In this study, a generic intelligent wireless sensing platform with the IoT and wireless transmission technology is established for greenhouse monitoring, which is capable of greenhouse data collection and analysis. The data analyzed by a cloud server would provide important information regarding the efficiency of greenhouse management and cultivation methods. To monitor greenhouse related parameters, an embedded board is placed in a greenhouse as the gateway. Monitoring data and images collected by sensors deployed in the greenhouse are transmitted to the embedded board via an Ethernet or wireless transmission module. The data are eventually sent to a database by wireless AP. The AP connects to the internet by using a 4G USB dongle, which can provide sufficient data transmission speed for real-time data transmission. In wireless hotspots and areas with Wi-Fi, not only can images be transmitted to the cloud, but also can the mobile APP be used to perform remote monitoring, so experimental observations are no longer affected by geographical impacts. Moreover, to ensure the preservation of images and numeric data, the gateway carries a high durability secure digital (SD) memory card to store images and data; if the network encounters some problems, such as unable to connect and a lack of network traffic, the data can be stored in the SD card. Thus, the proposed platform is able to perform heavy information transmission duties and support performing all wireless monitoring tasks. In addition, the analyzed data can be used by agricultural personnel to provide critical cultivation suggestions.

Cold water paddy field soils are relatively unproductive, but can be ameliorated by supplementing with inorganic fertilizer from animal waste-based composts. The yield of two rice cultivars was significantly raised by providing either chicken manure or cow dung-based compost. The application of these composts raised the soil pH as well as both the total nitrogen and ammonium nitrogen content, which improved the soil’s fertility and raised its nitrification potential. The composts had a measurable effect on the abundance of nitrogencycling- related soil microbes, as measured by estimating the copy number of various bacterial and archaeal genes using quantitative real-time PCR. The abundance of ammonia oxidizing archaea and bacteria was markedly encouraged by the application of chicken manure-based compost. Supplementation with the composts helped promote the availability of soil nitrogen in the cold water paddy field, thereby improving the soil’s productivity and increasing the yield of the rice crop.

Elevated serum levels of interleukin-10 (IL-10) have been reported in patients with Kawasaki disease (KD). IL-10 reduces the inflammatory actions of macrophages and T cells and it may play a significant role in the regulation of inflammatory vascular damage associated with systemic vasculitis. The aim of this study was to examine whether -592 IL-10 promoter polymorphism is a susceptibility or severity marker of KD in Chinese patients in Taiwan. The study included 105 KD patients and 100 normal controls. Genotype and allelic frequencies for the IL-10 gene polymorphism in both groups were compared. There were no significant between-group differences in the genotype distribution of IL-10 A-592C gene polymorphism (P=0.08). However, the frequency of the -592*A allele was significantly increased in the patients with KD compared with controls (71.9% vs. 61.0%, P=0.019). The odds ratio for developing KD in individuals with IL-10 -592*A allele was 1.64 (95% confidence interval, 1.06-2.52) compared to individuals with the IL-10-592*C allele. No significant difference was observed in the genotype and allelic frequencies for the IL-10 A-592C polymorphism between patients with and without coronary artery lesions. The IL-10-592*A allele may be involved in the development of KD in Taiwanese children.

Hybrid ferromagnet/semiconductor systems have been the focus of considerable attention because of the transport properties of two-dimensional electron systems and their potential applications to magnetic storage and sensing devices. We use the weak localization effect to probe the dephasing mechanism at low temperatures. In our study, the zero-temperature phase-relaxation rate can be enhanced in a hybrid ferromagnet/semiconductor system, which may be due to the inhomogeneous magnetic field emanating from the Ni film. The result may improve understanding of the issue of zero-temperature dephasing in disordered systems.

Increasing the gene copy number has been commonly used to enhance the protein expression level in the yeast Pichia pastoris. However, this method has been shown to be effective up to a certain gene copy number, and a further increase of gene dosage can result in a decrease of expression level. Evidences indicate the gene dosage effect is product-dependent, which needs to be determined when expressing a new protein. Here, we describe a direct detection of the gene dosage effect on protein secretion through expressing the enhanced green fluorescent protein (EGFP) gene under the direction of the α-factor preprosequence in a panel of yeast clones carrying increasing copies of the EGFP gene (from one to six copies). Directly examined under fluorescence microscopy, we found relatively lower levels of EGFP were secreted into the culture medium at one copy and two copies, substantial improvement of secretion appeared at three copies, plateau happened at four and five copies, and an apparent decrease of secretion happened at six copies. The secretion of EGFP being limiting at four and five copies was due to abundant intracellular accumulation of proteins, observed from the fluorescence image of yeast and confirmed by western blotting, which significantly activated the unfolded protein response indicated by the up-regulation of the BiP (the KAR2 gene product) and the protein disulfide isomerase. This study implies that tagging a reporter like GFP to a specific protein would facilitate a direct and rapid determination of the optimal gene copy number for high-yield expression.

The disposal of spent radioactive ion exchange resin generated during the operation of nuclear facilitieshas always been a conundrum. The molten salt oxidation (MSO) for the treatment of mixed resin (MR)shows obvious superiority. In this work, ternary carbonate (Li2CO3-Na2CO3-K2CO3) and MR was usedas the molten salt system and the oxidation target, respectively. The oxidation behavior of MR was analyzedby varying the temperature and oxygen equivalent during the MSO process. By studying the effectof different oxygen equivalents on the oxidation efficiency, the oxygen equivalent of 125% could make theoxidation efficiency of MR reach 99.99% at 800 C. The composition of C, N and S containing exhaust gasproduced through MSO process of MR with temperature were almost consistent with the simulationresults. The exhaust gas was successfully adsorbed by molten carbonate to produce nitrate and sulfurcompounds. The carbonate has good absorption to harmful gases such as SO2, CO, NO, etc. The contentof SO2 from the highest 0.32% to 0, and 71.23% of sulfur in MR was trapped by molten carbonate asthe form of sulfate. This work has important implications for reducing the potential harm of radioactivewaste resin to the environment.
