Ionomer Morphology, Solution to Film Thermodynamics, Molecule Transport, Physical Properties, and Water Desalination via Electrodialysis

Of the different classes of separation polymers, ionomers are considered one of the most advanced and versatile. They have been successfully utilized in various industrial fields, including electrodialysis, electrolysis, diffusion dialysis, solid polymer electrolyte batteries, sensing materials, medical use, and analytical chemistry. In this study, an ionomer film series of penta block copolymer (PBC, poly(t-butyl styrene-bhydrogenated isoprene-b-sulfonated styrene-b-hydrogenated isoprene-b-t-butyl styrene) (tBSHI-S-HI-tBS)), sPP (sulfonated polyphenylene), aminated PPSU-TMPS block copolymer (polyphenyl sulfone-tetramethyl polysulfone), and Nafion were investigated with respect to thermodynamics, morphology, mechanical and transport properties. First, the thermodynamic interrelationships between wettability, surface energy, solubility, and swelling were studied in order to probe ionomer relationships between microscopic interactions and macroscopic physical properties. Choosing an appropriate surface energy model and an optimal solubility prediction method is an important role in the study of intrinsic and extrinsic
Space-Based Localization of Radio Frequency Transmitters Utilizing Macaulay Resultant and Heuristic Optimization Methods

Space was once a rarely traveled domain but it is quickly becoming more accessible. More countries are developing space programs and more civilian companies are investing time and resources to exploring the reaches. When automobiles became accessible to the masses, roads had to be paved, traffic laws had to be written, and multiple local and national agencies stood up to monitor and enforce the domain. When airplanes became accessible, routes needed to be planned, traffic laws had to be written, and again multiple local and national agencies stood up to monitor and enforce the domain. The same is happening with the space domain. Space is becoming accessible enough to need planned trajectories, traffic laws, and an agency to monitor and enforce those safeguards. That agency will need all tools possible at their disposal to provide the best coverage and maintain space domain awareness, which requires accurate, timely, and precise knowledge of the tens of thousands of space objects. This research focuses on radio frequency geolocation of space objects utilizing space-based platforms. Geolocation has long been the solution for locating objects. Technically, geolocation is the process of locating something on Earth (geo) but the term has been applied to all aspects of locating objects. In particular, this study examines the scenario of two cooperative receivers geolocating (or in this context, astrolocating) a transmitter in close proximity. A MATLAB algorithm is developed in this research to calculate the initial estimated transmitter location and projected orbital trajectory. The algorithm uses the Macaulay method of solving a system of polynomials as well as heuristic optimization techniques to locate a transmitter with respect to receivers at different time intervals. For the scenarios investigated, both iv Macaulay and heuristic optimization methods achieve initial relative orbit determination for the transmitter.

Reticulon and CLIMP-63 regulate nanodomain organization of peripheral ER tubules

The endoplasmic reticulum (ER) is an expansive, membrane-enclosed organelle composed of smooth peripheral tubules and rough, ribosome-studded central ER sheets whose morphology is determined, in part, by the ER-shaping proteins, reticulon and CLIMP-63, respectively. Here, STimulated Emission Depletion (STED) super-resolution microscopy shows that reticulon4a (RTN4a) and CLIMP-63 also regulate the organization and dynamics of peripheral ER tubule nanodomains. STED imaging shows that lumenal ERmoxGFP, membrane Sec61βGFP, knock-in calreticulin-GFP and antibody-labeled ER resident proteins calnexin and derlin-1 are all localized to periodic puncta along the length of peripheral ER tubules that are not readily observable by diffraction limited confocal microscopy. RTN4a segregates away from and restricts lumenal blob length while CLIMP-63 associates with and increases lumenal blob length. RTN4a and CLIMP-63 also regulate the nanodomain distribution of ER resident proteins, being required for the preferential segregation of calnexin and derlin-1 puncta away from lumenal ERmoxGFP blobs. High-speed (40 ms/frame) live cell STED imaging shows that RTN4a and CLIMP-63 regulate dynamic nanoscale lumenal compartmentalization along peripheral ER tubules. RTN4a enhances and CLIMP-63 disrupts the local accumulation of lumenal ERmoxGFP at spatially defined sites along ER tubules. The ER shaping proteins reticulon and CLIMP-63 therefore regulate lumenal ER nanodomain heterogeneity, interaction with ER resident proteins and dynamics in peripheral ER tubules.
Diel, seasonal, and interannual patterns in mesozooplankton abundance in the Sargasso Sea

&NA; Temporal changes in mesozooplankton abundance affect planktonic food web interactions and biogeochemistry. We enumerated mesozooplankton from monthly day and night tows in the epipelagic zone at the Bermuda Atlantic Time‐series Study (BATS) site in the Sargasso Sea (1999‐2010). Abundances of each taxon were determined using a ZooScan imaging system and microscopy. Generalized linear models were used to determine environmental parameters that best explained abundance patterns. Taxa with pronounced diel vertical migration included euphausiids, amphipods, Limacina spp. pteropods, and other shelled pteropods. Taxa with a pronounced spring abundance peak included euphausiids, appendicularians, and Limacina spp. , while harpacticoid copepods peaked in late summer, and calanoid copepods in late winter/early spring and summer. Many taxa increased in 2003, coincident with a diatom bloom and the largest primary production peak in the time series. Long‐term, increasing trends occurred in calanoid and oncaeid copepods, and ostracods, with barnacle nauplii significantly increasing. Sub‐decadal‐scale climate oscillations and long‐term warming may be driving decreases in shelled pteropods and appendicularians. Chaetognath abundance increased in response to increased density of a major prey taxon, calanoid copepods. Calanoid copepods and ostracods increased with increasing water column stratification index and the Atlantic Multidecadal Oscillation index, indicating warmer sea surface temperatures favour these taxa.

EFFECTS OF LYSINE SUPPLEMENTED ON GROWTH AND NUTRIENT DIGESTIBILITY OF NOI CHICKENS FROM 1 TO 56 DAYS OLD

A total of 256 one-day-old chicks were allocated into a completely randomized design with 4 treatments and 4 replicates to evaluate growth, feed conversion ratio (FCR), and nutrient digestibility (ND) of Noi chickens. The treatments consisted of control diets (Lys0) containing 1.0 and 0.9% lysine for birds 1 to 28 and 29 to 56 days of age respectively; 3 other treatments (Lys1; Lys2; Lys3) had 0.1, 0.2, 0.3% of lysine added to diets respectively. Dietary crude protein (CP) was calculated to 19% and 17% for 1 to 28 and 29 to 56 days old, but dietary ME was 2.900 kcal/kg of feed for the entire duration of the study. On the last seven days of each period, one male and one female per replicate were selected to be assessed for apparent ND by ferric oxide (Fe2O3) marker. Birds were fed, provided fresh water ad libitum, and vaccinated to prevent some common diseases. Results showed that lysine supplemented 0.2 to 0.3% and 0.3% in diets for the birds between 1 to 28 and 29 to 56 days old
Vascular Implications of the Krüppel-Like Family of Transcription Factors

The Kruppel-like factor (KLF) family is a recently highlighted group of zinc finger transcription factors given their important biological roles which include the vasculature. KLF2, KLF4, KLF5, and KLF6 are notable factors that have been implicated in developmental as well as pathological vascular processes. In this brief review, we provide an up-to-date summary of the physiological functions and cellular effects as well as transcriptional regulatory mechanisms of the vascular KLFs. Through such, we aim to provide a working view for understanding the pathological actions of KLFs in the vasculature.
The heck reactions of aryl bromides in ionic liquids medium of n-butyl-n-methylpyrrolidinium trifluoromethanesulfonate

The application of the ionic liquids in the palladium catalyzed Heck reactions have been reported extensively, however, without proper evidence addressing the role of ionic liquids in the catalytic process. In this thesis, a new series of N-alkyl-Nmethylpyrrolidinium trifluoromethanesulfonate salts (46-52) have been synthesized to study their potential as the alternative solvents for the Heck reaction, instead of using conventional molecular solvents. These salts were synthesized through quaternization reaction between N-methylpyrrolidine (38) with several alkyl iodides, followed by metathesis reaction with silver trifluoromethanesulfonate, to give the desired products (46-52) (yield: 72-96%) with melting points ranging from room temperature to 300Â°C. All the salts obtained were characterized by using 1H and 13CNMR spectroscopies, CHN elemental analysis, melting point, density and molar conductivity. The effects of alkyl chains towards the melting points and molar conductivities of these salts (46-52) have been investigated. The N-butyl-Nmethylpyrrolidinium trifluoromethanesulfonate, [Bmplim]CF3SO3 (49), has been chosen as the solvent in the Heck reactions between methyl acrylate (61) and several types of aryl bromides (56-60) to give Heck adducts (62-66) with satisfactory yield between 37 to 97%. Parameters such as the types of bases, the amount of Pd catalyst loadings and the reaction temperatures were also studied in order to optimize the percentage conversion of respective Heck adducts (62-66). Results show that, the optimum condition to enhance the percentage conversion for this catalytic system is by using Et3N as base, Pd catalysts loading at 1.5mmol% and reaction temperature at 120Â°C, to achieve the calculated TONs of ~6667. With these conditions, the Heck adducts of reactive aryl bromides; 4-bromonitrobenzene (56), 4-bromoacetophenone (57) and bromobenzene (58) have achieved an extremely high percentage conversion (~100%). As for the unreactive aryl bromides; 4-bromoanisole (59) and 4- bromoaniline (60), the addition of PPh3 was proved to be useful; however, leads to contamination from the by-product which results to problematical separation of the desired products (62-66). The ionic liquid of [Bmplim]CF3SO3 (49), can be recycled up to three runs, without showing any distinct losses in its activities
Breast cancer screening: in the era of personalized medicine, age is just a number.

“The great end of life is not knowledge but action. ”—Thomas Henry Huxley. While breast cancer screening has a long and established history dating back to the 1960s, screening programs still allow for little to none personalization, both when considering the choice of the imaging technique and the age boundaries, save for specific groups of highrisk women (1). This almost “one-size-fits-all” paradigm currently characterizes most European and North American screening strategies (1-4), with only few exceptions (5,6). A study by Mukama et al. (7) recently published in JAMA Oncology under the title “Risk-Adapted Starting Age of Screening for Relatives of Patients With Breast Cancer”, aimed to improve and refine the age-related side of screening strategies for women outside the restricted high-risk category. By analyzing data from more than 5 million women born from 1932 onwards and included in the Swedish breast cancer screening registry from 1958 to 2015, the authors stratified women in 15 categories according to the number of their firstand second-degree relatives with a proved diagnosis of breast cancer, then they calculated how much each woman should bring forward or delay the beginning of her screening examinations to match the average 10-year cumulative breast cancer risk at which screening is currently recommended to begin in the general population (7,8). Of note, increasingly earlier risk-adapted starting ages are already suggested by this study when a woman has only one second-degree relative with breast cancer (7). When compared with guidelines that recommend a screening mammography starting age of 50 years—such as the ones from the US Preventive Services Task Force (3) and the International Agency for Research on Cancer (2), widely adopted also in European countries—starting ages calculated by Mukama et al. (7) would call for a 5-year-earlier start (i.e., 45 years of age) in women with no more than one second-degree relative with breast cancer and as much as a 24-year-earlier start (i.e., 26 years of age) in a woman that has at least a first-degree relative and a second-degree relative diagnosed with breast cancer before age 40. These differences are of course curtailed when a 45 years screening starting age is considered, as suggested for example by the American Cancer Society guidelines (4) or, albeit with a conditional recommendation, by the European Commission Initiative on Breast Cancer (1): if a woman has no more than a second-degree relative with breast cancer, a 3-yearearlier start would be recommended, while a 20-year-earlier start would be recommended for a woman that has at least a Editorial Commentary
Longitudinal follow-up Study of the Intrarenal Hemodynamics and Pulmonary Function in Patients with T2DM

Purpose: The main aim of this study is to long-range assess incidence of diabetic kidney disease (DKD) and pulmonary function in patients with type 2 diabetes mellitus (T2DM) during 2000 and 2015. Methods: 60 subjects newly diagnosed with T2DM were divided into two groups according to their arterial resistivity index (RIs) (≤0.7 and >0.7). These patients underwent tests designed to assess the early changes in pulmonary function and intrarenal haemodynamics associated with diabetes, the results of which were compared to corresponding test results for the same group of patients between 2000 and 2015. The endpoints of the study were the between-group differences in the changes in the pulmonary functional parameters, the mean kidney arterial RI in the bilateral interlobular renal arteries, and the indicated renal functional parameters (BUN, Cr, AER, and UACR). Results: The subjects with RIs ≤0.7 displayed significantly better pulmonary function in the year 2000 than subjects with RIs >0.7. Moreover, subjects in the former group displayed improvement and smaller decreases in their pulmonary functional parameters from 2000 to 2015 compared to subjects in the latter group. Additionally, subjects in the former group displayed improvement and smaller increases in their renal functional parameters, i.e., their BUN and Cr, and their AERs and UACRs from 2000 to 2015 compared to subjects in the latter group. The incidence of DKD in the group with RIs ≤0.7 (6/25, 24.00%) was significantly lower than that in the group with RIs >0.7 (23/45, 65.71%) (P<0.05). Conclusion: The renal functional parameters, the right kidney RI may also serve as a predictor of diabetes-related changes in pulmonary function and renal injury in the future.

Single-Cell Transcriptomics Reveals Early Emergence of Liver Parenchymal and Non-parenchymal Cell Lineages

The cellular complexity and scale of the early liver have constrained analyses examining its emergence during organogenesis. To circumvent these issues, we analyzed 45,334 single-cell transcriptomes from embryonic day (E)7.5, when endoderm progenitors are specified, to E10.5 liver, when liver parenchymal and non-parenchymal cell lineages emerge. Our data detail divergence of vascular and sinusoidal endothelia, including a distinct transcriptional profile for sinusoidal endothelial specification by E8.75. We characterize two distinct mesothelial cell types as well as early hepatic stellate cells and reveal distinct spatiotemporal distributions for these populations. We capture transcriptional profiles for hepatoblast specification and migration, including the emergence of a hepatomesenchymal cell type and evidence for hepatoblast collective cell migration. Further, we identify cell-cell interactions during the organization of the primitive sinusoid. This study provides a comprehensive atlas of liver lineage establishment from the endoderm and mesoderm through to the organization of the primitive sinusoid at single-cell resolution.
Basics of the prediction of the risks of CO sub 2 corrosion in oil and gas wells

Criteria are proposed for predicting the risk of CO{sub 2} corrosion in oil and gas wells, based on the detailed analysis of operating experience in 35 distinct fields. Particular emphasis is placed on the conditions corresponding to the absence of significant corrosion. It is shown that two complementary fundamental conditions are necessary for CO{sub 2} corrosion to be observed in a well: a sufficiently high potential corrosivity, conditions favoring rapid localized (mesa type) attack. As a result of this double requirement, several fields are considered as non-corrosive, in spite of their high potential corrosivity, due to the absence of conditions conducive to rapid localized attack. This applies particularly to strongly alkaline formation waters, which have a high pH not withstanding high CO{sub 2} partial pressure. Specific parameters and limiting values are determined for each of these two conditions, distinguishing between the cases of oil and gas wells.
A short & sweet story of CHO

The solid state nuclear magnetic resonance (SSNMR) study of nearly intact plant cell walls along with the computational study of glucose and malonic acid are presented. Previously unassigned chemical shifts are presented for the various carbohydrates in the primary plant cell wall of Arabidopsis thaliana. A continuation of the SSNMR study involved the computational determination of glucose chemical shifts, a model compound for the study of larger carbohydrates. Additional computational studies determined the energy relationship between hydrated tautomers of malonic acid, a commonly occurring atmospheric dicarboxylic acid. In the malonic acid study, agreement between experiment and calculated frequencies verified the presence of the enol form of malonic acid. The development and analysis of a chemical education tool, a quantum chemistry concept inventory, whose aim is to understand misconceptions is also included in this dissertation.
