Published: November 2022

Kualitas spermatozoa ayam bangkok dipengaruhi oleh kualitas pakan. Pada penelitian ini dievaluasi pengaruh pemberian pakan yang mengandung tepung kulit ari biji kedelai fermentasi (TKABKF) terhadap kualitas semen dan spermatozoa ayam bangkok. Materi yang digunakan adalah 4 ekor ayam bangkok berbobot 3,3kg sebagai sumber semen dan spermatozoa yang dievaluasi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Perlakuan formula pakan terdiri atas: pakan komersial BP-11 sebagai kontrol (P0), BP-11+5% TKABKF (P1), BP-11+10% TKABKF (P2), dan BP-11+15% TKABKF (P3). Variabel yang dievaluasi meliputi karakteristik semen (volume, warna, bau, konsistensi, dan pH semen) dan spermatozoa (konsentrasi, pergerakan massa dan motilitas spermatozoa). Hasil penelitian menunjukkan bahwa rata-rata volume semen adalah 0,41ml/ejakulasi; warna putih susu, konsistensi kental, bau khas dan nilai pH 6.34. Sedangkan rata-rata konsentrasi spermatozoa adalah 1,51 miliar/ml; gerakan massa 2,50 dan rata-rata motilitas spermatozoa 86,00%. Selanjutnya hasil analisis varians menunjukkan bahwa penambahan TKABKF ke dalam pakan berpengaruh nyata terhadap volume semen ayam bangkok tetapi tidak berpengaruh terhadap variabel lainnya. Volume semen tertinggi diperoleh pada perlakuan P3 (15% TKABKF) yang secara nyata lebih tinggi dibandingkan volume semen ayam pada perlakuan kontrol. Akhirnya dapat disimpulkan bahwa penambahan TKABKF ke dalam ransum hingga 15% dapat meningkatkan volume semen ayam bangkok.

Incorporation of Rice Residues Through Tillage Enhances Soil Organic Matter Accumulation in Rice Land
Authors: Fiegalan Fernan , Ringor Cherry , Moya Tolentino
Published: November 2022

Soil organic matter (SOM) is a critical determinant of the fertility status and productivity of soil, yet SOM status in rice land is degrading. This study was conducted through integrated in situ experimentation (collembola, bacteria, fungi, moisture, temperature, N, P, K) and modeling to determine how to enhance SOM in rice land. An approach to increase SOM by incorporation of rice residues (straw and stubble) through tillage was done. While previous SOM assessment only looked into fine particles (< 0.05 mm, Fn), this study includes both fine and coarse (0.05–2 mm, Lf) SOM fractions. Incorporation of rice residues by tillage increased Lf by 27% (P < 0.001 at 0.05α) while it decreased Fn by 7% (P = .006 at 0.05α). Long-term projection of SOM status generated using system dynamics (SD) modeling showed higher accruals of Lf in the tilled soil due to the physical fragmentation of rice residues. The accumulation of Fn in non-tilled soil was attributed to the synergistic effect of collembola, bacteria, and fungi on the further decomposition of available Lf. Incorporation of 15 T ha–1 yr–1 of rice residues showed accrual of SOM at a rate of 0.03% yr–1. SOM state was observed to decline at –0.003% yr–1 when rice residue incorporation was reduced to 10 T ha–1 yr–1 with a rate of –0.003% yr–1, and –0.04% yr–1 when the residues were further cut down to 5 T ha–1 yr–1. Continuous practice of rice residue incorporation at 20 T ha–1 yr–1 showed tenable SOM accrual and projected to contain > 4.0% within 25 yr. Contrary to previous work, this study showed that incorporating rice residues through tillage enhanced the Lf fraction and, consequently, increased the total SOM.

Published: November 2022

The RAD51 gene encodes the protein that plays a central role in the repair of DNA double-strand breaks (DSBs) through the homologous recombination pathway. Association of RAD51 single nucleotide genetic polymorphism (SNP) with the development of cancer has been observed to be tumor site- and race-specific. Thus, this study aimed to determine the potential association between RAD51 135G>C SNP and breast cancer among selected Filipinos. Patients with histologically confirmed breast cancer (n = 60) seen at the University of Santo Tomas Hospital (USTH Manila) were age- and sex-matched with clinically healthy controls (n = 60). Genomic DNA was extracted from the blood of participants and analyzed for RAD51 genotype by polymerase chain reaction – restriction enzyme fragment length polymorphism (PCR-RFLP). A significantly higher incidence of RAD51 C/C genotype was seen among the cases than the controls (p < 0.05). The more common G/C genotype was not associated with breast cancer development, while the recessive less common C/C genotype was observed to potentially increase the risk. However, passive smokers carrying the RAD51 G/C genotype had a significantly increased chance of developing breast cancer. RAD51 G/C genotype – even when combined with other established risk factors like alcohol use, active smoking, and family history – were not associated with breast cancer.
Digital Image Photometric Analysis of Nickel(II) in Alkaline Solution with Dithizone as Complexing Agent Using a Mobile Phone Camera
Authors: Pagala Angelica , Ravidas Cherry Mae , Pillas Jennifer , del Rosario Ernesto
Published: November 2022

Quantitative analysis of nickel(II) in aqueous alkaline solution, with dithizone as a complexing agent, was done using digital image photometry (DIP) and the results were compared with those using conventional visible spectrophotometry (VS). Digital color photographs of prepared standard and sample solutions of Ni(II) were taken using a fabricated lightbox with a 24-well sample holder and iPhone 5S mobile phone camera. RGB values were determined from the photographs using ImageJ software and plots of Red value, L*, a*, and b* as DIP parameters were constructed in order to calculate Ni(II) concentrations. No significant differences in Ni(II) concentrations were observed at a 95% confidence level based on DIP and VS. Performance criteria were set and various tests were conducted for the limit of detection (LOD), limit of quantification (LOQ), linearity/working range, repeatability, and selectivity. The DIP results satisfied the minimal requirements in terms of method validation criteria according to published guidelines. Among the DIP parameters, b* gave results with the highest linearity and accuracy based on the coefficient of determination (R2), as well as plots of least significant differences (LSDs) and linear regression residuals. The results of the present study show that DIP, which uses a relatively inexpensive mobile phone camera, is a promising alternative to the conventional method using an expensive spectrophotometer.
Electrochemical Reversible Copper Oxide (CuO) System on Multiwalled Carbon Nanotube Paste Electrode (CPE) as Sensor for Hydrogen Peroxide in Wound Cleaning Solution
Authors: Buenaventura Angelo Gabriel , Yago Allan Christopher
Published: November 2022

An electrochemical sensor for hydrogen peroxide (H2O2) was prepared and optimized in this study. The sensor recognition element consisted of mainly copper oxide (CuO) particles electrodeposited on an anodized multiwalled carbon nanotube paste electrode (MWCPE), which is composed of multiwalled carbon nanotubes (MWCNT) and polydimethylsiloxane (PDMS). Chronoamperometry (CA) was used as the electrodeposition technique both for Cu deposition and oxidation to CuO. The layer of CuO was shown to react with H2O2, which lead to measurable voltammetric current at varying concentrations of H2O2. Different parameters were optimized as follows: Cu deposition time, Cu oxidation time, and equilibration time. Differential pulse voltammetry (DPV) was used as the main sensing technique for CuO-CPE. DPV measurements showed that the average peak current (ave. Ip) was found to be increasing linearly with increasing H2O2 concentration. Two H2O2 concentration ranges, low concentration (20 μM – 100 μM) and high concentration (400 μM – 1200 μM), were observed to have a linear correlation with ave. Ip. The limits of detection (LODs) were calculated to be equal to 11.40 µM using the low concentration range, while 13.04 μM using the high concentration range. The H2O2 measurements using CuO-CPE were found to be reproducible and repeatable. Real sample analysis was also performed on a wound cleaning solution (aqua oxigenada, 6% H2O2 w/w) as a sample. From the measurements, the H2O2 concentration of the analyte was found to be 6.16% w/w; the calculated % error was equal to 2.67%. Overall, CuO-CPE composite was shown to be an effective electrochemical sensor for H2O2 analysis.
Cross-infectivity of a Putative Spodoptera picta Nucleopolyhedrovirus to Spodoptera litura Fabricius (Lepidoptera: Noctuidae)
Authors: Javier-Hila Abigaile Mia , Caoili Barbara
Published: November 2022

A putative nucleopolyhedrovirus (NPV) from a field-collected local Spodoptera picta population was isolated for the first time. Its pathogenesis was described in S. picta larvae and was tentatively assigned the name Spodoptera picta nucleopolyhedrovirus or SppiNPV. With the objective of utilizing this SppiNPV as a biological control agent, its cross-infectivity to S. litura – a very important agricultural pest in the country – was evaluated. Third instar S. litura larvae were infected with approximately 100 occlusion bodies (OBs) of SppiNPV using artificial diet- incorporation. SppiNPV infection in S. litura was clearly observed as the 4th instar larvae exhibited pinkish coloration, a characteristic sign of NPV-infection. In addition, the integument of the mildly-infected larvae easily twisted when touched and often expelled slimy fluid from their mouth. At the advanced stage of infection, larvae became extremely fragile resulting in cuticles that were easily ruptured. At 6 d post-infection (dpi), 20% mortality was observed in the SppiNPV-treated S. litura. At 16 dpi, all the cutworms in the control set-up emerged as normal adults, while only three cutworms (10%) in the NPV-treated larvae emerged as adults but with short malformed wings and abnormally soft and fragile abdomen. The effect of SppiNPV on the weight gain of S. litura larvae was also monitored at 4 and 6 dpi. Although significantly higher weight (F = 5.09; df = 58; P > 0.0278) was recorded in the untreated cutworms than the NPV-treated cutworms at 4 dpi, weight gain did not significantly differ in SppiNPV-infected and untreated larvae. Overall, a significantly higher mortality of 46.67% (F = 25.37; df = 58; P > 0.0001) was recorded in SppiNPV-infected cutworm larvae. Further studies to characterize this novel SppiNPV, increase its virulence to S. litura through the continuous passage in S. litura, and optimize the amount of OB to be applied to ensure 100% mortality are recommended so that it can be used as a biological control agent with expanded host range.

Published: November 2022

In this paper there are presented the influence of the various parameters which could be involved in the collapse of the roof concrete structures of the Cluj Sports Hall in February 15th 1961 soon after the total solar eclipse. This study takes into consideration the multiple causes for the collapse include the thermal shock due to the solar eclipse, the inappropriate projection of the roof and the cracks in the structure after winter and exactly the rain conditions in previous night of the collapse. This parameters where involved in modeling the structure with SCIA Engineer v16.0. The conclusions of this study reveals as a major factor for collapse the rising the weight of the roof structure due to water accumulation in the cracks of the roof and the secondary cause the superposition of the specific thermal field due to the total solar eclipse. Using the Energonics principles, the superposition of the two main loads (mechanical and thermal), there were performed a lot of iterations in ETABS analysis to determine the load which is responsible for collapse. In these days, the standards for roofs with these dimensions of openings are completely changed. The significance of this study is bonded with superposition of the natural effects above the structures and the partition of their influence. Also this study can be used as a critical analysis of the type of projecting the roof structures in 1960s. This paper presents also a hypothetical analysis with accumulation of snow beside of the other factors involved.

Published: November 2022

In this paper, we introduce a mathematical relation which allows prediction of frequency changes of beams if a damage producing an abrupt stiffness decrease occurs in the structure. This relation is contrived from the energies stored in the beam in the intact, respectively in the damaged state. First, the analysis was performed for the damage reducing the stiffness of the slice subjected to the biggest bending moment. From this analysis, we found the damage severity evolution, reflected in a frequency drop, with the damage depth. Afterward, we replaced this damage on several locations along the beam and quantified the effect upon the natural frequencies for each of them. Based on this analysis, we found out also the effect of damage position upon the natural frequencies. The final relation resulted by aggregating the effect of the severity with that of the position. To prove the reliability of this relation, we tested it against results obtained by means of the finite element method.

Published: November 2022

In this paper we present a software module for object recognition before robotic gripping with an anthropomorphic gripper. To this effect, recognizing the shape of an object using digital image processing algorithms, falling in the area of digital sequences processing, is important. This area has evolved a lot lately, in particular due to the progress of computing resources, involving parallel processing of each basic unit of an image. The paper summarizes the theoretical background and the results related to the software developed for this purpose, called SpatialVISION. To implement the SpatialVISION application, the implementation of the SIFT algorithm was used, which is a personal approach in C #, using EmguCV library for working with images. To use the SpatialVISION application, a tool called SVAdminUtility was also created, which is used to populate a database with three-dimensional objects that will later be recognized. In structural terms, the SVAdminUtility application has four functional components namely: SVAdminUtility component; Collada component; Viewer component and XSD2NET component. To assess the SpatialVISION application, an experiment was conducted, whose results are presented in the paper, which consists in measuring the average time of execution of the object recognition algorithm using two types of images captured by two types of cameras: a WEB camera and a Canon PowerShot camera.

Published: November 2022

Electroporation is the permeabilization of the cell membrane with brief, high electric fields. It is a technology of importance in bioengineering and medicine. An experimental study was performed to determine the effect of temperature on the electroporation parameters in individual cells. For this purpose, we designed a microelectromechanical device that maintains a controlled temperature and detects the threshold of electroporation by incorporating an individual cell into an electronic circuit. A series of experiments were performed with Madin-Darby Canine Kidney (MDCK) cells. We have found that the electrical field corresponding to the onset of electroporation, known as the critical electric field (EC), is a strong function of temperature. It increases with decreasing temperature. The critical electric field for electroporation at 5o C is as much as two times that needed to electroporate the cells at 37o C.

Published: November 2022

To begin the work presents some redundancy resolution schemes for robotic arms, i.e., the techniques for exploiting the redundant degrees of freedom in the solution of the inverse kinematics problem. This is obviously an issue of major relevance for motion planning and control purposes. In particular, task-oriented kinematics and the basic methods for its inversion at the velocity (first-order differential) level are first recalled. This paper focuses on modeling and simulations of the inverse kinematics of an anthropomorphic redundant robotic structure with seven degrees of freedom and a workspace similar to human arm. Also the kinematic model of the robotic arm in the MATLAB and Simulink environment is presented. A method of resolving the redundancy of a seven degrees of freedom robotic arm when a degree of freedom has a known variation is presented. The kinematic analysis and virtual simulation share similar results.

The aim of this paper is to determine the gradient and thermal stresses depending on the heating rates, based on parameters resulted from industrial studies, for the purpose of optimizing the heating of type 18-10 stainless steel ingots, considering the cases where the heating is required starting from the cold state. If the heating for the plastic deformation processing is to begin from the cold state, the determination of the heating rate up to the temperature of 700 – 800 ºC must be done with extreme care, as this is in fact the most conducive period to the formation of defects. Having analysed the existing domestic and foreign situation, the heating process for this type of steel raises difficult issues and differs from one company to another, relying mostly on their own accumulated experience. Despite the fact that, practically, the possibility of increasing the heating rate has been demonstrated, it is restrained by the fear of achieving an insufficient section heating and of the destruction of steel's tightness during the initial heating period. For these reasons we have taken the step of the analytical review of the gradient variation, as well as of the thermal stresses during the preheating period.

The interest for the topic dealt with was raised by the occurrence of the destructive Vrancea earthquake of 1977.03.04, when the first strong motion record of Romania was obtained at the Building Research Institute (INCERC) Bucharest. The attempt to assess the ground motion intensity on the basis of instrumental criteria of the MSK intensity scale failed, due to strongly divergent results obtained by means of alternatively using the peak ground acceleration (PGA) and peak ground velocity (PGV) criteria. This failure was due to the fact that the (inflexible) MSK criteria relied on the implicit, non-realistic, assumption that all ground motions are characterized by a velocity / acceleration corner period of 0.5 s. A flexible Spectral Intensity Assessment System (SIAS, relying on accelerographic information, was developed by the author. This makes it possible to estimate, according to needs, global intensity, frequency related intensity, intensity averaged upon a spectral band etc. Alternative basic kinematic ground motion characteristics for global intensities and for frequency related intensities were introduced. Correlation analysis was performed. Characteristic parameters were calibrated and alternative calibrations of them are discussed. Some illustrative cases and some comments and recommendations are finally presented.

The paper reviews the main indicators for the calculation of the optimal consumption of ventilation air for the metro in case of necessity dilution of different harmful substances. The above-mentioned harmful effects are mainly caused by: the number of passengers; harmful and toxic gases released from the mountain massif, as well as the exchange of heat and moisture between the massif and the air. Ventilation thermal calculation is one of the central issues to determine the air flow with sufficient accuracy and to establish rate of air exchange in underground space. The paper describes calculation of the natural temperature of the mining area for both stationary and non-stationary fields. The work also gives the thermophysical and mass-physical characteristics of the main rocks. The characterization of these coefficients is also shown in the fields of temperature and mass transfer potential.

In this paper we present a synthesis on the epistemological process of the discovery, invention and construction of Quantum Biological Thermodynamics with Finite Speed of the Cardio –Pulmonary System (QBTFSCPS) starting from Thermodynamics with Finite Speed Applied to Thermal Machines (TFS). We present first when and how Thermodynamics with Finite Speed of Thermal Machines was invented, developed and validated, and after that we show how we extended it to a Biological – Electrochemical - Thermal Machine, namely to the Cardio-Pulmonary System, creating what we call: Quantum Biological Thermodynamics with Finite Speed of the Cardio –Pulmonary System (QBTFSCPS).

Based on a new physical-geometrical model for a possible evolution of early universe, the resulting thermodynamic aspects and consequences are studied. By considering an initial singularity, similar to BIG BANG, containing the total energy of the universe, the apparition of this energy from chaos is justified by using the uncertainty relation of Heisenberg. In this way, the violation of the energy conservation law - therefore of the first law of Thermodynamics - is justified. Then, by applying the second and the third laws, one shows that Big Bang (more correct name would be Big Flash) is entropy increasing as any natural process. The emerging energy expands as a spherical wave at the speed of light generating space and time. A structuring model of the primary wave is adopted by reason of geometrical simplicity and satisfying the conservation laws. From thermodynamic point of view, an adiabatic transformation leads to an exponent close to the evolution of a mono-atomic gas. The entropy variation confirms by comparison the ordering character of universe structuring

It starts from a planetary mechanism that generates hypocycloids and it is completed with an RPP dyad, so that transfer functions are generated, i.e. races along the x and y directions. Different hypocycloids (normal, elongated, shortened) are generated and transfer functions are established for these cases. The obtained curves and transfer functions are discussed, establishing some conclusions. All study includes various range of lengths for the cinematic links so the important and interesting trajectories are found. The related transfer functions can be used in a diversity of applications. These findings are useful for special devices for automatic lathes, horizontal forging machines, textile machinery, and kinetic art.

. Environmental challenges imposed by greenhouse gases are currently well recognized and a worldwide commitment tends to be reached, to replace fossil fuels (mainly responsible for global warming and climatic changes) with renewables. Concepts were formulated, as the Net Zero Energy Building (NZEB), although the current building stock mainly consists of old buildings (97%). Thus, technical and cost-related barriers are faced and transition concepts are formulated, as the Nearly Zero Energy Building (nZEB), legally binding for the EU states (starting with 2019/2021), that may ease the transition and can be realistically met, considering the current situation. Following this pattern the paper proposes the Nearly Zero Energy Communities (nZEC) concept, as a transition path to be implemented in various geographical locations, with specific prerequisites. Different scenarios are discussed based on coherent technical solutions, involving large(r) community/districts; the public support is required for a clear definition of the short and long-term community gains.

Desde hace más de 30 años existen experiencias de quimioterapia domiciliaria que demostraron mejorar la calidad de vida y disminuir costos. Los objetivos del trabajo fueron evaluar la seguridad de los tratamientos quimioterápicos domiciliarios y la satisfacción del paciente. Estudio exploratorio entre febrero y agosto de 2018. Se evaluaron eventos adversos y tolerancia. Los protocolos de atención domiciliaria contemplaban la seguridad del paciente y del operador. Variables: edad, sexo, diagnóstico, efectos adversos, tolerancia al tratamiento, satisfacción del paciente. El análisis estadístico fue con medidas de resumen. Se incluyeron 26 pacientes, edad promedio de 64.69 años, 53.8% sexo masculino (n=14). Se realizaron 182 sesiones. El diagnóstico más frecuente fue cáncer de colon (n=3). Los protocolos más frecuentes fueron irinotecan y etopósido más cisplatino y bleomicina. La vía de administración más utilizada fue la endovenosa (n=135). Tolerancia: muy buena en 172 sesiones (95%), buena en el 5% (n=9) y regular en una. Se observaron eventos adversos inmediatos menores en tres sesiones (1.6%, n=2). En las 24 horas posteriores al tratamiento se informaron catorce eventos adversos menores (7.69%) en seis pacientes. No se observaron eventos mayores. En el 100% de las sesiones los pacientes refirieron sentirse igual de seguros que en el hospital de día y que continuarían su tratamiento en domicilio si tuvieran la opción. Nuestros resultados demuestran que basándose en criterios de selección y procedimientos adecuados se pueden administrar tratamientos oncológicos en domicilio con seguridad para el paciente y el operador, generando mayor comodidad.

La presencia de neoplasias múltiples es poco frecuente en la práctica clínica. Es posible que el aumento de la supervivencia global y las herramientas diagnósticas más eficientes, transformen este hecho en algo no tan inusual, siendo por tanto necesario contar con datos epidemiológicos para ampliar la información disponible.

El objetivo del trabajo fue conocer la frecuencia de segundas neoplasias durante un período de 5 años.

Se trata de un estudio observacional de corte transversal, retrospectivo y descriptivo.

Se excluyeron los pacientes con abandono del seguimiento.

Se revisaron las historias clínicas de 1219 pacientes durante un período de 5 años, enero de 2013 a diciembre de 2017.

Se detectaron 20 pacientes con dos tumores primarios (frecuencia 1.6%). El 85% está actualmente en control. La edad media al primer diagnóstico fue de 53 años. Sexo (%): M/F 8/12. El 15% se diagnosticó de forma sincrónica. El 35% tenía un familiar de primer grado con diagnóstico de cáncer. Dos asociaciones: mama-ovario, colon- recto tuvieron una frecuencia del 10%.

Es escasa la información actual sobre neoplasias múltiples. La frecuencia en nuestro servicio fue de 1.6%. Parecería existir alguna relación entre el antecedente de familiar de primer grado con cáncer y segundas neoplasias.
