While testing a Strömgren spectrophotometer attached to the 1.5-m telescope at the San Pedro Mártir observatory, Mexico, a number of A-type stars were observed, one of which, HD 207331, presented clear indications of photometric variability. CCD photometric data acquired soon after, confirmed its variability. In order to determine its pulsation behaviour more accurately, uvby differential photo...

Working memory (WM) has been hypothesised to be impaired in attention-deficit/hyperactivity disorder (ADHD). However, there are few studies reported on tests measuring visuo-spatial WM (VSWM) in ADHD. Some of these studies used paradigms including episodic memory, others only used low memory loads. In the present study we used a VSWM test that has not been used previously in ADHD research. The ...

We analyze a set of three PT-symmetric complex potentials, namely harmonic oscillator, generalized Pöschl-Teller and Scarf II, all of which reveal a double series of energy levels along with the corresponding superpotential. Inspired by the fact that two superpotentials reside naturally in order-two parasupersymmetry (PSUSY) and second-derivative supersymmetry (SSUSY) schemes, we complexify the...

Many forms of thyroid diseases have been classified under autoimmune disease. These include hyperthyroidism or commonly known as Grave’s disease, and hypothyroidism identified Hashimoto’s thyroiditis. nutritional elements linked to the function gland any disturbance in these can lead development relevant diseases. The most important iodine, iron, selenium, zinc, soy. In this current manuscript,...

Systemic juvenile idiopathic arthritis (JIA) is the most severe category within the group of arthritis which are classified under the umbrella term of JIA. Systemic JIA has been considered a therapeutic orphan until few years ago when the disease was treated primarily with corticosteroids with the known side effect especially on child growth. More recently the availability of new treatment moda...

Gas-chromatographic analysis of the volatile compounds in the headspace of cultures inoculated with sewage sludge indicated phosphine production over a period of several days, a reaction which is clearly microbiologically mediated. The amounts of phosphine recovered from 40-mL specimens sewage sludge enrichment were in a pg-range of 5 to 100 in the presence of glucose as carbon source and phosp...
