of TME still increase with the deformation below 573K. This is due to the dislocation texture and deform-induced martensite structures restrain the reverse martensite transformation. And the restraint disappears when specimens are annealed more than 573K.

Abstract:

Gasification is one of the technologies for utilization of biomass. Gasification is a transformation process that converts solid fuels into gaseous fuels. The gaseous fuel may be subsequently applied in other technologies with all the benefits that gaseous fuels provide. The principle of biomass gasification is a common knowledge. It is thermochemical decomposition oof the fuel in presence of gasification agent. Heat from the endothermic reaction is obtained by a partial combustion of the fuel (autothermal gasification) or the heat is supplied into a gasifier from the outside (allothermal gasification). Oxygen for the partial combustion is supplied in the gasification medium. Quality, composition and amount of the producer gas depend on many factors which include type of the gasifier, operating temperature and pressure, fuel properties (moisture content) and type and amount of gasification medium. Commonly, air, steam and oxygen and their combinations are used as a gasification medium. Every kind of gasification agents has its significant advantages and disadvantages.Research and analysis of the gasification process must pay special attention to all operating parameters which affect quality and amount of the producer gas that is the efficiency of the conversion itself. Composition of the producer gas, calorific value, and content and composition of impurities are especially observed as these are the basic characteristics directly affecting subsequent application of the gas. Steam addition has a significant impact on gas composition. Steam decomposition into hydrogen and oxygen, and their subsequent reactions increases amount of combustibles, hydrogen, methane and other hydrocarbons. Steam addition in the gasification also affects amount and composition of tar and has a negative impact on heat balance.Energy Institute at the Brno University of Technology has a long tradition in research of biomass gasification in atmospheric fluidized bed reactors. Air was used as a gasification medium. This paper describes our experience with gasification using a mixture of air and steam. We analysed the whole process and in this paper we wish to describe the impact of temperature on outputs of the process, especially temperature of leaving steam and temperature of gasification reactions.

Abstract:

Asphalt mixtures have a highly sensitive and dependent on temperature. The typical modulus values of asphalt mixtures vary dramatically at different temperatures. Therefore, adjusting the modulus values of asphalt pavements of different testing temperatures to that of the criterion temperature condition is an important task to sustain asphalt mixtures modulus based the structural bearing capacity estimation of asphalt pavements comparable between time and space. According to the dynamic finite element numerical analysis method and the multivariate nonlinear regression analysis technique, the paper firstly established the back calculation model of asphalt mixtures modulus in term of the relationship between asphalt moduli and deflection basin parameters. Secondly, considering the correlation between the temperature at the middle of asphalt wearing course and the asphalt mixture modulus, the conversion analysis procedure of asphalt mixtures moduli of different temperatures was presented based on BELLS3 temperature adjustment coefficient method. Finally, the in-service monitoring over the existing pavements was conducted to test the validity of the procedure. The research provides a practical basis for evaluating pavement performance of asphalt wearing mixtures and a theory support for overlaying thickness design of asphalt pavements.

The results suggested that the SiNWs length could be controlled easily by the change of the etching temperature. Superlong SiNWs were also fabricated by this technique. The superlong SiNWs had the length more than 400 μm and the aspect ratios were about 2000-20000, which could be applied in nanosensors and interconnection.

Abstract:

Plasma-assisted catalytic cracking is an attractive method for producing biofuels from vegetable oil. This paper studied the effect of reactor temperature on the performance of plasma-assisted catalytic cracking of palm oil into biofuels. The cracking process was conducted in a Dielectric Barrier Discharge (DBD)-type plasma reactor with the presence of spent RFCC catalyst. The reactor temperature was varied at 400, 450, and 500 ºC. The liquid fuel product was analyzed using a gas chromatography-mass spectrometry (GC-MS) to determine the compositions. Result showed that the presenceof plasma and catalytic role can enhance the reactor performance so that the selectivity of the short-chain hydrocarbon produced increases. The selectivity of gasoline, kerosene, and diesel range fuels over the plasma-catalytic reactor were 16.43%, 52.74% and 21.25%, respectively, while the selectivity of gasoline, kerosene and diesel range fuels over a conventional fixed bed reactor was 12.07%, 39.07%, and 45.11%, respectively. The increasing reactor temperature led to enhanced catalytic role of cracking reaction,particularly directing the reaction to the shorter hydrocarbon range. The reactor temperature dependence on the liquid product components distribution over the plasma-catalytic reactor was also studied. The aromatic and oxygenated compounds increased with the reactor temperature.©2020. CBIORE-IJRED. All rights reserved

The effect of different factors, such as carbon fiber content, temperature, electrifying time and frequency, power density on the electrothermal properties of the composite papers with different carbon fiber content was researched. The results show that the resistivity of the composite papers decreases with the increasing of carbon fibers. The current-voltage relationship is in good conformity with the Ohm's law. The negative temperature coefficient and good reversibility are shown during the heated and cooled process of the papers. The resistance of the papers decreases gradually with electrifying time and trends to stable after several hours. On-off electrifying times on its resistance have little effect in the long term. The curve of power density and surface temperature shows a good linear behavior.

In this paper the results of recent studies on the application of lower critical solution temperature (LCST) phenomena of polymer solutions to the surface modification of flat and spherical substrates are reported. It has been found that controlled polymer deposition can be achieved at temperatures exceeding LCST. The obtained polymer coating exhibits a peculiar surface morphology and, if particles are introduced, can be highly effective in pigment dispersions stabilizing. It has been established that the temperature induced polymer deposition can be carried out as the finely dispersed component precipitation on the substrate surface that goes along with the polymer deposition at temperatures exceeding LCST, which in its turn allows to modify the pigments surface when finely dispersed additives are incorporated into the surface modifying coating.

Abstract:

The concrete filled steel tubular (CFST) structure takes full advantages of the interaction of two materials in the process of loading, while the thermal performance parameters between steel tube and concrete are different, and the outside temperature changes makes the structural section produce a greater temperature gradient, which leads to the uncoordinated deformation between them. In this paper, the thermal conductivity of experimental system is carried on the theoretical analysis, then the distribution regularities of sectional temperature are obtained through the testing its of CFST under variable temperature effect, and the larger temperature difference will produce the temperature stress, which affects the bonding performance of structural interface. So in order to better analyze the influence which is impacted on the mechanical performances of structure by the combination effect of multiple factors such as temperature and load, such paper can provide the theoretical and experimental foundation.
