The data exhibited that when aragonite changed to calcite, its oxygen and carbon isotopic compositions dropped roughly on a linear trend. The linear trend implies that the oscillation pattern of the origin oxygen and carbon isotopic ratios of the aragonite could probably be retained after they diageneticly changed into calcite. Oxygen isotopic stratigraphy for the NY 1 core at the depth between 22 and 50 m was determined according to the δ 18 O ratios of the calcite coral. The oxygen stratigraphy provided an age of about 289 ka for 45 m of the NY 1 core, which agreed with that by paleomagnetic stratigraphy.展开更多

The method affords efficient separation and good linearity for each isomer in the range of 0.2 -200 μg/ml. The method can also be used in separation and determination of another thirty three aromatic and their halosubstituted compounds. This paper also presents the applications of the method in analysing of complex products mixture from reaction of the selected aromatic compounds with hydrogen chloride on fly ash surface from municipal incinerator.展开更多

Estimations of inclinations can be obtained from measurement of the Rossiter-McLaughlin effect, which is discussed using examples of some eccentric binaries with an anomalous apsidal effect. Our task is to find the complete spectrum of solutions of the equation of apsidal motion, depending on the inclinations of the polar axes of the components to the orbital one for these systems, based on their individual spectroscopic and photometric observational data. The matrix of solutions allows us to select those pairs of polar inclinations that provide agreement with the observational apsidal period.展开更多

This paper presents the pollen morphol- ogy of 20 species of tundra plants from the high Arctic of Ny-Alesund, Svalbard, using light and scanning electron microscopy. The plants used in this study belong to 12 families： Brassicaceae, Caryophyllaceae, Cyperaceae, Ericaceae, Juncaceae, Papav- eraceae, Poaceae, Polygonaceae, Ranunculaceae, Rosaceae, Salicaceae, and Scrophulariaceae. Pollen grain shapes included： spher- oidal, subprolate, and prolate. Variable apertural patterns ranged from 2-syncolpate, 3-colpate, 3-（-4）-colpate, 3-（-5）-colpate, 3-colporate, 5-poroid, ulcerate, ulcus to pantoporate. Exine ornamentations comprised psilate, striate-perforate, reticulate, mi- croechinate, microechinate-perforate, scabrate, granulate, and granulate-perforate. This study provided a useful reference for com- parative studies of fossil pollen and for the reconstruction of paleovegetation and paleoclimate in Svalbard region of Arctic.展开更多

Orange County, New York has been chosen for this study of Suboxone, a prescription medicine that is used to treat addiction to opioid analgesics. This drug is underutilized throughout Orange County because of several impediments, including insurance coverage, social stigmas, and a non-compliant patient population. Objective: The objective is to analyze the accessibility and utilization of Suboxone to treat opioid dependence in Orange County, New York. Method: Two survey instruments have been created for this research project, one for Suboxone providers and one for non-Suboxone providers. Each is 10 questions long, and includes multiple choice and open-response questions. Participants were contacted by means of email and telephone. Results: The results displayed that many Suboxone providers prefer not treating this patient population for the following reasons: insurance coverage problems, lack of time to see these demanding patients, and a non-compliant patient population. Almost all of the doctors surveyed believed that there is a social stigma among physicians to prescribe as well as among patients to use Suboxone. The non-Suboxone providers did not want to prescribe Suboxone because of a non-compliant patient population, and not having enough time in their practice. Almost all of the non-Suboxone providers prescribed other opiates. For most of the doctors, having more ancillary staff (psychologists, physical therapists, mid level providers) would motivate them to prescribe Suboxone. Discussion and Conclusion: Recommendations made by the local physicians for treating the current opioid epidemic include the following: more police enforcement of street drug dealers, patient education of narcotic misuse, physician education of both the opioid epidemic and patient treatment, and expanding access to rehabilitation and care for these patients.展开更多
