UNLABELLED From 1995 to 2004, in Genoa, Italy, daily concentrations of twelve polycyclic aromatic hydrocarbons (PAHs) were measured in particulate phase (PM10), around a coke oven plant in operation from the 1950s and closed in 2002. The study permitted to identify the coke oven as the main PAH source in Genoa, causing constant exceeding of benzo(a)pyrene (BaP) air quality target (1.0 ng/m3) in...

This study aimed to determine the phytochemical potential of belimbing wuluh leaves (Averrhoa bilimbi L.) as natural antibiotic candidates for broilers. Belimbing were processed by drying them in direct sunlight, indirect and an oven at 60 °C. The obtained data descriptively analyzed. parameters measured screening test Escherichia coli antibacterial test. results starfruit leaves, sunlight meth...

Saat ini tepung porang (Amorphophallus muelleri Blume) telah menjadi primadona pasar global, karena sumber potensial glukomanan yang diaplikasikan di industri pangan, farmasi dan Kesehatan. Namun kualitas sangat dipengaruhi oleh beragam umbi, penanganan pasca panen cara memproses. Disamping itu, umbi tidak dapat dikonsumsi secara langsung kandungan oksalat. Sehingga untuk mencapai standar kuali...

Fresh mint perishable to extend shelf-life drying is a common practice among people. The application proper method essential preserve its Lack information on characteristic that could be design dryers major bottleneck processing. This accounts poor colour, taste, f...

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-...
