imageData: Aids in Processing and Plotting Data from a Lemna-Tec Scananalyzer
Note that 'imageData' has been superseded by 'growthPheno'. The package 'growthPheno' incorporates all the functionality of 'imageData' and has functionality not available in 'imageData', but some 'imageData' functions have been renamed. The 'imageData' package is no longer maintained, but is retained for legacy purpo…

Perfluorinated chemicals taint drinking water
Remnants of past industrial chemical innovation linger in rivers and aquifers that supply drinking water to millions of people in the U.S., and more worldwide, potentially putting their health at risk. Dissolved in the water are perfluorinated compounds that gave rise to iconic household brands such as 3M’s Scotchgard…
Analysis, Characterization and Application of Microwave Metamaterials
Metamaterials are an extremely fast growing and interesting field of study.The promise of new materials whose constitutive parameters are based on structure inclusions have drawn the interest of thousands and continue to inspire.Despite these promises not much in the way of applied technologies has come from the resea…

APPLICATION: GRAPHENE NANOCOMPOSITE FOR IMPROVEMENT OF VACCINE TRANSPORTATION COLD CHAIN
Vaccines are biological products that must be kept between 2˚C and 8˚C. If not, they lose effectiveness to the point of total inactivity. Seeking to enhance the useful life of vaccines when they must be transported to remote locations, the use of a mobile monitored cooling system (SMRM, by its Spanish acronym) using a…
PENGARUH PRE HEAT PADA SAMBUNGAN BUTT JOINT MATERIAL SS400 TERHADAP NILAI TENSILE STRENGTH, UJI METALLOGRAPHY DAN HARDNESS TEST DENGAN PENGELASAN GMAW DI PT.INKA MADIUN
Abstrak Pada pengelasan terdapat beberapa macam jenis perlakuan panas seperti pre heat. Pre heat adalah bagian dari proses heat treatment yang bertujuan untuk menghilangkan tegangan sisa yang dilakukan sebelum proses welding dimulai dan untuk mengurangi laju pendingin sehingga mengurangi pembentukan baja martensit. Pe…
Exploring the imaging properties of thin lenses for cryogenic infrared cameras
Designing a cryogenic camera is a good strategy to miniaturize and simplify an infrared camera using a cooled detector. Indeed, the integration of optics inside the cold shield allows to simply athermalize the design, guarantees a cold pupil and releases the constraint on having a high back focal length for small foca…
Approaches for CO2 Capture and Sequestration Inspired by Biological Systems
Abstract In this study, several process alternatives for the permanent sequestration of carbon dioxide (CO2) as solid carbonates are evaluated. Although the formation of mineral carbonates is thermodynamically favourable, it does not occur significantly due to kinetic limitations and the formation of products that hin…
A New Trinodal (3,4,6)-Connected Ni(II) Coordination Polymer Based on the Mixed Ligands of 6-(3′,4′-Dicarboxyl-Phenoxy) Isophthalic Acid and 4,4′-Bipyridine
Reported here is a new Ni(II) compound, namely {Ni2(L)(bipy)2(H2O)2}n (1 H4L = 6-(3′,4′-dicarboxyl-phenoxy)isophthalic acid, bipy = 4,4′-bipyridine), which has been synthesized via the solvothermal reactions of Ni(NO3)2·6H2O, H4L and bipy. Single crystal X-ray analysis reveals that compound 1 crystallizes in triclinic…
Transformation optics relay lens design for imaging from a curved to a flat surface
Monocentric lenses are excellent candidates for compact, broadband, high resolution, wide-field imaging. Traditional monocentric designs produce a curved image surface and have therefore found limited utility. The use of an appropriately machined fiber bundle to relay the curved image plane onto a flat focal plane arr…
Linear response approximation in effective field theory for the calculation of elastically mediated interactions in one dimension
The linear response approximation, used within effective field theory to calculate mediated interactions between inclusions, is studied for an exactly solvable one-dimensional model. We show that it works poorly in the case of inclusions imposing absolute deformations to the field, while it works well for massless the…
Structural and electronic characteristics of intercalated monopotassium–rubrene: Simulation on a commodity computing cluster
The structural and electronic characteristics of the intercalated monopotassium–rubrene (K1Rub) are studied. In the intercalated K1Rub, one of the two pairs of phenyl groups of rubrene is intercalated by potassium, whereas the other pair remains pristine. This structural feature facilitates the comparison of the elect…
Physical Damages of Wood Fiber in Acacia Mangium due to Biopulping Treatment
Biopulping is fungal pretreatment of wood chips to reduce unused chemical composition of material in pulping. Preliminary study showed that pretreatment of Phanerochaetachrysosporium to Acacia mangium Willd can reduce lignin and improve holocellulose and cellulose content of the material. Fiber dimension recognized as…
The effect of embedded nanopillars on the built-in electric field of amorphous silicon p-i-n devices
In this work, we report on the experimental modification of the built-in electric field of a-Si:H p-i-n junctions, resulting from Ag nanopillars embedded within the intrinsic layer (i-layer). Increased open-circuit voltages, from J-V traces, and reduced charge transit-times, from time-of-flight (ToF) measurements, ind…
A new mixed method for nonlinear fuzzy free vibration analysis of nanobeams on nonlinear elastic foundation
A new mixed method for nonlinear fuzzy free vibration analysis of nanobeams on nonlinear elastic foundation is introduced. The governing equations are derived based on the first-order shear deformation theory (FSDT) in conjunction with the von-Kármán’s assumptions and the Eringen’s nonlocal elasticity theory. The diff…
