Organizational and Functional Principles of the Obligate Respiratory Chain Supercomplex

Journal of the Chinese Chemical Society, EarlyView.
In this review we deliver a comprehensive structural analysis of the actinobacterial respiratory chain supercomplex and discuss the principles underlying the assembly of its supramolecular architecture. ABSTRACT Proton translocating respiratory chain complexes assemble into supramolecular structures in their native cellular environment, yet the ...

Association between ADHD symptoms and device‐measured physical activity and sedentary behavior in childhood: A population‐based twin study

JCPP Advances, EarlyView.
Abstract Background Attention‐deficit/hyperactivity disorder (ADHD) symptoms are associated with adverse health outcomes; this may be partially due to unhealthy lifestyle factors such as low physical activity (PA) and high sedentary behavior (SED). However, this association remains unclear.

Microbial burden of periodontal diseases and its clinical application: The stage, grade, and furcation matter

Journal of Periodontology, EarlyView.
Abstract Background Periodontal diseases are associated with dysbiotic oral microbial communities, but clinically applicable measures that reflect microbial burden across disease severity and progression remain limited. This study aimed to assess the oral microbial burden of periodontal diseases by evaluating salivary and subgingival lipopolysaccharide

Transmission Raman Spectroscopy (TRS) for Accurate Authentication of API in Coated Hydroxychloroquine (HCQ) Tablets

Journal of Raman Spectroscopy, EarlyView.
We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater

Homogenization of sandwich panels [PDF]

, 2015
The numerical modeling of plates with periodic corrugationrequires some efforts to be made in terms ofcareful and precise discretization of the complicated structure. This automatically generates very com-putationally expensive models. One of the most popular methods of model simplification is analytical ornumerical homogenization.

Incremental Forming of Sandwich Panels

Journal of Materials Processing Technology, 2007
This paper presents a first investigation of the applicability of incremental sheet forming (ISF) to sandwich panels. Two initial tests on various sandwich panel designs established that sandwich panels which are ductile and incompressible are the most suitable for the process.

Sandwich acoustic panel

The Journal of the Acoustical Society of America, 2004
An acoustic panel with several degrees of freedom comprises a resistive layer (14), a compartmentalized structure (16) formed from at least two superposed compartmentalized layers (18) and a back reflector (17), starting from an outside face facing an incident acoustic wave.
