A Very Low Frequency (VLF) Synchronizing System

Biological Effects of Very Low Frequency (VLF) Atmospherics in Humans: A Review

Ð The living organism is constantly affected by natural electromagnetic influences covering a wide range of frequencies and amplitudes. One of these influences, with frequencies in the very low frequency (VLF) range, (1-100 kHz) is represented by a phenomenon called VLF-atmospherics or VLF-sferics. Sferics are very short, weak, and dampened electromagnetic impulses generated by atmospheric disc...

two dimensional modeling of very low frequency (vlf) data along a profile across north tehran fault in shahran region, iran

two dimensional single frequency scalar vlf data modeling has been studied in this research. vlf method is one of the electromagnetic investigation methods. radio frequency waves are used for investigation of conductive deposits (paal, 1968). synthetic modeling and inversion of single frequency and multiple frequencies of vlf signals was done by oskooi (2004) for two dimensional simple structur...

Frequency of Thyroid Function Disorders among a Population of Very-Low-Birth-Weight Premature Infants

Background: Thyroid function disorders, particularly congenital hypothyroidism (CHT), are important endocrine dysfunctions associated with permanent morbidities. CHT is more prevalent among preterm low-birth-weight neonates compared to term infants with normal weight. Methods: This prospective cohort study was conducted on 126 very-low-birth-weight (VLBW) neonates referred to the neonatal inten...

Very low HbA1C, is it a problem?

Dear Editor An important problem to manage diabetes mellitus is controlling the patients` blood glucose. Fluctuation of blood glucose results in molecular biochemistry change and can result in unwanted diabetic complications (1). In clinical practice, hemoglobin A1C (HbA1C) is a common useful laboratory test to follow-up patients with diabetes (2). Sometimes, an unexpecte...
