The study aims at estimating internal rate of return for the cultivation of date palms project in the new lands to encourage small investors and young graduates, to adopt projects of sustainable agricultural development under the assumption of change revenues and invested costs of the project. Also, explaining some productivity and economic indicators to produce dates in Egypt. The study showed that palm area, number of fruitful palms, palm productivity and the total production of dates annually increase at significant rates during the period of 1996 - 2010. The most important regions producing dates are Behera, Ismailia, 6 October, Aswan, New Valley, Matrouh and Noubaria zone. The most important cultivated varieties are Zaghloul, Samani, Meghal and Siwei. The study indicated that internal rate of return in the new lands as in Northern Sinai, Matrouh and the New Valley reached 28%. It was observed that decreasing total revenue up to 25% with increasing investment costs up to 25%, the internal rate of return is not less than 18%. So, cultivation of date palms is economically a profitable project. Thus, this project contributes to the horizontal agricultural expansion, reducing desertification, encourages some industries related to palm cultivation, creates new jobs, increases date export opportunities to overseas markets and increases agricultural income. Also, profits gained by young graduates are sufficient to pay annual premiums of received loans in addition to the interest of these loans, so that the left return is enough for their livelihood.

The effect of the UV-C treatment on the physico-chemical characteristics, pectin methylesterase activity (PME) as well as microbial quality of orange juice, compared to fresh juice, was studied. The juice samples were UV-C (254 nm) irradiated for different exposure times (15, 30, 45 and 60 min) and stored at 4 ± 1 °C for 30 days. UV-C treatment didn't significantly (p ≤ 0.05) affect pH values, titratable acidity, TSS (%), ascorbic acid content and PME activity in both fresh and stored samples. Increasing the exposure time from 5 to 60 min. showed no significant effect (p ≤ 0.05) on L* and a* values for both the fresh and the stored samples. On the contrary, negative relationship was observed between UV-C exposure time and b* values. Total bacterial counts were significantly (p ≤ 0.05) reduced from 2.69 to 0.93 log10 CFU/mL when the exposure time was increased from 0 to 60 min. The UV-C treatment showed similar trend on yeast and mold counts but to a lesser extend due to their resistance to UV. The sensory characteristics, i.e. odour, colour, taste, consistency and overall acceptability didn't change (p ≤ 0.05) as a result of UV-C treatment at any tested exposure times.

Abstract Malnutrition is the major cause of mortality and morbidity globally with undernutrition contributing about 45% of all deaths of under five children. Besides the direct effects of protracted conflicts, the macroeconomic crisis that has greatly increased the national inflation rate hence devastating the purchasing power, the COVID-19 outbreak, flooding, and the Desert Locusts have contributed to a food security emergency. Besides being among the most under resourced states, South Kordofan has experienced years of conflict resulting in displacement of people and extensive infrastructure destruction with high rates of malnutrition. The state currently has 230 health facilities and out of these, only 140 are providing outpatient therapeutic programme centres with 28.6% (40) of these being operated by the state ministry of health and the rest by the international non-governmental organizations. Limited resources leading to donor dependence, limited accessibility due to insecurity and floods, poor referral system and gaps in continuity of care, lack of operational and implementation research data and limited integration of management of malnutrition in other health services have negatively affected effective implementation. Ensuring effective and efficient community based management of acute malnutrition, implementation needs action beyond the health sector with a multi-sectoral and integration approach. Federal and state development frameworks should ensure a comprehensive multi-sectoral nutrition policy with strong political commitment and allocation of adequate resources to ensure integrated and quality implementation.

Language has a significant contribution to the exchange of knowledge. Scholars examine different uses of language to find out its effect and role in several domains of society such as media, criticisms, politics, and related fields. Discourse analysis is connected with the use of both spoken and written language. It supports in analyzing how users say things, their effect on the audience, and how it influences society, or the way society affects communication. This mixed-mode research aims to provide a systemic analysis on how oppressed masses use signs and symbols through different social media platforms such as Facebook, WhatsApp, Twitter, and Instagram to encourage teachers to protest and achieve parents’ support to prevent their children from going to schools, in a Jordanian context. The sample of the study consisted of 189-selected posters/signs and symbols using a convenient sampling technique. The selected Arabic posters were translated into the English language. The researcher used the analytical instrument adopted from Van Dijk's (2005) framework of political discourse analysis. The corpus was analyzed contextually. The findings of the study showed that in the reaction to meeting demeaning and dismissive discourses, schoolteachers reacted as inheritors of cultural legacies, meaningful resources, context specialists, professionals, and moral authority figures. In addition, the results indicated a strong link between political discourse analysis and the use of sign language that reflects the social practices of protesters and oppressed masses. To conclude, this study is an add-value to both local and body of knowledge locally, regionally, and internationally concerning theory and practice in which previous experience shows every possible influence to preserve public sustenance, show criticism, and express demands as teachers’ signs and symbols in different provinces in Jordan worked effectively in a civilized manner.

A new approach to the analysis of thermoluminescence (TL) glow-curves of LiF:Mg, Ti (TLD-600) following alpha particles irradiation has been presented using general expressions derived from the one-trap-one recombination (OTOR)-level model. It has been found that the results of the deconvolution in the case of using these expressions are different from the case of using the other TL expressions, especially for the high-temperature region. The advantage of using the OTOR expressions is that, unlike the usual analysis, a good fit and reasonable kinetic parameter values could be obtained with a lower number of deconvoluted peaks. The kinetic parameters and the dosimetric properties of each peak have been investigated over different absorbed doses and new findings have been found. Improvement of the accuracy and the precision of the dose measurements at low-dose levels has been achieved using the glow-curve deconvolution algorithm. In addition, theoretical interpretations of some observed behaviors have been presented using the interactive multiple trap system model. [ABSTRACT FROM AUTHOR]

A high pure germanium detector-based gamma-ray spectroscopy low-background counting system was used to determine the levels of natural radioactivity from beach sand samples on the Egyptian coast along the Mediterranean and Red Seas. The activity concentrations of 226Ra, 232Th and 40K were found to lie in the range of 30±11 to 60±14 Bq kg−1 with a mean of 39±15 Bq kg−1, 12±3 to 30±14 Bq kg−1 with a mean of 21±13 Bq kg−1 and 392±22 to 413±22 Bq kg−1 with a mean of 402±23 Bq kg−1, respectively. Radiation hazard indices and annual effective doses were evaluated and compared with the international data. The results indicate that the values obtained fall below the internationally accepted maximum limits and do not pose any significant radiation hazard to individuals in the study area. From these results, a radiological baseline map of Egyptian beaches can be drawn and used as reference information to assess any future alterations in the radioactivity of beach sands due to any changes in the sea sediments.

The smoking habits of 50 proved cases of chronic bronchitis were studied. Bronchoscopy was done and a bronchial biopsy was taken for histological examination. Bronchial lavage was obtained under sterile conditions for bacteriological studies. The degree of bronchial mucous gland hypertrophy was determined, and the presence or absence of infection, as shown by the presence of potential pathogens in the bronchial lavage, was noted. We think that tobacco smoking and its resulting irritation to the bronchi is the most important underlying cause of bronchial mucous gland hypertrophy because there is: (1) a significantly higher incidence of mucous gland hypertrophy in smokers than in non-smokers among the 50 chronic bronchitics studied; (2) a significantly higher accumulated lifetime tobacco consumption in patients exhibiting mucous gland hypertrophy than in those without hypertrophy of the bronchial mucous glands; (3) a significant association and correlation between the degree of mucous gland hypertrophy and the intensity of smoking; and (4) no difference in the comparative frequency of occurrence of bronchial mucous gland hypertrophy in subjects with and without demonstrable infection, as shown by the presence of potential pathogens in the bronchial lavage. We could not deny that infection might be having an initiating or potentiating effect. [ABSTRACT FROM PUBLISHER]
