Removal of Nickel from Plating Wastewater Using the Magnetic Flocculant PG-M

Abstracts

In this study, a new kind of magnetic particle functionalized biopolymer (PG-M) was applied to remove nickel from plating wastewater. The key parameters of pH, adsorption time, the mass of adsorbent, and shaking speed were investigated to optimize conditions. Batch experiments were conducted with actual samples collected from a manufacturer having an initial nickel concentration of 143.73 mg/L at pH 5. The highest removal efficiency of Ni2+ ions was greater than 99% when 1 g/L of the PG-M material was added to the solution (pH=10) and stirred at 200 rpm for 20 min. The desorption of this adsorbent was performed in a 0.1 M solution of HCl and the removal efficiency of Ni2+ ions unchanged after nine cycles. The Ni2+-loaded PG-M magnetic flocculant was easily separated from the solution by an external magnet.

Shiga Toxin Producing Strains of Escherichia coli (STEC) Associated with Beef Products and Its Potential Pathogenic Effect

Abstracts

Background: Contaminated beef products sold in Nigeria are widely consumed by all with little or no knowledge of the presence or occurrence of possible pathogen.

Methods: The current study investigated the presence of shiga toxin producing strains of E. coli(STEC) in beef products using selective and chromogenic media. Furthermore, the pathogenicity of STEC was determined in vivo using established methods.

Results: E. coli was isolated from all beef samples while 30 % (mean) were reported to be STEC. There was a dose-dependent increase in the levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase observed in the serum of all mice exposed to STEC. This was also confirmed by an obvious damage in the livers and kidneys of the affected mice.

Conclusion: By and large, the result of this study shows that beef products sold in Benin City, Edo State, Nigeria are loaded with STEC, which could pose grave problem for consumers. Hence, effort should be made to minimize their presence in beef, and to prevent possible outbreaks.

Neofusiccocum parvum as Uncommon Fungal Species (or Emerging Pathogen) on Strawberry Plants in Morocco

Abstracts

During a survey on fungi associated with decline symptoms on strawberry plant of Venicia variety, one species belonging to the Botryosphaeriaceae family was isolated. Based on morphological and cultural characteristics, this species identified as Neofusicoccum parvum was reported for the first time in Morocco. To verify the pathogenicity of the fungus, detached leaves of three strawberry varieties were inoculated artificially by depositing over their intact surface mycelia plug or conidial suspension from Nparvum. Severity index was greater on festival leaves reaching 88% compared to 77.73% on Sabrina. In the third treatment, Guariguette showed a low susceptibility with a severity index in order of 25.07%. Conidia concentration on the leaf surface of the Festival and Sabrina strawberry leaves was respectively 1.62 105 and 1.2 105 conidia cm-2. Otherwise, in the second treatment, it has been reduced to less than 1.41105 1.16 and 105 conidia.cm-2 on leaves of Festival and Sabrina respectively. After inoculation, the fungus was re-isolated from the lesions to verify Koch’s postulates.

Assessment of Levels of Heavy Metals in Paints from Interior Walls and Indoor Dust from Residential Houses in Nairobi City County, Kenya

Abstracts

Aim: This study assessed the levels of Pb, Cr, Cd and Zn in settled indoor dust and paint chips.

Study Design: Samples were obtained from twelve selected residential houses within Nairobi County, Kenya.

Place and Duration of Study: GoK Laboratories, Department of Chemistry, JKUAT between February 2016 and November 2016.

Methodology: A modified version of EPA method SW846 3050B was used to digest the samples, and Flame Atomic Absorption Spectrophotometer (Shimadzu AAS-6200) used to analyze samples for the metals. Pearson correlation coefficient was determined for the various metal pairs in paint chips as well as in the dust samples. Also, it was calculated for the given metals in the dust and paint chips samples from a particular sampling point.

Results: The mean concentration of the metals in both the dust and paint chip samples were in the order Zn>Pb>Cr>Cd. The mean concentrations of Zn, Pb, Cr and Cd  were 366.14 µg/g, 129.12 µg/g, 82.65 µg/g, and 27.40 µg/g for the dust samples and 321.77 µg/g, 289.59 µg/g, 77.54 µg/g, and 73.45 µg/g for the paint chip samples respectively. Pb, Cd, and Zn in the paint chips showed a negative relationship while Cr had a positive correlation.

Conclusion: The metals in the paint chips were found to be of common origin while the correlation of the various metal pairs in the dust suggested more diverse sources. Paint from interior walls is not the only contributor of heavy metals in the settled indoor dust.

Association of Soil Parameters with Various Age Classes of Forests of Mukundpur, Satna, Forest Division, Madhya Pradesh, India

Abstracts

Aims: This forest area was susceptible to illicit felling, encroachment and illicit mining. From this problem the forests are changing from stocked – under stocked – blank forests. The majority of the area are blank and under stocked category. To re-vegetate the blank and under stocked area into stocked forests, the soil parameters in the study area were needed to be studied in detail. In the present study the associations of soil parameters like pH, electrical conductivity, availability of major nutrients (nitrogen, phosphorous and potassium) and micro nutrients like (copper, manganese, iron and zinc) with various age classes of forests were analyzed.

Study Design: Stratified systematic random sampling.

Place and Duration of Study: Study area was the forest area of 111.55 km2 of Mukundpur range of Satna Forest division, Madhya Pradesh, India. Field work was carried out during October 2015 to January 2016.

Methodology: The vegetation sampling had been done to assess the forest resource survey. Stratified systematic random sampling method was used for sampling the vegetation. The minimum numbers of sample points were calculated using statistical formula. The 151 sample points at 30”x 30” were selected on safer side with the help of GPS. Half kg of soil sample was collected from central quadrat from the depth of 30 cm from the sample point and air-dried under shade. These samples were sent to soil testing lab Rewa to assess the soil parameters pH, electrical conductivity, organic carbon, available nitrogen, available P2O5, available K2O and micronutrient analysis for availability of zinc, iron, manganese and copper. The Microsoft access program was developed to evaluate the above soil parameters in various age classes of forests. Age classes of forest are defined as, Mature: where average girth of forest trees is more than 120 cm, Middle age: where the average girth of trees of a particular forest stands between 61-120 cm, Young age: where average girth of trees of particular stand is below 60 cm.

Results: Results of individual soil parameters on various age classes of forests were summarized below:

The average value of pH in different age classes did not change significantly with average value of pH of the study area. The electrical conductivity within encroachment and blank category significantly changed but in medium and young age classes it did not differ significantly with average electrical conductivity of the study area. In encroachment and blank organic carbon content and available nitrogen were significantly higher but in medium and young age classes these parameters did not change significantly with the average value of organic carbon content and available nitrogen of the study area. The average value of available phosphorous in blank and young age classes did not change significantly but in encroachment and medium young age class it was significantly higher than the average value of available phosphorous of the whole study area. The average value of available K2O in encroachment, blank and young age class did not change significantly but it changed significantly in medium age class with average K2O value of study area. Except the encroachment category, the average zinc and iron value in blank, medium and young age classes did not change significantly with average value of the study area. The average value of Mn in encroachment and blank varied significantly but in medium and young category it did not change significantly with the average value of the study area. The average values of Cu with in Blank and young age classes did not change significantly but it had changed significantly in encroachment in medium age class with average value of the study area.

The results of combined effects of pH, EC, Organic Carbon and combined impact of nitrogen, P2O5and K2O (macro nutrients) did not have significant association within various age classes of study area. The results of combined effects of Zn, Fe, Mn and Cu did not have significant association within various age classes of study area.

Conclusion: The effects of pH, electrical conductivity and organic carbon were not significant in age classes of study area either individually or jointly. The available nitrogen did not play significant role in age class formation of forest but P2Oand K2O did make significant impact on medium age classes individually, but the combined effects of nitrogen, P2O5 and K2O (macro nutrients) did not have significant association within various age classes of study area. Individually the Zn, Fe and Mn did not play significant impact on age class formation of the forest, though Cu is significant in medium age classes. The overall impacts of Zn, Fe, Mn and Cu did not have significant association within various age classes of study area.

Industrial Sustainability and the Circular Economy as Counterparts to the Self-referral Mechanics of Natural Law: Part I—A Theoretical Foundation

Abstracts

In Maharishi Vedic Science, the self-referral mechanics of Natural Law are considered fundamental to any complete understanding of nature’s functioning, since Natural Law is understood to be the unmanifest (i.e., non-physical) home of all the laws of nature and the unbounded source of order and intelligence responsible for creating and guiding the physical universe. This proposition is recognizable in modern scientific theories of the ‘unified field’. Moreover, the circular structure and self-referral loops of Natural Law are said to underlie and guide every level of a manifest hierarchy. Among the hallmarks of industrial sustainability are its emphasis on harnessing renewable energy and recycling principles, both designed to limit the impact of polluting activities on the environment and to improve commercial performance. To circumvent the so-called ‘take, make, dispose’ linear economic mentality of the past, contemporary industry has also begun embracing models of circular economy, in which materials and energy are circulated and cascaded through the economic system, with waste either minimized, reused or eliminated altogether. The self-referential nature of recycling and the cascading circularity of circular economies thus bear a prima facie similarity to how Natural Law is structured and functions in continuous self-referral loops.

For that reason, in this Part I of a two-part series of research papers, we explore the fundamental nature of industrial sustainability and circular economy, showing them to be counterparts to the self-referral feedback mechanism of Natural Law as described in Maharishi Vedic Science.

Keywords :

Industrial sustainability; circular economy; Maharishi Vedic Science; self-referral; natural law.
