The radio operation in wireless sensor networks (WSN) in the Internet of Things (IoT) applications are the most common source for power consumption. However, recognizing and controlling the factors affecting radio operation can be valuable for managing the node power consumption. ContikiMAC is a low-power Radio Duty-Cycle protocol in Contiki OS used in WakeUp mode, which is a clear channel assessment (CCA) to check radio status periodically. The time spent to check the radio is of utmost importance for monitoring power consumption. It can lead to false WakeUp or idle listening in Radio Duty-Cycles and ContikiMAC. This paper presents a detailed analysis of radio WakeUp time factors of ContikiMAC. Then, we propose lightweight CCA (LW-CCA) as an extension to ContikiMAC to reduce the percentage of Radio Duty-Cycles in false WakeUps and idle listenings by using dynamic received signal strength indicators (RSSI) status check time. The simulation results in the Cooja simulator show that LW-CCA reduces about 8% energy consumption in nodes while maintaining up to 99% of the packet delivery rate (PDR).

The present paper describes the synthesis of new palladium–oxazoline complexes in one step with good to high yields (68–95%). The oxazolines were prepared from enantiomerically pure α-aminoalcohols. The structures of the synthesized palladium complexes were confirmed by NMR, FTIR, TOFMS, UV–visible spectroscopic analysis and X–ray diffraction. The optical properties of the complexes were evaluated by the determination of the gap energy values (E g) ranging between 2.34 and 3.21 eV. Their catalytic activities were tested for the degradation of Eriochrome Blue Black B (a model of azo dyes) in the presence of an ecological oxidant (H2O2). The efficiency of the decolorization has been confirmed via UV–visible spectroscopic analysis and the factors affecting the degradation phenomenon have been studied. The removal of the Eriochrome reached high yields. We have found that the complex 9 promoted 84% of color elimination within 5 min (C 0 = 30 mg/L, T = 22 °C, pH 7, H2O2 = 0.5 mL) and the energetic parameters have been also determined.

Definition Of

The amylosecontents in starch is one of its qualitycharacteristics. Generally it is a specific sign of astarch-containing material and the starch received from it. Physical and chemical properties of starch and its use in the national economy depend on it. In small quantities the amylose is received by starch fractionating. It is the difficult and expensive technology. Selectors carry out research workson creation of new varieties of potatoes, grain and leguminous crops with the increased content of amylose in starch. They need techniques of definition of amylose in different types of raw materials. But before developing a technique, it is necessary to investigate optical properties of this or that type of starch and the components making it. It showed from researches, different types of starchhad differentoptical properties of itscomponents. For example, the technique developed for definition of amylose in corn starch isn't acceptable for its definition in starch of triticale and wheat. Earlier we studied properties of iodine polysaccharides of corn and triticale starches and factors affecting the optical properties of iodine polysaccharides. In this work it was investigated the influence of amylose, concentration of iodine and potassium iodide at KI:I from 3 to 15 on an optical density of wheat iodine polysaccharidessolutions. It is established that the iodine amylose of wheat has a maximum at 600 nanometers, an iodine amylopectin has at 565 nanometers. Spectra of wheatpolysaccharides differ in value of an optical density ?max and a form of curves from related polysaccharides of triticale. Concentration of an iodine in the studied solution has to be equal 0.6 mg/cm3, and a ratio of potassium iodide to an iodine has to be 5.
