Published: November 2022

Airway management in huge goiters present with challenges among anesthesiologists worldwide. Usually thyroid swelling presents with retrosternal extension, tracheal compression poses certain airway challenges. In our case there was no retrosternal extension or tracheal compression but tracheal deviation was present which make airway management difficult.

55yr old male pt, weight 60 kg, moderately built, came with chief complaints of gradually increasing swelling in front of neck since 3 years. He was k/c/o systemic hypertension on regular treatment taking tab. amlodipine 5mg OD. He was having no change in voice, no other systemic illness. He was evaluated for left sided huge goitre having neck swelling of size 14 cm × 15 cm × 10 cm. The mass was extending from lower jaw to below sternal notch, get below the swelling was possible. Xray neck AP and lateral view revealed tracheal deviation to right by the mass, this patient was posted for the hemithyroidectomy considering difficult airway plan of anaesthesia was awake fibreoptic intubation (under topical anaesthesia and sedation). In this case because of tracheal deviation to right the glottic structures were distorted, view to vocal cords was obscured by left arytenoid making the airway management difficult.

In general the difficulty of tracheal intubation in cases with thyroid disease is affected by compression or deviation of the trachea, the position and hardness of the tumour. Generally recommended techniques for securing airway in such patients are 1. Awake fiberoptic intubation 2. Awake direct laryngoscopy aided intubation 3. Inhalational induction.

Awake fibreoptic intubation using local anaesthesia - sedation technique is a suitable option in selected group of patients having possibility of airway obstruction.

Authors: Sharma Manoj , Kumar Gyanendra , Kamal Geeta
Published: November 2022

Lymphangiomas are congenital benign malformation of the lymphatic system, most commonly located in the head and neck region. The definitive treatment of lymphangiomas is surgery. Airway management in such patients is challenging in view of difficulty in visualizing the airway, difficult mask ventilation & intubation. The postoperative challenges include laryngospasm and airway obstruction due to airway edema caused by surgical manipulation. We report a case of massive lymphangioma of the neck in a 24-day old baby. Awareness of potential airway problems and possible complications is key to providing safe anesthesia to patients with lymphangioma.

The objectives of the study is to assess the limitations of the buyers rights to repair for the proposal of law enforcement proposals for respecting the balance of interests of the Parties under the Agreement; the elimination of the possibility of distorting civil law principles of conscientiousness and transparency. The tasks are permitted through the formal legal, regulatory, systemic, logical, comparative and theoretical and prognostic methods. According to the results of the work, the conclusions are formulated about the need to adjust the current legislation, including in the scope of manufacturers for the use of software that limits the repair of goods; unreasonably high degree of integration of blocks; failure to submit service documentation, as well as for electronic blocking of diagnostics, maintenance and repair of goods.
Legal regulation of the operation of oil and gas pipelines
Authors: Shuvatkina Yu. N.
Published: November 2022

The relevance of the chosen topic of the article is due to the lack of scientific research in the field of legal regulation of the operation of oil and gas pipelines. The article states that the legislation of the Russian Federation does not provide the concept of oil and gas pipelines. In the course of the study, the features of pipelines were identified and analyzed, which made it possible to give an appropriate legal definition of oil and gas pipelines. Also, the classification of pipelines was carried out in order to determine the place of oil and gas pipelines in the system of legal regulation. Taking into account the above pipelines classifications, an analysis of regulatory sources containing norms governing the operation of oil and gas fields was carried out, as a result of which their imperfection and insufficiency in relation to field and on-site pipelines was ascertained.

Published: November 2022

Drought and desertification have become global environmental problems, posing new obstacles to plant survival and adaptability. The main objective of this study was to evaluate the effect of drought stress on the morphological and physiological traits of Kochia prostrata. (L.) in greenhouse conditions. In the greenhouse experiment, drought stress was conducted in four levels of water regime treatment: 25, 50, 75, and 100 percent field capacity (FC). The experimental design consisted of a completely random design with three replications and 25 seeds per pot for every replication. In the greenhouse, seeds were planted in the soil using plastic containers. Then, 120 days of drought stress were administered, and morphological and physiological parameters were examined. The data were processed, and comparisons of means using the Duncan test (P0.05) were performed. Results demonstrated that when drought stress increased, the morphological and physiological features of K. prostrata decreased significantly. The highest plant dry weight was observed in drought stress of 25% FC and 100% FC with171.45 cm and 282.7 mg, respectively. The lowest rates of photosynthesis, stomatal conductance, transpiration, and mesophyll were observed in 25%FC stress treatments with 0.44 mmol m-1s-1, 0.070 mmol m-1s-1, 1.70 mmol-2s-1, 394.13 respectively. Plant length and Root dry weight are variables that decreased significantly with increasing drought stress. However, the decrease in the values of these variables was not significant at 50, 75, and 100%FClevels but was significant at the most severe drought level (25%FC). Based on the results of this study, it can be suggested that the K. prostrata species can be used in the sustainable development of ecological rehabilitation areas.

Published: November 2022

Purpose: To better understand clinic attendees ‘perceptions of nonsterile glove (NSG) use during vaccination and their concern for the environment. Design: This was a cross-sectional, self-administered, in-person survey. Methods: A non-random volunteer sample of vaccination clinic attendees ( n = 789) completed a survey assessing their perception of NSG use during influenza vaccination administration and their concern for the environment. Findings: Nearly all respondents equated NSG use with increased safety and professionalism. More than half of respondents reported feeling concerned about environmental waste associated with NSG use. Conclusions: NSG are not indicated for routine vaccination. Adherence to evidence-based practices on NSG use during vaccination can substantially reduce associated medical waste. Nurses can lead by example by only using NSG when indicated.

Published: November 2022

This study aimed to describe the impact of mutuality, anxiety, and depression on quality of life (QoL) in patients with heart failure (HF) using cross-sectional, convenient, and consecutive sampling. A total of 97 patients were recruited. Sociodemographic and clinical variables and self-report measures of anxiety, depression, mutuality, and QoL were collected. The results highlighted the pivotal role of mutuality (specifically the domain of shared values between patients and their caregivers) in determining perceptions of physical health. Conversely, depression was a negative determinant of perceptions of both physical and mental health. Future research is needed to describe in-depth and longitudinally the associations between mutuality and QoL in patients with HF.

As Duty Bearers, nurses are prime guardians, not only of the right to life (as stated in Article 3 of the United Nations Universal Declaration of Human Rights: “Everyone has the human right to life, liberty, and security”) but also the rights of women, the rights of children, and the rights of people in minority groups, among others. As Claim Holders, nurses have substantial claims towards labor rights, economic rights, maternity rights, and social protection rights, among others. This article presents systematic information about social determinants of health and explores nurses ‘inherent obligations in this domain, suggesting that nursing education must innovate, adding a human rights component to address the role of Promoters of Social Change.
Unconscious Bias and Its Impact on Public Health and Health-Care Systems
Authors: Abu-Bakr Abiola
Published: November 2022

The U.S. public health system has been challenged in constructive ways over the past year, from fighting a novel virus to managing the resulting pandemic, and surmounting pressure from the general public to reconcile past and present trauma fueled by health and racial inequities that claim lives and perpetuate physical, mental, and emotional harm in predominantly Black, Indigenous, and other non-white communities. Through term definitions, discussion of the current literature, and content expert opinions, this article reveals the casual yet calculated manner in which unconscious bias saturates health care and the governing public health systems in the United States, and presents a call to action for professionals in the public health field to keep racial and health equity at the forefront of solutions to the “wicked problems” faced in this field.

Published: November 2022

"Colletotrichum gloeosporioides", agente causal de la antracnosis, representa el principal patógeno postcosecha en papaya; por tal motivo, en el presente estudio se evaluó el efecto del trifloxystrobin en el control de la enfermedad en papaya cv. Maradol. El experimento comprendió tres etapas: pruebas de patogenicidad, pruebas de efectividad in vivo e in vitro. En las dos últimas se evaluaron los fungicidas trifloxystrobin y tiabendazol, este último como referencia comercial ademas un testigo absoluto fue utilizado. En la primera etapa se corroboró la patogenicidad del aislamiento de "C. gloeosporioides" en frutos de papaya, con 55% de incidencia para la inoculación por deposición y 94.4% para la inoculación por heridas. In vitro, trifloxystrobin obtuvo menor efectividad para el crecimiento micelial con 67% a 800 ppm; en cambio, el tiabendazol a 840 ppm alcanzó el 73.8%. El tiabendazol alcanzó el 60% de efectividad a 420 ppm, mientras que el trifloxistrobin lo obtuvo a 200 ppm. In vivo, trifloxistrobin controló la antracnosis en frutos de papaya cv. Maradol en un 47%. En contraste, tiabendazol fue el fungicida menos eficiente a la dosis recomendada para frutos en postcosecha, pues sólo alcanzó el 27.3%. Se concluye que el trifloxystrobin fue el fungicida con mejor control de la antracnosis.
TRENES DE TRATAMIENTO PARA AGUA DE LA INDUSTRIA PETROLERA
Authors: Lavariega Pulido Lourdes
Published: November 2022

La mayoría de los petróleos crudos que actualmente se extraen en todo el mundo, contienen agua y sales inorgánicas en cantidades apreciables (Martínez, 2006), los cuales deben ser removidos antes de su refinación. En México, PEMEX realiza la desalación y deshidratación del crudo mediante la separación del agua por campo eléctrico que debilita la barrera interfacial agua-aceite. En este proceso se genera un efluente de agua residual, llamado agua congénita. Su composición depende del tipo de petróleo que se extrae y procesa, crudo ligero o crudo Maya (pesado), así como de las técnicas de extracción: ascenso por bombeo o por inyección de gases, inundación con vapor, deshidratación con el uso de polímeros. Generalmente el agua congénita contiene sales inorgánicas en altas concentraciones e hidrocarburos. La disposición de este desecho es difícil por los peligros de salificación de los cuerpos receptores (agua o suelo) y por la presencia de compuestos tóxicos. Para prevenir impactos negativos al medio ambiente, se requiere de la implementación de sistemas de tratamiento con procesos avanzados de alto costo, tales como la desmineralización y la oxidación química.

Optical Ray Tracing Simulation by Using Monte Carlo Method for Reflectance-based Photoplethysmography Sensor in Human Skin and Fingertip Model
Authors: Misran Muhamad Affiq Bin , Bilgaiyan Anubha , Hattori Reiji
Published: November 2022

The pulse oximetry device has been used for decades to monitor human pulse rate and oxygen saturation. There are two types of pulse oximetry which are transmission and reflection based. However, most devices are unsuitable for daily health monitoring due to the bulkiness and inconvenience of long-term monitoring while continuously doing everyday activities. Therefore, developing a wearable device such as a patch would benefit the users. Several factors can be considered for such a system. One of them is the distance between the source and detector since both are the major components of this system. However, there is still a lack of information in this regard. This study used the ray-tracing Monte Carlo method to simulate transmittance and reflectance-based oximetry principles with a 663 nm wavelength as the light source. The results show the ray tracing behavior from the light source to the photodetector in the biological tissue under two different structures mentioned previously. The separation between the light source and the detector should be less than 3 mm for the reflection type. A significant difference was observed for a distance greater than 3 mm compared with the transmission-based, which has a higher photocurrent even at a 7 mm distance. However, this transmission-based device is limited to the placement of the device on the body part. It is due to the thickness, which varies depending on the body parts themselves. Therefore, wearable pulse oximetry devices with the reflectance-based principle are better due to higher signal acquisition than the transmittance-based, especially for the daily health monitoring system. Furthermore, it also can be used throughout any body part. This reflection-based device can fully utilize microfabrication to integrate the light source and photodetector.Keywords: PPG sensor, Monte Carlo, tissue optics, pulse oximetry, photoplethysmography.

QUENCHING BEHAVIOR OF THE SOLUTION FOR THE PROBLEMS WITH SEQUENTIAL CONCENTRATED SOURCES
Authors:   Ph.D., Professor, Department of Information Management, Tatung University, Taipei, Taiwan, China, Liu H T
Published: November 2022

This article studies the diffusion problems with a concentrated source which is provided at a sequential time steps in 1 dimensional space. The problems are considered for both Gaussian and fractional diffusion operators. For the fractional diffusion case, Riemann-Liouville operator with fractional order is used to describe the model with diffusion rate slower than normal time scale, which is known as sub diffusive problems. Due to this sub diffusive property, the existence and nonexistence behavior of the solution will be studied. Since the forcing term will experience a concentrated source at a sequence of time steps, the frequency, the time difference and strength of the source may affect the growth rate of the solution. Criteria for these effects which may cause for the quenching behavior of the solution will be given. The existence of the solution is investigated. The monotone behavior in spatial will be given. The quenching behavior of the solution will be studied. The location of the quenching point will be discussed.
A review of the bioaccumulation and adverse effects of PFAS in free-living organisms from contaminated sites nearby fluorochemical production plants
Authors: Parolini Marco , De Felice Beatrice , Rusconi Marianna , Morganti Michelangelo , Polesello Stefano , Valsecchi Sara
Published: November 2022

Per- and polyfluoroalkyl substances (PFAS) encompass a large, heterogeneous group of chemicals of potential concern to human and environmental health. Based on information for some legacy PFAS, such as perfluorooctane sulfonate and perfluorooctanoate, there is an increasing awareness that they can represent a serious environmental risk. Although the environmental occurrence and fate of some legacy PFAS and their toxicity under controlled laboratory conditions have been investigated, to date, there is a dearth of information on the exposure and potential adverse effects of these compounds towards free-living organisms. The present review summarizes the findings of field studies investigating the accumulation and adverse effects induced by the exposure to environmental mixtures of both legacy and emerging PFAS in the wildlife living nearby fluorochemical production plants (FCP). Biomonitoring campaigns performed close to FCP, which can be considered as hotspots of PFAS contamination, can be very useful in exploring the fate and toxicity of these compounds towards free-living organisms. All studies showed that the bioaccumulation of both legacy and emerging PFAS in wildlife living near the FCP is higher compared to control sites and other areas worldwide. However, the investigation on adverse effects returned contrasting results, suggesting the need for further studies to shed light on the toxicity and mechanism(s) of action of PFAS in free-living organisms.

Authors: AKKUŞ Berkant
Published: November 2022

Autonomous weapon systems are artificial intelligence-based, modern weapon systems that can identify and destroy targets without meaningful human intervention. In this article, human rights violations that may occur in case of widespread use of autonomous weapon systems in law enforcement operations in the near future will be examined and the positive obligations of states will be determined. States' positive human rights obligations in line with the United Nations, Basic Principles on the Use of Force and Firearms by Law Enforcement Officials, can be listed as weapon selection and the duty of precaution, the official training of law enforcement officers, procedural obligation, the right to explanation and the right not to be subject to completely automatic decisions. The research results of this article offer that, in line with the existing case law of human rights courts, autonomous weapon systems cannot comply with the positive obligation on the right to life.

Aspectos descriptivos imagenológicos del osteoma en los maxilares: revisión de la literatura
Authors:   , Angulo Diaz Carlos Manuel
Published: November 2022

El osteoma es una lesión osteogénica benigna, derivado de hueso compacto o esponjoso, se caracteriza por ser de crecimiento lento y aparece con más frecuencia entre los 20 y los 50 años de vida, con una prevalencia mayor en hombres con respecto a las mujeres. Clínicamente asintomáticos, los podemos encontrar en la región craneofacial, particularmente en los senos paranasales y la mandíbula, y pueden presentarse de tres formas: central, periférica y extraósea, siendo más comunes los solitarios a diferencia de los múltiples que están relacionados con el Síndrome de Gardner. El tratamiento de los osteomas es quirúrgico cuando causan complicaciones. Los estudios por imágenes como la radiografía panorámica y la TCHC, son las modalidades de mayor uso para determinar la ubicación, la extensión y las relaciones anatómicas de la lesión. Las características imagenológicas pueden presentarse como una excresencia ósea de hueso compacto, esponjoso o mixto. Por lo que el conocimiento de esta lesión nos permite poder tener mejores propuestas diagnosticas.

Sand Production in Two-Phase Gas-Water Flow

Published: November 2022

Sanding phenomenon is a severe problem in the oil and gas fields found in weak unconsolidated formations. While previous experimental researches mostly studied single-phase fluid flow, it rarely happened in real reservoirs. This study presents a novel approach to investigating sand production mechanism from multiphase fluid production through experiment of large specimen size, and a coupled Computation Fluid Dynamics – Discrete Element Method (CFD-DEM) modelling for two-phase flow. The sand production experiments on a weak artificial sandstone were conducted under one-phase and two-phase flow conditions: water flow in water-saturated and gas flow in water-saturated samples using a customized High-Pressure Consolidation System (HPCS). The coupled CFD-DEM numerical simulations of similar conditions were conducted to capture the salient features of sanding behaviour at micro-levels. The discontinuous nature of sand particles and the bonds between them were modelled using DEM, whereas the continuous fluid flow was described by CFD. The experimental results showed that more sand was produced by the two-phase flow of gas through an initially water-saturated sample as compared to the single-phase water flow. The numerical results on the other hand showed different internal void fraction distributions between the two cases, which led to a faster fluid outflow and a slightly higher sand production for the multiphase flow case. The experimental and numerical results were however limited by the experiment duration and the simulation time of an otherwise on-going sand production process.

This paper will present a case study of an Uncertainty Analysis recently performed for the Kashagan Field. This is the first full scale uncertainty work performed on the field since it came online in September 2016. The paper will describe unique challenges given Kashagan peculiarities and describe methods and approaches taken to address those.

A multi-scenario modeling workflow has been utilized to fully explore subsurface uncertainties in the decision space. First, uncertainties that were believed to have an impact on field performance based on the available data and learnings from previous studies were identified and ranked. Then, so-called categorical parameters were combined by grouping geologically relatable parameters into several scenarios with differentiating behaviors which were checked by performing screening simulation runs. This was followed by Design of Experiment (DoE) runs (Placket-Burman and Latin Hypercube), proxy modeling and Monte-Carlo analysis to aid selection of high, mid, and low models.

More than 400 simulation runs were generated resulting in a wide range of outcomes for key performance indicators, enabling the selection of high, mid, and low model realizations to evaluate future field development decisions. The approach of combining categorical parameters into multiple scenarios followed by DoE runs offered several advantages including full sampling of the uncertainty space and clearer link between geologic input and dynamic output. It also allowed to get maximum information using the lowest number of simulation runs. Communication techniques such as plumbing diagrams representing geologic scenarios were effective in discussion of study results amongst experts.
