Study on Thermal Performance Measurement and Construction of Passive Exterior Wall with Low Energy: Teaching and Laboratory Building of Shandong Jianzhu University

It can provide theoretical support for the optimal design of low-energy walls by measuring the actual thermal conditions inside the walls of passive low-energy buildings and studying the rationality of the wall structure design.Taking the teaching and laboratory building of shandong jianzhu university as an example, this paper explores the method of using temperature and humidity sensor to measure the air temperature and humidity inside the wall to represent the solid temperature and humidity of the wall.Based on the measured data and calculation results, the rationality of the structure of the test external wall is analyzed from four aspects: the performance of insulation, the moisture drain performance of wall, the ability of preventing the penetration of the hot and humid air of the inner wall, and the waterproof performance of the outer wall.Results show that the external wall structure of polystyrene board (200 mm thick) for external insulation and thin plastering has good practical operation effect in three aspects of thermal insulation, internal moisture discharge, and external wall waterproof, which basically meets the design requirements of external wall of passive house in germany.In terms of moisture protection of the inner wall, the inner wall of cement mortar (15 mm thick) may not be able to effectively prevent the infiltration of indoor hot and humid air.Thus, the insulation layer should be added into the external wall.In addition, the moisture inside the wall is obviously affected by the season.The drain performance of moisture inside the wall mainly occurs in the sweltering heat, and the drain direction is from the indoor side to the outdoor side.In the external insulation structure, there are two layers of graphite polystyrene plate (100 mm thick), and the insulation effect of polystyrene plate near the outdoor side is better than that near the indoor side.The combination of anticrack mortar (5 mm thick) and paint cannot completely prevent the infiltration of rainwater, but the infiltration of rainwater in the wall will be quickly discharged in a short time.

A Comparative Study on Crack-Healing Ability of Al2O3/SiC Structural Ceramic Composites Synthesized by Microwave Sintering and Conventional Electrical Sintering

This study was conducted to assess and compare the crack‐healing ability of conventional electrical sintered and microwave sintered al 2 o 3 / x wt.% si c ( x = 5, 10, 15, and 20) structural ceramic composites.The crack‐healing ability of both conventional electrical sintered and microwave sintered specimens was studied by introducing a crack of ∼100 μ m length by vickers’s indentation and conducting a heat treatment at 1200°c for dwell time of 1 h in air.The flexural or bending strength of sintered, cracked, and crack‐healed specimens was determined by three‐point bending test, and the phase variations by x‐ray diffraction and sem micrographs before and after crack‐healing of both the sintering methods were studied and compared.The results show that almost all the specimens recovered their strength after crack‐healing, but the strength of microwave sintered al 2 o 3 /si c structural ceramic composites has been shown to be better than that of conventional electrical sintered al 2 o 3 /si c structural ceramic composites.The microwave sintered crack‐healed al 2 o 3 /10 wt.% si c specimen shows higher flexural strength of 794 mpa, which was 105% when compared with conventional electrical sintered al 2 o 3 /10 wt.% si c and crack‐healed al 2 o 3 /10 wt.% si c specimen.It was found by x‐ray diffractogram that before crack‐healing, all the conventional electrical sintered samples have si o 2 phase which reduce the crack‐healing ability and microwave sintered samples with 15 and 20 wt.% si c show lesser si o 2 phase and 5 and 10 wt.% si c samples have no si o 2 phase before crack‐healing.However, after crack‐healing treatment, all the samples have distinct si o 2 phase along with al 2 o 3 and si c phases.Microwave sintered al 2 o 3 /10 wt.% si c specimen cracks were fully healed which was evident in sem micrographs.

Kinetics of Sludge Superheated Steam Drying and Optimization of Process Parameters

The purpose of this paper is to study the effects of steam temperature, sludge thickness, and steam flow on the drying characteristics and drying kinetics of sludge superheated steam and optimize the process parameters of sludge superheated steam drying by using the response surface method and taking relative unit energy consumption as the response value.Single-factor test of superheated steam drying of sludge was conducted under different drying conditions of steam temperature (180, 195, 220, and 260°c), sludge thickness (2, 3.5, 6, and 10 mm), and steam flow rate (22, 29, 36, and 40 m3/h).Taking relative unit energy consumption as the response value and steam temperature, sludge mass (corresponding to sludge thickness), and steam flow as the test factors, the three-factor and five-level response surface test was conducted on the sludge.The experimental results show that steam temperature and sludge thickness had a significant influence on the drying characteristics of superheated sludge steam ( p &lt; 0.05 ).With the increase of steam temperature, the decrease of sludge thickness, and the increase of steam flow, the drying time of sludge will be shortened, the drying efficiency of sludge will be improved, and the maximum condensation amount and recovery time will be reduced.The quadratic polynomials, linear equation, and logarithmic model can better fit the change law of water variation of the sludge of superheated steam condensation section, recovery section, and drying section.With the increase of steam temperature, sludge thickness, and steam flow rate, the effective diffusion coefficient also increases.The activation energy of sludge superheated steam drying was 13.42 k j/mol at a sludge thickness of 6 mm, steam flow rate of 22 m3/h, and different steam temperatures.The order of influence degree of three test factors on relative unit energy consumption is as follows: sludge mass (corresponding to sludge thickness) &gt; steam flow rate &gt; steam temperature.According to response surface test analysis, the optimal drying process with relative unit energy consumption is steam temperature of 215°c, sludge mass of 25 g (corresponding sludge thickness of 8 mm), and steam flow of 30 m3/h.Under this drying process parameter, the minimum energy consumption of sludge superheated steam drying is 284.61 k j/g.Compared with the relative unit energy consumption value obtained in the verification test, the relative error is 1.65%.

Preparation of Mg2Ni Hydrogen Storage Alloy Materials by High Energy Ball Milling

In this paper, mg2ni hydrogen storage alloy powder was prepared by high-energy ball milling mechanical alloying method, and the influence of stirring shaft rotation speed, ball milling time, and different sizes of ball mills on the formation time, powder morphology, and crystal structure of mg2ni alloy during ball milling was studied.The results show that the mg2ni alloy was obtained by high-energy ball milling in this work, and the efficiency was increased by about 76% compared with the traditional ball milling method.In the case of higher rotational speed or larger blades, the time to generate mg2ni alloy can be advanced, the alloying process can be shortened, and mg2ni alloy with a particle size of less than 10 um can be obtained.However, after the ball milling reaches a certain time, the cold welding and crushing of the alloy powder reach a balance, and the particle size is basically unchanged.The hydrogen storage alloy was activated, the hydrogen storage pct curve was detected, and the hydrogen absorption kinetic curve and the pct curve were analyzed.After ball milling at 900/1100 rpm for 13 hours, a mg2ni alloy with a single composition, extremely low impurity content, and partially amorphous and nanocrystalline coexistence was obtained.Its mass hydrogen storage density also reached the theoretical value of 3.6 wt%.

A negative feedback loop between long noncoding RNA NBAT1 and Sox9 inhibits the malignant progression of gastric cancer cells

Long noncoding rnas (lnc rnas) play critical roles in carcinogenesis and progression, and act as important gene expression modulators.Recent evidence indicates that lnc rna neuroblastoma associated transcript 1 (nbat1) functions as a tumor suppressor in some types of human cancers.However, its functional role in the development of gastric cancer (gc) remains unknown.The aim of this research was to investigate the clinical significance and biological functions of nbat1 in gc.Nbat1 was found to be significantly down-regulated in gc tissue.Decreased nbat1 expression was correlated with poor differentiation, higher tumor stage and lymph node metastasis, and poor prognosis.Functional assays showed that nbat1 inhibited gc proliferation, migration, and invasion.Nbat1 also suppressed proliferation, migration, and capillary tube formation of human umbilical vein endothelial cells (huvecs).Mechanistically, nbat1 interacted with sox9, and reduced its protein stability by promoting it from polyubiquitination and proteasome-dependent degradation.Moreover, we revealed that sox9 could occupy the nbat1 promoter to inactivate its transcription.The negative feedback loop of nbat1 and sox9 continuously enhanced the suppressive effects.In conclusion, these findings suggest that feedback regulation of nbat1 and sox9 served as a critical effector in gc progression.

Cucurbitacin E inhibits osteosarcoma cells proliferation and invasion through attenuation of PI3K/AKT/mTOR signalling pathway

Cucurbitacin e (cu e), a potent member of triterpenoid family isolated from plants, has been confirmed as an antitumour agent by inhibiting proliferation, migration and metastasis in diverse cancer.However, the effects and mechanisms of cu e on osteosarcoma (os) have not been well understood.The present study aimed to test whether cu e could inhibit growth and invasion of os cells and reveal its underlying molecular mechanism.After various concentrations of cu e treatment, the anti-proliferative effect of cu e was assessed using the cell counting kit-8 assay.Flow cytometry analysis was employed to measure apoptosis of os cells.Cell cycle distribution was analysed by propidium iodide staining.Transwell assay was performed to evaluate the effect of cu e on invasion potential of os cells.The protein levels were measured by western blot.In addition, the potency of cu e on os cells growth inhibition was assessed in vivo.Our results showed that cu e inhibited cell growth and invasion, induced a cell cycle arrest and triggered apoptosis and modulated the expression of cell growth, cell cycle and cell apoptosis regulators.Moreover, cu e inhibited the pi3k/akt/m tor pathway and epithelial–mesenchymal transition (emt), which suppressed the invasion and metastasis of os.In addition, we also found that cu e inhibited os cell growth in vivo.Taken together, our study demonstrated that cu e could inhibit os tumour growth and invasion through inhibiting the pi3k/akt/m tor signalling pathway.Our findings suggest that cu e can be considered to be a promising anti-cancer agent for os.

Protective Effects of Prunasin A against the Differentiation of Osteoclasts and Destruction of Cartilage via the Receptor Activator of Nuclear Factor-Kappa-Β Ligand/Mitogen-Activated Protein Kinase/Osteoprotegerin Pathway in a Rat Model of Arthritis

The present study evaluated the protective effects of pseurotin a against inflammation and the destruction of cartilage in a rat model of rheumatoid arthritis (ra).Ra was induced by intradermal injections of freund’s complete adjuvant (1 mg/m l), and the treatment with pseurotin a (50 and 100 mg/kg, p.o.) was administered over 1 week.The effects of pseurotin a were assessed by estimating hind paw volume (hpv) and determining the levels of inflammatory mediators in the serum and synovial fluid of collagen-induced arthritis (cia)-induced ra rats.Western blot and histopathological assays were performed to assess changes in synovial tissues.Additionally, in vitro analyses of receptor activator of nuclear factor-kappa-β ligand (rankl)-stimulated raw264.7 cells treated with pseurotin a at different concentrations (1, 10, and 100 μg/m l) were conducted to assess the effects of pseurotin a on apoptosis ratio, real-time polymerase chain reaction data, and tartrate-resistant acid phosphatase staining.Compared to the ra group, treatment with pseurotin a significantly decreased hpv and reduced the levels of inflammatory mediators in the synovial fluid and blood.Additionally, pseurotin a ameliorated the protein expressions of osteoprotegerin, nuclear factor of activated t-cells, nuclear factor-kappa beta (nf-κb), iκbα, extracellular signal regulated kinase, and p38 as well as histopathological changes in the synovial tissue of cia-induced ra rats.The in vitro findings revealed that pseurotin a treatment did not alter the apoptosis ratio in rankl-stimulated raw264.7 cells but significantly reduced the m rna expressions of calcitonin receptor, nf-κb, and matrix metallopeptidase-9.The present findings suggest that pseurotin a ameliorated the differentiation of osteoclasts and the destruction of cartilage in ra rats via regulation of the mitogen-activated protein kinase/rankl/nf-k b pathway.
