Cooperación técnico-científica internacional en la construcción de redes de monitoreo atmosférico. El caso de Bogotá (1960-2016)/ International Technical-Scientific Cooperation in the Construction of Atmospheric Monitoring Networks. The Case of Bogotá
Authors: Ángel Macías Mauricio Alberto , Gallini Stefania 
Published: March 2019

Las redes para el monitoreo de la calidad del aire en las ciudades se han posicionado como la tecnología útil para hacer seguimiento e intervenir sobre el peligro que trae consigo la contaminación atmosférica. La necesidad de hacer vigilancia atmosférica a escala global se ha fundamentado en la importancia de este problema ambiental para la salud pública, especialmente después de la segunda posguerra. La tecnología de monitoreo apareció en América Latina en los años sesenta, en un momento en el cual la contaminación del aire no suponía un problema mayor en la región. Aun así, se inició la vigilancia atmosférica, mediada por intereses económicos y políticos propios de las relaciones de poder internacionales características de este periodo. Este artículo toma como caso de estudio la ciudad de Bogotá, para explicar cómo las relaciones desequilibradas de poder entre países del primero y tercer mundo, y luego entre países desarrollados y en vías de desarrollo, condujeron a la creación de sistemas técnico científicos y redes de monitoreo atmosférico. Estas resultaron al principio más problemáticas que útiles, pero con el paso del tiempo se tornaron muy importantes para la vigilancia sanitaria y ambiental del territorio.
Abstract
Networks for air quality monitoring in cities have been positioned as useful technology to monitor and intervene on the danger posed by air pollution. The need to carry out global atmospheric monitoring has been based on the importance of this environmental problem to public health, especially after the second post war period. Monitoring technology appeared in Latin America in the 1960s, at a time when air pollution was not a major problem in the region. Even so, atmospheric surveillance was initiated, mediated by economic and political interests in the international power relations characteristic of this period. This article takes as a case study the city of Bogota, to explain how the unbalanced power relations between first and third world countries, and then between developed and developing countries, led to the creation of scientific technical systems and networks of atmospheric monitoring. These were at first more problematic than useful, but with the passage of time they became very important for the sanitary and environmental surveillance of the territory.
A Novel ZnO Nanoparticle as Drug Nanocarrier in Therapeutic applications: Kinetic Models and Error Analysis
Authors: Karakuş Selcan 
Published: March 2019

Nanotechnology
provides promising possibilities for several biomedical and pharmaceutical applications in
the medicine industry. Nanostructures play a major role in the recent
strategies of technology suitable for novel
drug applications. In this work, clindamycin phosphate (CliP) (topical
anti-inflammatory drug), xanthan gum (XaG) (biopolymer) and ZnO (zinc oxide) (nanoparticle)
nanostructures were synthesised using the sonochemical technique at room
temperature. The characterization of the clindamycin phosphate- xanthan gum/ZnO
(CliP-XaG/ZnO) nanostructure has been carried out by Fourier transform infrared
(FTIR) and X-ray diffraction (XRD). The spectroscopic experiments elucidated in
vitro the mechanism of drug delivery system at different pH media (1.2 and 7.4).
In this study, the concentration of drug in the solution was analyzed by UV–vis
spectroscopy method and several kinetic models and error analysis were
calculated to prove a connection with results. The Higuchi model had the best
correlation parameters. The percentage of swelling
ratio (%) reached up 105% in XaG (pH 1.2) and 190% in XaG/ZnO (pH 1.2) And the
swelling ratio (%) reached up 530% within in XaG (pH 7.4) and 655% within in
XaG/ZnO (pH 7.4). The results show that the capacity of XaG / ZnO can be
preferred as a novel topical anti-inflammatory drug carrier.
EPISTEMOLOGY OF ḤUḌÛRÎ IN SUHRAWARDÎ AL-MAQTÛL’S ḤIKMAT ISHRÂQIYAH
Authors: Habib Zainal 
Published: March 2019

The epistemological thinking of ḥuḍûrî in Ḥikmat al-Ishrâqiyah Suhrawardî has provided a new direction for the development of Islamic knowledge. In the ontological perspective, the idea of illumination provides an understanding that there is an extensive range of realities, stretching indefinitely, which ultimately leads to the understanding of essentialism. Suhrawardî's success in bringing forth this illuminative thinking entails his profound mastery of philosophy and Sufism, as well as his high intelligence in formulating Islamic thought. The only solution to the problem of developing knowledge according to Suhrawardî, lies in the reality of ḥuḍûrî (knowledge with presence), in which there are many dialogues about 'subjects who know' or 'I am performative'. In this concept, oneself knows itself through the science of ḥuḍûrî (knowledge with presence), which is existentially identical to the form of 'oneself' itself.
Application of high-throughput 16S rRNA sequencing to identify fecal contamination sources and to complement the detection of fecal indicator bacteria in rural groundwater
Authors: Naphtali Paul , Mohiuddin Mahi M. , Paschos Athanasios , Schellhorn Herb E. 
Published: March 2019

Abstract
Residents in rural communities across Canada collect potable water from aquifers. Fecal contaminants from sewage and agricultural runoffs can penetrate aquifers, posing a public health risk. Standard methods for detecting fecal contamination test for fecal indicator bacteria (FIB), but the presence of these do not identify sources of contamination. In contrast, DNA-based diagnostic tools can achieve this important objective. We employed quantitative polymerase chain reaction (qPCR) and high-throughput DNA sequencing to trace fecal contamination sources in Wainfleet, a rural Ontario township that has been under the longest active boil water advisory in Canada due to FIB contamination in groundwater wells. Using traditional methods, we identified FIBs indicating persistent fecal pollution in well waters. We used 16S rRNA sequencing to profile groundwater microbial communities and identified Campylobacteraceae as a fecal contamination DNA marker in septic tank effluents (STEs). We also identified Turicibacter and Gallicola as a potential cow and chicken fecal contamination marker, respectively. Using human specific Bacteroidales markers, we identified leaking septic tanks as the likely primary fecal contamination source in some of Wainfleet's groundwater. Overall, the results support the use of sequencing-based methods to augment traditional water quality testing methods and help end-users assess fecal contamination levels and identify point and non-point pollution sources.

Students’ attitude towards Undergraduate Foundation Mathematics Remediation in a HE institution in a Gulf Country
Authors: Santhanam Nehru Erode , Shrivastava Ritu , Toworfe George 
Published: March 2019

This study outline causes why Foundation Mathematics students are reluctant to access support and remedial structures that are put in place to enable them to achieve their academic goals. The study was conducted using a survey method which included administering a structured questionnaire and one-to-one focused group discussions with students. The study aims to discuss the common tendency of students towards mathematics remediation programmes. This study centred on students’ perceptions regarding the teaching & Learning of Mathematics, specifically, however, the educational surroundings impacts their perceptions as students of Mathematics in terms of confidence, anxiety, enjoyment, motivation, and therefore the connection of Mathematics in personal and skilled Experiences. Data obtained from this study indicated that factors contributing to poor performance include lack of motivation, poor attitude of students towards Mathematics courses and retrogressive practices. It is envisaged that rising on these factors and sensitization of students to discard practices that proscribe learner’s effective participation in finding out the topic may improve their performance in mathematics. It is likely that improved mathematics performance will give learners opportunities to pursue mathematics-related HE degree programmes at higher institutions of learning.
The Pragmatic Presuppositions of somebody/someone in Christian Religious Discourse in Nigeria
Authors: Dada Samuel Ayodele , Mercy Omoregbe Esohe 
Published: March 2019

The study examines the pragmatic presuppositions of somebody and someone as being employed by preachers in Christian ministration discourse in Nigeria. The study aims at investigating the pragmatic motivations behind the use of these pronouns in Churches by preachers. The study identifies the necessity of the context of situation as the major reason behind the use of these pronouns. Indeed, somebody is here is the language of God to His people in such an occasion. The study has once more brought to the fore the merit of the campaign that a writer/speaker needs good training not only in the grammatical competence but also in the communicative competence of the language with which he operates.
European Portuguese Phonetics: Difficulties for Chinese Speakers - Considerations
Authors: Nunes Ana Margarida 
Published: March 2019

The present paper is a pilot study focusing the common difficulties that either Mandarin or Cantonese speakers present on writing Portuguese. The observed problems are an obstacle on the accurate learning of European Portuguese and are related with the Portuguese minimal pairs [p]/[b]; [t]/[d]; [k]/[g] that are often misunderstood. Those specific examples the use of [p] instead of [b] may create a new word but also a different meaning, as example: (small boat) instead of (big vase), or (not existing) instead of (receive). Works of 25 students were selected and 43 occurrences analyzed. Recognizing the limitations of the present research the results show that the prevalent confusion is with the pair [t]/[d] when in CCV context. The study (although recognizing its limitation) should be seen as approaches and reflections that must be deeply studied and data being important to Second Language Teachers and researchers.
Discourse Analysis: Contextualism and Reductionism
Authors: Majidi Setareh 
Published: March 2019

For the past twenty to thirty years, a good part of the domain of linguistics has been occupied by what has been called discourse analysis. Whereas syntax and semantics are concerned by the sentence and the units from which the sentence is built, discourse analysis claims that interpretation cannot accounted for at the level of the sentence and that a bigger unit, such as discourse should be used to account for language interpretation. We want to show here that discourse is not, in any sense, a well defined object and that, though it is certainly necessary to analyze how a given sequence of sentences is processed and understood, the notion of discourse, A and related notions such as coherence does not have much to say about it. We rely on epistemological considerations about the necessity of a moderate reductionism and sketch on account of linguistic interpretation which accounts for contextual factors in linguistic interpretation through the notion of utterance (vs. sentence) and a development of Sperber & Wilsons Relevance Theory.
The Role of Explicit Knowledge, Noticing, and Attention in L2 Writing and Error Correction: Quantitative and Qualitative Analyses
Authors: El-dali Hosni M. El-dali 
Published: March 2019

This study attempted to find answers for the following questions: (1) Are students errors in grammatical structures, as they will appear in their written output, due to deficiency in their conscious grammar rules, or to deficiency in their abilities to transfer this knowledge (if it exists) to other language tasks such as writing compositions in English?, and (2) Can conscious rules of grammar guide students' performance in monitoring (self-correcting) their written output once their attention is drawn to an error?. The subjects of this study consisted of fifteen foreign students enrolled in the advanced level of the English Language Institute at the University of Pittsburgh. The instruments of this study were (1) questionnaire; (2) free composition; (3) unfocused correction and focused correction tasks; and (4) interviews. The results of this study demonstrate, among other things, that deficiency in the subjects knowledge of grammar results in accurate composition writing and unsuccessful correction of errors, even if their attention is drawn to their errors.
Comparison of Quantities of Information in the Human Memory
Authors: Dishliev Angel Angelov , Girginov Christian Assenov , Dishlieva Katya Georgieva 
Published: March 2019

A mathematical model of changing the amount of information in the abstract human memory is proposed in the presence of the subsequent "external discrete" training (filling the information). Under this model, the amount of information is a solution of impulsive differential equation with fixed moments of impulsive effects and variable structure. Sufficient conditions are proposed related to the moments and magnitudes of the impulsive effects (i.e., to the moments of discrete training and the volume of the received information), where the quantities of information in two different models of learning can be compared.
On Twisted Sums of Sequence Spaces
Authors: Bin Jebreen Haifa Mohammed 
Published: March 2019

We prove the existence of non trivial twisted sums involving the pth James space Jp(1 < p < 1), the Johnson-Lindenstrauss space JL; the James tree space JT , the Tsirelson’s space T and the Argyros and Deliyanni space AD . We also present non trivial twisted sums involving their duals and biduals. We show that there are strictly singular quasi-linear maps from the spaces T ;T* ; AD and JT into C[0; 1]. We discuss the Pelczynski’s property(u) for the twisted sums involving these spaces which extends a pthJames-Schreier spaces Vp(1 < p <1) or J2.
