Published: November 2021

Awareness of rights and obligations as a consumer became one of the problems faced by consumers. One way to increase consumer awareness is to provide access to consumer education through media used by consumers. This article aimed to identify and analyze the effect of socio-demographic characteristics and consumer education media toward consumer empowerment on public transportation. This research used a cross-sectional study through an online survey of 100 users of public transportation. Data were analyzed using multiple regression analysis. The results showed that the consumer empowerment index is 44.56 and categorized as capable level. Also, female, early-aged adults (18 - 40 years), high education, employee, income range from IDR 2 000 000 to IDR 3 000 000 per capita per month, and an urban area were the most empowered consumers. In addition, employment status and media of consumer education positively and significantly influenced consumer empowerment.
Do Domestic Investors with the Smallest Trading Orders Use Momentum Strategies in The IDX?
Authors: Syamni Ghazali , Wardhiah  , Musnad Said , Madjid M. Shabri Abd
Published: November 2021

This study aims to examine the use of the momentum strategy of domestic investors who trade small order sizes on IDX. The data used in this study is intraday trade transaction data from the LQ 45 Index for March, April and May 2017 obtained from The Indonesia Capital Market Institute. The method of data analysis used is the market-adjusted model approach. The results of this study indicate that domestic investors who trade in small order sizes tend to use the momentum strategy in government and non-government stock issuers. This finding implies that when IDX is in a good performance, investors should take advantage of this condition because buying stocks that have already been performing well provides a significant short-term abnormal return.

Published: November 2021

Illegal mining and inappropriate use of agrochemicals have exacerbated surface water pollution in Ghana. The quality of water has changed, and knowledge of their current condition is important for formulating policies to conserve the country's water bodies. This study assessed the quality of surface waters in Ghana's Pra River Basin. A survey of 344 local farmers randomly sampled was conducted and a physicochemical analysis of 33 water samples collected from 25 rivers in the basin. Boreholes are the main source of drinking water for 85% of farmers, and they assessed water quality by its appearance. Rainwater provides over 50% of the water needed by the respondents for domestic use. River water was mainly used for crop production and only secondarily for domestic use. At more than 80% of the sampled sites, pH, Fe and P were above the WHO recommended values, while Pb was exceeded at 30% of the sites. Cu, Hg, As and Fe were above permissible levels for irrigation, especially near the mining areas. The poor quality of river water makes it unusable despite its availability. A more effective and efficient land-use policy focusing on buffer zone protection is recommended to minimise water quality degradation in the basin.

Published: November 2021

Çocuklara okuma alışkanlığı ve edebiyat sevgisi kazandırmak için öğretmenlere ve aile üyelerine önemli görevler düşmektedir. Bu görevlerden bir tanesi de çocuklara uygun kitap seçimi yapabilmektir. Metnin, okuyan tarafından kolay ya da zor anlaşılma düzeyini okunabilirlik belirler. Okunabilirlik, dille ilgili bir kavramdır ve metnin okuyucu tarafından anlaşılabilmesi olarak ifade edilmektedir. Bu sebeple okuma sürecinde okurun düzeyine uygun okuma materyalleriyle buluşması önemlidir. Bu çalışmada da 3. sınıf düzeyindeki bir hikâye setinde bulunan beş hikâyenin okunabilirlik düzeyine bakılmıştır. Çalışmada betimsel nitelikte bir tarama yöntemi kullanılmıştır. Çalışmanın veri kaynağını, Ayşenur ÇAMALTI tarafından yazılan “Matematik Korsanları” adlı beş adet hikâye kitabı oluşturmuştur. Metinlerin analizinde Ateşman’ın Türkçe’ye uyarladığı “Okunabilirlik Formülü” ve Bezirci-Yılmaz’ın “Yeni Okunabilirlik Değeri” adlı formülü kullanılmıştır. Araştırma sonucunda; Bezirci-Yılmaz’ın formülüne göre, beş hikâyenin kolay düzeyde ve üçünün 2. ve 3.sınıf öğrencilere, ikisinin de 3. ve 4. sınıf öğrencilere hitap ettiği sonucuna ulaşılmıştır. Ateşman’ın okunabilirlik formülüne göre ise, dört hikâyenin kolay, bir hikâyenin orta güçlükte olduğu sonucuna ulaşılmıştır. Hikâyenin kolay olması ilkokul 3. sınıf öğrencilerine okuma kolaylığı sağlayacak; orta güçlükte olması ise öğrencileri okuma da zorlayacaktır. Türkçe okunabilirlik formülü ile ilgili olarak, harf sayılarının veya hece uzunluklarının dikkate alınacağı bir çalışma yapılabilir. Metinlerin okunabilirlik düzeylerinin belirlenmesinin yanında, okuduğunu anlama konusunda, öğrencilerin bireysel farklılıkları da dikkate alınmalıdır.
Editorial note
Authors: Davids M Razeen
Published: November 2021

Now that we have successfully migrated to our new online platform, AJN has taken the additional step of adopting a “publish-as-you-go” strategy. Articles will be published once they have been accepted and there will no longer be the usual wait until the next issue is published. New articles will be added throughout the year and will therefore be available to be read and cited much sooner. The latest articles which we are now publishing include a short review by Halperin on the assessment of the renal response in patients with potassium disorders. Halperin first gave us the well-known transtubular K+ gradient (TTKG) but in recent years has been recommending the use of the urine K+/creatinine ratio instead. In this article he explains the reasons for this change. Kapembwa et al. present their data on technique survival in patients on peritoneal dialysis (PD) at Tygerberg Hospital in Cape Town. Successfully maintaining patients on PD is especially important when a PD-first policy is being followed, as is the case at their centre. The issue of the access of rural patients with chronic kidney disease to healthcare is the topic of the paper by Singh et al., who report on referral patterns at a tertiary centre in Durban, South Africa. The paper by Camara et al., from the Free State province, South Africa, describes the outcomes of patients with acute kidney injury who needed continuous renal replacement therapy. In their cohort, patients with HIV infection were substantially younger and had a much worse outcome. Finally, the report by Makhoba et al. describes a case of osseous metaplasia in a renal allograft.
Assessing the renal response in patients with potassium disorders: a shift in emphasis from the TTKG to the urine K+/creatinine ratio
Authors: Halperin Mitchell L.
Published: November 2021

This article briefly reviews the reasons for replacing the transtubular K+ gradient (TTKG) with the urine K+/creatinine ratio, as a tool for evaluating the response of the kidney in patients with potassium disorders. An appreciation of the magnitude and importance of the intrarenal recycling of urea led to the realization that a large amount of urea is reabsorbed daily in the terminal collecting duct and that this renders invalid the assumption, used by the TTKG, that there is minimal solute reabsorption downstream of the cortical collecting duct (CCD). The urine-to-plasma osmolality ratio can therefore not be used to calculate the volume of fluid exiting the CCD nor the concentration of K+ in the luminal fluid in this nephron segment. We now recommend the use of the K+/creatinine ratio in random urine samples to estimate the rate of K+ excretion. A ratio of less than 1.5 mmol K+/mmol creatinine would be expected if the kidney is responding appropriately to hypokalaemia from a non-renal cause, and a ratio greater than 20 mmol K+/mmol creatinine would be appropriate as the renal response to hyperkalaemia.
Focal segmental glomerulosclerosis: challenges in definitions, pathogenesis and management
Authors: Feehally John
Published: November 2021

Focal segmental glomerulosclerosis (FSGS) is a well-defined pattern of glomerular injury identifiable on renal biopsy using light microscopy. FSGS is not a single entity and much information is needed to make a proper evaluation in each subject with the condition to identify the cause, prognosticate, and inform treatment choices. Categories of information required include: clinical presentation, responsiveness to steroids, pathological subtype, genetic background, and evidence for other adaptive, viral, and toxic causes. Primary FSGS describes a cohort of conditions identified by exclusion of known contributory causes, but does not represent a single entity. Clinical manifestations and outcomes of FSGS vary widely; they include asymptomatic proteinuria, cases of spontaneous remission, steroid-sensitive nephrotic syndrome, and nephrotic syndrome resistant to immune modulating therapy progressing to end-stage renal disease with recurrence after transplantation. Although immune modulating therapy (based notably on corticosteroids and calcineurin inhibitors) are widely used in primary FSGS, robust evidence of their efficacy remains scant.
Osseus metaplasia in chronic renal allograft rejection
Authors: Makhoba Aubrey M. , du Toit-Prinsloo Lorraine
Published: November 2021

The formation of heterotopic bone tissue outside the skeleton, known as osseous metaplasia, is a well-known phenomenon, but only a handful of cases describe this in renal allografts. We report the case of a 26-year-old female who was admitted to hospital for repair of an arteriovenous fistula of the right arm. Following her demise, the incidental finding of osseous metaplasia in the allograft kidney was made at autopsy. The pathophysiology, histology and possible clinical significance of the lesion are described.
Evaluation of potential drug–drug interactions among patients with chronic kidney disease in northeastern Nigeria
Authors: Okoro Roland N.
Published: November 2021

Background: Potential drug–drug interactions (pDDIs) may not manifest clinically in patients who are treated with multiple pharmaceutical agents, but when they do they can produce adverse outcomes. In patients with chronic kidney disease (CKD), the frequent use of multiple agents to manage this condition and its complications puts these patients at increased risk for DDIs. We determined the prevalence of pDDIs in CKD patients in two Nigerian hospitals and investigated possible predictors of pDDIs. Methods: This cross-sectional study involved patients with CKD who attended the nephrology unit of the University of Maiduguri Teaching Hospital and the medical outpatients clinic of the State Specialist Hospital in Maiduguri, Nigeria. We collected prescriptions, clinical data and laboratory data from the medical files of patients seen between January 2013 and December 2017. Descriptive and inferential statistics were used to analyse the data. Results: The study included 201 patients. A total of 273 pDDIs were identified in 166 patients (83%). These pDDIs included 30 unique drug interactions, the most common being between ferrous sulphate and calcium carbonate (seen in 46% of patients with pDDIs), followed by lisinopril and furosemide (8%). The proportion of clinically significant interactions was only 2%. There was a positive association between pDDIs and the total number of drugs prescribed (P < 0.001).Conclusions: A high prevalence of pDDIs was documented among Nigerian patients with CKD. The bulk of the interactions were related to the co-prescription of ferrous sulphate and calcium carbonate. The total number of drugs prescribed was a significant predictor of pDDIs. We recommend routine screening of prescriptions of CKD patients for potential pDDIs.

For the first time, polymeric forms of the complexes N,N′-bis(salicylidene)ethylenediaminonickel(II) and N,N′-bis(3-methoxysalicylidene)ethylenediaminonickel(II) have been investigated as functional materials for the conducting channels of organic electrochemical transistors. The dependence of the electrical conductivity of the polymers on the electrolyte anion-doping level has been established. The polymer film conductivity versus gate voltage curve parameters have been shown to depend on the molecular structure of the complex and the nature of the electrolyte solvent.
A Book Industry in Transition: The Shortage of Books in Indonesia in the Late 1940s and 1950s’
Authors: Kortekaas Eline Sophie
Published: November 2021

This paper examines the book shortage crisis in Indonesia in the late 1940s and 1950s. After the Second World War, several Dutch colonial publishing houses decided to continue their businesses in Indonesia. During the second half of the 1940s there seemed to be an evergrowing demand for books in Indonesia, and by the end of 1949, several Dutch newspapers reported a so-called book crisis. A small booklet entitled De boekennood van modern Indonesië (Book Crisis of Modern Indonesia) (1949) seemed to be the herald of this alarming news. It was written by A.P. van Schieveen, who was a board member of the Vereniging van Indische Boekhandelaren, a society of Dutch book traders which had been established in 1926. In this booklet he emphasizes the importance of reading for Indonesia’s development, but also warns the Dutch publishing industry of the fact that the preferred second language seems to have become English. As a solution to support the continuing use of the Dutch language, he urged the Dutch publishing industry to distribute large quantities of Dutch books all over Indonesia. G. Ockeloen, the editor of Madjallah perdagangan buku di Indonesia/Maandblad voor de boekhandel in Indonesië (1949), responded to this matter. According to Ockeloen, Van Schieveen was stating the obvious, and he wrote that there was an even larger crisis going on, which was the shortage of books in Bahasa Indonesia.
Cooking Surface Temperatures, Steak Thickness, and Quality Grade Effects on Volatile Aroma Compounds
Authors: Kerth Chris R. , Berto Michael C. , Miller Rhonda K. , Savell Jeffrey W.
Published: November 2021

Volatile aroma compounds were evaluated in USDA Top Choice and Select beef top loin steaks cut 1.3 cm (THIN) or 3.8 cm (THICK) and cooked on a commercial flat top grill at 177°C (LOW) or 232°C (HIGH) grill surface temperature. Gas chromatography/mass spectrophotometry was used to evaluate volatile aroma compounds. USDA Select steaks had more 2-octene and less trimethyl pyrazine in (P < 0.05) THIN steaks than THICK steaks, whereas Choice was unaffected by steak thickness (P > 0.05). Benzene acetaldehyde was higher and 4-hydroxybenzoic acid was higher in Select LOW grill temperatures compared with Select HIGH grill temperatures, whereas 5-methyl-2-furan carboxaldehyde was only present in Choice HIGH grill temperatures (P < 0.05). Two acids, 3 alcohols, 1 aldehyde, 1 alkane, and 1 ketone volatile aroma compound were higher (P < 0.05) for LOW compared with HIGH. Conversely, 5 alcohols, 2 aldehydes, 2 alkanes, all 4 furans, 6 ketones, 4 pyrazines, along with 1H-indole, 2 pyrroles, 2 pyridines, and 1 benzene aroma compound were higher (P < 0.05) in HIGH compared with LOW. Additionally, 1 alcohol, 2 aldehydes, 1 ketone, 1 sulfur-containing, and 6 other volatile compounds were lower, whereas 1 acid, 1 alcohol, 1 aldehyde, 2 furans, 1 ketone, 3 pyrazines, 1 sulfur-containing, and 1 other volatile compound were higher in the THIN compared with THICK. Some aroma compounds such as 2-butanone, 4-methyl-2-pentanone, 1-ethyl-1H-pyrrole, 1-methyl-1H-pyrrole, and 2-methyl-pyridine were only present in THICK cooked HIGH (P < 0.05). Steak thickness and grill temperature are important factors to consider in the development of positive Maillard reaction products. Key findings are that high grill temperatures and/or thick steaks with longer grilling times are required for the development of key Maillard reaction products and many Maillard reaction products were only found in the most severe high-temperature, long-time grilling scenarios.

Authors:   Department of Biomedical Engineering, Lund University, Box 118, 22100 Lund, Sweden, Notermans T , Hammerman M , Eliasson P , Isaksson H
Published: November 2021

Ruptures to tendons are common and costly, and no clinical consensus exists on the appropriate treatment and rehabilitation regimen to promote their healing as well as full recovery of functionality. Although mechanobiology is known to play an important role in tendon regeneration, the understanding of how mechano-regulated processes affect tendon healing needs further clarification. Many small-animal studies, particularly in rats and mice, have characterized the progression of healing in terms of geometrical, structural, compositional, mechanical, and cellular properties. Some of the properties are also studied under different mechanical loading regimens. The focus of this review is to summarize and generalize the information in the literature regarding spatial and temporal differentiation of tendon properties during rodent tendon healing following full-tendon transection, as well as how this is affected by altered in vivo loading regimens.

Published: November 2021

Introduction. Development and widespread dissemination of information technologies, including the Internet, mobile communications, cloud computing, Big Data, the Internet of Things, digital twin, etc. are being proactively introduced into versatile production and business processes of the construction industry. Therefore, a graduate of a civil engineering university must master the fundamentals of the above-listed technologies and know how to use them in his/her practical activities. It’s particularly important for those specialities that deal with information technologies in civil engineering. However, a number of important areas of knowledge that serve as the basis for mobile communications, the Internet, and wireless technologies, are only taught at specialized universities and schools. Nevertheless, students of civil engineering universities need to understand the theoretical provisions and processes of information technologies. Materials and methods. Systematization, the benchmark method, theoretical generalization of data extracted from literary sources were applied. Results. The founding notions, needed to discuss digital technologies, encompass temporary signal notation, spectral characteristics, spectral bandwidth, time and frequency division, multiplexing, discrete sampling and quantization of a signal. It is impossible to successfully study and effectively use these advanced technologies without having understood these fundamental technologies. The author offers a simplified explanation of these notions and principal processes in terms of their application in the construction industry. Conclusions. The author addresses complicated issues of the theory of signals and their transmission over communication lines. He presents the three key ideas that serve as the basis for multiple advanced information technologies, including time and spectrum signal notation, time and frequency division, multiplexing, discrete sampling and quantization of a signal. The author’s ideas can be used to teach mobile technologies, the Internet, the Internet of Things, cloud and edge computing, digital twin, etc.
Energy-focused substantiation of the choice of an air conditioning system for an office and shopping building
Authors:   Moscow State University of Civil Engineering (National Research University) (MGSU), Frolova Anastasiya A. , Lukhmenev Pavel I. ,   LLC “Engineering Delo”
Published: November 2021

Introduction. The air conditioning system is the main consumer of electricity inside office and shopping buildings. The coo­ling needs arise inside such buildings all over the year due to high amounts of heat emitted by people and equipment (computers, office equipment, cash registers), solar radiation (the envelopes of the majority of these buildings have continuous glazed facades) and sources of artificial lighting. A conventional cooling system has a compressor and condensers. The most important step towards an optimized and low-energy cooling system is the abandonment of compressor and condensers; in addition, the cold extracted from the outdoor air, is used in the system. This cooling technique is called an atmospheric co­oling system. The climatic features of Russia allow for a large-scale application of the cooling technology that uses natural cold. However, for a start, a decision was made to focus on a central region of the Russian Federation, namely, Moscow, rather than any northern areas of the country. Materials and methods. The problem is solved by the calculation method applied to the case of a 35-storey office building in Moscow. Various outdoor temperature options were considered as the bases for a transition to an atmospheric cooling system. The co-authors also compare different installation options for dry coolers, which in turn affect the routing length of refrigeration circuits. The annual demand for cold is calculated for all analyzed options. Results. Some results are presented in the form of tables of annual energy consumption by different types of air cooling systems. Conclusions. The co-authors have found that the location of dry coolers strongly affects the power consumption by a co­oling system. Power consumption by cooling systems was analyzed, and it was found out that transition to machine refrigeration at the higher outdoor temperature of +8 °C is more efficient from the standpoint of energy efficiency than the same transition at +5 and 0 °C.

Published: November 2021

Introduction. Reservoirs are important elements of the water resources regulation system; they make a substantial contribution to regional economies. A multi-criterial approach to selection of the best locations for dams is proposed in the absence of exhaustive information on the quantitative assessment of individual criteria. Morphometric characteristics of retaining reservoirs are among the most important tools for analyzing water resources; they represent a quantitative study designated for the mathematical simulation of the most important characteristics of a reservoir and their linking to the indices and parameters that allow to find out the hydrological conditions. The purpose of the study is to select and rank the factors needed to determine the priority locations for the construction of hydraulic structures. Materials and methods. A critical analysis of the research works is carried out; the hydrological, geological, topographical aspects and land use factors are reasonably selected, which allow to propose a hierarchical decision-making model for prioritizing areas where hydraulic structures can be designed. Results. AHP-TOPSIS, a hybrid method of the multicriterial analysis, was used. A reasonable choice of parameters and other factors is necessary to make decisions needed to determine the best area that will accommodate construction works, since it will reduce the amount of pre-project work in a particular region. The reservoir, whose parameters and coefficients are studied, will be thoroughly explored with a focus on its hydrology, topography, geology, and terrain use. The municipality of Manicaragua, belonging to the province of Villa Clara, Cuba, is considered as a case of the practical application of this approach. Based on the information provided by the geographic information systems and the hybrid method of the multi-criterial analysis, a pairwise comparison of alternatives for each of the established parameters was performed, the weights of alternatives were obtained, and the order of prioritization of the areas that can accommodate hydraulic structures was established. Conclusions. The analysis of the priority areas, made on the basis of the selected parameters used as the criteria and alternatives, allowed us (1) to analyze 12,591 districts of the municipality of Manicaragua as the potential locations of hydraulic structures, and (2) to reduce their number to 23 %.

This study was motivated by the phenomenon of the emergence of various dhikr (remembrance) gatherings that bring together many people who experience spiritual aridity. In Aceh, currently, there is a dhikr gathering that is well known for its work for the community called Rateb Seuribee dhikr. Rateb Seuribee dhikr is one of the dhikr gatherings that is in great demand within the community. In this study, the aim is to delve deeper into Rateb Seuribee dhikr by focusing on the existence of Rateb Seuribee dhikr and character values. The study used descriptive qualitative methods to obtain accurate and reliable data. Data were collected by means of interview and observation. The participants of the study consisted of the leaders, administrators, and the members of Rateb Seuribee dhikr. The results of the study indicated that Rateb Seuribee dhikr appeared to respond to the current condition of society which is experiencing spiritual aridity due to being lulled by worldly desires, leading them to drift away from the Creator. Taking into account such situations, Sheikh H. Amran Waly Al-Khalidi established a dhikr gathering named Rateb Seuribee dhikr. The people are mostly interested in following Rateb Seuribee dhikr in order to get peace of mind, get closer to Allah, improve characters, develop social attitudes towards fellow community members, forge closer ties of friendship between fellow citizens, and increase religious knowledge. In addition, the character values ​​obtained in carrying out Rateb Seuribee dhikr include religious, honest, disciplined, patient, sincere, enthusiastic, respectful, communicative, social care, responsible, and care for the environment.

Memorizing the Qur'an is not an easy job. Parents need to be involved in guiding and motivating children to memorize the Qur'an at home, so that children's memorization be increases and strong. Sometimes, parents do not guide children back at home, only leave it to the teacher at school. So that children are less enthusiastic in memorizing the Qur'an. Thus the target of memorization that has been set has not been achieved. The purpose of this study is to determine the role of parents in children's memorization Qur'an education, the motivation of parents to send their children to memorization Qur'an education, and how parents motivate their children to take part in memorization Qur'an education at Integrated Islamic Elementary School Cendekia Darussalam. This type of research is qualitative research using field research methods. The research data were obtained through observation, interviews and documentation analysis techniques, then the data were analyzed using descriptive methods. The results obtained indicate that in the process of memorization Qur'an education for children, parents can act as mentors, managers, motivators and facilitators for children. The motivation of parents to send their children to memorization Qur'an education is so that children become memorizers of the Qur'an, parents get a crown in the hereafter, children who memorize Qur'an can be intermediary for parents to get a crown in Heaven, and add religious knowledge for children and parents. The way parents motivate their children to take part in memorization Qur'an education at Integrated Islamic Elementary School Cendekia Darussalam is to give praise, give gifts, give punishments, and tell stories, and call on children to love Allah and the Prophet. Based on the results of the study, it can be concluded that if parents do their roles well, children will be encourage, move and direct to memorize the Qur'an, so that learning destination are achieved.

Purpose. The aim of the work is to assess the role of the basic forces in formation of the dynamic structures of the upper layer in the Marmara Sea in different hydrological seasons. Methods and Results. The numerical model developed in Marine Hydrophysical Institute, Russian Academy of Sciences, was used to calculate the hydrodynamic and energy characteristics of the sea circulation. The horizontal spatial resolution was 1.22 × 0.83 km, 18 horizons were used vertically, and the time step was 0.5 min. The characteristics of the waters inflowing through the Bosporus and Dardanelles straits corresponded to the available observational data. On the sea surface, the daily average fields of tangential wind stress, heat fluxes, precipitation and evaporation for 2008 were preset; these parameters were calculated using the regional atmospheric model MM5. Spatial distributions of the vortex structures and the corresponding energy flows in the upper sea layer for different seasons were considered. Having been analyzed, the average seasonal spatial distributions of the current velocity fields and the components of the kinetic energy budget showed that during the year, the vortices in the upper sea layer were formed mainly by two mechanisms. In the central part of the sea, generation of a large-scale anticyclone and its seasonal variability are basically conditioned by the wind forcing, whereas formation and evolution of coastal cyclonic eddies are caused by the buoyancy force. In the fields where the buoyancy, pressure and friction forcing takes place, the zones of local extremes are distinguished. Two of them are the areas of water inflow through the Bosphorus and Dardanelles straits. The strongest variability is observed in the Bosporus region that is certainly conditioned by the fact that the inflowing Black Sea waters have a decisive influence on seasonal nature of the Marmara Sea circulation. The extreme values in the other zones are the result of the coastline structure heterogeneities, that leads to formation of the coastal eddies, the energy source for which is the available potential energy. Conclusions. Analysis of the results of the performed numerical experiment makes it possible to conclude that in the upper layer of the Marmara Sea, formation and variability of the central anticyclone are conditioned by the wind forcing, while those of the coastal cyclones – by the buoyancy effect.
Vortex Layer on the β-Plane in the Miles – Ribner Formulation. Pole on the Real Axis

Purpose. The problem of a non-zonal vortex layer on the β-plane in the Miles – Ribner formulation is considered. It is known that in the absence of the β-effect, the vortex layer has no neutral eigenmodes, and the available two ones (varicose and sinusoidal) are unstable. Initially, generalization of the problem to the β-plane concerned only the zonal case. The problem for a non-zonal vortex layer is examined for the first time in the paper. It is known that in the WKB approximation for the linear wave disturbances (regardless of whether a zonal or non-zonal background flow is considered), there is an adiabatic invariant in the form of the law of the enstrophy (vorticity) conservation. For the zonal vortex layer, the enstrophy conservation law also holds, and no vorticity exchange occurs between the waves and the flow in the zonal case. The non-zonal vortex layer has qualitatively different features; particularly, it does not retain enstrophy. Thus, as a result, there appears a new class of solutions which can be interpreted as pure radiation of the Rossby waves by a non-zonal flow. Generalizing the vortex layer problem on the β-plane to the non-zonal case constitutes the basic aim of the present study. Methods and Results. A new class of linear stationary wave solutions, namely the Rossby waves, is found. It is shown a non-zonal flow can be directed in one way, whereas the stationary wave disturbances can move in the opposite (contrary) direction. The coexistence of such solutions for the shear non-zonal flow and stationary wave disturbances takes place due to the influence of the external force and mathematically comes from a non-self-adjoining character of the linear operator for a non-zonal background flow. Conclusions. There exists a new class of solutions that can be interpreted as pure radiation of the Rossby waves by a non-zonal flow. There is no such solution for a zonal flow. It is just non-zoning that gives the effect of pure radiation and corresponds to the classical definition of radiation. This approach makes it possible to eliminate inconsistency in terminology, when instabilities are mistakenly called radiation, and radiation – pure radiation.
