Miracle Fruit (Synsepalum dulificum) has been studied because of its unique taste modifying properties. This study investigated contents of phenolics, flavonoids, and antioxidant activities in skin, pulp, and seeds of Miracle Fruit. The free phenolic content in skin was almost 3 times of that in pulp and 4 times of that in seeds. Skin contributed 43.96% of free phenolic compounds with 15.91% of...

Approximately 350 million tons of manure is produced annually by agriculture in the U.S. Manure disposal at large concentrated animal feeding operations presents a challenge. Anaerobic digestion of livestock manure to reduce odor and produce biogas for energy generation is a profitable waste management option on farms, but out of reach of most farmers because of high capital costs. For operatio...

Thermally assisted mechanical dewatering (TAMD) is a new process for energy efficient liquid/solids separation which enhances conventional device efficiency. The main idea of this process is to supply a flow of heat in mechanical dewatering processes to favour the reduction of the liquid content. This is not a new idea but the proposed combination, especially the chosen operating conditions (T ...

This study investigated the chemical and thermal properties of faecal sludge from 10 dry VIP latrines in Bester’s Camp in the eThekwini Municipality, Durban, South Africa. Faecal sludge samples were selected at different depths and from the front and back sections of 10 VIP latrines during a manual emptying process. The samples were analysed for: moisture content; volatile solids; chemical oxyg...

the physical and physiological characteristics of sarawak pineapple were studied at five different stages of growth from one to five months after anthesis. changes in fruit length, diameter, pulp color, pulp firmness, ph, total soluble solids, titratable acidity, ascorbic acid content and antioxidant activity were monitored. the sarawak pineapple exhibited a sigmoid growth pattern during fruit ...

Background: Milk is considered as one of the highly nutritious food for human. This study was undertaken to evaluate the physicochemical as well as the microbial quality of pasteurized milk of different brands available in Chittagong, Bangladesh. Methods: Five types of branded pasteurized liquid milk were collected from retail markets of Chittagong, Bangladesh. Physicochemical analyses were ca...

In this study, the effect of sludge retention time (SRT) on oxic-settling-anoxic (OSA) process was determined using a sequencing batch reactor (SBR) attached to external aerobic/anoxic reactors. The SRT of the external reactors was varied from 10 to 40d. Increasing SRT from 10 to 20d enhanced volatile solids destruction in the external anoxic reactor as evidenced by the release of nutrients, ho...

Vinasses are a residual liquid generated after the production of beverages, such as mezcal and tequila, from agave (Agave L.), sugarcane (Saccharum officinarum L.) or sugar beet (Beta vulgaris L.). These effluents have specific characteristics such as an acidic pH (from 3.9 to 5.1), a high chemical oxygen demand (50,000-95,000 mg L(-1)) and biological oxygen demand content (18,900-78,300 mg L(-...

Leucocyte sodium and potassium content and concentrations were measured along with ouabain-sensitive and ouabain-insensitive rate constants for sodium efflux in 14 controls and 20 black patients with essential hypertension. Leucocyte sodium content was significantly increased in the patients (mean 101.1 +/- 7.8 mmol/kg dry solids v 74.5 +/- 7.6 mmol/kg dry solids; p less than 0.05), whereas the...

In this paper the thrust was on assessing changes occurring during the decomposition of human feces through estimation of changes in some typical characteristic parameters (pH, Electrical conductivity, volatile solids, moisture content, carbon content, nitrogen content, C:N ratio and oxygen uptake rate). For these purpose experiments were performed in plastic reactors at controlled temperature ...
