  • Future Prospects of Camel Milk under Different Conditions in Sudan: As Source of Organic Food

The present study was designed to highlight the possibility of utilization of camel milk  as organic food. Camels are used traditionally as a source of food, in race and transportation of belongings when pastoral families relocate to new areas and also in fetching water to pastoral homesteads for household utilization. Camel milk is considered as one of the most valuable food sources for nomadic people in arid and semi arid zones and has been consumed; either fresh or fermented; for centuries due to its nutritional values and medicinal properties. In Sudan, most of camels are managed in traditional systems that include: nomadic, transhumance or semi-nomadic system and recently the sedentary or semi-sedentary systems and intensive production systems. A field survey was conducted in two production systems in Sudan. The first was the dominant nomadic systems that depend mainly on the grazing pasture, representing 40% of the total camel milk production in Sudan. The second was the new semi-intensive system that was initiated with the objective of commercialization of camel milk associated with harvesting of camel milk in pre-urban areas of Khartoum. The highest significant percentages of camel milk composition: protein, lactose, total solids, solids non fat, fatty acids and vitamins (A, E and C) levels were recorded for the camel in the traditional nomadic system compared to those from semi-intensive system. This paper recommended utilization of camel milk; especially from traditional systems; as functional and organic food. It also suggests ways to harness the potentials of dromedaries to ensure organic food and environmental sustainability..

  • Prospects of Textile Industry in Sudan (A technical Vision).

Sudan has been known in Africa with many
characteristics regarding its land suitable for
agriculture and the river Nile, making a
continuous irrigation source. However, in
regard of the textile industry, Sudan was
famous in producing different cotton
varieties and grades and the Sudanese cotton
was very famous worldwide with its high
quality. This initiated the earlier beginning
of textile industry which was first started
with some governmental projects followed
by the private sector. The raw material, in
fact, represents a high percentage of the final
product cost. Nowadays, textile industry is
suffering from many problems, facing acute
challenges, and becoming less attractive,
though it can be very attractive if these
constrains can be solved. This article
highlights the current situation of the
industry, the problems facing its
development, and proposing a technical
solution to overcome these constrains. It
also shows the opportunities for investment
in the traditional textile industry and other
related industries.

  • Synthesis and Characterization of Aliphatic–Aromatic Hyperbranched Polyesters with High Organosolubility

Carboxyl-terminated, water soluble, hyperbranched polyesters (HBPET) with aliphatic–aromatic
structure were synthesized at three different monomer mole ratios (A3/B3 = 1 : 1, 2 : 1, 1 : 2, respectively) by melt
polycondensation of aconitic acid and phloroglucinol via A3+ B3 approach. Fourier transform infrared (FTIR)
spectroscopy indicated as that was expected HBPET, which showed excellent solubility in a variety of polar
solvents such as N,N-dimethyl formamide (DMF), N-methyl-2-pyrrolidone (NMP), dimethyl sulfoxide (DMSO),
and tetrahydrofuran (THF). The weight-average molecular weight of HBPET ranged from 7792 to 9214 g mol–1
and their intrinsic viscosity were varied from 0.17 to 0.34 dL g–1. The degree of branching of the HBPET was
estimated to be 0.44–0.49 by 1H and 13C NMR measurement. The thermogravimetric analysis (TGA) measurement
revealed that HBPET was of 10% weight-loss at 340°C in N2.

  • Synthesis and Characterization of A2 +B4 Hyperbranched Polyesters with Hydroxyl end Groups

Hydroxyl-terminated hyperbranched polyesters (HBPET) with aromatic-aliphatic
structure were synthesized by melt polycondensation of isophthalic acid and pentaerythritol via A2+
B4 approach, at three different monomer mole ratios (A2/B4 =1:1, 1.5:1, 2:1, respectively). Fourier
transform infrared (FTIR) spectroscopy indicated that the expected HBPET. The degree of
branching of the HBPET was estimated to be between 0.39–0.45 by 1H-NMR and 13C-NMR
measurement. The thermogravimetric analysis ( TGA ) measurement revealed that HBPET had a
10 % weight-loss at 350°C in N2.
