This paper focuses on a project to work on the digital library of Arab children's culture for sustainable development (DLACSD).

This project claims to link the past, present, and future by creating a platform that can grow to include not only works by adults but by children who inspire adults with their imagination and the joys they bring to the world.

This project addresses in phases the different aspects of the problem of the lack of material for Egyptian/Arab children at different stages in Arabic on the internet (with copyright law in mind). It is time to fill this gap by having a rich repository of stories, plays, games and songs for children in Arabic in a digital library to enrich the life of the child and to inform the world that much that is worthwhile is available in Arabic for parents, teachers, and children to enjoy.

Through reading samples of the works by Abdel-Tawab Youssef (1928–2015) by using the Dublin Core Elements, it will be informative to see how his writings address the United Nations Goals of Sustainable Development way before these Goals were discussed.

Writers for children, librarians, teachers, psychologists, literary critics, illustrators, and parents need a platform that makes material available to promote children’s culture in the Arab world and to introduce the world to what is of value for children in Arabic.

Currently, communication brings the world together and although the social media and the new technology have introduced problems that are serious, to say the least, collaborators on all levels must play an active role in redressing the social wrongs, especially those affecting children.

This ongoing project by members of a team who believe in interdisciplinarity and multidisciplinarity has taken the first step to create and develop (DLACSD).

The Suez Irrigation Canal is the source of drinking water to a large community. Complaints have been raised regarding the odor and unpleasant taste of drinking water. The problems encountered reveled enrichment of the Canal with nutrients, degraded water quality and nuisance caused by algal growth. This paper aims to investigate these claims by evaluating the interaction between water and sediment with ecological indicators.

Bioassessments were used as a primary tool to evaluate the biological conditions and identify the degree of water quality degradation in the Suez Irrigation Canal. The monitoring program integrates biological, chemical, and physical data assessment. Several field surveys were carried out to these areas during the period between March 2003 and February 2005 (over 23 months) for acquiring all possible information about the current situation and to explore the impact of human activities along the canal banks on the canal ecosystem. Seasonal variations of phytoplankton and zooplankton standing crop, species diversity as well as physico‐chemical characteristics of water, sediment, fish and aquatic weeds at the intakes of drinking plants and from the discharge of agricultural and domestic drains into the Canal were investigated.

Preliminary field investigations showed great amounts of discharged wastes at several locations to the canal water creating unique conditions, which vary with changes of volume and properties of the discharged wastes. Rotifer and green algae for example demonstrated seasonal variable response to the ecological variations. Myriophyllum spicatum, Potamageton nodsus and Polygonum Salicfolium were the most common types of recorded weed. The Myriophyllum spicatum is the dominant submerged plant. The canal was characterized by high concentrations of HCO₃^‐ as well as high pH >8.2 which provides a favorable habitat for the growth of Myriophyllum spicatum. The results illustrated the ability of using the aquatic weed as biomarkers for monitoring heavy metals contaminates in the canal. The evidence suggests that there is a degree of selectivity in metals uptake and partitioning within the plant compartments.

The current paper adopts the idea of utilizing multiple organism groups in the bioassessment to effectively detect ecological change when they occur in one of the most important waterways in Egypt. These different organism groups are suited for detection various stressors, providing warnings and detection of stress impacts at different scales. The study presented provides decision makers with important information that can assist them in making objective decisions related to the design of monitoring programs based on scientific research.

This study aims to the synthesis of some novel 4-arylazo-3-hydroxythiophene analogues containing sulphapyridine and sulphathiazole dyestuffs and studying their application in dyeing polyester fabrics and rendering their antibacterial efficacy.

Simultaneous dyeing and antibacterial finishing for polyester fabric using a new antibacterial disperse dye having a modified chemical structure to thiophene dyes were studied. Construction of the thiophene dyes was carried out by diazo-coupling of diazotized sulphonamide-containing heterocyclic rings sulphapyridine and sulphathiazole with ethyl α-phenylthiocarbamoyl-acetoacetate followed by cyclizing the produced 2-arylazo-thioacetanilide with various α-halogenated reagents. All newly synthesized compounds were characterized by elemental analysis and extensive study of their spectral data (IR and ¹H-NMR). The dyeing characteristics of these thiophene dyestuffs were evaluated at optimum conditions. Antibacterial activities of the obtained thiophene dyes were studied against some Gram-positive and Gram-negative bacteria.

The synthesized thiophene-containing sulphonamides dyes were applied on polyester fabric. The modified dyes exhibited a good fastness properties and antibacterial efficacy against some Gram-positive and Gram-negative bacteria. Synthesized dyes showed higher antibacterial potency than the reference standard drug.

Synthesis of these disperse azo dyes for textile dyeing had never been reported previously.

The dyestuffs derived from thiophene are reasonable azo disperse dyestuffs giving good all-round fastness properties on polyester fabrics.

Thiophene dyes are used for dyeing polyester fabrics with brilliant colour and good fastness properties. The presence of sulphonamides moieties increase their fastness properties and elevate their antibacterial properties. Moreover, they can be used as antimicrobial finish due to their bactericidal properties on dyed textiles. This work afforded a new thiophene colorant that can be used in many different uses like polyester packing, thread Surgery, blends and other uses in medical textile.
