Effect Of Post Composting On Vermicompost Of Spent Mushroom Substrate, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood Nov 2008

Effect Of Post Composting On Vermicompost Of Spent Mushroom Substrate, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

By using Lumbricus rubellus, vermicomposting started after 3 weeks of pre composting. Five treatments in different ratio of cow dung : spent mushroom substrate were prepared as feed materials with four replicates for each treatment namely; 80:20 (T1), 60:40 (T2), 50:50 (T3), 40:60 (T4) and 20:80 (T5). After 7 weeks of vermicomposting, macronutrient elements of vermicompost produced were measured and the process continues with composting when all the earthworms were taken out from the treatments. Macronutrient elements of compost produced were also measured after 20 weeks of composting. The data reveals that 7 weeks for vermicomposting ...

The present experiment on Staphylococcus epidermis [ATCC –13518], validate the effects of such energy transmitted through a person, Mahendra Trivedi, which has produced an impact measurable in scientifically rigorous manner.

Methods:

Staphylococcus epidermis strains in revived and lyophilized state were subjected to spiritual energy transmitted through thought intervention and/or physical touch of Mahendra Trivedi to the sealed tubes containing strain, the process taking about 3 minutes and were analyzed within ...


Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr Nov 2008

Leading Firms As Knowledge Gatekeepers In A Networked Environment, Deogratias Harorimana Mr

Dr Deogratias Harorimana

This chapter introduces the role of the knowledge gatekeeper as a mechanism by which knowledge is created and transferred in a networked environment. Knowledge creation and transfer are essential for building a knowledge based economy. The chapter considers obstacles that inhibit this process and argues that leading firms create a shared socio-cultural context that enables the condivision of tacit meanings and codification of knowledge. Leading firms act as gatekeepers of knowledge through the creation of shared virtual platforms. There will be a leading firm that connects several networks of clients and suppliers may not interact directly with one another, but ...

A Transcendental To Changing Metal Powder Characteristics, Mahendra Kumar Trivedi Oct 2008

A Transcendental To Changing Metal Powder Characteristics, Mahendra Kumar Trivedi

Mahendra Kumar Trivedi

It’s not often that Metal Powder Report departs from the path of hard facts into the somewhat ‘mushier’ area of metaphysics, but opportunities crop up. While recognising that science has its fair share of charlatans, one such opportunity was presented by a paper submitted by an Indian researcher in which he details work aimed at probing the effects on powder samples where changes were apparently generated by thought. Some will laugh, others will cry, but perhaps among our readers there are those who might be able to help elucidate further the phenomena described…


Intrinsic Severity As A Determinant Of Antiepileptic Drug Refractoriness, Michael A. Rogawski, Michael R. Johnson Sep 2008

Intrinsic Severity As A Determinant Of Antiepileptic Drug Refractoriness, Michael A. Rogawski, Michael R. Johnson

Michael A. Rogawski

For the most part, resistance to medications in epilepsy is independent of the choice of antiepileptic drug. This simple clinical observation constrains the possible biological mechanisms for drug refractory epilepsy by imposing a requirement to explain resistance for a diverse set of chemical structures that act on an even more varied group of molecular targets. To date, research on antiepileptic drug refractoriness has been guided by the “drug transporter overexpression” and the “reduced drug-target sensitivity” hypotheses. These concepts posit that drug refractoriness is a condition separate from the underlying epilepsy. Inadequacies in both hypotheses mandate a fresh approach to the ...


What Clinical Observations On The Epidemiology Of Antiepileptic Drug Intractability Tell Us About The Mechanisms Of Pharmacoresistance, Michael Rogawski Aug 2008

What Clinical Observations On The Epidemiology Of Antiepileptic Drug Intractability Tell Us About The Mechanisms Of Pharmacoresistance, Michael Rogawski

Michael A. Rogawski

In the past several years, there have been important advances in the clinical epidemiology of antiepileptic drug resistance, as reviewed by Mohanraj and Brodie. It would appear that by and large, intractability is independent of the choice of antiepileptic drug (AED). Many patients will become seizure free on the first agent tried, irrespective of which one their physician decides to pick. Nonresponders to the first drug are in a different category: it is likely that they will continue to have seizures no matter which medicine or combination of medicines is tried. This simple clinical observation puts important constraints on the ...

Beyond The Liability Wall: Strengthening Tort Remedies In International Environmental Law, Noah Sachs Apr 2008

Beyond The Liability Wall: Strengthening Tort Remedies In International Environmental Law, Noah Sachs

Noah Sachs

Despite decades of effort, the international community has stumbled in attempts to craft tort remedies for victims of transboundary environmental damage. More than a dozen civil liability treaties have been negotiated that create causes of action and prescribe liability rules, but few have entered into force, and most remain unadopted orphans in international environmental law. In this Article, I explain the problematic record of tort liability regimes by developing a theoretical model of liability negotiations, grounded in regime theory from political science. Based on the model, I conclude that negotiated liability regimes have foundered because of three main roadblocks: 1 ...


Effect Of Tgf-Beta 1 Antisense Oligodeoxynucleotide On Renal Function In Chronic Renal Failure Rats, Kiew Lik Voon Apr 2008

Effect Of Tgf-Beta 1 Antisense Oligodeoxynucleotide On Renal Function In Chronic Renal Failure Rats, Kiew Lik Voon

Kiew Lik Voon

Aim: The aim of the present study was to investigate the effectiveness of transforming growth factor (TGF)-beta 1 antisense oligodeoxynucleotides (ODN) in ameliorating deteriorated kidney function in rats with puromycin-induced chronic renal failure (CRF). Methods: Saline, puromycin, puromycin+TGF-beta 1 antisense ODN or puromycin+scrambled ODN were administered to unilaterally nephrectomized rats. Renal hemodynamic and excretory measurements were taken in the anaesthetized rats that had undergone surgical procedure. Results: It was observed that in the CRF rats, there was a marked reduction in the renal blood flow (RBF), glomerular filtration rate (GFR), severe proteinuria, and almost 6-fold increased fractional ...


Microproteomics: Analysis Of Protein Diversity In Small Samples, Howard B. Gutstein, Jeffrey S. Morris, Suresh P. Annangudi, Jonathan V. Sweedler Feb 2008

Microproteomics: Analysis Of Protein Diversity In Small Samples, Howard B. Gutstein, Jeffrey S. Morris, Suresh P. Annangudi, Jonathan V. Sweedler

Jeffrey S. Morris

Proteomics, the large-scale study of protein expression in organisms, offers the potential to evaluate global changes in protein expression and their post-translational modifications that take place in response to normal or pathological stimuli. One challenge has been the requirement for substantial amounts of tissue in order to perform comprehensive proteomic characterization. In heterogeneous tissues, such as brain, this has limited the application of proteomic methodologies. Efforts to adapt standard methods of tissue sampling, protein extraction, arraying, and identification are reviewed, with an emphasis on those appropriate to smaller samples ranging in size from several microliters down to single cells. The ...


A Preliminary Assessment Of The State Of Harvest And Collection Technology For Forest Residues, Erin G. Wilkerson, D. Brad Blackwelder, Robert D. Perlack, David J. Muth, J. Richard Hess Feb 2008

A Preliminary Assessment Of The State Of Harvest And Collection Technology For Forest Residues, Erin G. Wilkerson, D. Brad Blackwelder, Robert D. Perlack, David J. Muth, J. Richard Hess

David J. Muth

To meet the “Twenty in Ten Initiative” goals set in the 2007 State of the Union address, forest resources will be needed as feedstocks for lignocellulosic ethanol production. It has been estimated that 368 million dry tons can be produced annually in the U.S. from logging residues and fuel treatment thinnings. Currently, very little of this woody biomass is used for energy production due to the costs and difficulty in collecting and transporting this material. However, minimizing biomass costs (including harvest, handling, transport, storage, and processing costs) delivered to the refinery is necessary to develop a sustainable cellulosic ethanol ...


Kinship Foster Care: Implications Of Behavioral Biology Research, David Herring Jan 2008

Kinship Foster Care: Implications Of Behavioral Biology Research, David Herring

David J. Herring

Public child welfare systems rely heavily on kin to serve as foster parents, requiring public actors to consider and choose among different types of available kin (e.g. maternal grandmothers, paternal grandfathers, matrilateral aunts). Behavioral biology researchers have been exploring kinship relationships and the expected level of investment in child care for different types of kin. This paper explains the relevance to kinship foster care of behavioral biology research on kinship relationships and expected levels of parental investment. This research allows for the development of a rank listing of second-degree kin in terms of their likely level of investment in ...


Synthesis And Characterization Of Poly(Allyl Methacrylate) Obtained By Free Radical Initiator., Selda Keskin Jan 2008

Synthesis And Characterization Of Poly(Allyl Methacrylate) Obtained By Free Radical Initiator., Selda Keskin


Allyl methacrylate was polymerized in CCl4 solution by a,a0-azoisobutyronitrile at 50, 60, and 708C. The kinetic curves were autoaccelarated types at 60 and 708C, but almost linear at 508C. Arrhenius activation energy was 77.5 kJ/mol. The polymer was insoluble in common organic solvents. It was characterized by FT-IR, NMR, DSC, TGA and XPS methods. About 98–99% of allyl side groups were remained as pendant even after completion of the polymerization. The spectroscopic and thermal results showed that polymerization is not a cyclopolymerization type, but may have end group cyclization. The high molecular weight is the main ...

Neurosciences And Education: One Example Of A Two-Way Cooperation, Armando F. Rocha, Fábio T. Rocha Jan 2008

Neurosciences And Education: One Example Of A Two-Way Cooperation, Armando F. Rocha, Fábio T. Rocha

Armando F Rocha

The relationship between education and cognitive neuroscience is an old issue from which the idea of the ‘neuroeducators’ was proposed 25 years ago. The premise of this idea is that the knowledge about how the brain operates our learning could help teachers in the classrootm. Despite of being an old issue, there are yet some unsolved matters. Firstly, how neuroscience and education could integrate biological understanding about learning cerebral process has not been yet clearly discussed. The present paper presents the results from Enscer– Teaching the Brain Project – that has been developed in Brazil for five years. During that time ...


Dispelling The Myths Of Machine Translation, Uwe Muegge Jan 2008

Dispelling The Myths Of Machine Translation, Uwe Muegge

Uwe Muegge

It is not surprising that myths, half-truths, and misunderstandings abound regarding machine translation: It seems as if the experience most players in the translation field have with this technology does not go beyond toying a little with one of the free online translation tools. Almost every week, I come across an article informing its readers either that machine translation is and always will be a complete waste of time or that machine translation, while being a waste of time today, might actually be useful some time in the distant future. In the hope of setting the record straight, here is ...

First Report Of Downy Mildew On Lepidium Sativum In India, Kunal Mandal

Kunal Mandal

Downy mildew caused by Hyaloperonospora parasitica on different members of Brassicaceae has been reported from different parts of the world. In India, the pathogen is recorded for the first time on Lepidium sativum. Proper management strategies need to be formulated against this disease as incidence is increasing.


Effect Of Different Levels Of N, P And K On Downy Mildew (Peronospora Plantaginis) And Seed Yield Of Isabgol (Plantago Ovata), Kunal Mandal, R. Saravanan, S. Maiti Jan 2008

Effect Of Different Levels Of N, P And K On Downy Mildew (Peronospora Plantaginis) And Seed Yield Of Isabgol (Plantago Ovata), Kunal Mandal, R. Saravanan, S. Maiti

Kunal Mandal

The study showed that application of different doses of inorganic nutrients had considerable influence on growth, yield and downy mildew interaction in isabgol (Plantago ovata). It included three levels of nitrogen (0, 30, 60 kg N ha–1), two levels of phosphorous (0, 30 kg P ha–1) and two levels of potash (0, 40 kg K ha–1) for 2 consecutive years. The highest N supply (60 kg ha–1) caused more than 65% increase in disease severity compared with the control. However, application of 40 kg K ha–1 reduced percent disease index (PDI) by more than 10 ...


Optimal Switching Control For Microbial Fed-Batch Culture, Chongyang Liu, Zhaohua Gong, Enmin Feng, Hongchao Yin Jan 2008

Optimal Switching Control For Microbial Fed-Batch Culture, Chongyang Liu, Zhaohua Gong, Enmin Feng, Hongchao Yin

Chongyang Liu

In fed-batch culture of glycerol bio-dissimilation to 1,3-propanediol (1,3-PD), the aim of adding glycerol is to obtain as much 1,3-PD as possible. Hence, a proper feed strategy is required during the process. In this paper, we present an optimal switching control model based on our proposed controlled switching system. Some properties of the controlled switching system are obtained. Subsequently, we prove the existence of optimal control. In order to deduce the optimality conditions, we transcribe the optimal switching control model into an equivalent one with fixed switching instants and parameters. Finally, the optimality conditions of the equivalent ...


Identification Of Intracellular Kinetic Parameters In Continuous Bioconversion Of Glycerol By Klebsiella Pneumoniae, Enmin Feng, Chongyang Liu, Zhaohua Gong, Yaqin Sun Jan 2008

Identification Of Intracellular Kinetic Parameters In Continuous Bioconversion Of Glycerol By Klebsiella Pneumoniae, Enmin Feng, Chongyang Liu, Zhaohua Gong, Yaqin Sun

Chongyang Liu

In this paper, we propose a hybrid nonlinear dynamical system to describe the concentration changes of extracellular and intracellular substances of glycerol bioconversion to 1,3- propanedol (1,3-PD) in microbial continuous cultures. It is proved that the solution to the system exists and is continuous with respect to kinetic parameters. Subsequently, a novel quantitative definition of biological robustness is investigated. We present a performance index based on experiment data of extracellular concentrations and biological robustness. Taking the proposed hybrid nonlinear dynamical system as a constraint, we establish an identification model to determine the most reasonable metabolic pathway and optimal ...

The Consequence Of Vermicomposting Duration To Macronutrient Elements – C, N, P And K In Vermicompost, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood Jan 2008

The Consequence Of Vermicomposting Duration To Macronutrient Elements – C, N, P And K In Vermicompost, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

The effect of vermicomposting duration to macronutrient element in vermicompost was investigated. Three different treatments were prepared with eight replicates for each treatment namely cow dung: kitchen waste in 30:70 ratios (T1), cow dung: coffee grounds in 30:70 ratio (T2), and cow dung: kitchen waste: coffee grounds in 30:35:35 ratios (T3). Vermicompost produced by Lumbricus rubellus were analyzed in week tenth and thirtieth. In conclusion, longer duration of vermicomposting will enhance the quality of vermicompost. This is shown by the percentage increase of macronutrient elements (N & P) and declining of C/N ratio.

The Potential Of Coffee Grounds And Kitchen Waste In Vermicomposting, Adi Ainurzaman Jamaludin, Noor Zalina Mahmood

Adi Ainurzaman Jamaludin

Vermicomposting using Lumbricus rubellus for 49 days was conducted after 21 days of pre-composting. Three different combination of treatments were prepared with eight replicates for each treatment namely cow dung : kitchen waste in 30:70 ratio (T1), cow dung : coffee grounds in 30:70 ratio (T2), and cow dung : kitchen waste : coffee grounds in 30:35:35 ratio (T3). At the end of study, there was a significant difference between numbers of earthworms among the three different treatments (p < 0.05). In contrast with weights of earthworms there was no significant difference (p > 0.05) among the three treatments. By comparing the numbers and weights of earthworms in each treatments (T1, T2 & T3) only ...
