 Hydraulic Fracturing (“Fracking”) and Rebirth of United States Chemical Industry by Bereslavsky EN* in Progress in Petrochemical Science_ International Journal of Petrochemical Science

 

Abstract

In the hydrodynamic formulation, the problem of liquid filtration from a channel filled with water through a soil layer with an underlying pressure horizon of relatively high permeability in the presence of evaporation from the free surface of groundwater is solved. When considering flows from channels, it is usually assumed [1-5]. that filtration occurs only through their bottom, which is usually taken as a horizontal segment. Taking into account the influence of the depth of water in the channels, that is, the study of movement not only through the bottom, but also through the slopes of the channels makes an additional angular special point in the physical area, which significantly complicates the solution of the problem. In this paper, the method developed earlier [6] is used to study the regime of ground water when filtering from such channels filled with water, in the presence of evaporation from a free surface.

Abstract

In the hydrodynamic formulation, the problem of liquid filtration from a channel filled with water through a soil layer with an underlying pressure horizon of relatively high permeability in the presence of evaporation from the free surface of groundwater is solved. When considering flows from channels, it is usually assumed [1-5]. that filtration occurs only through their bottom, which is usually taken as a horizontal segment. Taking into account the influence of the depth of water in the channels, that is, the study of movement not only through the bottom, but also through the slopes of the channels makes an additional angular special point in the physical area, which significantly complicates the solution of the problem. In this paper, the method developed earlier [6] is used to study the regime of ground water when filtering from such channels filled with water, in the presence of evaporation from a free surface.

In the framework of the theory of plane steady filtration of an incompressible fluid according to Darcy's law deals with the flow of rectangular channel of width 2l with water depth H in the soil capacity T, underlain by the well permeable pressurized horizon is relatively high permeability, the pressure of which is equal to H0 (0<H0<T), in the presence of a uniform intensity of evaporation ε (0<ε<1) with a free surface. To study the flow formulates a combined multi-parameter boundary problem of the theory of analytic functions which is solved using the method of Polubarinova Kochina PY [1-5], based on the application of the analytic theory of linear differential equations of Fuchs class [7] and the method of integrating such equations with four regular singularities [8-10], which is characteristic for problems of underground hydromechanics [11-15]. It should be noted that taking into account the specific features of the movements under consideration allows you to get solutions to problems in a closed form through elementary functions, which makes its use the most simple, convenient and effective

Unusual Intra-Operative Variable Plateau Capnogram Waveform in a Patient with Critical Unilateral Pulmonary Artery Stenosis: Case Report_ Crimson Publishers

 Unusual Intra-Operative Variable Plateau Capnogram Waveform in a Patient with Critical Unilateral Pulmonary Artery Stenosis: Case Report by Surendrasingh Chhabada* in Surgical Medicine Open Access Journal_ Surgical Medicine Open Access Journal

 

Abstract
Capnography is a simple non-invasive monitoring technique that provides prompt and valuable information about patient’s ventilation, perfusion and metabolism. We are presenting a case of a 10 year-old boy with a history of repaired Tetralogy of Fallot (TOF) undergoing a cardiac catheterization for recurrent left pulmonary artery (LPA) stenosis. A variable plateau capnogram waverform was detected and attributed to ventilation-perfusion abnormalities from differential lung perfusion secondary to critical LPA stenosis. Capnogram can prove vital monitoring tool in detecting critical perfusion abnormalities

Introduction
End tidal carbon dioxide (EtCO2) monitoring using capnography is a standard of care in anesthesia and essential for patient safety [1]. Intraoperative capnography provides information about CO2 production, pulmonary perfusion, alveolar ventilation and respiratory patterns. The different capnogram waveform shapes can reflect abnormalities that can be simple and common or can be a sign of imminent life-threatening complications [2,3]. Here we present a case of an unusual capnogram waveform that was detected during a diagnostic and therapeutic cardiac catheterization in a pediatric patient with history of Tetralogy of Fallot (TOF) repair with transannular patch and left pulmonary artery (LPA) patch.

Techniques to Reduce Blood Loss During Open Abdominal Myomectomy: Transverse or Vertical Incision?_ Crimson Publishers

 Techniques to Reduce Blood Loss During Open Abdominal Myomectomy: Transverse or Vertical Incision? by Ozlem Uzunlar* in Investigations in Gynecology Research & Womens Health_ Gynecology Open Access Journals

 

Abstract

Objective: To determine if there is a difference between uterine incision techniques (vertical vs transverse) in terms of clinical results.

Methods: All women with leiomyomas who underwent open abdominal myomectomy (n=61) between March and August 2016 in the Clinic of Gynecology and Obstetrics, Zekai Tahir Burak Women’s Health Care Training and Research Hospital were included and the clinical results were reviewed prospectively.

Result: The estimated blood loss during myomectomy increased in transverse group compared to vertical group (809, 33±483, 34ml vs 405, 32±180, 95ml, p<0.001). The median operative time is 60 minutes and the patients are discharged second day after surgery. No intergroup statistically differences are observed in surgical procedure.

Conclusion: Open abdominal myomectomy causes blood loss however, in transverse incision there is a higher level of estimated blood loss compared to vertical group

Vulnerability and Resilience of Tropical Coastal Ecosystems to Ocean Acidification_ Crimson Publishers

 Vulnerability and Resilience of Tropical Coastal Ecosystems to Ocean Acidification by Daniel M Alongi* in Examines in Marine Biology & Oceanography_ Journal of Marine Biology

 

Abstract

Ocean acidification leads to a wide variety of responses from tropical coastal ecosystems. Coral reefs are most vulnerable with most coral species exhibiting declining calcification rates with decreasing pH and carbonate chemistry parameters. Some corals show resilience to acidification likely due to active physiological regulation of their calcifying fluid. Other calcifying organisms, such as some foraminifera and coccolithophores, exhibit negative responses, whereas some symbiont-bearing calcifiers respond positively, to increasing acidification. Seagrasses and brown macroalgae thrive under acidified conditions, with increasing rates of primary productivity. Some tropical coastal fish species are resilient, and in some species, respond positively, to acidification. Some tropical species show complex, nonlinear responses to declining pH and carbonate chemistry. Factors that influence the ability of a species to adapt to and/or resist acidification include food supply, nutrient availability, temperature, diet, interactions with symbionts and other organisms and species and community diversity. Interactive effects of ocean acidification with other climate change parameters, such as elevated temperature, play an important but poorly understood role in determining the resilience and vulnerability of tropical coastal species, communities and ecosystems. Some short-lived species can undergo acclimation and/or adaptive evolution to increase fitness in the face of acidification. Biota living in tropical estuarine and nearshore environments, such as mangroves, seagrasses and intertidal and subtidal inshore benthos, are unlikely to be significantly affected by future acidification as such environments exhibit very wide variations in water and sediment pH and carbonate chemistry

Candida Parapsilosis Sensu Stricto Can Act as a Pathobiont in Conditions of Oral Dysbiosis_ Crimson Publishers

 Candida Parapsilosis Sensu Stricto Can Act as a Pathobiont in Conditions of Oral Dysbiosis by Rodríguez L* in Cohesive Journal of Microbiology & Infectious Disease_ Journal of Microbiology

 

Abstract
Recent publications have reported high prevalence of Candida parapsilosis Sensu Stricto in oral cavity niches. Our research group performed a pilot study in 2017 which showed that of the psilosis complex, Candida parapsilosis Sensu Stricto is the species most frequently isolated from oral cavity niches. Under inflammatory conditions, the probability of recovering it is almost four times higher, and it displays higher biofilm-forming capacity in-vitro, differing significantly from isolates of the same species obtained in conditions of eubiosis. This led us to hypothesize that an oral environment in dysbiosis overregulates virulent genes, promoting a more pathogenic phenotype. Accordingly, we decided to re-evaluate the in-vitro biofilm formation assay using a larger sample, under two nutritional conditions, using colorimetric methods for quantification. In addition, the results obtained were validated by imaging techniques. For both clinical conditions (eubiosis and dysbiosis), high biofilm forming phenotype predominated with both reading methods, and for both nutritional conditions tested. XTT showed significant difference between absorbance values for isolates from buccal dysbiosis and eubiosis (P=0.0025). Candida parapsilosis Sensu Stricto cells that colonize oral cavity niches are basically strong biofilm formers, regardless of in vitro growing conditions. However, the oral cavity in dysbiosis probably promotes virulence in this species due to inheritable epigenetic modifications

Interpersonal Relationships and Human Biofield_ Crimson Publishers

 Interpersonal Relationships and Human Biofield by Khaled Zahran S* in Psychology and Psychotherapy: Research Study_ Journal of Psychology

 

Abstract
Many factors stand behind interpersonal relationships, most of them experimentally and socially approved to be social and personal factors. Very few writes pointed at or discussed human bio-field or human chemistry as hidden factor(s) that may affect such relationships. This article is a primary trail that introduces such hypothesis through theoretical backgrounds

Interpersonal Relationships
Interpersonal relationship is a strong deep or close association between two or more people that may rang in duration from brief to enduring. There are many types of interpersonal relationships, as intimate relationships, as in romantic relationship generally. On the other hand, there are hate and pathological relationships, as abusive, codependent and narcissists. Social connections are essential for health and well-being. People who social needs go unmet have greater incidence of depression, weaker immune systems, and higher mortality rates compared to those with close connections [1]. There are mainly three reasons that drive human to establish relationship; need to belong, as Maslow’s hierarchy of needs, such as children’s attachment to their parents, second, social exchange, coast-benefit relationship, relation satisfaction based on: rewards, coasts and comparison level

Effects of Air Pollution on Reproductive Health_ Crimson Publishers

 Effects of Air Pollution on Reproductive Health by Yue Zhi Dong* in Perceptions in Reproductive Medicine_ Journal of Reproductive Health

 

Abstract
Air pollutant exposure is closely related to many diseases, and its health risks cannot be ignored. Many epidemiological and toxicological studies have confirmed the clear adverse effects of air pollutant exposure on cardiovascular and respiratory system health, while the effects on reproductive health are still inconclusive. This article mainly discusses the effects of air pollution on reproductive health

Opinion
With the development of epidemiology and basic research, it is confirmed that air pollutant exposure is closely related to many diseases, and its health risks cannot be ignored. Many epidemiological and toxicological studies have confirmed the clear adverse effects of air pollutant exposure on cardiovascular and respiratory system health, while the effects on reproductive health are still inconclusive. Air Pollution, reactive oxygen species damage, and genetic or epigenetics abnormalities may be responsible for some cases of male infertility. On the one hand, the occurrence of female infertility is related to the change of life style, the decline of ovarian reserve and egg quality caused by the later reproductive age of women, on the other hand, it is also related to the deterioration of living environment

The Role of Hba1c in Severity and Mortality Rate of ST Segment Elevation Myocardial Infarction for Hospitalized Libyan Non-Diabetic Patients_ Crimson Publishers

 The Role of Hba1c in Severity and Mortality Rate of ST Segment Elevation Myocardial Infarction for Hospitalized Libyan Non-Diabetic Patients by Altalhi KGH* in Significances of Bioengineering & Biosciences_ Journal of Bioscience and Bioengineering

 

Abstract

Background: The severity of coronary artery disease (CAD) is directly related to the quality of glucose control in diabetic patient. Additionally, diabetes is associated with increased mortality following acute myocardial infarction compared to general population.

Objectives: To evaluate the association of HbA1c level and severity of CAD, and outcome of non-diabetic patient with STEMI in our hospital.

Patients and methods: 60 consecutives non-diabetic patient with acute ST elevation myocardial infarction were treated with thrombolytic therapy included in the present prospective study. Blood glucose and HbA1c level of all patients were measured within 3 hours of admission. Patient were divided into 3 groups according to HbA1c level: with cut-off 6.5% as diagnostic criteria of diabetes mellitus according to (American diabetes association) group (1) 6.5%, group (2) 6.5 to 8.5%, group (3) 8.5% and above, in hospital. Mortality and morbidities of acute STEMI were compared between groups.

Result: The mean age was 63±15 year and mean body mass index was 26.6±6 kg/m², 24 patients (40%) had history of hypertension, 27 patients (45%) of dyslipidemia, 36 patients (60%) were smoker. We found 45 patients with HbA1c≤6.5%, 5 patients with HbA1c 6.5-8.5%, 10 patients with HbA1c≥8.5%. There was strong correlation between admission of HbA1c and admission glucose level (P<0.001). Infarct size as measured by peak creatinine kinase, was not correlated with HbA1c level.

Conclusion: HbA1c is an important risk marker in the absence of history of diabetes mellitus in patients with AMI. The optimal management in these patients may contribute in decrease hospital mortality

A Case Studies to Estimate the Shearing Characteristics of a Natural Cemented Gravel Soil Trough Large in situ Direct Shear Test Flexural Strength of Concrete_ Crimson Publishers

 A Case Studies to Estimate the Shearing Characteristics of a Natural Cemented Gravel Soil Trough Large in situ Direct Shear Test Flexural Strength of Concrete by Carlo G Ferretti* in Advancements in Civil Engineering & Technology_ Open Journal of Civil Engineering

 

Introduction
In project of applied geotechnical engineering it is necessary to know the shearing characteristics of the soil in place. In some cases, it is not possible to recover intact samples, maintaining their representative mechanical properties and analyzing them in the laboratory. It is, therefore, necessary to carry out tests in situ to determine the mechanical characteristics of soil that are essential to project design. This article reports a practical case study on alluvial sediments with a coarse gravel sandy texture. For its appropriate analysis a large in situ direct shear test has been designed and performed. This technique identified the presence of a weak soil cementation by natural calcite and its important effect on geotechnical soil failure behavior. Moreover, the test stated the unusual shear characteristics for a granular soil-structure of alluvial origin, and the proper cohesion and friction angle values (C=36.9 kPa; ϕ= 52°) to consider in the project

Erik Erikson on Negative Identity & Pseudospeciation- Extended and Particularized by Ta-Nehisi Coates_ Crimson Publishers

 Erik Erikson on Negative Identity & Pseudospeciation- Extended and Particularized by Ta-Nehisi Coates by Friedman LJ* in Archaeology & Anthropology: Open Access_ American Journal of Archaeology

 

Introduction

One can feel challenged in this chilling time when sundry variations of ultra-nationalism have become quite discernable in the USA, Europe, the Middle East, and parts of Africa. They have often taken the form of a rhetoric of fear and hatred toward “undesirables.” In this time of trouble in an increasingly nuclearized world, it is well to turn to Erik Erikson. His related concepts of “negative identity” and “pseudospeciation” need to be addressed more fully than they have in recent decades. Much is to be gained by both academic discussion and public debate over these two Erikson concepts. They signal elements in his “Way of Looking at Things.” More immediately, they help us address the crude and dangerous ultra-nationalisms of our time. Sensitive to the intimate relationship between the inner self and the outer social circumstances, Erikson, began in the mid and late 1940s to shape his most central concept - identity formation. It is well to refresh ourselves on the qualities he assigned to identity, for without that recall, one can hardly come to grips with his concepts of “universal Specieshood” and “pseudospeciation”, both of which emerged from it. In Childhood and Society [1], perhaps his most innovative book, Erikson displayed a marked cross-cultural perspective, comparing psychological development in several countries and cultures. While “officially” pledging fealty to Freudian psychoanalysis, Erikson was more attentive than Freud had been to ways the social circumstances of a society impacted the inner psyches of its members

Assessing Emotion Recognition in Adolescents After Traumatic Brain Injury: A Neuropsychological Cohort Study_ Crimson Publishers

 Assessing Emotion Recognition in Adolescents After Traumatic Brain Injury: A Neuropsychological Cohort Study by Brenda Hussey- Gardner* in Research in Pediatrics & Neonatology_ The Journal of Pediatrics

 

Introduction
A recent Saudi study [1] showed that TBI is the most common pediatric trauma and could be linked with harmful consequences. Deficits in the ability to evaluate emotional information are implicated in TBI. Researchers indicate that lasting emotion recognition deficits are common among adolescents who have suffered TBI [2]. Although adolescents who have TBI are generally discharged following rehabilitation hospitalization, some adolescents need additional rehabilitation interventions in the post-injury period, including outpatient services [3]. Studies showed that more than half of TBI adolescents are at risk of presenting with emotion recognition difficulties.

Preschoolers and elementary school students were mostly affected by TBI consequences in Saudi Arabia [1]. Survivors of adolescents TBI commonly result in emotional, behavioral and cognitive deficits [2]. However, emotion recognition deficits following TBI become obvious at age of adolescent hood and above [4]. Parents rate behavior disturbance and emotion changes as the most difficult and persistent problem following TBI. Emotion recognition requires the quick processing of motivations and emotional reactions of others. Essential emotional stimuli are conveyed by facial and eye expression [5]. Assessing adolescent’s abilities to understand emotion from facial expressions indicates that such skills are subject to developmental improvement mainly among adolescents with TBI

The Impact of Adjuvant Chemotherapy on Health-Related Quality of Life (HR-QoL), A Prospective Multicenter Measurement Study_ Crimson Publishers

The Impact of Adjuvant Chemotherapy on Health-Related Quality of Life (HR-QoL), A Prospective Multicenter Measurement Study by Antoine Abi Abboud* in Gastroenterology Medicine & Research_ Gastroenterology Open Access Journals

Introduction
Chemotherapy is one of the most commonly employed cancer treatments since its use provides a strong evidence for disease-free survival as well as overall survival for several cancer types. This type of treatment is associated with detrimental side effects that are difficult to tolerate and that impact the quality of life (QOL) of patients on different levels. As more patients undergo adjuvant chemotherapy, there has been a growing interest in investigating its impact on health-related quality of life (HRQOL). To our knowledge, most published literature focuses on HRQOL at specific time points during chemotherapy and only limited data describes the dynamics of HRQOL starting before treatment, during the complete duration and after completion of chemotherapy.

Objective: The objective of this study is to evaluate the impact of adjuvant chemotherapy on a patient’s quality of life before the start, half-way through, at the end and 3 months after the end of chemotherapy and to examine whether individual differences in quality of life among adjuvant chemotherapy patients could be accounted for by selected demographic and medical characteristics
