The economic viability of eco-friendly and renewable materials promotes the development of an alternative technology for climate change mitigation. Investigations reported over the past few years have allowed understanding the mechanism of action for a wide spectrum of saccharides toward carbon dioxide (CO2 ), in terms of reactivity, reversibility, stability and uptake. Exploiting bio-renewables, viz. , inedible saccharides, to reduce the anthropogenic carbon footprint upon providing a sustainable and promising technology that is of interest to different groups of scientists, to overcome demerits associated with the current state-of-the-art aqueous amine scrubbing agents, following a "green chemistry guideline", by employing materials with properties relevant to the environment toward sustainable development...

Information on how soil microbial communities respond to warming is still scarce for alpine scrub ecosystems. We conducted a field experiment with two plant treatments (plant removal or undisturbed) subjected to warmed or unwarmed conditions to examine the effects of warming and plant removal on soil microbial community structures during the growing season in a Sibiraea angustata scrubland of the eastern Qinghai-Tibetan Plateau. The results indicate that experimental warming significantly influenced soil microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN), but the warming effects were dependent on the plant treatments and sampling seasons...

Dissolving microneedles (DMNs) have been widely studied in medical applications due to their pain-free administration, superior efficiency, and safe drug delivery. In skin vaccination, preserving the activity of the encapsulated antigen is an important consideration, as antigen activity is lost during DMN fabrication because of various stress factors. These stress factors vary between fabrication methods and each method affects the antigen's activity to different degrees. In this study, the activity of encapsulated antigens delivered by DMNs is compared between two recently developed DMN fabrication methods; droplet-born air blowing (DAB) and centrifugal lithography (CL) for a model scrub typhus vaccine antigen, ScaA...

Introduction: Previously, we identified that 60% of our facility's total operative time is nonoperative. We performed a review of our operating room to determine where inefficiencies exist in nonoperative time. Methods: Live video of operations performed in a burn operating room from 6/23/17 to 8/16/17 were prospectively reviewed. Preparation (end of induction to procedure start) and turnover (patient out of room to next patient in room) were divided into the following activities: 1) Preparation: remove dressing, position patient, clean patient, drape patient, and 2) Turnover: clean operating room, scrub tray set-up, anesthesia set-up...

OBJECTIVES: Serology detecting IgM antibodies is the most widely used test to diagnose scrub typhus infection. However, kinetics of IgM and IgG antibodies post-infection remains elusive which could contribute to false positivity. The objective of this study is to document the nature of evolution of these antibody titers after infection. METHODS: Adult patients previously confirmed to have scrub typhus using IgM ELISA or positive PCR or both were included in this cross-sectional study...

Some metal etching operations emit limited flow rates of waste gases with reddish-brown NO2 fume which may cause visual and acidic-odor complaints as well as negative healthy effects. In this study, tests were performed by passing caustic-treated waste gases vented from Al-etching operations through columns packed either with virgin or regenerated GAC (granular activated carbon) to test their adsorptive conversion performance of NO2 in the gases. The gases contained 5-55 ppm NO2 and acetic and nitric acids of below 3 ppm...

Non-technical skills are the cognitive and interpersonal behaviours that compliment clinical competence in surgery. Effective use of non-technical skills is essential for scrub practice, because they facilitate anticipation of the surgeon's requirements and promote appropriate communication behaviours. This literature review analyses the factors that may influence a scrub practitioner's use of non-technical skills during surgery. Recommendations are made that are intended to improve their use by reducing behavioural variations during surgery...

BACKGROUND: Diagnosing scrub typhus clinically is difficult, hence laboratory tests play a very important role in diagnosis. As performing sophisticated laboratory tests in resource-limited settings is not feasible, accurate point-of-care testing (POCT) for scrub typhus diagnosis would be invaluable for patient diagnosis and management. Here we summarise the existing evidence on the accuracy of scrub typhus POCTs to inform clinical practitioners in resource-limited settings of their diagnostic value...

Previous research has suggested that videos can be used to experimentally manipulate social stimuli. In the present study, we used the California scrub-jays' cache protection strategies to assess whether video playback can be used to simulate conspecifics in a social context. In both the lab and the field, scrub-jays are known to exhibit a range of behaviours to protect their caches from potential pilferage by a conspecific, for example by hiding food in locations out of the observer's view or by re-caching previously made caches once the observer has left...
