Geology, Radioactivity and Uranium Potentialities of Some Pegmatite Bodies at Wadi Al Shayilah and West of Gabal Kherm El Asmar Area, North Eastern Desert, Egypt

Hossam A. Khamis

ABSTRACT: The area around Gabal (G.) Kherm El Asmar is occupied by metavolcanics, Dokhan volcanics as well as different types of younger granite pertaining to the Syenogranites and alkali feldspar granites. These rock types are intruded and traversed by numerous types of dyke swarms and dissected by many fault trends. The metavolcanics are mainly represented mainly by metabasalt, metabasaltic andesite and very rare metamorphosed pyroclastics. The Dokhan volcanics are represented by andesite, dacite as well as acidic and intermediate tuffs and agglomerates. Syenogranites in the area represents a part of G. Urf El Eeir which is coarse grained porphyritic pink granites while alkali feldspar granites represent part of G. Al Shayilah medium grained equigranular reddish pink granite cut and dissected by dyke swarms and traversed by different trends of shear zones. Late magmatic pneumatolytic and hydrothermal stages which products pegmatites, aplites and silica veins are frequently seen in both types of granites but are very spectacular in alkali feldspar granites where large pegmatites veins and pockets are spread in many parts of the intrusion. These pegmatites play a major role in the localization and potentialities of uranium in this sector of younger granites. Most of the radioactive anomalies are connected to the alkali feldspar granites where U and Th have a reasonable concentrated. In the zoned pegmatites, the uranium concentration is seen to be relatively high and reaches up to 250 ppm while the Th recorded 75 ppm. The relatively high uranium concentration provides the opportunities for the crystallization of uranium minerals in these pegmatites where both Uranophane and Kasolite are recorded in notable amounts giving the high U potentialities for these pegmatites.

Hassan I. A. Ahmed and Yasser M. M. Osman

ABSTRACT: This study was conducted to investigate the effects of garlic cultivars (Balady, Chinese, and Sids-40) and some edible coating treatments (T1: Carrageenan + potassium sorbate, T2: Chitosan + potassium sorbate, T3: Chitosan +Carrageenan + potassium sorbate and control), and different cold storage periods on the yield, bulb quality, and preservation period of under consideration cultivars of garlic. The results showed that the Sids-40 cultivar was the highest yield, bulb weight, and bulb diameter
after curing. Also, Chinese and Sids-40 cultivars achieved the highest values of cloves weight/ bulb. While Balady cultivar was recorded the highest values of cloves number. Balady cultivar was scored lower values of sprouting and decay percentages than Chinese and Sids-40 cultivars. The chemical analysis of different garlic cultivars, edible coating treatments, and different cold storage periods were studied. The obtained results were indicated that the Chinese cultivar had the highest moisture content followed by the Sids-40 cultivar. While the lowest moisture content was recorded by Balady cultivar, meanwhile, it was recorded the highest amount of carbohydrate, fat, and ash, respectively. On the other hand, Sids-40 had the highest value of protein content. According to the results of garlic cultivars, combined with the effects of different cold storage periods and edible coating treatmentsmaintained quality attributes and shelf life of peeled garlic cloves compared with the control sample. Based on our results, some of the functional compounds of garlic were also influenced by storage period, garlic cultivars, and edible coating treatments and they had a positive effect on the keeping of all physicochemical and microbial quality parameters for a longer storage period reached to 270 days. It was noticed that treatment No. (3) was the most effective treatment until the end of cold storage periods for all garlic cultivars especially, Balady cultivar. Moreover, results suggested that the treatment (Chitosan + Carrageenan in addition to potassium sorbate) at cold storage conditions could be a promising treatment for extending the storage period and maintaining postharvest quality of peeled garlic cloves especially, for Balady and Sids-40 cultivars.

Long Term Soft Denture Liners; Current Status, Clinical Performance and Limitations

Mohamed H. Abdelnabi and Amal A. Swelem

ABSTRACT: Long term soft liners are used to alleviate discomfort and tissue damage associated with complete denture intolerance due to functional factors. This article reviews long term soft liners as regards the basic classification and both clinical and patient centered treatment outcomes. Each of the authors independently conducted a manual and electronic search of the English literature up till December 2020. Initially the titles were extracted based on predetermined inclusion and exclusion criteria. Abstracts of the selected titles that both authors agreed upon were then screened. The last stage was the extraction of relevant data and including it under headings in a narrative review of literature format. It was concluded that, in properly selected cases, long term soft liners could be considered an affordable solution that significantly improve clinical and patient centered treatment outcomes. Clinical outcomes included maximum occlusal forces, effect on mandibular movements during the chewing cycle, masticatory performance, effect on electromyographic recordings, in addition to fungal overgrowth and its consequences on denture hygiene and related mucosal inflammation. Patient centered parameters included patient self-assessment, satisfaction, preference and impact on Oral Health Related Quality of Life. Proper selection of the type of soft liner plays a crucial role in reaching a successful outcome. Major concerns with long term soft liners include loss of resiliency, fungal overgrowth, debonding and hygiene maintenance. This review also discussed the limitations of the available studies. Clinical studies recruited only complete denture patients with good prognosis and not the compromised cases that actually need management with soft liners the most. It was thus suggested that the functionality of this category of complete denture wearers could be an area of focus for upcoming randomized controlled clinical studies.

Fatma M. I. Shahin and Zahrat El-Ola M. Mohamed

ABSTRACT: Pigmented corn contains several bioactive phytonutrients that possess antioxidant, antitumor and anti-inflammatory properties. In this study, potential beneficial components of five pigmented corn hybrids: white (132), red (R370and Rsc-1), and yellow (178 and 180) were investigated. In addition, wheat flour was substituted by corn flour hybrids at different levels. 0, 10, 20 and 30% (w/w), respectively to prepare instant fried noodles. Color, cooking properties and sensory characteristics of instant fried noodle were evaluated. The values of protein and total phenols were observed in R370 hybrid, meanwhile, yellow178 had the highest oil, P, Fe and Zn content among other hybrids. Besides, Rsc-1 had high content of anthocyanin and K. Yellow corn hybrids had a high content of carotenoids. However, high antioxidant activity was observed in red corn hybrids. With respect to the sensory characteristics points of view, noodles prepared by substituted wheat flour with yellow 180 flour at different levels enhanced noodles color in relative to other noodle samples. There were no significant differences among all noodle samples in odor score. Regarding to overall acceptability and total quality scores, there were no significant differences among control and 10 and 20%substitution levels samples of yellow 178 and 180.In general substitution with 10% of white and red hybrids was accepted.The cooking noodle weight was increased with increasing the addition of different corn hybrids until 30%. A slight decrease was observed in protein content in substituted noodles with corn flour. Meanwhile, ash and fiber content was increased in noodles with increasing corn flour levels. Therefore, the production of noodles using corn flour-wheat composite flour is recommended.
