Experimental investigation of subsurface damage depth of lapped optics by fluorescent method

Subsurface defects were fluorescently tagged with nanoscale quantum dots and scanned layer by layer using confocal fluorescence microscopy to obtain images at various depths. Subsurface damage depths of fused silica optics were characterized quantitatively by changes in the fluorescence intensity of feature points. The fluorescence intensity vs scan depth revealed that the maximum fluorescence intensity decreases sharply when the scan depth exceeds a critical value. The subsurface damage depth could be determined by the actual embedded depth of the quantum dots. Taper polishing and magnetorheological finishing were performed under the same conditions to verify the effectiveness of the nondestructive fluorescence method. The results indicated that the quantum dots effectively tagged subsurface defects of fused-silica optics, and that the nondestructive detection method could effectively evaluate subsurface damage depths.

Polymorphisms of alcohol dehydrogenase-2 and aldehyde dehydrogenase-2 and esophageal cancer risk in Southeast Chinese males

AIM： To evaluate the impact of alcohol dehydrogenase-2 （ADH2） and aldehyde dehydrogenase-2 （ALDH2） polymorphisms on esophageal cancer susceptibility in Southeast Chinese males.METHODS： Two hundred and twenty-one esophageal cancer patients and 292 healthy controls from Taixing city in Jiangsu Province were enrolled in this study. ADH2 and ALDH2 genotypes were examined by polymerase chain reaction and denaturing high-performance liquid chromatography. Unconditional logistic regression was used to calculate the odds ratios （OR） and 95% confidence interval （CI）.RESULTS： The ADH G allele carriers were more susceptible to esophageal cancer, but no association was found between ADH2 genotypes and risk of esophageal cancer when disregarding alcohol drinking status. Regardless of ADH2 genotype, ALDH2G/A or A/A carriers had significantly increased risk of developing esophageal cancer, with homozygous individuals showing higher esophageal cancer risk than those who were heterozygous. A significant interaction between ALDH2 and drinking was detected regarding esophageal cancer risk; the OR was 3.05 （95% CI： 2.49-6.25）. Compared with non-drinkers carrying both ALDH2 G/G and ADH2 A/A, drinkers carrying both ALDH2 A allele and ADH2 G allele showed a significantly higher risk of developing esophageal cancer （OR = 8.36, 95% CI： 2.98-23.46）.CONCLUSION： Both ADH2 G allele and ALDH2 A allele significantly increase the risk of esophageal cancer development in Southeast Chinese males. ALDH2 A allele significantly increases the risk of esophageal cancer development especially in alcohol drinkers. Alcohol drinkers carrying both ADH2 G allele and ALDH2 A allele have a higher risk of developing esophageal cancer.

New Method for Desalination of Seawater

The present study explores the possibility of appealing to the laws of inorganic chemistry, i.e., the rules of precipitation to desalinate seawater. Historically, the industry has been using these techniques for the preparation of some compounds. Based on these rules, using suitable salts will react with each other. The results are evident all unwanted salts including sodium chloride are removed. In fact, it is a selective precipitation as other salts which are not harmful are kept such as potassium. The other aim of the study is to reduce the current ratio desalination/power which is very high 60,000 to 80,000 cal/L for distillation （A. Payant. P. Chiliotti L. Sainte-Marie Physic Arm and Colin, Paris, France） or 4.5 kWh/m3 for RO （desalination and water reuse, California, USA） a cause of greenhouse gas except desalination using solar energy. Another aspect of this study, authors noticed rather than consume energy, regeneration or recycling of products provides energy. And in addition, the operation does not cause any pollution.

Seasonal Effect on Atmospheric Refractivity in Diverse Terrains

Air masses in the atmosphere have contrasting temperature, humidity and moisture, which influence radio signals traversing the atmosphere. The influence of the atmosphere on refractivity is strongly determined by its temporal and spatial variability. This paper uses meteorological measurements to investigate the impact of meteorological structures on diverse environments evident in Nigeria. The study hypothesises that refractivity measures could serve as indicators of diurnal radio wave degradation traversing the atmosphere.

Mechanistic Classification of Cement Treated Base in Western Australia

In the past decade alone, the BITRE has indicated an increase of 40% in road users, escalating demands for quality pavements to service tmprecedented traffic conditions. An abundance of crushed rocks are available in Western Australia but do not meet strength requirements for road construction. However, cement treatment of crushed rocks, forming Cement Treated Crushed Rocks （CTCR）, improves the mechanical properties of the material, allowing wider application. In order to streamline the mix design of CTCR, the classification of its behaviour is pivotal. Austroad classifies cement treated pavement materials as either being modified or bound based on its Unconfined Compressive Strength （UCS） and performance attributes. Bound materials are def＇med by its susceptibility to fatigue failure which, in the mechanistic-empirical design for flexible pavements, is dictated by the flexural modulus. However, in the study of damage mechanics, fatigue life is suggested to be an accumulation of micro-scale damage in lieu of dependency to ultimate stresses. Strain dependent damage functions are used phenomologically to explain the evolution of fatigue for various engineering materials. This paper therefore investigates a theoretical relationship between strain and fatigue life prediction supported by a laboratory investigation on the use of UCS for classification. This is achieved by providing regression analysis with strain parameters used in fatigue life prediction. The Indirect Tensile Strength （ITS） test is also employed to this end. It is observed that strain at onset of micro-cracking coalescence （ε30） is independent of test type undertaken and potentially capable of acting as a more superior blanket classification for cemented materials.

Data Regarding Qualitative and Quantitative Composition of Benthic Populations from Musura Bay-Danube Delta, Romania

The present paper refers to some data regarding zoobenthic communities from one of northern lagoon of the Danube delta, known as Musura bay （ROSCI0065, coded as coastal lagoon ＊ 1150）. Faunal composition is influenced by the mixture of waters from the Danube and the marine coastal zone. According to monitored areas, there are dominant freshwater or marine invertebrates forming populations that live in the sediments. The aim of this paper is to offer a view of the endopsammic and endopelitic benthic communities from Musura bay, during two years of observations （2013 and 2014） and analyze the seasonal dynamics of invertebrates＇ populations. Based on quantitative samples collected from infralittoral zone, the paper presents the qualitative structure and a quantitative analyze （abundance, constancy--F%, dominance--D% and Wo%） of invertebrate populations from all taxa （belonging to Foraminifera, Nematoda, Gasteropoda, Oligochaeta, Polychaeta, Ostracoda, Copepoda, Cumacea, Amphipoda and Chironomidae etc.） found in the researched zones, in connection with variation of local ecological conditions. Some considerations regarding the role of invertebrates＇ populations as food resources for lagoon fishes are done,

The paper summarizes the application, including system aspects that require special control functions in the SVC （static var compensator） regulator. Several important benefits for the system operation are demonstrated, such as increased power transmission import over an existing 230 kV network, dynamic bus voltage stabilization for various load conditions, including system outages and load rejection, and reduction of variable speed drive shutdowns by up to 95%. Some relevant design features of the SVC are treated, as well.

DYNAMIC CHANGES OF INORGANIC NITROGEN AND ASTAXANTHIN ACCUMULATION IN HAEMATOCOCCUS PLUVIALIS

This study on dynamic changes of culture color, astaxanthin and chlorophylls, inorganic N including N NO - 3, N NO - 2 and N NH + 4 in batch culture of Haematococcus pluvialis exposed to different additive nitrate concentration showed (1) ast/chl ratio was over 0.8 for brown and red algae, but was usually less than 0.5 for green and yellow algae; (2) N NO - 3, in general, was unstable and decreased, except for a small unexpected increase in nitrate enriched treatment groups; (3) measurable amounts of N NO - 2 and N NH + 4 were observed respectively with three change modes although no external nitrite and ammonia were added into the culture; (4) a non linear correlation between ast/chl ratio (or color) changes and the levels of N NO - 3 , N NO - 2 , N NH + 4 in H. pluvialis culture; (5) up and down variation of the ast/chl ratio occurred simultaneously with a perceptible color change from yellow to brown (or red) when N NO - 3, N NO - 2 and N NH + 4 fluctuated around 30, 5, 5 μmol/L respectively; (6) existence of three dynamic modes of N NO - 3, N NO - 2 and N NH + 4 changes, obviously associated with initial external nitrate; (7) the key level of total inorganic N concentration regulating the above physiological changes during indoor cultivation was about 50 μmol/L; and (8) 0.5-10 mmol/L of nitrate was theoretically conducive to cell growth in batch culture.

Radio Soccer Commentary as Reconstruction and Performance of Political and Social-cultural Reality： The Case of Kenya in the 1980s

This paper has developed the argument that live radio soccer commentary （LRSC） is a representation of soccer match events at one level but a performance of dominant socio-cultural and political trends of the societies at another level that produce and consume them. This echoes Reaser＇s （2003） and Ryan＇s （1993） perceptions of sports announcer＇s talk as a complex performance form based on but not limited to the ＂verbal imitation＂ of live sport events. We have understood the performativity of the LRSCs in the light of Schechner＇s （2006） emphasis of what he termed ＂restored behaviour＂ in understanding performance. In our context, we have treated the interpenetration of Kenyan soccer, politics, and society as the ＂restored behaviour＂ upon which the script of the LRSCs are based. The methodological apparatus of this paper is largely qualitative, consisting in the critical analysis of audio-recordings of Kenyan LRSCs. Focus is made on the Kenyan society of the 1980s, an era perceived to have been characterized by a close interaction between soccer, society, and politics. The analysis is informed by Fabian＇s （1997） inter-textual approach to the ＂reading＂ and interpretation of performance texts. This approach seems to echo a wider discourse of the social nature of media-text interpretation that has been proposed by Burn and Parker （1985）. Conclusions drawn from the analysis reveal what Muponde and Zegeye （2011） had described as a soccer ＂ecosystem＂ involving soccer as a sport, and the socio-cultural realities of its immediate context. This paper has argued thatLRSC is one of the channels through which this ecosystem is expressed.

Influence of Inorganic Salts during the Photooxidative Process of Nitrobenzene

Into the photooxidation process, several factors such as pH, time of irradiation, dose of UV light, lamp power, contaminant concentration, turbidity of the solution and the presence of salts can interfere with the photodegradation of pollutants. This research aims to evaluate the influence of salts： NaCl, MgCl2, CaCI2, BaC12, CuCl2, Na2SO4, MgSO4, MnSO4, FeSO4, CuSO4, Na3PO4, K2CrO4 and K2Cr207 in concentrations of 0.0005 M, 0.005 M and 0.05 M during photodegradation of aqueous solution of 59.5 mg/L of nitrobenzene at a pH of 2.5. It was observed that the presence of salts such as CuCI2, CuSO4, FeSO4, K2CrO4 and K2Cr207 interfere negatively in the system UV/H202 applied for degradation of nitrobenzene; possibly by oxidation of Fe2＋ to Fe3＋ and Cu＋ to Cu2＋ in the Cr case, due to the difficulty of transforming the Cr6＋ to Cr3＋ or because these solutions have color and act as radiation absorbing filter.

Accounting Aspects on Biotechnology and Their Products： According to Theory and Practice in Bulgaria

Biotechnology and the rights on biotechnological products are present-day topics, but at the same time, topics with deep historical roots. Biotechnological achievements are not a novelty to Bulgaria. They have existed for thousands of years and are connected with the production of milk and milk products, rose oil, herbal raw materials, and etc.. Contemporary biotechnological achievements are marketed in the form of nutritional, medicinal, and chemical products or as environmental protection. Traditional knowledge and achievements of modern science put the legal protection of biotechnology and its products on the agenda. In the national context, such rights have been statutory regulated and studied by specialists in the field of intellectual property. The problematic issues have not been so adequately treated in the country in terms of accounting theory and practice. The rights on biotechnology and biotechnological products are not within the scope of accounting items and accounting assets respectively. This is the motivation for the author to study the rights on biotechnology products within the context of their recognition as intangible assets. The author tries to present the conceptual framework for their identification and recognition as accounting items, as well as to define some scientific application problems on the topic.

Effect of Inorganic and Organic Based Fertilizers on Growth Performance of Tea and Cost Implications in Kusuku, Nigeria

A plot of 24 m × 10 m under fallow management after several years of cultivation to maize （Zea mays） was planted to tea （Camellia sinensis） cuttings at 1.0 m ×0.6 m and treated with or without fertilizer. The tea cuttings were applied NPK 25：5：5 （reference fertilizer）, cocoa husk, cow-dung, tea fluff and poultry droppings as manures, mixtures of the manures with urea in 3：1 ratio of N contents as organomineral and the control （no fertilizer）, monitored for growth performance for two years at Kusuku （6°50＇N; 11 °07＇E）, Nigeria. The organic based fertilizers generally outperformed NPK 25：5：5 and control in all the growth parameters. Organominerals resulted in an overall higher plant height, girth, number of leaves and branches compared to the manures in the first year of establishment, while the values were higher for manure treated plants in the second year. This trend was attributed to quicker release of nutrient by the organominerals in the first year, while the manures had undergone adequate decomposition for sufficient nutrient release to the advantage of the tea plants in the second year. However, comparative cost analysis showed that organominerals were more economical to achieve optimum tea production at minimum cost in the locality.

Karyological and morphometric variation of the North African green frog Pelophylax saharicus (Anura) in northeastern Africa

Morphometric variation ofPelophylax saharicus was analysed using univariate and multivariate statistics, with both traditional and geometric morphometrics, based on 148 specimens from four different geographical localities in Tunisia and Algeria. The results show the existence of three morphotypes in Tunisia and one in Algeria, and indicate a significant degree of variation in morphometric characters between regions. Specimens from the southernmost region have the smallest body size and the greatest morphometrie divergence from other populations. This pattern of morphometric variation probably results from phenotypic plasticity in response to local environmental factors. The results of our chromosomal study （C-, Ag-NOR-, endonuclease digestion, DAPI, CMA3 and Q-banding） reveal this species to exhibit the plesiomorphic Pelophylax karyotype of 2n=26 biarmed chromosomes and NORs on the eleventh pair. Similarities and differences of the North African green frog are discussed in relation to the different forms of data collected （chromosomal, morphometric, ecological） [Current Zoology 56 （6）： 678~586, 2010].
