Background: Drying is the most common way to preserve quality of aromatic and medicinal plants. Chosen drying methods can affect on the essential oil content and composition of medicinal plants. Objective: This study aimed to assess the changes in essential oil constitutes of catnip aerial part under various drying methods. Methods: The experiment was performed as the randomized complete ...

Background: In the recent decade, artificial drying has been one of the most important needs of the pharmaceutical industries. In addition, different drying methods have different effects on the quantity and quality of the essential oils produced from medicinal plants. Objective: The main objective of this study was to evaluate the effects of different drying methods (shade and oven drying a...

Microwave oven generates a harmful electromagnetic wave at 2.45GHz of 1000Watts. The generated microwave is confined within the cavity of the oven for efficient heating and secured operation. To prevent microwave leakage through the front glass door, a special construction of Faraday Cage is involved. In this paper, Faraday Cage is replaced with Transparent Frequency Selective Surface Front Doo...

Matlab-SIMULINK based real time temperature control of oven using different kinds of auto-tuning PID (Proportional-Integral-Derivative) methods is presented in this paper. Ziegler Nichols Step Response Method (P,PI), Relay Tuning Method (P,PI) and Integral Square Time Error (ISTE) disturbance criterion (PI) method are used to control temperature of the experiment set. Controller parameters are ...

The main objective of the study was to compare the effects of halogen lamp–microwave combination baking on quality of breads with other baking methods (conventional, microwave and halogen lamp baking). It was also aimed to improve the quality of microwave baked breads by using combination oven. Weight loss, specific volume, firmness and color of the breads were measured as quality parameters. H...

The mVINIS ion source, a part of FAMA installation at Vinca Institute Nuclear Sciences, is able to produce multiple charged heavy beams through the utilization vapors created by process melting solids inside miniature oven (mini-oven). mini-oven that was used previously could only reach maximum temperature 800?C, which far too low for evaporating most metals. For this purpose, higher operating-...

In the frame of unification schemes for radio-loud active galactic nuclei (AGNs), FR I radio galaxies are believed to be BL Lacertae (BL Lac) objects with the relativistic jet misaligned to our line of sight, and FR II radio galaxies correspond to misaligned radio quasars. The Ledlow-Owen dividing line for FR I/FR II dichotomy in the optical absolute magnitude of host galaxy–radio luminosity (M...

The following paper discusses the use of oven temperature profiling as a technique to help maximize the quality of paint and material cure operations, undertaken in the OEM car manufacturing industry. Automotive paint cure application challenges, and recent technical developments are discussed in detail. The Oven Tracker® XL2 system, developed specifically for the automotive paint industry will...
