Published: March 2022

Objectives. Viral bronchiolitis represents one of the main cause of
hospitalization for children in developed and incoming countries. Nasal
High Flow (NHF) oxygen therapy improves oxygenation and reduces
respiratory drive by enhancing carbon dioxide wash-out. However, little
is known about physiological effects of noninvasive helmet-Continuous
Positive Airway Pressure (h-CPAP) and NHF on respiratory Work Of
Breathing (WOB) in bronchiolitis. Objective of the study is to measure
Esophageal Pressure Time Product*minute (PTPes*min-1) as a surrogate for
WOB in acute bronchiolitis during NH at different flow rates in
comparison with conventional h-CPAP. Pressure Rate Product,
physiological parameters and gas exchange were considered as secondary
end-points. Methods. This is a physiological randomized crossover-study
comparing four 20-minute trials: oxygen therapy delivered by non-fitting
mask, NHF2l/Kg, NHF3l/Kg, h-CPAP 7cmH2O. Results. Were enrolled ten
children with bronchiolitis needing noninvasive respiratory support.
PTPes*min-1, Respiratory Rate and Pressure Rate Product decreased
progressively from h-CPAP compared to NHF3l/kg, NHF2l/kg and oxygen mask
(p<0.01 for all parameters). SpO2:FiO2 increased during h-CPAP
versus NHF3l/kg, NHF2l/kg and oxygen mask (p<0.01).
Transcutaneous carbon dioxide tension was affected by increasing flow
rate showing a progressive reduction at NHF3l/kg, NHF2l/kg and during
h-CPAP compared to oxygen mask (p<0.001). Conclusions. h-CPAP
was associated with a reduction in WOB and with a better oxygenation
compared to oxygen mask and NHF trials; 2) NHF trials improved
oxygenation and reduced the carbon dioxide tension compared to oxygen
mask 3) NHF3l/kg does not offer advantages compared to NHF 2 l/kg in
improving oxygenation and carbon dioxide wash-out.
The role of E. maritimum (L.) in the dune pollination network of the Balearic Islands
Authors: Cortes Ivan , Cerrato Marcello , Ribas Arnau , Canyelles Xavier , Gil Lorenzo
Published: March 2022

Eryngium maritimum L. (Apiaceae) is a geophyte that inhabits in the
dunes of the Mediterranean and Atlantic. In Northern Europe, it is
considered a highly endangered species due to reproductive problems,
while in the Mediterranean, populations are in a good state of
conservation. Although it is a highly entomophilous species, there is
little literature on its pollinators. The aim of this study is to
analyse the role played by E. maritimum in the dune pollination network
of the Balearic Islands. For this purpose, two populations located in
the North and South of Mallorca were chosen, in which diurnal transects
were carried out to observe and capture pollinators on 15 plant species
during the anthesis period of E. maritimum. In parallel, an analysis of
the flowering period of 10 of these plant species was carried out to
identify periods of competition. A total of 82 pollinator species were
found, belonging to 30 different families. Eryngium maritimum is a
strongly generalist species, with a total of 46 pollinator species.
Functionally, Teucrium dunense and Helichrysum stoechas are functionally
the most similar species to E. maritimum. However, analysis of phenology
suggests that these three species have been able to decouple their
blooms to avoid competition. The present study shows that E. maritimum
plays a key role in the dune pollination network, being its anthesis
located at the end of the dune flowering season, when there are no
functionally similar species in flower.

Authors: Koppes Dorothea , Snoeren Anniko , Kruitwagen Roy , Scheele Fedde , Schepens-Franke Annelieke , Notten Kim
Published: March 2022

Objective: international validation of the Dutch Delphi consensus study
about which anatomical structures that should be taught to ensure safe
and competent practice among general gynaecologists. Design: Validation
study. Setting: Academic, non-academic teaching and non-academic,
non-teaching hospitals worldwide. Population: Gynaecologists and
trainees in gynaecology. Methods: The relevance of 123 items included in
the Dutch Delphi study was scored on a Likert scale between 1 (not
relevant) and 5 (highly relevant). Consensus was defined when  70% of
the panellist scored the item as relevant or very relevant and the
average rating was  4. Main Outcome Measures: Clinically relevant
anatomical structures. Results: A total of 192 gynaecologists and
trainees from seven countries (Belgium, Germany, Norway, Oceania,
Sweden, United Kingdom and United States) completed the questionnaire.
Of the 123 structures, 72 (58.5%) were internationally relevant. When
the 72 relevant structures from the international Delphi study were
compared with the 86 relevant structures from the Dutch Delphi study, 70
(81.4%) structures matched. Conclusions: This study identified 70
anatomical structures that should be taught for safe and competent
practice of general gynaecologists based on national and international
validation. The results of our study identify the learning needs (i.e.,
the content) for an international anatomy curriculum. The development of
the curriculum (i.e., the form) can be determined by each country and
used to standardize and guide postgraduate training in gynaecology. This
is an important step in the era of international teaching and training.

Published: March 2022

Objective: To compare the laparoscopic enclosed electromechanical
morcellation (LEM) with vaginal enclosed scalpel morcellation (VSM) in
laparoscopic myomectomy procedures. Design: Prospective randomized
interventional clinical study. Setting: Tertiary university hospital.
Population or Sample: One hundred eighteen patients who underwent
laparoscopic myomectomy. Methods: All myomectomy procedures were
performed laparoscopically. After myomectomy, tissue removal was
accomplished via either LEM using the previously described in-glove
morcellation technique or VSM. In the VSM group, myoma was placed into
an endoscopic bag and removed through the vagina via posterior colpotomy
after scalpel morcellation. Main Outcome Measures: Primary outcome:
tissue removal time. Secondary outcome: rescue analgesia requirement,
postoperative Visual Analog Scale (VAS) scores, postoperative 3th month
scores of Female Sexual Function Index (FSFI). Results: The median
tissue removal time was longer in the LEM group (25 min (Range: 14-55))
than the VSM group (20 min (Range: 6-38) (p=.001). Rescue analgesia
requirement was significantly higher in the LEM group than the VSM group
(mean rank: 56.92 vs 40.92 doses, respectively; p<.001). There
was no significant difference between the groups at postoperative VAS
scores. There was no significant difference between preoperative and
postoperative 3th month total scores of FSFI and subdomains in the LEM
group. Conversely, all subdomains and total scores of FSFI (26.5
(16.7-34.8) vs. 22.7 (15.2-28.7) except pain significantly worsened
three months after operation in the VSM group. Conclusion: LEM was
associated with a longer tissue removal time and increased postoperative
analgesic requirement. On the other hand, VSM was associated with
worsened postoperative sexual function from baseline.

Improvement and sensitivity analysis of equivalent heat transfer model for dynamic thermal rating of overhead lines
Authors: Peng Xiangyang , Deng Honglei , Wang Rui , Liu Zhao , Luo Shujian , Guo Deming , Liu Gang
Published: March 2022

With the rapid growth of power demand, the conductor ampacity calculation method based on the dynamic thermal rating (DTR) becomes more and more important. Based on the shortcomings of the current DTR models, a new DTR model that does not need to measure the wind speed and the operating state of conductor is proposed, which is called the equivalent heat transfer (EHT) model. However, there are still shortcomings in the accuracy of the EHT model in application. In this paper, the EHT model is improved at first according to the consideration of the effect of air physical parameters and the redetermination of the experimental parameters of the EHT equipment. Then, the operation of EHT equipment is simulated through the established experimental platform. The improved EHT model is verified by the IEEE standard. Finally, the sensitivity analysis of the improved EHT model is carried out. The results show that the improved EHT model is greatly improved on application accuracy compared to the original EHT model. Moreover, the improved EHT model can choose the steady-state temperature at any position on the surface of the aluminum ball to calculate the conductor ampacity, and the relative error does not exceed 6%. The improved EHT model is reliable and can meet the safe operation requirements of the power system in practical engineering applications.
Numerical analysis and optimization of thermal performance of lithium battery pack based on air-cooling strategy
Authors: Hu Yu , Mao Bin
Published: March 2022

An effective and robust thermal management system can control the temperature of lithium batteries and maintain the long service life and high performance of the module. In this work, the thermal design and optimization of cylindrical battery packs based on air-cooled thermal management strategies are studied. Lumped model is implemented to investigate the thermophysical characteristics of single cell, and the experimental measurements is used to determine the transient heat generation of cylindrical lithium batteries under different discharge rates. On this basis, the CFD method is used to analyze the temperature of the battery pack, and the heat dissipation performance of the air-cooled heat management system is explored. Finally, different air cooling strategies are investigated by changing the area and position of inlet and outlet to obtain the best cooling scheme. The results indicate that the multi-inlet and multi-outlet structure in this paper can significantly lower the temperature and improve the temper-ture uniformity in the battery pack. A better air-cooling performance can be obtained under the optimal parameter configuration, which will help the design of the air-cooled battery thermal management system.

Authors: Hermanucz Peter , Geczi Gabor , Barotfi Istvan
Published: March 2022

In this paper, the investigation of an experimental heat pump equipment is presented. This equipment is capable of serving two different temperature cooling needs and a given temperature heating demand within a given industrial process, adapting to its time and performance requirements. The use of a heat pump is energetically advantageous, if a nearly continuous operation can be realized in the course of an industrial process to serve simultaneous cooling and heating needs. In the field of brewing, it was demonstrated by model experiments that CO2 emissions can be reduced by 60% with a 10% reduction in energy costs if the energy requirements are satisfied using a dual-source heat pump.
Effect of shell on performance of heat exchanger with trefoil-hole baffle
Authors: Wang Yingjia , Du Qingfei , Li Xingchen , Liu Minshan , Liu Zunchao
Published: March 2022

The periodic whole cross-section model and the periodic unit duct model were established, and the differences between two models were discussed. The effects of shell wall and baffle edges on the shell side performance of the heat exchanger with trefoil-hole baffle were investigated using both models. Thermodynamics in the shell side and heat transfer coefficient of each tube in different position were discussed. It is found that disparities between the results of the two numerical models decreases with the increase of the inner shell diameter. When the shell diameter is 0.8 m, the disparity is less than 10%, which means that the effects of the shell wall and the edges of baffles become weaker. When the shell diameter is less than 0.8 m, modified correlations for the periodic unit duct model are introduced to quantitatively reveal the effects of shell wall and baffle edges on thermodynamics with the variations of the shell diameter and baffle spacing. The fluid-flow velocities at specific locations on the shell side were measured using a laser doppler velocimeter system. The accuracy of the numerical simulation method was verified by the experimental results.
Experimental investigation on lift-off, blowout and drop-back in partially premixed LPG open flames in tubular burner
Authors: Abdul Gani
Published: March 2022

The higher pollutant level in non premixed combustion and safety issues
pertaining to premixed combustion can be counteracted by partially-premixed
mode of combustion. The partially premixed flames (PPF) exhibit the benefits
of both premixed and non premixed flames. PPF enhances complete combustion
leading to reduced soot formation and hence lower emission. However, the
equivalence ratio plays an important role in the stability of such flames.
This paper reports the experimental investigation on the flame
characteristics and stability of partially premixed LPG-air flames in
tubular burner. The stability curve obtained for the base case without any
secondary flow shows that the velocity at lift-off, drop-back and blowout
increases with increasing equivalence ratio. In the presence of secondary
co-flow air, the lift-off and blow off velocity decreases compared to base
case indicating poor stability due to extensive flame stretch leading to
aerodynamic quenching. The experimental results show that the velocity of
flow at lift off, blow out and drop back are higher in the presence of
secondary swirl air than the base case. Co-swirl air increases the stability
due to better mixing at the flame base with increased residence time. Flame
stability deteriorates with co-flow air as co-flow strains the flame
boundary due to flame stretch.
Performance analysis of a solar-assisted dual-tank heat pump system for climatic conditions in Turkey
Authors: Yamankaradeniz Nurettin
Published: March 2022

This study aimed to analyze the performance of a solar-assisted dual-tank heat pump system under climatic conditions in Turkey. This system and its components were modeled and simulated using transient system simulation software. The system was designed not only to supply domestic hot water for a restaurant, but also to heat it in winter and cool it in summer. The modeled system works on the principle that a water-to-water heat pump operating between dual tanks transfers the heat from the cold water tank (source side) to the hot water tank (load side). The hot water for both heating and domestic hot water is supplied from the hot water tank throughout all seasons, whereas, the cold water is supplied from the cold water tank for cooling the space in summer. A photovoltaic thermal collector was integrated into the cold water tank to support the source side of the heat pump and also to generate electricity for the system in winter, but was used only for producing electricity in summer. Analyses were carried out for five provinces (Istanbul, Ankara, Izmir, Hakkari, and Trabzon) located in five different regions of Turkey. According to the simulation results, the highest seasonal performance factor (2.65) was obtained for Izmir, whereas the lowest seasonal performance factor value (1.74) was obtained for Hakkari. The system worked 52% more efficiently in Izmir than in Hakkari. With the photovoltaic thermal collector, 17.68% of the total electrical energy consumption of the system was compensated for Izmir Province and 12.09% for Hakkari Province.
The Effect of Endogenous Discretionary Control Choice on Budgetary Slack: An Experimental Examination
Authors: Douthit Jeremy D. , Schwartz Steven T. , Stevens Douglas E. , Young Richard A.
Published: March 2022

This study examines the effect of endogenous control choice on budgetary slack. The superior chooses between two alternatives: no control, wherein the superior commits to accept any budget, and a discretionary rejection authority control, wherein the superior decides ex post whether to accept or reject budgets. For both alternatives, we find that slack is lower when the superior chooses an alternative than when it is assigned exogenously. Our theory and results suggest that a superior's choice of whether to introduce controls signals a superior's expectations and intentions. The superior's choice of no control signals trust and an intention to foster a norm of trustworthiness. The superior's choice of rejection authority signals an above-average willingness to use rejections to enforce norms. Our results suggest that the value of participative budgeting may be increased if superiors can communicate to subordinates the expectations and intentions behind the design of the control system.

This study aims to determine the influencing factors for understanding the intention of the learners in Non-Formal Education to use Blended Learning. In addition, it aims to investigate the relationships of the factors in a theoretical model. This study was conducted due to the lack of research in the world that discusses the adoption of Blended Learning in Non-Formal Education in Developing Countries such as Indonesia. Blended Learning at Non-Formal Education in the Covid-19 era is needed because the education institution has a limited place to accommodate more learners. A questionnaire based on google form was used to collect data. A sample of 566 users of Blended Learning from Non-Formal Education Institutions in Indonesia were used.  All variables from the theoretical model are measured using existing scales.  Structural Equation Model (SEM) was used to analyze the theoretical model.  SPSS and Amos were used as the software tools. This research contributes to the theoretical understanding of Blended Learning adoption as well as practice and provide guidance for Non-Formal Education to successfully implementing Blended Learning in their institutions. From the thirteen initial hypotheses, there are nine significant hypotheses. Three hypotheses with the largest magnitude are SI -> PU, CE -> PEU, and PU -> BI.  SI is the most influencing factor in the adoption of blended learning at non-formal education institutions.

Published: March 2022

This paper aims to identify entrepreneurial modes towards information technology applications in business during pandemic Covid-19 based on Indonesia SMEs’ stories. This study uses phenomenological approach in discerning 33 Economics students’ reports on SMEs’ ways in relating to social media platforms in the midst of the pandemic as relatively different business instruments driven by information technology along with their encounters to new opportunities within novel landscape of business. The reports indicate a general pattern of three critical stages linked to entrepreneurial challenges namely in the first stage business distortion, in the middle efficiency calculation, and finally available resources allocation. Using two factors i.e. learning capability of the business actors and the sophistication degree of information technology applications, the ways through which entrepreneurs relate to information technology within pandemic context can be identified into four types of mode namely adoption, adaptation, aversion, and abandon. Most of them are in adoption mode, few are in adaptation and abandon modes, and none in aversion mode.

ABSTRAK. Kompetensi profesional adalah kemampuan atau keterampilan yang wajib dimiliki oleh seorang guru dalam mengelola proses belajar mengajar. Tujuan penelitian ini adalah untuk mengetahui kompetensi profesional guru PPLK geografi di SMP Negeri Kota Padang. Jenis penelitian yang digunakan adalah penelitian deskriptif dengan pendekatan kualitatif. Informan penelitian adalah mahasiswa PPLK Pendidikan Geografi UNP dan guru pamong mahasiswa PPLK Pendidikan Geografi UNP. Data penelitian diperoleh melalui wawancara dan studi dokumentasi, wawancara dilakukan terhadap guru PPLK dan guru pamong  guna memperoleh data lebih lengkap. Hasil penelitian menunjukkan bahwa Guru PPLK belum sepenuhnya menguasai materi IPS Terpadu secara luas dan mendalam. Pada umumnya guru PPLK bisa menguasai materi geografi tapi pada materi sejarah, ekonomi dan sosiologi belum dikuasai secara mendalam. Dalam mengembangkan materi guru PPLK belum mampu mengembangkan materi pembelajaran secara kreatif. Guru PPLK jarang mengaitkan materi pembelajaran dengan ilmu pengetahuan lain. Dalam pelaksanaan proses pembelajaran sebagian guru PPLK jarang menggunakan media, karena keterbatasan proyektor. Untuk mensiasati hal tersebut, guru memanfaatkan papan tulis sebagai media untuk membuat poin-poin pembelajaran. Dengan demikian dapat dipahami bahwa kurangnya media pembelajaran akan menghambat pencapaian pemahaman materi pembelajaran oleh siswa, dan tentunya akan menimbulkan rasa jenuh pada diri siswa.

Представлены результаты исследования социокультурых, нормативных и педагогических предпосылок перехода к реализации модели смешанного обучения в методике преподавания физической культуры в общеобразовательных организациях. Социокультурные предпосылки определены на основе ретроспективного анализа исследуемой проблемы (технологизация как тренд образа жизни современного общества и человека, реализации физкультурного образования). В авторском понимании смешанное обучение выступает базовым регулятивом современного физкультурного образования и физического воспитания личности, обеспечивающим рациональное сочетание информационно-образовательных ресурсов очного обучения (практика) с элементами дистанционного образования (теория) и самообразования в сфере физического саморазвития и самосовершенствования средствами

осознанной, личностно-значимой, безопасно-ответственной, теоретически-осмысленной физкультурно-оздоровительной деятельности.

Основанием для выявления нормативных предпосылок (правовое регулирование охраны жизни и здоровья обучающихся с использованием вариативного спектра организации физкультурно-оздоровительной работы, физического воспитания) послужили результаты изучения нормативно-правовых документов в области физкультурно-оздоровительной работы и информатизации образования.

Обобщение передового педагогического опыта безопасной реализации офлайн и онлайн средств в практике преподавания физической культуры в общеобразовательных организациях, реализации опроса и проведения SWOT-анализа сильных и слабых сторон, а также возможностей и угроз внедрения смешанного обучения в методику преподавания физической культуры позволили выделить педагогические предпосылки исследуемого процесса (обновление образовательных ресурсов физической культуры на основе инновационных цифровых технологий, развитие вариативных форм совместного образовательного взаимодействия по освоению субъектами образования ценностей физической культуры).

Выявлено возрастание роли смешанного обучения в методике преподавании физической культуры, реализующегося как созидательная интеграция и оптимальное соотношение офлайн реалий практических физкультурных занятий и дополняющих их

онлайн теоретических мероприятий просветительского характера. Обоснована целесообразность реализации соответствующей модели на основе оптимального регламентирования традиционного и дистанционного образования (с целью нивелирования или взаимного компенсирования недостатков каждого из них) и разработки программно-методических средств безопасной трансляции информации и развития физической подготовленности обучающихся, воспитания стабильного интереса к регулярным занятиям физкультурно-спортивной направленности.

Yacon becomes an important plant with strong medical and dietary potential. Therefore, studies on the optimization of yacon micropropagation were undertaken. Reproduction of yacon is conducted by traditional methods with green seedlings or long offsets taken from the underground and aboveground rootstock. The influence of different disinfection methods, various initial explants and growth regulators, their concentrations, and combinations on the efficiency of micropropagation have been analyzed. The most effective disinfection was the use of 70% ethanol and 0.5% Tween 20. The optimal initial explants were apical and lateral buds cultured on Murashige and Skoog (MS) medium with 0.2 mg L–1 kinetin and 1 mg L–1 indole-3-acetic acid. The most intensive shoot regeneration occurred on MS medium with 1 mg L–1 thidiazuron and 1-naphthylacetic acid. Histological observations demonstrated the strong effect of growth substances on shoot organogenesis from callus tissue. Shoots obtained from in vitro cultures rooted easily on modified MS media with ½ or ¼ concentration of macroelements, 20 g L–1 sucrose and 3 mg L–1 1-naphthylacetic acid. All plants adapted to ex vitro conditions.
Haemophilia A management with emicizumab: A survey of haematologists in the United States
Authors: Patel Anisha M. , Owens Wendy E. , Poulos Kathleen , Raimundo Karina , Wong Gabriel , Bernard Janet , Powers Janet , Ko Richard H.
Published: March 2022

Background

Emicizumab is a bispecific monoclonal antibody approved in the United States (US) for the treatment of people with haemophilia A (PwHA) with or without factor VIII (FVIII) inhibitors. Changes to haematologists’ practices since the approval of emicizumab are of interest to the haemophilia A community.

Aim

To identify the clinical characteristics of PwHA receiving emicizumab (PwHArE) in the real-world setting and gain insight into the disease management practices of haematologists treating PwHArE.

Methods

In total, 50 haematologists across the US completed a one-time, 30-minute, online, qualitative survey consisting of 55 questions (including 11 screening questions) in May 2019. Haematologists were required to be board-certified in haematology, practising in the US, ≥2 years post-residency experience, and currently treating ≥3 PwHA with emicizumab.

Results

Haematologists reported their PwHArE were mostly adults (aged ≥18 years; 66%) with severe phenotypes (66%), with and without FVIII inhibitors. Haematologists perceived that PwHArE had similar or better treatment adherence (40% and 50%, respectively) compared with PwHA on other treatments, sought the same or lower levels of routine care (72% and 14%, respectively), and were similarly or more physically active (52% and 32%, respectively). Additionally, most haematologists currently using immune tolerance induction (ITI) in PwHArE reported using lower doses of FVIII (73%) and shorter durations (45%) for ITI.

Conclusions

Availability of emicizumab has resulted in changes in the care of PwHArE, including bleed management, FVIII monitoring, activity guidance, surgery, and use of ITI. Understanding patterns of disease management can inform clinical care.
Design Thinking and Bricolage for Frugal Innovations during Crisis
Authors: Mishra Oly
Published: March 2022

The rapid spread of COVID-19has created resource-constraints. This study focuses on the application of design thinking in frugal innovations by social entrepreneurs to face the challenges during the COVID-19 pandemic. It discusses the case of an Indian social entrepreneur who essentially provides solutions for menstrual health and hygiene to unprivileged and rural women in India. When faced with the COVID-19 pandemic, the social entrepreneur re-purposed the manufacturing process and implemented bricolage to produce masks which were the need of the hour. The manufacture of masks was a frugal innovation due to the resource constraints during the pandemic. The research paper is qualitative, and it follows an inductive case study approach. The implementation of design thinking in frugally innovating is established through the content analysis of the interviews of the social entrepreneur and her team members. It presents practical implications of design-thinking for frugal innovations by social entrepreneurs in adversity.
