Intragastric administration of AMG517, a TRPV1 antagonist, enhanced activity-dependent energy metabolism via capsaicin-sensitive sensory nerves in mice
Authors: Hai Jun , Kawabata Fuminori , Uchida Kunitoshi , Nishimura Shotaro , Tabata Shoji
Published: July 2020

Transient receptor potential vanilloid 1 (TRPV1), a nociceptive cation channel, is known to play roles in regulating the energy metabolism (EM) of the whole body. We previously reported that TRPV1 antagonists such as AMG517 enhanced EM in mice, however, these mechanisms remain unclear. The aim of this study was to explore the mechanisms underlying the enhancement of EM by AMG517, a selective TRPV1 antagonist, in mice. Respiratory gas analysis indicated that intragastric administration of AMG517 enhanced EM along with increasing locomotor activity in mice. Next, to clarify the possible involvement with afferent sensory nerves, including the vagus, we desensitized the capsaicin-sensitive sensory nerves of mice by systemic capsaicin treatment. In the desensitized mice, intragastric administration of AMG517 did not change EM and locomotor activity. Therefore, this study indicated that intragastric administration of AMG517 enhanced EM and increased locomotor activity via capsaicin-sensitive sensory nerves, including vagal afferents in mice.
When COVID-19, constitutional crisis, and political deadlock meet: the Israeli case from a disproportionate policy perspective
Authors: Maor Moshe , Sulitzeanu-Kenan Raanan , Chinitz David
Published: July 2020

This article describes the efforts made by the Israeli government to contain the spread of COVID-19, which were implemented amidst a constitutional crisis and a yearlong electoral impasse, under the leadership of Prime Minister Benjamin Netanyahu, who was awaiting a trial for charges of fraud, bribery, and breach of trust. It thereafter draws on the disproportionate policy perspective to ascertain the ideas and sensitivities that placed key policy responses on trajectories which prioritized differential policy responses over general, nation-wide solutions (and vice versa), even though data in the public domain supported the selection of opposing policy solutions on epidemiological or social welfare grounds. The article also gauges the consequences and implications of the policy choices made in the fight against COVID-19 for the disproportionate policy perspective. It argues that Prime Minister Netanyahu employed disproportionate policy responses both at the rhetorical level and on the ground in the fight against COVID-19; that during the crisis, Netanyahu enjoyed wide political leeway to employ disproportionate policy responses, and the general public exhibited a willingness to tolerate this; and (iii) that ascertaining the occurrence of disproportionate policy responses is not solely a matter of perception.

Authors: Dziob Daniel , Čepič Mojca
Published: July 2020

Heat transfer is a phenomenon well known from everyday life. It is intuitively connected to the properties of materials, that is, to the physics concept of thermal conductivity relevant for cooking or maintaining the constant temperature in rooms, even without being familiar to the underlying physics. However, measurement of thermal conductivity is usually demanding, but here we present a simple, quick, and almost hands-on method that yields quite accurate values for thermal conductivity of insulating and semi-insulating materials, appropriate for a classroom setting.
Interfacial flow dynamic micro-response and spatiotemporal evolution of flow pattern for thermocapillary–buoyancy convection in a liquid bridge
Authors: Yang Shuo , Deng Qiaosheng , Xu Youning
Published: July 2020

Compared with the former studies, the perturbation behavior of thermocapillary–buoyancy convection caused by the simultaneous coupling response of the microscale surface flow, free surface deformation and spatiotemporal evolution of flow patterns is revealed by the combination of experimental and numerical methods for the first time. The free surface morphology transforms from the ‘Ƨ’-shape into the twisted ‘M’-shape in the corresponding balanced stage of thermocapillary–buoyancy convection (at t = 975, Bod = 251.5), and eventually becomes ‘Ƨ’-shape in the corresponding third stage (Bod = 229.9). Meanwhile, there is a weak response of the free surface flow during each transition stage accompanied by periodic hydrothermal waves. The perturbation characteristics of the velocity, the temperature and the transverse location of surface flow are the most prominent at the intermediate height of liquid bridge (y = 0.2). The characteristic of longitudinal velocity mainly presents as the pulsation, while there is also the pulsation inside the oscillation of transverse velocity with the large amplitude (the oscillating period of 2f

u
= 7.2 s and the amplitude of A

u
= 0.0057). The periodic characteristic of temperature oscillation is obvious (2f
θ = 0.2 s, A

Published: July 2020

Litopenaeus vannamei shrimp is a type of aquaculture shrimp, easily maintained in fresh water, short-lived, at a lower cost compared to other types of shrimp cultivation. So vannamei shrimp is more available in traditional markets. The cultivation of vannamei shrimp uses fisheries technology in its feed, which is a cuprum (Cu) mixture. The study was conducted by taking samples of Litopenaeus vannanmei species purchased in 8 traditional markets spread throughout the city of Surabaya. Each market is taken 5 random samples of shrimp with relatively the same size and condition. Then it is processed by steaming, boiling, frying and burning. Determination of Cu heavy metal content in shrimp is carried out using atomic absorption type AA 3e00 Variant Tech tron (AAS), with a few additional 50 ml glass cups, 10 ml volumetric flask, 5 ml polyethylene vial, 10-100 effendorf micropipette μl and analytical balance. There was a significant difference between boiling (p = 0,000) and steamed (p = 0,001) with shrimp in raw conditions. Whereas for processing by grilling (p = 0.989), and by frying (p = 0.078) showed insignificant results. This means that there is no significant difference in Cu content in shrimp, between raw conditions and processing by being grilled and fried.

Waste management and domestic liquid waste residual household activities such as bathing, washing, and defecation were not done well along the Ciliwung river, causing water quality to decline. Residents of Kampung Tanah Rendah, Kampung Melayu, East Jakarta, is still free-throw garbage and domestic household waste into the Ciliwung River. Waste management is not unified and usually carried by an individual or group by using the tool carrier in the form of a cart. Waste transportation costs are paid by the voluntary contributions of citizens. Most residents do not have bathroom facilities at home are reluctant to use latrines and still perform a routine to defecate on a bamboo raft floating raft river or familiarly called. Inspired by the citizens raft (getek) used for bathing, washing and activity, defecation, trash, and interact in Ciliwung, people consisting of adults and children are invited to get to know various kinds of water pollution. Adopting an idea of things that a citizen of the existence of the Ciliwung River on the raft, then made a scientific introduction of alternative methods such as “Labtek Apung” that implementation can be done independently or together and anywhere. Tests conducted is a test that is based on visual and organoleptic sensory processes. Parts of organs that play a role in sensing are the eyes as senses of sight, nose, and tongue as the sense of smell as a sensory taster. The scope of experiments on various kinds of water in the village is a test of physics, chemistry, and biological simple to use tools and materials that are easily found in the home. Simple physics test to see the physical shape, smell, color, and taste of the water. Simple chemical testing to see on the water hardness using the tea and simple biological test is performed to determine the existence of microorganisms that live in the water. The introduction of scientific alternatives to the residents, especially the children through these activities, would make scientific terms such as levels of turbidity, acidity, disorders of harmful microorganisms that normally can only be understood by most people with a specific background in the laboratory, to be made easier to understand. It is expected that after this event took place, residents are targeted to raise awareness of environmental problems that occur.

Published: July 2020

Nowadays, one health awareness in the global value chain is increasing. Since, the threat of global occurrence of zoonotic diseases, and pathogens is higher due to global trade. Therefore, the trend of global food trade is driven by food security, sustainable agriculture, and healthy nutrition to foster the long-lasting well-being of the human population. However, food control and biosecurity as proactive and dynamic strategies were not having a clear aim between supporting producers or safeguarding consumers. These aims had a trade-off in policy impact resulting in possible lapses in food production and economic chaos. This paper aimed to describe the food control and biosecurity policy in the global value chain and its impact on global trade. We reviewed the literature on zoonotic diseases, and pathogens related to food production, biosecurity strategies and practices. Then, a comparative analysis was employed and collated with the value chain governance to match its impact on supporting producers or safeguarding consumers. The results show that food control operational designs were inherently supported by biosecurity procedures. Moreover, the international regimes drove awareness, technical capacity and its impact on the policy dynamic in the global trade. The policy in Indonesia concerned more to support producers competitiveness in the global trade, while safeguarding consumers had less attention. This paper concluded that a more balanced policy is needed to implement food control and biosecurity in the global value chain.

Recent The development of power generation capacity is directed to meet the load growth, and in certain areas it is preferred to meet the shortage of electricity supply (RUPTL, 2017). The planned addition of combined generating capacity throughout Indonesia such as coal-fired power plants (CFPP) will dominate the type of power plant to be built, reaching 31.9 GW or 53.0% in the year 2017 to 2026, and by 2019 the addition of very high-power plants reaches 18.7GW. This is in line with the 35,000MW program targeted for completion in 2019. Coal demand continues to increase every year, until the year 2026 reached 152.8 million tons per year. The CFPP operation produce solid waste as Fly Ash and Bottom Ash (FABA) or generally named by Coal Combustion Products (CCPs). Formation of the CCPs in general is 3 - 5% of total coal used, then will required wide land for the placement of FABA product if it cannot be utilized. Characteristics of the CCPs could substitute cement for infrastructure. The utilization of the CCPs in Indonesia still very small amount only 0,47%. Comparative method applied to analyze the regulation in Indonesia with other countries in regulate the CCPs from CFPP. Regulation for CCPs as hazardous waste make some difficulties in utilize the CCPs for construction material. In the other side Indonesia need to build infrastructure with low cost. Through review regulation on determination of FABA from CFPP as hazardous waste could be an effort to increase the utilization of FABA in Indonesia.

Municipal Solid Waste (MSW) has become a major concern currently among ASEAN countries, as the amount of waste generation has increased tremendously. Indonesia generates the highest quantity of municipal waste with 64 million tonnes per year that majority generates from household waste. Each person generates 0,76 kg per day of solid waste. Accordingly, with total population about 264 million, Indonesia would generate waste 200,64 tonnes per day. Indonesia has major policies, programmes, and plans for household waste management, but household waste managements are currently not well-implemented at all domain levels, especially at local level. This study aims to estimate households that manages their domestic waste in not eco-friendly ways in municipal level in Indonesia using EBLUP Fay-Herriot model, that can accommodate small sample domain estimation. It uses household data from the 2017 National Socio-Economic Survey – Social Resilience Module from BPS (SSN17.HANSOS). This study reveals that the highest EBLUP proportion estimation of household waste management in not eco-friendly ways is by open burning (71,85%). There are municipalities with a high proportion of most ways disposing waste in not eco-friendly ways, namely Mamberamo Tengah, Yalimo, and Puncak. The EBLUP SAE approach is more efficient than the direct estimation as is indicated by the lower MSE of EBLUP SAE estimations. Estimating the proportion of households that manage their domestic waste in not eco-friendly ways needs to be done and analysed periodically in order to evaluate whether the municipal waste management programmes are well implemented in local governments.

Published: July 2020

Metro viaduct station construction is a high-risk project in metro construction. In order to make its risk control more effective and the risk management more perfect, scientific and reasonable evaluation is needed. The main risk factors in the construction of metro elevated station are identified by delphi method. Based on this, a risk evaluation index system for the construction of metro elevated station is established, which includes seven first-class indexes: pile foundation construction, cap and equipment excavation, waterproof construction, scaffold erection, formwork construction, cast-in-situ main structure construction, platform and roof structure. The C-OWA operator is used to objectively weigh the indexes, and the extension theory is improved. The construction risk evaluation model of metro elevated station based on C-OWA operator and improved extension theory is constructed, which verifies the scientific rationality of the model. Taking an elevated station project of Qingdao metro as an example, the risk assessment results show that the risk assessment level of the construction of the elevated station of Qingdao metro is relatively high, and the main risk factors are: pile foundation construction, scaffolding erection, formwork construction, cast-in-place main structure construction, and the corresponding improvement suggestions are put forward.

Evaluation and analysis of bias tunnel diseases based on fuzzy mathematics theory
Authors: Liang Huajiang
Published: July 2020

Biased tunnels are subject to the combined effects of vehicle loads, groundwater, atmosphere, and geology during a long period of operation, resulting in the gradual incubation and development of tunnel diseases and tunnel damage. In order to effectively comprehensively evaluate the disease level of the bias tunnel in the operation stage, fuzzy mathematical theory is introduced in this paper. By determining the evaluation indexes of the tunnel disease at all levels, and considering the deterioration effect of the bias on the disease, the bias index is added, and the comprehensive and objective fuzzy operator is used to calculate. The tunnel is evaluated in sections to achieve a more accurate assessment of disease levels. The theory is applied to the disease evaluation of an operating biased tunnel, and a good evaluation result is obtained, This method furtherly perfects the fuzzy comprehensive evaluation system for the disease of biased tunnels.

Published: July 2020

The monitoring, analysis and prediction of surrounding rock deformation during underground tunnel construction is the crucial points of NATM construction. The convergence deformation and vault settlement of surrounding rock of underground tunnel comprehensively reflect the dynamic adjustment process of surrounding rock stress and the supporting effect of supporting structure after tunnel excavation. The observed values can serve as the basis for judging the initial supporting stability of surrounding rock and selecting a reasonable time for secondary supporting. In this paper, the grey theory is implemented to establish the prediction model of the convergence deformation and vault settlement of tunnel surrounding rock. According to field monitoring and grey prediction results, the deformation stability of surrounding rock of underground tunnel is analyzed from two aspects of relative displacement and deformation rate, and the secondary support time is reasonably determined. The analysis results can provide reference for the design, construction and monitoring of similar projects.
Mechanical properties analysis of Angle steel connector of composite bridge with corrugated steel webs
Authors: Shuqinli  , Yang Zhenyu
Published: July 2020

The finite element software Midas FEA was used to simulate and calculate the ultimate bearing capacity, von Mises stress and load-slip curves of the Angle steel connector specimen of the composite bridge with corrugated steel webs. And the ultimate bearing capacity obtained by numerical simulation is compared with the calculated value of the bearing capacity of Angle steel connectors in each specification. The results show that when the ultimate bearing capacity of the specimen is reached, most of the Angle steel is in a state of buckling, all the steel bars are in a state of buckling with deformation, and the concrete pin in the hole is partially damaged. In the specifications, the calculation formula of bearing capacity of Angle steel connector is conservative, the main reason is that the influencing factors of ultimate bearing capacity of Angle steel connector are not comprehensive enough, and the existing formula needs to be further revised.

Authors: Guo Zhongyin , Zhang Shuwei
Published: July 2020

The Qinghai-Tibet Highway is one of the highest highways in the world. Under this special condition, analysing the drivers’ vigilance can help to reduce the traffic accidents. In this paper, the simple reaction time (RT) and the Schulte table test time (ST) of 12 drivers before and after 60 minutes’ driving were collected in the driving simulation experiment done at the altitudes above 3500m. The vigilance indicator VI was established and the optimal scale regression was used to analyse VI and its influencing factors. The study found that the experimental phase and driver age had a significant impact on driver vigilance while the experimental location and experimental period had no significant impact. The driver vigilance of different age groups at the beginning of the experiment was better than that at the end of the experiment. Vigilance of the drivers aged 40 and below at the end of the experiment was better than that of the drivers aged over 40 at the beginning of the experiment. The research results can provide some suggestions for safe driving along Qinghai-Tibet Highway.

Authors: Zhi-peng LI
Published: July 2020

This article introduces the importance of the liquid limit of soil. The liquid limit largely determines the plasticity index and liquidity index of soil, which directly affects the classification and denomination of the soil. It also makes an analysis of the impact of liquid limit on the state of clayey soil and its mechanical indicators. Even if the water content is high and the porosity is large, as long as the water content does not exceed the liquid limit, it cannot be named silt soil. Under the same conditions, the higher the liquid limit, the harder the state of the soil, the higher the undrained strength and bearing capacity, and the smaller the coefficient of consolidation, but the liquid limit has less impact on the compression coefficient and compression modulus.
An Analysis of Influences of Interbasin Water Transfer on Water Resources Carrying Capacity Over Dianchi-Pudu River Basin
Authors: Du Xuanxuan , Chen Jinming , Gu Shixiang , Chen Gang
Published: July 2020

This paper adopts the maximum carrying population, industrial added value and agricultural irrigation area to develop a multi-objective model of water resources carrying capacity (WRCC) in Dianchi-Pudu river basin. The model is used to calculate the WRCC for Dianchi-Pudu river basin in 2020 and 2030 respectively in terms of three different water supply schemes. Results show that except Scheme III which can basically support future socio-economic development and population increase, both Scheme I and II cannot support future socio-economic development and population increase of Dianchi-Pudu river basin. Interbasin water transfer would greatly increase the WRCC of Dianchi-Pudu river basin while efficient water saving can merely work in a limited extent. Consequently, interbasin water transfer and efficient water-saving are the necessaries to guarantee the positive balance between the exploitation of water resource and socio-economic development of Dianchi-Pudu river basin.

China’s “Specifications for Design of Highway Asphalt Highway” have strict regulations on the sideway force coefficient of the highway. The testing system of single-wheel sideway force coefficient, as a common equipment for sideway force detection, has more possession in China and is more widely used. At present, the calibration method of the testing system generally uses the comparison method. The verification methods mentioned in the current verification regulations are mainly for static verification and repeatability inspection. Therefore, at this stage, all measurement verification units cannot reasonably evaluate the accuracy of the instrument. In this paper, through related research and data analysis on the verification method of the testing system of single-wheel sideway force coefficient, it is found that there are problems in the process of equipment verification and calibration, and gives the basis for the development of the calibration equipment, which provides a reference for the establishment of metrological verification standards and traceability of the value of dynamic detection equipment in the industry.
