Authors: Duarte João , Cunha Marco , Carvalho José 
Published: November 2021

Abstract
Portugal, in the continental and insular territory, has raw geological resources in diversity and quality that are materials for the manufacturing industries, particularly linked to the civil construction, architecture and public works with great weight in its exports, revealing to be one big producer of ornamental stones worldwide. In this industry, the presence of discontinuities, grain size, colour, textural anisotropy and porosity are factors that can determine the economic viability of the exploitations. For this, it is important to develop effective prospecting routines that allow the geological/structural fast analysis and economic potential assessment of the massifs and subsequent correct planning and dimensioning of the exploitations. This work intends to model and integrate data from the ground penetration radar (GPR), together with close-range photogrammetry, derived from an Unmanned aerial vehicle (UAV) imagery. The objective is to identify and determine the spatial distribution of the various elements by modelling the acquired data, as well as verifying the feasibility of the technical disassembly option adopted. We have used GPR as it is non-destructive, fast to deploy, survey, process and interpret. The acquired data were processed using the GPR-SLICE, where a 3D final dataset was obtained and interpreted. GPR and photogrammetric model was integrated and interpreted and validated with direct field observations. The model obtained showed in its upper part, an area corresponding to the presence of sludge from the cut of the rock, followed by a strip that corresponds to the oolitic limestone. Further down to the end of the block, the presence of oolitic limestone with crossed stratification is identifiable. There was a textural and structural correspondence between the GPR data and direct field observations. GPR did not reveal any major morphostructural discontinuity, validating the technical option of choosing the places where the cuts were made for their individualization, as the block was cut clean. The GPR and photogrammetry data integration method revealed to be complementary, where results were obtained easily, fast, and with centimeter accuracy. The same methodology presented, revealed to be cheap and effective for both localized studies and optimization of the overall quarry’s extraction plan and design.

Authors: Postnikov D A 
Published: November 2021

Abstract
Floristic composition of terrestrial and aquatic plants in the ecotopes of surface water bodies, Blue Lakes and Lake Biserovo, was studied to assess environmental health of aquatic ecosystems in the Moscow region. The research was carried out both in the field and in the laboratory. Blue Lakes were lacking aquatic vegetation and the dominant synusia of the following plant species was found along the coastal zone: meadow clover (Trifolium pratense L.), meadow bluegrass (Poa pratensis L.), sedge coastal (Carex riparia Curt.), chamomile (Matricaria chamomilla L.), plantain (Plantago major L.), Timothy meadow (Phleum pratense L.). The vegetation cover of Lake Biserovo was patchy: submerged vegetation was most widespread, Canadian Elodea (Elodea canadensis Michx.) was the dominant species. Pure thickets of vegetation were formed only by the common American water plantain(Alisma plantago-aquatica L.), lake cattail (Schoenoplectus lacustris L.), common reed (Phragmites communis Trin.) and sedge coastal (Carex riparia Curt). It should be noted that in all the studied water bodies, the pH of the water area can be classified as very clean: Blue Lakes (7.8), samples from Lake Biserov (8.32). Water samples from Lake Biserova had the highest turbidity (11.5), which was associated with the accumulation of particles of the silt fraction of the reservoir, which began the process of eutrophication, high anthropogenic load. According to the results of a comprehensive assessment (hydrological indicators, calculation of the Mayer index) of the studied samples from the reservoirs, it was concluded that the water area of the Blue Lake had the best environmental status in the Noginsk region.

Authors: Hou Dongpeng 
Published: November 2021

Abstract
As global warming getting more severe in recent decades, the seawater temperature has also increased dramatically, which leads Atlantic fish heading north, so are two important economic fish spcies in Scotland, Scottish herring and mackerel. This paper discusses the impact of temperature change on the two species, and offer improvement methods for the small Scotland-based fishing companies. According the history temperature data in Scotland and the surrounding waters, we use a time series algorithm to predict the temperature range over next 50 years. Then establish a cost equation with parameters based on the relative distance and temperature. We obtain minimum cost from the predicted temperature and the relative distance from shoals. The result shows that in the next 50 years, a portion of the Scottish herring will move first northeast and then north, and the mackerel will move near the coast of Norway. The speed range of fish is obtained from previous model. Furthermore, maximum range of fishing time is obtained under different fish migration speed and fishing vessel speed. The best, worst and most likely case for fishing companies are defined and found. Which are they can fish before 2033 at lowest fish migration speed, they can not fish at the highest speed after 2051, and can not sell fresh fish anymore at 2040 respectively.

Abstract
An experiment to study the effects of supplementation of graded levels of urea or fishmeal on rumen environment and ruminal feed degradation in Bali cows fed low quality tropical grass hay (crude protein, CP = 3.53%) was conducted according to a 5 × 5 Latin square experimental design with five animals and five periods. In each period lasting for 3 weeks, five non-pregnant Bali cows were given ad libitum access to grass hay (G) or supplemented daily with two level of urea, i.e. 38 g (U38) and 74 g (U74), or two levels of fishmeal, i.e. 156 g (FM156) and 312 g (FM312). Supplementation of both urea and fishmeal reduced significantly (P < 0.01) the average rumen pH from 6.89 in G to 6.74 in FM156. Rumen ammonia concentration increased linearly (P < 0.01) with increasing levels of supplementation and the increase was more pronounced with urea than with fishmeal supplementation. Rumen ammonia concentration was significantly higher (P < 0.01) in urea than fishmeal supplemented cows at both levels of supplementation. Ruminal total as well as individual VFAs (Acetate, Butyrate and Propionate) concentrations were not affected by the increasing level of supplementation of both urea and fishmeal. Supplementation improved significantly (P < 0.05) in sacco rumen degradation of DM but not protein. Ruminal DM effective degradability was increased significantly with increasing level of fishmeal supplementation but not with increasing level of urea supplementation. Supplementation of increasing level of both urea and fishmeal improved rumen environment and feed degradability in Bali cows maintained on low quality tropical grass hay with fishmeal was proven to be the better supplement over urea.

Abstract
One Belt One Road (OBOR) is an initiative of collaboration and development that was put forward by China. Moreover, the agricultural production in most of the country members confronted Water scarcity and climate change. In current study it has been used Water Footprint (WF) as tool for measuring water consumption in China and participating country. Thus, this paper aims to understand OBOR from the perspective of WF of agricultural products. On the whole, the results showed that agriculture’s WF in China and OBOR countries increased steadily from about 6.84 trillion m3 in the initial period to about 9.54 trillion m3 in 2018. They also showed that China and India were the largest countries consumed WF which accounted for 76.12% of the total WF used in agricultural production. Furthermore, the WF that has been consumed for agriculture production in China and spanning countries was excessively concentrated on some products. As a whole, green the main water type used in producing agricultural products. Since announcing OBOR initiative in 2013 until now, there is not any remarkable change on GHG emissions that generated from agriculture due to the climate change impacts can be observed only on the long term. WF is a new perspective to explore OBOR. Agricultural trade with China certainly benefits both the countries along OBOR and China from the perspective of WF. The findings of this study is essential as references for better agriculture production structure, and is useful for managing water in China and the nations along the Silk Road, mitigating water scarcities, and wisely distributing the water resources in the various sectors.

Abstract
Changes in economic order in the new normal era have an impact on the marketing and managerial aspects of Micro, Small and Medium Enterprises (MSMEs). Many MSMEs have not yet used digital marketing so that they experienced a significant decline in sales and have not been able to overcome managerial problems. This research method is designed as a survey research with a descriptive approach using narrative analysis tools. The population in this study are MSMEs in West Java selected through cluster random sampling technique. The results of the descriptive analysis show that the managerial aspect has a recapitulation value of the respondents of 1706 (important) and the marketing aspect of 3005 (very important). Manual marketing aspects will be offset by business digitization. Meanwhile, improvements in managerial aspects from the perspective of strengthening human resources and financial records need to be seriously taken by MSMEs actors since both aspects have a significant impact on the sustainability of MSMEs businesses.
