INTRODUCTION Periodontal diseases are considered as some of the most common reasons of teeth loss, which occur due to the aggregation of microbial plaque and other precipitations on the dental surfaces. In this study, the scaling effect using manual tools, ultrasonic machine and Erbium-Doped Yttrium Aluminum Garnet (Er:YAG)laser on the connection of the human gums connective tissue cells on the...

Micro-alloyed High Strength Low Alloy steels (HSLA-steels) are widely used in civil construction, automobile and line pipe applications. They contain small quantities of alloying elements between 0,01 – 0,1 wt%, such as Niobium, Titanium, Vanadium, Aluminium and Nitrogen. These steels rely on thermo-mechanical rolling, a technique that simultaneously provides high strength, excellent toughness ...

Precipitations are one of the most important factors affecting water resources in transboundary Polish–Saxon region. The main goal research was to examine multiannual changes precipitations April–September period 1971–2018, depending on circulation conditions, based Ojrzy?ska’s classification. analysis carried out meteorological data from Polish and German stations. results showed that precipit...

This study's goal is to understand the structural events and episodes of fluid flow recorded in calcium carbonate precipitation sampled Mariana forearc serpentine mud volcanoes. Those active mounts provide a unique window deep affecting subduction channel mélange zone subducted Pacific Plate. To build conceptual model vein precipitations from volcanoes edifice, we unravelled origin, timing, mec...

The Mediterranean region is a hot spot for climate change, and cities of this area will be exposed to both increasing temperatures decreasing precipitations. Green Infrastructures (GIs) can lower urban through evapotranspiration with an adequate soil moisture content. Grey water reuse guarantee the right content reduce freshwater exploitation. In order test effectiveness on reducing air tempera...

A constrained stochastic weather generator (CSWG) for producing daily mean air temperature and precipitation based on annual from tree-ring records is developed tested in this paper. The principle stochastically generating assumes that temperatures any year can be approximated by a sinusoidal wave function plus perturbation the baseline. CSWG three additional assumptions: (1) In each month, tot...
