Published: February 2022

Abstract. The Measurements of Pollution in the Troposphere (MOPITT) satellite instrument has been measuring global tropospheric carbon monoxide (CO) since March 2000, providing the longest nearly continuous record of CO from space. During its long mission, the data processing algorithms have been updated to
improve the quality of CO retrievals and the sensitivity to the lower
troposphere. Currently, MOPITT retrievals are only performed for clear-sky
observations or over low clouds for ocean scenes. The cloud detection scheme was modified in the new V9 product, resulting in an improvement in
observational coverage, especially over land. Comparison of the spatial and
seasonal variations of the data coverage in V9 and V8 shows differences with significant geographical and temporal variability, with some regions such as
Canada and the Amazon exhibiting a doubling of data in winter. Here we
conducted an analysis of Moderate Resolution Imaging Spectroradiometer
(MODIS) cloud heights and cloud mask products along with MOPITT retrieval
cloud flag descriptors to understand the impact of cloud conditions on the
MOPITT observational coverage, with a particular focus on observations over
Canada. The MOPITT CO total column (TC) data were modified by turning off
the cloud detection scheme to allow for a CO retrieval result, regardless of
their cloud status. Analyses of the standard V8 CO TC product (cloud
filtered) and non-standard product (non-cloud-masked) were conducted for
selected days. Results showed some coherent structures that were observed
frequently in the non-masked CO product that was not present in the V8
product and could potentially be actual CO features. Many times, these CO
plumes were also seen in the Infrared Atmospheric Sounding Interferometer
(IASI) CO TC product. The MODIS cloud height analysis revealed that a
significant number of low-cloud CO retrievals were discarded in the V8
product. Most of the missed CO plumes in the V8 product are now detected in
the new V9 product as a result of the dependence of the MOPITT radiance ratio
(MRT) test over land. Comparisons of the MRT and MODIS cloud height data
indicate a remarkable negative correlation. As a result of the modified V9 cloud detection algorithm, a significant portion of the low-cloud CO retrievals is now incorporated in the new V9 MOPITT product. Consequently, the observational coverage over Canada is significantly improved, which benefits
analyses of regional CO variability, especially during extreme pollution
events. We also conducted a comparison of MOPITT and IASI CO TC and found
generally good agreement, with about a 5 %–10 % positive bias that is more pronounced in highly polluted scenes.
Distribution and characteristics of wastewater treatment plants within the global river network
Authors: Ehalt Macedo Heloisa , Lehner Bernhard , Nicell Jim , Grill Günther , Li Jing , Limtong Antonio , Shakya Ranish
Published: February 2022

Abstract. The main objective of wastewater treatment plants (WWTPs)
is to remove pathogens, nutrients, organics, and other pollutants from
wastewater. After these contaminants are partially or fully removed through
physical, biological, and/or chemical processes, the treated effluents are
discharged into receiving waterbodies. However, since WWTPs cannot remove
all contaminants, especially those of emerging concern, they inevitably
represent concentrated point sources of residual contaminant loads into
surface waters. To understand the severity and extent of the impact of
treated-wastewater discharges from such facilities into rivers and lakes, as
well as to identify opportunities of improved management, detailed
information about WWTPs is required, including (1) their explicit geospatial
locations to identify the waterbodies affected and (2) individual plant
characteristics such as the population served, flow rate of effluents, and level
of treatment of processed wastewater. These characteristics are especially
important for contaminant fate models that are designed to assess the
distribution of substances that are not typically included in environmental
monitoring programs. Although there are several regional datasets that
provide information on WWTP locations and characteristics, data are still
lacking at a global scale, especially in developing countries. Here we
introduce a spatially explicit global database, termed HydroWASTE, containing 58 502 WWTPs
and their characteristics. This database was developed by combining national
and regional datasets with auxiliary information to derive or complete
missing WWTP characteristics, including the number of people served. A
high-resolution river network with streamflow estimates was used to
georeference WWTP outfall locations and calculate each plant's dilution
factor (i.e., the ratio of the natural discharge of the receiving waterbody
to the WWTP effluent discharge). The utility of this information was
demonstrated in an assessment of the distribution of treated wastewater at
a global scale. Results show that 1 200 000 km of the global river
network receives wastewater input from upstream WWTPs, of which more than
90 000 km is downstream of WWTPs that offer only primary treatment.
Wastewater ratios originating from WWTPs exceed 10 % in over 72 000 km of
rivers, mostly in areas of high population densities in Europe, the USA, China,
India, and South Africa. In addition, 2533 plants show a dilution factor of
less than 10, which represents a common threshold for environmental concern.

Validation of a coupled atmospheric–aeroelastic model system for wind turbine power and load calculations
Authors: Krüger Sonja , Steinfeld Gerald , Kraft Martin , Lukassen Laura J.
Published: February 2022

Abstract. The optimisation of the power output of wind turbines requires the consideration of various aspects including turbine design, wind farm layout and more. An improved understanding of the interaction of wind turbines with the atmospheric boundary layer is an essential prerequisite for such optimisations. With numerical simulations, a variety of different situations and turbine designs can be compared and evaluated. For such a detailed analysis, the output of an extensive number of turbine and flow parameters is of great importance. In this paper a coupling of the aeroelastic code FAST (fatigue, aerodynamics, structures, and turbulence) and the large-eddy simulation tool PALM (parallelised large-eddy simulation model) is presented. The advantage of the coupling of these models is that it enables the analysis of the turbine behaviour, among others turbine power, blade and tower loads, under different atmospheric conditions. The proposed coupling is tested with the generic National Renewable Energy Laboratory (NREL) 5 MW turbine and the operational eno114 3.5 MW turbine. Simulating the NREL 5 MW turbine allows for a first evaluation of our PALM–FAST coupling approach based on characteristics of the NREL turbine reported in the literature. The basic test of the coupling with the NREL 5 MW turbine shows that the power curve obtained is very close to the one when using FAST alone. Furthermore, a validation with free-field measurement data for the eno114 3.5 MW turbine for a site in northern Germany is performed. The results show a good agreement with the free-field measurement data. Additionally, our coupling offers an enormous reduction of the computing time in comparison to an actuator line model, in one of our cases by 89 %, and at the same time an extensive output of turbine data.
Being honest about lying: Defining the limits of auto/biographical writing
Authors: Brien Donna Lee
Published: February 2022

Debates about whether any writing is “true” and the relationship between literature and life have been current since Plato and Aristotle battled this out in The Republic and Poetics but, even in these days of postmodernist relativity, such discussion becomes most inflamed when talking about the so-called “literature of fact”, and especially regarding biography and autobiography, where writing the “true” story of a life is still the popular definition of these literary forms.
The Preface as Exegesis
Authors: Krauth Nigel
Published: February 2022

The delights in ‘explaining again’ about a creative work can be equal to the delights of actually writing it - a point Winterson only subtly admits to, but which Poe initiated, Greene embraced, Nabokov extemporised upon, and Barth is making a career out of. Exegetic activity provides opportunity for postgraduate writers to ‘speak twice’ about the literary nerves of their work, about the creative mechanisms driving it, and about the personal and cultural orientations that inform and frame and guide it. Current student exegetical activity reinvigorates the territory of the preface - a significant territory of information, perspective and debate.

Authors: Abdlhusein Mohammed A. , Al-harere Manal Naji
Published: February 2022

Let G be a finite, simple graph, without isolated vertices. For any non-negative integers x and y, a set D ⊆ V is a ”pitchfork dominating set pds”, when every vertex in D, dominates at most y and at least x vertices of V − D. A subset D−1 of V − D is an inverse pds if it is a pitchfork set. The pitchfork domination number of G, γpf (G), is the number of elements of a smallest pds. The ”inverse pitchfork domination number” of G, γ −1 pf (G), is the number of elements of a smallest inverse pds. In this paper, some modified pitchfork dominations and its inverse dominations are introduced when x = 1 and y = 2. Several bounds and properties are given and proved. Then, these modified dominations are applied on some standard graphs such as: path, cycle, wheel, complete, complete bipartite graph and their complements.

This paper aims to study scouring and the recommended countermeasures for Al Manshiya Bridge, which is located in the Blue Nile in Khartoum city. The bridge was constructed in the year 2006, but in 2015; the east embankment approach of the bridge was exposed to scour causing failure of the approach deck slab. The paper follows the general procedure outlined by the Federal Highway Administration (FHWA) for stream stability, evaluating scour at bridges and countermeasures in order to have hydraulically safe bridge. Geomorphic and hydraulic factors affect the stream were studied; a scour analysis was made using Hydrologic Engineering Center - River Analysis System (HEC-RAS) software. To account for long-term, contraction, and local scour potential for the Peak flow event, HEC RAS model was used to construct quasi- unsteady sediment model. In order to protect the bridge, countermeasures for the bridge east abutment and channel adjacent to the bridge are studied, riprap around abutment and spur dikes were considered as the most suitable countermeasures.

The importance of micro- and small enterprises in economic development has been acknowledged as a vital factor in the global economy. However, in spite of the dominance of micro and small enterprises in the industry, the stagnation of these small businesses has remained a source of contention in many countries. Access to finance is one important aspect in determining the growth motivation of micro-and small enterprise owners. Even though external finance may present a opportunity for expansion, it appears to have impeded the growth and upgrading of micro and small enterprises. The goal of this study is to determine whether the experiences in obtaining external financing had an impact on the growth motivation of the owners. A qualitative study was conducted to discover the factors that influence business owners' motivation to expand and upgrade the size of their business category. The study's findings has emerged the motivating drivers that influences the growth motivation of the owners. Based on the result of the study, access to finance rationalizes the stagnation and survival mentalities of micro and small business owners.

Published: February 2022

The sugarcane borer (Diatraea Saccharalis) is considered the main pest in the sugarcane crop due to the great damage it causes to the crop. Its permanence can portray significant losses in productivity and affect the quality of sugar and ethanol production. One of the methods used to manage the borer is through biological control through the insertion of the parasitoid Trichogramma Galloi. Mathematical modeling helps to understand biological control, as it allows us to carry out a qualitative analysis. In this article, we analyze a mathematical model, based on systems of ordinary differential equations, of the interaction between the sugarcane borer, which is represented by the egg and larval stages, and its parasitoid, which is considered in terms of parasitized eggs. In this model, we find equilibrium points and conditions for the stability of each one of them. Numerical simulations show a good approximation for stability.

Published: February 2022

The crack propagation on a spherical IMO Type B LNG tank deployed on a 150K class LNG carrier is studied. IMO Type B tanks require a high level of safety . Therefore, analyses such as strength evaluation, fatigue analysis, fatigue crack propagation analysis, and LNG leak rate should be conducted to ensure safety. Various fatigue crack growth models were proposed for fatigue crack propagation analysis. The Forman model and the Walker model consider the stress ratio. Furthermore, the Huang model, and the Lee and Kim model consider the stress ratio and the effects of overload and underload present in the past load history on crack propagation.To examine the effects of stress ratio and load history for the fatigue crack propagation models, the crack growth of the LNG tank was evaluated by considering the stresses under full load and ballast load operating conditions, and three stress amplitude sequence cases.

Published: February 2022

Recently, considerable research has been conducted to identify suitable replacement for aluminum material used in producing lightweight car bodies, and accordingly, various welding processes have been investigated. However, no research has been conducted to optimize joining processes through experimental comparisons of the various welding and fastening processes for the aluminum battery cases used in hybrid electric vehicle. Therefore, this study conducted a joint quality comparison of nine joining processes for the aluminum overlap welding for 1.2 mm thick Al5052-H32 material. The tested joining processes were self-piercing rivet(SPR), arc welding, refill friction stir spot welding(FSSW), laser welding, spot welding, adhesive bonding, clinching, hybrid joining, and flow drill screw(FDS). The test results were used to assess manufacturing based on OEM production guidelines for field production application. Each joining process was evaluated in terms of investment cost, joint strength, endurance, productivity, and weldability under different weight factors. The SPR was the most competitive process among the nine joining processes, and arc welding, refill FSSW, and laser welding were considered alternative choices for the joining process for aluminum-based battery case manufacturing. By contrast, adhesive bonding, resistance spot welding, hybrid welding, clinching, and FDS were determined to be challenging processes for use as primary processes.
Practice Research and Learning Resources
Authors: Mørck Line Lerche
Published: February 2022

In this article I describe Practice Research (PR) as a collective, contextualized project. First I will introduce 'PR as practice' by presenting the construction of 'Learning Resources in the community of Wild Learning' constructed among others by 'Wild Learning' and my self. Then I will discuss 'Practice research in theory and methodology' comprising three main features: First the relation between theory and practice is characterized as a joint venture. Second I stress that doing PR means not only having a joint venture with the professionals in a specific practice - it also means to analyze the specific practice from 'the outside', e.g. by relating it to how it is part of different participants' everyday life. I call this feature decentered analysis. The third important feature of PR is critical analysis; analyzing practice as both action contexts and discourse. Finally I present some critical reflections on the ideals, problems and dilemmas when working with PR.
Literature in Dialect: The Great Absentee
Authors: De Angelis Francesco
Published: February 2022

Prose production in dialect is probably the big absentee in Arabic literature textbooks. While poetry in dialect has managed to carve its own small space in textbooks on the history of Arabic literature, the same does not go for novels or short stories written in ‘āmmiyya. Most critics, especially Arabs, do not acknowledge their literary dignity. However, scholars of contemporary Arabic literature can no longer avoid seriously analysing Egyptian literature in ‘āmmiyya. In fact, in the course of the last two decades, the number of novels and short stories in Egyptian dialect has significantly increased. Furthermore, writing in dialect is increasingly widespread thanks to personal blogs and websites. In light of this emerging panorama in Arabic literature, the question is whether something is changing in relation to the acceptance of dialect as a literary language and if the time has come for literature in dialect to find its own place in literary textbooks.

The non-classical light resonance on the cesium D1 (894.6 nm) line has important applications in solid-state quantum information networks due to its unique advantages. The cesium D1 line has a simplified hyperfine structure and can be used to realize a light-atom interface. In our previous work, we demonstrated 2.8-dB quadrature squeezed vacuum light at cesium D1 line in an optical parametric oscillator(OPO) with a periodically poled KTP(PPKTP) crystal. However, the squeezing level is relatively low, and the tunability that has practical significance for squeezed light has not been further investigated. Theoretically, the increase of the transmittance of output mirror and the decrease of the intra-cavity loss of the OPO can improve the squeezing level. Here, we use super-polished and optimal coating cavity mirrors to improve the nonlinear process in OPO. We prepare 447.3 nm blue light from 894.6 nm fundamental light by a second harmonic generation cavity (SHG). The SHG is a two-mirror standing-wave cavity with a PPKTP crystal as the nonlinear medium. The power of generated blue laser is 32 mW when the incident infrared power is 120 mW. Using the blue light to pump an OPO, we achieve quadrature squeezed vacuum light at cesium D1 line. The OPO is a two-mirror standing-wave cavity with a PPKTP crystal. The threshold of OPO is reduced to 28 mW. The squeezing level of generated quadrature squeezed vacuum light is increased to 3.3 dB when the pump power is 15 mW. Taking into account the overall detection efficiency, the actual squeezing reaches 5.5 dB. We inject a weak signal beam into the OPO cavity to act as an optical parametric amplifier (OPA), and test the tunability of squeezzed light. The blue light and the squeezed light are tuned by using a low-frequency triangular wave signal to scan the Ti: sapphire laser. Gradually increasing the amplitude of the scanning triangle wave signal, the generated bright squeezed light can be continuously tuned over a range around 80 MHz without losing the stability of the whole system. The generated squeezed light offers the possibility for the efficient coupling between the non-classical source and solid medium in the process of quantum interface.

This paper reviews evidence presented by A Randomized, Controlled trial called a Low glycaemic load diet is shown to be effective in treating acne vulgaris in Korean patients, both clinically and histologically, suggesting that dietary variables, such as dietary variables, such as glycaemic load, is involved in the pathophysiology of acne. According to this article, investigation has proposed that dietary, especially Glycaemic load, have a role in the evolution of Acne Vulgaris. The study's goal was to see how a low glycaemic load diet influenced acne vulgaris lesions clinically and histologically. In a ten-week dietary intervention research, Participants with varying degrees of acne were randomly assigned to either a low GI load diet or a control group diet cohort. The outcomes indicate that the glycaemic load was successfully reduced. In the low-GI cohort, the percentage of non-inflammatory and inflammatory acne vulgaris lesions reduced substantially. Histopathological findings indicate that the low glycaemic load group had small pilosebaceous glands, less redness, and lower levels of Sterol Binding Protein -1and Interleukin -1 in skin samples. Acne had improved after reducing the glycaemic amount of the diet for ten weeks.

A cataract is described as the opacification of the lens. A cataract is the clouding of the lens.  A cataract is also described as any opacification in the lens. Because of this, there's lower withinside the imaginative and prescient. Cataract surgical procedure is the maximum conventional surgery in evolved countries. Cataract  maximum not unusual place motive of blindness in growing countries. In the presence of suitable capsular aid, cataract surgical procedure with phacoemulsification with intraocular lens (IOL) insertion withinside the capsular bag is the gold standard. Cataract surgical treatment is one of the most customarily carried out surgical procedures withinside the globe. It's additionally one of the maximum historic. Improvements in intraocular lens alternative technology have followed breakthroughs in cataract surgical techniques.  Cataract surgical treatment is one of the best remedies in medicine. Cataract surgical operation has an extended record courting returned lots of years. Initially, the surgical procedure changed into done with crude running skills, resulting in a lack of a huge range of eyeballs. With the development of running tactics and devices throughout the mid-20th century, numerous intracapsular cataract extraction remedies have become used. From the second 1/2 of the 20th century, artificial intraocular lenses' advent and significant utilization caused the rediscovery and refinement of the extracapsular cataract extraction method. Modern cataract surgical procedure has stepped forward to refractive cataract surgical procedure, which lets the doctorate alter the final refractive results for every patient. Postoperative refractive mistakes have reduced dramatically due to advances in optical biometry and contemporary intraocular lens (IOL) calculation algorithms, but residual astigmatism is difficult for each surgeon and sufferer and might bring about symptomatic impaired visual performance.  Cataracts are not typically because of aging. The signs of cataracts range primarily based on the kind of cataracts and the patient's way of life and visible needs. In the industrialized global, cataract surgical procedure is accomplished while the advantage of putting off signs and symptoms overcomes the little dangers related to a modern-day surgical operation. After the surgical procedure, 85-ninety percent of sufferers have to see simply sufficient to conform with maximum riding necessities in maximum nations. Cataracts usually expand over time, resulting in innovative, imaginative, and prescient loss that cannot be corrected with glasses. Blurry imaginative and prescient, issue studying in low mild, night time imaginative and prescient impairment, glare and halos round lights, or even double imaginative and prescient are all symptoms to appear out for. Other symptoms and symptoms of cataracts in adults over fifty-five are common modifications in eyeglass prescriptions and the capacity to study without analyzing glasses.
Epistaxis: Pathophysiology and Its Management
Authors: Goswami Yuktam , Gaurkar Sagar
Published: February 2022

Epistaxis means bleeding from the nose and is the most common emergency complaint. It is reported in all groups of age. It may generally be spontaneous or be induced by either nose picking or trauma to the inner tissue lining of the nose.  It may also be benign and self-limiting, whereas some can recur time. Epistaxis is a minor problem and can be treated easily, but sometimes it can lead to a life-threatening hemorrhage. Environmental factors can affect the frequency of epistaxis. That is, it increases in the winters as compared to other seasons. It is because of decreased humidity during the winters, which ultimately leads to reduced humidification of the nose.

Based on origin, epistaxis can be of two types- Anterior epistaxis and Posterior epistaxis. Anterior epistaxis originates from the Kiesselbach plexus in the frontal part of the nose, whereas the posterior epistaxis originates from the Woodruff plexus lying in the posterior or superior nasal cavity. Various local and systemic factors can cause it. Local factors contributing to nose bleeding are either localized trauma (nose picking) or facial trauma, anatomical abnormalities, inflammatory causes, etc. Systemic conditions that increase epistaxis risk are high blood pressure, cardiovascular diseases, and vascular and bleeding disorders. Epistaxis can often be managed at home or by a primary care general physician. But in cases where it is recurrent, or the bleeding is non-stop, the patient should immediately go to the hospital and take proper treatment.
