Concept Towards Segmenting Arm Areas for Robot-Based Dermatological In Vivo Measurements
Authors: Szymanski Mateusz , Van de Sand Ron , Tauscher Esther , Rieckmann Olaf , Stolpmann Alexander 
Published: June 2021

Dermatological in vivo measurements are used for various purposes, e.g. health care, development and testing of skin care products or claim support in marketing. Especially for the last two purposes, in vivo measurements are extensive due to the quantity and repeatability of the measurement series. Furthermore, they are performed manually and therefore represent a nonnegligible time and cost factor. A solution to this is the implementation of collaborative robotics for the measurement execution. Due to various body shapes and surface conditions, common static control procedures are not applicable. To solve this problem, spatial information obtained from a stereoscopic camera can be integrated into the robot control process. However, the designated measurement area has to be detected and the spatial information processed. Therefore the authors propose a concept towards segmenting arm areas through a CNN-based object detector and their further processing to perform robot-based in vivo measurements. The paper gives an overview of the utilization of RGB-D images in 2D object detectors and describes the selection of a suitable model for the application. Furthermore the creation, annotation and augmentation of a custom dataset is presented.

Teamwork as Joint Activity in Sailing
Authors: Forsman Fredrik , Finnsgård Christian 
Published: June 2021

Sailing is a sport and activity that takes a long time both to learn and to master, as much of its competence based knowledge is acquired through experience. Experience based learning is very important time intensive, and the factors for success are often tacit and hidden. Should these success factors become explicit and salient, learning would occur faster and produce obvious competitive advantages.
This research was conducted by embedding on-going research results into two competitive sailing teams racing in different classes, one offshore keelboat racing with a crew of 8, and a one-design Star-class racing yacht with a crew of two. The data collection consisted of observations, interviews, and video recordings. The results were also verified with the crews to catch biases in the analysis process. A jibe, a specific but common maneuver was analyzed from the perspective of Common Ground within Joint Activity.
Maneuvering a competitive offshore sail racer or a previously Olympic Star-class yacht are tasks that fulfill the requirements for Joint Activity. A high level of Common Ground is required for the effective coordination needed in order to perform at a high level and maintain the safety of the crew and equipment.
Breakdowns in the coordination of maneuvers were observed, although they must be recorded on video for higher analysis reliability. To achieve greater validity, more and different maneuvers should be considered within the analysis.
By better understanding the factors for success, sail racing teams can more quickly gain competence and thus competitive advantages.
The research analyzes the teamwork found in sailing from the perspective of Joint Activity and Common Ground and provides insight into how to achieve performance improvements more efficiently.

Published: June 2021

In a field study conducted at the Teaching and Research Farm of Rivers State University PortHarcourt, Nigeria, to examine the ability of vetiver and guinea grasses amended with organic manures in remediation of crude oil polluted soil; soil polluted with Bonny light crude oil at 0 and 2% v/w was subjected to a remediation processes using vetiver (Vetiveria zizanioides) and Guinea grass (Panicum maximum) amended with organic manures for a period of twelve months. Two weeks after pollution, poultry and rabbit manures were applied at 0, 10, 20 and 30 tons per hectare respectively. Vetiver and guinea grasses were planted two weeks later. It was fitted in factorial split plots randomized block design. Results of the study revealed that remediation of the soil with grasses degraded the Total hydrocarbon content (THC) to 23 and 21.2% for vetiver and guinea grass respectively, while the quantity of heavy metals removed from the soil were 28.4% and 25.9% for iron, 37.3 and 32.8% for zinc, 35.8 and 30.8% for lead (Pb) and 23.1 and 38.5% cadmium for vetiver and guinea grass respectively. Amendment of the soil with 30 tons’ /ha organic manures increased the quantity of THC degraded to 70.6% and 67.9% for vetiver and guinea grass respectively while the concentration/quantity of heavy metals removed from the soil increased to 58.4 and 54.7% for Fe, 66.9 and 65.1% for Zn, 69.4 and 66.6% for Pb and 80.8 and 71.2%, in Cd for vetiver and guinea grass respectively. The quantity and concentration of THC and heavy metals degraded in the soil was higher in vetiver than guinea grass plots and in vetiver amended with poultry manure than in guinea grass amended with rabbit manure. There was a significant (P<0.05) difference in uptake of THC and heavy metals in plant tissues between vetiver and guinea grass. Vetiver accumulated more of the contaminants in their tissues than guinea grass. Amendment of the soil with organic manures reduced the uptake of the contaminants (THC and heavy metals) from the plant tissues. Generally, both grasses have the capability to remediate crude oil contaminated soil. Augmentation of the two grasses with organic manures enhanced their capability.

Published: June 2021

The study was carried out to determine the effect of organic and inorganic fertilizers on tomato yield and soil quality. The study was performed in a randomized complete block design consisting of 7 treatments with 3 replications in the research farm, Shaikh Zayed University, Khost, Afghanistan. The fertilizers treatments were T1, organic fertilizer (5 t/ha); T2, organic fertilizer (10 t/ha); T3, urea (150 Kg/ha); T4, urea (200 Kg/ha); T5, mixed fertilizers (organic fertilizer 3 t/ha + urea (100 Kg/ha); T6, mixed fertilizers (organic fertilizer 6 t/ha + urea (70 Kg/ha) and T7 a control. Results indicate that applications of inorganic fertilizers with a combination of organic fertilizers increased tomato yield and improves the nutrient status of the soil. T5 showed the highest yield of tomato and followed by T4 treatment, which were 33.1 and 31.7 t/ha respectively. The lower yield were obtained in T7 and T1 treatments. The highest plant heights (205.0 and 199.0 cm) were obtained in T5 and T4 respectively, while the lowest plant heights were obtained in T1 treatment and followed by T7 treatment. Similarly, we found that a combination of both inorganic and organic fertilizers application also is the best strategy to improve soil nutrients, maintain soil fertility. Soil P2O5 and K2O, where the highest amounts were obtained in T5 and followed by T6, which were 26.5, 22.5 and 44.5 and 41.5 mg/L respectively. The control treatment had the lowest amount of P2O5 and K2O. Therefore, this study suggests that an appropriate amount of organic fertilizer with inorganic fertilizer not only increased tomato yield but also improve soil fertility.
Africa and the Commonwealth: What Relationship Since 1994?
Authors: Faseke Modupeolu 
Published: June 2021

The Commonwealth is a global organisation with some unique and important characteristics that complement other global multilateral organizations. Its peculiarities, most especially its networking and informal qualities, have endeared the organization until recently to her members. In this age of internet in which smartness and alertness are highly valued, some of its traits are now becoming a thing of an anathema, regarded as a cog in the wheel of progress. African continent alone has over thirty percent of Commonwealth membership. This paper examines Commonwealth relations with Africa since 1994 when apartheid ended in South Africa and Africans had a renewed relationship with the organization after both parties had endured a tenuous relationship in the preceding years. The study has the objective of assessing the economic and political gains Africa has derived from membership of the Commonwealth as well as to ascertain whether or not the relationship is mutually beneficial. The essay is qualitative and adopts the historical research methodology, detailing the evolution and progression in Commonwealth’s relationship with Africa during the period of study. The essay complements the use of secondary sources with primary sources. Data was therefore composed of official documents from the |Commonwealth Secretariat as well as documents from some African countries. The study concludes that Africa has benefitted immensely from the Commonwealth since 1994, despite some aspects of its relationship needing improvements. It recommends, therefore, that both parties will have to work towards a symbiotic relationship in order to enjoy a more robust partnership that is effective and impactful in the interest of all.

Aim: The experiment was aimed at identifying the rabi castor based profitable cropping systems for Alfisols of Southern Telangana Zone.
Study design: Split plot design with three replications
Place and duration of study: Regional Agricultural Research Station, Professor Jayashankar Telangana State Agricultural University, Palem, Telangana state, India during rabi season of 2010-11 and 2011-12.
Methodology: The experiment was laid out in a split plot design with five preceding crops (mung bean, fodder jowar, corn, pearlmillet and sesame) in main plots and four nitrogen levels of rabi castor in sub plots (0, 40, 80 and 120 kg N ha-1). The growth parameters, yield attributes, seed yield, water use efficiency and economics were studied.
Results: The results showed that among different proceeding crops evaluated that significantly higher castor seed yield and castor equivalent yield were obtained when rabi castor was preceded by corn (1973 and 2931 and kg ha-1) and mung bean (1868 and 2696 kg ha-1) as compared to that of sesame (1672 and 2207 kg ha-1), pearl millet (1823 and 2199 kg ha-1) and fodder jowar (1783 and 2154 kg ha-1). However, higher total system gross returns (Rs. 1,04,118 ha-1) and net returns (Rs. 52,462 ha-1) were accrued when rabi castor was grown after corn only, but, a higher B:C ratio was realized due to mung bean as a preceding crop (2.12). Though castor during rabi season responded similarly to 80 and 120 kg N ha-1 in terms of castor seed yield (2275 and 2381 kg ha-1) and castor equivalent yield (2887 and 3013 kg ha-1), application of 120 kg N ha-1to castor resulted in accruing of higher system net returns (Rs. 60,638 ha-1) and B:C ratio (2.27). However, the results of interaction further showed that rabi castor preceded by mung bean with the application of 80 kg N ha-1 was found profitable (Rs. 75,573 ha-1). It was closely followed by corn-castor system (Rs. 73,289 ha-1).

The experimental field study was conducted at Borlaug Institute for South Asia (BISA) Research Farm, Lakhanwada, Jabalpur, Madhya Pradesh, India to evaluate the soil carbon fractions (very labile, labile, less labile and non-labile or recalcitrant carbon) in different land use practices with soil depths under cropping systems in Vertisols after harvest of Kharif and Rabi season crops of year 2015-16 and 2016-17. The experiment was conducted under Split plot design considering land use practices as main plot treatments [L1: Uncultivated, L2: rice-wheat system with conventional agriculture (CT), L3: rice-wheat system with conservation agriculture (CA), L4: soybean-wheat system with CT, L5: soybean-wheat system with CA, L6: maize-wheat system with CT and L7: maize-wheat system with CA] and depth (0-5 cm, 5-15 cm and 15-30 cm) as sub-plot treatments replicated thrice. Very labile carbon fraction was obtained highest in L3 (rice-wheat system with CA) and lowest under L6 (maize -wheat system with CT) treatment after harvest of Kharif and Rabi season crops during 2015-16 and 2016-17and it was significantly higher at 0-5 cm soil depth than those in 5-15 cm and 15-30 cm soil depths. Similar trends were also obtained in case of labile, less labile and non-labile fraction of carbon i.e. the applied land use practices had significant effect on all the carbon fractions under study and found to be maximum under L3 (R-W system with CA) and minimum in L6: (M-W system with CT) treatment after harvest of both the season crops during both years of experiment. Whereas, the interaction effect of land use practices and soil depths on the carbon fractions was found statistically non-significant during both the seasons and years.

Published: June 2021

The present study aimed to use chemically activated rice husk biochar as an adsorbent for the removal of heavy metals from an aqueous solution. A series of the Rice husk biochar (RHB) samples were produced at different temperatures, as follows: 300, 400, 500, 600, and 700℃ for 2 hours each through pyrolysis process in Dalhan Scientific Muffle Furnace. The chemically treated rice husk biochar synthesized at 500℃ was used as potential char for removal of Cu(II) and Pb(II) from aqueous solutions. The sorption of these metal ions from an aqueous solution was determined after adsorption using Flame Atomic Absorption Spectrophotometry (AAS). The Shimadzu IR Affinity Fourier Transform Infra-Red Spectroscopy (FT-IR) was used for the characterization of rice husk char and it revealed the presence of OH, C=O, and COO- bonds which are responsible for heavy metal ions adsorption through chemisorption. The effect of adsorption parameters was determined that is; pyrolysis temperature which was found to be 500℃, the optimal contact time for the metal ions Cu (II) and Pb (II) was found to be 60 minutes, the optimum dosage was 0.250 g and optimum initial concentration was 2 mg/l. The kinetics were tested against pseudo-first order and pseudo-second order model as well Langmuir and Freundlich isotherms. Cu(II), adsorption process followed Pseudo-second order kinetics with regression coefficient (R2) 0.9942 and Langmuir isotherm model with R2 0.9895. For Pb(II), adsorption capacity followed Pseudo-second order kinetics with regression coefficient (R2) 0.99991 and Freundlich isotherm model with R2 0.96675 optimum equilibrium adsorption capacity of 0.5274 mg/g.
