Abstract
Compared with traditional laboratory gas chromatograph, portable gas chromatograph has the advantages of fast detection, low power consumption, lost cost and possible applications out of Lab. In this paper, aiming at replacing the traditional column thermostat, we presented a 4 cm · 4 cm micro gas chromatography (μGC) chip with a thickness of about 1 mm and a column length of 3 m integrating the Pt heating wire and snake-shaped temperature sensor, which greatly reduces the power consumption and volume of the portable gas chromatograph without losing the separation performance of the μGC chip. The integrated μGC chip was fabricated by micro electro mechanical systems (MEMS) process and its temperature was controlled in closed-loop by fuzzy proportion integration differentiation (PID) algorithm. Experimental results indicate the temperature control accuracy under constant temperature can be up to ±0.05 °C. When heating to 180 °C, the power consumption is less than 15 W. The chip has good separation properties when it was used to detect 4 kinds of benzenes, 8 kinds of alcohol mixtures and 10 kinds of alkane mixtures.

Abstract
Quantification of the contribution of atmospheric circulation to damaging extreme weather and climate events and the attribution of extreme events in the context of climate change has been gaining worldwide interest. Attribution analysis helps us to better understand the risks associated with the effects of climate change on extreme events. However, the contribution of atmospheric circulation, as well as the influence of climate change, to the record-breaking precipitation event in the middle and lower reaches of the Yangtze River and the concurrent record-breaking hot event in South China during the Meiyu period (June–July) in 2020 are still unclear. In this study, we use flow analogues to estimate how much the atmospheric circulation can explain these two extreme events and the influence of climate change. The results show that the atmospheric circulation explains 70.73% and 43.61% of the extreme precipitation event and the concurrent hot event, respectively. Compared with past climate, the occurrence risk of an event reaching or exceeding the 2020 Meiyu amount under similar atmospheric circulation conditions increased by 5.1 times under the present climate, 80% of which can be attributed to climate change. In addition, hot events similar to the 2020 event cannot occur under past climate, while those reaching or exceeding a one standard deviation threshold increased from 0.58% under past climate conditions to 68.83% under the present climate, 99% of which can be attributed to climate change. These results are beneficial for the understanding and prediction of extreme events in the context of climate change in this region.

Abstract
The strategy for improving the productivity of fruit and vegetables in Indonesia can be done through modification of the existing cultivation system by adding certain component of healthy practice farming. One of the approaches for achieving that aim is through the usage of endophytes in cultivation system. The identified mechanisms of endophytic microbes are that the stimulant produced by them is able to suppress diseases and pests that pose a significant threat for plants. Moreover, endophytic microbes are also capable of producing antimicrobial compounds and bio stimulating compounds such as phytohormones and proteins. The purpose of this study was to determine the ability of endophytic bacteria isolates that were taken from collection of Indonesian Citrus and Subtropic Fruits Research Institute in producing IAA hormone, phosphate solvent and nitrogen fixing. The research consisted of several stages; testing for Free Nitrogen Binding Bacteria; Phosphate Solubilizing Bacteria and in Producing IAA. The results showed the three endophytic bacterial isolates isolated from different citrus varieties had the ability to fix free nitrogen. G.28-isolates and G.35_isolates had identical ability to dissolve phosphate, while G.31-isolates could not dissolve phosphate. The most effective time to produce IAA is the fourth day of incubation. G.35-isolates was the bacterial isolate that had the highest IAA production.

Published: March 2021

Abstract
As a result of the analysis of the main technical and economic indicators of the introduction of new test equipment for the determination of toxic elements in food in the laboratory center, it was found that the replacement of the photoelectric concentration colorimeter “KFK-2MP” with the analyzer “Pan-arsenic” when analyzing samples of food products and food raw materials for the content arsenic will be effective. Replacement of the outdated and decommissioned model of the atomic absorption spectrometer “Kvant-AFA” for the atomic absorption spectrometer “Kvant-2AT” in the analysis of samples of food and food raw materials for lead and cadmium content will be effective. The option of replacing the Kvant-AFA spectrometer with a voltammetric analyzer “TA-4” when analyzing samples of food products and food raw materials for lead and cadmium content will be effective if the performance of the new equipment meets the laboratory’s needs in the number of studies, and the purchase of atomic -absorption spectrometer will not be advisable due to the absence of the need for its performance for the implementation of measurements and insufficient solvency of the laboratory. The introduction of the PLP-01M microwave laboratory system introduces a limitation on the number of studies per year, which reduces the capabilities of the measuring device, in cases both for the simultaneously introduced spectrometer “Kvant-2AT” and for the already used “Kvant-AFA”. The introduction of the PLP-01M system will be beneficial if the performance of the new equipment meets the laboratory’s needs in the number of studies.

Published: March 2021

Abstract
Blackcurrant is the most attractive source of ascorbic acid compared to other berries and fruits. The seasonality of berry production makes think about ways to preserve them. One of the most environmentally friendly ways is to freeze berries. However, in terms of biochemical value, frozen berries differ from fresh ones. After defrosting, a decrease in the content of ascorbic acid, soluble solids and titratable acids is observed in the berries. Analysis of currant berries during the harvest period for the content of heavy metals makes it possible to evaluate the quality of the finished product, used fresh and as raw material for further processing. Preservation of currant berries by freezing led to a change in the content of heavy metals: an increase in manganese, copper, iron and a decrease in nickel, zinc, cadmium, cobalt.
