Root restriction improved berry quality by being involved in diverse aspects of grapevine life. However, the molecular mechanism driving this process is not understood very well. In this study, the 'Summer Black' grape berry (Vitis vinifera × V. labrusca) under root restriction was investigated, which showed an increase of total soluble solids (TSS), color index of red grapes (CIRG) value, anth...

Aims Since the inception of the cleaning and shaping concept, the use of instruments and chemicals has remained as the central paradigm of the root canal therapy. However, cleaning and shaping the root canal space adequately is a well-known difficult task, particularly in root canal systems with intercanal connections, isthmuses, and fins. Recently, micro-computed tomography (micro-CT) technolo...

Effective decontamination of root canal systems is a constant concern in clinical practice. In this article, we compare the performance of photodynamic therapy (PDT) and sodium hypochlorite (NaOCl) in reducing the amount of Enterococcus faecalis in root canals. Relevant studies were identified by searching electronic databases, including Web of Science, PubMed, BVS (Medline, Scielo, Lilacs and ...

A new technique for finding the root cause for problems in a manufacturing process is presented. The new technique is designated to continuously and automatically detect quality drifts on various manufacturing processes and then induce the common root cause. The proposed technique consists of a fast, incremental algorithm that can process extremely high dimensional data and handle more than one...

Cassava (Manihot esculenta Crantz) is an important tropical starchy root crop that is adapted to drought but extremely cold sensitive. A cold-tolerant, high-quality, and robust supply of cassava is urgently needed. Here, we clarify genome-wide distribution and classification of CCGG hemi-methylation and full-methylation, and detected 77 much candidate QTLsepi for cold stress and 103 much candid...

Microbiota are found in highly organized and complex entities, known as biofilms, the characteristics of which are fundamentally different from microbes in planktonic suspensions. Root canal infections are biofilm mediated. The complexity and variability of the root canal system, together with the multi-species nature of biofilms, make disinfection of this system extremely challenging. Microbia...

Evidence on the impact of amplification, or bullwhip, effects on supply chain performance has primarily been derived from studies in manufacturing industries. This paper reports on a case study from the telecommunication industry, aiming to analyze relevant root causes and associated counter-measures of the amplification phenomenon in service supply chains. Case findings confirm the occurrence ...

The purpose of the study was to compare the incidence and severity of apical root resorption in patients treated with different orthodontic appliances and to evaluate the effect of treatment duration on the degree of apical root resorption. A further aim was to analyse the degree of apical root resorption in different tooth groups in patients presenting with root resorption. The sample consiste...
