Abstract: The present work introduces a new solar selective absorber coating (SSAC) for the receiver tube of Concentrated Solar Power (CSP) systems, proposing silver as an infrared reflector application at 550 °C. In past, Italian National Agency New Technologies, Energy and Sustainable Economic Development (ENEA) has developed SSACs suitable applications °C, featuring absorbers based on graded multilayer cermet WN-AlN W-Al2O3 tungsten. Although these coatings ensured properly stable...

This article includes a review of theoretical and empirical models educational outcomes to identify student attitudes behaviors that researchers have hypothesized influence academic achievement. A model is proposed the relationships between specific enablers (motivation, interpersonal skills, engagement, study skills) Structural equation modeling used test fit this for two samples elementary students. The results these analyses indicate prior achievement skills motivation, which in turn...

Seventy-one patients with proven subacute (nonsuppurative) thyroiditis have had determinations of antibody to a variety viruses during the course their illnesses. While 58 these showed some circulating viral antibody, in 26 antibodies did not change titer through 4-fold dilutions illness and thus were considered "significant." In 32, "significant" (at least 4-fold) changes illnesses, suggesting recent infection. The period rising titers was usually missed since generally seen early direction...

There is considerable evidence to suggest that the organspecific autoimmune endocrinopathies are primary disorders of lymphoid system. Although proof not complete, basic genetic defect in each condition may be one immune surveillance, is, a suppressor "T" lymphocytes. Combinations two or more these conditions due concurrence specific defects control, as well random appearance appropriate self-directed "forbidden" clones In this concept, there no need for antigenic alteration (only...

Several reports have been published on the anti-TSH receptor antibody in putative autoimmune thyroid disorders using a radioreceptor assay. We carried out correlative studies between ability of serum immunoglobulins to displace radiolabeled TSH from plasma membrane [TSH-displacing activity (TDA)] and that actual stimulation human gland [human thyroid-stimulating (hTSA)] Graves' other diseases control subjects. TDA was assayed by use radioligand technique, while activation adenylate cyclase...

A radioreceptor assay for human thyroid stimulators has been employed in various groups of patients. The ability Ig to displace the labeled TSH from receptors is referred as "TSH displacement activity (TDA)." In active Graves' disease, TDA was above normal 76% cases, and remaining patients, it 76th percentile, suggesting that thyroid-stimulating (TSIg) may have present all but not always demonstrable by this method. Significant found persons or toxic nontoxic nodular goiters. It also...

We examined the expression of HLA-DR antigen induced by mitogen, mitogen-free supernatants from mitogen-stimulated peripheral blood mononuclear cells (PBMC), or autologous and allogeneic PBMC on thyrocytes cultured for 1–2 weeks (precultured) before addition stimulant. Leucoagglutinin (LAG) concanavalin A, but not lipopolysaccharide normal subjects (NC) patients with Graves' disease (GD) Hashimoto ' ls thyroiditis (HT). The degree DR LAG was significantly less in GD than NC thyrocytes. This...

This volume consists of a series chapters by different authors on various aspects autoimmune endocrine diseases, edited well-known figure in the field thyroid autoimmunity. The contributors vary considerably their treatment subject matter, comprehensiveness, and handling other viewpoints. They are, however, all experts fields, with interesting sometimes controversial perspectives, book makes reading is worthwhile contribution. Chapter 1, Duncan Adams, pioneer seminal contributor to our...

The involvement of cell-mediated immunity in the pathogenesis Graves' disease (GD) and Hashimoto's thyroiditis (HT) was investigated by employing a modified migration inhibition factor test using preparations isolated T-lymphocytes. T-lymphocytes from patients with GD HT response to crude human thyroid antigen significantly inhibited compared normal subjects. This organ specific. When were mixed or Tlymphocytes ratios varying 1:9 1:1, activity abolished, but not abolished when two different...

ABSTRACT The production of migration inhibition factor (MIF) by sensitized lymphocytes in the presence specific antigen is an accepted vitro test cell-mediated immunity (CMI). MIF has been performed patients with untreated Graves' disease (6 hyperthyroidism and exophthalmos, 9 but no Euthyroid Ophthalmic disease) normal subjects, against human retroorbital muscle (RMA), thyroid (TA) other organ antigens. Human thyrotrophin (TSH) was also used as antigen, either alone, or after incubation...

The status of thyroid function during the course subacute thyroiditis has been assessed in 56 cases, 21 which received no specific therapy to modify natural disease. In 11 very severe cases initial extensive inflammatory necrosis presumably led flooding body with hormone, thus producing symptoms hyperthyroidism a high level serum protein-bound iodine (PBI), an increased basal metabolic rate and profound depression thyroidal I131 uptake virtually zero. Following acute phase patient passed...

Serum total triiodothyronine (T3) concentrations have been determined in pregnant women and newborn infants. The serum T3 was similar to that found nonpregnant control persons, contradistinction the marked elevation of thyroxine (T4) pregnancy (due increased binding globulin). Cord blood samples showed values be maternal normal values. administration varying doses (50–300 μg/day) subjects for as long 3 weeks before parturition caused a rise both values, indicating placental transfer T3....

.This study examined academic and social impairments of 6- to 11-year-old children with attention deficit hyperactivity disorder (ADHD; n = 101) versus other referred without ADHD (n 53) controls 24). Parent teacher ratings showed significantly lower performance functioning for compared controls. Children scored than on standardized tests reading/language, mathematics, written language, mathematics. In multiple regression analyses, cognitive ability accounted the most variance in predicting...
