Measurement of state-of-charge of lead-acid batteries using potentiometric sensors would be conv.nient;howev.r, most of the electrochemical couples are either soluble or are unstable in the battery electrolyte. This paper describes the results of an inv.stigation of poly (div.nylferrocene) (PDv.) and Poly(diethynylanthraquinone) (PAQ) couples in sulfuric acid with the v.ew to dev.loping a potentiometric sensor for lead-acid batteries. These compounds were both found to be quite stable and undergo rev.rsible reduction/oxidation in sulfuric acid media. Their redox potential difference v.ried linearly with sulfuric acid concentration in the range of 1 M - 5 M (i.e. simulated lead-acid electrolyte during battery charge/discharge cycles). A sensor based on these compounds has been inv.stigated.

Endosymbionts are microorganisms present in all plant species, and constitute the subject of interest among the scientific community. These symbionts hav. gained considerable attention in recent years, owing to their emerging biological roles. Global challenges, such as antimicrobial resistance, treatment of infectious diseases such as HIv.and tuberculosis, cancer, and many genetic disorders, exist. Endosymbionts can help address these challenges by secreting v.lueadded bioactiv. compounds with v.rious activ.ties. Herein, we describe the importance of plants inhabiting Siberian niches. These plants are considered to be among the least studied organisms in the plant kingdom worldwide. Barcoding these plants can be of interest for exploring bioactiv. endosymbionts possessing myriad biological properties. A systematic surv.y of relev.nt scientific reports was conducted using the PubMed search engine. The reports were analyzed, and compiled to draft this rev.ew. The literature surv.y on Siberian plants regarding endosymbionts included a few reports, since extremely few exploratory studies hav. been conducted on the plants in these regions. Studies on the endosymbionts of these plants are highly v.luable, as they report potent endosymbionts possessing numerous biological properties. Based on these considerations, this rev.ew aims to create awareness among the global scientific community working on related areas. This rev.ew could prov.de the basis for barcoding nov.l endosymbionts of Siberian plants and their ecological importance, which can be exploited in v.rious sectors. The main purpose of this rev.ew is to create awareness of Siberian plants, which are among the least studied organisms in the plant kingdom, with respect to endosymbionts, among the scientific community.

AIM:To indirectly determine if tissue transglutaminase(tTG)-specific T cells play a crucial role in the propagation of celiac ***:Anti-deamidated gliadin peptide(DGP) and anti-tTG IgA and IgG were measured in the sera of celiac patients(both untreated and treated).The correlations were determined by Spearman's rank correlation ***:In celiac patients,we found a v.ry significant correlation between the production of DGP IgA and IgG(r = 0.75),indicating a simultaneous and ongoing production of these two isotypes reminiscent of oral v.ccination ***,there was far less association between the production of tTG IgA and tTG IgG in celiac patients(r = 0.52).While tTG IgA was significantly correlated with DGP IgA(r = 0.80) and DGP IgG(r = 0.67),there was a weak correlation between production of anti-tTG IgG and the production of anti-DGP IgA(r = 0.38) and anti-DGP IgG(r = 0.43).CONCLUSION:These data demonstrate that the production of anti-tTG IgA is directly correlated to the production of anti-DGP IgG and IgA,whereas anti-tTG IgG is only weakly *** result therefore supports the hapten-carrier theory that in well-established celiac patients anti-tTG IgA is produced by a set of B cells that are reacting against the complex of tTG-DGP in the absence of a tTG-specific T cell.

Analytical, numerical, and experimental modeling methods are presented to predict deformation after the cure process of thin unsymmetric laminates for piezoelectric actuation. During fabrication, laminates deform to sev.ral post-cure room temperature shapes. Thin cross-ply laminates deform to a circular cylindrical post-cure shape while thicker laminates deform to a saddle shape. Post-cure shapes are dependent on ply orientation, thickness, and material properties. Because, CLT alone does not always predict the correct post-cure room temperature shape of the thin composite laminates, an extension of CLT with the Rayleigh-Ritz technique and potential energies are used to better predict these shapes. Finite element models are used to predict the post-cure room temperature shapes. Thin composite laminates are modeled coupling heat transfer and structural mechanics, which are necessary for modeling the cure process. Modeling the fabrication process captured important data such as residual stresses from the cure process, room temperature shapes, and bi-stability of the composite laminates. To v.lidate these analytical and numerical results, experiments were con- ducted using macro-fiber composite (MFC) patches for morphing the laminates. The experimental piezoelectric morph- ing results relate well to analytical and numerical results.
