Tanning system was conducted in industrial research consultancies center, Sudan. Mechanical and physio-chemical analyses of the leather were executed using SLTC. Mechanical properties of the produced leather were compared with traditional tanned leather and the strengths, of tensile, one edge tear and two edges tear, of semi chrome tanned leather were: (200 kg/cm2, 52 and 100 kg/cm) respectively where the distension and strength of grain was (10 mm) and the thermal stability (100°C). The experimental explain that the blending ‘Garad-Neem’ significantly enhanced the quality of tannins powder and tanned leather.

Position and Extent of the Elongation Zone in the Root Tip of the Broad Beanvicia Faba L
BIOLOGIA PLANTARUM (PRAHA) 8 (6) : 427--430, 1966 Position and Extent of the Elongation Zone in the Root Tip of the Broad Bean Vicia faba L. ALENA ADA_MKOVX and KAREL BENE~ Institute of Experimental Botany, Czechoslovak Academy of Sciences, Praha* Received November 9, 1965 Abstract. It was found by measuring the length of the cortex cells of the root tips of the broad bean Vieia faba L. that the beginning of the elongation zone lies at about 1--2 ram from the initials and its end at about 7--8 mm fl'om the initials. Shrinkage of the object during micro- technical treatment was negligible. The autonomy of the individual tissues of the root tip was taken into account. Introduetion Biochemical investigation of anatomically strictly defined parts of the root tip has become a common method for studying cell growth and tissue differ- antiation (BRow~r and BROADBENT 1951, I~OBINSO~r and BROW~r 1952). The results of the present work should serve as an anatomical basis for a series of papers dealing with the biochemical investigation of growth and differenti- ation processes in the bean root tip. The beginning and end of the elongation zone should be established here. Material and Methods Seeds of the broad bean Vicia faba L. cultivar Chlumeck~ were sterilized for 4 min with 70 % ethanol, washed for 8 h in running tap water and left to swell for 12 h in distilled water at 26 ~ C. The seeds were then placed onto wet paper wool laid on PVC plates with openings so that they lay above the opening. -

We are moving forward with the Aboriginal Education department goals of improving literacy and numeracy through land based learning, providing opportunities for students to share their individual stories, and working toward Truth before Reconciliation, deepening relationships with the traditional territories our school district operates on and the Metis Nation. Created by the Aboriginal Education staff last year, we looked at the fire within and our daily work with students, families, and communities. This is such an exciting time in education, in history, and in our personal stories – as we all witness Indigenous ways of knowing blossom! What does blossoming look like in SD8? Whether that is through student pride in sharing a pow wow dance, a personal regalia story, a drum song, a new graphic design, entrance to College, or graduating with dignity and identity, or connecting to community teachings, or finding a sense of belonging in school, the faces of SD8 Aboriginal students, their learning, their successes and their dreams and goals are diverse. Yet, we see the goals of our District Enhancement Agreement flourishing through a variety of student successes, as individual as each of those bright faces. The District Aboriginal Education Advisory Committee and Elders’ Council, for the first time this year, welcomed guests from both the Syilx, Okanagan Nation Alliance, as well as guests from Enderby, from the Secwepemc Nation. -

Phase-Out of Chromium (III) in Leather Tanning
Phase-out of chromium (III) in leather tanning This case study aims to illustrate an alternative process. It is based on publicly available information on company's experience as well as on substance hazards, alternatives to the hazardous substance and regulatory information. The case study is neither complete nor comprehensive in illustrating all substitution options of a substance but rather exemplary. 1. Case description The conversion of hides or skin into leather involves a tanning process. In g e n e ra l , d e p e n d i n g u p o n the end application of leather, two tanning methods are used: vegetable tanning or chrome tanning. 80 – 90 % of tanneries around the world today use salts of trivalent chromium for tanning. The main chromium compound used for leather tanning is chromium (III) hydroxide sulphate, Cr(OH)SO4 (CAS No. 12336-95-7; EC No. 235-595-8). Chromium is associated with several negative effects for the environment and human health. The main hazards related to chromium (III) is that it can be oxidised to chromium (VI), e.g. at very low pH values when oxygen is present. Cr (VI) is a suspected carcinogen and causes skin sensitisation. Since chromium (III) can transform into chromium (VI), its use in articles that may be in direct skin contact, should be avoided. 1.1. Hazards of chromium (VI) Chromium (VI) causes an allergic contact dermatitis and sensitisation at very low concentrations. The risk assessment made by Denmark (also proposing a restriction to market certain articles of leather coming into direct contact with the skin) demonstrates that chromium (VI) present in shoes and other leather articles poses risks for consumers. -
Mangrove Arboretum
Mangrove arboretum The arboretum in Bac Lieu is a collection of mangrove species from the south of Viet Nam. The arboretum is a show case of species richness and thus contribute to the preservation and research of mangrove forests. Furthermore, it serves eco-tourism and is considered as learning resource on mangroves in the Mekong area for students and practitioners. Worldwide, about 73 different species are accounted as ‘true mangroves’. In a total, there are 39 true mangroves described for Vietnam and at least 27 can be found in the South of Vietnam. There are not many stands of natural old mangroves remaining in the Mekong Delta, most of the forest is reforested. For reforestation efforts in the past only few species were selected and the more important it is for the future to diversify the planting schemes since every species is the result of a long evolutionary adaptation process and thus much more resilient if planted at the right place with certain environmental conditions. Mangroves store about 78,8 tons of carbon per hectare and provide high ecological services such as being nursery and foraging space for numerous coastal shrimp, crab and fish species important to local fisheries and aquaculture.

Horne Tanning of Leather By M. K. Thornton, Leather Specialist One of the oldest arts known to man, the tanning of leather, has become almost a lost art to farmers and ranchers. Yet it is a fairly easy process if care is taken. ' There are many methods of tanning, and no one of them rnay be called best. The methods described here are among the easiest and produce satisfactory results. No attempt is made to give details to suit every kind of weather. The ideal temperature is from 70 to 75 degrees F"ahrenheit. In no case should the hides be permitted to freeze. The warmer the weather the more quickly hides spoil, and as - a result there is greater likelihood of getting weak or tender leather. The hides to be tanned may be fresh, green salt, dry salt, or flint. A fresh hide is one which has been taken from the animal and allowed to cool. A green salt hide is one which has been well salted shortly after being removed from the animal, folded and placed in a cool place until the salt has penetrated well, and then stored until ready for use. -
