Abstract: An accurate formulation to predict the thermal post-buckling load carrying capacity of orthotropic circular plates based on von Kàrmàn nonlinearities is reported in this paper. The governing differential equations of circular plates with orthotropic material properties are converted into linear differential equations employing the nondimensional parameters. The radial edge load is evaluated by assuming suitable admissible functions for the lateral displacement. Simply supported and clamped boundary conditions are considered in this study. The Rayleigh - Ritz method of total potential energy gives the values of linear buckling load. The thermal postbuckling load of orthotropic circular plates is evaluated using the radial edge load and linear buckling load. The influences of suitable admissible functions on the lateral displacement are also discussed. The numerical results obtained from the present investigation are compared with the known results reported in the literature and are in good agreement within the engineering accuracy. The error percentage of the results has been predicted and a maximum error is found out to be 4.02 % for simply supported and 3.67 % for clamped boundary conditions respectively.

Abstract: This study was carried out to determine the possibilities of vegetative propagation of the widespread 5 Rhododendron species (R. ponticum L, R. luteum Sweet, R. smirnovii Trautv, R.ungernii Trautv, and R. caucasicum Pallas) in Turkey. The plant material was obtained as shoot tip cuttings from Black Sea Region flora at three times (June, July and August). The respective cutting materials were subjected to 5 Indole-3-butryic acid (IBA) doses (0, 4000, 8000, 12000 and 16000 ppm) and planted in acidic peat and perlite mixture under mist propagation in greenhouse condition. Sixty cuttings (20 cuttings with 3 replicates) were used for each treatment. Totally, 300 cuttings were used. Results showed that three rhododendron species (R. ponticum, R. luteum and R. smirnovii) were successfully rooted but the others (R. ungerni and R. caucasicum) were not. Only 16.000 ppm IBA gave the highest rooting rate (46.67%). The highest rooting rates were obtained in R. ponticum as 46.66 % from August cuttings, in R. luteum as 38.33 % from June cuttings and R. smirnovii as13.33% from August cuttings. To conclude, when the cutting materials were obtained in summer season, their rooting rates were quite low in Rhododendron species, suggesting that when it is difficult to reach these plants in heavy winter conditions, it can be worked on summer cuttings even low rate of rooting.

Abstract: In this study, it was aimed to determine certain microbiological characteristics, mineral contents heavy metal levels in 16 Aho cheeses of Sürmene and Araklı districts of Trabzon and to determine the suitability of the Turkish Food Codex. Mineral ingredient and heavy component contents have been identified based on ICP-OES implementation and in mg kg-1 unit type. In Aho cheese samples the average levels of the mineral contents and heavy metals in the Aho cheeses were determined as; calcium 3628.30±355.07 mg kg-1, potassium 461.20±33.48 mg kg-1, sodium 8463.75±658.97 mg kg-1, magnesium 163.42±10.96 mg kg-1, iron 5.46±1.29 mg kg-1, zinc 27.04±2.62 mg kg-1, copper 1.358±0.13 mg kg-1, manganese 0.31±0.17 mg kg-1, phosphorus 4187.05±327.60 mg kg-1, lead 0.174±0.04 mg kg-1 and cadmium 0.028±0.04 mg kg-1.

As a result, it was determined that the mineral contents and heavy metal levels of the cheese samples were within the limits determined by the Turkish Food Codex for some foods.

Abstract: The Karayaka sheep is the most populous sheep breed in the Black Sea region of Turkey and a significant portion of the breed (30-35%) has been raised for centuries in Samsun province. For this reason, we aimed to investigate the genetic diversity of Karayaka sheep raised in Samsun, Turkey. The blood samples used in this study were collected from unrelated animals and were analysed using nine microsatellite markers. A total of 72 alleles were determined with an average of eight alleles per locus. The highest number of alleles (12) was observed for locus BM1314, while the lowest (4) was observed for locus CSSM47. The expected heterozygosity value (He) ranged from 0.654 at locus BM757 to 0.867 at locus BM1314, with an average of 0.757, whereas the observed heterozygosity (Ho) ranged from 0.125 at locus CSSM47 to 0.438 at locus BM757 and HUJ616, with an average of 0.329. The Wright’s fixation index (FIS) values ranged from 0.360 at locus BM757 to 0.833 at locus OARFCB304, with an average of 0.572. The results obtained from this study showed that Karayaka sheep population has a high level of genetic diversity and the studied markers were highly informative.

Abstract: In this study, the physico-chemical properties of hot spring water of Bursa province and Erikli cold water were investigated. Erikli cold water is bottled for commercial use. Water samples were collected in-situ for testing and some physical measurements were carried out. Other major analyses were carried out in the geothermal laboratory. Water samples were evaluated by both field observations in-situ and also geological and petrographical observations. Data collected were evaluated by using Aqua-Chem software program in consideration of field observations and the geology and petrography of the sampling area. Data obtained from Aqua-Chem and field observations of the sampling area in consideration of geology and petrography were used for interpretations of hot water samples and cold spring water. Consequently, water samples were characterized according to sources of magma or meteoric waters with the aid of isotope studies and cation and anion data. Also, information on water circulation leading to water-rock interaction where the water passes the Bursa Geothermal system helped the interpretation. The water sample radioactivity results were shown to be within acceptable limits. Water resources were determined for Bursa province and vicinity using Piper diagram. Waters in Cekirge, Kaynarca, Kükürtlü, Zeynine, Dumbuldek, and Inegol Oylat contain Ca-Mg-Na-SO4, Na-Ca-SO4, Na-Ca-HCO3-SO4, Ca-Na-Mg-SO4, Na-Ca, Ca-SO4-HCO3 ions respectively.

Abstract: The world suffers from air pollution from burning fossil fuels to produce energy. Cars consume a large proportion of fuel, especially spark ignition engines. The pollutants produced by these engines can be reduced using new types of alternative fuels, including hydrogen gas. Hydrogen is characterized by its high speed and high resistance to knock, making it an acceptable option for use in spark ignition engines. Among the disadvantages that prevent the use of hydrogen is its ease of ignition, safety requirements, lack of energy on the volume basis. In this study, we are trying to review a number of new researches which have tested practically and theoretically the use of hydrogen in ignition engines.

Abstract: The present study was conducted with the aim to investigate, antifungal activities in vitro conditions of the essential oil retrieved from laurel (Laurus nobilis) and myrtle (Myrtus communis L.) on three different isolates of the chickpea blight disease (Ascochyta rabiei). The antifungal activity study was conducted in 60 mm in diameter petris with 10 ml PDA environment, and the plantation of fungi was done in the middle of the petri in a diameter of 5 mm.

The study tries to understand the antecedents of consumer preferences towards online and offline shopping. A conceptual model that addresses consumer value perception for using the internet shopping versus the traditional shopping. Earlier studies have shown that perceptions of price, product quality, service quality and threat strongly impact perceived value and purchase intents in the offline and online network. Observations of online and offline buyers can be evaluated to see how value is constructed in both channels. The objective of this study is to provide an impression of online shopping decision process by comparing the offline and online decision making and identifying the factors that motivate customers to decide whether to do online shopping or go for the offlin e shopping. Consumer’s shop when and where they want, where they are comfortable with the products and the choice of shopping. The study finds that female are more into online shopping than male. Since last two years as population are more aware of the technology the online shopping increased immensely. The people from the age group 35 and above are less likely to do online shopping because they are less aware of the technology. However the respondent said that they will love to purchase from online shopping if only the price of the product is less than the market. They revealed that it is fairly important to go for e-shopping.

Good customer service is the lifeblood of any business. You can offer promotions and slash prices to bring in as many new customers as you want, but unless you can get some of those customers to come back, your business won't be profitable for long.Good customer service is all about bringing customers back. And about sending them away happy - happy enough to pass positive feedback about your business along to others, who may then try the product or service you offer for themselves and in their turn become repeat customers. If you're a good salesperson, you can sell anything to anyone once. But it will be your approach to customer service that determines whether or not you’ll ever be able to sell that person anything else. The essence of good customer service is forming a relationship with customers – a relationship that that individual customer feels that he would like to pursue. How do you go about forming such a relationship? By remembering the one true secret of good customer service and acting accordingly; "You will be judged by what you do, not what you say. “I know this verges on the kind of statement that's often seen on a sampler, but providing good customer service IS a simple thing. If you truly want to have good customer service, all you have to do is ensure that your business consistently does the right thing for its customers.

To assess the distribution and severity of tooth wear among adult population of Andhra Pradesh. A descriptive cross sectional study was conducted by trained and calibrated examiner. A stratified random sample of 1611 individuals with the age of 35-44 years were examined for tooth wear using Smith and Knight tooth wear index (1984). Descriptive statistics were applied to the data. Prevalence of tooth wear amounted to 70.62%. The highest frequency of score 1 was found for mandibular right 1st molar (41.6%) and score 2 for maxillary left central incisor (20.8%), score 3 for mandibular left 1st molar (6.3%) and score 4 for mandibular left 2nd premolar (7.3%). Occlusal surfaces were most commonly affected with tooth wear when compared to buccal, lingual and cervical surfaces. It also shows that occlusal surfaces of maxillary and mandibular anterior teeth were more commonly affected than the posterior teeth. No tooth wears on the lingual surfaces of posterior teeth of both the arches. Tooth wear remains a common finding in study population. Furthermore, the question of whether tooth wear is a public health problem remains open for debate.

Almost 80% of the world’s visual impairment is treatable or preventable. Regardless of this, millions of people are at risk of visual loss due to the lack of eye-care services. The study examined eye care needs of persons with visual impairments in a District Hospital in Ghana, specifically to assess the availability of eye care services, challenges and measures to improve accessibility. A qualitative approach was adopted to interview persons with visual impairments and eye care providers. Purposive sampling was used to select a sample size of 20; 15 visually impaired and 5 health care providers. A semi-structured interview guide was adopted to capture data onto a voice recorder and transcribed into written notes. Thematic content analysis was used to analyse themes generated from the data according to the objectives. The study found that eye care services were available to some extent but accessibility to the services was limited due to inadequate transport fares and poor health insurance coverage. Aids to accompany clients were limited. Poor infrastructure and equipment limited the ability of healthcare providers to offer effective services. The study recommends that outreach services should be encouraged to provide services at the doorstep to majority and refer complex cases to hospital to reduce cost of transportation. The study further recommends that relevant infrastructure and equipment should be provided by government through the Ghana Blind Union to improve eye care services and also to ensure that health insurance policies adequately cover diagnosis, treatment and the provision of assistive devices.
