Monitoring of neck activity for early warning of cervical spondylosis

<abstract> <p>Wireless body area networks (WBANs) is a new research hotspot with great development prospects. The non-contact sensing based on radio frequency signal can solve the issues of personal comfort and privacy. Detection of cervical motion range and cervical strain in time are important in diagnosis and prevention of cervical spondylosis. In this paper, channel state information is used to achieve smart perception and monitoring, timely and efficient detection of different postures and abnormal bending of the neck. It provides an efficient way for protecting cervical health, and also some help for doctors to understand the causes of cervical vertebral disease in a timely manner. The classification accuracy of the four activities reached 99.4%, 99.7%, 99.5% and 99.3%, respectively.</p> </abstract>

Histochemistry for nanomedicine: Novelty in tradition

During the last two centuries, histochemistry has provided significant advancements in many fields of life sciences. After a period of neglect due to the great development of biomolecular techniques, the histochemical approach has been reappraised and is now widely applied in the field of nanomedicine. In fact, the novel nanoconstructs intended for biomedical purposes must be visualized to test their interaction with tissue and cell components. To this aim, several long-established staining methods have been re-discovered and re-interpreted in an unconventional way for unequivocal identification of nanoparticulates at both light and transmission electron microscopy.

Research on the development of the Chinese higher education system during the anti-Japanese war period, 1937-1945

The ancient dynasty was deposed in 1911, and a new republic took its place. It is found that China made great development in all areas of life throughout the Republican era (1912-1949) excepting Anti-Japanese War. During the time when the last Quing dynasty would approach its end, China is in the primary stage in building a higher education system. In a republican era, China developed its modern higher education system which is composed of public universities, private, universities, and voluntary universities. The war with Japan was certainly the most momentous event in the History of China during the Republican era. The methodology indicating the Reformation era is thoroughly examined during the war. The new development of the war has highlighted a higher education system. Consequently, this paper examines the evolution of China's higher education system from 1937 to 1945, during Japan's anti-war era. In this paper, a descriptive methodology is used to get reliable results. Besides, secondary data such as journals, peer-review, papers, books, articles, were used to get information for the topic.

An inquiry into the effectiveness of school broadcasting

Despite the great development of school broadcasting in recent years, the early stages of it growth were beset with difficulties. Low powered stations, high price sets, varied reception, which naturally followed from the geographical configuration of the country (broadcast having to cover many degrees of latitude), times of depression when school subsidies were withdrawn, all these things - in addition to the skepticism which ever attends any innovation- militated against the development of school radio.

Study on the Application of Drying Furnace Waste Gas Treatment Technology in Painting Workshop

With the continuous development of our country's economy, the demand for automobile is higher and higher after people's living standard is improving day by day. In just 40 years of reform and opening up, China's automobile production and per capita possession have made a qualitative leap and a breakthrough in quantity. Greatly promoted the automobile industry's great development.

Polymeric Micelles: A Promising Pathway for Dermal Drug Delivery

Nanotechnology is an area in great development and with application in the most varied fields of science, including cosmetic and pharmaceutical industries. Because conventional formulations for topical application are not always able to effectively penetrate the physical barrier that human skin exerts against factors and compounds of the external environment, polymeric micelles appear as alternative carriers for drugs and active ingredients delivery, also allowing ingredients with lower solubility and higher lipophilicity to be delivered. In fact, the augmented bioavailability of drugs, greater efficacy even at a lower dose, and selective drug delivery in specific organelles are very interesting advantages of the polymeric micelles usage in cutaneous application. As a consequence, they show a reduction in many of the local and systemic adverse effects, which might lead to an increase in patient compliance to the therapeutics, constituting a promising alternative to conventional topical formulations.

Status Quo, Development and Utilization Efficiencies of Wind Power in China

As a kind of green and pollution-free renewable energy, wind energy has great development prospects. How to promote the development of the wind power industry and improve the efficiency of wind power development and utilization is an urgent problem that needs to be solved. On the basis of analyzing the current situation of China’s power development, especially wind power development, a data envelopment analysis (DEA) method was used to analyze China’s wind power development and utilization efficiencies from 2005 to 2020. The results show that the development efficiency of China’s wind power was mainly affected by pure technical efficiency, while the utilization efficiency of China’s wind power was mainly affected by scale efficiency. Therefore, when considering wind power development, the management of wind power development should be strengthened, in order to realize the optimal allocation of resources. In terms of wind power utilization, the output scale of wind power utilization should be expanded to increase the contribution of wind power products to the national economy.

TAHLILUL MAWAD DIRASIYAH FI KITABI TA'LIMI AL LUGHAH AL ARABIYAH

The teaching of the Arabic language had a great development from its experts from all sides in Indonesia, in strategy, method and method, even the vertical books that teachers used in education. before using the textbook. There must be analyzed and observed first. Is the book suitable for education or was not fit. Because many of the teachers complain about the problems they faced in education, the causes of which are the textbooks in which the subjects were not appropriate and in conformity with the rules of teaching the Arabic language. Therefore, the researcher would like to analyze the contents of this book in order to know whether the book is worth using in education or is it not suitable for teaching. This study aims to analyze the study materials in the book "Teaching the Arabic Language for Secondary Schools" in order to know whether the materials included in this book are appropriate to the Arabic educational rules. Or was it not appropriate to the correct educational rules in the Arabic language? The researcher uses the qualitative descriptive method in the library method.

Detection methods for springback of assembled camshaft under hydraulic expansion

The assembled camshaft under hydraulic expansion has the advantages of low cost, lightweight and high performance, which is an advanced technology with great development potential. By applying the tube hydroforming to the fabrication of assembled camshaft, the expansion principle is due to the different degrees of resilience of the cam and the shaft. Therefore, the effective detection method of elastic recovery of camshaft is of great significance to research how to improve the connection strength of the assembled camshaft. This paper introduces several springback detection methods for assembled camshaft under hydraulic expansion, namely resistance strain detection method, gap dynamic detection method and finite element simulation.
