Authors: Gao Junchai , sun zhen , Shi Mengyuan , Yichi Zhang
Published: November 2022

The spatial positioning model of the fragment perforation on the
randomly scattered target plate in the explosion center coordinate
system after the static explosion of the explosive warhead is
investigated. Assuming that the fragment perforation is formed in the
position of the target plate before static explosion, the principle of
spatial positioning of the randomly scattered target plate is designed.
Combined with coordinate system transformation and plane projective
transformation, the spatial positioning model of randomly scattered
target plate after static explosion is constructed to realize the
spatial positioning of the center of explosion coordinate system for
fragment perforation. Through the simulated scene experiment, the
fragment perforation space coordinates mapped by the target plate
spatial positioning model are given, and the spatial positioning model
of the randomly scattered target plate are verified.
Two-stage demand-side management in energy flexible residential buildings
Authors: Ghazvini Mohammad Ali Fotouhi , Antoniadou-Plytaria Kyriaki , Steen David , Le Tuan
Published: November 2022

In this study, an optimisation model is developed for two-stage energy
management of a residential building to minimise energy cost under
monthly power-based tariffs for peak demand and time variable
electricity prices. The expected peak demand is determined in the first
stage, and then the energy management system minimises the energy cost
in the second stage. The optimisation problem of the second stage is
solved in a rolling time window for the real-time operation of the
flexible energy sources in the building. The optimal charging and
discharging of the battery energy system, the charging of the electric
vehicle battery, the operation of the heating system and the optimal
start times of washing machines and dishwashers are determined close to
real-time. The proposed approach allows the user to determine the
expected peak during the month ahead and try to keep the peak demand in
daily operation below that value using a close to real-time energy
management system. The performance of the two-stage approach for
demand-side management of a residential building has been validated by a
realistic case study.

Published: November 2022

Combining individual movement and home range data can allow us to better
understand how an animal interacts with its surroundings and how this
influences ecological dynamics. Previous studies about the movement and
home range of snakes have shown several factors influencing them.
Usually, these studies were made with different species, using different
methods and in different regions, hampering a comparative analysis to
identify general patterns. The present study aims to review all
available literature about snake movement and home range identifying the
influence of phylogenetic, ecological, and morphological factors on
these behaviors. We conducted an exhaustive survey of specialized
journals and online databases for papers that used radio telemetry to
track snakes. We found 448 papers and after applying filter selected 74
of them to determine the influence of the ecological factors and of the
phylogeny on snake movement and home range in 1010 snakes. Our results
show that movement and home range have no phylogenetic signal, however,
functional traits are linked to snake’s habits and reflect the
particularities of survival strategies and morphologies of each group.
Larger and heavier snakes move more and occupy larger areas. Snake
movement seems to be more efficient in aquatic environments. Our results
provide useful data to understand the dynamics of snake movements and
space use and outline strategies for their conservation.
K-doped CuO/ZnO with Synergistic Dual Active Centers for Highly Efficient Dimethyl Carbonate Synthesis
Authors: Han Han , Ye Xue , Yao Jie , Gao Xinhua , Yu Jinghao , Guo Lisheng , Li jie
Published: November 2022

The application of heterogeneous catalysts in dimethyl carbonate (DMC)
synthesis from methanol is hindered by low activation efficiency of
methanol to methoxy intermediates (CH3O*), which are the key
intermediates for DMC generation. Herein, a catalyst of alkali metal K
anchored on the CuO/ZnO oxide is rationally designed for offering Lewis
acid-base pairs as dual active centers to improve the activation
efficiency of methanol. Characterizations of CO2-TPD，XPS and DRIFTS
revealed that the addition of Lewis base K observably boosted the
dissociation of methanol and combined with Lewis acid CuO/ZnO oxide to
stably adsorb the formed CH3O*, thus synergistically promoted the
transesterification. Finally, the CuO/ZnO-9%K2O catalyst exhibited the
optimal catalytic activity, achieving a high yield of 74.4% with an
excellent selectivity of 98.9% for DMC at a low temperature of 90 °C.
The strategy of constructing Lewis acid-base pairs provides a reference
for the design of heterogeneous catalysts.

Background: Vitamin D deficiency and insufficient in pregnancy can lead to fetal deficiency that may affect chronic disease susceptibility childhood and adulthood. The aim of this study is to investigate the correlation between maternal and neonatal Vitamin D levels at birth and to identify other risk factors among pregnant women in Mongolia. Methods: Hospital-based study was conducted on 528 participants which included 264 mothers and 264 neonates. Pre-delivery maternal blood and neonatal cord blood samples were collected after birth. 25(ОН)D concentration was analyzed in relation to neonatal Vitamin D status, maternal and neonatal characteristics, and maternal Vitamin D intake. Results: The majority of Vitamin D levels in both maternal (76.5%) and neonatal cord (90.5%) blood were in the deficiency range. Only 3.8% of mothers and 1.5% of neonates had levels in the sufficient range at the time of delivery. For maternal demographic factors, total income was significantly different between the groups (P=0.000). The maternal outcomes were no significant associations were found between groups, but neonatal outcomes were associated with maternal Vitamin D status. In terms of Vitamin D supplementation, 27% of women were taken during pregnancy. Of the not supplemented women, 80% were Vitamin D deficient. Conclusions: A high proportion of Vitamin D deficiency was found in both mothers and newborns in our study. There is a strong correlation between the amount of Vitamin D in the mother and in the newborn. A mother’s Vitamin D intake is related to Vitamin D levels in the mother’s blood.

Land subsidence is a phenomenon that occurs in big cities around the world and in Indonesia. Padang as one of the largest cities in West Sumatera also facing land subsidence due to natural phenomena and human induced. Padang City is located at the west coast of Sumatera Island which is the junction point of three active plates that cause frequent earthquakes. Main goals of this research are to know the distribution of area affected by land subsidence, to know the estimated value of land subsidence and to know the value of the velocity of land subsidence in Padang area using DInSAR method. The data used in this study is ALOS PALSAR Image Level 1.1 of Padang city during 2007 to 2010 was obtained through JMRSL CERES Chiba University, Japan and collected through Alaska Satellite Facility website. Differential Interferometric Synthetic Aperture Radar (DInSAR) is a technique considered to be one of the most efficient technique for detecting land subsidence. The DInSAR method is used in mapping altitude changes developed into a land-subsidence map each year. The mapping results show the distribution of the areas affected by the maximum land subsidence in Padang area of West Sumatera are Padang Utara, Nanggalo, and Padang Barat Subdistricts. The land subsidence insignificant occurred is Padang Selatan and Lubuk Begalung Subdistricts. The estimated value of the land subsidence distribution in Padang area using DInSAR method has decreased significantly after the earthquake of September 30, 2009 in Padang Utara, Nanggalo and West Padang Subdistricts is around 0 - 32.70 cm, and the value of land subsidence velocity is around 0.13 - 12 cm/year. One of the expected effects of land subsidence can be increased in the area susceptible for flooding in Padang city.

Authors: Sari Adya Mustika , Syafriani - , Rahmatullah Fajri Syukur
Published: November 2022

The city of Padang is an area severely affected by the earthquake that occurred in the Subduction zone. Earthquakes with large magnitudes greatly affect the damage to buildings, one of the factors that can determine the size of the damage is the peak ground acceleration. The peak ground acceleration and earthquake intensity in Padang City can be calculated using an empirical formula. The research area is on the grid with a distance of 0,02°, in order to obtain 196 calculation points. The empirical formula used is Mc. Guire, Si and Midorikawa, Fukushima-Tanaka, and Donovan which were validated with peak ground acceleration data from accelerographs so as to produce an appropriate empirical formula used to calculate the peak ground acceleration value in Padang City. From the validation process it was found that the Fukushima-Tanaka formula is the appropriate formula used to calculate the peak ground acceleration value in the city of Padang with the lowest average error percentage. The results of the calculation show that the highest peak ground acceleration value is in Bungus Teluk Kabung District, which is 69-73 gal, while the lowest peak ground acceleration value is in Koto Tangah District, which is 60-65,5 gal. Based on the peak ground acceleration value, it is known that the intensity of the earthquake in Padang City has a scale of VI MMI.

Published: November 2022

In general, the population in Indonesia is a farmer. This causes farmers to need information about the weather to carry out agricultural activities. One way to obtain information about the weather is to use the Rain Gauge instrument. In this study, the Rain Gauge instrument at LAPAN Kototabang from 2020 to 2021 was compared with the Optical Rain Gauge instrument. This research uses descriptive research with secondary data in the form of rainfall intensity data that has been measured on the Rain Gauge and Optical Rain Gauge from LAPAN Kototabang. This research was conducted to analyze the output data from the Rain Gauge and Optical Rain Gauge in the form of rainfall intensity, rainfall accumulation, and time. From the data analysis, two results can be stated from this research. First, the analysis of the rainfall parameter data that has been processed shows that the rainfall in Kototabang in January - October 2020 and 2021 has a high rainfall value. This causes the intensity of rainfall in Kototabang to be categorized as heavy rain. The two accumulations of rainfall in 2020 and 2021 in the Kototabang area are 497.031 mm and 0.602 mm using the Rain Gauge. While the measurement using Optical Rain Gauge rainfall intensity is 0.207 mm and 0.221 mm. This proves that the intensity of rainfall in 2020 is greater than the intensity of rainfall in 2021.

It also conducted a test time of cooking and water absorption index. This research is using experimental method. The sample in this study was fresh breadfruit fettuccine with 60%, 70%, and 80% hanjeli flour substitution which was then tested on 30 untrained panelists. The test results showed that the substitution of hanjeli flour in the manufacture of breadfruit fettuccine only affected the aroma aspect. Based on the results of the Tukey test on the aroma aspect, the formula most favored by consumers and recommended is the substitution of 60% hanjeli flour. In the cooking time and water absorption index tests, it was found that there was no significant effect. However, cooking time affects the water absorption index. This is directly proportional to the water absorption index and the change in dimensions, where the longer the cooking time, the more the pasta will absorb water. Fettuccine breadfruit substituted with hanjeli flour with a percentage of 80% is the sample with the best water absorption index value in the al dente cooking process.
