An Empirical Study of Nanowire Technological Trends

This paper follows a bibliometric method for nanowire case to make evident the technological trends; to present the relationship between patents; to help the researchers to discover relatively significant patents and to analyse important relationships between patents to identify those with most commercial potential and those which are critical technologies. This research focuses on the nanowire case study due to fact that this field is one of the most mature nanostructures and is one of the highly invested fields in nanotechnology. In terms of methodological approach, this study uses a different patent collection method than previous studies. This new method offers a new taxonomy that could make a significant impact on accurate patent data quests and increase the reliability of the patent analyses. As patent data are valuable sources of technology innovation and for forecasting technical change, this study utilises nanowire patent documents to pick out the technological trends, to identify nanowire technologies which both have the most commercial potential and which are critical at the organisational, national and international levels.

Quantum-Inspired Blockchain-Based Cybersecurity: Securing Smart Edge Utilities in IoT-Based Smart Cities

Blockchain plays a vital task in cybersecurity. With the exerted efforts for realising large-scale quantum computers, most current cryptographic mechanisms may be hacked. Accordingly, we need a quantum tool utilised for designing blockchain frameworks to have the ability to be executed in the level of digital computers and resist the probable attacks from both digital and quantum computers. Quantum walks may be utilised as a quantum-inspired model for designing new cryptographic algorithms. In this paper, we present a new authentication and encryption protocol based on quantum-inspired quantum walks (QIQW). The proposed protocol is utilized to build a blockchain framework for secure data transmission among IoT devices. Instead of using classical cryptographic hash functions, quantum hash functions based on QIQW are employed for linking blocks of the chain. The main advantages of the presented framework are helping IoT nodes to effectively share their data with other nodes and full control of their records. Security analysis demonstrates that our proposed protocol can defend against message attack and impersonation attacks, thus ensuring secure transmission of data among IoT devices.     

New insights on the utilization of ultrasonicated mustard seed cake: chemical composition and antagonistic potential for root-knot nematode,Meloidogyne javanica

This study focused, for the first time, on the effect of ultrasonic features on the extraction efficiency of secondary metabolites in mustard seed cake(MSC). The nematostatic potential of sonicated seed cake was examined against the second-stage juveniles(J2 s) of root-knot nematode, Meloidogyne javanica. The results show that a 35 ppm(parts per million) concentration of a sonicated extract(SE) sample of MSC caused 65% J2 s mortality at 18 h exposure period in vitro. It also significantly suppressed the root-knot index(RKI=0.94) in tomato roots. The lethal concentration values for SE were 51.76, 29.79, and 13.34 ppm,respectively, at 6, 12, and 18 h of the exposure period, and the lethal concentration values for the non-sonicated extract(NSE)sample were 116.95, 76.38, and 55.59 ppm, respectively, at similar exposure time. Sinapine and gluconapin were identified as the major compounds in ultrasonic-assisted MSC. Because of the high extraction efficiency of metabolites in the SE, all treatments of SE were shown to be antagonistic to J2 s. Thus, this study of ultrasonication activity-based profiling of MSC may help generate target-based compounds at a scale relevant to the control of disease caused by nematodes in economic crops.     

Glial Cells: The other cells of the nervous system

Theodor Schwann, the German physiologist who first propounded the cell theory with M Schieiden, had diverse interests. He was not only the first to isolate the enzyme pepsin, but also investigated muscle contraction and nerve structure. In the mid nineteenth century Schwann discovered that a sheath made up of myelin covered the axons of neurons in the peripheral nervous system (PNS). The cells that form the myelin are today called Schwann cells after him. Today, we know that the Schwann cells not only form the myelin sheath around neurons, but also regulate several neuronal functions and are an indispensable part of the PNS.     

Brain type natriuretic peptide (BNP)—A marker of new millennium in diagnosis of congestive heart failure

The burden of disease in patients with congestive heart failure is high. The future of BNP looks promising as it may be a better diagnostic tool for the diagnosis of CHF in developing countries in new millennium. Natriuretic peptide hormones, a family of vasoactive peptides with many favourable physiological properties, have emerged as important contenders for development of diagnostic tools and therapeutic agents in cardiovascular disease. Measurement of B-type natriuretic peptide has become as an easy-to-perform bedside test. The clinical and diagnostic significance of the measurement of plasma Nt-proBNP in the diseases of the cardiovascular system with particular emphasis on the assessment of patients with heart failure and their effects on predicting survival rate. The plasma levels of Nt-proBrain Natriuretic peptide responds more vigorously after myocardial infarction than those of other natriuretic peptides. This article is an attempt to give a short overview on the utility of BNP-blood levels for the diagnosis and treatment of heart failure     

The case in case-based design of educational software: A methodological interrogation

This research assessed the value of case study methodology in the design of an educational computer simulation. Three sources of knowledge were compared to assess the value of case study: practitioner and programmer knowledge, disciplinary knowledge, and knowledge obtained from a case study of teacher practice. A retrospective analysis revealed that the case study was the source of 16 out of 23 design decisions and therefore was the most significant influence on the design of the simulation. The case study was particularly effective in sensitizing the design team to the classroom context, identifying common and uncommon teacher practices, revealing unexpected dimensions of interactions in the classroom, and generating constructive changes to the design of the simulation. Case studies can significantly enrich the design of educational software and are a promising methodological choice for design teams.

What��s Missing in Model-Based Teaching

In this study, the author investigated how four science teachers employed model-based teaching (MBT) over a 1-year period. The purpose of the research was to develop a baseline of the fundamental and specific dimensions of MBT that are present and absent in science teaching. Teacher interviews, classroom observations, and pre and post-student assessments were gathered. Using a Generate-Evaluate-Modify framework as a theoretical guide, the author identified three fundamental aspects of MBT that were not apparent in an analysis of the teaching methods. Drawing on these findings, the author hypothesizes the consequent impact of the absence of these aspects on MBT on students?? experiences and performance in science. Implications for core science teacher professional development activities on MBT are discussed.     

Frictions that activate change: dynamics of global to local non-governmental organizations for female education and empowerment in China,India, and Pakistan*

This article examines how non-governmental organizations create resources and spaces for girls and women’s education and empowerment in China, India and Pakistan – in the context of global expectations and local state relations as well as cultural norms. We examine the dynamics that foster female empowerment associated with educational attainment. Analysis showed that the five NGO’s responses to enabling and constraining local needs and demands gave rise to productive friction that activated positive development. We conclude that engaging local individuals as managers, teachers or facilitators who can negotiate with international actors and with the state is an effective foundation for maintaining a balance between being accountable to local contingencies and norms and to global social justice principles of the projects. These models indicated that “effective scale” might better be defined as a collaboration between the local and global, rather than “scaling up” in size.

International NGO partnerships with several of state organizations and local leadership can be a catalyst for fundamental change, subject to dynamic engagement with productive friction that activates educational empowerment and social change.
