Development and Preclinical Evaluation of Preparation Effectiveness for the Treatment of Hard Tooth Tissues after Temporary Filling Removal

The purpose of this study was development and preclinical study of the effectiveness of antiseptic liquid for the purification of dentinal tubules. Liquid application is planned after extraction from the prepared carious cavity of a temporary filling. According to the recommendations of clinicians, liquid should be sufficiently flowable to penetrate the lumen of the dentinal tubules and wash out fragments of temporary filling materials. At the same time, having an antiseptic effect, it should not change the strength characteristics of tooth hard tissue

ПОВЫШЕНИЕ ДОСТОВЕРНОСТИ ОЦЕНКИ ВАЛОВОГО РЕГИОНАЛЬНОГО ПРОДУКТА ПРИ ПОСТРОЕНИИ ПРОГНОЗОВ РАЗВИТИЯ РЕГИОНА

The article describes the role of the gross regional product (GRP) in the scenario forecasting of regional economy development using the pilot region - Sakha (Yakutia) Republic - as an example. The special attention is paid to the compatibility of statistical information obtained at the federal and regional levels in order to ensure the consistency of relevant forecasts. The scope and direction of gross regional product changes were estimated with regard to the transition to new GRP methodology due to the recalculations of the System of National Accounts (SNA) indicators for 2011-2014 at the federal level launched by the Federal State Statistics Service (Rosstat) in 2015. The results of the experimental correction of GRP according to the new methodology, which are necessary for the forecast of the Republic of Sakha (Yakutia) socio-economic development for the period of up to 2035 in accordance with the scenarios - basic, conservative and targetoriented, - are presented. The recalculation of the Sakha (Yakutia) Republic' GRP physical volume dynamics under each scenario has been made taking into account the expected methodological changes. В статье отражена роль показателя валового регионального продукта (ВРП) при построении сценарных прогнозов развития региональной экономики на примере «пилотного» региона - Республика Саха (Якутия). Авторы особое внимание уделяют проблеме сопоставимости статистической информации, полученной на федеральном и региональном уровнях, что определяется необходимостью согласования соответствующих прогнозных построений. Представлена оценка масштабов и направлений возможного изменения валового регионального продукта при переходе на новую методологию его исчисления ввиду проведенных в 2015 г. Федеральной службой государственной статистики (Росстат) пересчетов показателей системы национальных счетов (СНС) за 2011-2014 гг. на федеральном уровне. Описаны результаты экспериментального пересчета ВРП по новой методике, которые являются необходимыми для целей построения прогноза социально-экономического развития Республики Саха (Якутия) на период до 2035 г. в соответствии с предложенными сценариями: базовым, консервативным и целевым. Проведена корректировка динамики физического объема ВРП Республики Саха (Якутия) по сценариям с учетом изменения методологии расчета ВРП.

Distribution of immature stages of Aedes vigilax on a salt marsh in south-eastern Queensland

The distribution of eggs and larvae of Aedes vigilax was studied on part of a coastal salt-marsh in south-east Queensland. At the macro-scale (8 ha area), the largest numbers of larvae hatched were from samples taken in areas with relatively low open vegetation adjacent to drainage channels. Such areas are likely to be suitable for egg conditioning and hatching and are also accessible to adult mosquitoes. At the micro-scale (the environs of two small pools), most hatching occurred in narrow bands at specific elevations from the pool bottom but the relationship with vegetation was variable. Failure to hatch larvae from samples taken at the start of, or during, the cooler months was thought to be associated with egg diapause. At the macro-scale whilst the marsh was flooded, most larvae were found in two habitat types: the tall dense Sporobolus virginicus in relatively elevated locations and in depressions dominated by Sarcocornia quinqueflora. At the meso-scale (on a 1.4 ha grid) the distribution of larvae was found to be further related to water movement. Most larvae were in areas of slower water movement and appeared also to be redistributed by tides
