Surface subsidence of pit-in-pit foundation in sand–cobble stratum in Beijing area
Authors: Sun Yi , Zhao Yong , Zhang Dingli
Published: April 2018

A ‘pit in pit’ is a common problem in the excavation of foundation pits and yet this issue has not been researched systematically. The variability of its form not only complicates the condition of the surrounding stress and displacement fields, but also brings difficulty to design and construction. This paper analyses the surface subsidence features of pit-in-pit foundations based on the typical sand–cobble stratum in the Beijing area by applying finite-difference software. According to a comparison of three factors that affect the surface subsidence the most, a conclusion can be drawn that the depth of the inner pit is greater than the edge distance (from the inner pit to the wall of the outer pit), which is greater than the width of the inner pit. The application of stratum compensation theory to pit-in-pit engineering is discussed to analyse the relationship between the surface deformation and lateral displacement of retaining walls. The cause of inaccuracy is also discussed, although this was found to be within acceptable limits. The research findings provide guidance for engineering inspections and control during construction in pit-in-pit foundations in sand–cobble and other similar strata.
Use of nebulisers to deliver cementation liquid in granular soils to form biogrout
Authors: Dyer Mark , Viganotti Matteo
Published: April 2018

The use of urease enzyme to deposit calcium carbonate (CaCO3) for ground treatment of granular soils has typically relied on injection or percolation of liquid solutions. This approach can result in an uneven distribution of biogrout and loss of cementation liquid from percolation through the ground into the underlying groundwater system. As an alternative approach, laboratory experiments have demonstrated the potential of using aerosols to deliver fine micro droplets of reagent liquids into the unsaturated zone to promote calcium carbonate deposition at soil–particle interfaces. Scanning electron microscopy images taken of soil samples showed markedly different crystal morphology and particle bond formations for liquid percolation compared with aerosol injection methods. In particular, the bond formation created from aerosol droplets was found to replicate the curved surface of liquid menisci between soil particles, leading to a dual-bond meniscus structure. The resulting unconfined compressive strengths were comparable with similar increases in strength created from percolation and liquid-flushing methods. The results show the potential to use aerosol liquid delivery to promote ground improvement in the vadose zone for granular soils, where possible collapse of residual soils could be addressed, or to strengthen granular soils to resist additional forces such as earthquake loading.
Engineering behaviour of expansive clays blended with cement and GGBS
Authors: Phanikumar B. Ramachandra , Nagaraju T. Vamsi
Published: April 2018

This paper presents experimental data on the liquid limit (LL), plastic limit, plasticity index (PI), free swell index (FSI), optimum moisture content, maximum dry density (MDD), stress–strain behaviour and unconfined compressive strength (UCS) of an expansive clay blended with varying amounts of cement and ground granulated blast furnace slag (GGBS). Both cement and GGBS were independently added to the expansive clay up to 15% in increments of 5%. FSI, respectively, decreased from 145 to 100% and from 145 to 80% when cement and GGBS contents increased from 0 to 15%. LL and PI, respectively, decreased by 23 and 41% when cement content increased from 0 to 15%. Similarly, LL and PI, respectively, decreased by 14 and 30% when GGBS content increased from 0 to 15%. MDD increased, respectively, by 11 and 9·5% when cement content and GGBS content increased from 0 to 15%. The UCS of the cement–clay blends and the GGBS–clay blends increased with increasing additive contents. For a given additive content, UCS increased significantly with increasing curing period.
On the fundamental natural frequency of bridge decks: review and applications
Authors: Akbari Reza , Maadani Saeed , Maalek Shahrokh
Published: April 2018

The fundamental frequency of vibration of a bridge deck is a key parameter that represents the dynamic characteristics and the condition of the superstructure. This paper reviews the different empirical and/or theoretical formulae that have been proposed in the past. The classical vibration theory of beams and plates was simplified in order to clarify and review the general philosophy behind the previously proposed formulae. On the basis of the results obtained from limited dynamic tests performed by the authors on a number of reinforced concrete bridges and the results of limited tests conducted by other researchers, a formula for the first bending natural frequency of a bridge deck was derived. Moreover, as new applications, new practical formulae are introduced that can be used for estimating the initial dimensions of a deck cross-section for simple span bridges, which are particularly suited to bridge-widening projects. The first bending natural frequency/period of the bridge deck and its corresponding cross-sectional properties are considered here as functions of the bridge main span length.

Published: April 2018

In
this study, the relationships between
otolith dimensions and total length of chub (Squalius cephalus, L.1758) sampled from a few inland waters of Black Sea
was researched. Chub samples were obtained from the four different
localities (Abdal, Akçay, Terme and Yedikır). Power models were applied to estimate the
relationships between the otolith measurements and total length (TL).
Paired t-test, independent t test and ANOVA were done to test the data
statistically. The average total length of
individuals sampled from Abdal, Akçay and Terme Streams, Yedikır Dam Lake
varies between 11.49 ± 0.79 cm, 10.31 ± 0.52 cm, 10.33 ± 0.29 cm and 11.11 ±
0.33 cm, respectively. When all the data were evaluated according to
localities, it was found that there was no difference in terms of otolith breadth
(OB) and otolith length (OL) for asteriscus and lapillus
otoliths. There were differences in terms of otolith weight of lapillus in
localities. There were no differences of asteriscus otolith weight of chub
between localities.
The relationships between TL and OB, OL
and OW were determined using the power regression equation
and best fit was obtained between TL and OW for Terme (r2
=0.936) and Yedikır (r2 =0.912), OL for Akçay and Abdal Streams (r2=0.973).
A Corpus-based Study of Lexis in L2 English Textbooks
Authors: Norberg Cathrine , Nordlund Marie
Published: April 2018

Despite the fact that textbooks are central in foreign language learning, only limited research has explored to what extent L2 textbooks support language learning and whether the content in them is relevant from a vocabulary perspective. This study investigates the vocabulary in seven English textbooks used in Swedish primary schools. A corpus has been constructed based on the words in the textbooks. By means of a concordancing software tool, the material has been analyzed by comparing the vocabulary between the books and to words on the New General Service List and in the VP-Kids corpus. The analysis shows that many words in the textbooks occur only occasionally in common everyday language use. It also demonstrates that there is great variation in the number and selection of words across the books indicating that there does not seem to be a common thought behind word selection in textbooks used in Swedish schools.
The Relevance among Preservice English Teachers' Preparation Courses, Their Views about Teaching and Their Real Teaching Behaviors (A Case Study)
Authors: El-Sawy Hosam ElDeen Ahmed
Published: April 2018

This study aims at investigating the relevance among three factors: preservice English teachers' preparation courses, their views about teaching and their real teaching behaviors. This is a case study focusing on three preservice teachers of English in Egypt. Data was collected through three tools: an observation sheet, a semi-structured interview and a focus group. Results of the study revealed that there is a gap between what preservice English teachers learn in their preparation courses, their views about effective teaching and their real behaviors in class. The reasons which the participants gave for not applying what they have learned theoretically include: insufficient preservice training, students' low level, insufficient class time, students' resistance of changing the way they are used to learn, insufficiency of equipment in schools, students' preference of using the native language in learning, and in one case the teacher herself preferred the traditional grammar translation method. The study recommends early coordination between teacher preparation institutions and schools. The study recommends the incorporation of senior teachers in teacher preparation programs to try to breach the theory-practice gap. The study also recommends that teacher educators should analyze the given causes of the theory-practice gap and develop the English teachers' preparation courses in accordance.

Amprenta modelelor străine în secțiunea de morfologie a gramaticii lui Ioan Piuariu-Molnar (Deutsch-Walachische Sprachlehre, Viena, 1788)
Authors: Minuț Ana-Maria , Lihaciu Ion
Published: April 2018

Una din etapele pe care le-am parcurs în procesul de editare a gramaticii germano-române a lui Ioan Piuariu-Molnar a constat în identificarea modelelor urmate de autor. În literatura de specialitate este larg răspîndită afirmația că gramatica lui Molnar a avut ca model gramatica lui Samuil Micu și Gheorge Șincai, Elementa linguæ daco-romanæ sive valachicæ (Viena, 1780). Am constatat că, în cazul unor capitole ale gramaticii, se confirmă, în mod clar, influența acestui model. Există însă și capitole diferite de cele corespunzătoare din Elementa sau capitole care figurează doar în gramatica lui Molnar, nu și în cea a lui Micu și Șincai. Faptul se explică prin aceea că Molnar a urmat și modelul unor gramatici străine, care au avut în epocă un mare succes și o circulație intensă; este vorba de două gramatici ale limbii franceze, scrise în limba germană, cu terminologie gramaticală latinească: lucrarea lui J.R. des Pepliers, Nouvelle et parfaite grammaire royale françoise et allemande. Neue und vollständige königliche französische Grammatik, bisher unter dem Nahmen des Herrn der Pepliers vielmals herausgegeben (Leipzig, 1765, Tipografia M.G. Weidmanns Erben und Reich), respectiv gramatica lui Hilmar Curas, Erleichterte und durch lange Erfahrung verbesserte französische Grammatik (Berlin, 1759, Tipografia lui Friedrich Nicolai). În prezentul articol am relevat capitolele de morfologie în care este recognoscibilă influența gramaticilor lui Pepliers și Curas. Influența modelelor străine se reflectă în: organizarea internă a capitolelor, terminologia utilizată și corespondentele în limba germană ale cuvintelor; în privința ultimului aspect, am evidențiat, în studiul nostru, cazurile în care echivalentele germane indicate de Molnar pentru cuvintele românești sînt identice cu echivalentele germane indicate în gramatica lui Pepliers sau în cea a lui Curas pentru cuvintele din limba franceză.
Aparenta contrarietate

Există societăți în care mentalitatea individuală și cea socială sînt profund impregnate de religie, care domină ca filozofie de viață ce-și călăuzește supușii de la cele mai mărunte la cele mai importante gînduri și fapte. Acolo, viața laică este reflexia fidelă a ideologiei religioase și se petrece sub imperiul narativelor ei ancestrale și colective. Acolo, prezentul și viitorul celebrează un trecut mistic, reproducîndu-l printr-un efort circular și în condițiile lor.

Există societăți în care viața socială interferează nesemnificativ sau deloc cu cea religioasă, religia fiind doar tolerată, nu asimilată ori devoratoare. Acolo, ea nu este ghid ideologic, factor și forță atotcălăuzitoare, ci doar o paradigmă reminiscentă, prezentul și viitorul constituindu-se ca etape ale unei spirale evolutive.

O societate căreia religia i se impune ca forță ce tinde să conserve perpetuu starea de fapt, opunîndu-se evoluției de paradigmă, spre a păstra societatea pe linia uniformă a idealului impus, și o societate ce consideră că, de vreme ce realitatea fundamentală este materia supusă legităților interne, ideologia apare, există și devine prin și în chipul ființelor materiale supuse evoluției, peste dezvoltări și avatarii.

The aim of this work was to study the antitumor, anti-metastatic and metabolic effects of the newly synthesized n, π-chelate complexes Pt2+ with N-allythioureas (complex II and IU complex). The studies used high-metastable strain of transfected Lewis lung carcinoma and HepG2-transformed hepatocyte cells with high activity gamma-glutamate transpeptidases and mouse leukemia cells of L1210 with pronounced aneuploid karyotype and short duplication of population. In the comparative analysis with the classical chemotherapy cisplatin, the II and IV complexes revealed antitumor and anti-metastatic effects and normalization of biochemical disorders, which are confirmed by a decrease in the activity of lactate dehydrogenase and gamma-glutamine transpeptidase, indicating the inhibition of the formation of drug resistance.
Phenomenological Inquiry into Phoenix Rising Yoga Therapy
Authors: Sneed Jenilee , Hammer Tonya
Published: April 2018

There is growing recognition within psychology and other disciplines that body experience may be as important as cognitive and emotional experience. However, psychology has few psychotherapeutic interventions to support the integration of mind and body within therapy. Phoenix Rising Yoga Therapy (PRYT) is a form of mind-body therapy that uses yoga posture, touch, and psychotherapeutic dialogue to facilitate growth and healing. The current study explored the phenomenological experience of four women who each received five PRYT sessions. Research questions posed were: (1) What are the clients' experiences of the phenomena of PRYT? and (2) How does receiving PRYT sessions impact the clients' lives? The following themes emerged from the data as the essence of PRYT sessions: mindfulness, self-awareness, mind-body connection, in vivo experience of new behaviors, client-directed, empowerment, and life changes. These themes show significance in the mind-body connection and that it is important to consider alternative modalities such as PRYT for clients. Each participant noted greater insight into mind-body connection. They noticed the effect of cognition and emotion on the body, observed how the body can be used to improve coping through movement and breathing, and experienced different thoughts and emotions associated with different areas of their bodies. Although these results are not necessarily generalizable, they offer interesting theoretical implications for embodied interventions.

Published: April 2018

Objective: To assess caries incidence, intensity, and treatment in children and adolescents under/after antineoplastic treatment. Study design: Patients with permanent and mixed dentition were divided into three groups of 60 patients each (5–18 years): CH – under chemotherapy; PCH – after chemotherapy; CG – generally healthy subjects. Caries incidence, intensity (DMFT/dmft, DMFS/dmfs), and mean numbers of teeth/surfaces with white spot lesions–WSL (D1+2/d1+2) were assessed following the ICDAS-II criteria. Statistical analysis: Mann-Whitney U test, significance at p≤0.05). Results: Caries incidence was significantly higher in PCH and CH (88.33% and 90%) than in CG (66.66%). Caries intensity was higher in both mixed and permanent dentition in patients under and after chemotherapy. The DMFS/DMFT correlation was the highest in PCH. Treatment indexes for primary and permanent teeth treatment were significantly lower in PCH and CH than CG. Conclusion: Antineoplastic chemotherapy is associated with caries development and its high incidence during/after treatment. As dental hygiene was poor in patients under and after antineoplastic treatment, dental checkups need to be more frequent and thorough.

Background: Data are conflicting regarding the effect of professional staff attire on children at pediatric dental clinics. Aim: To compare the preferences of children and their parents in three countries, regarding the gender and attire of pediatric dentists. Study design: A multi-centered study was conducted in pediatric dental clinics in Israel (N=100), Uruguay (N=270) and Spain (N=200). Children, aged 4–12 years, and their parents were asked to choose the pediatric dentist they preferred from 5 pictures of the same male and 5 pictures of the same female, in different attire. Results: In Israeli clinics, where half of the pediatric dentists were male, and they wore white coats or casual attire, these were preferred by children, with no preference regarding the dentist's gender. In Spain, where the majority of dentists were females, wearing surgical scrubs, children preferred female dentists with this attire. In Uruguay, where female dentists wore surgical or pediatric scrubs, these were preferred by children. Parents more often selected female than male dentists; they preferred pediatric scrubs for their children's dentists more often than their children preferred such attire. Conclusions: Children's preferences for the attire of pediatric dentists reflected the common wearing apparel for dentists at the clinics they attended.

Introduction. Grip strength is a reflection not only of the strength of the hands, but also the strength of the muscles of the whole body, the functional capabilities of the body and an important diagnostic marker of the overall health of a person. The aim of this work was to compare the measurements obtained with the DK-50 and JAMAR® Plus digital handheld dynamometers.Methods. A convenience sample was used of 94 health participants, men and women, aged from 15 to 65 years old. Grip strength of a dominant hand was conducted using a carpal mechanical dynamometer DK-50 (Nizhni Tagil, Russian Federation) and JAMAR® Plus digital handheld dynamometer. The simple Pearson correlation test, linear regression method and the procedure of Bland and Altman were used to estimate difference between an average value of results of measurements of grip strength (AGS) and maximum measurement of grip strength (MGS) of the dominant hand of two dynamometers.Results. The grip strength using JAMAR® Plus dynamometer was higher than with the DK-50 dynamometer by 5.6 ± 4.2 kg for the average grip strength (AGS) and by 6.7 ± 4.3 kg for the maximum grip strength (MGS). The formulas for transferring the data of the car dynamometry of the DK-50 dynamometer to the values obtained from the JAMAR® Plus dynamometer are calculated: AGS JAMAR® Plus == 1,7874 + 1,1208 × AGS DK-50 and MGS JAMAR® Plus = 1.7667 + 1, 1275 × MGS DK-50.Conclusion. For avoiding errors in the interpretation of the results from different studies, it is necessary to take into account which type of dynamometer was used. The resulting formulas (AGS JAMAR® Plus == 1,7874 + 1,1208 × AGS DK50 and MGS JAMAR® Plus = 1,7667 + 1,1275 × MGS DK50) can be used to correct the data of the dynamometer DK-50 for value of JAMAR® Plus dynamometer and to compare the results of Russian studies with data from foreign studies organized using JAMAR® Plus dynamometers.

Authors: Barbosa Gomes Thalles Vicente , De Souza Tamara Daiane , Feliciano Braga Bruzze Patricia
Published: April 2018

O presente trabalho visa apresentar considerações sobre uma estratégia simplificada de tratamento de águas superficiais, empregando tanino Tanfloc SG e extrato de sementes de Moringa oleifera como coagulantes primários na tratabilidade dessa água para fins não nobres. Para avaliar a viabilidade do emprego destes coagulantes biodegradáveis e fazer um estudo comparativo entre a utilização deles foram realizados ensaios, utilizando o aparelho Jar Test com diferentes concentrações dos coagulantes e medições da turbidez em intervalos de sedimentação de 2 horas, além de diferentes faixas de pH. A Moringa oleifera não mostrou viabilidade na tratabilidade da água superficial. Verificou-se que a concentração de 5mg.L-1 de tanino Tanfloc SG, para um tempo de sedimentação de 2 horas, foi a que proporcionou a maior redução de turbidez (79%). A partir de diferentes faixas de pH (5 e 9), a Moringa oleifera não apresentou nenhuma eficiência. Já o tanino mostrou viabilidade, sendo que em pH 5 houve uma redução de 87,9% e em pH 9 a redução da turbidez foi de 87,72%. Os estudos referidos, no presente trabalho, sugerem haver um maior potencial de aplicação do tanino como coagulante primário, por ter apresentado maior viabilidade no tratamento da água bruta em relação ao extrato de sementes de Moringa oleifera.Palavras-chave: Turbidez. Moringa oleifera. Tanino.AbstractThe aim of the present study is to present considerations on a simplified surface water treatment strategy using Tanfloc SG tannin and Moringa oleifera seed extract as primary coagulants in the treatability of this water for non-noble purposes. To evaluate the viability of the use of these biodegradable coagulants and to make a comparative study between the use of them, tests were performed using the Jar Test apparatus with different concentrations of coagulants and turbidity measurements in sedimentation intervals of 2 hours and different pH ranges. Moringa oleifera showed no viability in the surface water treatability. It was verified that the concentration of 5mg.L-1 of tanfloc SG tannin, for a settling time of 2 hours, was the one that provided the greatest turbidity reduction (79%). From different pH ranges (5 and 9), Moringa oleifera showed no efficiency. The tannin showed viability, and at pH 5 there was a reduction of 87.9% and at pH 9 the turbidity reduction was 87.72%. The studies referred to in this work suggest that there is a greater potential for the application of tannin as a primary coagulant, as it has been shown to be more viable in the treatment of crude water regarding the Moringaoleifera extract.Keywords: Turbidity.

Hoy consideramos como una realidad prácticamente innegable que el Estado tiene una responsabilidad en la atención de los más necesitados, especialmente cuando se trata de niños. Sin embargo, y a pesar de los esfuerzos de intelectuales y legisladores, hasta fines del siglo XVIII, no se aprecian claros avances en esta materia. Nuestro trabajo pretende trazar el largo recorrido ideológico y jurídico que llevó a la promulgación de la Ley General de Beneficencia de 1849.

The data set reported here includes the part of a Hot Serial Cereal Experiment (HSC) experiment recently used in the AgMIP-Wheat project to analyze the uncertainty of 30 wheat models and quantify their response to temperature. The HSC experiment was conducted in an open-field in a semiarid environment in the southwest USA. The data reported herewith include one hard red spring wheat cultivar (Yecora Rojo) sown approximately every six weeks from December to August for a two-year period for a total of 11 planting dates out of the 15 of the entire HSC experiment. The treatments were chosen to avoid any effect of frost on grain yields. On late fall, winter and early spring plantings temperature free-air controlled enhancement (T-FACE) apparatus utilizing infrared heaters with supplemental irrigation were used to increase air temperature by 1.3Â°C/2.7Â°C (day/night) with conditions equivalent to raising air temperature at constant relative humidity (i.e. as expected with global warming) during the whole crop growth cycle. Experimental data include local daily weather data, soil characteristics and initial conditions, detailed crop measurements taken at three growth stages during the growth cycle, and cultivar information. Simulations include both daily in-season and end-of-season results from 30 wheat models. Data access via doi 10.7910/DVN/M9ZT0F

Published: April 2018

Background: Zygomaticomaxillary complex (ZMC) fracture is quite commonly seen fracture in the road side accidents (RTA). It is the second most common fracture after nasal bone fractures. Infraorbital nerve is almost always involved with ZMC fractures which can be treated with open reduction and internal fixation or closed reduction.

Methods: The aim of this study was to compare the recovery of infraorbital nerve paresthesia following open reduction and internal fixation verses closed reduction in the management of ZMC fractures.  

Results: Two groups with n=50 patients each, qualifying our inclusion criteria were selected, examined, reduced by open and closed reduction respectively and followed up.

Conclusions: The functional infraorbital nerve recovery was found among 74% patients those who underwent open reduction and internal fixation. While the patients treated with closed reduction the functional nerve recovery was seen in 52%.

Published: April 2018

Background: Post cricoid cancers are known to be treated with total pharyngo-laryngo-oesophagectomy (TPLO) with several reconstructive procedures described. This study aims at clinical symptoms in patients having hypopharyngeal cancer who underwent total pharyngo-laryngectomy with laparoscopic transhiatal oesophagectomy (TPLO) with gastric pull-up (GPU).

Methods: The clinical data of 13 patients undergoing TPLO with GPU during July 2013 to September 2017 were evaluated. All the patients had biopsy proven carcinoma. TPL was done and laparoscopic Transhiatal oesophagectomy was done and also the stomach was mobilized laparoscopically. The neostomach was delivered through posterior mediastinum and pharyngogastric anastomosis was done.  

Results: Only one patient (7%) had anastomotic stricture which required endoscopic dilatation, rest all the patients had no complications. So far they remain free of tumor recurrence or any other symptoms.

Conclusions: Laparoscopic GPU in a patient of TPLO should be the procedure of choice for maintaining the continuity of alimentary tract.

Published: April 2018

El subfilo Medusozoa (clases Cubozoa, Hydrozoa y Scyphozoa) se caracteriza por un esquema corporal predominantemente medusoide. El subfilo agrupa organismos con características pelágicas, lo que en cierta medida ha dificultado su conocimiento y estudio. En el Caribe colombiano se han registrado 25 de las 130 especies presentes en el mar Caribe, pero se considera que aún debe ahondarse en el conocimiento en torno a su diversidad local y regional. En este trabajo se registró la composición de las especies de Medusozoa presentes en algunas localidades del departamento del Atlántico, con énfasis en el sector turístico de Puerto Velero. Los registros se obtuvieron entre agosto de 2016 y diciembre de 2017. Las muestras se recolectaron de diversas formas: manualmente, utilizando arrastres superficiales con una red rectangular (1 mm de apertura de malla), o durante actividades de pesca. Se observaron siete especies: una de Hydrozoa, una de Cubozoa y cinco de Scyphozoa. Aurelia aurita y Chrysaora sp. fueron las más frecuentes en el sector de Puerto Velero. Aunque la mayoría de las especies son de distribución amplia o cosmopolita y ocasionalmente llegan a las costas del Caribe colombiano, en el Atlántico solo se tenía registro de una de ellas, por lo que estas observaciones amplían la información sobre su diversidad y frecuencia de aparición en esta zona del país, lo cual es de importancia para gestión y conservación en los lugares que desarrollan actividades turísticas. © 2018.

Published: April 2018

La caracterización de nanoburbujas de oxígeno en soluciones de NaCl ha sido efectuda con el objeto de estudiar la variación de su tamaño, concentración, pH, temperatura y niveles de agregación, a través de procesos de saturación de oxígeno y cavitación para diferentes tiempos. Las nanoburbujas fueron producidas mediante la inyección de oxígeno por rotación a la solución salina en un medio difusivo, a temperatura constante, en la procura de una solución con distribución homogénea. La solución finalmente obtenida fue sometida a varias pruebas, a varios tiempos diferentes, para observar los cambios en las nanoburbujas. La caracterización del tamaño de las nanoburbujas en la solución fue llevada a cabo utilizando la técnica de dispersión dinámica de la luz. La concentración de la solución se determinó mediante un proceso semicuantitativo teniendo en cuenta la concentración de partículas estándar y la tasa de conteo por segundo del dispositivo. Se midió el potencial ζ para establecer los niveles de agregación y estabilidad de las nanoburbujas a diferentes temperaturas y pH. A una temperatura T=4 oC, se observó que el diámetro de las nanoburbujas permanece aproximadamente constante en el tiempo (1000 to 2000 nm), independientemente de los valores de pH, alcanzándose la mayor estabilidad de las nanoburbujas.
