Mineralogical, geochemical, and textural analyses of the white sandstones （Abu Thora Fm.） of Carboniferous in the Abu Rodeiyim region show that they are fluviomarine, well-sorted, highpurity, and high-grade silica SiO2 （average 99.56%）. The results indicate that by simple treatment, the white sandstones can reach a high degree of purity, suitable for different industrial purposes （e.g. manufacture of silicon photovoltaic, crystal, and TV screens, art, and domestic and optical glass）.

The past few years have witnessed significant progress in emerging disease detection techniques foraccurately and rapidly tracking rice diseases and predicting potential solutions. In this review we focuson image processing techniques using machine learning (ML) and deep learning (DL) models related tomulti-scale rice diseases. Furthermore, we summarize applications of different detection techniques,including genomic, physiological, and biochemical approaches. In addition, we also present the state-ofthe-art in contemporary optical sensing applications of pathogen–plant interaction phenotypes. Thisreview serves as a valuable resource for researchers seeking effective solutions to address the challenges of high-throughput data and model recognition for early detection of issues affecting rice cropsthrough ML and DL models.

植物病原菌不断危害农业生产和粮食安全。因此,病害发展早期的动态表征对病变监测和显症前诊断至关重要。高光谱成像(HSI)在跟踪病害初始侵染部位的动态进程以进行显症前诊断方面具有巨大潜力。然而,目前尚无相关文献提取出早期感染阶段活体叶片病变组织的指纹光谱特征(FSS),也没有探究HSI的检测机制。其中FSS是指能够表征特定植物病害的独特、有代表性的光谱特征。在本研究中,基于时序HSI数据分析,提取了接种Bipolaris sorokiniana的大麦叶片的FSS,以表征叶斑病症状发展,实现显症前诊断。还研究了叶斑病早期发展阶段叶片的光谱和生化响应。本文所提取的全波段FSS能够捕捉病变发展过程中褪绿组织和坏死组织的独特特征,从而原位可视化植物-病原菌像素级的早期互作动态进程。进一步,实现了接种后24 h叶斑病的显症前诊断,比传统的聚合酶链反应(PCR)测定或生化测定提前了12 h。为了揭示HSI显症前诊断的机制,还建立了叶片的平均光谱响应与其生化指标(叶绿素、类胡萝卜素、丙二醛、抗坏血酸和还原型谷胱甘肽)之间的定量关系,回归模型在预测集上的Rp2均高于0.84。总体结果表明,HSI反映了活体植物特性的变化,所提取的FSS可成功跟踪叶斑病发生发展的时空动态进程,实现显症前诊断。在其他植物病害上的试验表明,该方法在植物病害早期控制方面具有较大的推广潜力。

Objectives: To define optimum food and nutrient profiling in gender-specific and age group-specific variant regression models. Setting: 481 subjects of both sexes (18.4 years old) from Giza urban were set. Design: Dietary assessment used the 24-h dietary recall data to calculate the estimated energy and (24) nutrients eaten by each individual. Four indices—food variety diversity score, healthy eating index (HEI), mean probability of nutrients adequacy (MPA) and nutrient rich food (NRF9.3) index score were used for assessing the profiling of the diet. Results: A total of 163 individual food items were consumed by the participants within the 24-h dietary recall with an average daily intake of (6.6) different food varieties. Grains were the top contributors of energy and 10 macro and micro nutrients followed by the meat group. Based on the MPA data, the mean acceptable intake (AI) of dietary calcium (32.9%) and vitamin C (30%) were limiting in the diet. The diet profiling consumed by the teenagers aged 14.8 years was inferior compared to that consumed by subjects aging 23.9 years. Linear regression analyses were conducted between the 4 indices as the dependent variable and all possible combinations of 16 nutrients of interest as independent variables. NRF9.3 was the optimum nutrient index and correlated negatively with markers of abdominal obesity. Conclusion: Implementation of nutrition intervention program was directed to youths to include age appropriate good healthy foods to decrease the risk of nutrient deficiencies.
