Internet of Things (IoT) networks present unique cybersecurity challenges due to their distributed and heterogeneous nature. Our study explores the effectiveness of two types of deep learning models, long-term memory neural networks (LSTMs) and deep neural networks (DNNs), for detecting attacks in IoT networks. We evaluated the performance of six hybrid models combining LSTM or DNN feature extractors with classifiers such as random Forest, k-Nearest Neighbors and XGBoost. The LSTM-rF and LSTM-XGBoost models showed lower accuracy variability in the face of different types of attack, indicating greater robustness. The LSTM-rF and LSTM-XGBoost models show variability in results, with accuracies between 58% and 99% for attack types, while LSTM-KNN has higher but more variable accuracies, between 72% and 99%. The DNN-rF and DNN-XGBoost models show lower variability in their results, with accuracies between 59% and 99%, while DNN-KNN has higher but more variable accuracies, between 71% and 99%. LSTM-based models are proving to be more effective for detecting attacks in IoT networks, particularly for sophisticated attacks. However, the final choice of model depends on the constraints of the application, taking into account a trade-off between accuracy and complexity.

剖腹手术后,腹腔内剩余气体之存在为一极普遍之现象,似不足以作系统之研究。但作者用X线透视或摄片作了75例各种腹腔手术后(包括上腹部、下腹部及妇科等手术)气腹之研究,得出结论如下: 1.20%重度气腹(横膈下半月形透明影之高度超过10毫米)。20%中度气腹(半月形透明影之高度在4—10毫米之间)。28%轻度气腹(半月形透明影之高度在3毫米以下)。32%无气腹。 2.如有气腹存在,在手术后第一天,空气最多。在直立位检查时,空气常积聚在横膈下。 3.根据75例病案分析,作者认为手术种类、技术操作、引流、麻醉、年龄等因素与气腹之形成及气腹之多少无多大关系。

Sixteen crossbred buck goats （Kiko x Spanish; BW = 32.8 kg） and wether sheep （Dorset x Suffolk; BW = 39.9 kg） were used to determine the effect of preslaughter diet and feed deprivation time （FDT） on physiological responses and microbial loads on skin and carcasses. Experimental animals were fed either a concentrate （CD） or a hay diet （HD） for 4 d and then deprived of feed for either 12-h or 24-h before slaughter. Blood samples were collected for plasma cortisol and blood metabolite analyses. Longisimus muscle （LM） pH was measured. Skin and carcass swabs were obtained to assess microbial loads. Plasma creatine kinase activity （863.9 and 571.7 ± 95.21 IU） and non-esterified fatty acid concentrations （1,056.1 and 589.8 _＋ 105.01 mEq/L） were different （P 〈 0.05） between sheep and goats. Species and diet treatments had significant effects on the ultimate pH of LM. Pre-holding total coliform （TCC） and aerobic plate counts （APC） of skin were significantly different between species. Goats had lower （P 〈 0.05） TCC （2.1 vs. 3.0 IogTo CFU/cm2） and APC （8.2 vs. 8.5 Iog10 CFU/cm2） counts in the skin compared to sheep. Preslaughter skin E. coil counts and TCC were different （P 〈 0.05） between species. Goats had lower （P 〈 0.05） counts of E. coil （2.2 vs. 2.9 log10 CFU/cm2） and TCC （2.3 vs. 3.0 log10 CFU/cm2） in the skin compared with those in sheep. Diet, species, and FDT had no effect （P 〉 0.05） on E. coli and TCC in carcass swab samples. The APC of carcass swab samples were only affected （P 〈 0.05） by the FDT. The results indicated that preslaughter dietary management had no significant changes on hormone and blood metabolite concentrations and sheep might be more prone for fecal contamination than goats in the holding pens at abattoir.

Journal of Environmental Protection 2021年第1期12卷 1-12页

The protection of aquifers is a major concern for the authorities, especially in areas where there are large agro-industrial exploitations. The objective of this study is to define a new method of aquifer protection based on the characteristics of the structures of aquifers. The intrinsic vulnerability mapping method, PaPrI was used. It is a variant of the PaPrIKa method applied in karstic environment which has been adapted for its application in basement environment. This method uses three factors, including aquifer protection (P), using the soil cover, the unsaturated zone and the thickness of the alteration layer, (r) for the rock type and (I) for infiltration which including slope and drainage density. PAPrI is a method based on the weighting of different factors. The results obtained show 4 classes that evolve from low vulnerability classes (5% of the study area) to high and very high vulnerability classes (58%) and average vulnerability classes (37%). The classes of high and very high vulnerability, which indicate the zones that are very exposed to pollution, are more present in the central-northern part of the study area, with a few appearances towards the south. These zones could be related to topography due to the often very high slopes observed in the area. One of the advantages of this new method lies in the characterization of the alterations that strongly influence the migration of pollutants towards the water tables according to their nature and their thickness.

This work reports the inhibition properties of nicotinamide (NAM) for copper protection during its applications in seawater systems such as water pipelines, shipbuilding, seawater desalination and heat exchange systems. The efficiency of NAM as a copper corrosion inhibitor in simulated seawater (3.5% NaCl solution) was investigated by Tafel extrapolation and linear polarization methods in the temperature range from 20℃ to 50℃. The corrosion parameters and the adsorption isotherms were determined using potentiodynamic polarization techniques. It was found that the inhibition efficiency (η) and the coverage rate (θ) increase up 80% at 25℃ for nicotinamide concentration of 10 mM but decrease as the temperature of the solution increases. Moreover, the obtained thermodynamic parameters using Langmuir model suggested a physical adsorption type. A correlation was found between the corrosion inhibition efficiency and the global theoretical parameters obtained by the functional density method B3LYP/ 6-31 + G (d, p). Local parameters such as condensed Fukui functions [f(r)] and condensed local softness [s(r)] indices have also been determined to obtain a chemical insight into atoms that have a significant tendency toward donation or acceptance of whole or fraction of electrons.

Objective: After the ramadan fasting period, there is an increasing prevalence of diabetes in Cote d’Ivoire, in diabetes care centers. The objective of this study was to assess the consumption of sugary foods during this period and to determine the risks of diabetes in Muslim populations. Methods: Information was collected on the type and amount of sugary foods consumed. Methods for the preparation of these foods have been determined. Intake frequencies and postprandial glycemic responses were studied. The usual statistical methods were used. results: Between 70% and 85% of the “fasters” consume plenty of these sugary foods during this period, with an average added sugar level varying between 10% and 35% and a daily consumption of between 250 cl and 0.5 l. The added sugar leads to hyperglycemia in both healthy subjects and pre diabetics. Conclusion: regular consumption of these sugary foods results in significant hyperglycaemia throughout the month of fasting with a significantly higher blood glucose level in pre diabetic subjects. This makes pre diabetics people more at risk of diabetes among Muslim populations during ramadan fasting.
