Opis:: This paper seeks to share the experience of the Ultra Low CO2 Steelmaking programme (ULCOS) established in 2002 by a number of EU members on how to cut down CO2 emission by at least 50 % of the present volume of emission. Global environmental challenge today is the issue of climate change resulting in devastating effects such as flooding in many countries of the world. One of the major causes is the CO2 emission from different industries including iron and steel industries. The total global CO2 emission was put at 29Gt in 2007 and projected to be 37Gt by the 2020. Out of this volume the steel industry accounts for 3-4 % and this call for concern from stakeholders to come up with measures to reduce or control the emission of the green house gas. These measures are necessary considering the growth of the iron and steel industry in the last 50 years. Important items considered include among others carbon emission and recovery, carbon capture and storage and new iron and steel making processes and their potential for CO2 reduction.

Opis:: The paper examines the effects of working capital management on Malaysian SMEs profitability within the sight of control factors measured by the size of the firm, leverage, and sales growth. Secondary data was drowned from Companies Commission of Malaysia, database for 66 SMEs in Malaysia for the period between 2006-2012. Panel data regressions were applied in the analysis. Empirical results established a negative effect of working capital administration measures: Stock Turnover in Days, Days Account Receivables, and Cash Conversion Cycle on SMEs benefit intermediaries, Return on Equity (ROE) and Return on Assets. The results also established a positive effect of Net Operating Profit on Cash Conversion Cycle. Furthermore, the study also revealed a positive effect of Days Account Payables on SME’s Return of Asset and Return of Equity, yet having a negative effect on Net operating Profit. The findings imply that profitability of Malaysian SMEs relies upon effective working capital management. The results imply that Profitability of Malaysian SMEs depends upon effective working capital management. The paper contributes empirical evidence on the effect of working capital on Malaysian SMEs.
Artykuł analizuje wpływ zarządzania kapitałem obrotowym na rentowność w MŚP Malezji pod kątem czynników kontrolnych mierzonych wielkością firmy, dźwignią finansową i wzrostem sprzedaży. Wtórne dane zostały uzyskane z Komisji Firm Malezji, bazy danych dla 66 MŚP w Malezji w latach 2006-2012. W analizie zastosowano regresję danych panelowych. Wyniki empiryczne wykazały negatywny wpływ narzędzi zarządzania kapitałem obrotowym: rotacja zapasów w dniach, należności z tytułu dni płatniczych i cykl konwersji gotówki do pośrednikach świadczeń MŚP, zwrot z kapitału własnego i zwrot z aktywów. Wyniki wykazały również pozytywny wpływ operacji netto. Ponadto, badanie wykazało również pozytywny wpływ zobowiązań z tytułu płatności w dniach na zwroty aktywów i zwrotu kapitałów własnych MŚP, co jednak ma negatywny wpływ na zysk netto z działalności operacyjnej. Wyniki badania sugerują, że rentowność malezyjskich MŚP zależy od Zarządzania kapitałem obrotowym. Wyniki sugerują, że rentowność malezyjskich MŚP zależy od skutecznego zarządzania kapitałem obrotowym. Artykuł ten stanowi dowód empiryczny na temat wpływu kapitału obrotowego na malezyjskie MŚP.

Opis:: An experiment was conducted at Usmanu Danfodiyo University Teaching and Research Farm Sokoto, Nigeria to determine the utilization of Scelocarya birrea kernel meal (SBKM) as protein supplement in the diet of Uda sheep. Sixteen intact male animals were used for the experiment. The animals were divided into four (4) treatment groups replicated five times. The animals were fed diets containing 0, 5, 10 and 15% Scelocarya birrea kernel meal (SBKM). Data generated from the study were subjected to analysis of variance (ANOVA). Where significant difference exists, least significant different (LSD) was used to separate the means. Results indicated that total feed intake increased with increased level of SBKM up to 5% inclusion level; thereafter, it declined (P<0.05). Average daily gain (ADG) decreased from 99.90g/day for treatment 2 (5% SBKM) to 59.5g/day for treatment 4 (15% SBKM) (P< 0.05). Digestibility of dry matter (DM), crude protein (CP), crude fibre (CF), Nitrogen free extract (NFE) and ether extract (EE) were higher for treatment 2 (5% SBKM) (P< 0.05). Cost of fed per kg live weight gain (N 553.33/kg was lower (P<0.05) for treatment 2 (5% SBKM) compared to other treatments. It was concluded that inclusion of SBKM in the diet of Uda sheep should not exceed 5%.

Opis:: A study was conducted in four selected local government areas of Sokoto state in the extreme North-western part of Nigeria to quantify Sclerocarya birrea fruits as feed supplement for ruminant animals. The areas were Kware, Wamakko, Bodinga and Rabah. A check list was used to obtain information from ten respondents from five districts in each local government area making a total of 200 respondents. Information collected includes tree availability, yield and uses. Data generated from the study were subjected to simple descriptive statistics and analysis of variance. Results obtained indicated that 48 % of the respondents reported the availability of S. birrea while 20 % indicated its scarcity. 43 % of the respondents reported the use of S. birrea as food and medicine for animal and man and 10 % reported its use as fuel and wood work. Kware local government had a significantly higher number of S. birrea trees compared to other locations (P<0.05). However, the yield obtainable was significantly higher in Bodinga and Rabah local government areas (P<0.05) compared to Kware and Wamakko. Results indicated that a total of 13,953; 10,377; 11,069 and 9,641 kg of S. birrea could be obtained from Kware, Bodinga, Rabah and Wammako Local Government areas annually. It was concluded that S. birrea is a potential feed supplement in the dry sub-humid zone of Nigeria.

Opis:: Man’s activities on the environment often results in pollution and degradation of water bodies. Water bodies must therefore be jealously guided and protected from being polluted, which will affect water quality and availability for desired usage. Causes of water quality impairment are urban and rural storm water runoff, inadequate waste water treatment, nutrient entrophication, atmospheric deposition and acid rain, pollutant in sediments and fish, and nuisance aquatic weed growth and invasive species. Other factors include unhygienic disposal and inadequate treatment of human and livestock wastes, indecent management and treatment of industrial residues, inappropriate agricultural practices and unsafe solid waste discharge. Suggested strategies to combat water quality problems which should form the basis of policy solution for improving water quality include: (i) prevention of pollution; (ii) treatment of polluted water; (iii) safe use of waste water; and (iv) restoration and protection of ecosystem. It is recommended that our water bodies and the environment in general should be protected through appropriate legislation guidelines and public literacy campaign and mass education to sensitize, educate and make the people a fully environmentally literate society. Taking these steps internationally, nationally and locally will mean better water quality for our present society and future generation.

Opis:: For several decades, Nigerian cities have been experiencing a decline in their biodiversity resulting from rapid land use land cover (LULC) changes. Anticipating short/long-term consequences, this study hypothesised the effects of LULC variables in Akure, a developing tropical rainforest city in south-west Nigeria. A differentiated trend of urban LULC was determined over a period covering 1999–2019. The study showed the net change for bare land, built-up area, cultivated land, forest cover and grassland over the two decades to be -292.68 km2, +325.79 km2, +88.65 km2, +8.62 km2 and -131.38 km2, respectively. With a projected population increase of about 46.85%, the study identified that the built-up land cover increased from 1.98% to 48.61%. The change detection analysis revealed an upsurge in built area class. The expansion indicated a significant inverse correlation with the bare land class (50.97% to 8.66%) and grassland class (36.33% to 17.94%) over the study period. The study observed that the land consumption rate (in hectares) steadily increased by 0.00505, 0.00362 and 0.0687, in the year 1999, 2009 and 2019, respectively. This rate of increase is higher than studies conducted in more populated cities. The Cellular Automata (CA) Markovian analysis predicted a 37.92% growth of the study area will be the built-up area in the next two decades (2039). The 20-year prediction for Akure built-up area is within range when compared to CA Markov prediction for other cities across the globe. The findings of this study will guide future planning for rational LULC
