Authors: Agarwal Ajay
Published: May 2021

The recent outbreak of an infectious novel coronavirus disease 2019 (nCoV-19) is significantly influencing the lifestyle of everyone all over the world. A pandemic that has not only claimed countless lives of people across the globe but also has struck the plain and tranquil psychological landscape of the world citizens. COVID-19’s hit on the landscape has resulted in a ripple effect witnessed across the minds of people across the globe. In this paper, we aim to study this ripple effect in terms of the variations caused by the psychological stress of individuals. Stress is the basic gateway to most of the other psychological disorders, as a result, a comprehensive psycholinguist and psychoacoustic study are conducted.This analysis is conducted for students and migrant workers for their distinctive online and offline behavioral activity. Finally, neurobiological insights regarding the implication and necessity of such studies are provided in the field of psychology and neuroscience.
Top Down or Bottom Up? Evidence From the Longitudinal Development of Global and Domain-Specific Self-Esteem in Adulthood
Authors: Rentzsch Katrin , Schröder-Abé Michela
Published: May 2021

Classical theoretical perspectives have implied that either global self-esteem has an impact on domain-specific self-esteem (top-down) or domain-specific self-esteem affects global self-esteem (bottom-up). The goal of the present research was to investigate whether classical top-down and bottom-up approaches could withstand a thorough test. To do so, we applied elaborate analytical methods in a 4-wave longitudinal study across 6 years with preregistered hypotheses and data analyses. We analyzed data from N = 1,417 German participants (30.6% men, median of 12 to 13 years of education) with an average age of 47.0 years (SD = 12.4, Range 18 to 88) at intake. Analyses using latent variable approaches for modeling intraindividual change provided evidence of top-down effects only. For example, participants with higher global self-esteem exhibited an increase in performance self-esteem but not vice versa. Our results also provided evidence of “vertical” associations between global and domain-specific self-esteem, that is, parallel development within the same time frame. In addition, the analyses revealed high rank order stability and a substantial trait component in global self-esteem and the self-esteem domains. The present findings have important theoretical and practical implications for the stability and development of self-esteem in adulthood and advance the understanding of global and domain-specific self-esteem in personality theory.

Authors: Poudel Shiva Prasad
Published: May 2021

This study attempts to examine the relationship between service quality dimensions (tangibility, reliability, responsiveness, assurance and empathy) and students’ satisfaction. Furthermore, this study is also examining critical factors in service quality dimensions (tangibility, responsiveness, reliability, assurance and empathy) that contribute most to the satisfaction of the students. The study employed both purposive and stratified sampling technique by using a set of questionnaires that was distributed to 120 college students in three of the colleges (Balkumari College, Saptagandaki Campus and Birendra Multiple Campus) in Chitwan. However the study found that there is a positive significant relationship between service quality dimensions and students’ satisfaction. The study also found that Empathy has significant relationship with student’s satisfaction in the students’ perception of service quality rendered by their colleges. Finally the study concludes that assessing level of satisfaction and continuous improvements of the quality of services that colleges provide to their students will help management and other staff of these colleges to reach organizational success.
„Miałem dziś przedziwny sen…”. Arte e amore w onirycznych zapiskach Dziennika 1957–1958 Gustawa Herlinga-Grudzińskiego
Authors: Woźniak-Łabieniec Marzena
Published: May 2021

Celem niniejszego artykułu jest omówienie wątków onirycznych w Dzienniku 1957-1958 Gustawa Herlinga-Grudzińskiego. Opisy snów ujawniają tę część duchowej biografii pisarza, która dochodzi do głosu z podświadomości. Sen odgrywa ważną rolę w ukazaniu najgłębszych przeżyć i stanów psychicznych podmiotu mówiącego. Zapisy snów ujawniają więcej, niż autor relacjonuje o sobie bezpośrednio. Pomagają zinterpretować ukryte emocje podmiotu, jego stan ducha, ujawniają stłumione treści psychiczne, będące wynikiem bolesnych osobistych doświadczeń. Dotyczą najistotniejszych dla pisarza tematów, takich jak twórczość artystyczna (natchnienie i proces powstawania dzieła)  oraz  miłość do pierwszej żony Krystyny.
„Bękarty wojny”. Włoskie reminiscencje w pisarstwie Artura Międzyrzeckiego
Authors: Jochemczyk Mariusz
Published: May 2021

Artykuł odtwarza proces jednostkowej, osobistej „pracy pamięci”. Rzecz dotyczy śladów zbiorowego oraz indywidualnego doświadczenia żołnierskiego (coś na kształt: post-traumatic stress disorder) – w literackim zapisie. Ciekawi mnie, jak trauma wojenna włoskiej kampanii krzepnie – jeśli tak można rzec – „narratologicznie”, jak „opowiada się” w zmiennych fazach przedstawienia. Jak ten migotliwy proces („utrwalania” doświadczenia i „zamazywania” go,  „konstruowania losu” i „zaprzeczania rzeczywistemu”, „mitologizowania faktów” i „wypierania realnego”) tekstowo przebiega, jak opalizuje w kolejnych twórczych przekształceniach.

Remote Work and Employment Dynamics under Covid-19: Evidence from Canada
Authors: Gallacher Guillermo , Hossain Iqbal
Published: May 2021

We find that 41 percent of jobs in Canada can be performed remotely, with significant variation across provinces, cities and industries. We complement this with labor micro data and document facts on the relationship between remote work feasibility and income inequality, gender, age and other worker characteristics. We then show that workers in occupations less likely to be able to work remotely experienced larger employment losses between February and March but not between March and April. This suggests that the pandemic shock hit harder and sooner those workers that could not work from home. As the crisis spread to the rest of the economy, the speed of job destruction converged across occupations, in line with occupation/sector complementarities and input-output linkages.
Pakistan's Transition to Civilian Rule: Analysis of Zia Years
Authors: Khan Adil , Imran Muhammad , Nazakat
Published: May 2021

Existing literature on democratization suggests that societies once exposed to democratic liberties develop a deep spirit of resistance. This spirit of resistance is manifested in various movements for the restoration of democracies whenever democratic liberties are taken away by military dictatorships. This paper investigates this spirit of resistance during General Zia's era. It is argued here that eleven years of the militarys' control was challenged on different fronts by the society and finally compelling it to step back and surrender political space to the political elites. Arguments for this paper are developed by reviewing and critically analyzing the mainstream academic works produced about Zia years.
Investigating Matriarchal Mimicry of Patriarchy in a Pakistani Novel
Authors: Akram Zainab , Khan Saima Yousaf
Published: May 2021

In an Eastern society, the institution of matrimony is influenced by social, cultural, psychological, emotional, religious and familial influences. Using concepts of "mimicry" and "the Other" under theoretical stances of mimicry by Bhaba (1994) and "the Other" by Simone De Beauvoir (1956), How it Happened (2013) is investigated in this study. These frameworks explicate the violation and suppression of women in terms of matrimonial affairs in the novel. The findings revealed that the elderly female characters mimic the patriarchal norms by extending them to the next level through matriarchy. It is found that the matriarchy by the elder female characters is authoritative, unchallenged and influential that even the male characters in the novel cannot interfere in the female jurisdiction in matrimonial decisions and verdicts. However, the analysis also revealed that there was sexism in terms of matrimonial choices in which male had the freedom to choose while the female had none.
Balancing task sensitivity with reliability for multimodal language assessments

OBJECTIVE

Intraoperative tasks for awake language mapping are typically selected based on the language tracts that will likely be encountered during tumor resection. However, diminished attention and arousal secondary to perioperative sedatives may reduce a task’s usefulness for identifying eloquent cortex. For instance, accuracy in performing select language tasks may be high preoperatively but decline in the operating room. In the present study, the authors sought to identify language tasks that can be performed with high accuracy in both situational contexts so the neurosurgical team can be confident that speech errors committed during awake language mapping result from direct cortical stimulation to eloquent cortex, rather than from poor performance in general.

METHODS

We administered five language tasks to 44 patients: picture naming (PN), text reading (TR), auditory object naming (AN), repetition of 4-syllable words (4SYL), and production of syntactically intact sentences (SYNTAX). Performance was assessed using the 4-point scale of the quick aphasia battery 24 hours preoperatively and intraoperatively. We next determined whether or not accuracy on each task was higher preoperatively than intraoperatively. We also determined whether 1) intraoperative accuracy on a given task predicted intraoperative performance on the other tasks and 2) low preoperative accuracy on a task predicted a decrease in accuracy intraoperatively.

RESULTS

Relative to preoperative accuracy, intraoperative accuracy declined on PN (3.90 vs 3.82, p = 0.0001), 4SYL (3.96 vs 3.91, p = 0.0006), and SYNTAX (3.85 vs 3.67, p = 0.0001) but not on TR (3.96 vs 3.94, p = 0.13) or AN (3.70 vs 3.58, p = 0.058). Intraoperative accuracy on PN and AN independently predicted intraoperative accuracy on the remaining language tasks (p < 0.001 and p < 0.01, respectively). Finally, low preoperative accuracy on SYNTAX predicted a decrease in accuracy on this task intraoperatively (R2 = 0.36, p = 0.00002).

CONCLUSIONS

While TR lacks sensitivity in identifying language deficits at baseline, accuracy on TR is stable across testing settings. Baseline accuracy on the other four of our five language tasks was not predictive of intraoperative performance, signifying the need to repeat language tests prior to stimulation mapping to confirm reliability.
Minimally invasive anteroposterior combined surgery using lateral lumbar interbody fusion without corpectomy for treatment of lumbar spinal canal stenosis associated with osteoporotic vertebral collapse
Authors: Fukuda Kentaro , Katoh Hiroyuki , Takahashi Yuichiro , Kitamura Kazuya , Ikeda Daiki
Published: May 2021

OBJECTIVE

Various reconstructive surgical procedures have been described for lumbar spinal canal stenosis (LSCS) with osteoporotic vertebral collapse (OVC); however, the optimal surgery remains controversial. In this study, the authors aimed to report the clinical and radiographic outcomes of their novel, less invasive, short-segment anteroposterior combined surgery (APCS) that utilized oblique lateral interbody fusion (OLIF) and posterior fusion without corpectomy to achieve decompression and reconstruction of anterior support in patients with LSCS-OVC.

METHODS

In this retrospective study, 20 patients with LSCS-OVC (mean age 79.6 years) underwent APCS and received follow-up for a mean of 38.6 months. All patients were unable to walk without support owing to severe low-back and leg pain. Cleft formations in the fractured vertebrae were identified on CT. APCS was performed on the basis of a novel classification of OVC into three types. In type A fractures with a collapsed rostral endplate, combined monosegment OLIF and posterior spinal fusion (PSF) were performed between the collapsed and rostral adjacent vertebrae. In type B fractures with a collapsed caudal endplate, combined monosegment OLIF and PSF were performed between the collapsed and caudal adjacent vertebrae. In type C fractures with severe collapse of both the rostral and caudal endplates, bisegment OLIF and PSF were performed between the rostral and caudal adjacent vertebrae, and pedicle screws were also inserted into the collapsed vertebra. Preoperative and postoperative clinical and radiographical status were reviewed.

RESULTS

The mean number of fusion segments was 1.6. Walking ability improved in all patients, and the mean Japanese Orthopaedic Association score for recovery rate was 65.7%. At 1 year postoperatively, the mean preoperative Oswestry Disability Index of 65.6% had significantly improved to 21.1%. The mean local lordotic angle, which was −5.9° preoperatively, was corrected to 10.5° with surgery and was maintained at 7.7° at the final follow-up. The mean corrective angle was 16.4°, and the mean correction loss was 2.8°.

CONCLUSIONS

The authors have proposed using minimally invasive, short-segment APCS with OLIF, tailored to the morphology of the collapsed vertebra, to treat LSCS-OVC. APCS achieves neural decompression, reconstruction of anterior support, and correction of local alignment.

Published: May 2021

As a result of four-year research, the patterns of soil processes development depending on the parameters of reclamation load were established. It was established that at the end of vegetation season irrigation of crops with water with high mineralization leads to deterioration of soil structure, where the largest amount of aggregates >10 mm (42.67%) was observed during disk tillage (a similar trend was observed for aggregates <0.25 mm). On average, during 2016-2019, under the influence of irrigation, the transformation of the ionic composition of the aqueous extract led to a change in the chemistry of salinity from sodium chloride-sulfate to calcium-sodium sulfate in all variants, regardless of the studied factors. The most favorable conditions for the formation of the yield in the experiment were created under a differentiated system of tillage with one split for crop rotation and with the introduction of increased doses of fertilizers, which per 1 ha of crop rotation area provided the highest productivity, which was for corn 15.49 t/ha, sorghum - 8.72 t/ha, wheat winter - 7.07 t/ha, and only for soybeans the best conditions this year were created for 1 option - 4.27 t/ha. The highest level of profitability from 1 ha of crop rotation area was obtained for the average fertilization background 2 (N120P52,5 ) for differentiated tillage - 199%, while for other tillage systems and fertilizer doses it decreased to 33-189%.

Published: May 2021

Strane, a posebno invazivne vrste često imaju negativan učinak na biološku raznolikost, ekonomiju, pa i ljudsko zdravlje. One su sposobne
proizvoditi produktivno potomstvo i posjeduju potencijal širenja na značajnim površinama. Stoga je širenje invazivnih vrsta jedno od najvećih problema u zaštiti prirode. Praćenje rasprostranjenosti i procjena rizika invazivne vaskularne flore Požeške kotline vršeno je tijekom ljetnih mjeseci od 2017. do 2019. godine putem kombinirane procjene brojnosti i pokrovnosti. Istraživanjima je utvrđeno ukupno 34 invazivne svojte vaskularne flore kojima je pridružena porodica, životni
oblik, geografsko porijeklo te je procjenjena faza procesa invazije. Za
analizu povezanosti između nadmorske visine i pokrovnih vrijednosti invazivne flore Požeške kotline, primjenjena je multivarijantna statistička tehnika - CCA analiza. Najbrojnije vrstama su porodice Asteraceae i Poaceae. Analiza životnih oblika izdvojila je dominaciju terofita, ali i prisutnost hemikriptofita, fanerofita, geofita i hidrofita. Po porijeklu invazivne biljke pronađene u Požeškoj kotlini dolaze prvenstveno sa američkog područja, posebice Sjeverne Amerike, a zatim slijede one iz Azije i Afrike. Većina zabilježene invazivne flore nalazi se u stadiju ekspanzije tj. kolonizacije. Dobar dio je već naturaliziran, a dio je u fazi introdukcije. Nizinska područja do 200 m nadmorske visine pogoduju najvećem broju invazivnih biljaka. Samo manji broj biljnih vrsta je pozitivno koreliran s brežuljkastim područjima gdje se ističu vrste Phytolacca americana L. i Ailanthus altissima (Mill.) Swingle. Najviše zahvaćeni invazijom su ruderalna i poljoprivredna staništa.
Çocuk Adam: Şairin tek romanı veya nostaljiyle kurgulanmış bir otobiyografi
Authors: YİĞİTLER Şener Şükrü
Published: May 2021

Orhan Seyfi Orhon Türk edebiyatında şiirleri ve gazete yazılarıyla tanınan ve hecenin beş şairinden biri olarak yerini koruyan önemli bir isimdir. Edebiyatın çeşitli türlerinde eserler veren Orhon’un şiirleri, mizah ve hiciv hikâyeleri, fıkraları ve biyografilerinin yanı sıra Çocuk Adam (1941) adlı bir romanı da vardır. Orhon’un, edebiyat tarihçilerinin ve araştırmacıların ilgisinden mahrum kalan bu tek romanı, taşıdığı yoğun biyografik içerik ve sanatçının hayatından manzaraları, hayat görüşünü ve sanat anlayışını sergilemesi bakımından önemlidir. Bunun yanında, Orhon’un, romanın adının da çağrıştırdığı çocukluk, çocuk kalmak, büyümek üzerine düşüncelerine yer verdiği roman, derin nostalji duygusuyla dikkati çeker. Şiirlerindeki canlı lirizm etkisiyle tanınan şairin bu eserinde roman sanatının elverdiği içerik ve teknik unsurlardan faydalandığı görülür. Romanının içeriksel malzemesini oluşturan geçmişi, canlı, devam eden ve bugünle bağlantısı olan bir cevher olarak değerlendirir. Nostaljik yanılsamanın etkisiyle hafıza, çocukluk, ev, kaybedilen masumiyete özlem gibi temaları işlerken geçmişi ve romanının otobiyografik malzemesini yeniden kurgular. Ancak daha ilgi çekici biçimde Orhon, 1965’te yapılan ikinci baskısında romanının üçüncü bölümünü tümüyle değiştirir. Bu makalede, Orhon’un başta bir rüya âlemi olarak çocukluğu sonradan kötülük tohumlarının atıldığı bir çağ olarak hatırlamasının yanı sıra, onu romanının en çarpıcı sahnelerini içeren üçüncü bölümü yeniden yazmaya iten muhtemel kurgusal, psikolojik nedenler ve toplumsal şartlar tartışılmıştır.

Via2G Microtransit Pilot Evaluation
Authors:   University of Oregon, Brown Anne , Grossman Alice ,   Mineta Transportation Institute, Noble Lucy ,   Mineta Transportation Institute
Published: May 2021

Google partnered with Via to launch an on-demand microtransit called Via2G between January and March 2020. The pilot provided employees with free travel to/from two of its offices in suburban, congested Silicon Valley. While the pilot was cut short due to COVID-19, rider participation grew steadily during operation. Of trip requests, 8,636 (87.8%) resulted in a ride offer. Unfulfilled requests were primarily outside of pilot operating times or when rider demand exceeded driver supply. Most users (72%) completed at least two trips, although recurring users were less likely to complete errands on the commute and fewer had a car available for commuting compared to all surveyed Google employees. Prior to Via2G, two-thirds (66%) of survey respondents drove to work at least one day per week, while a plurality (42%) drove five days per week. Compared to non-participants, pilot users were more likely to take ride-hail (14 vs 22 percent) or the Google Bus (24 vs 30 percent) at least once a week prior to the pilot. Recommendations suggest iterations for Google or other centralized employers to consider in future microtransit programs.
Human Factors and Requirements of People with Cognitive Impairment, Their Caregivers, and Healthcare Professionals for mHealth Apps Including Reminders, Games, and Geolocation Tracking: A Survey-Questionnaire Study
Authors: Lazarou Ioulietta , Stavropoulos Thanos G. , Mpaltadoros Lampros , Nikolopoulos Spiros , Koumanakos George , Tsolaki Magda , Kompatsiaris Ioannis (Yiannis)
Published: May 2021

Background:

Mobile Health (mHealth) apps can delay the cognitive decline of people with dementia (PwD), by providing both objective assessment and cognitive enhancement.

Objective:

This patient involvement survey aims to explore human factors, needs and requirements of PwD, their caregivers, and Healthcare Professionals (HCPs) with respect to supportive and interactive mHealth apps, such as brain games, medication reminders, and geolocation trackers through a constructive questionnaire.

Methods:

Following the principles of user-centered design to involve end-users in design we constructed a questionnaire, containing both open-ended and closed-ended questions as well as multiple choice and Likert scale, in order to investigate the specific requirements and preferences for mHealth apps. We recruited 48 participants including people with cognitive impairment ( n = 15), caregivers ( n = 16), and HCPs ( n = 17) and administered the questionnaire.

Results:

All participants are likely to use mHealth apps, with the primary desired features being the improvement of memory and cognition, assistance on medication treatment, and perceived ease to use. HCPs, caregivers, and PwD consider brain games as an important technology-based, non-pharmaceutical intervention. Both caregivers and patients are willing to use a medication reminder app frequently. Finally, caregivers are worried about the patient wandering. Therefore, global positioning system tracking would be particularly important to them. On the other hand, patients are concerned about their privacy, but are still willing to use a geolocation app for cases of emergency.

Conclusion:

This research contributes to mHealth app design and potential adoption. All three groups agree that mHealth services could facilitate care and ameliorate behavioral and cognitive disturbances of patients.

Background:

The Australian Imaging, Biomarkers and Lifestyle (AIBL) Study commenced in 2006 as a prospective study of 1,112 individuals (768 cognitively normal (CN), 133 with mild cognitive impairment (MCI), and 211 with Alzheimer’s disease dementia (AD)) as an ‘Inception cohort’ who underwent detailed ssessments every 18 months. Over the past decade, an additional 1247 subjects have been added as an ‘Enrichment cohort’ (as of 10 April 2019).

Objective:

Here we provide an overview of these Inception and Enrichment cohorts of more than 8,500 person-years of investigation.

Methods:

Participants underwent reassessment every 18 months including comprehensive cognitive testing, neuroimaging (magnetic resonance imaging, MRI; positron emission tomography, PET), biofluid biomarkers and lifestyle evaluations.

Results:

AIBL has made major contributions to the understanding of the natural history of AD, with cognitive and biological definitions of its three major stages: preclinical, prodromal and clinical. Early deployment of Aβ-amyloid and tau molecular PET imaging and the development of more sensitive and specific blood tests have facilitated the assessment of genetic and environmental factors which affect age at onset and rates of progression.

Conclusion:

This fifteen-year study provides a large database of highly characterized individuals with longitudinal cognitive, imaging and lifestyle data and biofluid collections, to aid in the development of interventions to delay onset, prevent or treat AD. Harmonization with similar large longitudinal cohort studies is underway to further these aims.

Published: May 2021

Transport calculations for neutronic design require accurate nuclear data and validated computational tools. In the Spallation Physics Group, at the European Spallation Source, we perform shielding and neutron beam calculations to help the deployment of the instrument suite for the current high brilliance (top) moderator, as well for the design of the high intensity bottom moderator, currently under study for the facility. This work includes providing the best available nuclear data in addition to improving models and tools when necessary. In this paper we present the status of these activities, which include a set of thermal scattering kernels for moderator, reflector, and structural materials, the development of new kernels for beryllium considering crystallite size effects, nanodiamonds, liquid hydrogen and deuterium based on path integral molecular dynamics, and the use of the software package NCrystal to assist the development of nuclear data in the framework of the new HighNESS project.

Published: May 2021

Stem cells offer a promising therapeutic strategy to not only treat several incurable diseases but also regenerate damaged tissues. The current global boom in the field of stem cell and regenerative therapies had led to India becoming a global hotspot for stem cell-based therapies. In this review, we assess the current status of stem cell therapy trials in India and show that the bone marrow-derived stem cells, like mesenchymal stem/stromal cells (MSCs), are predominantly used. Phase 1 and 2 clinical trials have also used MSCs to alleviate symptoms of severe novel coronavirus infections. Recent breakthroughs in gene editing technologies, combined with stem cell therapy, can be effectively harnessed to devise large-scale and affordable treatments for haematological diseases that are highly prevalent in India, like beta-thalassemia and sickle cell diseases. Innovations in stem cell therapy in India can make treatments more affordable to address the needs of in-country patients.
Collisions, added mass, speed increase, and energy transfer via quantum entanglement
Authors: Lagutin Boris
Published: May 2021

This paper (preprint) is the author’s analytical research of elastic and inelastic collisions (impacts) of two bodies in a linear motion. An experiment (inelastic collision) described in the paper is designed to understand how an additional mass can physically (not in physical formulas) make a final speed increase of one of two colliding bodies. A first body (big block), which is linearly moving at some constant speed, hits a second body (small block) which is motionless. Accelerations of and final speeds of the blocks, and the impact time are measured. Then, some additional mass is assembled to the big block so that a length of the big block can stay the same. Next, the big block (with an added mass) hits the small block keeping the initial speeds of the blocks the same. Accelerations of and final speeds of the blocks, and the impact time are measured. In according to the classical mechanics formulas, a final speed of the small block gets higher if a total mass of the big block is increased, even though the initial speeds of the blocks do not change. However, it is unclear how a mass, which is added to the big block, may physically make an increase of the small block final speed if the initial speeds of and lengths of the colliding blocks do not change. A speed of shock waves is the same in the two blocks if they are made of the same material. Based on the physics of collision, if a length of the small block is less than a length of the big block, then the small block must begin to move when its shock wave returns to the impact area before a shock wave in the big block returns to the impact area. In other words, the small block must begin to move at the same time in the collision with or without an added mass, so the initial speeds of and lengths of the two blocks do not change. Therefore, the physical impact time must be the same for the collision with or without an added mass. Hence, the blocks cannot squeeze each other faster or longer during the physical impact when an added mass is assembled to the big block. In such conditions, the final speed increase of the small block can physically happen in the way that the small block either gets a higher acceleration or accelerates for a longer time after the physical impact between the blocks (with an added mass) ends. The current physics does not explain how physically (not in the formulas) an added mass can make the small block accelerate faster or longer after the physical impact (contact) ends. Therefore, the current collision physics appears not to explain the collision process completely when the small block final speed becomes higher despite the same impact time. The author assumes that maybe the interactions between the particles in the experimental collision may be based on some sort of quantum entanglement, anisotropy, relativity, that is, without any fields, or the energy transfer between fields happens via some sort of quantum entanglement anisotropically. Though, such an assumption requires a supplementary experimental research.

The objective was to evaluate the production and post-harvest quality of fruit from grafted and non-grafted tomatoes. The experiment was carried out in a randomized block design with five treatments (Jiloeiro, Berinjeleira, Jurubeba, 'Intacto' rootstock and the witness the cherry tomato without grafting) and 16 replicates. In the evaluation of physical-chemical quality, the experiment followed a randomized block design in a 5x2 factorial scheme (rootstocks and storage temperatures, 10 ºC and room temperature) four replications. For a better productive contribution of the cherry tomato, the use of rootstocks from Jurubeba and Intacto is indicated, however, the use of a rootstock did not contribute to the durability and physicochemical characteristics of the fruit. When conditioned at 10 ºC, the fruits showed a better visual and physical-chemical aspect in relation to the ambient temperature, with increased durability of the product in all treatments.

Published: May 2021

Several variants of half division two-dimensional method are proposed, which is the basis of a fundamentally new approach for constructing measuring instruments for sinusoidal or periodic electrical quantities. These measuring instruments are used in the diagnosis of electric power facilities. The most general variant, called midpoint method, is considered. The proposed midpoint method allows you to measure much smaller than using widespread methods, alternating currents or voltages, especially when changing the amplitude of the measured signal in very wide ranges, by 1–2 orders of magnitude. It is shown that using the midpoint method it is possible to suppress sinusoidal or periodic interference in the measuring path, in particular, to measure small alternating current when sinusoidal or periodic interference is 1–2 orders of magnitude higher than the useful signal. Based on the results of comparative tests, it was found that the current measuring device implementing the midpoint method is an order of magnitude more sensitive than the currently used high-precision measuring instruments.

The actual problem of accelerating and reducing the energy costs of the foam concrete slabs heat treatment technological process is considered. It is shown that to solve this problem, it is advisable to use the microwave radiation energy as a heat source. The main advantages of the microwave method of foam concrete slabs heat treatment in comparison with traditional methods are considered. The design of a microwave installation for the foam concrete slabs heat treatment has been developed. The installed microwave radiation sources have energy outputs in the form of a rectangular waveguide openings, which are used as radiating antennas. Huygens-Kirchhoff method was used to calculate the temperature distribution on the foam concrete slab surface; the method of loaded long lines was used to calculate the temperature distribution over the foam concrete slab thickness. A method for measuring the foam concrete slab temperature distribution is proposed. The results of theoretical and experimental temperature distribution studies on the surface and the cross-section of foam concrete slab with a width of 1500 mm, a height of 1000 mm and a thickness of 200 mm, a density of 1000 kg/m3 on the electromagnetic fields oscillation frequency of 2450 MHz are shown. The obtained experimental results showed a high efficiency of using microwave radiation for the foam concrete slabs heat treatment technological processes. Microwave technologies can be used for heat treatment of products made of concrete, reinforced concrete and polymer composite materials.
The method of real-time acoustic measurement of dynamical changes in the speaker’s emotional state
Authors: Savchenko Lyudmila V. , Savchenko Andrey V.
Published: May 2021

In this paper we consider the issues in implementations of interactive voice response systems with remote access. Their efficiency can be improved by automatically analyzing changes in the user's emotional state during the dialogue. In order to measure the indicator of the dynamics of the emotional statein real time, it is proposed to use the effect of sound (phonetic) variability of the user's speech at short intervals (fractions of a minute). The novel method of acoustic measurements in conditions of small samples has been developed based on information-theoretic approach by using a scale-invariant gain-optimized dissimilarity measure of the speech signals in the frequency domain. An example of its practical implementation in soft real time is considered. It is shown that the delay in obtaining the measurement results does not exceed in this case 10–20 sec. The experimental results confirmed the high speed of the proposed method and its sensitivity to changes in the emotional state under the influence of external noise. The proposed method can be used for automated quality control of voice samples of users in unified biometric systems, as well as to improve safety by non-contact identification of potentially dangerous persons with short-term psycho-emotional disorders.
