Abstract: Background: Termitomyces letestui is an edible mushroom that grows symbiotically with termites. Though this species is present in Cameroon markets, few investigations have been carried to clearly assess its nutrient content. This study aimed to evaluate the effect of collection areas, growth stage and body fruit parts on T. letestui macronutrients and some antioxidants. Materials and Methods: Mushroom samples at different growth stages were collected or purchased from the local markets of three localities: Mbouda, Njingoumbe and Ndop from both the West and North West regions. Their lipid, carbohydrate, vitamin C,.....

Key words: antioxidants, collection areas, fruit body parts, nutrients, stage development, Termitomyces letestui

Abstract: Background: The occurrence of organochlorine pesticides in different compartments of the aquatic ecosystem, even at trace levels and consequently in commercial biological species whichconstitutes man's diet, isn't desirable as they have toxic effects. Fishes are at the highest level of the aquatic food chain and do bio-accumulate these OCP residues, resulting in many health hazards, necessitating the assessment of their risks to man.
Materials and Methods: The organochlorine pesticide (OCPs) residues were measured in water, sediment, fin fish: Ethmalosa fimbriata (Bonga Shad), Cynoglossus browni (Nigerian tongue sole) and shellfish: Callinectes pallidus from Badagry Creek between June and December....

Abstract: Biomimicry is a practical concept, which provides sustainable approaches to solve human problems, by inspirations drawn from nature. It is a practice that learns from and mimics the strategies used by species alive today as well as other features in natures. The goal is to create products, processes, and policies (new ways of living) that are sustainable, solve our greatest design challenges and support all life on earth. Before the wide spread of the concept of biomimicry it has been evident throughout history that practices similar to the concept, such as designs inspired by nature have been in existence. One of such examples is the first air plane model designed by Leonardo da Vinci which was inspired by the flight of birds....

Abstract: Bean seeds flour was enriched with crayfish, dried fish and dried onions. Five samples were generated using the response surface method. Sample A (100%) beans was the control, B (50% beans, 15% crayfish, 25% dried fish, 10% dried onion), C (50% beans, 17% crayfish, 27% dried fish, 5% dried onion), D (51% beans, 20% crayfish, 23% dried fish, 5.3% dried onions) and E (50% beans, 15% crayfish, 28.5% dried fish, 6.4% onions). Steamed beans pudding and bean cakes were prepared with the samples. Sensory attributes of the steamed beans pudding and bean cakes were carried out.......

Abstract: In this study comparisons were done between the physical properties of bag and lining leathers from two different origins- cow and goat. Sample positioning, collection, preparation, conditioning and particular physical tests such as tensile strength, percentage of elongation at break, tearing strength, stitch tearing strength, water vapour permeability, grain crack load, scuff resistance, flexing endurance, bond strength between finish film and leather surface and colour rub fastness were done according to the standard ISO and SATRA methods. In some physical testssignificant differences were found between the bag and lining leathers.In case of bag leather the cow leather showed....

Abstract: Background: Pharmaceuticals are essential for the survival of humans and animals life. Due to economic prosperity and longevity the prescription and use of the pharmaceuticals has increased many folds with the beginning of the present century. Due to misuse and overuse pharmaceuticals are emerging as a major environmental threat. Antibiotics are the most widely used pharmaceuticals. The pharmaceuticals residues or related daughter products are reported in surface water, ground water, soil, milk, plants, vegetables, and fruits posing a threat to humans, animals and ecosystem. As milk, vegetables, and fruits are the sources of vitamins, carbohydrates, essential trace metals, antioxidants these are the key part for survival of the human.
Results:The accumulation of the pharmaceuticals mainly......

Abstract: Sustainability is a "wicked" subject – which most people automatically relate to energy. But it's more. Locally – here specially for the area of district heating – it has many relationships within several areas. The present thesis will shed some light how the 17 SDGs are related to a local district heating company, the local sugar factory, public transportation and the local grid. To use wood chips for a district heating system seems very common but using a waste product such as methane gas (or something close to it) and convert it into better Compressed Natural Gas (CNG) instead of creating only energy out of it, is a local novum. Sustainable urbanization is a term which is filled with meaning and some aspects of that are described within this essay.

Key Word: energy, district heating, sustainability, smart meter infrastructure, 17 SDGs
