ACUTE EFFECT OF INTENSITY AND VOLUME DURING STRENGTH TRAINING ON SENSATION OF PLEASURE, RATING OF PERCEIVED EXERTION, AND PAIN IN TRAINED MEN

Purpose. the purposes of this study were: (a) to compare the sensation of pleasure, rating of perceived exertion (RPE), and pain in different volumes (volitional failure [VF] vs. fixed repetitions [FR]), equalizing the intensity; and (b) to compare the sensation of pleasure, RPE, and pain in different intensities (40%, 60%, and 80%) of one-repetition maximum (1RM), with equalization of training volume. Methods. A total of 12 trained men (aged 24.9 ± 4.3 years) performed 3 sets of seated row, leg press 180°, and chest press at 3 different intensities (40%, 60%, and 80% 1RM) for both training strategies (VF vs. FR). Results. there was a decrease in pleasure and an increase in RPE and pain in VF training sessions at intensities of 40% and 60% 1RM compared with FR. However, no difference was observed for the intensity of 80% 1RM for pleasure. A doseresponse effect was revealed in the comparison of intensities for pain and RPE. In turn, no effect was found for pleasure. Conclusions. VF training sessions decreased responses regarding pleasure, as well as increased RPE and perceived pain for the intensities of 40% and 60% 1RM when compared with the same intensity in FR among trained men. Different intensities were not able to change the sensation of pleasure.
Theoretical Astrophysics in the Byurakan Observatory (1946-2021)

The purpose of this review is to give a general idea of the results on theoretical astrophysics investigations carried out at the Byurakan Observatory during the period of its existence. A special place in the review is given to the research work in the Department of ”Theoretical Astrophysics”, founded in 1965. The review consists of two parts. The first part is mainly devoted to works on the theory of radiation transfer somehow related to Ambartsumian’s ideas developed in his fundamental studies of the 40-50s of the last century. The second part presents, on the one hand, the results which are of importance for theoretical physics in general and, on the other hand, gives their application to the interpretation of observational data of various cosmic objects. In order to get an idea of the importance of each result, the background and prerequisites of the research are given, indicating its significance from the point of view of astrophysics. Naturally, the most important results are presented in more detail. At the same time, the review in one way or another includes almost all of the most important results obtained by various members of the department at di fferent times. It should be noted that works on some other areas of theoretical astrophysics are not included in the review, since they are presented in other reviews of this series. I. THEORY OF RADIATIVE TRANSFER
Comparison of Functionally Graded Hip Stem Implants with Various Second-Generation Titanium Alloys

Total hip Arthroplasty (THA) is performed every year at a very high frequency to improve the quality of life of thousands of patients all over the globe. Nevertheless, the expected service life of such surgery remains unsuitable for patients under 50 years old. This is mainly related to stress shielding and the potential adverse tissue reaction to some of the elements of the market-dominant implant materials. In this research, functionally graded (FG) implant designs of several titanium alloys layered with hydroxyapatite (HA) are proposed to provide lower implant stiffness compared to a solid stem to approach the requirements of human bone. Moreover, TNZT (Ti35Nb7Zr5Ta), and TMZF (Ti12Mo6Zr2Fe) second-generation titanium alloys are studied as a replacement for the famous Ti6Al4V alloy to avoid the adverse tissue reactions related to aluminum and vanadium elements. The different FG models are numerically tested using a 3D finite element simulation after virtual implantation in a femur bone under the dynamic load of a patient descending stairs. In the numerical study, the variation in stress distribution and strain energy in a femur bone is assessed for different FG hip stems as well as the axial stiffness of the hip stems. Results indicated an increase in strain energy and von Mises stress in the cortical and cancellous bones using FG hip stems. Additionally, the axial stiffness is reduced for all FG hip stems relative to the commercial Ti6Al4V hip stem.
Maternal Experiences of Home-based Kangaroo Mother Care Following Discharge from a Rural- Urban Health Facility, Nsawam Government Hospital, Ghana

Background: Preterm birth (PTB) is the leading cause of child mortality worldwide and SubSaharan Africa is disproportionately affected. Inadequate access to cost-effective interventions in most poor resource areas threatens to increase preterm birth related mortalities. Kangaroo mother care has proven to be a cost-effective intervention and has reduced death as a result of Original Research Article Cyriaano et al.; AJPR, 7(4): 77-88, 2021; Article no.AJPR. 78231 78 complications of PTB by half. Purpose: This study therefore sought to explore and document the experiences of mothers regarding KMC following discharge from Nsawam Government Hospital. Methods: An exploratory descriptive design was used to collect data from mothers who had preterm births and their experiences of practicing kangaroo mother care at home. Fourteen participants in the Nsawam municipality were purposively selected to participate in the study. Data was analyzed using inductive thematic analyses. Findings: The findings of the study indicated that mothers are encouraged to practice KMC based on the benefits of KMC like provision of warmth, bonding and improvement in growth and development. The study also indicated that support systems available to mothers at home included family, churches, community and healthcare providers. Recommendations: The study recommended that; proper follow-up care should be undertaken by clinicians on mothers practicing KMC especially in their respective home environment to ensure adherence KMC practice experiences in the home.
EFFECT OF MIXTURE PREPARATION IN A DIESEL HCCI ENGINE USING EARLY IN-CYLINDER INJECTION DURING THE SUCTION STROKE

It is becoming increasingly difficult for engines using conventional fuels and combustion techniques to meet stringent emission norms. The homogeneous charge compression ignition (HCCI) concept is being evaluated on account of its potential to control both smoke and NOx emissions. However, HCCI engines face problems of combustion control. In this work, a single cylinder water-cooled diesel engine was operated in the HCCI mode. Diesel was injected during the suction stroke (0° to 20° degrees aTDC) using a special injection system in order to prepare a nearly homogeneous charge. The engine was able to develop a BMEP (brake mean effective pressure) in the range of 2.15 to 4.32 bar. Extremely low levels of NOx emissions were observed. Though the engine operation was steady, poor brake thermal efficiency (30% lower) and high HC, CO and smoke were problems. The heat release showed two distinct portions: cool flame followed by the main heat release. The low heat release rates were found to result in poor brake thermal efficiency at light loads. At high brake power outputs, improper combustion phasing was the problem. Fuel deposited on the walls was responsible for increased HC and smoke emissions. On the whole, proper combustion phasing and a need for a wellmatched injection system were identified as the important needs.
Characterization of vacuum HV microdischarges at HVPTF through X-ray bremsstrahlung spectroscopy

The development of MITICA, the prototype for a neutral beam injector for ITER, drives the interest in investigating high HV insulation in vacuum. The High Voltage Padova Test Facility (HVPTF) is an experimental device with the aim of studying the fundamental processes leading to discharges, offering a framework to develop new diagnostics, models, and mode of operations for MITICA. For this purpose, HVPTF features a vacuum chamber containing two electrodes which can achieve an HV difference up to 800 kV. X-ray bremsstrahlung radiation produced by free charges accelerated by the HV was proven to be a promising monitoring mechanism in the past; as such, two scintillating crystals, a LYSO and a LaBr3, coupled with fast electronics were used to conduct hard X-ray spectroscopy. This work describes a newly custom-developed software tool to analyze the spectroscopy from scintillators and integrate it with the HVPTF analog data. The tool was employed to study two experimental sessions, reaching promising results in the characterization of microdischarges, especially in terms of time resolution. Detection limits imposed by pile-up and other processes were identified and addressed, finding the best range of operation of the two scintillators. The performed study opens the way for the analysis of data obtained in all 2020 and 2021 experimental campaigns, thus giving the possibility to implement future improvements in HVPTF X-ray spectroscopy.
DESIGN OF CUT SLOPES IN OVERCONSOLIDATED CLAYS

The design of clay slopes for long-term stability is discussed in relation to (a) mode of failure, (b) soil test methods, (c) method of analysis, (d) selection of parameters, and (e) time dependency of stability. Failures of slopes in overconsolidated clays can be evaluated based on drained soil parameters with little groundwater drawdown below the cut face. The time dependency of slope failure is hypothesized to be a function of the Terzaghi hydrodynamic lag model. These failure criteria are evaluated for a case history of a cut slope in the western Allegheny Plateau region of New York State. (Author)
Spatial Pattern Changing Analysis of Built-up Due to The New Era of Aerotropolis in Kulon Progo, D.I. Yogyakarta

Built-up is artificial land use representing urban-oriented activities according to the sector developed in the aerotropolis, the development concept of city activity centered on the globally networked economy’s airport. The growth of unplanned built-up often caused environmental deterioration. Therefore, the impact of the emerging of a new growth center to the growth characteristic of the built-up requires to be analyzed. This research aimed to examine the growth and spatial distribution characteristics of built-up to mitigate the undesirable impact on the environment in the early phase of aerotropolis in Kulon Progo. The growth was analyzed using the spatial intersection of land use/land cover. The distribution orientation growth was carried out by weighted mean center and spatial standard deviational ellipse. The results demonstrate that annual growth of built-up increased from 55.35 ha per year in 2010-2015 to 69.83 ha per year in 2015-2020. Dryland agriculture was the most land use converted to built-up after aerotropolis era. The direction of built-up growth also shifted from northwest to southwest, and the distance between the airport and the mean center was getting closer. Therefore, land use planning policy need to refer to this pattern changing to preserve environmental sustainability while achieving economic growth.
On resolving efficient domination number of path and comb product of special graph

We use finite, connected, and undirected graph denoted by G. Let V (G) and E(G) be a vertex set and edge set respectively. A subset D of V (G) is an efficient dominating set of graph G if each vertex in G is either in D or adjoining to a vertex in D. A subset W of V (G) is a resolving set of G if any vertex in G is differently distinguished by its representation respect of every vertex in an ordered set W. Let W = {w 1, w 2, w 3, …, wk } be a subset of V (G). The representation of vertex υ ∈ G in respect of an ordered set W is r(υ|W) = (d(υ, w 1),d(υ, w 2), …, d(υ, wk )). The set W is called a resolving set of G if r(u|W) ≠ r(υ|W) ∀ u, υ ∈ G. A subset Z of V (G) is called the resolving efficient dominating set of graph G if it is an efficient dominating set and r(u|Z) ≠ r(υ|Z) ∀ u, υ ∈ G. Suppose γre (G) denotes the minimum cardinality of the resolving efficient dominating set. In other word we call a resolving efficient domination number of graphs. We obtained γreG of some comb product graphs in this paper, namely Pm ⊲ Pn , Sm ⊲ Pn , and Km ⊲ Pn .
The Effect of Communication and Organizational Climate on Employee Job Satisfaction at PT. Alove Bali

Job satisfaction is a pleasant emotional state of the work the employee produces. In order for employees to have high job satisfaction, an organization needs to pay attention to the factors that influence job satisfaction. The purpose of this study is to determine the effect of communication and organizational climate on employee job satisfaction. This research was conducted at PT. Alove Bali. The number of samples used are 67 employees, with a saturated sample method. Data collected by observation, interviews, and questionnaires. Data analyzed by multiple linear regression. The results of this study found that communication has a positive and significant effect on employee job satisfaction and organizational climate has a positive and significant effect on employee job satisfaction. To improve employee job satisfaction, companies need to pay attention to the communication of employees so that employees are able to complete and be responsible for the tasks given smoothly. The company must also pay attention to the organizational climate so that employees are able to work optimally and have a good organizational climate.
Assessing Metacognition Awareness of Freshmen Engineering Students

An interdisciplinary team of researchers at a Southwest Hispanic-Serving Land-Grant University embarked on an National Science Foundation-funded study to provide workshops for first year engineering students to introduce them to metacognitive awareness learning strategies that have the potential to help their study skills, and in turn, their academic performance. To assess if these strategies were utilized and if they were helpful for students, we collected preand post-intervention surveys and reflective writing journals. The survey items came from the metacognitive awareness inventory (MAI) [1] to measure preand post-knowledge and regulation of cognition. These surveys were administered to the introductory level engineering classes at the beginning and end of their first semester in college in the required introduction to engineering course. In this paper, results pertaining to MAI scores and students’ performance on their first exam scores are presented. A shortened version of the original 52-item MAI survey, now called the Modified Metacognition Awareness Inventory (MMAI) is also statistically analyzed and discussed. Results will be useful for other educators and researchers in engineering who are looking to help students with effective learning strategies and study skills to foster their success in engineering courses and/or other subjects.
Active power filter technology and its development

With the wide application of power electronic switches in power system, more harmonic and reactive current are poured into the power, which caused power pollution. Conventionally passive filters were used to reduce harmonics and reactive power to improve the power factor of the ac loads. However, passive filters have the demerits of fixed compensation, large size and resonance. Thus, the experts and power system engineers now focus on the active power filter. The background, development, classifications and the future prospects of active power filters are presented in this paper. With the developments of technique, active power filters will achieve higher performances and wider applications.
Report on FY15 alloy 617 code rules development

Due to its strength at very high temperatures, up to 950°C (1742°F), Alloy 617 is the reference construction material for structural components that operate at or near the outlet temperature of the very high temperature gas-cooled reactors. However, the current rules in the ASME Section III, Division 5 Subsection HB, Subpart B for the evaluation of strain limits and creep-fatigue damage using simplified methods based on elastic analysis have been deemed inappropriate for Alloy 617 at temperatures above 650°C (1200°F) (Corum and Brass, Proceedings of ASME 1991 Pressure Vessels and Piping Conference, PVP-Vol. 215, p.147, ASME, NY, 1991). The rationale for this exclusion is that at higher temperatures it is not feasible to decouple plasticity and creep, which is the basis for the current simplified rules. This temperature, 650°C (1200°F), is well below the temperature range of interest for this material for the high temperature gas-cooled reactors and the very high temperature gas-cooled reactors. The only current alternative is, thus, a full inelastic analysis requiring sophisticated material models that have not yet been formulated and verified. To address these issues, proposed code rules have been developed which are based on the use of elastic-perfectly plastic (EPP) analysis methods applicable tomore » very high temperatures. The proposed rules for strain limits and creep-fatigue evaluation were initially documented in the technical literature (Carter, Jetter and Sham, Proceedings of ASME 2012 Pressure Vessels and Piping Conference, papers PVP 2012 28082 and PVP 2012 28083, ASME, NY, 2012), and have been recently revised to incorporate comments and simplify their application. Background documents have been developed for these two code cases to support the ASME Code committee approval process. These background documents for the EPP strain limits and creep-fatigue code cases are documented in this report. « less
A MATCH MADE IN HEAVEN: THE INFLUENCE OF CROSS-COUNTRY DIFFERENCES IN CULTURAL TIGHTNESS-LOOSENESS ON CROSS-BORDER ACQUISITION PERFORMANCE

Cross-border acquisitions (CBAs) have massively grown in volume worldwide over the past decades and have attracted frequent academic as well as media attention alike. While research about organizations has a rich history in examining culture’s impact on CBA performance, it has focused almost exclusively on cultural values and neglected other important aspects, namely social norms. Our study addresses this neglect and examines the impact of cultural tightness-looseness (TL)—which refers to the strength of social norms and the degree of sanctioning within societies—on CBA performance. We draw on cultural familiarity theory and hypothesize that TL differences influence the ability of firms to interact across different levels of the merging organizations and, in so doing, hamper the post-deal performance of CBAs. Taking a culture by context perspective that focuses on when cultural differences are most pronounced, we further propose a number of moderators of the TL-CBA relationship, including the direction of TL differences, the absolute level of tightness, industry relatedness, and membership in high-tech industries. Using data for 4,717 CBAs in 30 countries between 1989 and 2013, we find that cross-country differences in TL negatively influence acquirers’ return on assets (ROA) and that this influence is strengthened by the direction of TL, absolute level of tightness, and membership in high-tech industries, above and beyond cultural values differences. Theoretical and practical implications are discussed.
WAGE DIFFERENTIAL BETWEEN PUBLIC AND PRIVATE SECTOR IN SLOVENIA

Using EU-SILC individual-level data, we analyse the public-private sector wage premium in Slovenia in the period from 2004 till 2014 taking into account only occupations that have employees in both, public and private sector (comparable occupations). Because of structural changes in the public sector wages due to public sector wage reform in 2008 and fiscal austerity measures put in place from mid 2012 on, we decompose wage premium in three time sub samples. More specifically, between 2004 and 2008, public sector employees in comparable occupations (after taking into account individual characteristics) were generally marginally underpaid relative to their private sector colleagues (except for the low wage earners), while the 2008 public sector wage reform decreased public-private sector wage disparities. The wage austerity measures in public sector, that were put in place from 2012 onwards, negatively affected public sector workers by making their wages less compelling again. However, the impact varied across occupational groups, making this generalization subject to numerous caveats. Our analysis of the reasons for the difference between public and private sector wages uses the Blinder-Oaxaca decomposition and covers the whole 10-year period. The results show that in most of the low-income occupations the reasons for the public-private sector wage difference are mostly originating from the unobserved characteristics of workers. Whereas in higher wage classes the reasons are coming from the observable characteristics. In one third of occupations in our analysis, the origin for the difference cannot be clearly determined. Moreover, the analysis also highlights the importance of controlling for comparable occupations (i.e. comparing "apples to apples"). Namely, if one fails to exclude incomparable occupational groups from the analysis, the story can give distortional message saying that public sector workers are earning higher wages as compared to their private sector peers and that the pay reform preserved (or even increased) the already positive wage premium of public sector workers and the austerity measures decreased it.
Sustainable Corn Stover removal Systems for Mushroom Substrate Production

Corn stover has been identified as a new potential feedstock for mushroom substrate production. Corn stover removal can increase soil erosion, deplete soil nutrients and reduce soil carbon if not managed appropriately. To mitigate corn stover removal in some situations, agronomists may need to add amendments like spent mushroom substrate (SMS) or mushroom compost (MC) to assist in to managing soil carbon levels. The objective of this study is to measure the effects of a 75% spring corn stover removal, using that stover as an ingredient for mushroom substrate and returning that SMS as an soil amendment to build soil health. The SMS resulted in an increase in soil C levels in the 0-5 cm soil profile by 81%, and 39% in the 0-25 cm soil profile. In the untreated check, where no stover was removed and no SMS added, soil C in the 0-5 cm soil profile declined by 14% and increased in the 0-25 cm soil profile by only 1.3% over the three year study. The combination of SMS addition and stover harvest also resulted in higher corn yields, lower slug populations, increased revenue, and decreased fertilizer inputs over the course of three a years of corn and three years of a hypothetical alfalfa rotation. Net returns were $4653 higher with the combination of stover harvest and SMS addition over the six years compared with the no stover harvest system. Spring and fall stover harvests were compared to evaluate the impact on the yield and nutrient composition of the stover. Spring harvested yields were reduced by 11% in the first year and 43% in the second year of the study compared to fall yields. Stover nutrient concentrations were generally unchanged, except for potassium, which declined from 7.4 to 3.0 g kg-1 or a 59.4% decrease from the fall to the spring. Based on this study, harvest in the spring can reduce nutrient removal and the associated costs and is a viable strategy to reduce the impacts of stover harvest. Overall, this study showed that the combination of partial stover harvest, SMS addition and spring stover harvest could improve returns associated with corn production while maintaining soil carbon levels.
