The dynamics of a two-wheeled vehicle represent a higher level of complexity, with a high variety of rider practices, peculiarly during the bend-taking maneuver. This complexity is one reason why research on motorcyclists' practiced trajectories is limited compared to cars. Another reason is the low representation of motorcycles in the land motor vehicle fleet.

The objective of this review is to provide an overview of existing knowledge on with regards to its botanical description, ethnomedicinal uses, and pharmacological properties. Databases such as Scopus, Wiley-Online, PubMed, Springer, Google Scholar, and ScienceDirect were used to select relevant articles based on their title and abstract.

MicroRNAs have been proposed as relatively non-invasive and pertinent biomarkers. miR-93 has been studied for its potential as a diagnostic and prognostic marker in prostate cancer (PCa), but findings from individual studies are inconsistent.

The dataset contains different sequences acquired with different modalities, including RGB, IR, and depth images in passive stereo and active stereo modes. Each sequence is associated with a reference trajectory constructed with an Structure From Motion (SFM) and Multi View Stereo (MVS) library for comparison.

The build of neutron imaging facility is planned in the tangential beam around the TRIGA 2 MW, located in the Mâamora Nuclear Research Centre of Morocco. The design of this equipment and the plans for all operations should be evaluated in advance for the adequacy of radiation protection. Cement and concrete has been widely used as shielding material in a nuclear reactor in order to minimize exposure to individuals.

Objective: To determine predictors of cranio-cerebral lesions (CCL) in the case of MHI in children.
Methods: Case-control study over a period of 3 years.
Background: Multi-drug resistance (MDR) TB is defined as tuberculosis (TB) disease caused by a strain of Mycobacterium tuberculosis (MTB) that was resistant to at least isoniazid and rifampicin (RIF). Emerging Multidrug-Resistant TB is one of the major concerns of health policy and rapid detection of M. tuberculosis and detection of RIF resistance in infected patients are essential for disease management.

In the present study we applied radio-frequency (RF) signals of the Universal Mobile Telecommunications System (UMTS) to full brain exposed male Wistar rats in order to elaborate putative influences on stress hormone release (corticosteron; CORT and adrenocorticotropic hormone; ACTH) and on hippocampal derived synaptic long-term plasticity (LTP) and depression (LTD) as electrophysiological hallmarks for memory storage and memory consolidation. Exposure was computer controlled providing blind conditions.

The waveguides were based on a fin-line concept and the chamber containing the samples bathed in extracellular solution was placed onto two fins with a slot in between, where the exposure field concentrates.

Radial waveguide set-ups are introduced as exposure devices for long-term experiments with large numbers of non-restrained animals exposed simultaneously. Methods are presented to ensure well-defined exposure conditions even for potentially overmoded waveguides and for the exposure of large groups of animals per cage. The proposed methods are applied for a four-generation study being performed on up to 2500 mice exposed to a generic UMTS test signal at prescribed averaged whole body specific absorption rates (SARs).
