HERMITE NUMERICAL METHOD TO ESTIMATE THE RADON AND RADIUM EFFECTS OF THE SOIL IN BARTELLA REGION
Authors: Mustafa Hekmat SH. , Kheder Malik H. , Mahmood Sarah Ghanim
Published: April 2020

The Hermite numerical interpolation method used to estimate and predict the radon and radium concentrations, from some of the experimental measurements made on the soil samples of the Bartella region in Iraq. The results obtained from deductible mathematical method were close to real experimental results. Predicted results are in the range of 80.04–4051.59 Bq/m3radon concentrations and 0.322–17.276 Bq/Kgradium concentrations corresponding to 200-10000 tracks of alpha particles. The maximum errors were less than 0.289 and 1.172 percent for radon and radium concentrations, respectively. The effects of radium and radon radiations estimated of soil in the studied area depend on its concentrations, a higher number of alpha particle tracks mean high radiation concentration, the high radiation will cause human health damage. The values are below 370 Bq/Kg the recommended radium concentration permissible values, by the Organization ащк Economic Cooperation and Development (OECD), the studied area is safe from hazards on health of radium and radon exposure from the soil

Motivational Board is developed individually by each patient on the basis of a single algorithm, which makes it a personal instrument of the patient. The method described in the article makes it possible to change the patient's train of thought and behavioral strategy without excessive efforts. Motivational Board has a game format, which helps to create a positive internal motivation and shows the patient that how to control the illness and register the progress. As a result, the patient feels the need to control his or her life by supporting the necessary lifestyle. The experiment results confirmed the didactic effect of the method.
The Image of the Representatives of the United States and China as seen by Vladivostok Students
Authors: Marin E. B. , Kalita V. V.
Published: April 2020

The research featured the image of the "typical American" and "typical Chinese" as seen by Russian students of several Vladivostok universities. The reconstruction of ethnic stereotypes was performed using the methods of psychosemantics, e.g. verbal associations. The data were processed using mathematical statistics methods. The study revealed major differences in the representation of positive and negative personal qualities of the "typical Chinese" and "typical American", as well as in the contents of the association categories. Students’ perceptions of the "typical American" showed both positive (sociability, activity, tact) and negative qualities (hypocrisy). The "typical Chinese" was often perceived as an unattractive, loud, and racist representative of a de-individualized mass. However, the "typical Chinese" was also described as a hard-working and moderately sociable person that lives in a Communist country with a vibrant traditional culture and modern industry. Americans were seen as much more individualized, as confirmed by quantitative and semantic analyses. The survey revealed superficial and mostly negative views of young Russians regarding the Chinese people. The authors believe that a more positive attitude has to be formed as China remains Russia’s strategic partner
Word-formative Nomination in the English Terminology of the Mixed Martial Arts
Authors: Dronyakina N. V. , Starykh D. A.
Published: April 2020

The research featured the English terms related to the sphere of mixed martial arts (MMA) and their word-formation. A detailed analysis of the structure of MMA terms made it possible to distinguish one-, two-, three-, four-, and polycomponential terminological units. One-componential terms were represented by linguistic units expressed by a word with different morphemic composition. Two-componential terms were represented by word-combinations with a noun, an adjective, or a verb (or its forms) as their core elements. Via complex contraction, three- and four-componential terminological units could be transformed into abbreviations. The polycomponential terminological units were few and expressed by gerund word-combinations. The research also revealed related principles of nomination and formation: semantic, morphological, and syntactical. The semantic way was realized via indirect nomination, i.e. metaphor and metonymy. The morphological way was represented by affixation, compounding, and abbreviation. The syntactic way was used to coin the MMA terms expressed by word combinations and gerund word-combinations. The paper focuses on the dominant models and the key types of terminological word-combination, e.g. substantive and attributive
Settlement of the Kiya River Basin by the Russians: Case Study of the Foundation of the Village of Сhumay in the Chebulinsky District of Kemerovo Region
Authors: Kuzmin O. Yu.
Published: April 2020

The present research featured the development of the Northern Kemerovo region. The paper focuses on the case of the village of Chumay in the Kiya river basin. The development of Russian settlements along the Kiya remains understudied. Existing publications give different foundation dates for the villages in the area of Prichulym'e. The Russians first came to the Kiya basin in the early XVII century. However, they were slow to settle down for a number of reasons. First, it was the military confrontation with the Yenisei Kirghiz. Second, the local taiga and mountains were impassable and unsuitable for farming. In addition, the existing communication routes were far from the Kia basin. The article describes the prerequisites and conditions for the emergence of Russian villages in this territory. The research was based on rare historical sources, e.g. memoirs of local residents and parochial documents, related to the foundation of the village of Chumay located in the Chebulinsk district of the Kemerovo region. The research revealed the settling process and some new data on the first settlers. The findings refute the thesis that this territory of the Kemerovo region was settled exclusively by fugitives and exiles in the XVII–XVIII centuries. The Russian advanced into the Kiya river basin after the military threat from the Kirghiz had been eliminated. Second, the indigenous peoples were converted to Christianity and had to pay tribute in furs. Third, a section of the Moscow-Siberian tract was built in the vicinity. Finally, voluntary migrants willing to settle down in the area were given a free piece of land. Unlike the rest of the Kemerovo region, the lands along the Kiya river were colonized by the Russians much later. The government colonization was organized and started "from above". It was represented mainly by voluntary immigrants. The research also revealed the role of migrants from the Caucasus in the development of the Kiya basin as they set up new settlements and went to live in sparsely populated villages.

Published: April 2020

The present article introduces a new complex approach to the Russian rural settlements of the XVII – early XX centuries in the Middle Tom' Region basin. The approach unites historical, archaeological, and ethnographic researches for a detailed reconstruction of the process of Russian colonization in the region and its reflection in the local material culture. A thorough analysis of historical documentation made it possible to describe the development of the peasant population in the Middle Tom' Region valley. The four stages of this process are different in growth rates, as well as in the priority role of the southern and northern zones of the region. The XVII century saw the most active process of rural development in Sosnovsk area, while the settlements of Kuznetsk area appeared mostly in the first half of the XVIII century. The growth rate in the north and south areas began to level in the second half of the XVIII century – early XIX century. There were no changes in the total number of settlements registered after the middle of the XIX century. The paper also features a brief analysis of archaeological studies of the rural settlements in Western Siberia. The authors believe that the Middle Tom' Region basin still remain largely understudied. The paper contains a catalog of the local archaeological monuments of the Early Modern Period. The catalog is based on the coverage degree, historical identification, and their protection status. The research revealed a certain territorial disproportion in the number of registered archeological monuments. The authors propose some new directions for further studies of the history and culture of the Russian population in the Middle Tom' Region basin.
Artifactual Remains from the Kushek-4 Site in the South of Turgai Depression
Authors: Podzuban E. V.
Published: April 2020

The present article features a collection of prehistoric artifacts obtained at the Kushek-4 site. The excavations were conducted along the right bank of the Uly-Zhylanshik river in the south of the Turgay in 2006. The stone tools collected from the surface underwent a technical and typological analysis, which made it possible to date the site. The main parameters of the technical and typological analysis included primary rock flakes, morphological parameters and size of the plates, percentage ratio of ingots and tools from plates and rock flakes, methods of secondary processing, and the typological composition of the tool kit. The nature of the raw materials was an independent indicator. The technical and typological indicators of the stone tools from the Kushek-4 site corresponded to the second group of monuments of the Turgay Depression with their rich Neolithic material. The stone tools were homogeneous and dated from the late Mesolithic to the late Neolithic.

Jerusalem and the border, evolutive aspects
Authors: Salenson Irene
Published: April 2020

What meaning does the term border take on referring to a city? The city of Jerusalem is an interesting case study because with it the whole polysemy of the word border shows up, on every geographical scale. Since the start of the Al- Aqsa Intifada in 2000, support for the idea of a physical barrier between Israel and the Palestinian territories has grown tremendously among Israelis. On Jerusalem´s external boundary, this barrier takes the form of an eight-metershigh- wall. The Israeli government does not admit that the barrier’s sole purpose was the prevention of terrorist incursions. A policy of ethnic separation was clearly intended, the argument being that co-existence between Israelis and Palestinians had been a failure. How did the Holy city reach this pessimistic point, considering that the idea of an international city was proposed twice in the first half of the twentieth century, when its inhabitants had already suffered a separation between 1948 and 1967, and when a peace process had been initiated in 1994? Will this barrier become the new border between Israel and Palestine, between West and East Jerusalem? Keywords: Jerusalem, frontier, separation fence, municipal territory, international city.
Los paradigmas científicos frente a los retos del significado axiológico en la educación
Authors: Mungaray Lagarda Marcela
Published: April 2020

Los valores desde la ética o desde las pautas de comportamiento social han implicado una serie de contenidos que, bajo distintas racionalidades o intencionalidades paradigmáticas, conforman un sentido integrador del valor del ser en el mundo. El objetivo de este texto es fundamentar que la polisemia en este campo y, por ende, la confusión de los planteamientos formativos respecto al valor, se pueden abordar desde la comprensión de los distintos campos paradigmáticos en que la ciencia construye sus campos de conocimiento y atribuye valores intrínseca y extrínsecamente a los procesos cognitivos. La conciliación entre los paradigmas no es cosa fácil ya que cada cuerpo de conocimientos implica la comprensión del mundo bajo estructuras cognitivas que dan cuenta de sus propios valores no necesariamente universales, dado que la presentación de sus objetos de conocimiento convoca ya la inclusión o exclusión de un campo valoral donde la cientificidad de cada planteamiento cobra sentido. La teoría del valor genera, pues, estructuras comprehensivas que serán planteadas desde tres ámbitos paradigmáticos: empírico-analítico, estructural-hermenéutico y crítico-sistémico. Palabras clave: valores, axiología, paradigmas, educación.
Integración comercial de la industria agroalimentaria mexicana en el marco del TLCAN
Authors: Acosta Martínez Ana Isabel , Álvarez Aledo Carlos
Published: April 2020

El TLCAN ha facilitado el comercio entre los países socios al definir las reglas del juego, pero aún no está demostrada claramente su contribución al desarrollo económico y bienestar. Los modelos tradicionales de comercio internacional predicen que en presencia de libre comercio, si los países mantienen grandes diferencias en su relación capital-trabajo, es de esperar que el comercio se base en las ventajas comparativas y sea del tipo interindustrial, provocando ajustes estructurales en los sectores acompañados de altos costos sociales por la reestructuración, a diferencia de la especialización intraindustrial. Ésta puede ser una explicación causal del fenómeno de la desarticulación de las cadenas productivas del sector agroalimentario mexicano, manifestado por el crecimiento de la industria de alimentos a expensas de las importaciones de materias primas agrícolas, aumentando la dependencia al mercado exterior. Palabras claves: TLCAN, integración comercial, industria agroalimentaria, especialización intraindustrial.
Inmigrantes marroquíes en el sector agrario andaluz
Authors: Izcara Palacios Simón Pedro
Published: April 2020

En Andalucía (España), la falta de mano de obra local dispuesta a aceptar los salarios y las condiciones laborales imperantes en la agricultura de exportación, aunada a un aumento en la producción de frutas y hortalizas recogidas a mano, ha incrementado la dependencia de los empresarios agrarios de mano de obra inmigrante, procedente principalmente de Marruecos. Más aún, en el sector agrario un elevado nivel de trabajo irregular es el resultado de la coexistencia de leyes restrictivas y la disposición de los empresarios agrarios de romper la ley a fin de emplear mano de obra barata, flexible, no sindicalizada y legalmente indefensa, con objeto de reducir costos e incrementar los beneficios económicos. Además, en una atmósfera de creciente xenofobia en contra de los marroquíes, las condiciones de los trabajadores agrarios procedentes de Marruecos son especialmente precarias. Asimismo, las condiciones de vivienda son rudimentarias y la mayoría de ellos viven hacinados. Este artículo, fundamentado en una metodología cualitativa, analiza la situación sociolaboral de los trabajadores marroquíes empleados en la agricultura andaluza, región situada en el sur de España.

Authors: Mendoza Cifuentes Humberto
Published: April 2020

Background and Aims: Wurdastom is a little-known neotropical genus, which is poorly represented in herbarium collections. A historical summary,discussion about the tribal position, taxonomic review, and a conservation assessment of each species of the genus was carried out.Methods: Wurdastom specimens of 17 herbarium collections from Colombia (CAUP, COAH, COL, CUVC, FMB, HUQ, PSO, UDBC, UPTC, VALLE), Ecuador (QCA, QCNE), and the United States of America (CAS, F, MO, NY, US) were reviewed, and relevant type collections available at JSTOR Global Plants were consulted. An identification key, descriptions, illustrations and distribution maps for each species were developed. IUCN guidelines and criterio were used for conservation assessments of each species.Key results: In total, 52 Wurdastom collections were found in the revised herbaria. A new species from Colombia is described and new isotypes from the VALLE Herbarium are reported here for the first time. Wurdastom is a small genus of trees and shrubs from central-west Colombia to northern Peru where it grows in Andean and humid lowland tropical forests. The genus, which is assigned to the tribe Cyphostyleae, is characterized by the acrodromous venation, barbellate trichomes on vegetative parts and inflorescences, multiflorous thyrsoid or pleiothyrsoid inflorescence, haplostemonousflowers, petals ≤1 cm long, inferior ovaries, and capsular fruits.Conclusions: Wurdastom includes eight neotropical species, most of them with restricted distributions. One species is assessed here as Threatened (W. sneidernii), two as Vulnerable (W. cuatrecasasii, W. dudleyi), and the rest are treated as Data Deficient.

This study presents an overview of Malaysian adolescent field hockey players’ expectancy beliefs, subjective values and sportspersonship attitude. We aimed to translate and validate two questionnaires i.e., Expectancy Value Model Questionnaire (EVMQ) and Multi-dimensional Sportspersonship Orientations Scale (MSOS) to Malay language. The EVMQ and MSOS were translated into the Malay language using the back translation method. A total of 230 respondents (15.40 ± 2.17 years) were recruited for this study.  The result of analyses are EVMQ-M (M = 5.38 ± .95) and MSOS-M (M = 3.64 ± .40) respectively. Content validity was checked by experts in the fields for content conformity and culture bias whereas face validity was confirmed by ten participants. Both questionnaires showed high internal consistency (reliability); EVMQ-M (α = .94) and MSOS-M (α = .82). Data fits were checked using the Structural Equation Model; EVMQ-M (χ² (df = 39) = 84.07, CFI = .97, GFI = .94, TLI = .95, RMSEA = .07, ChiSq/df = 2.16) and MSOS-M (χ² (df = 146) = 321.76, CFI = .92, GFI = .87, TLI = .90, RMSEA = .07, ChiSq/df = 2.20) also showed good construct validity. The translated Malay version EVMQ-M and the MSOS-M are reliable and valid instruments to assess Malaysian adolescent field hockey players.

Published: April 2020

Indonesian university graduates skills in creating job opportunities or entering the workforce are still low. It can be seen from the facts that the undergraduate unemployment rate is still higher than the national unemployment rate. Although entrepreneurship education has been considered as one solution to this problem, the best entrepreneurship education model has not been agreed among researchers. This study examines the application of Business Model Canvas (BMC) on enhancing student achievement and student entrepreneurial intentions and the interaction of entrepreneurial learning achievement levels and the application of BMC on entrepreneurial intentions. The method used in this research is quasi-experiment by assigning two classes of entrepreneurship courses at the Faculty of Economics, Medan State University, one class as an experimental class (BMC) and the other class as the control class. Hypothesis testing was conducted with t-test and ANOVA. The findings showed that the average entrepreneurial learning achievement of the BMC class was 12.52% higher than that of the control class. Entrepreneurial intentions of the BMC class was only 6.15% higher than that of the control class. BMC is proven to be positive and significantly improves learning achievement. The level of learning achievement is proven to be positive and it significantly increases entrepreneurial intentions. However, BMC learning has not been proven to increase entrepreneurial intentions. The results of this study are useful for entrepreneurial instructors to design learning that can increase entrepreneurial intentions.

Published: April 2020

Desde 2012 o Departamento Nacional de Infraestrutura de Transportes (DNIT) vem utilizando o Regime Diferenciado de Contratação (RDC) e pesquisas estão sendo realizadas para verificar a efetividade dos seus objetivos. A proposta deste artigo consiste na avaliação das contribuições relacionadas à eficiência na aplicação do RDC nas obras de infraestrutura de transportes do DNIT. Para tanto, foram verificados prazos de licitações, descontos ofertados e o número de concorrentes de 91 lotes de obras de RDC, cujos editais de licitação foram divulgados no período de 2015 a 2017, nas diversas unidades regionais do DNIT e na sua sede em Brasília. Ao comparar os valores obtidos com os encontrados na bibliografia, observa-se que nas licitações de RDC houve uma redução nos prazos médios dos certames e um aumento no desconto médio ofertado, sendo mais evidente quando os orçamentos não são sigilosos. Os resultados da pesquisa contribuem como referência aos legisladores que pretendem aprimorar ou popularizar o RDC, bem como aos gestores do DNIT na condução dos processos licitatórios.

Novel Coronavirus in Cape Town Informal Settlements: Feasibility of Using Informal Dwelling Outlines to Identify High Risk Areas for COVID-19 Transmission From A Social Distancing Perspective
Authors: Gibson Lesley , Rush David
Published: April 2020

Background

The challenges faced by the Global South during the coronavirus disease (COVID-19) pandemic are compounded by the presence of informal settlements, which are typically densely populated and lacking in formalized sanitation infrastructure. Social distancing measures in informal settlements may be difficult to implement due to the density and layout of settlements. This study measures the distance between dwellings in informal settlements in Cape Town to identify the risk of COVID-19 transmission.

Objective

The aim of this paper is to determine if social distancing measures are achievable in informal settlements in Cape Town, using two settlements as an example. We will first examine the distance between dwellings and their first, second, and third nearest neighbors and then identify clusters of dwellings in which residents would be unable to effectively practice social isolation due to the close proximity of their homes.

Methods

Dwellings in the settlements of Masiphumelele and Klipfontein Glebe were extracted from a geographic information system data set of outlines of all informal dwellings in Cape Town. The distance to each dwelling’s first, second, and third nearest neighbors was calculated for each settlement. A social distance measure of 2 m was used (buffer of 1 m, as dwellings less than 2 m apart are joined) to identify clusters of dwellings that are unable to effectively practice social distancing in each settlement.

Results

The distance to each dwelling’s first 3 nearest neighbors illustrates that the settlement of Masiphumelele is constructed in a denser fashion as compared to the Klipfontein Glebe settlement. This implies that implementing social distancing will likely be more challenging in Masiphumelele than in Klipfontein Glebe. However, using a 2-m social distancing measure, it was demonstrated that large portions of Klipfontein Glebe would also be unable to effectively implement social distancing.

Conclusions

Effectively implementing social distancing may be a challenge in informal settlements due to their density. This paper uses dwelling outlines for informal settlements in the city of Cape Town to demonstrate that with a 2 m measure, effective social distancing will be challenging.
Conducting Clinical Research During the COVID-19 Pandemic: Investigator and Participant Perspectives
Authors: Padala Prasad R , Jendro Ashlyn M , Padala Kalpana P
Published: April 2020

As the medical landscape changes daily with the coronavirus disease (COVID-19) pandemic, clinical researchers are caught off-guard and are forced to make decisions on research visits in their ongoing clinical trials. Although there is some guidance from local and national organizations, the principal investigator (PI) is ultimately responsible for determining the risk-benefit ratio of conducting, rescheduling, or cancelling each research visit. The PI should take into consideration the ethical principles of research, local/national guidance, the community risk of the pandemic in their locale, staffing strain, and the risk involved to each participant, to ultimately decide on the course of action. While balancing the rights and protection of the human subject, we seldom examine patients’ views and opinions about their scheduled research visit(s).
This article discusses the ethical principles of beneficence and autonomy in helping the decision-making process. We discuss ways to weigh-in local and national guidance, staffing strain, and institutional support into the decision-making process and outline potential changes needed for regulatory bodies depending on the decision. Further, we discuss the need to weigh-in the individual risk-benefit ratio for each participant and present a decision tree to navigate this complex process. Finally, we examine participant and caregiver perspectives on their fears, sense of preparedness, and factors that they consider before deciding whether to keep or postpone the research appointments. This entry also provides PIs ways to support their research participants in both scenarios, including provision of psychological support.
Interrelationships Between Patients’ Data Tracking Practices, Data Sharing Practices, and Health Literacy: Onsite Survey Study (Preprint)
Authors: Luo Yuhan , Oh Chi Young , Jean Beth St , Choe Eun Kyoung
Published: April 2020

BACKGROUND

Although the use of patient-generated data (PGD) in the optimization of patient care shows great promise, little is known about whether patients who track their PGD necessarily share the data with their clinicians. Meanwhile, health literacy—an important construct that captures an individual’s ability to manage their health and to engage with their health care providers—has often been neglected in prior studies focused on PGD tracking and sharing. To leverage the full potential of PGD, it is necessary to bridge the gap between patients’ data tracking and data sharing practices by first understanding the interrelationships between these practices and the factors contributing to these practices.

OBJECTIVE

This study aims to systematically examine the interrelationships between PGD tracking practices, data sharing practices, and health literacy among individual patients.

METHODS

We surveyed 109 patients at the time they met with a clinician at a university health center, unlike prior research that often examined patients’ retrospective experience after some time had passed since their clinic visit. The survey consisted of 39 questions asking patients about their PGD tracking and sharing practices based on their current clinical encounter. The survey also contained questions related to the participants’ health literacy. All the participants completed the survey on a tablet device. The onsite survey study enabled us to collect ecologically valid data based on patients’ immediate experiences situated within their clinic visit.

RESULTS

We found no evidence that tracking PGD was related to self-reports of having sufficient information to manage one’s health; however, the number of data types participants tracked positively related to their self-assessed ability to actively engage with health care providers. Participants’ data tracking practices and their health literacy did not relate to their data sharing practices; however, their ability to engage with health care providers positively related to their willingness to share their data with clinicians in the future. Participants reported several benefits of, and barriers to, sharing their PGD with clinicians.

CONCLUSIONS

Although tracking PGD could help patients better engage with health care providers, it may not provide patients with sufficient information to manage their health. The gaps between tracking and sharing PGD with health care providers call for efforts to inform patients of how their data relate to their health and to facilitate efficient clinician-patient communication. To realize the full potential of PGD and to promote individuals’ health literacy, empowering patients to effectively track and share their PGD is important—both technologies and health care providers can play important roles.

The low yield of rice in thick peat can be overcome by provisioning complete nutrients. Various efforts have been made to increase the productivity of Indonesian peatlands, one of which is by adding salted fish waste and cow manure. This research was carried out on a plastic house scale from October 2017 to January 15, 2018, in Pelalawan District, Pelalawan Regency, Riau. This research was arranged in a Completely Randomized Design (CRD), consisting of eight treatments, namely L0 = Control, L1 = 1.5 ton.ha-1 of fish waste, L2 = 2.25 ton.ha-1 of fish waste, L3 = 7 tons/ha of cow manure, L4 = 15 ton.ha-1 of cow manure, L5 = 1.5 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, L6 = 1.5 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure, L7 = 2. 25 ton.ha-1 of fish waste + 7 ton.ha-1 of cow manure, and L8 = 2.25 ton.ha-1 of fish waste + 15 ton.ha-1 of cow manure. The results showed that the application of cow manure and salted fish waste could increase soil pH, total NPK, and NPK uptake. The application of 2.25 tons/ha of fish waste and 15 tons/ha of cow manure resulted the best results in soil pH, total NPK, and NPK uptake, therefore it is recommended for the cultivation of lowland rice on peat soil.

Authors: HARDIKAR SHARWAREE R. , MULLA SHAKIL S.
Published: April 2020

Objective: The present study aimed to improve the rate of dissolution of furosemide by solid dispersion technique.

Methods: Solid dispersion of furosemide was prepared by using hydrogel isolated from the seeds of Lepidium sativum as a novel carrier by the solvent evaporation method. Solid dispersion was evaluated to study the improvement in the rate of dissolution. Molecular dispersion of furosemide in the novel carrier was studied by DSC and FTIR studies. Solid dispersion was filled in capsules after stability studies and the formulation was optimized by adopting factorial design.

Results: Solid dispersion of furosemide exhibited dissolution improvement from 13.54 % (plain furosemide) to 69.12% (solid dispersion) in the first 60 min. Improvement in dissolution efficiency was found to be retained after stability studies. Capsules were filled with the formulation of solid dispersion using two different grades of lactose-α lactose monohydrate and anhydrous lactose and were found stable after stabilization studies.

Conclusion: The dissolution improvement of furosemide was attributed to its molecular dispersion in the novel carrier selected for this study. The recrystallization of furosemide was prevented due to intermolecular interaction between the novel carrier and furosemide. This was confirmed by FTIR. Evaluation of the dissolution data of factorial batches was analyzed by ANOVA. Analysis of the data revealed that selected levels of α lactose monohydrate and anhydrous lactose would be useful to navigate design space.
