The average moisture, crude protein, fiber and carbohydrate, fat and ash content of the FMS were 13.23%, 34.92%, 26.07%, 5.96% and 19.80% respectively. For FF these values were 14.83%, 28.49%, 31.57%, 8.71% and 16.41% respectively. No significant differences was observed in the proximate biochemical composition between FMS and FF. Average total weight gain in 60 days was observed to be 47.22 g and 53.45 g for FMS and FF respectively with no significant difference. The mean instantaneous growth rate per day was found 4.15±0.96% for FMS and 4.32±1.03% for FF respectively. The survival rate was 83% for FMS and 84% for FF respectively. A comparatively lower FCR that achieved with FMS (1.91) over the FF (1.97) suggested that feed mill sweepings can be used as a substitute to formulated feed in GIFT tilapia culture.

As a consequence, MCO has changed Malaysians' norms. Many Malaysians have become compulsive online buyers and the food waste issue has occurred due to the problem of over-purchasing. This study intends to extend the Theory of Planned Behaviour (TPB) in influencing waste separation among households. This study investigates the influence of descriptive norms, personal norms, and cognition of consequences towards the intention to separate waste. This research used a quantitative online survey and convenience sampling. A final and valid sample of 300 households was analysed using Pearson correlation. This research indicates that descriptive norms and cognition of consequences significantly influence the intention of Malaysian households to separate waste. On the other hand, personal norms do not have an influence on the waste separation int...

To deal with this palm waste, researchers are working hard to work out the ways to convert this plentiful waste into useful material for future beneficial applications. The objective of this study was to employ chemical activation techniques to prepare a new activated carbon (AC) using discarded oil palm leaves (OPL) in Malaysia. Three chemical agents (H3PO4, NaOH and ZnCl2), as well as three pyrolysis temperatures (400 °C, 600 °C and 800 °C) and various impregnation ratios (1:0.5–1:3) were used to optimize the preparation process. As a result, the oil palm leaves activated carbon (OPLAC), with prominent surface properties, was obtained by ZnCl2 activations with a 1:1 impregnation ratio and carbonized at a pyrolysis temperature of 800 °C. The OPLAC-ZC had a surface area of 331.153 m2/g, pore size of...

Recent trends in adsorption of hazardous organic pollutants including Polyaromatic Hydrocarbons (... more Recent trends in adsorption of hazardous organic pollutants including Polyaromatic Hydrocarbons (PAHs), Chemical Oxygen Demand (COD), Pharmaceuticals, and Chemical Dyes in wastewater using carbonaceous materials such as activated carbon (AC) and biochar (BC) have been discussed in this paper. Utilization of biomass waste in the preparation of AC and BC has gained a lot of attention recently. This review outlines the techniques used for preparation, modification, characterization, and application of the above-mentioned materials in batch studies. The approaches towards understanding the adsorption mechanisms have also been discussed. It is observed that in the majority of the studies, high removal efficiencies were reported using biowaste adsorbents. Regarding the full potential of adsorption, varying values were obtained that are strongly influenced by the adsorbent preparation technique and adsorption method. In addition, most of the studies were concentrated on the kinetic, isothe...

Our current attempt was made to obtain the ethanolic extracts of medicinal plant Cerastium fontanum using a hot continuous soxhlet process and also via maceration method. The concentrated dried fraction extracts of Cerastium fontanum such as aqueous, n-hexane, ethyl acetate and dichloromethane were achieved using liquid-liquid extraction which were then evaluated for in vitro antioxidants potential using DPPH (1,1-diphenyl-2-picryl-hydrazyl) assay and also agar-well diffusion method were used for antimicrobial potential. In vitro antioxidants inhibition potential were measured through spectrophotometer at various concentration (500 to 62.5µg/mL) prepared in standard solvent. Among all extracts aqueous fraction showed IC50 = 2.9 ± 0.05mg/mL maximum potency towards stable...

Re... more Camel is the best useful addition to the food chain, as it provides milk, meat and byproducts. Recently twenty breeds of camel are documented in Pakistan. The two main types are riverine and mountain camels that are found in sandy deserts, costal mangroves,mountainous tracts and irrigated plains. Socio-economically camel is very important as it is used in drawing water from wells, ploughing, leveling, grinding grains, crushing sugarcane, pulling carts, oil extraction and transportation. A well fed camel can yield 15-20 liter milk daily while growth rate is up to 1 kg per day. Camel milk is used for making yogurt, kurth, butter, ghee, khoa and rabri. Hides, hairs and some fine wool are byproducts of camel. Collaborative research, registration of camel herds, organized marketing, establishment of camel health centers, selection and application of modern breeding techniques, fattening of males, special incentives or hardship allowances and camel ranching schemes are the measures by whi...

This report has been developed as an input to anchor dialogue on the development of the Meghna TBSS. This report has therefore attempted to create a compendium of the Meghna Basin, consolidating information on its geophysical, ecological and cultural value. The report also preliminarily scopes the variety of benefits provided by the basin and articulates the opportunities for joint development of the basin to maximise these benefits, such as improved resilience to flood and erosion, food self-sufficiency and security, and conservation of cultural and ecological diversity. It is hoped that the report will be widely disseminated among the key stakeholders in the Meghna Basin and will be used as a reference point to guide dialogue for the dev...

This study can help to identify the contributing factors towards the production performance. Five factors were identified based on the past literature. 100 food processing manufacturers with the majority coming from small and medium industries (SME) have been selected. The purposive sampling technique has been selected for this study with the total number of usable questionnaires received being from 80 respondents. The collected data was analysed using SmartPLS 3.0 to test the relationships between the independent variables and the dependent variable of the study. The results showed that the Total Quality Management (TQM), Lean Management (LM), and Hazard Analysis and Critical Control Point (HACCP)significantly influenced the production performance. The practical implications of these outcomes are further discussed in the study.

Thetime series data in percentage changes are found stationary. As a result, multivariateVAR in first-difference is implemented since the objective is to investigate the effectsof changes in causal variables on changes in individual selected casino stockreturns. The estimates depict weakly positive and somewhat mixed causal influencesof changes in unemployment rates on changes in casino stock returns. In the caseof the changes in S&P 500, the results are uniformly positive and relatively strong.In other words, the latter unleash stronger influence than the former on changes incasino stock returns with mixed net short-run interactive feedback effects.

This research takes the banking sector into consideration that banking is one of the industries or the most vulnerable institutions for financial incidents due to the many regulations and financial transactions that occur in the banking sector. This study uses banking data from 2014-2017 with a total sample of 90 banks. Data analysis techniques are carried out using multiple regression analysis. The results show that the pressure proxied by external pressure, which is proxied by free cash flow, has a positive effect on fraudulent financial statements, which means that the greater the free cash flow of the banking sector, the greater the likelihood of fraudulent financial statements. Whereas pressure proxied by financial stability, financial targets, and ineffective monitoring and rationalization and good governance have no effect on fraudulent financial statements.
