Students need to be aware of plants in order to learn about, appreciate, care for, and protect them. However, research has found that many children are not aware of the plants in their environment. A way to address this issue might be integration of plants with various disciplines. I investigated the effectiveness of an instructional approach based on integration of botany with chemistry and art for increasing students' awareness of plants. The study was carried out in a science summer school for 10- to 12-year-old students (n = 25). A plant awareness questionnaire and a plant blindness test were used as pretests and posttests to assess the effects of the instruction on the students' plant awareness. Semi-structured interviews were also conducted with the students after instruction. The results indicated that integrating plants with various disciplines might overcome the learning problem of students associated with their "plant blindness." Moreover, this instructional approach can provide students opportunities to learn the names of plants and some concepts in the botanical discipline, as well as help them understand the relationship between plants and other disciplines. © 2015 by National Association of Biology Teachers.

Acupuncture and Electro-Therapeutics Research

Acupuncture is a key component of traditional Chinese medicine involving the insertion of needles through the skin at specific points on the body to achieve therapeutic effects and is an ancient Chinese art of healing. Using ancient scientific principles, acupuncture treats illnesses by bringing a person's body into harmony and regulating the balance of Yin and Yang. Balancing Yin and Yang is one basic principle of Chinese medicine, and balancing methods for combination of meridians and acupoints have been described throughout the history of Chinese medicine. Clinical observations and principal research on acupuncture focus on the adjustment of the Zang-Fu organ and have shown that the adjustment by acupuncture relied largely on the effective components in different organs. What does this effectiveness mean? In fact, is acupuncture a treatment that shows its effects with signals to the autocrine, paracrine and endocrine pathways? What role does embryology play in this area? Furthermore, molecular biology has opened avenues to newer methods for the study of embryology and to enhance our understanding of growth and development. Can evaluation of acupuncture with these branches of science be more scientific? We discuss this interesting topic in this original article. After all this time, it is reasonable that different therapeutic techniques and approaches are developed for acupuncture. Copyright © 2015 Cognizant Communication Corp. Printed in the USA. Source

We report the thermotropic, thermo-morphologic and structural properties of four homologs of (S)-5-alkyloxy-2-[{4-(2-methylbutoxy)phenylimino}methyl]phenol liquid crystalline salicylaldimine compounds, which are firstly synthesized by our group. These compounds are monomorphic mesogens and exhibit the enantiotropic chiral smectic C∗mesophase (SmC∗). Typical textures of the SmC∗mesophase and crystalline state of these new salicylaldimine compounds in large temperature intervals and in heterophase regions of the direct and reverse phase transitions have been investigated in detail. Temperature dependences of the pitch of chiral structure of the SmC∗mesophase and the space period of chiral structure for both heating and cooling processes have been determined. © 2015 Elsevier B.V.

In this work, an elastic-plastic thermal and residual stress analysis were performed for adhesively bonded single lap joint. For this purpose, thermoplastic composite adherents were bonded to each other with epoxy adhesive. Thermoplastic composite material was reinforced by steel-fibres, unidirectionally. Finite element method (FEM) was preferred to obtain thermal elastic and elastic-plastic stress distributions on single lap joint. Accordingly, modelling and solution processes were achieved using ANSYS software. So as to determine effects of uniform temperature loadings on thermal and residual stresses, different values of it were loaded on the joint, uniformly. Briefly, both thermal and residual thermal stresses were calculated under uniform temperature loading which was selected from 40°C to 80°C. According to obtained results different thermal expansion coeffcients of composite adherents and adhesive layer caused thermal and residual stresses on adhesively bonded single lap joint due to applied uniform temperature loadings. Thermal stress values for x and y-directions are very different from each other owing to orthotropic material properties of thermoplastic composite. The magnitudes of elastic analyses results are higher than elastic-plastic analysis results. Contrary to elastic analysis results, elastic-plastic analysis results were nonlinear. Thermal and residual stresses are increased by increasing uniform temperature values, so the highest values were calculated when 80°C. The plastic yielding was firstly come into being for 50°C loading and it is expanded related to raising thermal loadings as nonlinear. Source

Dynamics of orientational and structural transformations between the optical uniaxial and biaxial lyotropic nematic mesophases has been investigated. These transformations have been studied using the polarizing optical microscopy technique and the conoscopic images. Investigations have been carried out both under influence of the external magnetic field and without this field. Dynamics of transformations of the conoscopic images at structural and thermotropic transitions are presented. Source
