The formation of caves is the special environment of our earth. Caves with dim natural light and lighted hypogean environments, have been found various organism. The Kaklik Cave located tectonic lines and has a very different way of formation when compare with many other same karstic formation caves. The Kaklik Cave is located in the area of Kaklik town in Honaz area and in Denizli province. The cave is one of the 54 cave opened to tourism in Turkey and endanger. In this study the cave climate, hydrol?ogy and biology were studied. The cave has specific species due to this formation, the entrance is wide and open to the sky, that makes the sunlight could go through a very wide area and cause of it is very rich about hydrology, these effects;provide a very high biodiversity to the cave. The cave has very important touristic potential because of the continuously growing travertine, geographical position, availability of access and natural beauties. The wrong artificial lightning badly changes the natural structure of the cave. This artificial lightning causes the biofilm layer and changing on the color of the travertine.

Purpose: This study evaluated the influence of different storage times and storage solutions on the mineral content of enamel. Methods: Ninety enamel slabs were randomly divided into 2 groups of 45: a 45-day group and a 90-day group. Each of these main groups was further subdivided into 9 experimental groups of 5 slabs, and each subgroup was stored in a different storage solution. The mean percentage weights of 5 elements (calcium, potassium, sodium, phosphorus, and magnesium) presented in each enamel slab was measured after storage using inductively coupled plasmaatomic emission spectrometry. Two-way analysis of variance (ANOVA) and Turkey’s honestly significant difference tests were used to analyze differences between the groups. Results: Storage conditions significantly affected the levels of calcium, potassium, sodium, and phosphorus (p 0.05). Storage procedures can significantly affect the calcium, potassium, sodium, and phosphorus contents of enamel.

Objective: The aim of this study was to compare the effects of different surface treatments on the elemental composition stability of as-received and recast types of NiCr casting alloys. Material and Methods: Six commercial NiCr dental casting alloys (Kera N, Nodelco, Bellabond, Wiron 99, Metaplus VK, and Tritech D) were used in this study. Seventy-two specimens (12 × 12 × 1.2 mm) were produced using the lost-wax casting process. Three casting protocols were established in relation to the proportion of as-received and recast alloys: Group A (100% as-received metal), Group B (50 wt% new metal, 50 wt% once-recast metal), and Group C (100% once-recast metal). Two specimens in every group received two different surface treatments: sandblasting with 110 μmm Al2O3 or oxidation firing. An elemental analysis was performed with x-ray energy-dispersive spectroscopy. Results were subjected to one-way analysis of variance and Tukey HSD tests. Results: The elemental composition was significantly different in the casting groups and treatment groups (p < 0.05). The lowest mean weight percentage Ni value was recorded for Group C and the highest for Group A. Aluminum-oxide sandblasting of the alloy surface reduced the mean weight percentage for Cr. Conclusion: Recasting metal alloys may adversely affect surface quality.

Seed size and composition are important traits in food crops and can be affected by nutrient availability in the soil. Phosphorus （P） is a non-renewable, essential macronutrient, and P deficiency limits soybean （G1ycine max） yield and quality. To investigate the associations of seed traits in low- and high-P environ- ments, soybean recombinant inbred lines （RILs） from a cross of cultivars Fiskeby III and Mandarin （Ottawa） were grown under contrasting P availability environments. Traits including individual seed weight, seed number, and intact mature pod weight were significantly affected by soil P levels and showed transgressive segregation among the RILs. Surprisingly, P treatments did not affect seed composition or weight, suggesting that soybeanmaintains sufficient P in seeds even in Iow-P soil. Quantitative trait loci （QTLs） were detected for seed weight, intact pods, seed volume, and seed protein, with five significant QTLs identified in Iow-P environments and one significant QTL found in the optimaI-P environment. Broad-sense heritability estimates were 0.78 （individual seed weight）, *** （seed protein）, 0.34 （seed oil）, and 0.98 （seed number）. The QTLs identified under low P point to genetic regions that may be useful to improve soybean performance under limiting P conditions.

In this study, we consider the problem of scheduling a set of jobs with sequence-dependent setup times on a set of parallel production cells. The objective of this study is to minimize the total completion time. We note that total customer demands for each type should be satisfied, and total required production time in each cell cannot exceed the capacity of the cell. This problem is formulated as an integer programming model and an interface is designed to provide integrity between data and software. Mathematical model is tested by both randomly generated data set and real-world data set from a factory that produce automotive components. As a result of this study, the solution which gives the best alternative production schedule is obtained.

The aim of this study was to compare the effects of different porcelain polishing techniques on the color change and surface roughness of feldspathic porcelains and lithium disilicate glass-ceramic system. 80 porcelain specimens were divided into two subgroups, each subgroup was divided into 4 groups of 10 specimens. Surfaces were polished with different ceramic polishers. VITA Easyshade spectrophotometer was used to measure color differences. Surface roughness was evaluated using a profilometer. The color change and surface roughness of porcelains were statistically analyzed by Two-way ANOVA followed by a Tukey HSD test (α = 05). There were relationships between the porcelain systems and polishing techniques (p 0.05). For △E values, there was relationship between the porcelain systems and polishing techniques (p 0.05). Chairside porcelain polishing systems were not able to provide a porcelain surface as smooth as the glazed surface for the IPS empress and Ceramco 3 porcelains.
