Published: March 2024

Byers Peninsula (62°34’-62°40’S-60°54’61°13’W), 60 km2 in size, is considered one of the
largest ice-free areas in Antarctica. Since 2006, the Spanish Polar Program has taken part in a large
number of environmental studies involving effects of climate changes, limnology and microbiology,
live cycles, but not albedo. Surface albedo is one of the key physical parameters in the surface energy
budget of polar regions. Most of Antarctica is covered by ice sheets; only about 0.44% of the area is
permanently ice-free. However, in maritime Antarctica, the ice-free areas, corresponding to small
islands, peninsulas, and coastal beaches, account for about 3% of the territory. To incorporate the
contribution of these areas into global albedo models, it is necessary to relate the soil properties of
the ice-free areas to the surface albedo response. Also, mapping soil properties and albedo have and
special interest in these ice-free areas. Image classification using machine learning methods trained
with georeferenced soil data could be useful for mapping soil properties and albedo in multispectral
optical satellite images. A shallow neural network implemented using the Keras Python module was
used to define and train models of soil properties using 15 explanatory variables corresponding to
bands and spectral indices of a Sentinel image and a population of 49 soil samples taken from the
top 5 centimeters of the soil profile. The soil samples were analyzed in the laboratory and a spectral
library in the Vis-Nir range (350-2500 nm) was created. The albedo of the samples was integrated
from the ADS spectra. At the same time, a linear regression model of albedo using the soil properties
as explanatory variables was performed. The R2 fit of this new model was about 0.82 and the error of
estimation was 4.1. The model was extended to the entire Byers Peninsula using the ML soil property
models as explanatory variables. The RMSE of the extended models increased up to 8.2. We think
that the main cause of this increase (2.6 points) is related to the error propagation, phenomenon due
to the use of models as explanatory variables. However, another important part of the error increase
could be due, among other reasons, to the use of an image that, although corrected, is not completely
free of clouds.

Authors: Hamamoto Sora , Hirogaki Toshiki , Aoyama Eiichi , Fujiwara Kazuna , Taketani Masashi
Published: March 2024

Carbon fiber reinforced plastic (CFRP) is a lightweight material with exceptional mechanical properties such as high specific strength, high specific modulus, and retained fatigue strength. It exhibits outstanding characteristics derived from its carbon content such as electrical conductivity, low thermal expansion, chemical stability, and high thermal conductivity. These unique features make CFRP a highly versatile material. It can be extensively used across various industries, offering advantages over steel, aluminum, and glass fiber reinforced plastic. Moreover, its anisotropic nature allows for innovative design possibilities, providing different mechanical properties for different fiber orientations. The increasing demand for CFRPs, particularly in the aerospace and automotive industries, is attributed to their high reliability and design flexibility. Consequently, the requirement for efficient and high-quality CFRP processing techniques has led to numerous studies focusing on trimming and hole drilling of CFRP parts. Previous research has also highlighted the significant impact of processing temperature on the quality of CFRP and other fiber reinforced plastics, such as aramid fiber reinforced plastic. However, many existing reports are limited to specific processes such as trimming or hole drilling, without addressing broader concerns such as tool wear, burrs, fiber damage owing to heat, or the lack of multi-purpose cutting tools suitable for CFRP when considering tool costs. In addition, the aerospace industry demands precise hole drilling for thousands of holes, facilitating assembly with rivets or screws; this requires high-precision hole drilling processes. To address CFRP hole drilling challenges, this study proposes and develops a cBN electroplated ball end mill to enable an efficient and high-quality hole drilling in CFRPs. As machining demands evolve with diverse workpiece materials, technological innovations are continuously being sought in hole drilling processes, exploring alternatives beyond conventional drilling such as employing end mills and enhancing tool functionality. In this study, we employed a ball end mill and helical interpolation motion to tackle CFRP hole drilling. The delamination occurring at the exit side of the drilled holes was investigated using strain gauges. Additionally, finite element analysis was employed to compare and analyze experimental results, leading to guidelines for an efficient and high-quality hole-drilling approach that balances productivity and workpiece integrity. We achieved high-efficiency hole drilling while maintaining the quality by adjusting the cutting parameters under conditions that prevent delamination. The proposed cBN electroplated ball end mill offers promising potential for advancing CFRP processing methods, addressing the growing demand for this exceptional material in various applications.
Influence of Abrasive Grain Protrusion on High-Quality Machining of Cemented Carbide Using PCD Ball End Mills
Authors: Katahira Kazutoshi , Morita Shinya
Published: March 2024

In this study, cemented carbide was machined to a high quality using polycrystalline diamond (PCD) ball end mills characterized by various surface textures. The effect of the surface texture of the tools on the machining characteristics was studied using two types of PCD tools featuring abrasive diamond grains at various protrusion heights. In addition, a single crystal diamond tool with the same shape as that of the PCD tool was fabricated, and the experiment was repeated to study the differences in machining characteristics. The polished PCD tool yielded a high-quality machined surface with an average surface roughness of 1 nm. The polished PCD tool yielded superior sample surface roughness compared to the PCD tool for feed rates of 10–500 mm/min. The use of a polished PCD tool enables the efficient elimination of material through plastic flow, leading to the attainment of a high-quality machined surface while preventing the adhesion of materials on the tool surface. A single crystal diamond tool can also be used for machining cemented carbide within a feed rate range of 10–200 mm/min; however, its performance is inferior to that of a polished PCD tool. Experiments confirmed that the polished PCD tool was the most effective among the tested tools for the precision machining of cemented carbide.

Authors: Hiramitsu Tatsuhiro , Miyake Yuuki , Seki Hiroaki , Tsuji Tokuo
Published: March 2024

Air cylinders are actuators that slide a piston inside cylinders by applying air pressure. We propose an air-cylinder-type artificial muscle that can be flexibly bent by using a flexible tube for the cylindrical part. The actuator output was a string connected to a piston. When the air-cylinder-type artificial muscle bends, the inner wall of the tube and the string come into contact, causing output fluctuations owing to friction. In this study, we investigated the output when an artificial muscle was bent. After describing the structure of the air-cylinder-type artificial muscle, the measurement results of the resistance force at each part of the actuator are presented. A theoretical output inspired by the capstan equation was derived, and its validity was verified by comparison with experimental results.

The aim of the study was to determine the effect of FABA growing media and cow manure on the growth and yield of mustard greens (Brassica Juncea L.). This research was carried out on the land of the Bengkulu Muhammadiyah University. The design used was a factorial complete randomized design (CRD) with 1 factor, namely factor A1 = 4:1 (Faba 100 %), A2 = 3:1 (Faba 75 % + Manure 25%) A3 = 2:2 (Faba 50 % + Manure 50 %), A4 = 1:3 (Faba 25 % + Manure 75 %), A5 = 0:4 (Manure 100 %). Based on the tested level of one of these factors, 20 treatment combinations were obtained. Each experimental treatment contained 5 plants so that there were 100 plants to be observed in this study. The results of this study showed that there was an interaction between the treatment of Faba growing media and cow manure on plant height, leaf width, leaf length, number of leaves and dry weight of mustard plants. The best results were in the treatment interactions between A1, A2, A3, A4, and A5, the best growth was in the A3 and A4 treatments. Because, in the 100% and 75% Faba treatment, plant growth was not good and there were several plants with yellowing leaves. This indicates that the use of Faba planting media must be balanced with organic matter so that plant growth is maximized.

Authors: Hadi Rafah Abdul
Published: March 2024

A theoretical study by using computer model is presented to study the energy characteristics of the vibrational – rotational levels as a function of the vibrational and rotational quantum number, respectively. The calculations were based on the basis of a multilevel model taking into account the non-equilibrium population of the rotational levels. The computational investigation has been performed to examine the vibrational-rotational characteristics of some hydrogen halides chemical laser molecules. This program takes into account the various molecules of chemical lasers such as, Hydrogen Fluoride (HF), Deuterium Fluoride (DF), Hydrogen Chloride (HCl), and Deuterium Chloride (DCl). The practical difficulties associated with this type of lasers suggested that alternative route might be quite useful. Thus particular attention was paid to the development of computer program to investigate various energy characteristics. Comparison of the calculated results for different molecules shows that the highest values for the HF molecule probably due to their higher constants in comparison with the other molecules.

Blood samples of One hundred and twenty patients from different hospitals in Baghdad infected with hydatidosis in different sites of the body (Liver, Lung, multiorgans and kidney) were collected for this study. On the other hand, 30 healthy individuals were included as a control group.
This study was conducted to evaluate the effect of this disease on the serum protein profile of the patients using electrophoresis.
The results revealed four different protein banding patterns with difference in number
of bands and their molecular weights in comparison to the control group, and these differences depended on the site of infection. However the data showed a presence of the same band in all patients with different site of infection.
THIAMINE – INDUCED FORMATION OF THE MONOPYRROLE MOIETY OF PRODIGIOSIN
Authors: AL-Arrji Sanad B. , Ahmed Zeena F. , Kareem Anas G. Abdul
Published: March 2024

Thiamine stimulates the production of a red pigment , which is chromatographically and spectrophotometrically identical to prodigiosin , by growing cultures of serratia marcescens mutant 9-3-3 . this mutant is blocked in the formation of 2- methyl -3- amyl pyrorol( MAP),the monopyrrole moiety of prodigiosin , but accumulates 4-methoxy-2, 2-bipyrrole -5- carboxaldehyde (MBC) and can couple this compound with( MAP) to form prodigiosin .
Addition of thiamine caused production of( MAP) , and as little as 0.02 mg of thiamine / ml in peptone- glycerol medium stimulated production of measurable amounts of prodigiosin. Phosphate saltes and another type of peptone decreased the thiamine- induced formation of prodigiosin ,yeast extract and glycerol enhanced formation of this substance.
Thiamine also enhanced production of prodigiosin by wiled – type Strain Nima of S. marcescens .
The pyrimidine moiety of thiamine was also 10% as effective as the vitamin ; the thiazol moiety only 4% , and the two moieties together , 25% .
Thiamine did not stimulate production of prodigiosin biosynthesis as strain 9-3-3 .
This is not surprising since strain 9-3-3 originated as a result of two mutational events one event may involve thiamine directly , and the other may involve the biosynthesis of( MAP).

Published: March 2024

A rapid and sensitive method for analysis of amino acid hydrolysates of nigella sativa L seed has been developed using O-phthaldialehyde(OPA ) as a pre-column derivatizing agent. OPA reagents in the presence of mercaptoethanol react rapidly with primary amino acids ( less than 60 sec.) to form isindole derivatives which easily separated with good selectivity on ODS column.
Resolution of amino acid derivatives is carried out with a methanol gradient in 0.01 maqueous sodium acetate. pH 7.1 .
The quantitation of amino acid derivatives is reproducible within an average relative deviation of + 1.4% the linearity for most amino acids were more than 0.9993 with detection limit of 0.2 ppm. 15 amino acid were detected in the analysis of the seed protein hydrolysate. The presence of glutamic acid, alanine, leucine, cystine phenylalanine, aspartic acid in large quantities. The common separated amino acids were detected by U.V at 338 nm within 21 minutes.
