Science Identity among Latinx Students in the Biomedical Sciences: The Role of a Critical Race Theory-Informed Undergraduate Research Experience.

Tissyana C Camacho, Yolanda Vasquez-Salgado, Gabriela Chavira, David Boyns, Scott Appelrouth, Carrie Saetermoe, Crist Khachikian,

Underrepresented racial minority (URM) students in science, technology, engineering, and mathematics majors encounter educational, social, and structural challenges on the path toward their degrees and careers. An undergraduate research program grounded in critical race theory was developed and implemented to address this disparity. NIH BUILD PODER focuses on developing science ... Read more >>

Critical race theory as a bridge in science training: the California State University, Northridge BUILD PODER program.

Carrie L Saetermoe, Gabriela Chavira, Crist S Khachikian, David Boyns, Beverly Cabello,

<h4>Background and purpose</h4>Unconscious bias and explicit forms of discrimination continue to pervade academic institutions. Multicultural and diversity training activities have not been sufficient in making structural and social changes leading to equity, therefore, a new form of critical consciousness is needed to train diverse scientists with new research questions, methods, ...

Laboratory investigations of weathering of soils from Mammoth Mountain, CA, a naturally CO2-impacted field site.

Helen Sanchez, Gustavo Menezes, Andre Ellis, Claudia Espinosa-Villegas, Crist Khachikian,

The potential impacts of CO2 leakage from a natural subsurface reservoir on soil and water quality were studied. Field measurements of soil pore CO2 concentrations and visual inspection of plants at Mammoth Mountain, CA, allowed the demarcation of tree-kill and non-tree-kill zones, with CO2 concentrations >100,000 ppm and ∼ 1,000 ...

Design and development of an automated flow injection instrument for the determination of arsenic species in natural waters.

Grady Hanrahan, Tina K Fan, Melanie Kantor, Keith Clark, Steven Cardenas, Darrell W Guillaume, Crist S Khachikian,

The design and development of an automated flow injection instrument for the determination of arsenite [As(III)] and arsenate [As(V)] in natural waters is described. The instrument incorporates solenoid activated self-priming micropumps and electronic switching valves for controlling the fluidics of the system and a miniature charge-coupled device spectrometer operating in ...

The development of iodide-based methods for batch and on-line determinations of phosphite in aqueous samples.

Roman A Barco, Deepa G Patil, Weihong Xu, Lin Ke, Crist S Khachikian, Grady Hanrahan, Tina M Salmassi,

Recent developments in the field of microbiology and research on the origin of life have suggested a possible significant role for reduced, inorganic forms of phosphorus (P) such as phosphite [HPO(3)(2-), P(+III)] and hypophosphite [H(2)PO(2)(-), P(+I)] in the biogeochemical cycling of P. New, robust methods are required for the detection ... Read more >>

Detection of hypophosphite, phosphite, and orthophosphate in natural geothermal water by ion chromatography.

Monica M McDowell, Michelle M Ivey, Mary E Lee, Verena V V D Firpo, Tina M Salmassi, Crist S Khachikian, Krishna L Foster,

Current doctrine states that phosphorus is incorporated into cells in the pentavalent(V) oxidation state as orthophosphate. However, recent studies show that microorganisms contain enzymes used to metabolize reduced forms of phosphorous, including phosphite(III) and hypophosphite(I), which suggests that there is a natural source for these chemical species. This paper will ... Read more >>

Reduced inorganic phosphorus in the natural environment: significance, speciation and determination.

Grady Hanrahan, Tina M Salmassi, Crist S Khachikian, Krishna L Foster,

It is commonly assumed that phosphorus occurs almost exclusively in the environment as fully oxidized phosphate (primarily H(2)PO(4)(-) and HPO(4)(2-), where the oxidation state of phosphorus is +V). Recent developments in the field of microbiology and research on the origin of life have suggested a possibly significant role for reduced, ... Read more >>

Long-term studies on the effects of nonvolatile organic compounds on porous media surface areas.

Crist S Khachikian, Thomas C Harmon,

This paper investigates the long-term behavior of porous media contaminated by nonvolatile organic compounds (NVOC) in terms of specific interfacial surface area. Specifically, a natural sand, Moffett sand (MS), was contaminated with naphthalene and the surface area was measured repeatedly over time using nitrogen adsorption-desorption techniques. A field-contaminated sand affected ... Read more >>
