Se hace camino al andar. Reemigración de latinoamericanos desde España hacia otros países europeos (2006-2018)
Authors: Pérez-Caramés Antía , Domínguez-Mujica Josefina , Ortega-Rivera Enrique 
Published: September 2021

Es sobradamente conocido el impacto migratorio de la crisis económica de 2008 en España: la contracción de la inmigración y el aumento de los flujos de emigración, tanto de españoles como de extranjeros, ya fuera en este último caso por retorno o por reemigración a un tercer país. Con el objetivo de profundizar en esta última tendencia, este artículo dirige su atención a los ciudadanos nacidos en países latinoamericanos que emigraron desde España hacia otros destinos europeos, tratando de demostrar que la reemigración revela una identidad cambiante y resiliente más allá de la crisis. Para ello, esta investigación complementa la aproximación cuantitativa a los flujos de reemigración, con un análisis cualitativo a partir de entrevistas semiestructuradas. Las respuestas y declaraciones de los reemigrantes permiten desvelar las circunstancias, motivaciones y estrategias que guiaron su iniciativa de volver a emigrar, así como sus complejos sentimientos de pertenencia.

Published: September 2021

Introduction and Objectives: Renal papillary necrosis is one of the common causes of obstructive uropathy in diabetic patients. During removal of necrosed renal papilla, many patients were observed to have fluffy necrotic material in the ureter, and renal pelvis, and a few among them present again with recurrent episodes of obstructive uropathy and sepsis following DJ stent removal. Our study aimed to identify the significance of this fluffy necrotic material and its evaluation by histopathological examination (HPE). Materials and Methods: This is a prospective observational study done in our institute by compiling data of 56 patients admitted with obstructive uropathy secondary to renal papillary necrosis who underwent a protocol-based treatment from 2016 to 2019. All these patients underwent initial DJ stenting followed by check flexible ureteroscopy or nephroscopy after 6 weeks. The white, necrotic fluffy material collected during initial DJ stenting or with subsequent flexible ureteronephroscopy was sent for HPE. All these patients were followed up for 1-3 years. Results: Out of 56 patients, 15 patients had fluffy necrotic material in the bladder on initial cystoscopy, of which 1 patient was diagnosed with aspergillosis and 1 patient with candida infection on HPE. During check flexible ureteroscopy (FU), 19 patients had minimal burden of fluffy necrotic material in renal pelvis, of which one patient was diagnosed with aspergillosis, one with candida (same patient diagnosed on cystoscopy), and one patient with both aspergillus and candida colonies on HPE. 5 patients had the significant burden of fluffy necrotic material in the renal pelvis, requiring removal via percutaneous nephroscopic access. Among these 5 patients, 2 were diagnosed with aspergillosis and 1 with candida infection on HPE. A total of 32 patients had single papilla, and 24 had multiple papillae in the pelvicalyceal system. 5 out of 7 patients with positive fungal pathology had negative fungal cultures. Compared to our historical data of 4% mortality and 22% recurrent obstructive uropathy in the 3 years preceding the adoption of this protocol, with the present protocol, no patient developed recurrent pyelonephritis during follow-up of 1–3 years after DJ stent removal following complete evacuation of necrotic material and appropriate antifungal treatment. Conclusion: This study highlights the need for check ureterorenoscopy and removal of all necrotic papillae and debris to establish a microbiological and histopathological diagnosis along with proper antifungal treatment to prevent episodes of recurrent pyelonephritis and obstructive uropathy.

Rift Valley fever virus (RVFV) is a mosquito-borne pathogen with
significant human and veterinary health consequences that periodically
emerges in epizootics. RVF causes fetal loss and death in ruminants and
in humans can lead to liver and renal disease, delayed-onset
encephalitis, retinitis, and in some cases severe hemorrhagic fever. A
live attenuated vaccine candidate (DDVax), was developed by the deletion
of the virulence factors NSs and NSm from a clinical isolate, ZH501, and
has proven safe and immunogenic in rodents, pregnant sheep and non-human
primates. Deletion of NSm also severely restricted mosquito midgut
infection and inhibited vector-borne transmission. To demonstrate
environmental safety, this study investigated the replication,
dissemination and transmission efficiency of DDVax in mosquitoes
following oral exposure compared to RVFV strains MP-12 and ZH501.
Infection and dissemination profiles were also measured in mosquitoes 7
days after feeding on goats inoculated with DDvax or MP-12. Hypothesis:
DDVax should infect mosquitoes at significantly lower rates than other
RVF strains and, due to lack of NSm, be transmission
incompetent. Exposure of Ae. aegypti and Cx. tarsalis to
6-8 log plaque forming units (PFU)/mL DDVax by
artificial bloodmeal resulted in significantly reduced DDVax infection
rates in mosquito bodies compared to controls. Plaque assays indicated
negligible transmission of infectious DDVax in Cx. tarsalis
saliva (1/140 sampled) and none in Ae aegypti saliva (0/120).
Serum from goats inoculated with DDVax or MP-12 did not harbor
detectable infectious virus by plaque assay at 1, 2, or 3
days-post-inoculation; infectious virus was, however, recovered from
mosquito bodies that fed on goats vaccinated with MP-12 (13.8% and
4.6%, respectively), but strikingly, DDvax positive mosquito bodies
were greatly reduced (4%, and 0%, respectively). Furthermore, DDVax
did not disseminate to legs/wings in any of the goat-fed mosquitoes.
Collectively, these results are consistent with a beneficial
environmental safety profile .

Published: September 2021

In Azospirillum brasilense, an extra-cytoplasmic function sigma
factor (RpoE10) shows the characteristic 119 amino acid long C-terminal
extension found in ECF41-type sigma factors, which possesses three
conserved motifs (WLPEP, DGGGR, and NPDKV), one in the linker region
between the sigma and sigma , and
the other two in the SnoaL_2 domain of the C-terminal extension. Here,
we have described the role of the two conserved motifs in the SnoaL_2
domain of RpoE10 in the inhibition and activation of its activity,
respectively. Truncation of the distal part of the C-terminal sequence
of the RpoE10 (including NPDKV but excluding the DGGGR motif) results in
its promoter’s activation suggesting autoregulation. Further truncation
of the C-terminal sequence up to its proximal part, including NPDKV and
DGGGR motif, abolished promoter activation. Replacement of NPDKV motif
with NAAAV in RpoE10 increased its ability to activate its promoter,
whereas replacement of DGGGR motif led to reduced promoter activation.
We have explored the dynamic modulation of sigma2 – sigma4 domains and
the relevant molecular interactions mediated by the two conserved motifs
of the SnoaL2 domain using molecular dynamics simulation. The analysis
enabled us to explain that the NPDKV motif located distally in the
C-terminus negatively impacts transcriptional activation. In contrast,
the DGGGR motif found proximally of the C-terminal extension is required
to activate RpoE1

Objective: To identify the pathogens and compare the clinical
characteristics between different type pathogen infection among children
with community-acquired pneumonia (CAP) requiring bronchoalveolar
lavage. Study design: Children <14 years old hospitalized with
CAP requiring bronchoalveolar lavage were enrolled between February 2019
to January 2020. Multiplex reverse transcription polymerase chain
reaction (mRT-PCR) and loop-mediated isothermal amplification (LAMP)
were used for pathogen detection. The demographic and clinical
characteristics were compared between different type pathogen infection
groups. Results: Among 1166 children studied, ≥1 pathogen was detected
in 1084 (93.0%) children and co-infection was detected in 215 (18.4%)
children. Mycoplasma pneumoniae, Streptococcus pneumoniae and adenovirus
were the most frequently detected pathogens. Children infected with
atypical bacteria alone were older and more likely to display a fever,
cough, decreased breath sounds, consolidation, single lobar
infiltration, mucosal erosion and/or necrosis and plastic bronchitis.
Children with virus-atypical bacteria co-infection were more prone to
manifest fatigue, chest pain, tachypnea, chest indrawing, and mucosal
erosion and/or necrosis. Those infected with virus alone or co-infected
with ≥3 pathogens were liable to display changes in bronchial
morphology. Conclusions: Pathogens were detected in 93.0% of enrolled
children. M. pneumoniae infection might be the greatest pediatric
disease burden due to CAP in North China. Keywords: Children;
community-acquired pneumonia; bronchoalveolar lavage fluid; etiology;
co-infection.
Linguistic Philosophy in the Context of the Anthropological Turn of Culture
Authors: SLABOUZ Viktoriia , BUTKO Yuliia , MOZHOVYI Leonid , NIKITINA Nataliia , MATORYNA Nataliia 
Published: September 2021

The article considers the role of the ideas of linguistic philosophy in the context of the anthropological turn of culture that happened in the middle of the 20th century. Culture has constantly been developing on the horizon of man, and all its initiations have always met at the point of “life of man”, which is impossible without language as an essential anthropological attribute of man. The purports of linguistic philosophy (ordinary language philosophy) are relevant as never before. The study presented is based on the phenomenology of Nietzsche’s ideas of returning a new European thought to the origins of modern culture –the idea of a sovereign individual, which is determined by power over himself and his destiny, the ideas of the representatives and founders of linguistic philosophy, the slogan by I. Kant “Sapere aude!” (“Dare to think for yourself!”), on the historical excursus concerning the origin of the term “anthropological turn”. The anthropological turn in the culture of the 20th century together with the purports of linguistic philosophy brought back and developed further the main idea of new European culture – the idea of the self-worth of life, individuality, and freedom. These events gave a new value meaning to this idea.

Published: September 2021

Abstract
The purpose of this paper is to present differences in the perception of current and desired organizational culture between two different types of workers – academic and administrative staff – in non-public universities in Poland. A synthetic review of the literature on organizational culture at universities and the workplace attitudes of the two groups of university employees was conducted and presented. Research in the form of a survey based on Cameron and Quinn's model was conducted in three non-public universities in Poland. A sample of opinions of 115 workers was gathered and analyzed. It was found in the study that according to academic workers, the present culture was market culture, whereas for administrative workers, it was hierarchy culture. Both groups chose clan culture as the preferred culture. The findings may be useful for higher education decision makers in their attempts to transform universities into market-oriented, yet friendly workplaces. The study's limitations include a relatively small sample of respondents. A further, more comprehensive research into the subject will be worth conducting.

Published: September 2021

Abstract
The rapid development of retail and e-commerce is forcing marketing and logistics to be competitive and adapt to the demands of end-customers. At the same time, accurately determining the demand for goods allows to better understand customers and plan deliveries. The purpose of this article is to study the change in patterns of probability of choosing the option to purchase goods among end-consumers with and without the presence of e-commerce. The study consisted of research buyers, determining the probability of purchasing goods from “consumer basket” in the traditional way and over the Internet, which is considered for the example of one of the Kharkiv districts. The results develop e-commerce potential in Ukraine and are intended to determine the motives of consumers when choosing a shopping option.

Abstract
This research introduces a new novel method for mathematically optimizing team sport training models to enhance two measures of athletic performance using an evolutionary computation based approach. A common training load model, consisting of daily training load prescriptions, was optimized using an evolutionary multi-objective algorithm to produce improvements in the mean match-day running intensity across a competitive season. The optimized training model was then compared to real-world observed training and performance data to assess the potential improvements in performance that could be achieved. The results demonstrated that it is possible to increase and maintain a stable level of match-day running performance across a competitive season whilst adhering to model-based and real-world constraints, using an intelligently optimized training design compared a to standard human design, across multiple performance criteria (BF+0 = 5651, BF+0 = 11803). This work demonstrates the value of evolutionary algorithms to design and optimize team sport training models and provides support staff with an effective decision support system to plan and prescribe optimal strategies to enhance in-season athlete performance.
Validation of Velocity Measuring Devices in Velocity Based Strength Training
Authors: Menrad Thorben , Edelmann-Nusser Jürgen 
Published: September 2021

Abstract
To control and monitor strength training with a barbell various systems are on the consumer market. They provide the user with information regarding velocity, acceleration and trajectory of the barbell. Some systems additionally calculate the 1-repetition-maximum (1RM) of exercises and use it to suggest individual intensities for future training. Three systems were tested: GymAware, PUSH Band 2.0 and Vmaxpro. The GymAware system bases on linear position transducers, PUSH Band 2.0 and Vmaxpro base on inertial measurement units. The aim of this paper was to determine the accuracy of the three systems with regard to the determination of the average velocity of each repetition of three barbell strength exercises (squat, barbell rowing, deadlift). The velocity data of the three systems were compared to a Vicon system using linear regression analyses and Bland-Altman-diagrams.
In the linear regression analyses the smallest coefficient of determination (R2.) in each exercise can be observed for PUSH Band 2.0. In the Bland-Altman diagrams the mean value of the differences in the average velocities is near zero for all systems and all exercises. PUSH Band 2.0 has the largest differences between the Limits of Agreement. For GymAware and Vmaxpro these differences are comparable.

Abstract
Temperature difference between supply and return distribution medium (water) is a vital factor when assessing the efficiency of a district heating (DH) substation. An accounting for fluctuations and differences of the heat consumption/generation is the key problem in planning DH system operation. The influence of the fluctuating energy consumption on a DH system was studied with actual data, using the DH systems of the Russian cities Krasnoyarsk and Omsk as a case study. Information is visualized in the form of graphs and charts, orderly and clearly comparing certain points. The data includes supply and return temperatures, and heat demand. Clearly visible state of high return temperatures induces more bottleneck problems as the flow increases. At the same time, in 2019, the total heat demand was 21 008 MW. This is more than 5 % than in 2020, assuming 100 % of consumers connected. The reasons for this trend are: decreasing total housing area, no incentive for the buildings in newly built-up areas to be connected to the DH system, poor service motivating business facilities to disconnect from the system. When the primary energy consumption related to the warmer climate and behaviour of business sector decreases, the DH system requires renovation. It is possible to reduce network return temperature during some months of the year. The reason is that, a high temperature difference is essential to maintain high efficiency and minimize fuel and pumping cost, it also enables more customers to be connected to a DH system without increasing pipe dimensions of a network.

Published: September 2021

Objectives:
The PRECICE system is an implantable limb lengthening intramedullary nail with remotely magnetically controlled distractors indicated for limb length discrepancy (LLD) and short stature treatment. This study reports the initial experience of the Kuwaiti deformity correction unit in utilizing the PRECICE system.

Methods:
Ten patients (four females and six males) were included in this study. All cases were operated using the PRECICE nail system (five antegrade femoral nails, three retrograde femoral nails, and two tibial nails). All surgeries were performed during January 2019 to February 2020.

Results:
The mean age of participants was 20 years (12–33 years), with a 21.6 kg/m2 mean body mass index (17–28). LLD etiologies (mean LLD = 39 mm) were congenital (n = 2), developmental (n = 2), post-traumatic non-union (n = 1), post-traumatic malunion (n = 1), post-traumatic physeal arrest (n = 1), and post-deformity correction and lengthening of the contralateral side with circular frame (n = 3). The mean distraction rate was 0.97 mm/day (range: 0.75–1.2 mm/day). Mean lengthening was 39 mm (range: 20–60 mm). Healing was confirmed at 76 days on average (range: 50–120 days). All patients reached full consolidation to regenerate bone, normal alignment, and normal joint orientation. Antegrade femur lengthening was done in five patients. One patient with a previous knee fixed flexion deformity of 25° improved to a 5° lag of extension. No complications were observed during the lengthening procedures. All the patients were followed up for a minimum of 12 months.

Conclusion:
The PRECICE nail system was successful in lengthening cases with different etiologies, achieving target lengths without complications. All the patients had reported excellent functional outcomes.
