#1
Alireza Bazargan, Sarah L Rough, Gordon McKay
Palm kernel shell biochars (PKSB) ejected as residues from a gasifier have been used for solid fuel briquette production. With this approach, palm kernel shells can be used for energy production twice: first, by producing rich syngas during gasification; second, by compacting the leftover residues from gasification into high calorific value briquettes. Herein, the process parameters for the manufacture of PKSB biomass briquettes via compaction are optimized. Two possible optimum process scenarios are considered...

T cells play a key role in the adaptive immune response, and the ability to manipulate T cells for therapeutic uses has advanced in the past decade. Infusion of expanded or engineered T cells can potentially be used to treat cancer, viral infections, graft-versus-host disease, and organ transplant rejection. The role that blood banks play in the manufacture and distribution of T-cell therapeutics is still being defined. Given the regulatory framework of blood banks, they are well positioned to collect raw material for manufacture of T-cell therapies and to distribute finished product to hospitals in support of clinical trials or eventually for licensed products...

Donghua Xu, Yifan Xu
Vacuum injection casting (VIC) is important for research and development (R&D) of materials that are prone to oxidation at high temperatures, particularly metals and metallic alloys (e.g., metallic glasses and high entropy alloys). VIC in R&D laboratories often involves initial melting/alloying in a prior step, transporting the sample to a dedicated vacuum chamber, re-melting the sample in a quartz tube, and finally injecting the melt with an inert gas to a dedicated mold. Here we present a new approach to laboratory VIC that requires no sample transfer (for a variety of materials), no dedicated vacuum chamber/space nor dedicated mold, and hence provides more versatility and higher efficiency and yet lowers the capital equipment cost...

Introduction No study on hospital staff preparedness for managing blast injuries has been conducted in Libya. The internal conflict in Libya since 2011 and the difficulties faced by the hospitals has highlighted the need for such studies. Hypothesis Physicians working in Tripoli (capital city Libya) hospitals are inadequately prepared for the management of blast injuries. METHODS: A survey was conducted in all 13 hospitals in Tripoli between June 2014 and May 2015 by using interviews based on a questionnaire consisting of 29 questions covering physicians' education related to blast injury, hospital management of mass casualties, and aspects of hospital preparedness for such incidents...

Wenjing Ouyang, Peter E Hilsenrath
Investment, especially through merger and acquisition (M&A), is a leading topic of concern among health care managers. In addition, the implications of this activity for organization and market concentration are of great interest to policy makers. Using a sample of 2256 firm-year observations in the health care industry during the period from 1985 to 2011, this article provides novel evidence that managers learn from financial markets in making capital expenditure (CAPEX) and M&A investment decisions. Within the industry, managers in the Drugs subsector are most likely to do so, whereas managers in the Medical Equipment and Supplies are least likely to do so...

In this work a biotechnological multiproduct batch plant that manufactures four different recombinant proteins for human application is described in some detail. This batch plant design is then optimized with regards to the size of equipment using a mixed-integer linear programming (MILP) formulation recently developed by us in order to find a hypothetical new biotechnological batch plant based on the information of real known processes for the production of the four recombinant protein products. The real plant was divided for practical purposes into two sub-processes or facilities: a fermentation facility and a purification facility...

Oncolytic viruses represent a novel treatment modality that is unencumbered by the standard resistance mechanisms limiting the therapeutic efficacy of conventional antineoplastic agents. Attenuated engineered measles virus strains derived from the Edmonston vaccine lineage have undergone extensive preclinical evaluation with significant antitumor activity observed in a broad range of preclinical tumoral models. These have laid the foundation for several clinical trials in both solid and hematologic malignancies, which have demonstrated safety, biologic activity and the ability to elicit antitumor immune responses...

The Austral autumn-winter is a critical period for capital breeders such as Weddell seals that must optimize resource acquisition and storage to provision breeding in the subsequent spring. However, how Weddell seals find food in the winter months remains poorly documented. We equipped adult Weddell seals after their annual molt with satellite-relayed data loggers at two sites in East Antarctica: Dumont D'Urville (n = 12, DDU) and Davis (n = 20). We used binomial generalized mixed-effect models to investigate Weddell seals' behavioral response (i...

Radiation and potential risk during medical imaging is one of the foremost issues for the imaging community. Because of this, there are growing demands for accountability, including appropriate use of ionizing radiation in diagnostic and image-guided procedures. Factors contributing to this include increasing use of medical imaging; increased scrutiny (from awareness to alarm) by patients/caregivers and the public over radiation risk; and mounting calls for accountability from regulatory, accrediting, healthcare coverage (e...

We demonstrate a facile, plasma free process to fabricate both reversibly and irreversibly sealed microfluidic chips using a PDMS-based adhesive polymer mixture. This is a versatile method that is compatible with current PDMS microfluidics processes. It allows for easier fabrication of multilayer microfluidic devices and is compatible with micropatterning of proteins for cell culturing. When combined with our Shrinky-Dink microfluidic prototyping, complete microfluidic device fabrication can be performed without the need for any capital equipment, making microfluidics accessible to the classroom...

BACKGROUND: Ebola virus disease (EVD) is a viral hemorrhagic illness with great propensity for spread across international borders. The latest outbreak in the West African region, which involved Nigeria, was the worst among previously documented 25 outbreaks since discovery in 1976. The Nigerian response toward attaining Ebola free status was phenomenal and a case study for most nations. However, the persistence of EVD in West Africa is still a risk to recurrence, hence, the need to assess the level of consciousness of Nigerian physicians towards this...

BACKGROUND: Genomic technologies are increasingly used to guide clinical decision-making in cancer control. Economic evidence about the cost-effectiveness of genomic technologies is limited, in part because of a lack of published comprehensive cost estimates. In the present micro-costing study, we used a time-and-motion approach to derive cost estimates for 3 genomic assays and processes-digital gene expression profiling (gep), fluorescence in situ hybridization (fish), and targeted capture sequencing, including bioinformatics analysis-in the context of lymphoma patient management...
