Metal bioaccumulation levels in different organs of three edible fish species from the river Ravi, Pakistan

Metals bioaccumulation in five organs of Cirrhinus  mrigala, Labeo  rohita and Catla catla captured from three industrial and sewage polluted downstream sites (Shahdera = B, Sunder = C and Balloki = D) were compared with a non-industrial upstream site (Siphon = A) during high (post monsoon) and low (winter) flow seasons of river Ravi. Mean concentrations of metals were significantly higher in low flow than the high flow season. Pattern of metal accumulation in the studied organs was: Zn > Fe > Mn > Cu > Cr > Pb > Ni > Hg > Cd. Kidneys showed mostly greater metal bioaccumulation than intestines, hearts, eyes and gills. Among fish species, the highest concentrations (µg/g dry weight) of Cr (3.77), Zn (56.22), Mn (8.95), Ni (1.70) and Hg (1.60) and lowest of Pb (2.53) were detected in C. mrigala whereas Cu (7.19), Fe (62.11) and Pb (2.64) appeared higher while Zn (52.69), Mn (7.82) and Ni (1.41) with lowest concentrations in C. catla. In contrast, lower concentrations of Cd (0.15), Cr (3.16), Cu (7.06) and Fe (54.18) were recorded in L. rohita. Accumulation of the metals was significantly different in organs among the different sampling sites. Based on metals accumulation pattern, second downstream site (Sunder) identified as the most polluted site due to untreated industrial and municipal discharges. Measured elevated levels of metals concentrations in fish organs indicated potential health risks for the fish and the food chain

Actividad antioxidante de extractos de metanol al 80% y al 100% de semillas de cebada (Hordeum vulgare L.): estabilización del aceite de girasol.

The antioxidant potential of 100% and 80% methanol extracts from the seeds of three barley varieties (Jou 83, Jou 87 and Haider 93) was assessed. The extract yields from barley seeds ranged from 3.23% (Haider 93,100% methanol) to 5.31% (Jou 83, 80% methanol). The total phenolic contents, DPPH radical scavenging activity (IC50 values) and inhibition of linoleic acid oxidation of barley seed extracts (BSE) were determined to be 88.1-145.7 mg/100g, 90.8-168.6 μg/mL and 62.6-74.6%, respectively. The antioxidant effectiveness of BSE was also assessed by stabilizing sunflower oil (SFO) with BSE at a concentration of 600 ppm (oil weight basis). The stabilized (treated with extract) and the control (without extract addition) SFO samples were subjected to accelerated (oven heating at 60ºC for 30 days, 8 h heating cycle/day) storage. These were analyzed at regular intervals for the extent of oxidative changes according to the measurements of their contents of peroxide value, para-anisidine value, conjugated dienes and conjugated trienes. Generally, the 80% methanol extract of barely seeds demonstrated better antioxidant action than the 100% methanol extract. The antioxidant activity of BSE was also found to be considerably varied among the varieties tested. The present results suggest that antioxidant extracts from barely seeds might be used to protect vegetable oils from oxidation.El potencial antioxidante de extractos de metanol al 100% y el 80% de semillas de tres variedades de cebada (Jou 83, Jou 87 y Haider 93) fue evaluada. El rendimiento de los extractos de las semillas de cebada vario desde un 3.23% (Haider, 100% methanol) a un 5.31% (Jou 83, 80% metanol). El contenido total de fenoles, la actividad atrapadora del radical DPPH (valores IC50) y la inhibición de la oxidación del ácido linoleico de los extractos de semilla de cebada (BSE) fueron 88.1-145.7 mg/100g, 90.8-168.6 μg/mL y 62.6- 74.6%, respectivamente. La efectividad antioxidante de BSE fue también evaluada mediante su capacidad para estabilizar aceite de girasol con concentraciones de BSE de 600 ppm (respecto al peso del aceite). La muestras estabilizadas (tratadas con extractos) y el control (sin adición de extractos) SFO fueron tratadas bajo condiciones de almacenamiento acelerado (calentamiento en un horno a 60ºC durante 30 días y ciclos de calentamiento de 8 h/día). Estas fueron analizadas a intervalos regulares para evaluar la extensión de los cambios oxidativos mediante la medida del valor de peróxidos, valor de para-anisidina y los contenidos de dienos conjugados y trienos congujados. Generalmente, los extractos de semilla de cebada al 80% demostraron una mejor acción antioxidante que los extracto al 100% de metanol. La actividad antioxidante de BSE varió también considerablemente entre las distintas variedades ensayadas. Los presentes resultados sugieren que los extractos antioxidantes de semillas de cebada podrían ser usadas para proteger aceites vegetales de la oxidación

Comparison of new and previous Net Energy Metering (NEM) scheme in Malaysia

Net Energy Metering (NEM) scheme was introduced in Malaysia in 2016 to replace the previous Feed in Tariff (FIT) scheme. NEM allows electricity consumers to generate, use and export the net excess energy to the grid. For the net excess energy exported to the grid, the consumer will be paid base on the displaced cost per kWh unit. However, after two years of implementation, not many consumers engaged with the NEM scheme as compared to the previous FIT scheme due to the poor financial return. Beginning 2019, new NEM scheme (NEM 2019) is introduced to replace the previous NEM 2016 scheme. This paper will investigate the potential financial return of the new NEM 2019 in term of net present cost (NPC) and electricity cost savings. The analysis is conducted by using HOMER software on three different size of residential customers; large, medium and small. Different photovoltaic (PV) panel sizes ranging from 1kWp to 8kWp were used in the analysis. The results show that the NEM 2019 produced lower NPC as compared to NEM 2016 for most cases

Phosphorus and eutrophication in water

Since early 1970, the presence of phosphorus (P) in domestic wastewater has attracted attention due to the awareness of its adverse impacts on the environment, specifically in receiving water such as a river. In the wastewater treatment system, P is a crucial nutrient for bacteria required to degrade and biologically stabilise the organic wastes (Hussain et al., 2001). P is a key nutrient that stimulates the growth of algae and other biological organisms (Mainstone and Parr, 2002). P appears exclusively as orthophosphate, condensed phosphates (polyphosphates), and organically bound phosphate. Condensed phosphates are utilised in cleaning products, and organic phosphates are elements of the body and food waste (Howard, 1985). According to Tjandraatmadja et al. (2010), household products can be a significant contributor to the P load in domestic wastewater. The release of high quantities of P from domestic wastewater treatment plants is of concern, as it is one of the key nutrients that have the potential to contribute to eutrophication in surface water, which can result in excessive growth of algae (Daniel et al., 1994)

Ibn Fadlan's role in the Islamisation of Bulghar society

Islam is the oldest established religion among Bulghar entity, the residents along the riverbanks of the Volga-Kama triangle. This valley was famous as the first Islamic country erected in the Eastern European region. The presence of Islam in the region has raised the name of the ruler of Volga Bulgaria and was reinforced by relationship with Baghdad. The Islamisation of the Bulghar society is relevant to the role played by Ahmad ibn Fadlan, the ambassador of the Abbasid government based in Baghdad. Therefore, this article aims to examine the role played by Ibn Fadlan in the Islamization of the Bulghar society. For this study, a qualitative method using historical descriptive approach was employed, which involved compilation and evaluation of the facts of the Risalah Ibn Fadlān. Data for this study were obtained through library research. The data analyses were conducted through texts and document analyses, as well as comparison method. This study finds that Ibn Fadlan plays an important role in the islamisation of the Bulghar society, not just as an ambassador of Abbasid government but as a teacher, preacher and counselor to the Bulghar king and the whole nation

Integration of time of use (TOU) tariff in net energy metering (NEM) scheme for electricity customers

The introduction of Net Energy Metering (NEM) scheme for electricity customers in Malaysia is seen as an improvement from the previous Feed-In Tariff (FIT). However, the new NEM scheme only benefited the large residential customers but not to medium and small residential customers. Due to electricity tariff blocks structure, the large customers can avoid paying expensive tariff and hence reducing their electricity bill. This is not the case for medium and small customers since they are already paying lower tariff blocks due to their lower electricity consumption. This issue will discourage most residential customers to install solar PV system in their home and affect the Malaysia’s renewable energy target. This paper proposed a NEM scheme that integrates Time of Use (TOU) electricity tariff to the scheme. The proposed NEM-TOU scheme will be simulated, tested and compared to the new NEM scheme by using practical small, medium and large residential customers’ data. The results show that the proposed TOU-NEM scheme able to overcome the weakness of the current scheme where all customers (large, medium and low) can benefited by installing solar PV system in their home

BIOCHEMICAL ANALYSIS OF LOCALLY AVAILABLE FISH FEED INGREDIENTS IN LAHORE, PAKISTAN

Abstract: The present study was conducted to analyze the nutritional value and quality of fish feed ingredients which are commercially used by fish farmers. For biochemical analysis the fish feed samples were collected from local market in Lahore. Samples were prepared, ground and analyzed for evaluation of parameters viz., moisture, crude protein, ether extract, ash, crude fiber and nitrogen free extract by using food and agriculture organization (FAO) standard methods. Comparisons were made for observed values with the standards given by FAO. The results obtained indicated that the nutritional values of the commercially available fish feed ingredients was comparable with the standard values. Minor differences observed during analysis may be due to errors in handling, temperature control, humidity and low quality raw material. The results of analysis reveal that quality of fish feed formulation. The availability of good quality raw material at an affordable price must e ensured for achieving high yields and optimum growth of fish stocks in public and private sector fish farms. It is further concluded that quality control laboratories should be established at regional level to ensure the good quality of raw material involved in fish feed preparations

Board characteristics and real performance in Malaysian state-owned enterprises (SOEs)

Purpose The purpose of this paper is to investigate the relationship between board characteristics and real performance among state-owned enterprises (SOEs) in Malaysia in a longitudinal period following the introduction of transformation policy. Design/methodology/approach The study deviates from prior research in utilising a real performance measure rather than traditional measures of performance. The authors adopt the quantile regression approach to examine the impact of board characteristics on real performance in a comparison using ordinary least squares. Findings The results of quantile regression reveal that the impact of board mechanisms on real performance was not as expected. Specifically, board size and duality had a bearing on real performance. Board independence also is considered as influential factor through the time. However, such effects were not homogenous across different quantiles. The dummy year variable to compare the period pre- and post-transformation policy reveals that the dummy year is not significant, indicating that performance post-transformation is indifferent compared to the pre-transformation policy period. Practical implications It is important for government to reconsider the policies embedded in the transformation policy. This study provides insights on the enhancement of board effectiveness and new developments regarding GLCs. Originality/value This is an early to attempt to measure real performance and its link to board characteristics in SOEs post-transformation policy
