Constant-effort mist-netting has become an increasingly popular tool in longterm monitoring of bird populations. Monitoring programs often assume that variation in the capture rates of adults reflects variation in breeding densities of the sampled population. We test this assumption by comparing annual variation in mist-net capture rates to known variation in breeding densities of four species ...

Background and aims: Development of new air pollution control techniques have always been the main concern of the researchers. The purpose of this experimental study was to investigate the effects of using acoustic fields at high sound pressure levels on the removal of sulfuric acid mist from the air stream. Methods: In this experimental study, an experimental scale agglomeration chamber was...

We fabricated and characterized the material with Mn (10 at.%: atomic percent) doped In3Sb1Te2 (MIST) using co-sputtering and synchrotron radiation, respectively. The MIST thin film showed phase-changes at 97 and 320 °C, with sheet resistances of ~10 kΩ(sq) (amorphous), ~0.2 kΩ(sq) (first phase-change), and ~10 Ω(sq) (second phase-change). MIST did not exhibit any chemical separation or increas...

Oil mist adversely affects the health of workplace workers, and for this reason, regulations on limitation oil-mist exposure workers are becoming stricter. In order to reduce amount oil mist, it is important effectively remove from machine tools. study, collection efficiency according geometry oil-mist-collection cyclone consisting several disks output power rotation speed motor were evaluated....

In a group of patients with mild asthma the inhalation of mist derived from ultrasonically nebulised distilled water caused an increase in cough and a fall in FEV1. Double blind administration for five minutes of sodium cromoglycate (from an original solution containing 30 mg/ml) or atropine (2 mg/ml) by inhalation from a Minineb nebuliser, 30 minutes before the mist challenge, caused a signifi...

Given a graph G, the maximum internal spanning tree problem (MIST for short) asks for computing a spanning tree T of G such that the number of internal vertices in T is maximized. MIST has possible applications in the design of cost-efficient communication networks and water supply networks and hence has been extensively studied in the literature. MIST is NP-hard and hence a number of polynomia...

To date, preterm infants with respiratory distress syndrome (RDS) after birth have been managed with a combination of endotracheal intubation, surfactant instillation, and mechanical ventilation. It is now recognized that noninvasive ventilation (NIV) such as nasal continuous positive airway pressure (CPAP) in preterm infants is a reasonable alternative to elective intubation after birth. Recen...

Red spruce (Picea rubens Sarg.) seedlings were exposed repeatedly at a field site or in a greenhouse~to acidic mist containing the major sulfur and nitrogen pollutants of wet deposition in the eastern U.S.: sulfate alone, nitrate alone or with ammonium ion, and a combination of these ions. Acidities and ion concentrations ranged from below the mean to above the maximum concentration for cloudwa...
