Climate benchmarks and input parameters representing locations in 68 countries for a stochastic weather generator, CLIGEN
Authors: Fullhart Andrew T. , Nearing Mark A. , Armendariz Gerardo , Weltz Mark A.
Published: February 2021

Abstract. This dataset contains input parameters for 12 703 locations around
the world to parameterize a stochastic weather generator called CLIGEN. The
parameters are essentially monthly statistics relating to daily
precipitation, temperature, and solar radiation. The dataset is separated
into three sub-datasets differentiated by having monthly statistics
determined from 30-, 20-, and 10-year record lengths. Input
parameters related to precipitation were calculated primarily from the NOAA
GHCN-Daily network. The remaining input parameters were calculated from
various sources including global meteorological and land-surface models that
are informed by remote sensing and other methods. The new CLIGEN dataset
includes inputs for locations in the US, which were compared to a
selection of stations from an existing US CLIGEN dataset representing
2648 locations. This validation showed reasonable agreement between the two
datasets, with the majority of parameters showing less than 20 %
discrepancy relative to the existing dataset. For the three new datasets,
differentiated by the minimum record lengths used for calculations, the
validation showed only a small increase in discrepancy going towards shorter
record lengths, such that the average discrepancy for all parameters was
greater by 5 % for the 10-year dataset. The new CLIGEN dataset has the
potential to improve the spatial coverage of analysis for a variety of
CLIGEN applications and reduce the effort needed in preparing climate
inputs. The dataset is available at the National Agriculture Library Data

A new gas absorption optical depth parameterisation for RTTOV
v13
Authors: Hocking James , Vidot Jérôme , Brunel Pascal , Roquet Pascale , Silveira Bruna , Turner Emma , Lupu Cristina
Published: February 2021

Abstract. This paper describes a new gas optical depth parameterisation implemented in the most recent release, version 13, of the radiative transfer model RTTOV (Radiative Transfer for TOVS). RTTOV is a fast, one-dimensional radiative transfer model for simulating top-of-atmosphere visible, infrared and microwave radiances observed by downward-viewing space-borne passive sensors. A key component of the model is the fast parameterisation of absorption by the various gases in the atmosphere. The existing parameterisation in RTTOV has been extended over many years to allow for additional variable gases in RTTOV simulations and to account for solar radiation and better support geostationary sensors by extending the validity to higher zenith angles. However, there are limitations inherent in the current approach which make it difficult to develop it further, for example by adding new variable gases. We describe a new parameterisation that can be applied across the whole spectrum, allows for a wide range of zenith angles in support of solar radiation and geostationary sensors, and for which it will be easier to add new variable gases in support of user requirements. Comparisons against line-by-line radiative transfer simulations, and against observations in the ECMWF operational system yield promising results, suggesting that the new parameterisation generally compares well with the old one in terms of accuracy. Further validation is planned, including testing in operational numerical weather prediction data assimilation systems.
A dynamically based method for estimating the Atlantic overturning
circulation at 26° N from satellite altimetry
Authors: Sanchez-Franks Alejandra , Frajka-Williams Eleanor , Moat Ben I. , Smeed David A.
Published: February 2021

Abstract. The large-scale system of ocean currents that transport warm surface (1000 m) waters northward and return cooler waters southward is known as the Atlantic meridional overturning circulation (AMOC). Variations in the AMOC have significant repercussions for the climate system, hence there is a need for long term monitoring of AMOC fluctuations. Currently the longest record of continuous directly measured AMOC changes is from the RAPID-MOCHA-WBTS programme, initiated in 2004. The RAPID programme, and other mooring programmes, have revolutionised our understanding of large-scale circulation, however, by design they are constrained to measurements at a single latitude. High global coverage of surface ocean data from satellite altimetry is available since the launch of TOPEX/Poseidon satellite in 1992 and has been shown to provide reliable estimates of surface ocean transports on interannual time scales. Here we show that a direct calculation of ocean circulation from satellite altimetry compares well with transport estimates from the 26° N RAPID array on low frequency (18-month) time scales for the upper mid-ocean transport (UMO; r = 0.75), the Gulf Stream transport through the Florida Straits (r = 0.70), and the AMOC (r = 0.83). The vertical structure of the circulation is also investigated, and it is found that the first baroclinic mode accounts for 83 % of the interior geostrophic variability, while remaining variability is explained by the barotropic mode. Finally, the UMO and the AMOC are estimated from historical altimetry data (1993 to 2018) using a dynamically based method that incorporates the vertical structure of the flow. The effective implementation of satellite-based method for monitoring the AMOC at 26° N lays down the starting point for monitoring large-scale circulation at all latitudes.
Observational Study on the Variability of Mixed Layer Depth in the Bering
Sea and the Chukchi Sea in the Summer of 2019
Authors: Jiao Xiaohui , Zhang Jicai , Li Chunyan
Published: February 2021

Abstract. Based on the high-resolution CTD data from 58 stations in the Bering Sea and the Chukchi Sea in the summer of 2019, the mixed layer depth (MLD) was obtained according to the density difference threshold method. It was verified that the MLD could be estimated more accurately by using a criterion of 0.125 kg/m3 in this region. The MLD in the Bering Sea basin was larger than that in the Bering Sea shelf, and both of them were smaller than that in the Bering Sea slope. The MLD increased northward both in the Chukchi Sea shelf and the Chukchi Sea slope. The farther northward, the greater the difference between the MLD calculated from temperature (MLDt) and the MLD calculated from density (MLDd) was, and the more important the role of salinity was in determining the MLD. The larger MLD (refer to MLDd specifically) in the Bering Sea slope might be due to the enhancement of mixing caused by the Bering Slope Current (BSC) and eddies. The horizontal advection of the Bering Sea Anadyr Water and the Alaska Coastal Water in the Bering Sea shelf led to the shallower MLD in the central transition zone. The northward increase of the MLD in the Chukchi Sea might be related to the low-salinity seawater resulting from the melting of sea ice in summer. The spatial variation of MLD was more closely related to the surface momentum flux than the sea surface buoyancy flux, and the wave had little effect.
The relationship between education and learning and its consequences for dialogic pedagogy
Authors: Matusov Eugene
Published: February 2021

Education is often viewed as formalized learning. I argue that the relationship between education and formalized learning is more complex and profound. In this conceptual essay, I examine the relationship between education and learning. Specifically, I discuss the cases when learning is not education and education is not learning. I argue that learning becomes educational when the person, the learner themselves, appreciates their learning. When learning is not appreciated by the learner, it does not constitute that person’s education. Thus, education is an ephemeral subjective construct, prone to appear and disappear as the person’s attitude to their learning changes. Also, education can be non-learning-based when it involves insights – abrupt, discontinuous changes of the person’s subjectivity – which are not caused by and rooted in the person’s experiences. Like learning, for an insight to be educational, it has to be perceived and appreciated by the person. I argue that human life consists of the flow of learning and insight. Noticing learning and insight by the person involves discontinuity of the person’s subjectivity, participation in activities, and other people that is recognized by others and the person. I discuss diverse forms of the person’s appreciation of learning and insights that constitute education. These forms vary from the behaviorist appreciation, as its lowest form, to the critical appreciation through critical dialogue as its highest form. Finally, I consider the consequences of defining education through a person’s appreciation of the transformation of their subjectivity for dialogic pedagogy.

Coautoría y revisión por pares: prácticas y percepciones de los investigadores noveles españoles
Authors: Rodríguez-Bravo Blanca , Nicholas David
Published: February 2021

El estudio analiza las opiniones y prácticas de los investigadores españoles noveles (Early Career Researchers o ECRs) respecto a la coautoría y a la revisión por pares según datos obtenidos de una encuesta. Se observa que los ECRs contribuyen a todas las tareas de una investigación aunque no siempre se les reconozca suficientemente el mérito. Desearían que el orden de firma estuviera regulado y reflejara el trabajo de cada autor. Asimismo, participan activamente en el proceso de arbitraje tanto en el papel de autores como en el de revisores. Abogan por mejoras en la revisión por pares pero se manifiestan medianamente satisfechos con un proceso que, aunque duro, resulta enriquecedor. Respecto a las alternativas son conservadores, prefieren estar protegidos por el anonimato y, consecuentemente, apoyan el modelo de doble ciego.

Seismic resistance of reinforced concrete-masonry shear walls with high steel percentages
Authors: Priestley M. J. N.
Published: February 2021

This paper summarizes test results of six heavily reinforced concrete masonry shear walls. The test programme was designed to investigate the necessity for the low ultimate shear stress specified by Masonry codes. Care was taken to accurately model good, but realistic design practice in detailing, and variables investigated in the series included steel percentage, influence of vertical load and confinement of potential crushing areas by mortar bed confining plates.

Results are presented which clearly indicate that the maximum current code allowance for ultimate shear stress is unreasonably low. No wall suffered diagonal shear failure despite maximum shear stresses exceeding four times the maximum code level. All walls displayed stable hysteresis loops at a displacement ductility factor of 2, and the less heavily reinforced walls (designed to approximately twice code levels) were satisfactory at  DF = 4. Degradation was never catastrophic and occurred due to slip of the entire wall along the foundation beam. Methods for reducing the degradation are discussed. Confining plates did not significantly reduce the degradation of the hysteresis loops, but substantially reduced damage to the walls  at high ductility factors.

Values of required ductility for walls designed to the Loadings Code are investigated, and on the basis of these and the experimental results, recommendations are made for relaxation to the ultimate shear provisions of the masonry code.

Dynamic tests on PTFE sliding layers under earthquake conditions
Authors: Tyler R. G.
Published: February 2021

The first part of a programme to assess the characteristics of PTFE sliding bearings during earthquake motions is described. Tests were performed on pure PTFE elements sliding on stainless steel. Representative normal loads were applied together with a sliding action, giving a maximum acceleration of 0.2 g and a maximum velocity of 38 cm/sec, i.e. motions equivalent to a moderate to severe earthquake.

At 0°C friction was found to have maximum coefficients which fell from 17 to 13% as the normal pressure was increased from 15 to 25 MN/m2. At 20°C corresponding values were reduced to 15 and 10%. Maximum friction generally occurred in the first cycle of loading after which values fell. After 5 cycles the range was typically 9 to 5%.

Tests on lubricated PTFE layers showed coefficients of friction less than 2% under the above test conditions; the maintenance of this low value over the years would depend on the effective retention of the grease.

It is possible that, by careful design of bearings for higher pressures, and utilizing filled PTFE materials, lower overall friction values for the dry condition may be achieved.
Multidirectional seismic response of a curved highway bridge model
Authors: Williams D. , Godden W. G.
Published: February 2021

A continuing experimental model study relating to the seismic resistance of large multi-span curved overcrossings is reported.

A brief description of the microconcrete model, a 1/30 true-scale version of a hypothetical prototype, which was tested on the 20 ft x 20 ft (6.1 m) Shaking Table at the University of California, is given. The response of the model is described for a series of simulated seismic excitations applied

(i) horizontally in the asymmetric longitudinal direction, and

(ii) horizontally in the symmetric direction, both alone and also with simultaneous vertical excitation.

The influence of expansion joint design on the seismic behaviour is the main parameter studied, with emphasis on the need for joint restrainers of adequate ductility, to effectively tie adjacent girders together. However, because of the severe damage caused by impacting at the expansion joints during moderately strong excitation, it is concluded that expansion joints should ideally be omitted from such structures.

The centre of earthquake loading on tall buildings
Authors: Irvine H. M.
Published: February 2021

A response spectrum technique is applied to two well known linear elastic continuous models of slender high rise buildings in order to obtain likely positions for the centres of earthquake loading. The models chosen are the uniform cantilever shear beam and the uniform cantilever shear wall, which represent the two extremes of pure shear deformation and pure flexural deformation, respectively. The results obtained are at variance with the static provisions of the current New Zealand code; this is especially so in the case of the shear wall. On the basis of these findings a tentative suggestion is made for a change to the familiar equivalent static lateral load distribution at present specified by the code.
The origins of "healthy architecture".
Health, hygiene and the quality of life in theory
and practice of pre-modern architecture –
an outline of research issues
Authors: Kwaśniewski Artur
Published: February 2021

The article presents the research issues related to the origins of healthy architecture – methodological assumptions, scope of the study, objectives, and main theses. The subject of study is the issue of human health, hygiene, and psychophysical well-being from the perspective of theory of pre-modern architecture, as well as the philosophical and medical basis of solutions proposed by architects and hygienists in the modern period (16th-19th centuries). The research is based on a critical analysis of source texts – such as architectural treatises, manuals of hygiene, and written statements concerning the rules of designing and using buildings. The author identifies the most relevant contexts, including the ancient and medieval traditions in architecture and medicine, the philosophy, culture, and customs of social elites, the level of knowledge about architecture, engineering, natural sciences, and medicine, building and urban code, and public health regulations. The article briefly discusses the evolution of views on health and disease prevention and the transformation of elements of the "health-promoting" architectural program of buildings.
Spatial arrangement of pre-war housing estates
in the context of sustainable development goals
on the example of the Księże Małe housing estate
in Wrocław
Authors: Gierko Aleksandra
Published: February 2021

The article aims to present the assumptions and a part of the chamber study results conducted on the Księże Małe estate in Wrocław. The starting point for the research was the observation that the pre-war German housing estates were planned in a functional way, with great care for the surroundings of the buildings, as well as with the use of solutions that would now be defined as elements of blue or green infrastructure. Thus, the pre-war spatial arrangement manner is in line with the contemporary postulates of sustainable development and "healthy" cities. However, the functions of green areas and their elements have degraded over time and nowadays it is often possible to read the former planning concept only by means of comparative cartographic studies. The results of the preliminary research confirm that the subsequent housing development transformations were of a degrading nature, and the pre-war character of the building surroundings is illegible for residents and readable in archival materials that have not been elaborated so far. Recalling the memory of the former arrangement method may contribute to project activities in the area of urban adaptation to climate change, and past practices, a model for shaping contemporary urban plans.
The health role of smart home bathroom
Authors: Jaglarz Anna
Published: February 2021

Social health awareness in the context of medical prophylaxis influences the current trends in the design of modern domestic bathrooms. The importance of the health role of the modern bathroom also results from the current social and economic situation around the world, resulting in the need for independent health control and the developing need for medical prophylaxis, taking care of immunity and psychophysical condition in the face of public health threats. Therefore, it was necessary to investigate the health factors in bathroom design based on research and analysis of literature and materials from foreign research institutes. The study concerned design possibilities in the selection of bathroom equipment elements enabling a wide range of comfort and supporting and monitoring the health of bathroom users. The research included a review and analysis of technologically advanced solutions, intelligent solutions, including Internet of Things (IoT) technologies, ensuring health prophylaxis in the home bathroom. The potential for the use of innovative technologies and the possibility of process control, easy flow of information in relation to the external environment (e.g. remote contact with a doctor) was indicated. The need for easy and intuitive use of intelligent devices was taken into account, as well as the possibility of independent, systematic control and protection of health without the need for stationary medical visits, with a view to time and safety of healthcare professionals and patients. The research results summarize the fields of medicine where smart bathroom appliances can create new opportunities to improve user health.
Designing taking into account the factor
reducing stress in the workplace
Authors: Krajewska Joanna
Published: February 2021

Workplace stress is a common cause of many diseases. It may be intensified by staying in one room for many hours and being exposed to unfavorable environmental stimuli. The role of designers may be important in shaping the work environment favorable to the mental comfort of building users.
The aim of the article is to review the solutions used in the architecture of public and commercial (office) buildings, as well as in interior designs and landscape projects, helpful to reduce the level of stress that may arise in the workplace.
The adopted research methodology includes the analysis of selected examples of design solutions, literature studies and the anthropological research carried out by the author using the structured interview method.
The result of the review is the collection of a rich set of design methods, which allow to shape the work environment favorable to the mental health of users of public and commercial buildings.
The conducted research allows to conclude that designers have a wide range of measures which enables to shape a work environment that is beneficial for mental health. The range of these possibilities in the hands of architects is constantly growing, and they should be constantly aware of it. In addition, listening to the needs of users of existing buildings may lead designers to new solutions.

Published: February 2021

Objective: This study investigated the association between feed efficiency, physicochemical properties, flavor precursors and biomolecules in the thigh meat of Korat (KR) chickens.Methods: The feed intake and body weight of individual male KR chickens were recorded from 1 to 10 weeks old to calculate the individual residual feed intake (RFI) of 75 birds. At 10 weeks of age, chickens with the 10 highest (HRFI) and lowest RFI (LRFI) were slaughtered to provide thigh meat samples. The physicochemical properties (ultimate pH, water holding capacity [WHC], drip loss) and flavor precursors (guanosine monophosphate, inosine monophosphate (IMP), adenosine monophosphate and inosine) were analyzed conventionally, and Fourier transform infrared spectroscopy was used to identify the composition of biomolecules (lipids, ester lipids, amide I, amide II, amide III, and carbohydrates) and the secondary structure of the proteins. A group t-test was used to determine significant differences between mean values and principal component analysis to classify thigh meat samples into LRFI and HRFI KR chickens.Results: The physicochemical properties of thigh meat samples from LRFI and HRFI KR chickens were not significantly different but the IMP content, ratios of lipid, lipid ester, protein (amide I, amide II) were significantly different (p<0.05). The correlation loading results showed that the LRFI group was correlated with high ratios of lipids, lipid esters, collagen content (amide III) and beta sheet protein (rg loading >0.5) while the HRFI group was positively correlated with protein (amide I, amide II), alpha helix protein, IMP content, carbohydrate, ultimate pH and WHC (rg loading >0.5).Conclusion: The thigh meat from chickens with different RFI differed in physiochemical properties affecting meat texture, and in the contents of flavor precursors and biomolecules affecting the nutritional value of meat. This information can help animal breeders to make genetic improvements by taking more account of traits related to RFI.

Published: February 2021

Objective: This study was conducted to investigate the potential effects of prolonged photoperiod on the serum lipids, carcass traits, and meat quality of Jinjiang cattle during winter.Methods: Thirty-four Jinjiang bulls aged between 14 and 16 months were randomly assigned to two groups that were alternatively subjected to either natural daylight +4 h supplemental light (long photoperiod, LP) or natural daylight (natural photoperiod, NP) for 96 days. The potential effects on the levels of serum lipids, carcass traits, meat quality, and genes regulating lipid metabolism in the intramuscular fat (IMF) of the cattle were evaluated.Results: Jinjiang cattle kept under LP showed significant increase in both dry matter intake and backfat thickness. the serum glucose and the plasma leptin levels were significantly reduced, while that of melatonin and insulin were observed to be increased. The crude fat contents of biceps femoris muscle and longissimus dorsi muscle were higher in LP than in NP group. In longissimus dorsi muscle, the proportions of C17:0 and C18:0 were significantly higher but that of the C16:1 was found to be significantly lower in LP group. The relative mRNA expressions in IMF of longissimus dorsi muscle, the lipid synthesis genes (proliferatoractivated receptor gamma, fatty acid-binding protein) and the fatty acid synthesis genes (acetyl-coa carboxylase, fatty acid synthetase, 1-acylglycerol-3-phosphate acyltransferase) were significantly up-regulated in LP group (p<0.05); whereas the hormone-sensitive lipase and stearoyl-CoA desaturase 1 were significantly down-regulated in LP than in NP group.Conclusion: Prolonged photoperiod significantly altered the growth performance, hormonal levels, gene expression and fat deposition in Jinjiang cattle. It suggested that the LP improved the fat deposition by regulating the levels of different hormones and genes related to lipid metabolism, thereby improving the fattening of Jinjiang cattle during winter.

Published: February 2021

Objective: With the rapid development of proteomics sequencing and RNA sequencing technology, multi-omics analysis has become a current research hotspot. Our previous study indicated that Xinjiang brown cattle have better meat quality than Kazakh cattle. In this study, Xinjiang brown cattle and Kazakh cattle were used as the research objects.Methods: Proteome sequencing and RNA sequencing technology were used to analyze the proteome and transcriptome of the longissimus dorsi muscle of the two breeds of adult steers (n = 3).Results: In this project, 22,677 transcripts and 1,874 proteins were identified through quantitative analysis of the transcriptome and proteome. By comparing the identified transcriptome and proteome, we found that 1,737 genes were identified at both the transcriptome and proteome levels. The results of the study revealed 12 differentially expressed genes and proteins: troponin I1, crystallin alpha B, cysteine, and glycine rich protein 3, phosphotriesterase-related, myosin-binding protein H, glutathione s-transferase mu 3, myosin light chain 3, nidogen 2, dihydropyrimidinase like 2, glutamate-oxaloacetic transaminase 1, receptor accessory protein 5, and aspartoacylase. We performed functional enrichment of these differentially expressed genes and proteins. The Kyoto encyclopedia of genes and genomes results showed that these differentially expressed genes and proteins are enriched in the fatty acid degradation and histidine metabolism signaling pathways. We performed parallel reaction monitoring (PRM) verification of the differentially expressed proteins, and the PRM results were consistent with the sequencing results.Conclusion: Our study provided and identified the differentially expressed genes and proteins. In addition, identifying functional genes and proteins with important breeding value will provide genetic resources and technical support for the breeding and industrialization of new genetically modified beef cattle breeds.
Nitrogen metabolism and mammary gland amino acid utilization in lactating dairy cows with different residual feed intake
Authors: Xie Yunyi , Miao Chao , Lu Yi , Sun Huizeng , Liu Jianxin
Published: February 2021

Objective: This study was conducted to enhance our understanding of nitrogen (N) metabolism and mammary amino acid (AA) utilization in lactating cows with divergent phenotypes of residual feed intake (RFI).Methods: Fifty-three multiparous mid-lactation Holstein dairy cows were selected for RFI measurements over a 50-d experimental period. The 26 cows with the most extreme RFI values were classified into the high RFI (n = 13) and low RFI (n = 13) groups, respectively, for analysis of N metabolism and AA utilization.Results: Compared with the high RFI cows, the low RFI animals had lower dry matter intake (p<0.01) with no difference observed in milk yield between the two groups (p> 0.10). However, higher ratios of milk yield to dry matter intake (p<0.01) were found in the low RFI cows than in the high RFI cows. The low RFI cows had significant greater ratios of milk protein to metabolizable protein (p = 0.02) and milk protein to crude protein intake than the high RFI cows (p = 0.01). The arterial concentration and mammary uptake of essential AA (p<0.10), branched-chain AA (p<0.10), and total AA (p<0.10) tended to be lower in the low RFI cows. Additionally, the low RFI cows tended to have a lower ratio of AA uptake to milk output for essential AA (p = 0.08), branched-chain AA (p = 0.07) and total AA (p = 0.09) than the high RFI cows.Conclusion: In summary, both utilization of metabolizable protein for milk protein and mammary AA utilization are more efficient in cows with lower RFI than in the high RFI cows. Our results provide new insight into the protein metabolic processes (related to N and AA) involved in feed efficiency.

Background: Extracorporeal shock wave lithotripsy (ESWL) is an effective and relatively safe method for crushing urinary tract stones Objectives: The purpose of this study was to compare the effect of running on treadmill and rope jumping exercises on the excretion of mass-like urinary stones following ESWL in the patients referred to the Asia clinic in the city of Ilam. Methods: This was a quasi-experimental study. The subjects were selected by the convenience sampling method and randomly divided into three groups, including control, treadmill running, and rope jumping (n = 50 per group). Data were collected by a questionnaire to record the sonographic characteristics of the stones before and after lithotripsy and analyzed by SPSS software version 24 using Chi-square, unpaired t-test, and one-way ANOVA at the significance level of 5%. Benieman-Hashberg method was used to correct multiple comparisons. Results: There was a significant difference in the number of excreted stones comparing the control, treadmill running, and rope jumping groups (F = 8.851, P = 0.002). There were significant differences between the control and both treadmill running (P = 0.038) and rope jumping (P = 0.002) groups regarding the rate of stone excretion. However, there was no significant difference between the treadmill running and rope jumping groups regarding the rate of stone excretion (P = 0.293). Conclusions: Rope jumping and treadmill running exercises can help to better and faster expel kidney stones, depending on their location, after lithotripsy.

Introduction: Nasal septal hematoma (NSH) is a complication of nasal trauma, which its emergency treatment is drainage of hematoma. Delayed treatment may result in necrosis of the nasal cartilage and saddle nose deformity. Case Presentation: Here, we reported a 15-year-old girl presented with NSH associated with a dental local anesthetic injection, which led to nasal septum necrosis. Conclusions: Computerized tomography (CT) scanning was performed to determine the hematoma size and existence of other complications.
MORFOLOGÍA, BIOMETRÍA Y TAXONOMÍA DE FORAMINÍFEROS PLANCTÓNICOS DEL DANIENSE BASAL: Palaeoglobigerina n. gen.
Authors: ARENILLAS Ignacio , ARZ José Antonio , NÁÑEZ Carolina
Published: February 2021

El Daniense basal contiene asociaciones oligotáxicas con foraminíferos planctónicos de pequeño tamaño (< 150 μm) y de morfología muy simple, derivadas de la radiación evolutiva acontecida tras el evento de extinción en masa del límite Cretácico/Paleógeno (K/Pg). Se ha revisado la clasificación taxonómica de este grupo de foraminíferos después de realizar análisis biométricos y morfológicos para delimitar las especies. Este estudio y la distribución bioestratigráfica de las especies están basados en material y muestreos de alta resolución de algunos de los cortes del límite K/Pg más continuos del mundo. Se propone Palaeoglobigerina n. gen. para incluir a pequeñas especies de globigerínidos trocoespiralados, de pared lisa microperforada y 3-4 cámaras en la última vuelta de espira, que aparecen en las Zonas de Guembelitria cretacea y de Parvularugoglobigerina eugubina (Daniense basal). Se han reconocido, descrito e ilustrado veintidós especies: cinco de Guembelitria, dos de Hedbergella, dos de Woodringina, dos de Chiloguembelina, cinco de Palaeoglobigerina n. gen. y seis de Parvularugoglobigerina.
Sella, A NEW NAME FOR THE GENUS Linaresia EL KADIRI, 1992 (NASSELLARIA, RADIOLARIA) PREOCCUPIED BY COPEPOD CRUSTACEANS (LAMIPPIDAE, MAXILLOPODA)
Authors: EL KADIRI Khalil
Published: February 2021

The aim of this short note is to create a new name of this genus since the original name Linaresia proved to pre-exist in the paleontological literature (Linaresia de Zulueta, 1908, Family Lamippidae, Copepod crustaceans, and Linaresia Gonzalez-Donoso, 1968, Family Gavelinellidae, Agglutinated Foraminifera). The new name created for the above mentioned radiolarians is: Sella. This name derives from an arbitrary combination of letters (International Code of Zoological Nomenclature). The type species of Sella is S. beniderkoulensis by original designation (El Kadiri, 1992).

Restos de Hippidion y Equus (Amerhippus) procedentes de las barrancas de San Lorenzo, Pleistoceno Tardío (provincia de Santa Fé, Argentina
Authors: Prado José Luis , Alberdi María Teresa
Published: February 2021

Los mamíferos fósiles de la Provincia de Santa Fé (Argentina) son escasamente conocidos. En este trabajo, se describen los restos mejor conservados de équidos (Mammalia, Perissodactyla) encontrados en los niveles pleistocenos aflorantes a lo largo del Río Paraná, cerca de la ciudad de San Lorenzo. El estudio comparativo con otros caballos provenientes de distintas localidades de América del Sur, en su mayoría argentinas y brasileñas, permite identificarlos como Equus (Amerhippus) neogeus e Hippidion principale. La sección estratigráfica analizada no cuenta con dataciones radiométricas o estudios paleomagnéticos que permitan calibrar con cierta precisión la edad de los depósitos portadores de équidos. En consecuencia, en base a correlaciones estratigráficas, los restos hallados estarían situados en un lapso que se extiende desde 128 ka (inicio del Pleistoceno Superior, estadio isotópico 5e) como edad máxima hasta momentos anteriores al comienzo del estadio isotópico 2e (28 ka).
A Lower Devonian (Emsian) species of the genus Bactrocrinites (crinoidea): Bactrocrinites robustus n. sp. (Cantabrian Mountains, NW Spain)
Authors: Pidal Raimundo
Published: February 2021

The only previous reference to Spanish bactrocrinitids (Crinoids) is found in Breimer (1962), who reports a specimen catalogued as TB73 on show at the museum of the Instituto Geológico y Minero de España (IGME) in Madrid. This specimen was found in the locality of Colle, León (Cantabrian Mountains) in rocks of the La Vid Group (Emsian). It was classified as Bactrocrinites sp., and was considered to be related to B. fusiformis (Roemer, 1844) and to B. muelleri (Jaeckel, 1895). New and exhaustive search in the locality of Colle have led to the discovery of two new specimens of the genus whose characteristics allow a new species to be defined: B. robustus n. sp., with a much more robust calyx than the other known species of the genus.
Paleobiogeografía y paleogeografía del Maastrichtiense Marino de la Patagonia, Tierra del Fuego y la plataforma continental Argentina, según sus foraminíferos bentónicos
Authors: Náñez Carolina , Malumián Norberto
Published: February 2021

La primera transgresión atlántica reconocida en la Patagonia es de edad Maastrichtiense, y superó en extensión a las posteriores transgresiones cenozoicas. La Patagonia extraandina y la extensa Plataforma Continental Argentina adyacente dieron lugar a un mar somero, con ambientes muy marginales ampliamente distribuidos y reflejados en sus asociaciones de foraminíferos de muy baja diversidad y de gran significado paleobiogeográfico. A partir de estas asociaciones, se han confeccionado dos mapas: el de la distribución de las sedimentitas marinas maastrichtienses, y el paleogeográfico correspondiente. El mar permaneció hasta el Daniense, sin que se compruebe una comunicación mediante un brazo marino intracontinental con la costa peruana y/o el Caribe. En la cuenca Austral se reconocen tres asociaciones de foraminíferos de ambientes extremos: foraminíferos aglutinados cosmopolitas; una segunda asociación de foraminíferos aglutinados de muy baja diversidad de ambientes marginales de plataforma estable; y una tercera, dominada por foraminíferos calcáreos de plataforma. En contraste, las asociaciones de la cuenca del Golfo de San Jorge, y en especial de la cuenca Neuquina-Colorado costa adentro, contienen conspicuos géneros y especies endémicos, a los que aquí se agregan: Tehuelchella caminosi n. gen. n. sp., Rosalina patagonica n. sp. y Protelphidium primitivum n. sp. Incluyendo los nuevos taxones propuestos, en el Maastrichtiense de la Patagonia septentrional se han reconocido en total 95 especies (85 de calcáreos y 10 de aglutinados), de las cuales aproximadamente 15 % son aparentemente endémicas del Hemisferio Sur, y el 10% endémicas de la región.
Taxonomic study of scallops (Pectinidae: mollusca, bivalvia) from Pliocene deposits (Almería, SE Spain)
Authors: Jiménez Antonio P , Aguirre Julio , Rivas Pascual
Published: February 2021

A taxonomic study has been carried out on scallops (family Pectinidae: Mollusca, Bivalvia) occurring in the lower-earliest middle Pliocene deposits of the Campo de Dalías, Almería-Níjar Basin, and Carboneras Basin (province of Almería, SE Spain). The recently proposed suprageneric phylogenetic classification scheme for the family (Waller, 2006a) has been followed. Twenty two species in twelve genera (Aequipecten, Amusium, Chlamys, Flabellipecten, Flexopecten, Gigantopecten, Hinnites, Korobkovia, Manupecten, Palliolum, Pecten, and Pseudamussium) and three subfamilies (Chalmydinae, Palliolinae, and Pectininae) have been identified. This number of species is higher than previously reported for the same area. Additionally, the phylogenetic classification followed in this paper modifies the species attributions formerly used.
