Abstract
A new interference suppression algorithm based on the spatial and temporal characteristics of ocean surface current data has been proposed in this paper. A three days’ ocean surface currents measured by two High Frequency Surface Wave Radar (HFSWR) systems located at Fujian Province is used to test the validity of the algorithm. The results show that interference suppression method proposed in this paper has effectively suppressed the interference signal, after interference suppression, the shape of the current field is well kept, and the mean RMS reduction is 6.88 cm/s, the max RMS reduction is 23.26 cm/s, the mean correlation coefficient promotion is 12.82%, the max correlation coefficient promotion is 64.04%.
Sideways crab-walking is faster and more efficient than forward walking for a hexapod robot
Authors: Chen Yang , Grezmak John E , Graf Nicole M , Daltorio Kathryn A 
Published: April 2022

Abstract
Articulated legs enable the selection of robot gaits, including walking in different directions such as forward or sideways. For longer distances, the best gaits might maximize velocity or minimize the cost of transport (COT). While animals often have morphology suited to walking either forward (like insects) or sideways (like crabs), hexapod robots often default to forward walking. In this paper, we compare forward walking with crab-like sideways walking. To do this, a simple gait design method is introduced for determining forward and sideways gaits with equivalent body heights and step heights. Specifically, the frequency and stride lengths are tuned within reasonable constraints to find gaits that represent a robot’s performance potential in terms of speed and energy cost. Experiments are performed in both dynamic simulation in Webots and a laboratory environment with our 18 degree-of-freedom hexapod robot, Sebastian. With the common three joint leg design, the results show that sideways walking is overall better (75% greater walking speed and 40% lower COT). The performance of sideways walking was better on both hard floors and granular media (dry play sand). This supports development of future crab-like walking robots for future applications. In future work, this approach may be used to develop nominal gaits without extensive optimization, and to explore whether the advantages of sideways walking persist for other hexapod designs.

Abstract
To meet the objectives, the solid urban waste generated in Naranjillo is characterized and quantified and its adequate management is proposed. For this purpose, the methodology of the United Nations Urban Management Program, the calculation of the sanitary landfill through the guide for the design, construction, and operation of manual sanitary landfills, by Jorge Jaramillo, was used. The study determined 91.14% of usable solid waste and 8.86% of unusable solid waste whose final disposal should be in the sanitary landfill. 75.72% are organic waste that have the biological treatment in the composting plant; 15.42% of inorganic solid waste should be recycled through classification in the manual segregation plant, both components should enter the economic cycle. The volume of the landfill calculated until 2030 corresponds to 1555.80m 3 for a projected population of 4695 inhabitants in that year: with an urban solid waste production of 1575.86 Kg/day. The municipality of the district of Luyando by applying the proposed model of urban solid waste will improve the quality of life of its inhabitants by avoiding the contamination of water, soil, air, and the deterioration of the landscape.
Indoor Air Purification by Plants Experiment and Its Arithmetic Mean and Regression Analysis
Authors: Lin Chia-Hui 
Published: April 2022

Abstract
Plants can purify indoor air quality; in particular, plant transpiration can facilitate indoor air movement, purify air by removing pollutants effectively, and provide clean indoor air. In this study. The first and second stages mainly focused on selecting plants with superior performance in the indoor spaces. In the final stage, the effects of different arrangements of grow lights and air conditioners were investigated. The arithmetic mean and regression analysis results demonstrated that the plants illuminated with grow lights had superior performance. Plants that performed photosynthesis and transpiration simultaneously could lower the average temperature, increase indoor humidity (to make up for the lack of cold room humidity), and lower CO2 concentration. Our results demonstrated that placing plants together at a location across the air conditioner and under grow light illumination afforded the most effective indoor air purification and CO2 removal.

Published: April 2022

Abstract
The purpose of the research was to carry out a comparative assessment of the quality of grilled cheese (halloumi) obtained from the milk of cows of three genotypes. The cheese was prepared according to the Cypriot halloumi technology, but instead of sheep or goat milk, they used cattle milk. The milk of red-mottled cows differed from the milk of other breeds with a higher content of skimmed milk solids, protein and fat. Grilled cheese made from milk of cows of all genotypes, manufactured using hallumi technology, meets the requirements of GOST R 52686-2006 and is bold (Simmental cows) or fat (black-mottled and red-mottled breeds). Grilled cheese made using hallumi technology from the milk of red-mottled cows has an average moisture content, an average density, a higher yield and is more saturated with lactic acid than cheese from the milk of Simmental and black-mottled breeds. Halloumi grilled cheese made from milk of cows of all three genotypes is suitable for roasting within 6 days from the date of production.
Assessment of the integrated palinotoxic effect of ecotoxicants on microhametophyte Vitis vinifera L.
Authors: Ibragimova E E , Manankova O P 
Published: April 2022

Abstract
The article presents information of the study of the complex effects of heavy metals and residual dose of pesticides on the male generative organs of populations of Vitis vinifera L. growing in agricultural areas of Crimea with varying degrees of pollution and located along highways with different road traffic. The control possibility is populations growing up on plantations which located at a considerable distance from highways. In the soil samples of these areas, residual amounts of pesticides (baileton, BI-58, insegar) were found, the content of which didn’t exceed the established sanitary and hygienic standards. A microgametophyte test of V. vinifera L. populations growing in agricultural areas whose soils are contaminated with heavy metals and pesticide residues revealed reduced production of fertile pollen compared to the control zone and background, significantly decreasing with increasing concentrations of ecotoxicants. Morphometric analysis of abortive pollen grains revealed an increase in their size, with the largest number found in more polluted areas. Increased production of large sterile pollen may indicate an adverse effect of heavy metals and pesticides on the generative organs of grapes and microsporogenesis occurring in them. It was found that pollutants in the background and in the Bakhchisarai district (low load) had a mildly toxic effect, in Alushta (medium load) and Simferopol district (high load) – a medium toxic effect of microgametophyte V. vinifera L. Thus, heavy metals and pesticide residues can form more toxic combine.
