Authors: Demir İbrahim , Özden Eren , Gökdaş Zeynep , Njie Ebrima S. , Aydin Mine
Published: December 2020

Aims: To test radicle emergence count in order to predict normal germination percentages of onion lots.Methods and Results: This work was conducted to test the potential for 2 mm radicle emergence (RE) to predict normal seed germination percentages of 20 onion seed lots. In the first stages of the study RE counts at 72, 76 and 80 h were highly predictive (p<0.001, R2=0.94-0.95) of normal germination after 12 days. In the second stage, the regression formula (y=45.9+0.52x) developed for the 80th hour radicle emergence to predict normal germination of 20 seed lots at various aging levels collected from the market. RE counts (%) of the 20 lots at 80 h were used to predicted values by using the formula. Actual normal percentages of 20 lots were determined after 12 days of germination testing. Then regression analysis was performed on both values. Results showed that predicted and actual normal germination percentages were highly related to actual normal germination percentages (R2=0.95, p<0.001). Means of the predicted (79.6%) and actual (80.4%) values were very similar. Results indicated that RE testing has a potential to estimate normal germination percentages of onion seed lots. Conclusions: RE count at 80h was highly related to normal germination percentages after 12 days (p<0.001, R2=0.95) in commercial onion seed lots.Significance and Impact of the Study: RE testing can be used in the prediction of normal germination percentages of any commercial onion seed lots within a short period, rather than waiting until the final count (12 days) in onion germination tests.
Farklı azot dozlarının kişniş (Coriandrum sativum L.) yaş herba uçucu yağ bileşenleri üzerine etkisi

Published: December 2020

Amaç: Bu çalışma, Lolium perenne çeşitlerinin fide gelişim aşamalarında tuz ve kuraklık stresine tepkisini belirlemek amacıyla yapılmıştır.Yöntem ve Bulgular: Tohum materyali olarak dört çok yıllık çim çeşidi (Apple GL, Ecologic, Barminton ve Solstice II) kullanılmıştır. Lolium perenne çeşitlerinde fide gelişim aşamalarında tuz (0, 50, 100, 150 ve 200 mM NaCl) ve kuraklık (0, -0.4, -0.8, -1.2. ve -1.6 MPa, PEG-6000) stresi oluşturmak için beş farklı dozda sodyum klorür ve polietilen glikol kullanılmıştır. Fide gelişimi denemeleri tesadüf parselleri deneme deseninde faktöriyel düzende 4 tekrarlamalı olarak yürütülmüştür. Lolium Perenne çeşitlerinin fide gelişimi, tuz ve kuraklık stresine toleransları araştırılmıştır. Araştırma sonucunda tuz uygulamasında fide kök uzunluğu hariç tüm özelliklerde çeşit, tuz stresi ve çeşit x tuz stresi interaksiyonların önemli olduğu belirlenmiştir. Kuraklık uygulamasında fide kök uzunluğu ve fide sap uzunluğu hariç tüm özelliklerde çeşit x PEG interaksiyonların önemli olduğu belirlenmiştir. Genellikle tuz ve kuraklık stresi arttıkça incelenen özelliklerde önemli azalma olduğu ortaya konmuştur.Genel Yorum: Lolium perenne çeşitlerinin fide gelişimi incelenen özelliklere göre, farklı oranda tepkiler vermiştir. Tuz’un ve PEG-6000'in Lolium perenne fide gelişiminde kuraklık stresi yaratmada yararlı bir ajan olduğu sonucuna varılabilir, ancak Lolium perenne tuz ve kuraklık stres toleransını daha iyi belirlemek için (150 mM )tuz ve (-1.2 MPa)'dan daha düşük ozmotik potansiyeller uygulanmalıdır. Çalışmanın Önemi ve Etkisi: Küresel ısınmanın etkilerini giderek hissedildiği günümüzde kuraklık sorunu ve alternatif su kaynaklarının kullanımına toleranslı tür ve çeşitlerin belirlenmesi çok önemli olacaktır. Kuraklık ve tuzluluk problemine toleranslı tür ve çeşitlerin kısa dönemde belirlenmesi de ayrıca önem taşımaktadır. 21 gün gibi kısa bir çalışma süreci ile yeşil alanlarda kullanılabilecek çeşitlerin test edilmesi tuzluluğa veya kurağa dayanıklı ya da toleranslı çeşidin belirlenmesi çim alanların sürdürülebilirliği açısından önem arz etmektedir.

Published: December 2020

Aims: In this study, the best sampling time and tissues for phytoplasma detection in twenty pear trees (cv. Deveci) infected by ‘Candidatus Phytoplasma pyri’, causal agent of pear decline disease, in Bursa province of Turkey were investigated.Methods and Results: Sampling was done throughout the year in leaf midribs, shoot and root tissues, where as the flower tissues were tested once a year in March and fruit tissues in September. All samples were analyzed by nested-PCR using P1/P7 and fU5/rU3 universal primer pairs. Nested PCR products were digested with RsaI and SspI restriction enzymes. The results revealed that the detection rate of ‘Ca. P. pyri’ in different plant tissues was greatly depending on the sample collection period. The fruit tissues, which were only sampled in September due to the ripening time of Deveci pear cultivar in Bursa, showed the highest detection rate of ‘Ca. P. pyri’ (100%) followed by flower tissues (75%). The average detection rate in root, shoot tissues and leaf midribs was found as 43.75, 39.58 and 16.25%, respectively. The present results showed that the best plant tissues for detecting ‘Ca. P. pyri’ in pear trees were fruit columella and flowers. The highest detection rate of this phytoplasma in root tissues was found from November to March, whereas it could be detected whole year around except summer months in shoot samples in Turkey.Conclusions: For 'Candidatus Phytoplasma pyri', detection, if there is no seasonal limitation for testing, the most suitable tissues are fruits and flowers. When it comes to testing throughout the year, the most suitable tissues were determined as the root, the phloem and cambium layer of the shoots and the leaves, respectively.Significance and Impact of the Study: This study on seasonal variations of ‘Candidatus Phytoplasma pyri’ in different pear tissues has been first time investigated in Turkey. This preliminary data provides important knowledge on molecular detection of Ca. P. pyri, causal agent of pear decline disease for further studies and sertification-quarantine programmes of pear trees in Turkey.
Farklı dozlarda tuz ve mikoriza uygulamalarının biberde hormon, antioksidan, fenolik ve organik asit içeriklerine etkisi
Authors: Çimrin Kerim Mesut , Başak Hakan , Turan Metin
Published: December 2020

Amaç: Çalışmada, mikoriza (ROOTS-novozymes endo-mycorrhiza (VAM) fungus (Glomus spp.)) ve artan tuz dozlarının biber bitkisinin (Capsicum annuum L.) kök ve gövde dokularının; hormon, toplam fenolik ve organik asit içerikleri ile toplam antioksidan kapasitesi üzerine etkisini belirlemek amaçlanmıştır. Yöntem ve Bulgular: Serada tesadüf blokları deneme deseninde göre yürütülen çalışmada, toprak doldurulmuş saksılardaki biber bitkilerine dört farklı dozda tuz (T0: 0, T50: 50, T100: 100 ve T150: 150 mM NaCl) ile mikorizalı ve mikorizasız olmak üzere mikorizanın iki dozu (M0: 0, M100: 100 adet spor/bitki) uygulanmıştır. Çalışmada, kök ve gövde dokularında giberilik asit (GA), salisilik asit (SA) ve indol asetik asit (IAA) düzeyleri artan tuz dozlarının etkisiyle istatistiksel olarak önemli düzeyde azalmıştır. Biber bitkisi absisik asit (ABA) içeriği mikoriza uygulanmamış bitkilerin kök ve gövde dokularında tuz dozlarındaki artış ile önemli düzeyde artmışken, mikoriza uygulanan bitkilerde tuz dozlarındaki artış ABA içerini etkilememiştir. Sadece 50 mM tuz dozunda belirlenen ABA içeriği mikoriza uygulanmışlarda mikorizasızlara göre önemli düzeyde daha yüksek belirlenmiştir. Toplam fenolik içeriği ve antioksidan kapasitesi tuz stresinin etkisiyle kök ve gövde dokularında önemli düzeyde azalmışken, 50 mM NaCl uygulanmış mikorizalı bitkilerde en yüksek değerde belirlenmiştir. Organik asit içerikleri, gövde tartarik ve maleik asit ile kök maleik asit hariç, uygulanan tuz dozlarındaki artış ile kök ve gövde dokularında kontrol bitkilerine göre artmıştır. Mikoriza uygulanmış bitkilerin gövde bütirik, malonik ve malik asit içerikleri mikoriza uygulanmamışlar daha yüksek belirlenmişken, kök dokularında ise malonik ve malik asit içerikleri mikorizalı olanlarda daha yüksek belirlenmiştir. Genel Yorum: Mikorizanın özellikle 50 mM tuz dozunda gövde ve kök dokularında toplam fenolik ve antioksidan içeriklerinin yanı sıra ABA düzeyini arttırmasından dolayı strese karşı tolerans göstermede etkili olduğu, ancak daha yüksek tuz konsantrasyonlarında bu olumlu etkisinin bozulduğu belirlenmiştir. Çalışmanın Önemi ve Etkisi: Sonuç olarak, mikorizanın ılımlı tuz stresinde bitki toleransını arttırdığı ancak, yüksek ve çok yüksek tuz tuz streslerinde etkisiz kaldığı söylenebilir.

Air pollution throughout the world, in general, has been at a very alarming rate with the increase in industrial and human activities. In Indonesia, the level of air pollution caused by various industries, especially from motor vehicles, is no longer a secret. Particularly, in the province of Aceh, air, water, and air noise quality in recent years have resulted in deteriorating health for humans and living things. This research analyzed air quality, water odor, and air noise level in the Aceh Province. The results for air quality analysis show an increase in emissions. The noise level of the three regions analyzed is still below the thresholds set. Meanwhile, the results of water odor analysis show its level has exceeded the thresholds set by the Ministry of Environment. Therefore, industrial activities can have an impact on the environment when they are not managed appropriately.
Tetramesa amica and its parasitoid Eurytoma amicophaga (Hymenoptera, Eurytomidae): two new species associated with medusahead, Taeniatherum caput-medusae (Poaceae)
Authors: Lotfalizadeh Hossein , Rasplus Jean-Yves , Cristofaro Massimo , Marini Francesca
Published: December 2020

Medusahead, Taeniatherum caput-medusae (Poales: Poaceae), is an annual grass native to central Asia and the Mediterranean region. It is a noxious, invasive weed in much of western North America. During field explorations carried out in Greece in 2017, the new phytophagous eurytomid Tetramesa amica Lotfalizadeh, sp. nov. and its parasitoid Eurytoma amicophaga Lotfalizadeh, sp. nov., also new to science, were recorded for the first time on medusahead. These new species are described and characters that enable to recognize them from their closest relatives are summarized. Tetramesa species are generally species-specific gall-inducers. They induce damages that may have a significant impact on the physiology of infested plants by reducing the productivity of flowering heads and seed weight. Based on these data, T. amica Lotfalizadeh, sp. nov. is currently being investigated as a candidate biological control agent of medusahead.
Phénoménologie du jugement judiciaire
Authors: Mazabraud Bertrand
Published: December 2020

L'expression « jugement judiciaire » désigne autant la manière de juger que la décision rendue. Or l'attention est généralement focalisée sur le « jugement rendu » - au point d'en faire un « produit » servant des objectifs politiques et sociaux, tandis que le comment du jugement reste plus énigmatique, oscillant entre un jugement de connaissance (jusqu'à la limite d'un jugement scientifique) et un jugement esthétique (à la limite de l'artistique). Il convient donc, en suivant Kant et Ricœur, d'esquisser une phénoménologie du jugement judiciaire, de s'attarder sur ses modalités, pour mieux appréhender son « rendu ». Ce moment se découvre comme une dialectique ouverte d'interprétation et d'argumentation, qui fait pendant à la clôture de la décision. À l'oublier, c'est l'équilibre bien pesé du jugement qui se trouverait rompu.
L'impartialité au cœur de l'autorité du juge. Approches philosophiques
Authors: Allard Julie
Published: December 2020

L'autorité du juge est souvent menacée par la subjectivité des décisions rendues, auquel on oppose un impératif d'impartialité. Du point de vue philosophique, l'impartialité, liée à la position tierce du juge, est perçue comme sa capacité à mettre entre parenthèse sa subjectivité, ses opinions et convictions personnelles, ses sentiments et ses affects, qui pourraient influencer de manière arbitraire sa décision. Cette impartialité est conçue par la tradition rationaliste comme une distance avec le corps et ses fragilités : il s'agit de juger en pur esprit (Platon) ou en être inanimé (Montesquieu). Deux traditions contestent cette conception de l'impartialité : selon les empiristes, aucun jugement n'est possible en surplomb, sans affect ni émotion (Hume) ; selon les sceptiques, la prétendue impartialité du juge est un rideau de fumée qui cache le pouvoir des juges et surtout, l'arbitraire de leurs décisions (Montaigne). Les penseurs contemporains comme Hannah Arendt tentent de concilier l'impératif de rationalité et le recours aux sentiments et à l'imagination pour bien juger, et aboutissent ainsi à une notion d'impartialité qui n'est pas ontologique, mais conçue comme un retour critique sur soi.
Le doute et le magistrat. Réflexions historiques sur la quête impossible d'une preuve infaillible
Authors: de Carbonnières Louis
Published: December 2020

Pour le magistrat, le doute est à la fois une méthode et un outil. Tout au long de l'histoire juridique, le juge a envisagé ce doute d'une manière a priori paradoxale, voire illogique pour qui n'est pas familier des cours de justice. Il s'agit de douter pour ne plus douter, pour créer une sûreté juridique. Le doute en apparaît comme un moyen qui se dissout dans un résultat qui en est l'antinomie. Mais cela a conduit le juge occidental à rechercher une preuve infaillible, qui lui ôte tout doute, au point que le magistrat adopte une attitude mentale similaire face à la preuve, qu'il s'agisse du jugement de Dieu ou du jugement par l'ADN et abdique par humilité son rôle d'appréciation. Face à l'essor de la preuve scientifique, il devra décider s'il veut se réduire au rôle de bouche juridique d'un expert scientifique, étranger au monde du droit.
Le pouvoir des sujets dans les institutions : de sa négation à sa reconnaissance
Authors: Monceau Gilles , Fortuna Cinira Magali
Published: December 2020

Depuis les années 1960, la manière dont les institutionnalistes ont abordé le rapport au pouvoir et les rapports de pouvoir a évolué. Les événements de mai 1968 ont interféré avec les théorisations et expérimentations de Georges Lapassade et de René Lourau. L’intervention socianalytique (Lapassade et Lourau, 1971) a ainsi été pensée comme un dispositif visant à dévoiler le pouvoir de l’institué étatique sur les rapports sociaux. Cependant, les analystes institutionnels ont aussi cherché à élaborer des alternatives à l’institué étatique. La démarche socioclinique institutionnelle (Monceau, 2003), dans l’éducation permanente en santé au Brésil (Fortuna et coll., 2019) et dans l’analyse des pratiques professionnelles d’éducation en France (Monceau, 2012), accompagne des collectifs dans la reconnaissance et le travail de leur propre pouvoir individuel et collectif.
« Faire institution » en contexte de réorganisations à répétition dans la protection de l’enfance
Authors: Pétry Philippe
Published: December 2020

Cet article décrit les profondes transformations organisationnelles qui ont marqué le secteur de la protection de l’enfance depuis les années 2000. Il tente de décrire les effets sur les pratiques professionnelles des équipes éducatives et de l’encadrement. Il part de pratiques d’intervention en formation en analyse des pratiques et en régulation dans une multiplicité d’institutions. Il mobilise les notions de sociologie des organisations et de psychologie sociale clinique pour tenter d’en analyser les divers effets imaginaires. La notion de constance du cadre (Bleger) ainsi que l’importance du holding institutionnel collectif (Delion) permettent de comprendre les dimensions archaïques de l’imaginaire individuel et groupal qui sont à la base du travail institutionnel. Cet article se termine par une réflexion critique sur la notion de désinstitutionnalisation et sur les conditions de mise en place des analyses de pratiques dans un tel contexte.

Published: December 2020

 This work is mainly based on the prototyping of a disciplinary information space for a new LMS. Our work is first to think about the conditions for creating a real LMS between learners and teachers. We have chosen to base ourselves on the hybridization between four learning theories as the basis for teaching this LMS, namely traditional pedagogy, behaviorism, cognitivism and social constructivism. These pedagogies have already proven themselves, mainly in classroom learning situations. The LMS consists of different activity spaces for teaching and learning activities. We limit ourselves in this work to the prototyping of disciplinary information space for a new LMS based on IMS-LD, NoSQL MongoDB database, and Symfony framework.

OPTIMIZATION-DRIVEN DEEP RECURRENT NEURAL NETWORK FOR INTRUSION DETECTION AND HEALTH RISK ASSESSMENT IN WIRELESS BODY SENSOR NETWORK
Authors: Alameen Abdalla , Gupta Ashu
Published: December 2020

Wireless body sensor network (WBSN) has gained great attention in the environmental and military applications, but security is the major issue, nowadays. In addition, the data exchanged through the wireless sensor network (WSN) is vulnerable to several malicious attacks because of the physical defense equipment needs. Hence, various intrusion detection methods are required for defending against such attacks. Accordingly, an effective method, named deep recurrent neural network (Deep RNN), is proposed in this research for detecting the intrusion in WBSN. At first, the WBSN nodes are utilized to sense the data from the health records of patient for acquiring certain parameters to make risk assessment. Then, WBSN nodes transmit the data to the target nodes using the obtained parameters. After the determination of parameters, the WBSN nodes are responsible to collect the information of the patient and transfer the obtained information to cluster heads (CHs) based on the hybrid harmony search algorithm–particle swarm optimization (HSA–PSO). HSA–PSO is utilized for identifying the optimal CH node iteratively. From the selected CHs, secure communication is done to exchange the data packets. After that, the KDD features are extracted and intrusion detection is done using the proposed Deep RNN. After the genuine users are detected, the classification is done using fractional cat-based salp swarm algorithm (FCSSA) for the risk assessment. The performance of the intrusion detection and health risk assessment in WBSN based on the proposed model is evaluated based on accuracy, sensitivity, and the specificity. The developed model achieves the maximal accuracy of 95.79%, maximal sensitivity of 95.97%, and the maximal specificity of 95.61% using Cleveland dataset.
Effect of General Endotracheal Anesthesia and Mechanical Ventilation on the Echocardiographic Measurements in Severe Aortic Stenosis
Authors: Kanchi Muralidhar , Manjunath Rudresh , Natarajan Pooja , Belani Kumar
Published: December 2020

Introduction:

We measured the peak pressure gradient (pPG) and mean pressure gradient (mPG) obtained by transesophageal echocardiography (TEE) after induction of anesthesia and compared it with the preoperative pPG and mPG by transthoracic echocardiography (TTE) in adults with aortic stenosis (AS). We also compared the aortic valve area (AVA) measurements as obtained preoperatively by TTE versus those by TEE following induction of general endotracheal anesthesia (GETA) during the inspiratory phase, expiratory phase of the ventilatory cycle and with incremental increases in tidal volume.

Materials and Methods:

All patients had preoperative TTE within 1 month of surgery and was reviewed 1 day before the surgery. After anesthetic induction, precardiopulmonary bypass (CPB) TEE evaluation was done to measure mPG and pPG across AV, under steady-state conditions. Three different controlled tidal volumes: 8 ml, 10 ml, and 12 ml per kg body weight were utilized during the TEE measurements.

Results:

A total of 90 adults underwent aortic valve replacement from 2017 to 2018. The preoperative pPG and mPG across the AV by TTE was 96.7 ± 23.27 mmHg and 60.7 ± 18.1 mmHg, respectively. Compared to preoperative TTE, pre-CPB TEE pressure gradient during both phases of ventilation under GETA was significantly lower. The pPG and mPG were higher during inspiration as compared to those in the expiratory cycle during mechanical ventilation under GETA (pPG during inspiration = 66.63 ± 22.15 mmHg; mPG during inspiration = 38.24 ± 13.65 mmHg; pPG during expiration = 52.49 ± 19.10 mmHg; mPG during expiration = 30.76 ± 12.66 mmHg). There were no significant changes in AVA between TTE/TEE and inspiration/expiration.

Conclusions:

The findings of this study demonstrate that the TEE pre-CPB PGs underestimated the severity of AS; hence, the severity of AS must be interpreted with caution during GETA and mechanical ventilation (MV). In addition, PGs must be done at similar points in the respiratory cycle.
Left Atrial Remodeling in Disease: Association with Clinical Markers
Authors: Piedade Joel Quadros , Adhyapak Srilakshmi M. , Muralidharan Pradyumna , Raj John Michel , Fantini Fabio , Varghese Kiron
Published: December 2020

Background:

The role of left atrial (LA) enlargement has a significant and independent association with moderate and severe diastolic dysfunction, atrial fibrillation, and left ventricular (LV) end-diastolic volume. Clinical features of heart failure have shown a correlation with LV dilatation and LV ejection fraction (LV).

Aims:

Correlation of clinical features with substrates of cardiac remodeling, especially left atrial (LA) remodeling, has not been well-documented. We sought to determine the major clinical factors that are associated with LA enlargement in subjects with heart failure.

Materials and Methods:

We studied 200 patients who presented with breathlessness due to underlying cardiac disease. The association of clinical features of cardiac disease with LA remodeling was studied using three-dimensional echocardiography.

Results:

This was a cross-sectional study conducted between January 2016 and January 2017. We found that clinical features of heart failure such as breathlessness, elevated jugular venous pressure, dilated LV, diastolic dysfunction, severe mitral regurgitation, pulmonary hypertension, and abnormal tricuspid annular plane systolic excursion were significantly associated with LA enlargement. LA volume was significantly and independently associated with moderate and severe diastolic dysfunction, atrial fibrillation, lower hemoglobin levels, and LV diastolic size on echocardiography. The sensitivity and specificity of breathlessness with LA enlargement were not significant.

Conclusions:

Clinical features of heart failure, namely breathlessness, were significantly associated with LA enlargement. LA enlargement was not a sensitive or specific marker of breathlessness in heart failure.

Complete transposition of great arteries (TGA) is a common and nearly fatal cyanotic congenital cardiac malformation if not treated in time. Without any intervention, nearly 50% succumb in neonatal period and 90% before their first birthday. Advancements in diagnostic and surgical modalities have led to significant improvement in the survival rate of these children. This article discusses comprehensive echocardiographic evaluation in TGA and its variants before and after surgical correction.
Swallowing-induced supraventricular arrhythmia
Authors: Ozturk S , Yetkin E
Published: December 2020

Atypical presentations of supraventricular arrhythmias constitute a diagnostic challenge which are not frequently reported in literature. Swallowing-induced supraventricular arrhythmia (SI-SVA), which was first described in 1926, is an intriguing presentation of supraventricular tachycardia and occurs during a wet or solid swallow. A 67-year-old man presented to our outpatient clinic complaining from recurrent episodes of sensation of palpitations and short duration pressure on his chest while swallowing since the last 2 weeks. Ambulatory rhythm Holter monitoring was suggestive of atrial fibrillation (AF) or atrial tachycardia attacks during swallowing. In addition, electrocardiography performed during solid food swallowing, showed short duration of AF consistent with the patient's symptoms. The patient was successfully treated with amiodarone. The main cause of SI-SVA is not known. Cross-talk of nerves during the impulse propagation might be the underlying cause of this phenomenon.
Nonlinear centralizers in homology II. The Schatten classes
Authors: Cabello Sánchez Félix
Published: December 2020

An extension of

X

by

Y

is a short exact sequence of quasi Banach modules and homomorphisms

0\longrightarrow Y\longrightarrow Z\longrightarrow X\longrightarrow 0

. When properly organized all these extensions constitute a linear space denoted by

\mathrm {Ext}_B(X,Y)

, where

B

is the underlying (Banach) algebra. In this paper we "compute" the spaces of extensions for the Schatten classes when they are regarded in its natural (left) module structure over

B=B(\mathscr H)

, the algebra of all operators on the ground Hilbert space. Our main results can be summarized as follows:

\mathrm {Ext}_B(S^p,S^q) = \begin{cases} 0 &\text{if $0 < q < p\leq\infty$ or $p=q=\infty$}, \\ \mathrm {Ext}_{\mathbb{C}}(S^1,\mathbb{C}) &\text{if $q=p$ is finite}, \\ \mathrm {Ext}_{\mathbb{C}}(\mathscr H) &\text{if $0 < p < q\leq\infty$}. \end{cases}

In the first case, every extension

0\longrightarrow S^q\longrightarrow Z\longrightarrow S^p\longrightarrow 0

splits and so

X=S^q\oplus S^p

. In the second case, every self-extension of

S^p

arises (and gives rise) to a minimal extension of

S^1

in the quasi Banach category, that is, a short exact sequence

0\longrightarrow \mathbb{C} \longrightarrow M \longrightarrow S^1\longrightarrow 0

. In the third case, each extension corresponds to a "twisted Hilbert space", that is, a short exact sequence

0\longrightarrow \mathscr H \longrightarrow T\longrightarrow \mathscr H\longrightarrow 0

. Thus, the subject of the paper is closely connected to the early "three-space" problems studied (and solved) in the seventies by Enflo, Lindenstrauss, Pisier, Kalton, Peck, Ribe, Roberts, and others.

Examining Humanity in Bernard Beckett’s Genesis: Anaximander, Plato, Classical Philosophy and Gothic in Dystopian Fiction for Young Adults
Authors: Hale Elizabeth
Published: December 2020

New Zealand author Bernard Beckett’s young adult novel Genesis (2006) blends classical philosophy and Gothic tropes in a dystopian novel about the nature and ends of humanity. It is a curious work, presented in the form of philosophical dialogue and set in a future world known as The Republic, in which robots have triumphed over humanity and formed a new society based on rational order. Yet sinister underpinnings to their society and their emotional origin-story, which forms the core of this novel, show both that their rational world order is built on lies, deception, and murder, and that the human soul is harder to be rid of than they imagine. The clash between robots and humans is depicted as a clash between reason and passion, and also as a clash between a classical calm (seen in the Republic’s emphasis on classical philosophy) and the Gothic emotions associated with the dark, but emotional, side of humanity. Genesis is a compelling reflection on the nature of the human soul, aimed at young readers. This paper will trace how that reflection plays out through Beckett’s use of classical and Gothic ideals in an unusually thought-provoking dystopian work for young readers.

Authors: Kasochi Chimwasu , Julius Peter , Mweemba Isaac , Kayamba Violet
Published: December 2020

Background: There are scanty data on the occurrence of gastric tumours overexpressing human epidermal growth factor receptor 2 (HER2) in Africa.

Objective: To assess HER2 protein overexpression in gastric and gastroesophageal junction adenocarcinoma (GGEAC) samples from a single centre in Zambia.

Methodology: This was a cross-sectional study of formalin-fixed paraffin-embedded blocks with GGEAC. Prepared slides were first stained with Haematoxylin and Eosin and then evaluated for HER2 protein overexpression by immunohistochem- istry.

Results: A total of 57 gastric tissues were stained and evaluated for HER2 overexpression. Thirteen (23%) showed overex- pression, 41/57 (72%) had negative and 3/57 (5%) had equivocal staining. The equivocal cases were excluded from the final analysis. Of the remaining 54 tissues, 28 (52%) were from females, and 26 (48%) were from males. The mean age was 59 years (SD 15 years). HER2 overexpression was highest in moderately differentiated tumours (p=0.0005). Intestinal type tu- mours had a higher occurrenc of HER2 overexpression than diffuse or mixed sub-types (p=0.0087). HER2 overexpression was not associated with age (p=0.27), sex (p=1.00) or anatomical location (p=1.00).

Conclusion: The occurrence of GGEAC HER2 overexpression in Zambian patients is similar to proportions reported elsewhere, and it is associated with moderately differentiated tumours of the intestinal type.

Knowledge and barriers on correct use of modified guidelines for active management of third stage of labour: a cross sectional survey of nurse-midwives at three referral hospitals in Dar es Salaam, Tanzania
Authors: B Ramadhani Fatina , Liu Yilan , Menrad Lembuka Melania
Published: December 2020

Background: Despite the fact that it is possibly preventable, postpartum haemorrhage (PPH) is the global most deadly form of obstetric bleeding, mainly sub-Saharan Africa with at least one-fourth of maternal deaths in East African regions. Active management of third stage of labour (AMTSL) is recommended to prevent PPH. However, AMTSL guidelines have been revised since 2006.

Objectives: To examine the current status of nurse-midwives’ knowledge on modified AMTSL guidelines and highlight barriers to AMTSL correct use.

Method: Descriptive cross sectional survey was conducted to 160 nurse-midwives at three referral hospitals in Dar es Sa- laam, Tanzania. One-way, interactive modes ANOVA and Chi square (χ2) test were run in SPSS 21 version to compare the association of independent and dependent variables.

Results: Virtually all nurse-midwives knew the first recommended uterotonic (99.4%) and delayed cord clamping (98.8%) protocols as modified. Knowledge was significantly contributed by multiple factors; p=0.001. Reported correct AMTSL use was 46.8% which was significantly affected by AMTSL training (χ2 = 6.732, p = 0.009) and prioritizing atteding an asphyx- iated baby (χ2 = 5.647, p = 0.017).

Conclusion: Regardless of high nurse-midwives’ AMTSL knowledge; it is imperative that responsible authorities plan ap- propriate strategies to solve reported barriers affecting correct AMTSL use.

Autonomía y formación a nivel posgrado. Una reflexión sobre las tensiones del proceso formativo desde La reproducción / Autonomy and training at the postgraduate level. A reflection on the tensions of the training process from Reproduction
Authors: Cerón Martínez Armando Ulises
Published: December 2020

¿Es la autonomía intelectual de un estudiante en formación producto de su proceso formativo a nivel posgrado? ¿En qué medida la autoridad pedagógica de un director de tesis ahoga o motiva autonomía intelectual de su tutorado para que con autoridad pueda este auto-representarse en obras y productos académicos? ¿Cómo conciliar las metas de las instituciones educativas a nivel posgrado de formar para la investigación y a la vez pretender desarrollar la autonomía intelectual del estudiante al que se le pretende formar como investigador educativo? Con base en experiencias previas en la Maestría y el Doctorado en Ciencias de la Educación de la Universidad Autónoma del Estado de Hidalgo, se comparten algunas consideraciones respecto al tema sugerido, y analizadas desde la obra de Bourdieu y Passeron La reproducción, en donde se logra identificar al menos cuatro tipos o dimensiones de autoridad en los actos pedagógicos, que permiten comprender el grado de autonomía intelectual alcanzable por el estudiante de posgrado por el tipo de lecturas y producciones académicas que realiza, no necesariamente durante su proceso formativo, sino una vez acabado éste, pues así podría hablarse de un habitus investigativo “bien formado”.

ABSTRACT
Is the intellectual autonomy of a student in training a product of his training process at the postgraduate level? To what extent does the pedagogical authority of a thesis supervisor stifle or motivate the intellectual autonomy of his student so that can be self-authorized in academic works and products? How to reconcile the goals of educational institutions at the graduate level of training for research and at the same time trying to develop the intellectual autonomy of the student who is intended to be trained as an educational researcher? Based on previous experiences in the Master’s and Doctorate in Educational Sciences of the Autonomous University of the State of Hidalgo, some considerations regarding the suggested topic are shared, and analyzed from the work of Bourdieu and Passeron Reproduction, where manages to identify at least four types or dimensions of authority in pedagogical acts, which allow understanding the degree of intellectual autonomy achievable by the graduate student by the type of readings and academic productions he performs, not necessarily during his training process, but once finished this one, because thus one could speak of a “well-formed” investigative habitus.

Aromatherapy is a therapy that utilizes steam from the essential oils of certain plants. Essential oils are oils produced from plant parts, such as roots, bark, stems, flowers, leaves, and seeds that have volatile properties at room temperature without undergoing decomposition by means of distillation. This study aims to determine the effect of a comparison of the concentration level of essential oils on physical properties and consumer preferences and to find out the aromatherapy massage oil formulation that produces the best massage oil. This study uses a completely randomized design (CRD) with 1 factor, namely the difference in the ratio of the essential oil of the nightly flower to the essential oil of lime. The experiment was carried out 2 times. The usual dilution was 1 ml of essential oil in 50 ml of carrier oil. The treatments are P1 (0.2 ml of nightly essential oil: 0.8 ml of lime essential oil), P2 (0.4 ml of nightly essential oil: 0.6 ml of lime essential oil), P3 (0.5 ml nightly essential oils: 0.5 ml lime essential oil, P4 (0.6 ml nightly essential oils: 0.4 ml lime essential oil), and P5 (0.8 ml nightly essential oils), 2 ml of lime essential oil). The parameters observed were pH, specific gravity, viscosity, refractive index, color, and hedonic test.

Generally only used the leaves of tobacco plants as raw material for cigarette and stems discarded as waste. The use of waste tobacco rod has the potential to be converted into primary packaging such as trays range chicken eggs because it has a high cellulose content. Tobacco rod contains a relatively high amount of cellulose, reaching 56.10 percent of dried tobacco stalks. The process is done in making pulp fiber or tobacco stem malalui process of alkali (NaOH) with specific concentration to produce pulp that is good. The use of NaOH aims to degrade lignin by means of partial overhaul of bond. The existence of lignin in the pulp generally unfavorable effect on the quality of pulp for fiber becomes rigid, Statistical data analysis using ANOVA If treatment showed differences do a further test using Duncan's Multiple Range Test (DMRT) at significance level of 5 percent.

EFFECT OF DIFFERENT TYPES OF RICE HUSK ASH ON SOME GEOTECHNICAL PROPERTIES OF CEMENT-ADMIXED SOIL
Authors: Nguyen Duong
Published: December 2020

Rice husk ash (RHA) is an agricultural residue and has shown great potential for soil stabilization. However, the research on the utilization of RHA for soft soil improvement using cement deep mixing method is still limited and the efficiency of using different RHA types for soil improvement needs to be clarified. In this study, the effect of different RHA types on Atterberg limits, unconfined compressive strength (UCS), and elastic modulus (E50) of soil-cement mixtures will be investigated. Two types of RHA which obtained from open fire burning (RHA1) and burning in a furnace under controlled conditions of temperature and duration of burning (RHA2), were used for this study. The RHA contents from 0 to 15% and 10% cement of the dry weight of the soil were used to treat the soft soil. The research results show that the types of RHA insignificantly affect the change in Atterberg limits of cement-admixed soil. Regarding the soil strength, the RHA2 shows a higher efficiency in the enhancement of treated soil strength at 28 days of curing than the RHA1. The addition of 12% RHA2 to the cement-admixed soil can increase the UCS and E50 values of treated soil by more than 50%.
ROCK JOINTS ANALYSIS TO DETERMINE THE MAIN STRESS FIELD IN BUSTANAH STRUCTURE NORTHEAST OF IRAQ
Authors: Shakir Madeha
Published: December 2020

Joints are among the most widespread geologic structures as they are found in most each exposure of rock. They differ greatly in appearance, dimensions, and arrangement, besides they occur in quite different tectonic environments. This study is important because joints provide evidence on what kind of stress produced them (history of deformation) and also because they change the characteristics of the rocks in which they occur. The Measured data of joints from the studied area which are located in the high folded zone – Northeast of Iraq, were classified according to their relationship with the tectonic axes by projecting them stereographically using Schmidt net in GEOrient ver.9.5.0 software. The joint systems revealed the orientation of the major stress field that caused the area deformation. Two dominant joint systems were found in most stations of the studied area, which are hko>a (first place) and hko>b (second place). The main stress field direction from the joint’s classification is North East – South West which coincides with the opening of the red sea and the collision between Arabian and Iranian tectonic plates. The North West direction (which comes in the second place) it might be due to the rotational movement (counterclockwise) of the Arabian plate in addition to the effect of local stress in the area.
