Professional soccer goalkeepers performance: Study of goalkeeping performance with Nike Maxsight contact lenses

Background: Sun eyewear has been shown to have visual performance benefits. However, in fast moving ball sports, especially contact sports, sunglasses have limited applications. New contact lens technology has allowed the visual benefits of sun eyewear to be adapted into a frameless application ideal for contact sports. This study looked at the objective and subjective performance benefit of the Nike MaxSight contact lens (CL) for professional soccer goalkeepers. Methods: Fifteen goalkeepers (13 first time contact lens wearers) at the Professional Goalkeepers Camp in Alsagers, England, aged 18-41, practiced for one week wearing the Amber MaxSight CL and completed a subjective questionnaire. During that week, 9 goalkeepers participated in a controlled study of goalkeeping performance while wearing the MaxSight CLs compared to clear Optima 38 CLs. Each athlete defended the goal from a simulated obstructed-view free kick; the goal keeper acting as his own control. A subjective questionnaire was completed after participating in the study. Results: Goalkeeping performance was not enhanced while wearing MaxSight CLs compared to clear Optima 38 CLs (p\u3c0.21) under varying natural light conditions. Subjectively, athletes did report an improvement in visual comfort in varying weather conditions, a mean value of 4.46 (SE 0.13) in sunny conditions and 4.36 (SE 0.22) in overcast, rainy conditions on a 5-point scale of visual comfort. The goalkeepers preferred the MaxSight CL to the clear Optima 38 graded on the same 5 point visual comfort scale. While wearing the MaxSight CLs, the participants reported no distortions, physical discomfort, and improved ability to track the ball. Conclusions: There was no statistical difference in objective performance by the goalkeepers while wearing the Amber Maxsight CL compared to clear Optima 38 CL in varying weather conditions. There was a subjective difference in visual comfort while wearing the MaxSight SCL

Utilization of Biotechnology on Some Forest Trees in Turkey

Background and Purpose: Raw wood material requirements are increasing with rapid population growth both in Turkey and in the world. In order to supply deficit for closure of forest products, productivity and quality of production should be improved. Basic ways to increase efficiency in forest production involves silvicultural implementations and classical tree breeding studies. Genetic variation can be increased by utilizing the existing diversity. Thus, new combinations can be obtained and we can raise efficiency using some selection strategies. At this point, biotechnological methods are required to meet the genetic material. Studies of forest tree breeding are a slow process due to the size of the genome and the length of the tree life span. Biotechnological applications in forest trees provide many important benefits in terms of time saving and reducing cost when compared to classical breeding studies. Sustainable forestry practices are gaining rapid acceleration via biotechnology and modern sciences practices. In this study, for some forest tree species in Turkey, the evaluated biotechnology methods included; 1- tissue culture and clonal propagation, 2- molecular marker applications, 3- marker assisted selection and breeding, 4-genomic and proteomic studies, 5- genetic modification and genetic engineering applications. Conclusions: In this study, the works were carried out on forest tree breeding/propagation in Turkey and it was mainly focused on vegetative production techniques with 25 broadleaves and 9 conifer taxa, which were possible to express. Molecular genetic studies were carried out on 12 broad leaves taxa and 9 conifer taxa; genetic transformation studies were conducted on poplar species. Thus, it might be suggested that a combination of biotechnological tools and traditional propagation methods will ensure advantage for the development of forest-tree species

Dynamic Partnership in Online Logistics Community

Agents of various capabilities in the logistics community individually or together collaboratively serve very different shipment requests offline. With the challenges of global e-business, the capabilities of collaborative partnering and planning online increase agents’ competitiveness and enhance logistics process performance. In this paper, we define dynamic partnership – a conceptual underpinning to maximize the four e-rights for the online logistics community. Three core factors, namely credibility, reliability and viability are introduced to guide successful partnership online. A survey of logistics service providers in Hong Kong confirms the relevancy of the four e-rights and three core factors in collaboration efforts. A conceptual analysis with respect to partnership flexibility, collaboration and performance of dynamic partnership is given. To realize such partnership in the logistics community, the electronic platform requirements are identified

Age-Related Changes of Some Chemical Components in the Leaves of Oriental Beech (Fagus orientalis Lipsky.)

Background and Purpose: This study presents the analysis of photosynthetic pigments, proline, total soluble protein, total amino acids, glucose, sucrose, total soluble sugars, total amount of phenolic compounds and flavonoids, malondialdehyde (MDA) and hydrogen peroxide (H2O2) concentration in the leaf samples collected from oriental beech trees, which are naturally spread in Kastamonu Province, Turkey, with differing ages, enzyme activities of ascorbate peroxidase (APX), catalase (CAT) and superoxide dismutase (SOD). Material and Methods: The research was carried out on oriental beech trees (Fagus orientalis L.) of different ages located at 1300 m high elevation in Ahlat Village of Kastamonu Province, Turkey. Oriental beech trees of different ages (≥25, ≥50, ≥100, ≥200 and ≥600 years-old) constituted the material of this study. In leaf samples taken from trees of different ages, photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophyll and carotenoid), proline, total soluble protein, total amino acid, glucose, sucrose, total soluble sugars, the amount of total phenolic compounds and flavonoids, MDA, H2O2 concentration, enzyme activities of APX, CAT and SOD, as well as the relationship between the total content of C, N and H elements and the tree ages were studied. Results: As a result of the research conducted, significant differences were determined in terms of chlorophyll, total phenolic compound, flavonoid, glucose, amounts of sucrose, nitrogenous compounds, proline, total soluble protein, MDA, H2O2 concentrations, and the activities of APX, CAT and SOD in the leaves of oriental beech trees with differing ages. The highest content of chlorophyll a was found to be in the youngest age group of ≥25 years. Total chlorophyll is low in young trees and high in middle-aged, old and very old trees. According to the results obtained, it was concluded that the MDA and H2O2 concentrations in the trees did not vary depending on the age of trees only, but also on the genotype, environmental conditions and metabolic activities. It was concluded that the fact that the total chlorophyll, phenolic compounds and sucrose content in oriental beech trees are high and that MDA content is low could have an influence on the long life of ≥600 years-old oriental beech trees. Conclusions: The activity of photosynthesis is related to leaf characteristics more than the age of trees

MICROFOULING ON CATHODICALLY PROTECTED MILD STEEL IN SEA WATER

ABSTRACT The influence of cathodic protection on the rate of microfooling on mild steel was investigated in natural seawater. Cathodic protection was applied at current densities of 0.12 and 0.22 mA/cm2 using sacrificial zinc anodes. The rate of attachment of bacteria and diatoms was observed to increase dramatically as a function of applied current, particularly during the first few days of exposure. It was also found that sulphate-reducing bacteria come into the scene as early as the fourth day white freely corroding specimens encourage SRB activity only by the twelfth day of exposure. The growth rate of calcareous depos~ts was also investigated to make it comparable with that of microorganisms

Toros sediri (Cedrus libani A. Rich.), Türkiye’de Anadolu karaçamından (Pinus nigra Arnold. subsp. pallasiana Lamb. Holmboe) sonra ağaçlandırma çalışmalarında en çok tercih edilen, plastitesi yüksek bir türdür. Potansiyel ağaçlandırma çalışmalarına katkı sağlamak ve Türkiye’de mevcut Toros sediri ağaçlandırma sahalarının tespiti için; türün dijital yayılış haritası baz alınarak ArcGIS programı ve Orman Genel Müdürlüğü Ağaçlandırma Daire Başkanlığı dokümanları kullanılmıştır. Çalışma sonucunda; 15 Orman Bölge Müdürlüğünde 26 işletme müdürlüğü bünyesinde ve takriben 85 işletme şefliğinde/lokalitede Toros sediri ağaçlandırmalarının varlığı tespit edilmiştir. Ağaçlandırma projelerinde uygulama amaçları genel olarak; “Erozyon Kontrol, Ağaçlandırma, Toprak Koruma, Sosyal Ormancılık, Karayolu Kenarı Ağaçlandırması, Yeşil Kuşak Ağaçlandırması ve Çevreyolu Ağaçlandırması” olarak belirlenmiştir. Mevcut ağaçlandırma sahaları De Martonne, Erinç ve Aydeniz iklim sınıflandırmalarına göre irdelendiğinde; De Martonne göre; Yöntemin belirlediği 8 iklim indisinden "Step-nemli arası", "Yarı nemli" ve "Step-yarı kurak" olan üç iklim tipinde Toros sediri plantasyonları görebilmektedir. Erinç’e göre; "Nemli", "Yarı nemli" ve "Step-yarı kurak" iklim tipleri; Aydeniz’e göre ise belirlenen 7 iklim sınıflandırmasından "Kurak", "Yarı kurak", “Nemli” ve "Yarı nemli" iklim tiplerinin Toros sediri plantasyon alanlarında hakim olduğu belirlenmiştir. İndis değerleri bakımından Toros sediri plantasyon sahaları incelendiğinde; De Martonne kuraklık indisinin (Ia) 9.10 ile 20.53; Erinç yağış etkenlik indisinin (Im) 18.42 ile 44.45 ve Aydeniz kuraklık katsayısının (Kks) 0.43 ile 1.48 arasında değer aldığı hesaplanmıştır. Bu değerlere göre Toros sedirinin iklim amplitutesinin geniş olduğu teyit edilmiştir.In Turkey, Taurus cedar (Cedrus libani A. Rich.) is the most preferred species in afforestation practices after Anatolian black pine (Pinus nigra Arnold. subsp. pallasiana Lamb. Holmboe); also it has highest plasticity. For the determination of the existing Taurus cedar plantation areas in Turkey and to contribute to potential afforestation work; based on the digital distribution map of the species, the ArcGIS program and Forestry General Directorate Afforestation Department of documents were used. In the results of the study; the existence of Taurus cedar plantation was determined in the 15 Regional Directorates of Forestry, 26 forest management directorate and approximately 85 forest district/location. The purposes of the plantation projects are generally defined as Erosion Control, Afforestation & Soil Conservation, Social Forestry, Roadside Planting, Green Belt Afforestation and Belt Highway Afforestation. The current plantation areas according to climate classification of De Martonne, Erinç and Aydeniz have been analyzed. According to De Martonne; Taurus cedar plantations can be seen in the three climatic types "Step-humid", "Semi-humid" and "Step-semi arid" from 8 climatic indices. "Humid", "Semi-humid", and "Step-semi arid" climate types were identified by Erinç. According to Aydeniz, four climatic classes were identified from 7 types of climates: "Arid", "Semi-arid", “Humid” and "Semi humid". When the Taurus cedar plantations are examined in terms of their index values; De Martonne drought index (Ia) from 9.10 to 20.53; The precipitation efficiency index (Im) of Erinç were between 18.42 and 44.45 and the Aydeniz drought coefficient (Kks) between 0.43 and 1.48 were calculated. According to these values, it has been confirmed that Taurus cedar has a wide range of climate amplitudes

Lead exposure in adult males in urban Transvaal Province, South Africa during the apartheid era

Human exposure to lead is a substantial public health hazard worldwide and is particularly problematic in the Republic of South Africa given the country’s late cessation of leaded petrol. Lead exposure is associated with a number of serious health issues and diseases including developmental and cognitive deficiency, hypertension and heart disease. Understanding the distribution of lifetime lead burden within a given population is critical for reducing exposure rates. Femoral bone from 101 deceased adult males living in urban Transvaal Province (now Gauteng Province), South Africa between 1960 and 1998 were analyzed for lead concentration by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Of the 72 black and 29 white individuals sampled, chronic lead exposure was apparent in nearly all individuals. White males showed significantly higher median bone lead concentration (ME = 10.04 µg·g−1), than black males (ME = 3.80 µg·g−1) despite higher socioeconomic status. Bone lead concentration covaries significantly, though weakly, with individual age. There was no significant temporal trend in bone lead concentration. These results indicate that long-term low to moderate lead exposure is the historical norm among South African males. Unexpectedly, this research indicates that white males in the sample population were more highly exposed to lead
