Gain saturation in gas flow and chemical lasers

open access: yes, 1985
A theoretical model for gain saturation in gas flow and chemical lasers is presented. The theory is applicable to all possible numerical values of τ/τc, where τ is the characteristie flow time for the flowing gas to move across the laser action region ...

Saturation Flow Rate and Start-up Lost Time of Dual-left Lanes at Signalized Intersection in Rainy Weather Condition

open access: yes, 2013
This study aims at finding out the difference of saturation flow rate and start-up lost time at dual left lanes between normal and rainy weather. It is based on the investigation of a signalized intersection in Shanghai. The result shows that compared to

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Thermodynamic performance analysis of direct evaporative cooling system for increased heat and mass transfer area

open access: yesAin Shams Engineering Journal, 2018
This paper demonstrates the thermodynamic performance analysis of direct evaporative cooling system by increasing sides of cooling media. In this paper, a different configuration of cooling media has been developed for determining the behaviour pattern ...

Field measurement of ideal saturation flow rate from the highway capacity manual [PDF]

open access: yes, 2005
In all signalized intersection analyses performed with Highway Capacity Manual (HCM), the Pennsylvania Department of Transportation (PENNDOT) District 12-0 uses an ideal saturation flow rate of 1800 pcphgpl, which is less than the default value of 1900 ...

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

open access: yesMolecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

open access: yesFEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Saturation flow versus green time at two-stage signal controlled intersections [PDF]

open access: yesTransport, 2009
Intersections are the key components of road networks considerably affecting capacity. As flow levels and experience have increased over the years, methods and means have been developed to cope with growing demand for traffic at road junctions.

Effect of pad water flow rate on evaporative cooling system efficiency in laying hen housing

open access: yesJournal of Agricultural Engineering, 2020
An experiment was conducted in three commercial laying hen houses with 32-week-old hens in the summer of 2017 in a commercial farm in Gharbia Province, Egypt (31.06ºN, 31.16ºE) using an evaporative pad cooling system to determine the most suitable water ...
