    Continuous increase in ceramic ware waste from construction and demolition waste without good management practice has resulted in elevated volume of this waste category. However, utilization of this waste in masonry unit production could be a plausible option to solve this menace, particularly, in its ability to enhance masonry unit compressive strength. In this study, ceramic ware waste was utilized for hollow masonry unit production and three different natural fine aggregate to ceramic aggregate mix ratios of 100:0, 90:10, 80:20 and 70:30 were examined. Furthermore, the cement to total aggregate mix ratio considered was 1:7. Sequel to the process of aggregates mixing, casting, and subsequently demoulding, the masonry units were cured for 28 days prior to inspection for compressive test parameters. Results indicated that masonry unit with natural sand to ceramic waste mix ratio of 80:20 has the highest crushing strength at peak, yield and break point which were 60.903kN, 60.493kN and 53.863kN respectively. The compressive stress at peak and break were 6.57MPa and 6.50MPa in that order and Young’s modulus was 0.262GPa. Statistically, there were no significant differences at 95% confidence interval between the aggregate mix masonry units when the compressive strength indices were evaluated. Ceramics ware waste from demolition and construction waste is a suitable co-aggregate in hollow masonry unit production

    Coccinia indica an annual creeper is available all over India and well known for its antidiabetic property. In the present investigation, aqueous extract, and ethanolic extract of the fruits were made using hot extraction procedure using soxhlet apparatus, decoction and maceration. The qualitative phyto-chemical screening procedure was performed on each extract. Phyto-chemical study reveals that carbohydrates, tannins, phenols, alkaloids, saponins was present in both the extracts. An attempt has been made to highlight this folk herbal medicine through present study which will assist in the identification of fresh as well as dried crude samples of fruits anatomically and physiochemically. TLC finger printing and fluorescence analysis of powdered fruits has been conducted and reported .The antidiabetic activity is conducted by enzyme inhibition (α-glycosidase) in invitro method on each extract and ethanolic extract showed significant inhibitio

    Effect of Double-T and V-shaped Pipe Configurations and Perforations on the Quality of Chicken Litter Compost

    Livestock waste management has received much attention because of the huge volume and instability. One of the good management practices adopted to address this menace is composting. This study examined the effect of specialized passively aerated composters on some physicochemical properties of chicken litter.  The composter is made up of six double T and V shaped pipe with three different perforation diameters of 15, 20 and 25 mm. Pile configuration of the developed composters had marked effect on total nitrogen content (p0.05) of the compost subjected to 90 days composting time. The composters had uniform air distribution as pile temperature was not significantly affected by pile configuration, perforation size, and their interactions. Furthermore, both T and V shaped pipe structures reached a thermophilic temperature of 49.0 and 67 oC respectively and the compost stabilized in the 12th week. From the agronomic point of view, V-shaped pipe outperformed double inverted T pipes with perforation sizes of 15 and 20 mm. Overall result from this study suggests that double-T and V-shaped composters are feasible composting systems that can enhance biodegradation, maturation, and stability of chicken litter.Keyword: compost, litter, composter, double-T, pile, perforation

    ABSTRACT A herb is a plant that is valued for flavor, scent, or other qualities. Herbs are used in cooking, as medicines, and for spiritual purposes. From ancient days to now a day, medicinal plants are a potential and useful for the treatment of several diseases and disorders. Main reason behind of that is medicinal plants is not having any side effects. One of the common tropical vegetable is Momordica charnatia, it has been used in various Asian traditional medicine. In this review, we revealed the medicinal potency of Momordica charantia linn

    Sexual behavior and experience of sexual coercion among secondary school students in three states in North Eastern Nigeria

    BACKGROUND: Interest in the reproductive health of adolescents continues to grow throughout the world. Few studies had explored the reproductive health knowledge, sexual behavior and experience of sexual coercion among secondary school students in North Eastern states of Nigeria. The objectives of this descriptive survey were to collect data to plan appropriate interventions that meet the reproductive health knowledge, service and skills needs of students in Bauchi, Borno and Gombe states. METHODS: Face-to-face interviews were conducted for 624 consenting students who were randomly selected from eighteen secondary schools using an 83-item structured questionnaire. Data were collected on demographic profile, reproductive health knowledge, sexual behavior and experience of sexual coercion. RESULTS: The mean age of the respondents was 16.5 years. There were slightly more males (52%) than females (48%). Students' knowledge about reproductive health was generally low even though girls had better knowledge than boys. Thirteen percent of the entire students had had sexual experience; significantly more males (19%) than females (6%) had done so (p < 0.001). Among boys the age at sexual debut ranged from 10–26 with a mean of 15.7 and median of 16. By contrast, the age at first sex among girls ranged from 10 to 18 years with a mean and median of 16.1 and 17 years respectively. Only 24% of those who were sexually active used a condom during their last sexual encounter. Overall 11% of the students reported that they had been tricked into having sex, 9% had experienced unwanted touch of breast and backside, and 5% reported rape. CONCLUSION: Students low reproductive health knowledge and involvement in risky sexual activities predispose them to undesirable reproductive health outcomes

    Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

    Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P &lt; 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P &lt; 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk
