Growth, Nutrient Content and SPAD Value of Corn in Monoculture and in Intercropping  [PDF]
Anna Christina Sanazário de Oliveira, Fábio Cunha Coelho, Henrique Duarte Vieira, Jocarla Ambrosim Crevelari, Raquel Fialho Rubim
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.518288
Abstract:

The objective of this study was to evaluate the growth, the nutrition, and the intensity of the green color in corn plants in monoculture and in intercropping with Mucuna aterrima, Crotalaria juncea, and Canavalia ensiformis, cultivated with different handlings. In general, corn plants in monoculture demonstrated greater growth and greater SPAD value in the first evaluation, despite presenting lower tenor of phosphorus in the leaves when related to the corn in intercropping. The weed helps in the growth of the corn plant and increases the SPAD value during flowering. The monoculture NPK (Nitrogen, Phosphorus and Potassium) fertilization promoted higher values in corn plant growth, as well as a greater SPAD value, at 30 d.a.e., of the plants. The NPK-fertilized corn plants showed a greater tenor of sulphur and a lower tenor of molybdenum. The corn in intercropping with M. aterrima resulted in smaller plants at 70 d.a.e. It also presented a greater tenor of molybdenum and lower tenor of nickel when compared to intercroppings with C. juncea and with C. ensiformis. The corn plants in a intercropping with Crotalaria juncea presented higher growth at 30 and 70 d.a.e. and greater tenors of molybdenum when compared to the plants in intercropping with C. ensiformis.

Influence of Insertion of the Last Sense Codon on Expression Efficiency of Green Fluorescent Protein Gene in Escherichia coli  [PDF]
Xiaoliang Hao, Shota Inoue, Masahide Ishikawa
Journal of Materials Science and Chemical Engineering (MSCE) , 2015, DOI: 10.4236/msce.2015.36003
Abstract:

We studied the relationship between insertion of the last sense codon (i.e., the codon preceding the stop codon) and the efficiency of gene expression. We inserted 64 kinds of last sense codon at the 5’ end of the stop codon of the green fluorescent protein (GFP) gene and introduced the modified GFP genes into Escherichia coli (E. coli). Measuring the fluorescence intensity of the GFP produced in E. coli showed that the last sense codon influenced GFP gene expression and when CCG was inserted as the last sense codon, fluorescence intensity of E. coli was increased to 2.09 fold. On the other hand, insertion of CUA caused decrease of fluorescence intensity to 0.33 fold. We hope that our findings, which may be applicable to gene engineering, will be useful for further studies of protein expression.

Qualitative evaluation of Chang method of attenuation correction on heart SPECT by using custom made heart phantom
Takavar A,Eftekhari M,Beiki D,Saghari M
Iranian Journal of Nuclear Medicine , 2003,
Abstract: SPECT detects γ-rays from administered radiopharmaceutical within the patient body. γ-rays pass through different tissues before reaching detectors and are attenuated. Attenuation can cause artifacts; therefore different methods are used to minimize attenuation effects. In our study efficacy of Chang method was evaluated for attenuation purpose, using a custom made heart phantom. Due to different tissues surrounding heart, attenuation is not uniform more over activity distribution around heart is also non-uniform. In Chang method, distribution of radioactivity and attenuation due to the surrounding tissue is considered uniform. Our phantom is a piece of plastic producing similar SPECT image as left ventricle. A dual head, ADAC system was used in our study. Images were taken by 180° (Limited angle) and 360° (Total rotation). Images are compared with and without attenuation correction. Our results indicate that Chang attenuation correction method is not capable of eliminating attenuation artifact completely in particular attenuation effects caused by breast.
Green Logistics: the Carbon Agenda
LogForum , 2010,
Abstract: Over the next few decades European companies will come under intense pressure to cut their greenhouse gas (GHG) emissions in an effort to achieve very ambitious carbon reduction targets at national, EU and global levels by 2050. This paper presents a framework for the decarbonisation of their logistical activities based on five key freight transport parameters: freight transport intensity, modal split, vehicle utilization, energy efficiency and the carbon intensity of the energy used in logistics. It examines the potential to cut GHG emissions by altering each of these parameters. Consideration is also given to the decarbonisation of warehousing operations. It is concluded that many of the GHG-reduction measures will also yield financial benefit. The decarbonisation of other sectors of the economy may, however, generate greater demand for logistics services.

Journal of Human Resource and Sustainability Studies (JHRSS) , 2019, DOI: 10.4236/jhrss.2019.71005
Abstract: Based on high-order theory and green supply chain management theory, this paper takes 251 manufacturing enterprises in China, the United States and Vietnam as samples to study the impact of corporate Top Management Characteristic on green supply chain management, and green supply chain management and enterprises, and then introduces competition intensity to explore whether it plays a moderating role in the relationship between GSCM and firm performance. The results show that the age, education level and tenure of executives significantly positively affect green supply chain management practices; green supply chain management practices have a positive impact on corporate environmental performance; while green supply chain management practices cannot directly improve economic performance. However, it can promote economic performance by improving environmental performance; competition intensity plays a positive role in the relationship between green supply chain management practices and economic performance.

Abstract: The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1649068103671302 webciteDespite the exceptional utility of genomics methods in the discovery phase of experimentation, these technologies require validation due to problems including misidentification of nucleic acid probes on gene expression microarrays [1,2], non-specificity of probes [3], and the essentially unavoidable false discovery rates associated with massive multiple hypothesis testing [4]. Appropriately powered studies to validate initial results of genomics studies often are lacking [5] or fail to confirm initial discovery-phase results [6], limiting clinical implementation of new disease biomarkers.Immunohistochemistry (IHC) is an important technique for biomarker validation for several reasons. First, it allows direct visualization of biomarker expression in histologically relevant regions of the examined tissue. This is an important advantage over “grind and bind” assays in which tissue is solubilized for biochemical analysis, which may lead to false negative results if few biomarker-positive cells are present in a background of biomarker-negative tissue elements [7]. Second, clinical laboratories typically perform IHC on FFPE tissue sections processed by standard methods, making potentially available hundreds of millions of specimens for study [8]. Third, validated IHC assays may be implemented readily into clinical practice. For example, genomics methods were used to discover mRNA biomarkers capable of subclassifying diffuse large B cell lymphoma (DLBCL) into prognostically discrete subtypes [9]. Relevant subsets of these gene products were validated at the protein level using IHC on large numbers of DLBCL specimens [10,11], and validated IHC panels are now used clinically.Traditionally, pathologists have visually scored IHC data. For example, in the calculation of an HSCORE, a summation of the percentage of area stained at each intensity level mul

Abstract: in apple orchards, hail damage can be avoided by covering the plants with nets. however, the nets might change light intensity and quality supplied to the plants and, therefore, affect yield and quality of the fruit. this research was carried out to assess these aspects on 'fuji' apples trees uncovered and covered with white and black nets. the black net caused more substantial reduction of photosynthetic photons flux density (ppfd) available to the plants during the day (24.8%) than the white one (21.2%). the inner part of plants canopy covered by nets, especially under black net, received light with a lower red:far red ratio (r:fr), in comparison to uncovered plants. only under black net, the reductions of ppfd and r:fr of the light supplied to the plants increased the mean area and the specific area of the leaves and reduced the potential photosynthesis, leading to a reduction of yield (number and weight of fruits per cm-2 of trunk cross section area) and the red color of the fruit. the white and black hail protection nets reduced the incidence of sunburn but had no effect on russeting severity and number of seeds/fruit.

International Journal of Computer Technology and Applications , 2011,
Abstract: Steganography hides the very existence of a message so that if successful it generally attracts no suspicion at all. There are many techniques to perform steganography on electronic media, most notably audio and image files. In this paper, we present a new steganographic technique for embedding messages in BMP image. The main goal of this method, like any steganography techniques must do, is to hide a text of a secret message in the pixels of the image in such a manner that the human visual system is not able to distinguish between the original and the stegoimage, but it can be easily performed by a specialized reader machine. In this paper we are presenting the technique which works by changing a few pixel color value at specific points in the image. In a natural image, neighbor pixels have a high cross correlation. This point is alsotrue about LSB planes of close pixels. The points selected with mathematical operations based on image and considering the criteria of color intensity . Since the RGB image is composed of three colors, the image can be processed in three dimensions. So the pixels are more dispersed and security Image goes higher. It is also trying not to degrade image quality and information stored will not lose their security and as far as possible does not change the image size
