  • Camels Production in Sudan: Impact on the Food Security and Circumstances

Abstract

In Sudan given climate is nearly extremes and food insecurity in most regions of the country, the food availability is a crucial component of household food security status. Camel production play an important role in the livelihood of people in dry and semi dry zones, however camel pastoralist challenged by serious production constraints e.g. the lack of marketing facilities, improper infrastructure, impact of liberalization policy on prices and civil war. The general objective of this study was to assess the role of camel production on food security in the Butana State in weastern Sudan. Precisely the objectives aim to identify the main factors that may be responsible for food insecurity among camel pastoralist. The study is heavily depending on primary data collected during the season 2013/2014. Statistical tools of data analysis are implemented focusing on descriptive, food security status and logistic binary regression methods. The study results are showed that most of the surveyed camel pastoralists are illiterate and landless. The study reveals that lowe percentages of sampled households in the study area are faced to food security. According to the results, the camels production are significantly improves food security. There are positive correlation between education level, food availability and food access. Moreover, food utilization is significant affected by family size and number of males in the households. In addition, it is substantial affected by milk production and camel selling in the region. The major constraints of the camel production were the camel diseases such as trypanosomiasis and mastitis. The food insecurity reducing by the age of the household-headed.

  • Assessment of cytological atypia, AgNOR and nuclear area in epithelial cells of normal oral mucosa exposed to toombak and smoking

Abstract

The purpose of this study was to assess cellular proliferative activity of clinically healthy oral mucosal epithelial cells of toombak dippers and smokers by means of AgNOR counts and nuclear areas via nuclear morphometry. Smears were collected from normal-appearing mouth floor mucosa and tongue of 75 toombak dippers, 75 smokers and 50 non-tobacco users between the ages of 20 and 70 with a mean age of 36 years. AgNORs were counted in the first 50 well-fixed, nucleated squamous cells and nuclear areas were calculated via microscopic stage micrometer. Cytological atypia was ascertained in 6 tobacco users and could not be ascertained in non-tobacco users. Statistically mean AgNOR numbers per nucleus in the non-tobacco users (2.45±0.30) was lower than the toombak dippers (3.081±0.39, p<0.004), and the smokers (2.715±0.39, p<0.02), and mean nuclear areas of epithelial cells of toombak dippers (6.081±0.39, p<0.009) and smokers (5.68±10.08, p<0.01) was also significantly higher than non-smokers (5.39±9.4). The mean number of nuclei having more than 3 AgNORs was 28%, 19% and 7% in toombak dippers, smokers and non-tobacco users, respectively. These findings support the view that toombak dipping and smoking are severe risk factors for oral mucosal proliferative lesions and exfoliative cytology is valid for screening of oral mucosal lesions.

Key words: toombak, smoking, oral mucosa, AgNOR, nuclear area.

  • Rheological and quality characteristics of composite gluten-free dough and biscuits supplemented with fermented and unfermented Agaricus bisporus polysaccharide flour

In this study, functional, rheological and physicochemical characteristics were carried out for composite gluten-free (CGF) flours, dough and biscuits, respectively fortified with fermented and unfermented Agaricus bisporus polysaccharide (FABP and UABP) flours. Addition of both FABP flour and UABP flour improved functional properties, while addition of FABP flour decreased viscosity property. Incorporation of both polysaccharide flours in CGF biscuit dough revealed a significant increase in rheological moduli (G׳ and G’’) and a decrease in tan (δ). Supplementation of UABP flour increased thickness, whereas supplementation of FABP flour increased diameter and spread ratio. All CGF biscuit formulations exhibited lower fracture strength and hardness compared to the control. Furthermore, both UABP flour and FABP flour formulation (F3) contained the highest nutrients in terms of protein, dietary fibers, amino acids and minerals among the CGF biscuit formulations

  • A low-cost fuel selling machines using RFID and IoT technology

Technological development is growing rapidly
worldwide, so many machines, factories, and even homes use
these technologies .The target of this paper is to avoid Cars
congestion and long waiting in the queue of fuel pumps,
excessive employment. The commission is not available
financially. And lack of reliability in the sales system. The
automatic implementation of the technological systems is very
useful for the security and confidentiality of the mechanisms
and factories in particular with respect to access to devices and
the user authorized to carry out specific operations. In this
work, an automatic fuel selling machine system is designed
using the Radio Frequency Identification RFID device and The
Internet of Things technology. The designed system is
providing fast filling of fuel, ease in financial transactions, and
more secure by checking the rights of access to the device using
the RFID card read by the reader. In addition, the system
allows the possibility of monitoring the access to the fuel
station and offer a special graphical user interface to the
service provider.
