Authors: Lousada Arochena José Fernando
Published: March 2023

Comentario de una sentencia de la Sala de lo Social del Tribunal Supremo de España en la cual se reconoce el derecho a la suspensión del contrato de trabajo y prestación de adopción a favor de la esposa del padre biológico cuando aquella adopta al hijo de este nacido por gestación por sustitución y con el cual convivió desde el nacimiento. Aunque la sentencia resuelve la cuestión atendiendo a la normativa anterior al Real Decreto-ley 6/2019, de 1 de marzo, de medidas urgentes para garantía de la igualdad de trato y de oportunidades entre mujeres y hombres en el empleo y la ocupación, la doctrina que en ella se sienta es válida para resolver casos que se pueden plantear posteriormente.

Commentary on a judgment of the Social Chamber of the Supreme Court of Spain in which the right to suspension of the employment contract and social security provision for adoption is recognized in favor of the wife of the biological father when she adopts his son born by surrogate pregnancy and with whom she lived from birth. Although the ruling resolves the issue in accordance with the regulations prior to the Royal Decree-Law 6/2019, of March 1, on urgent measures to guarantee equal treatment and opportunities between women and men in employment and occupation, the doctrine that is established in it is valid to solve cases that can be raised later.
Ausencia de grabación del juicio oral y nulidad de actuaciones: el debate sobre la indefensión, en el centro.
Authors: Cavas Martínez Faustino
Published: March 2023

El Tribunal Supremo rechaza que la ausencia de grabación del juicio oral y del acta del Letrado de la Administración de Justicia en sustitución de la grabación audible sean causa automática de nulidad de todo lo actuado posteriormente, salvo que se alegue y pruebe por la parte recurrente la indefensión que tal circunstancia le hubiera ocasionado. A tal efecto, han de tenerse en cuenta tanto la actuación del órgano judicial como la naturaleza extraordinaria del recurso de suplicación y la limitación de los motivos por lo que dicho recurso puede interponerse.

The Supreme Court has ruled out that the absence of recording of the oral process and of the minutes of the Judicial Law Clerk in substitution of the audible recording are automatic cause for nullity of everything acted subsequently, unless it is alleged and proven by the appellant the defenselessness that such circumstance would have caused. To that end, account must be taken of both the action of the court and the extraordinary nature of the appeal and the limitation of the grounds on which such an action may be brought.
¿Discriminación laboral por parentesco? Sus límites (en especial, en pequeñas empresas)
Authors: Rojo Torrecilla Eduardo
Published: March 2023

La sentencia objeto de estudio trata sobre una problemática poco frecuente en el ámbito de las relaciones de trabajo, la discriminación por razón de parentesco; es decir, por la vinculación, de hecho o de derecho, con otro trabajador de la empresa. Frente a la alegación de haber sido discriminada la persona trabajadora despedida por dicho motivo, la sentencia procede al examen detallado del caso y concluye que no existe tal discriminación, tanto por no haber quedado acreditados los indicios de aquella, como por la normalidad real de tales relaciones familiares en empresas de pequeña dimensión, y tal era el caso de la empresa en la que se produjo el conflicto.

The judgment under study deals with a not very frequent problem in the field of employment relations, namely discrimination on the grounds of kinship, i.e. because of a de facto or de jure relationship with another worker in the company. Faced with the allegation that the dismissed worker had been discriminated against for this reason, the judgement proceeds to a detailed examination of the case and concludes that there is no such discrimination, both because the evidence of discrimination has not been accredited, and because of the real normality of such family relationships in small companies, which was the case of the company in which the conflict arose.

Authors: Chehlaeh Nareemas , Promfu Tatphicha , Masae Nusreen
Published: March 2023

The new results of light variability and frequency analysis of a high amplitude δ Scuti star (HADS) V593 Lyr were reported. δ Scuti-type variable stars are fascinating short-period stars with luminosity classes from III to V and spectral types from A0 to F6. Their location on the Hertzsprung-Russell (H-R) diagram is in the classical cepheid instability strip. The photometric data in the V filter and clear filter of V593 Lyr were collected from the American Association of Variable Stars Observers (AAVSO) international database. Discrete Fourier transformation and pre-whitening methods were used in the Period04 package to examine time-series light curve data. During 15 observational nights, we obtained 28 times of new light maxima magnitude variability and significant pulsation frequencies for the star. The study found that the fundamental frequency of V593 Lyr is 9.7894180 ± 0.0000002 d−1, corresponding to the main pulsation period of about 0.1021511 d and detected its second to fifth harmonics with a signal-to-noise ratio (S/N) of more than four. A study of the pulsation frequencies and period change of HADS stars can estimate their pulsation modes and evolution. Moreover, HADS stars are suitable targets for understanding asteroseismology, which is the subject that applies a star's pulsations to investigate its internal structure, and the high amplitude stars provide reference points for calculating cosmic distances in the Universe.

Authors: Kosinwattana Suriya , Anuwong Chamaiporn
Published: March 2023

Caladium is a tuberous plant propagated by the tuber section technique to increase the plant quantity. Gibberellin (GA3) and indole-3-butyric acid (IBA) have great capability in various agricultural practices, such as growing rapidly and enlargement tuber size. The effects of different tuber section sizes and PGRs levels having the following constituents (GA3 and IBA) in different levels by 2x5 factorial in a completely randomized design (CRD) with ten replications. The treatments involved 2 factors: The first factor was separating two sizes of tuber section into a squall length of each size 0.5 and 1 cm, and the second factor was drenching the tuber in two different levels of each IBA (100 and 150 ppm) and GA3 (100 and 150 ppm). The results obtained from this experiment showed that the 1 cm of tuber section size was a higher significant difference in bud germination, tuber size, plant height, canopy width, and the number of leaves than the 0.5 cm of tuber section size. However, IBA at 150 ppm was a higher significant difference in the average survival rate, bud germination, plant height, canopy width, and the number of leaves than others. The interaction between the tuber size at 1 cm and IBA at 150 ppm gave the highest survival rate, bud germination, plant height, canopy width, and the number of leaves. Therefore, the Caladium was separated at 1 cm size and immersed in 150 ppm of IBA appropriated to induce growth after the section within two months.
Applying the Flyweight Design Pattern to Android Application Development
Authors: Ngaogate Wasana
Published: March 2023

This research aims to demonstrate how the Flyweight design pattern enhances programmers' ability to develop mobile applications while being aware of memory consumption flexibly. By following the systematic approach to software development, the two Android applications have been designed using a class diagram based on two paradigms: general object-oriented programming and the Flyweight design pattern. Both applications are developed in Java and installed on a physical Android phone. Memory usage is monitored by using the Android Profiler and using programming. The results show that both Android applications consume almost the same amount of memory, given all classes or package classes. Therefore, applying the Flyweight design pattern to mobile software development does not affect memory usage and follows a professional software design.

Published: March 2023

The study aims to produce composite boards from two bamboo species i.e., Bambusa blumeana and Dendrocalamus asper. The composites were termed as “strip-board” and “shavings-board” to indicate that such was processed from shavings and strips, respectively. The strip-board was produced from 1.2 meter poles. The poles were turned into slats and were deskinned, denoded, and further processed into thin long strips. The shavings-board were made from the internodes converted into slats, deskinned, and processed into thin materials. During defibering, the vascular bundles were cooked in three varying NaOH-water concentrations (i.e., 1%, 3%, and 5%) for 3 hours. The cooked bundles were thoroughly washed and dried to 14% MC, applied with polyvinyl acetate, and pressed at 1000 psi. The produced boards were cured, dried, and samples were subsequently tested for tensile, compression, and bending strength following the ASTM D-143-22 standards. The data were analyzed using the 2×2×3 (i.e., species, board type, NaOH concentration) factorial experiment in CRD. Results showed that the pressing pressure used was insufficient to produce void-free boards. No interaction was noted between the three factors, but the main effect indicated that B. blumeana has significantly higher tensile and compression strength compared to D. asper. The strip-boards also obtained the same compared to shavings-boards. Despite the strength properties exhibited by B. blumeana, boards from D. asper were economical because of the lower price per pole and production cost. We conclude that the high pressing pressure was the most crucial factor in producing void-free, tightly compacted dense boards

Authors: Xia Zhengbing
Published: March 2023

Different proportions of waste concrete are mixed into the surrounding rock with crushing agent, and the boundary moisture content, the linear shrinkage rate, the expansion force test, the compaction test, the unlimited compressive strength and the CBR test were verified under different curing times. The surrounding rock stress state has significant spatial-temporal effects. Around the stress evolution process of the surrounding rock in the roadway excavation, the space-time effect of the surrounding rock stress distribution of the circular roadway under the uniform stress field is preliminarily analyzed, and the correlation of time and space and other related parameters is discussed. The study shows that the XiYuan model can fully reflect the stress relaxation effect of surrounding rock, and the three-way stress decreases with time and finally stabilizes in a certain balance state. In the early stage, the more obvious the stress concentration, the stress relaxation; the mechanical relaxation behavior of surrounding rock is a space-time function, the radial stress decreases with the rear distance of the excavation surface, and the annular stress is just opposite, while the axial stress remains unchanged. This study can provide a theoretical basis for the stability prediction and evaluation of rock mass roadway engineering.

Nowadays, the world is in a critical period of energy utilization transformation, and the development of the automobile industry is greatly influenced by energy. New energy vehicles represented by electric vehicles are the new direction of the development of the automobile industry in the future. The AVL-Cruise software system has many features, such as simple modeling function, visual design analysis and research, which provides technical support for the simulation projects under complex working conditions of vehicles. Taking the front wheel drive pure electric vehicle as an example, this paper uses AVL_CRUISE software to establish the power system model of electric vehicle, and uses this software to calculate its dynamic performance. The simulation results show that the maximum speed is 178km/h, the 100km acceleration time is 11.59s, and the maximum climbing slope is 30%. The simulation results show that the electric vehicle meets good design requirements. The total energy consumption is 4608KJ. By changing the data such as air resistance coefficient and vehicle quality, the relationship between the dynamic performance and the influencing factors is explored. The corresponding expression is obtained by fitting the data, which provides data support and reference experience for the optimization of electric vehicles.

The identity of dark matter and dark energy which makes up 85-90% of the total mass in the universe, is one of the biggest unresolved issues in particle physics according to BBC Science Focus Magazine. So what do dark matter and dark energy do? They play an important role in galaxy formation and the universe's expansion. It is one of the most accepted theories that support the universe's expansion that gravity pulls galaxies together, while dark energy pushes them apart. Which force is stronger? Gravity or dark energy determines whether the cosmos is expanding or contracting. [1]. As an illustration, the Big Bang diagram down below shows that the universe’s expansion speed is increasing and eventually getting progressively faster and is affected by dark energy.

The Relationship between Enterprise Equity Incentive and Earnings Management in Big Data Era
Authors: Wang Sixuan
Published: March 2023

With the development of China's securities market, earnings management of listed companies has attracted more and more attention from creditors, shareholders, securities regulatory authorities and other stakeholders. Equity incentive has two sides. If it can be effectively used, it will greatly mobilize the enthusiasm of management and bring about long-term incentive effect. Unlike mature western markets, China's securities market is an emerging market in a transitional economy. Because there is not a high correlation between the degree of earnings management and the compensation level of the management in China's listed companies, the motivation of the management to improve their compensation level is not significant for the purpose of self-interest. This paper analyzes the relationship between equity incentive and earnings management of Listed Companies in the era of big data, focusing on the relationship between equity incentive and earnings management.

Authors: Adamek-Hyska Dorota , Franczak Iwona
Published: March 2023

Purpose: The budget reporting system plays an important role in reporting the achievements of local government units regarding how these entities communicate with the environment and various stakeholder groups. The main purpose of the study is to assess the usefulness of reporting information on budget expenditures by selected local government units. The authors were interested in the importance of budget expendi-ture commitments, their functions, and whether the commitment of budget expendi-tures should be presented in the reporting system of local government units.Methodology/approach: The article contains a review of the literature on the subject and legal acts. In the empirical part, the study covers annual budget reports RB-28S from the implementation of the financial plan of budgetary expenditures for the years 20192021 of local government units. r-Pearsons linear correlation analysis was used. Findings: Statistical inference confirmed the low relevance of the expenditure commitment category in budget reporting. A very strong positive correlation with realized expenditures shows that showing the involvement of expenditures next to the incurred expenditures only doubles the value of expenditures. Research limitations/implications: The article may be an inspiration for further research, including comparative research, on the same units or extended to other local government units. Originality/value: The authors draw attention to the lack of research on the usefulness of financial data presented in the budget reporting system.

Published: March 2023

A set of 24 FAO recommended microsatellite markers was evaluated for parentage exclusion (PE) in three Indian pig types of Assamese, North-Indian and Ankamali. The genomic DNA from these three Indian pig types was amplified at these loci by polymerase chain reaction and resolved for alleles. The allelic frequency data was analysed to calculate the probability of paternity exclusion when one of the parents is to be excluded (PE1), when both the parents are to be excluded (PE2) and when only one parent is known and that is to be excluded (PE3) in these three Indian pig types using a set of minimum 5 loci and then increasing the number of loci in increments of 5 upto maximum of 24 loci. The cumulative PE1 values taking into consideration all the 24 loci varied from 1-2.07×10-10 in North Indian pigs to 1-3.95×10-11 in Ankamali pigs. The cumulative PE2 values taking into consideration all the 24 loci varied from 1-4.57×10-16 in Assamese pigs to 1-3.17×10-18 in Ankamali pigs. Similarly, cumulative PE3 values for all the 24 loci varied from 0.9999968 in Assamese pigs to 0.99999955 in Ankamali pigs. The cumulative PE values obtained, even with a set of 15 loci (CGA, IGF1, S0005, S0026, S0068, S0090, S0155, S0178, S0215, S0218, S0228, S0355, SW122, SW911, SW936), were clearly more than the required value of 0.9995 in all the three breeds with the minimum value of 0.99985 for PE3 in Assamese pigs. Clearly, this set of 15 loci or the sets with 20 or 24 loci can be safely employed for parentage exclusion purposes in the Indian pigs.

The study investigated the effects of zinc oxide nanoparticles on some of the antioxidant biomarkers and enzyme serum in broiler chickens during starter stage (1-21d). A total of 240 one-d-old broilers (Ross-308) were randomly divided into four groups, with 60 birds in each group and 4 replicates with 15 birds in each experimental pen. The experimental diets were T1, Control (basal corn-soybean diet supplemented with 36.27 mg Zn/kg from zinc oxide; T2, T3 and T4, basal corn-soybean diets supplemented with 30, 60 and 90 mg ZnO-NPs/kg, respectively. Dietary ZnO-NPs supplementation significantly increased total antioxidant capacity (TAC), super oxide dismutase (SOD) and glutathione peroxidase (GSH-Px) enzyme activity in test groups compared to the control. However, the serum enzyme activity of lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase in the birds fed ZnO-NPs had not significantly altered in comparison to control group. However, a decreasing trend was observed in the activity of ALT and AST enzymes in the birds fed 60 and/or 90 mg ZnONPs. Also, the MDA concentration was numerically decreased compared to the control group. In conclusion, results of study suggest that dietary zinc oxide nanoparticles @ 90 mg per kg of basal diet improved antioxidative status and activity of some enzymes used as body health indicator in the broilers during starter period (1-21 d).

Field investigations were also carried out on other milking management practices, IMI, hygiene status and cleanliness in 3 stages. A total of 459 milk samples were analysed. Farm experimentation revealed that SCC and MCMT were significantly higher in hand milking as compared to machine milking management. But milk yield and milk extraction rate were significantly lower in hand milking as compared to machine milkingmanagement. The time required for milking/animal was significantly higher in hand milking as compared to machine milking management. The morning and evening milk samples of both hand and machine milking showed higher values of SCC, MCMT, pH during evening as compared to morning session but milk yield and milk extraction rate were lower during evening as compared to morning session whereas time required for milking/animal was higher in morning as compared to evening time. Almost similar trend of fat and SNF (%) were estimated in both milking session. Field investigation indicated that SCC, MCMT, pH were higher in IMI animal as compared to no-IMI animal whereas fat and SNF were lower in IMI animal as compared to no IMI animal. Teat dipping and screening of udders for mastitis were never followed by any farmer. Most of farmer having single cow, maintained good hygiene status and cleanliness but most of the farmer having >3 cows, maintained poor hygiene status. Farm experimentation concluded that the IMI can be reduced in machine milking practices in comparison to hand milking practices with higher milk quantity without affecting milk composition in Jersey crossbred cows. Field investigation concluded that there is a significant association between animal keeping pattern and hygiene status/cleanliness at study area. So efforts should be made to increase cleanliness and hygiene status in milking cows itself, housing of animal and milkers of farmerâ€™s house to reduce incidence of IMI in changing scenario.

The results from the present study revealed that average age at sexual maturity was significantly higher in Ghungroo and Ghungroo × Hampshire female pigs than nondescript local pigs. The average age at first farrowing was significantly higher in Ghungroo and Ghungroo × Hampshire pigs than nondescript local pigs. The litter size at birth was significantly higher in Ghungroo than nondescript local pigs but not significantly different from Ghungroo × Hampshire. The litter size at weaning was 8.6±0.27, 8.4±0.27 and 4.6±0.31 in Ghungroo × Hampshire pigs, Ghungroo and nondescript local pigs, respectively. The litter weight at birth and at weaning was recorded highest for Ghungroo × Hampshire followed by Ghungroo and nondescript local pigs. There was significant difference in body weight at 6 and 9 months of age in Ghungroo, Ghungroo × Hampshire and nondescript local. Farrowing interval was significantly higher in nondescript local pigs than Ghungroo and Ghungroo × Hampshire. The findings of the present study indicated that Ghungroo and Ghungroo- Hampshire crossbred pigs can perform better in terms of production potential and adaptability even on existing low input rearing systems in climatic condition of Garo hills of Meghalaya.

Turf grasses are the plants which form a continuous ground cover and is the assurance of a lush, high-quality lawn but the presence of weeds during green establishment can reduce growth and turf quality. Field experiment was conducted to investigate efficacy of Pendimethalin (1.0 kg a.i./ha) â€“ pre emergence, Atrazine (1.0 kg a.i./ha) - pre emergence, Carfentrazone (30 g/ha)- post emergence (40 DAS), Metribuzin (300 g/ha) - pre emergence, Pendimethalin (0.75 kg/ha) + Metribuzin- pre emergence, Pendimethalin (Pre emergence) + Carfentrazone- (Post emergence), Pendimethalin (Pre emergence) + Metribuzin (Post emergence), Atrazine (Pre emergence) + Carfentrazone (Post emergence), Atrazine (Pre emergence) + Metribuzin (Post emergence), manual weeding (four hand weeding) on the establishment of Tif dwarf 419 Bermuda grass from sprigs. The results suggest that application of Pendimethalin @ 0.75 l/ha (pre-emergence) + Carfentrazone @ 0.0225 kg/ha (post-mergence) at 40 days after sowing was effective for controlling the weeds followed by Atrazine @ 0.75 l/ha (pre-emergence) + Carfentrazone @ 0.0225 kg/ha (postemergence) at 40 days after sowing. Carfentrazone (30g/ha) alone as post emergence herbicide recorded about 75% weed mortality.

Present study was conducted to determine the genetic diversity at molecular level among 21 thermo-tolerant tomato accessions. All the accessions were screened by using 18 simple sequence repeats (SSR) primers to estimate genetic diversity and genetic relationships among these accessions. Among the 18 SSRs, only 5 primers (SSR47, TES628, TGS149, TGS230 and TGS330) were polymorphic which were used for accessing the genetic distance to find out the phylogenetic relationship among the different tomato accessions. Polymorphism information content (PIC) ranged from 0.17 (TGS230) to 0.36 (TGS149) with average PIC as 0.30. Unweighted pair group method with arithmetic mean (UPGMA) clustering grouped the accessions into two main clusters. The information related to genetic diversity presented in this study might be useful to breeders for planning crosses among these accessions for future tomato breeding programmes.

Pleurotus spp. are the most commonly cultivated and consumed mushrooms in India. This mushroom grows on almost all kinds of traditional as well as the non-traditional biomass sources giving good yield. In the present study, Panicum virgatum and Panicum maximum grasses were utilized for the cultivation of Pleurotus florida. The highest biological efficiency was obtained in case of 50% WS + 50% PM (68.45%) followed by the 100% WS (66.43%). The harvested fruiting bodies analysed for the nutritional parameters revealed that significant difference was found among the fruiting bodies produced on the selected agrowastes studied for the different proximates analyzed especially in protein content. Based on the biological efficiency of the substrates tested, utilization of Panicum maximum biomass seems to be a promising supplement with wheat straw for growing P. florida.

China aster [Callistephus chinensis (L.) Nees] is commercially grown as annual flower crop for cut flower and loose flower. It is used for flower decoration, preparation of bouquets and garlands. It belongs to the family Asteraceae and is native of China. Morphological characterization of China aster genotypes was carried out in the division of Floriculture and Medicinal Crops, ICAR-IIHR, Bengaluru during 2015-16 and 2016-17 by adopting DUS guidelines developed by Protection of Plant Varieties and Farmers Rights Authority, New Delhi. A total of 42 genotypes were characterized for 21 traits belonging to vegetative and floral traits. Among these 21 traits, two were monomorphic, four dimorphic and 15 were polymorphic indicating their potential for varietal characterization. This characterization clearly established distinctness among the different genotypes for various traits. This study will be useful for breeders/farmers to identify and differentiate China aster genotypes and to pursue protection under PPV and FR Authority, New Delhi. The characterizations of genotypes will also results trait specific information which can be used in the development of superior genotypes in China aster.

Pea (Pisum sativum L.) is moderately tolerant to salinity, early vegetative stage being more sensitive to salinity. In view of this, twenty pea genotypes collected from IIVR, Varanasi were screened for salt tolerance in terms of physiological and biochemical traits. The experiment was conducted in randomized complete block design in pots filled with soil (EC 20.47 dS/m) in 3 replications. Osmotic stress was created with irrigation water of salinity ECiw6 and 9 dS m-1 alongwith best available water (BAW) having ECiw 0.6 dS m-1 (control). It was found that mean photosynthetic rate (Pn)decreased with increasing levels of salinity in all the genotypes except VRPMR-11 (12.6%), VRP-5 (16.18%) and VRP-22 (16.5%) at ECiw9 dSm-1.The chlorophyll content was also significantly higher in VRPE-25, VRP-5 and VRPE-100 over all the treatments. Fv/Fm values reduced by 12.9% at ECiw6 dSm-1 and 24.19% at ECiw9 dSm-1. The best indicator of stress, proline accumulated many folds with increasing levels of salinity, i.e. approximately 8 folds proline content at ECiw6 dSm-1 and 13 folds proline content at ECiw9 dSm-1 was observed. The membrane damage in terms of lipid peroxidation was measured as MDA content and accumulated significantly at higher saline level followed by ECiw 6 dSm-1 and least in control. Leaf K+/Na+ ratio decreased significantly with increasing stress level. Among the genotypes, significantly higher K+/Na+ was observed in VRP-22, whereas minimum in VRP-343 and VRPE-25. More than 80 % reduction in yield was observed in pea genotypes VRP-6, VRPE-100, BB-29(b)-14 green, VRP-233, PC-531, VRP-12-1 and VRP-7, whereas the minimum reduction was obtained in VRPE-101 (39.1%), VRP-343 (43.2%), Pusa Pragati (43.8%), VRP-22 (45.8%), and VRPE-25 (48.37%) at ECiw9 dS m-1. Thus on the basis of the physiological and biochemical expressions of tolerance, these genotypes were characterized as sensitive, moderately tolerant or tolerant to salinity.
