Синтез и свойства реагентов на основе иодзамещенных гидроксиполиэтил бензоатов

Поиск новых органических производных иода и изучение препаративных возможностей данных соединений в окислительных процессах позволит ввести в практику органического синтеза новые реагенты для окисления. В результате работы получены новые соединения - иодзамещенные гидроксиполиэтил бензоаты. При окислении данных соединений будут получены водорастворимые соединения поливалентного иода, которые в свою очередь должны проявить свойства мягких окислителей в окислительных превращениях спиртов. Таким образом, становится актуальным синтез и изучение препаративных возможностей легко извлекаемых реагентов с требуемой окислительной активностью.The search for new organic derivatives of iodine and the study of the preparative capabilities of these compounds in oxidative processes will make it possible to introduce new reagents for oxidation into the practice of organic synthesis. As a result of the work, new compounds — iodosubstituted hydroxypolyethyl benzoates — were obtained. During the oxidation of these compounds, water-soluble compounds of polyvalent iodine will be obtained, which in turn should exhibit the properties of soft oxidizing agents in the oxidative transformations of alcohols. Thus, the synthesis and study of the preparative capabilities of easily recoverable reagents with the required oxidative activity becomes relevant

Site evaluation, design, operation, and installation of home sewage systems in Iowa

The demand for on-site waste treatment systems for dwellings not served by sewer systems continues to grow in Iowa. On-site systems, when properly designed and maintained, provide a viable means of treating septic tank effluent. A research project was initiated at Iowa State University to provide information for solving problems associated with design, location, and maintenance of on-site systems in Iowa. This publication is designed to report the results of the interdisciplinary research and provide information for sanitarians, extension personnel, and contractors on waste treatment systems.https://lib.dr.iastate.edu/specialreports/1083/thumbnail.jp

Gastrin-releasing peptide receptor-based targeting using bombesin analogues is superior to metabolism-based targeting using choline for in vivo imaging of human prostate cancer xenografts

Purpose: Prostate cancer (PC) is a major health problem. Overexpression of the gastrin-releasing peptide receptor (GRPR) in PC, but not in the hyperplastic prostate, provides a promising target for staging and monitoring of PC. Based on the assumption that cancer cells have increased metabolic activity, metabolism-based tracers are also being used for PC imaging. We compared GRPR-based targeting using the68Ga-labelled bombesin analogue AMBA with metabolism-based tar

The contribution of metacognitions and attentional control to decisional procrastination

Earlier research has implicated metacognitions and attentional control in procrastination and self-regulatory failure. This study tested several hypotheses: (1) that metacognitions would be positively correlated with decisional procrastination; (2) that attentional control would be negatively correlated with decisional procrastination; (3) that metacognitions would be negatively correlated with attentional control; and (4) that metacognitions and attentional control would predict decisional procrastination when controlling for negative affect. One hundred and twenty-nine participants completed the Depression Anxiety Stress Scale 21, the Meta-Cognitions Questionnaire 30, the Attentional Control Scale, and the Decisional Procrastination Scale. Significant relationships were found between all three attentional control factors (focusing, shifting, and flexible control of thought) and two metacognitions factors (negative beliefs concerning thoughts about uncontrollability and danger, and cognitive confidence). Results also revealed that decisional procrastination was significantly associated with negative affect, all measured metacognitions factors, and all attentional control factors. In the final step of a hierarchical regression analysis only stress, cognitive confidence, and attention shifting were independent predictors of decisional procrastination. Overall these findings support the hypotheses and are consistent with the Self-Regulatory Executive Function model of psychological dysfunction. The implications of these findings are discussed

The Open Innovation in Science research field: a collaborative conceptualisation approach

Openness and collaboration in scientific research are attracting increasing attention from scholars and practitioners alike. However, a common understanding of these phenomena is hindered by disciplinary boundaries and disconnected research streams. We link dispersed knowledge on Open Innovation, Open Science, and related concepts such as Responsible Research and Innovation by proposing a unifying Open Innovation in Science (OIS) Research Framework. This framework captures the antecedents, contingencies, and consequences of open and collaborative practices along the entire process of generating and disseminating scientific insights and translating them into innovation. Moreover, it elucidates individual-, team-, organisation-, field-, and society‐level factors shaping OIS practices. To conceptualise the framework, we employed a collaborative approach involving 47 scholars from multiple disciplines, highlighting both tensions and commonalities between existing approaches. The OIS Research Framework thus serves as a basis for future research, informs policy discussions, and provides guidance to scientists and practitioners
