on sulphonamide drugs, presenting the subject from bacteriological, chemical, pharmacological and clinical aspects. There is also a chapter on antibiotic substances. This research originated from the observation of Van Luijte that micro-organisms from the soil, particularly penicillum expanseum, are capable of producing substances antagonistic to plant parasites. The antibiotic factor, named ' ...

What powered Einstein’s discoveries? Was it asking naïve questions, stubbornly? Was it a mischievous urge to break rules? Was it the destructive power of operational thinking? It was none of these. Rather, Einstein made his discoveries through lengthy, mundane investigations, pursued with tenacity and discipline. We have been led to think otherwise in part through Einstein’s brilliance at recou...

In this presentation I argue that social presence is an important feature of any successful learning activity, particularly within digital learning environments (DLEs). I also contend that the psychological processes that occur during learning should be acknowledged, measured and understood, if we are to design better and more effective DLEs. I argue that social presence and several other key f...

The tenacity of this paper is logical investigation of prevailing ANPR system research by cataloguing existing methods analyzing and equate old and new techniques. Automatic number plate recognition is a technique to read character from image and isolate number using various processes and practices. Automatic number plate credit is a image processing techniques. In this paper we used efficient ...

This paper describes a method for preparing chitosan fibers modified with hydroxyapatite (HAp), tricalcium phosphate (β-TCP), and HAp/β-TCP nanoparticles. Fiber-grade chitosan derived from the northern shrimp (Pandalus borealis) and nanoparticles of tricalcium phosphate (β-TCP) and hydroxyapatite (HAp) suspended in a diluted chitosan solution were used in the investigation. Diluted chitosan sol...

In the face of bizarre challenges, many Nigerian higher education students are surviving out of sure doggedness and determination to succeed. Out of improvisation, deprivation and sheer hard work, many students have attained graduation with outstanding qualities. This study employs autoethnography to report the author’s personal narrative of graduating in mathematics education in a public unive...

The hallucinations and illusions of melancholic monomania (lypemania of Esquirol) are characterized by fixity, intensity, and tenacity, as well as by expression, which distinguish them from those observed in acute delirium and mania. The integrity of the reasoning power, excepting always some obscured portions, "permits lis in most cases to analyse the phenomena and follow their modifications w...

New Testament scholarship commonly maintains with dogmatic tenacity that Paul anticipated the end of world history ("this age"; hz,.ha MlAOfhA) and the consummate inauguration of "the age to come" (MlAOfhA xBAha) within his own lifetime even though he proclaimed that the salvific realities of the coming Age proleptically had been inaugurated in the person and work of Christ, from whom NT eschat...

Carbon fiber fabrics are important engineering materials. However, it is confusing to classify different carbon fiber fabrics, leading to risks in engineering processes. Here, a classification method for four types of carbon fiber fabrics is proposed using artificial neural networks (ANNs) and support vector machine (SVM) based on 229 experimental data groups. Sample width, breaking strength an...
