Buffers

open access: yesCold Spring Harbor Protocols, 2018
Biological reactions work well only within a narrow concentration range of hydrogen ions. Paradoxically, however, many of these reactions themselves generate or consume protons. Buffers are substances that undergo reversible protonation within a particular pH range and therefore maintain the concentration of hydrogen ions within acceptable limits. This

Assessing the effectiveness of riparian buffers in protecting biodiversity: a meta-analysis [PDF]

open access: yesNature Communications
Riparian buffers – vegetation strips retained or established along waterways – are mandated in many countries for water and soil protection, yet their role in biodiversity conservation remains unclear.

Replacing Store Buffers by Load Buffers in TSO

open access: yes, 2018
We consider the weak memory model of Total Store Ordering (TSO). In the classical definition of TSO, an unbounded buffer is inserted between each process and the shared memory. The buffers contains pending store operations of the processes. We introduce a new model where we replace the store buffers by load buffers.

Association of Salivary Mucin-7 Levels with Dental Caries in Adults

open access: yesCentral Asian Journal of Medical Sciences, 2022
Objectives: This study examines the potential relationship between the incidence of dental caries in adults and the level of mucin-7 glycoprotein, a specific parameter in saliva. Methods: In a case-control study, samples of whole unstimulated saliva from

Acidification of till in Northern Finland: experimental study [PDF]

open access: yesBulletin of the Geological Society of Finland, 1996
The acid neutralizing capacity of till and some effects promoted by increasing acidity, were studied in a number of tills in northern Finland. pH profiles were measured in the field and acid neutralizing capacity (ANC mmol/100 g sample) in the laboratory

Non-carbonic buffer power of whole blood is increased in experimental metabolic acidosis: An in-vitro study

open access: yesFrontiers in Physiology, 2022
Non-carbonic buffer power (βNC) of blood is a pivotal concept in acid-base physiology as it is employed in several acid-base evaluation techniques, including the Davenport nomogram and the Van Slyke equation used for Base excess estimation in blood.

Using hand-draw maps of residential neighbourhood to compute level of circularity and investigate its predictors [PDF]

open access: yesHuman Geographies: Journal of Studies and Research in Human Geography, 2015
Investigating individuals’ Hand-Drawn Residential Neighbourhood (HDRN) maps may help determine some of the basic geometrical properties found in cognitive maps of meaningful geographical spaces.

Comparison of Salivary pH, Buffering Capacity and Alkaline Phosphatase in Smokers and Healthy Non-Smokers : Retrospective cohort study

open access: yesSultan Qaboos University Medical Journal, 2016
Objectives: Saliva contains alkaline phosphatase (ALP)—a key intracellular enzyme related to destructive processes and cellular damage—and has buffering capacity (BC) against acids due to the presence of bicarbonate and phosphate ions.

Significance of pH cyclization in amelogenesis

open access: yesFogorvosi Szemle, 2021
The process of amelogenesis is well understood at the histomorphological level, but the regulation of crystal formation and the underlying molecular mechanisms are still largely unknown.
