We report the discovery of COOL J1241+2219, a strongly lensed galaxy at redshift z = 5.043 ± 0.002 with observed magnitude z

AB
 = 20.47, lensed by a moderate-mass galaxy cluster at z = 1.001 ± 0.001. COOL J1241+2219  is the brightest lensed galaxy currently known at optical and near-infrared wavelengths at z ≳ 5; it is ∼5 times brighter than the prior record-holder lensed galaxy, and several magnitudes brighter than the brightest unlensed galaxies known at these redshifts. It was discovered as part of COOL-LAMPS, a collaboration initiated to find strongly lensed systems in recent public optical imaging data. We characterize the lensed galaxy, as well as the central galaxy of the lensing cluster using ground-based grizJH imaging and optical spectroscopy. We report model-based magnitudes, and derive stellar masses, dust content, metallicity, and star-formation rates via stellar-population synthesis modeling. Our lens mass modeling, based on ground-based imaging, implies a median source magnification of ∼30, which puts the stellar mass and star-formation rate (in the youngest age bin, closest to the epoch of observation) at logM

We constrain a star-formation history for COOL J1241+2219  consistent with constant star formation across ∼1 Gyr of cosmic time, and that places this galaxy on the high-mass end of the star-forming main sequence. COOL J1241+2219  is two to four times more luminous than a galaxy with the characteristic UV luminosity at these redshifts. The UV continuum slope β = −2.2 ± 0.2 places this galaxy on the blue side of the observed distribution of galaxies at z = 5, although the lack of Lyα emission indicates dust sufficient to suppress this emission.
Dynamics of Sunspot Shock Waves in the Chromosphere and Transition Region
Authors: Kayshap Pradeep , Tripathi Durgesh , Jelínek P.
Published: January 2021

We study the dynamics of shock waves observed in the umbra of a sunspot using the spectroscopic observations from the Interface Region Imaging Spectrograph. The presence of a shock significantly deforms the shape of the spectral lines of Mg ii, C ii, and Si iv. We found that C ii 1335.71 Å and Si iv 1393.75 Å show double-peaked profiles that change to a single peak later on. However, the Mg ii h 2803.53 Å line first shows flat-top profiles that change into double peaks followed by the single peak. To study the shock dynamics, we isolate the shock component from the spectra by fitting two Gaussians. We find that the lifetime of the shock is largest in the Mg ii h 2803.53 Å line. Moreover, the plasma motion shows both the acceleration and deceleration phases of the shock. Yet, in C ii 1335.71 Å and Si iv 1393.75 Å, only the deceleration phase is observed. We observe a strong correlation between the largest blueshift of the shock and deceleration for all three spectral lines. We find a positive (negative) correlation between intensities contributed by the shocks in Mg ii and C ii (Si iv). This suggests that the shocks are first amplified in C ii, followed by a decline in the height range corresponding to Si iv. These results may indicate the dissipation of shocks above the formation height of C ii, and the shocks may have important roles in the dynamics of the upper chromosphere and transition region above sunspots.

Measurement of fluctuations in diffuse Hi 21 cm background radiation from the post-reionization epoch (z ≤ 6) is a promising avenue to probe the large-scale structure of the universe and understand the evolution of galaxies. We observe the European Large Area ISO Survey-North 1 (ELAIS-N1) field at 300–500 MHz using the upgraded Giant Meterwave Radio Telescope (uGMRT) and employ the “foreground avoidance” technique to estimate the Hi 21 cm power spectrum in the redshift range z = 1.96–3.58. Given the possible systematics that may remain in the data, we find the most stringent upper limits on the spherically averaged 21 cm power spectra at k ∼ 1.0 Mpc−1 are (58.87 mK)2, (61.49 mK)2, (60.89 mK)2, and (105.85 mK)2 at z = 1.96, 2.19, 2.62, and 3.58, respectively. We use this to constrain the product of neutral Hi mass density (ΩHI) and Hi bias (b
HI) to the underlying dark matter density field, [ΩHI
b
HI], as 0.09, 0.11, 0.12, and 0.24 at z = 1.96, 2.19, 2.62, and 3.58, respectively. To the best of our knowledge these are the first limits on the Hi 21 cm power spectra at the redshift range z = 1.96–3.58 and would play a significant role to constrain the models of galaxy formation and evolution.
Kepler-411 Differential Rotation from Three Transiting Planets
Authors: Araújo Alexandre , Valio Adriana
Published: January 2021

The differential rotation of the Sun is a crucial ingredient of the dynamo theory responsible for the generation of its magnetic field. Currently, the rotation profile of a star that hosts one or more transiting planet can be estimated. By detecting the same spot in a later transit, it is possible to infer the stellar rotation period at that latitude. In this work, we apply for the first time transit spot mapping to determine the differential rotation of Kepler-411, a K2V-type star with an average rotation period of 10.52 days, a radius of 0.79 R
⊙, and a mass of 0.83 M
⊙. Kepler-411 hosts at least four planets, the inner planet is a super-Earth with a radius of 1.88 R
⊕ and an orbital period of 3.0051 days, whereas the two larger transiting planets are mini Neptunes with radii of 3.27 and 3.31 R
⊕, and periods of 7.834435 and 58.0204 days, respectively. Their orbits are such that they transit the star at latitudes of −11°, −21°, and −49°. Analysis of the transit light curves of the three planets resulted in the detection of a total of 198 spots. For each transit latitude, the rotation period of the star was estimated and the differential rotation pattern estimated independently. Then a solar-like differential rotation profile was fit to the three rotation periods at the distinct latitudes, and the result agreed extremely well with the previous ones, resulting in a differential shear of 0.0500 ± 0.0006 rd day−1 or a relative differential rotation of 8.4% ± 0.1%.

Cet article examine, les facteurs explicatifs du risque d’échec entrepreneurial des PME camerounaises. Pour par venir aux résultats, nous avons effectué de prime abord une étude exploratoire auprès de huit PME des villes de Yaoundé et Douala. Cette étude exploratoire nous a permis de construire les variables contextuelles pour aboutir à un modèle d’analyse. Une enquête effectuée auprès de 152 PME camerounaises révèle que le risque d’échec de la plupart des PME provient des causes internes (notamment la mauvaise gestion financière, une main d’œuvre familiale pas toujours compétente) et des causes externes (à savoir : les non-paiements de créances, la concurrence déloyale, l’irrégularité dans l’approvisionnement en énergie électrique).

Didáctica para una nación católico-conservadora: los cuentos populares de Antonio Trueba
Authors: Pérez Núñez Javier
Published: January 2021

Informados por una estricta moral católica, por los fundamentos del conservadurismo social y por una concepción primordialista de la nación, los cuentos de Antonio Trueba eran muy del gusto de la burguesía moderada isabelina. Pero, por su ascendencia y pertenencia social, estaban escritos para entretener y atraer a las masas populares. Por eso su amplia difusión se debió a su lenguaje y argumentos, sencillos y de fácil comprensión, a su desarrollo en el ámbito local y al ruralismo costumbrista, que les acompaña. Con estos elementos Antonio Trueba imagina y enseña una nación virtuosa, vinculada al pueblo, pero ajena al principio de soberanía, que es la queremos aprehender y concretar en este artículo.

Uremia Coupled with Mucosal Damage Predisposes Mice with Kidney Disease to Systemic Infection by Commensal Candida albicans
Authors: Jawale Chetan V , Li De-Dong , Ramani Kritika , Lin Li , Li Kelvin , Methe Barbara , Biswas Partha Sarathi
Published: January 2021

Infections are the second major cause of mortality in patients with kidney disease and accompanying uremia. Both vascular access and non–access-related infections contribute equally to the infection-related deaths in patients with kidney disease. Dialysis is the most common cause of systemic infection by Candida albicans in these patients. C. albicans also reside in the gastrointestinal tract as a commensal fungus. However, the contribution of gut-derived C. albicans in non–access-related infections in kidney disease is unknown. Using a mouse model of kidney disease, we demonstrate that uremic animals showed increased gut barrier permeability, impaired mucosal defense, and dysbiosis. The disturbance in gut homeostasis is sufficient to drive the translocation of microbiota and intestinal pathogen Citrobacter rodentium to extraintestinal sites but not C. albicans. Interestingly, a majority of uremic animals showed fungal translocation only when the gut barrier integrity is disrupted. Our data demonstrate that uremia coupled with gut mucosal damage may aid in the translocation of C. albicans and cause systemic infection in kidney disease. Because most of the individuals with kidney disease suffer from some form of gut mucosal damage, these results have important implications in the risk stratification and control of non–access-related opportunistic fungal infections in these patients.
My story in response to the stories of my patients’ experience of the impact of the COVID-19 pandemic: a relational psychoanalytic approach
Authors: Knight Zelda Gillian
Published: January 2021

The hallmark of being human is to tell stories. The stories told give meaning to the experience, and it is in telling stories about our experience, that we begin the process of meaning-making. Psychotherapy is storytelling, and in our consultation room we, as psychotherapists, listen to the tales told. This paper documents my story in response to some of the stories of my patients’ experience of the impact of the unprecedented impact of the coronavirus disease 2019 (COVID-19) pandemic. While there have been pandemics before, this pandemic is arguable unique because of social media and the number of people across the world who can share their experience. It is said that more than 4 billion people have self-isolated at home together at the same time as a collective humanity in response to their country’s lockdown rules. For psychotherapists, the shift to online therapy has allowed for a continuation of psychotherapy, and the telling of stories of COVID-19. Some of their stories are sad stories of loss and uncertainty. Some of their stories are more positive and inspiring. In this paper, three patients’ stories have been selected that illustrate both the positive and negative reactions to the COVID-19 pandemic. As the conceptual framework is relational psychoanalytic with its focus on the dynamics of the intersubjective relationship, my story, as counter-transference reactions are incorporated.
Selective removal of specific anions using composite carbon electrodes coated with an anion-exchange resin powder
Authors: Son Ji-Won , Roh Hyun-Cheul , Choi Jae-Hwan
Published: January 2021

The selective removal of specific ions was explored by using a capacitive deionization (CDI) system with a selective composite carbon electrode (SCCE). An SCCE was manufactured by coating a carbon electrode with anion-exchange resin (AER) powders. The correlation between the characteristics of the AERs and ion selectivity was analyzed, and the ion selectivity of the SCCE was verified through CDI experiments with a mixed solution of chloride, nitrate, and sulfate ions. The adsorption equilibrium results of the AERs showed that the ion selectivity of an AER was greatly influenced by its ion-exchange capacity (IEC). The higher the IEC value was, the higher the selectivity for the divalent sulfate ion, whereas the smaller the IEC was, the higher the selectivity for the nitrate ion. The CDI experimental results show that the equivalent fraction of ions adsorbed to the SCCE was consistent with the result of the adsorption equilibrium test. Therefore, the ion selectivity of the SCCE was governed by the ion selectivity of the AER coated on the electrode surface. Notably, as the current density applied to the cell increased, the AER could not maintain an adsorption equilibrium state, which resulted in a decrease in the ion selectivity of the SCCE.

Published: January 2021

Background: Aortic knob enlarges in many cardiovascular disorders including hypertension. It can be easily evaluated in chest radiographs. The study was carried out to document and analyze measurements of aortic knob in normal and hypertensive population in chest radiograph.Methods: This descriptive cross-sectional study was performed in the Department of Radiology and Imaging, Tribhuvan University Teaching Hospital (TUTH) and Manmohan Cardiothoracic Vascular and Transplant Center (MCVTC) from July to October 2019. Postero-anterior (PA) chest radiographs of 200 individuals (100 normal and 100 hypertensives) between the age of 18 to 70 years were evaluated. Width of aortic knob (AKW), straight length of aortic knob (AKS), curved length of aortic knob (AKC) and aortic knob index (AKI) were measured. Aortic knob index (AKI) was determined from AKC divided by AKS.Results: The mean aortic knob index (AKI) for male and female were 1.24±0.06 and 1.20±0.07 respectively and the total mean aortic knob index (AKI) was 1.22±0.07 in normal population. In hypertensive population, aortic knob index (AKI) was 1.49±0.095 and 1.42±0.04 in male and female respectively. Total aortic knob index (AKI) for hypertensive population was 1.45±0.083. Aortic knob index in hypertensive population was significantly higher than that of normal population. Mean aortic knob index (AKI) in male was significantly higher than that in female in both normal and hypertensive population (p<0.05).Conclusion: Aortic knob index (AKI), the index for aortic diameter, was higher in hypertensive population and male. Thus, simple measurement of aortic knob in PA chest x-ray may help in predicting cardiovascular disorder.

Published: January 2021

Objective: This paper describes the development and feasibility evaluation of a formative remote objective structured clinical examination (OSCE) for second-year students in a four-year Bachelor of Pharmacy (B.Pharm.) honours programme.
Methods. A five- station remote formative OSCE was developed and implemented using Microsoft Teams. The authors used a post-OSCE evaluation, in combination with the results of a students’ survey and comprehensive feedback from faculty.
Results: A total of seventy second-year B.Pharm. (Hons.) students participated in the online OSCE. Based on the post-OSCE evaluation, about 80% of students agreed that the OSCE ran smoothly. Respondents agreement on the time allocated to complete each station varied between 63.6% and 81.8%. Time allocation for each station and internet connectivity were raised as the main concerns by both the students and the faculty.
Conclusion: A remote online OSCE is a feasible strategy for assessment of various skills based on different tasks, reflecting the scope of practice for future pharmacists, and offers a promising direction towards the assessment of such practical skills. Online OSCE planning, development and evaluation are in themselves useful for clarifying assessment goals, processes, hindrances, and affordances

AYURVEDIC MANAGEMENT OF MALE INFERTILITY DUE TO OLIGOSPERMIA AND VARICOCELE: A CASE STUDY
Authors: Jiji V  , Priyanka R  , Asha ST  , Asha Sreedhar
Published: January 2021

Infertility is defined as the failure of a couple to achieve conception after one year of regular sexual intercourse without any contraception. Male infertility can be defined as any health issue in a man that lowers his chance of impregnating a fertile female partner. Current data reveals that about one third of all infertility cases is due to male factor defect. Oligospermia is a condition of suboptimal concentration of spermatozoa in the ejaculated semen to cause successful fertilization of an ovum. Hence the management of this issue is of utmost importance in the current days. Ayurveda addresses the male factor defects under broad classification of Ashtavidhasukradushti in which oligospermia can be correlated to Ksheenasukra. A 33yr old male with 3 years of married life diagnosed with oligospermia, increased viscosity of semen and bilateral grade I varicocele and wife aged 26yrs with regular, ovulatory cycles and with apparently no reproductive issues, were treated according to Ayurvedic principles. After Deepana pachana with Pippalyasavam and Vicharana snehapana with Sukumara ghritha and Mahakalyanaka ghritha, repeated Virechana with Avipathi choornam was given. Kokilaksha Kashayam and Varanadi Kashayam was given internally. Bala thailam and Pinda thailam was advised for external application. Follow up showed improvement in Seminal parameters in terms of sperm concentration, viscosity and resulted in pregnancy. The present case signifies the importance of Ayurvedic treatment in bringing a positive outcome in the field of male infertility.
MANAGEMENT OF VICHARCHIKA (LICHEN SIMPLEX CHRONICUS) BY SHAMANA CHIKITSA: A CASE STUDY
Authors: Md Tanzil Ansari  , Sukumar Ghosh  , Jaya Kuila
Published: January 2021

In Ayurveda, most of the skin diseases are included under Kushtha. It can be classified into two groups which are Mahakushtha and Kshudrakushtha. Vicharchika is one among the Kshudrakushtha. According to classical texts, it can be characterised by Kandu (itching sensation), Shyava (blackish brown discolouration), Pidaka (eruptions), Bahusrava (excessive exudation), Raji (marked lining/lichenification), Atiruja (excessive pain) and Rukshata (dryness). Vicharchika can be correlated with Lichen Simplex Chronicus (LSC) based on its clinical presentation. LSC is a highly pruritic, circumscribed plaque or plaques of lichenified skin due to chronic scratching or rubbing. Vicharchika can be treated with Nidan parivarjana (Avoidance of etiological factors), Shodhana chikitsa (Purification therapy) and Shamana chikitsa (Palliative therapy). The present case study deals with a 45 years old male patient having complaints of severe itching in the palm of both hands associated with marked lining, dryness and thickened skin at the affected site for 5-6 months. This case is diagnosed as Vicharchika (Lichen Simplex Chronicus). For treatment Shamana chikitsa was administered for 1 month which showed good result.

Published: January 2021

Indonesia’s political system changed  after the amandment of the state’s constitution. As a consequence, significant changes in the system are inevitable, one of which is the paradigm of its governing body. The amended constitution states that all governing bodies are level, not placing its people’s consultative assembly at the highest position of the people sovereignty manifestation at the fullest. The changes in the state’s governing bodie’s position causes transposition of their tasks and authorities. The previous assembly’s authority, bestowed by the constitution, limits itself into not having regular authority except inaugurating selected president and vice president according to the statutes of the General Election Commission once in five years. Nevertheless, a further discussion may lead to a finding that, in practice, the assembly’s authority is substantively fundamental for Indonesia’s political life. It has the right of amending and ordaining the constitution, for example, which is crucial for the politic since 1945 State Constitution of the Republic of Indonesia is the highest of all laws and regulations.

Sosiologi Sebagai the Queen of Social Sciences: Sebuah Refleksi
Authors: Susilo Rachmad K. Dwi
Published: January 2021

Sosiolog adalah pekerjaan mulia, karena sosiolog adalah orang-orang yang mengetahui, memahami, dan menguasai relung masyarakat baik yang terlihat (manifest) maupun yang tidak terlihat (laten), baik sisi masyarakat yang terletak di permukaan maupun di bagian terdalam. Namun bila kita temukan di lapangan, sosiologi tampak masih belum berdaya. Tugas kenabian dan kekhalifahan yang melekat pada sosiolog sulit dibuktikan. Persentase keterlibatan ilmiah sebagian besar ditempati oleh ilmuwan sosial politik terapan. Padahal umur sosiologi cukup panjang: Ibnu Khaldun mengembangkan sosiologi pada abad ke-14; August Comte memberi nama Sosiologi pada abad ke-18; dan di Indonesia, jika dihitung dari Selo Soemardjan yang menyelesaikan studinya dari Amerika pada tahun 1959, umur sosiologi berusia 61 tahun. Sosiologi juga memiliki jargon yang menjadi klaimnya: ratu ilmu sosial. Namun pertanyaannya, apakah sosiologi benar-benar ratu? Walaupun sosiolog Indonesia sudah memiliki asosiasi baik ISI (Ikatan Sosiologi Indonesia) maupun APSSI (Asosiasi Program Studi Sosiologi Indonesia) yang sudah cukup aktif bekerja, kita kesulitan menemukan model sosiolog ideal dalam dunia profesional. Penulis menyadari bahwa universitas belum berhasil menghasilkan sosiolog yang benar-benar dapat bekerja tanpa atribut akademik. Melalui tulisan ini, penulis bermaksud untuk memahami dan menjelaskan dilema yang dihadapi oleh sosiologi dan sosiolog Indonesia serta usulan langkah untuk mengatasinya. Penulis memulai dari permasalahan mendasar yang kemudian dikaitkan dengan prinsip dasar dalam sosiologi.

The biometrics-based methods assume that the physical characteristics of an individual (as captured by a sensor) used for verification are sufficiently unique to distinguish one person from another. But the increase in twin births has created a requirement for biometric systems to accurately determine the identity of a person who has an identical twin. Identical twins have the closest genetics-based relationship and, therefore, the maximum similarity between fingerprints is expected to be found among identical twins. They can’t be discriminated based on DNA. As one of the most successful applications of image analysis and understanding, face recognition has recently received significant attention, especially during the past several years. Identical twin face recognition is a difficult task due to the existence of a high degree of correlation in overall facial appearance. In this paper, we study the usability of facial marks as biometric signatures to distinguish between identical twins. We propose a multi scale automatic facial mark detector based on a gradient-based operator known as the fast radial symmetry transform. The transform detects bright or dark regions with high radial symmetry at different scales. Next, the detections are tracked across scales to determine the prominence of facial marks. Extensive experiments are performed both on manually annotated and on automatically detected facial marks to evaluate the usefulness of facial marks as biometric signatures. The results of our analysis signify the usefulness of the distribution of facial marks as a biometric signature.

The paper outlines an application of smart solar “photovoltaic” power generation. Solar panels are typically in fixed position. They're limited in their energy-generating ability because they cannot consistently take full advantage of maximum sunlight. For more effective solar energy system, the solar panel should be able to align with sunlight as it changes during a given day. The present paper examines the design advantages of creating an intelligent solar tracking system like a helianthus flower using microcontroller based embedded system.

In most hospitals and clinics patient waiting times are continuously increasing due to a shortage of trained physicians. Wireless Doc is a device that integrates an Electrocardiogram (ECG), (EEG) and BP together for further medical examination. Wireless Doc aims at a faster and an efficient way for providing this information to assist a physician in acquiring an accurate diagnosis sooner thereby reducing patient wait times in emergency. The Electroencephalography (EEG) is used in the evaluation of brain disorders. Most commonly it is used to show the type and location of the activity in the brain during a seizure. It also is used to evaluate people who are having problems associated with brain function. The Electrocardiogram (ECG) aims to measure the cardiac rhythm and rate of a patient. It ensures that the QRS complex is intact for the diagnosis of cardiac arrhythmias. The ECG system is used to detect Respiratory Sinus Arrhythmia (RSA). Design considerations that need to be taken into account when designing an ECG, EEG and BP are discussed. By using the electrodes attached to the patient from which the electrical activity of the heart and brain are acquired, amplified, filtered and sent wirelessly through Zigbee networks to a base station for post processing.

Published: January 2021

The distortion and inter symbol interference caused by multipath effects of channel degrades the quality of signal transmission in transmission system of digital baseband. Adaptive channel equalization is used commonly to compensate these effects so as to increase the reliability of propagation. Recursive Least Squares (RLS) algorithm is most commonly used adaptive algorithm because of its simplicity and fast convergence. In this work, simulation model of finite impulse response adaptive equalizer based on RLS is developed to reduce distortion caused by channel. The constellation diagram before and after equalization is obtained. It is observed that bit error rate is decreased by fifty percent after equalization. Hence this shows that the algorithm appears to reduce channel effects effectively and achieves channel equalization.

Face detection is a image processing technology that determines the location and size of human faces in digital images or video. This module precedes face recognition systems that plays an important role in applications such as video surveillance, human computer interaction and so on. This proposed work focuses mainly on multiple face detection technique, taking into account the variations in digital images or video such as face pose, appearances and illumination. The work is based on skin color model in YCbCr and HSV color space. First stage of this proposed method is to develop a skin color model and then applying the skin color segmentation in order to specify all skin regions in an image. Secondly, a template matching is done to assure that the segmented image does not contain any non-facial part. This algorithm works to be robust and efficient.

Published: January 2021

In this paper, we present a Stationary Wavelet Transform (SWT) based method for the purpose of despeckling the Synthetic Aperture radar (SAR) images by applying a maximum a posteriori probability (MAP) condition to estimate the noise free wavelet coefficients. The solution of the MAP estimator is based on the assumption that the wavelet coefficients have a known distribution. Rayleigh distribution is used for modeling the speckle noise and Laplacian distribution for modeling the statistics of the noise free wavelet coefficients for the purpose of designing the MAP estimator. Rayleigh distribution is used for modeling the speckle noise since speckle noise can be well described by it. The parameters required for MAP estimator is determined by the technique used for parameter estimation after SWT. The experimental results show that the proposed despeckling algorithm efficiently removes speckle noise from the SAR images.

Anthropocene: a new frame of studies and its limits
Authors: Peliz Ana Carolina Lins
Published: January 2021

This article is a commentary on an article by Patrícia Vieira published in the current issue of Esboços: histórias em contextos globais, in which the author discusses the thesis that the idea of the annihilation of humanity could be read through the optic of a utopian perspective and not only from a dystopian view in the age of the Anthropocene. She uses the trilogy of the Canadian writer Margaret Atwood, MaddAddam, as an example of her central idea. The theoretical framework is structured around an interdisciplinary study of authors from political sciences, history, sociology and literature. This work is organized in two parts: the first summarizes the main ideas in Vieira’s article, and the second proposes a debate about the concept of Anthropocene, its limits and difficulties regarding human and social sciences.
Nomes of Lower Egypt in the early Fifth Dynasty
Authors: Khaled Mohamed Ismail
Published: January 2021

Abstract. Having control over the landscape played an important
role in the geography and economy of Egypt from the predynastic period
onwards. Especially from the beginning of the Old Kingdom, we have evidence
that kings created new places (funerary domains) called (centers) and
(Ezbah) for the equipment of the building projects of the royal tomb and
the funerary cult of the king, as well as to ensure the eternal life of both
kings and individuals. Kings used these localities in order to do so, and they
oftentimes expanded the border of an existing nome and created new
establishments. Consequently, these establishments were united or divided
into new nomes. The paper discusses the geography of Lower Egypt and the
associated royal domains in the early Fifth Dynasty based on the new
discoveries from the causeway of Sahura at Abusir.

Published: January 2021

The Jake Mandell Tone Deaf Test (JMT) is an online measure designed to evaluate pitch discrimination in the normal population. The test has been available online since 2006, but no psychometric data have been published. The present research was designed to provide validity and reliability data for this test. Study 1 was conducted in university students, and the performance on the JMT was compared to the AMUSIA online screening tests. Correlations were high with the subtests of the AMUSIA online screening tests, but especially with the Tone discrimination test. Study 2 was conducted in children, and the JMT was compared to different tests of musical abilities. The JMT showed a good relationship with the Tone Discrimination and Rhythm Imitation subtest, but especially with the global score of musical abilities. In addition, the test showed good one-year test-retest reliability. Finally, external validation of the JMT was obtained by noting that musicians obtained higher scores than non-musicians. Discussion is focused on the possibility of using the JMT as a rapid screening measure of individual differences in pitch discrimination in the normal population.
