Mapping Potential Habitat and Range-Wide Surveying for the Texas Kangaroo Rat
Authors: Ott Silas L. , Veech Joseph A. , Simpson Thomas R. , Castro-Arellano Ivan , Evans Jonah
Published: July 2019

The Texas kangaroo rat Dipodomys elator is considered a species of conservation concern by state and federal agencies. There have been a limited number of sightings in only seven counties in northern Texas during the past 30 y. The apparent decline of the species has been attributed to habitat loss due to increasing conversion of natural areas into cropland. The magnitude and exact cause of the decline are difficult to determine because of insufficient data on the distribution of the species and its habitat within its relatively small geographic range. Habitat studies have focused on the microhabitat of burrows rather than a coarser-scale identification of habitat and its distribution within the species' historic range. Multiple species of Dipodomys have demonstrated strong associations with certain soil and land-cover types. Therefore our goal was to develop a range-wide map of potential habitat on the basis of the association of D. elator with specific soil and land-cover types. We used the map to guide roadside surveys and also updated the map with information on D. elator distribution obtained during the surveys. Over the course of two summers (2016 and 2017) we documented D. elator at 138 separate point locations in five counties. A geographic information system-based analysis of soil and land-cover data revealed that the species is associated with clay-loam and loam soils and mixed-grass/shortgrass prairie. We also found an unexpected association with cropland, although we do not know the exact extent to which D. elator actually uses cropland. The surveys provide an updated assessment of the species distribution and the maps of potential habitat indicate areas where the species may still exist.
La valeur théologique de l’assistance sociale dans les Églises d’étrangers d’Europe occidentale
Authors: Becker Judith
Published: July 2019

L’article étudie la signification théologique de la diaconie et de la fonction de diacre dans l’ecclésiologie réformée dans les Églises européennes occidentales. Il se concentre sur Jean Calvin et Martin Bucer, les Églises étrangères françaises et néerlandaises de Londres et sur les Églises de Valérand Poullain à Glastonbury et à Francfort. Quelle différence éventuelle y a-t-il entre la diaconie et l’office de diacre ? Quels devoirs les diacres avaient-ils et quels droits ont-été les leurs ? Quelle était la réalité de la diaconie et de l’office de diacre inclus dans l’ecclésiologie ?La réponse n’est pas uniforme à ces questions parce qu’il n’y avait pas de tradition homogène réformée. Martin Bucer et les Églises étrangères de Londres accordèrent beaucoup plus de l’importance à la diaconie que Jean Calvin et, après lui, Valérand Poullain. Ils soulignèrent tous l’importance de diacres et de la diaconie, mais l’ancrage dans leur ecclésiologie et les ordonnances ecclésiastiques diffère, d’une intégration plus implicite chez Jean Calvin, à la fondation dans la définition de l’Église comme communion dans laquelle les membres de l’Église se soutiennent mutuellement dans l’ecclésiologie d’a Lasco, et à l’argumentation de Martin Bucer qui unit la vie corporelle et spirituelle.
Visiter les malades : une œuvre de charité en version réformée, selon le pasteur Charles Drelincourt (1595-1669)
Authors: Carbonnier-Burkard Marianne
Published: July 2019

Œuvre de miséricorde traditionnelle, la visite des malades a été changée par la Réformation du XVIe siècle, en s’émancipant de l’« art de mourir » médiéval et du système des bonnes œuvres. Elle est devenue une pratique de consolation fraternelle et pastorale. C’est cette pratique qui est mise en scène dans les Visites charitables du pasteur Charles Drelincourt, au milieu du XVIIe siècle. La comparaison avec la visite des malades dans un manuel jésuite analogue, fait apparaître les spécificités confessionnelles, en particulier la désacralisation et la décléricalisation de la visite réformée des malades.
Les « bonnes œuvres » dans la prédication réformée française (1630-1680)
Authors: Daireaux Luc
Published: July 2019

Le propos revient d’abord sur le thème des « œuvres » tel qu’il est présenté et commenté par les prédicateurs réformés français du deuxième tiers du XVIIe siècle. Conformément au message calvinien mais en y apportant une coloration propre au Grand Siècle, les pasteurs tiennent un discours paradoxal, insistant sur la justification par la foi seule tout en exhortant aux « bonnes œuvres ». La deuxième partie de l’article considère les années 1660-1684, celles de la « réduction » du protestantisme en France. Le thème des « bonnes œuvres » prend alors une tonalité particulière. Dans une France réformée étranglée, les « ministres de la Religion prétendue réformée », bien conscients des « malheurs » et autres « afflictions » qui touchent le « petit troupeau », défendent la pratique de la charité et de la repentance, seul moyen d’apaiser la colère divine. Les souffrances constituent une école de la « persévérance », vertu devenue commune après la révocation de l’édit de Nantes et le départ de la plupart des pasteurs pour les pays du Refuge.
Les œuvres dans la Manne mystique de Claude Brousson : une sémiotique de l’engagement réformé sous la Révocation
Authors: Bernat Chrystel
Published: July 2019

Explorant le thème des œuvres dans l’édifice littéraire de Claude Brousson, cette enquête se présente comme une approche de la définition peu ou prou équivoque que le prédicateur leur attribue dans le contexte de la crise révocatoire. En s’enquérant de la sémiotique, qui a trait au signe et au sens, l’examen vise à déchiffrer l’interprétation que Brousson a des œuvres, et tend à analyser leur articulation à son herméneutique combative. Quelles valeurs le prédicateur du Désert leur confère-t-il ? Quels usages et fonctions leur prête-t-il dans les modalités de défense de la religion réformée ? Examinant les formules hétérodoxes que lui arrache l’impératif de redressement de sa communauté, le propos vise à cerner leur place de choix dans son programme de résistance spirituelle et les effets de la politique oppressive sur sa compréhension et sa valorisation militante des œuvres.
« La foi sans les œuvres est morte » : les protestants de Loudun et la pratique de la charité (1589-1685)
Authors: Bezzina Edwin
Published: July 2019

L’article examine la charité dans la communauté réformée de Loudun entre 1589 et 1685, en s’appuyant sur le registre du consistoire de Loudun et sur des testaments protestants et catholiques.Ces documents mettent en lumière quelques différences entre le corps consistorial et les testateurs protestants à l’égard de leurs idées concernant la charité. D’une part, les testateurs ont du faire face à des impératifs plus temporels et la charité n’a pas seulement servi comme moyen d’aider l’Église ou les pauvres de leur communauté. D’un autre côté, le consistoire et les testateurs, tous ensemble, hésitaient à appliquer la bienfaisance aux catholiques ou aux institutions charitables catholiques de la ville. La charité portait une signification pour l’âme du fidèle réformé avant la mort; elle était aussi un devoir qui correspondait aux commandements bibliques ainsi qu’une nécessité spirituelle.Ainsi est d’abord présenté le contexte très particulier de la communauté réformée de Loudun pendant cette période, et ensuite quelques textes bibliques pertinents. Ensuite l’accent est mis sur la charité dans le corps consistorial, les mobiles et la confessionalisation de la charité, et les legs testamentaires.
Le « comité » et l’assistance aux pauvres à La Rochelle au XVIIIe siècle (1775-1792)
Authors: Poton Didier
Published: July 2019

Entre 1755 et 1761, les protestants de La Rochelle se dotent d’un règlement ecclésiastique qui confie le gouvernement de l’Église à un « comité ». Le dépouillement des sept petits cahiers où sont transcrites les notes prises par les secrétaires successifs de cette institution permet d’appréhender son action. Un comptage des affaires débattues aboutit à conclure que l’assistance aux pauvres domine avant l’encadrement ecclésiastique. Dans un contexte où la pratique cultuelle se déroule au sein de trente-huit « sociétés », fruit d’un compromis entre les élites réformées et les représentants de la monarchie pendant la guerre de Sept Ans, il semble bien que l’assistance s’impose comme un élément d’unité et de dynamisme d’une communauté qui fonde le seul hôpital protestant du royaume dans cette période et dont une bonne part du fonctionnement repose sur le travail de diaconesses, épouses ou veuves de grands négociants. L’exemple rochelais permet de mettre en évidence le processus qui voit émerger la pratique de la philanthropie portée par des élites, ici de confession réformée, qui défendent de plus en plus ouvertement une politique de sécularisation de l’assistance aux pauvres.
Various Applications of Multifunctional Thin Films with Specific Properties Deposited by the ALD Method
Authors: Boryło Paulina , Szindler Marek , Lukaszkowicz Krzysztof
Published: July 2019

This paper presents application examples of atomic layer deposition method (ALD) adopted for production of multifunctional thin films for various usage such as passive, antireflection and transparent conductive films. First part of this paper introduces the mechanism of ALD process, in the rest of it, aluminum oxide (as passive and antireflection) and zinc oxide (as antireflection and transparent conductive) ALD thin films are presented. In the literature one can find reports on the use of the Al2O3 layer as passivating and ZnO layers as a transparent conductive oxide in diodes, polymeric and dye sensitized solar cells. In this article, the ALD layers were tested for their use in silicon solar cells, using their good electrical and optical properties. For examination of prepared thin films characteristics, following research methods were used: scanning electron microscope, atomic force microscope, X-ray diffractometer, ellipsometer, UV/VIS spectrometer and resistance measurements. By depositing a layer thickness of about 80 nm, the short-circuit current on the surface of the solar cell was increased three times while reducing the reflection of light. In turn, by changing the deposition temperature of the ZnO thin film, you can control its electrical properties while maintaining high transparency. The obtained results showed that the ALD method provide the ability to produce a high quality multifunctional thin films with the required properties.
Kikuchi-Fujimoto disease with multiple extra-nodal features - A clinical mimic
Authors: Mansoor C.A. , Shemin Z.
Published: July 2019

Extranodal involvement in Kikuchi’s disease is uncommon. A 31-year-old previously healthy Indian woman was admitted with high grade fever, multiple joint pain and skin rash for 3 weeks. She had negative anti-nuclear antibodies and had features of Kikuchi’s disease on lymph node biopsy. She also had multiple extranodal manifestations including erythematous maculopapular rash, symmetric polyarthritis and hepatosplenomegaly. Kikuchi’s disease with extranodal involvement can clinically mimic diseases like hematological malignancies, connective tissue disorders and certain infections. A lymph node biopsy plays a crucial role in making an accurate diagnosis by excluding other diseases. A discussion on the importance of differentiating Kikuchi’s disease from systemic lupus erythematosus is included.

Role of interventional radiology in the diagnosis and management of congenital extrahepatic portosystemic shunts: Two case reports
Authors: Mathai Sheetal V , Kondray Victor , Salloum Elias , Kukreja Kamlesh , Tavri Sidhartha
Published: July 2019

Congenital extrahepatic portosystemic shunt (CEPS) is a rare splanchnic venous malformation, wherein the portal venous outflow drains into the systemic venous circulation via a pathologic shunt. CEPS exhibits heterogeneous clinical behavior and angiography is the gold standard for evaluation of the portomesenteric communication to systemic vasculature. The potential severity of complications necessitates shunt closure. Here, we present two cases of CEPS. The first patient presented with an asymptomatic hyperammonemia and was found to have a Type 1 CEPS with absence of intrahepatic portal system. The second patient was asymptomatic and was incidentally found to have a Type 2 CEPS on imaging with normal intrahepatic portal system. Both patients were successfully treated with endovascular occlusion of the CEPS.
Review of Cases of Angiostrongyliasis in Hawaii, 2007–2017
Authors: Johnston David I. , Dixon Marlena C. , Elm Joe L. , Calimlim Precilia S. , Sciulli Rebecca H. , Park Sarah Y.
Published: July 2019

Angiostrongyliasis, caused by the Angiostrongylus cantonensis roundworm, became reportable in the state of Hawaii in 2007. We confirmed 82 reported cases between 2007 and 2017. There was a median of seven cases per year, and the majority (57%) of cases occurred between January and April. Most (83%) cases were found on the island of Hawaii, with geographic information system (GIS) analysis identifying hot spots on the east side of the island. However, cases were identified on the other major islands as well, suggesting the risk of exposure is present statewide. Comparisons of cases from 2007 to 2017 with cases from previous assessments found no statistical differences in cerebrospinal fluid results, peripheral blood results, or ages of cases. However, differences in geographic distribution of the cases were statistically significant. Improved testing and increasing awareness of the disease have contributed to our efforts to better understand the general risk factors and modes of transmission present in Hawaii and also helped improve our prevention efforts, although we still do not fully understand the specific causes of cases being concentrated in certain parts of the state over others. Continued outreach efforts, including public forums and publication of preliminary clinical guidelines, aim to inform and improve our public health response and efforts to prevent angiostrongyliasis.
Study of Serum Superoxide Dismutase and Malondialdehyde Levels during Normal Pregnancy
Authors: Kaur Manjeet , Bassi Roopam , Mehta Kiran , Kaur Deepinder
Published: July 2019

Introduction

Pregnancy is accompanied by a high-energy demand of all body functions and an increased oxygen requirement, which can give rise to increased levels of oxidative stress.

Aims and objectives

The present study was done to assess the levels of oxidative stress in healthy pregnant females by estimating serum superoxide dismutase (SOD) and malondialdehyde (MDA) levels and comparing these with nonpregnant females.

Materials and methods

The study was conducted on 88 female subjects in the age group of 20 to 40 years, who were placed in two groups. Group I consisted of 50 healthy nonpregnant females. Group II consisted of healthy pregnant females further subdivided into three subgroups: Group IIa (1st trimester) n = 38, group IIb (2nd trimester) n = 32, and group IIc (3rd trimester) n = 30. The same subjects were followed up till the 3rd trimester. There was a drop in the number of subjects from 38 to 32 in the 2nd trimester and from 32 to 30 in the 3rd trimester due to noncompliance and development of complications of pregnancy. The subjects were assessed for hemoglobin (Hb), MDA, a marker for lipid peroxidation, and SOD, an antioxidant enzyme along with certain physiological parameters like height, weight, body mass index, and blood pressure in the three trimesters.

Results

The levels of SOD and MDA were significantly raised with the progression of pregnancy. There was a fall in Hb levels in the 3rd trimester. But no significant correlation could be drawn between the measured parameters in all the trimesters.

Conclusion

Pregnancy is definitely associated with oxidative stress to the body. Both peroxidation and antioxidation reactions are enhanced during pregnancy. With these findings, we therefore conclude that antioxidant supplements should be prescribed in early pregnancy to prevent the overwhelming of oxidative stress in pregnant females.

Occipitalization of Atlas: A Case Report with its Ontogenic Basis and Review of Literature
Authors: Piplani Sanjay , Kullar JS
Published: July 2019

Introduction

Anatomy of the cervical vertebrae allows free flexion, extension, and rotation, which take place almost entirely in the first two cervical vertebrae. Variation in the articulation of upper cervical spine-like congenital fusion of the atlas to the base of the occiput, i.e., occipitalization of the atlas, is one of the common skeletal abnormalities. Such variations will produce irregular motion and at times a definite instability of the joint involved.

Conclusion

Considering the nature and functional importance of the joints in relation to these bones, the resulting disability is one of the rare occurrences and deserves special attention. Such patients exhibit neurological signs and symptoms usually no sooner than the second decade. Thus, anatomy, variations, and anomalies of the craniocervical junction are of high clinical importance to many specialties like anatomists, neurosurgeons, radiologists, and manipulative therapists, as they markedly influence mobility and stability of the cervical region.

Appendicular Mucocele—A Diagnostic Dilemma: Managed Laparoscopically
Authors: Gurpreet Bhangu , Kamal Sachdeva
Published: July 2019

Appendicular mucocele is obstructive dilatation of the appendicular lumen by mucinous secretions. In most of the cases, it is caused by Mucinous cystadenoma and rarely by Mucinous cystadenocarcinoma. This rare disorder has a varied clinical presentation, with more than half of the patients being asymptomatic. We report the case of a 65-year-old man who presented with intermittent abdominal colicky pain and altered bowel habits. In spite of extensive preoperative investigations, no definitive diagnosis was made. On diagnostic laparoscopy it was found to be appendicular mucocele. We electively performed a laparoscopic appendectomy. As there is a risk of malignancy in the mucocele, we used an endobag to retrieve the specimen. Histological examination confirmed it as a Mucinous cystadenoma.

Students' Perceptions to Introduction of Problem-based Learning Modules in Anatomy
Authors: Sharma Punita , Sachdeva Kanika
Published: July 2019

Introduction

It is necessary for core knowledge of anatomy to be assimilated by all doctors in order to practice, but if it can improve their understanding of what they do and why they do it, this surely has to be of benefit for both the safety of the patient and satisfaction of the doctor as a professional. This intervention aimed to study whether problem-based learning (PBL) as an educational strategy can help in improving the quality of gross anatomy teaching and the attitude of students toward the learning method in India.

Materials and methods

The study sample included 100 students who were assigned to 10 groups (10 students in each group). Each PBL tutorial was conducted over three sessions. Pre- and post-tutorial tests were conducted. Data collection was done by a questionnaire survey to examine the students' learning attitudes and perceptions toward this platform as a possible learning tool. The obtained data were compared, and the main themes were determined.

Results

We found out the satisfaction of students with this learning method and the students' interest and ability for improvement after this teaching method. Also, the problems and obstacles the students faced in this learning mode were highlighted.

Conclusion

The study clearly pointed out that PBL benefits a lot of students in the study of gross anatomy despite the existing problems. In future, we should implement PBL combined with the characteristics of traditional anatomy teaching.

Health Manpower Planning
Authors: Chhina Rajoo S , Chhina Rajdeep S , Sidhu Ananat , Bansal Amit
Published: July 2019

Manpower is the most crucial resource toward delivery of health planning. Health manpower refers to people who are trained to promote health, to prevent and to cure diseases, and to rehabilitate the sick. The aim of manpower planning is to make available the right kind of personnel in the right number with appropriate skills at the right place at the right time doing the right job. Various types of health resources are doctors, nurses, pharmacists, lab technicians, radiographer health assistants, health workers, auxiliary nurse midwife (ANM), accredited social health activists (ASHAs), anganwadi workers, trained dais, and so on. Currently, developing countries including India lag behind suggested norms of required health manpower. Presently, India produces 30,000 doctors, 18,000 specialists, 30,000 Ayurveda, Yoga and naturopathy, Unani, Siddha, and Homeopathy (AYUSH) graduates, 54,000 nurses, 15,000 ANMs, and 36,000 pharmacists annually. This production is not equal across the states, leading to unequal distribution of doctors. Such a skewed distribution results in large gaps in demand and availability. Various reasons for this are skewed production of health manpower, uneven human resource deployment and distribution, disconnected education and training, lack of job satisfaction, professional isolation, and lack of rural experience. The 12th Plan should aim to expand facilities for medical, nursing, and paramedical education; create new skilled health worker categories; enable AYUSH graduates to provide essential health care by upgrading their skills in modern medicine through bridge courses; establish a management system for human resource in health to actualize improved methods for recruitment, retention, and performance; put in place incentive-based structures; create career tracks for professional advancement based on competence; and, finally, build an independent and professional regulatory environment.

O circuito das drogas: mídia e arte na crítica contemporânea
Authors: Bragança Maurício De
Published: July 2019

A exposição Una linea de polvo, arte y drogas en América Latina fez dialogarem o campo das artes plásticas e visuais, e o fenômeno do narcotráfico. Segundo o curador Santiago Rueda, a ideia era entender “as dimensões de um problema global”, fazendo expandir a ideia de “narcotráfico” para uma compreensão maior da questão como um “problema narco”, marcado por uma forte presença da cultura midiática. As obras expostas implodiam as distâncias entre mídia e arte, gerando um deslocamento do lugar da crítica de arte tradicional ao ter que lidar com questões que englobam um campo irrestrito de proposições que passam pela economia, medicina, direito e política internacional no âmbito da estética, ética e cultura. Dessa forma, a crítica de arte se constrói na interface com outros domínios para dar conta desse tipo de produção contemporânea, privilegiando o campo midiático.
A mídia manipula quem tem cabeça fechada: adolescentes periféricos e a crítica ao jornalismo
Authors: Doretto Juliana
Published: July 2019

Em pesquisa-ação com jovens do ensino médio, moradores de bairros periféricos e/ou de baixa renda, investigamos como eles criticam o jornalismo brasileiro e de que forma se mantêm informados. O estudo revela distanciamento e desconfiança desse jovem em relação a fontes jornalísticas tradicionais — ainda que reconheçam a sua importância —, mas também a emergência de novas rotinas noticiosas, influenciadas por plataformas digitais. Segundo os grupos focais realizados, o consumo do jornalismo profissional ocorre sobretudo pela TV, por influência de hábitos familiares, e por alguns sites noticiosos. Por iniciativa própria, os jovens recorrem a posts em redes sociais, vídeos no YouTube e consultas a agregadores, para acessar o que eles identificam como “notícias” importantes para o dia a dia, ainda que essas informações nem sempre venham da mídia jornalística tradicional.
Polyphyly and homoplasic structures in rhizosolenioid diatom genera: a review
Authors: Jordan Richard W. , Ashworth Matt P. , Uezato Yuki , Manning Schonna R.
Published: July 2019

Background and aims – Traditionally, extant rhizosolenioid diatom genera have been placed in a single family, the Rhizosoleniaceae. However, preliminary molecular data suggested that the family might be polyphyletic. Therefore, a literature review of the morphological, ultrastructural and molecular data of the rhizosolenioid genera was undertaken.

Methods – In addition to the literature survey, the location of the rimoportula in a number of rhizosolenioid genera was investigated by breaking the valves and observing the fragments in the scanning electron microscope.

Key results – The data provides strong support for the previous separation of Proboscia and Rhizosolenia at the family level (Probosciaceae vs. Rhizosoleniaceae), with the rimoportula being located at the tip of the proboscis in Proboscia, or with an internal labia at the base of the hollow tubular rimoportula (= spine or process) in Rhizosolenia and Pseudosolenia.

Conclusions – The data suggests that a number of rhizosolenioid genera should be transferred to other families, and that gene sequences of two genera (Dactyliosolen and Neocalyptrella) are needed as their morphological features differ markedly from those of the Rhizosoleniceae s. str. (Rhizosolenia, Guinardia, Pseudosolenia).
Gomphonella olivacea (Bacillariophyceae) – a new phylogenetic position for a well-known taxon, its typification, new species and combinations
Authors: Jahn Regine , Kusber Wolf-Henning , Skibbe Oliver , Zimmermann Jonas , Van Anh Tu , Buczkó Krisztina , Abarca Nélida
Published: July 2019

Background and aims – Within the project “German Barcode of Life – Diatoms” common diatoms of German waters were routinely isolated and cultivated. In order to understand the taxonomy and phylogeny of the genus Gomphonema, one of the most common taxa of Central Europe, known currently either under the name Gomphonema olivaceum in Europe or Gomphoneis olivacea in America, was studied.

Methods – Twenty unialgal strains were established from five different water bodies in Germany and one from Lake Balaton, Hungary, which supplied molecular data (18S V4 and rbcL) besides morphometric and ultrastructural data. In addition, on eight populations from different water bodies including the type from Denmark, morphometric and micromorphological studies by light and scanning electron microscopy were performed.

Key results – Molecular and micromorphological data show that the target taxon neither belongs to Gomphonema Ehrenb. nor to Gomphoneis Cleve. By reinstating the genus name Gomphonella Rabenh., the nomenclatural and taxonomic enigma of this taxon is solved, and with the presentation of the type by Hornemann the authorship of the epithet is clarified. Molecular data for the unialgal strains and several environmental clones show that there is more diversity in the Gomphonella olivacea clade than can be identified morphologically. In addition, the establishment of the new species Gomphonella coxiae and Gomphonella acsiae is supported. The molecular data classified Gomphonella species as belonging to the Cymbellales but not to the Gomphonemataceae. In addition, molecular data put Gomphoneis tegelensis R.Jahn & N.Abarca also into Gomphonella. In order to make the genera Gomphoneis and Gomphonema monophyletic, their astigmate members are transferred to Gomphonella.

Conclusions – The results clarify that the gomphonemoid outline is not restricted to the family Gomphonemataceae but seem to be distributed across the entire order Cymbellales. This is shown in this paper for the revived genus Gomphonella, which contains the astigmate group of Gomphoneis and Gomphonema besides the longly disputed G. olivacea. Only a polyphasic approach, combining molecular and micromorphological data for taxonomy, nomenclatural evaluation, and observations from clonal cultures can reveal the full intricacies of evolutionary relations.
Morphological reconsideration of the araphid genus Pseudostaurosira (Bacillariophyceae), a revision of Gedaniella, Popovskayella and Serratifera, and a description of a new Nanofrustulum species
Authors: Morales Eduardo A. , Wetzel Carlos E. , Novais Maria Helena , Buczkó Krisztina , Morais M. Manuela , Ector Luc
Published: July 2019

Background and aims – As a result of the description of many new species, reanalyses of type material, and information becoming available on valve morphogenesis in small araphid diatoms lacking a rimoportulae, the existing classification scheme at the genus level needs revision. Because morphological information has increased manyfold since the system provided by Williams & Round (1987), it may now be possible to find distinguishing characters in order to produce a more stable and useful framework, encompassing a morphogenetic perspective, which could then guide the placement of newly discovered taxa. This new framework could also be used to help assess the molecular information generated for the group, based on which many new genera are being erected, but perhaps without proper pondering of morphological data.

Methods – A thorough review was made of available published information on the ultrastructure of small-celled araphid diatoms lacking rimoportulae. In addition, image databases were searched, and new light and scanning electron microscopical observations made of some hitherto undescribed species.

Key results and conclusions – We provide a table of putative distinguishing features for nine genera (Nanofrustulum, Opephora, Pseudostaurosira, Pseudostaurosiropsis, Punctastriata, Sarcophagodes, Stauroforma, Staurosira and Staurosirella), together with a discussion on their value for discriminating these small diatoms using a morphogenetic perspective. Based on our findings, we amend the genus Pseudostaurosira, establishing wide and short vimines as its most characteristic feature. We use our system in describing a new species from Bolivia, which we place in Nanofrustulum based on its quasifract copulae, the distinguishing trait of the genus. The new species is distinguished from its congeners by its heteropolar valves, apical pore field features, and the multiseriate areolae. We also examine the three genera Popovskayella, Gedaniella, and Serratifera, the latter two recently erected based on molecular information. Since none of these latter genera pass the morphogenetic evaluation we think is essential, we place them in synonymy with other genera and provide the consequent nomenclatural changes. Finally, we make several new combinations in Nanofrustulum, Pseudostaurosira, Sarcophagodes and Staurosirella.
Novel marine diatom ssRNA virus NitRevRNAV infecting Nitzschia reversa
Authors: Toyoda Kensuke , Kimura Kei , Osada Keigo , Williams David M. , Adachi Tomoko , Yamada Katsumasa , Tomaru Yuji
Published: July 2019

Background and aims – Diatoms are one of the most species rich groups of organisms on Earth. They are fundamental in supporting the biomass of the natural environment. The presence of marine viruses can greatly influence diatom diversity in their natural environment and has attracted interest from multi-disciplinary research teams after a diatom infected virus was reported for the first time in the 21st century. As initial research in this field demonstrated, for the acquisition of a new virus it is important to learn about their infect hosts. Therefore, we have been searching for new viruses that infect diatoms.

Methods – A clonal host species Nitzschia reversa was isolated from natural sea water. Aliquots of the filtrates obtained from this sea water were inoculated to yield the exponentially-growing isolated host species. The resultant lysate was used as a clonal lysate and treated as a clonal virus suspension. The suspension was then used for further analysis of various biochemical studies.

Key results – We discovered and isolated a new virus that infected the pennate diatom Nitzschia reversa. Since this newly discovered virus was a single strand RNA virus, it has capsid proteins with 30 nm size icosahedron without an envelope. The species epithet is NitRevRNAV.

Conclusions – In this study, we described the morphology, genome type and partial sequences, as well as lytic activities, of the new species NitRevRNAV. Of note, the virus harbours a positive-sense single-stranded RNA genome. These features were highly similar to those of previously known diatom RNA viruses therefore NitRevRNAV is a new member of the genus Bacillarnavirus in the Order Picornavirales.
Adlafia neoniana (Naviculaceae), a new diatom species from forest streams in Puerto Rico
Authors: Ciugulea Ionel , Burroughs Summyr , Defrancesco Chiara , Spitale Daniel , Charles Donald F. , Lange-Bertalot Horst , Cantonati Marco
Published: July 2019

Background and aims – The samples on which this study is based were collected in two streams in Puerto Rico as part of a long-term monitoring program conducted by the National Ecological Observatory Network (NEON). Detailed study of the diatom assemblages revealed the occurrence of a new diatom species belonging to the genus Adlafia.

Methods – The study considered 82 samples of epilithic diatoms from two streams in Puerto Rico (Rio Cupeyes and Rio Guilarte) subjected to different degrees of anthropogenic impacts. The new species description is based on high-quality Nomarski (DIC) LM micrographs which document the full spectrum of shape variability along the size diminution series (including girdle views), and SEM images documenting valve ultrastructure (including detailed internal views). In addition we provide information about ecological preferences with respect to trophic state / nutrients, habitat within the stream channel / microhabitat (riffle, run, pool), and season of maximum occurrence.

Key results – The new species is described as Adlafia neoniana Cantonati sp. nov. It resembles A. drouetiana but has lanceolate (instead of triundulate) outline, slightly-subcapitate to subrostrate ends (instead of subcapitate to capitate), and higher stria density. It is also similar to A. muscora but differs by elliptic-lanceolate (instead of linear-lanceolate) outline, broader valves, and higher stria density. Moreover, the new species was most abundant in an undisturbed, oligotrophic, shaded forest stream whilst A. drouetiana is known from Brazil to be tolerant to organic pollution and eutrophication.

Conclusions – Adlafia neoniana can be differentiated from other similar species in the light microscope by recognizable characters or character combinations. Its discovery and characterization is a contribution to the knowledge of the still understudied biodiversity of microorganisms in tropical streams.
On the identity of the rare Fragilaria subconstricta (Fragilariaceae), with Fragilaria species forming ribbon-like colonies shortly reconsidered

Published: July 2019

Background and aims – During phytoplankton surveys of a freshwater pond in Northeastern France, Fragilaria subconstricta (Bacillariophyceae) was observed. This rare diatom was present in large numbers in several plankton samples from Lachaussée Pond in the French Grand Est region.

Methods – The morphology of Fragilaria subconstricta was examined in detail using light and scanning electron microscopy. Its identity is discussed and it is compared to the morphologically most similar species, especially Fragilaria capucina, F. mesolepta Rabenhorst, F. neointermedia and F. tenuistriata.

Key results – Fragilaria subconstricta produces ribbon-like colonies and has narrow linear-lanceolate valves with slightly rostrate ends. The central area is rectangular, usually small or even absent. Spatulate linking spines are present all along the valve margins and a single rimoportula is located near one apex at the valve face-mantle junction. An amended diagnosis and new synonyms are proposed for this species. Additionally, the type material of Fragilaria mesolepta and a population of the very rare species Fragilaria capucina have been investigated and illustrated.

Conclusions – Fragilaria subconstricta and F. tenuistriata are synonyms. Fragilaria capucina s. str. is a rare species in Europe, and the majority of records for this species should be considered part of the Fragilaria capucina “Sippenkomplex” sensu Krammer & Lange-Bertalot (1991).

Abstract. We explore the impacts of short-term emission controls on haze events in Beijing in October–November 2014 using high-resolution Weather Research and Forecasting model with Chemistry (WRF-Chem) simulations. The model reproduces surface temperature and relative humidity profiles over the period well and captures the observed variations in key atmospheric pollutants. We highlight the sensitivity of simulated pollutant levels to meteorological variables and model resolution and in particular to treatment of turbulent mixing in the planetary boundary layer. We note that simulating particle composition in the region remains a challenge, and we overpredict NH4 and NO3 at the expense of SO4. We find that the emission controls implemented for the Asia-Pacific Economic Cooperation (APEC) summit period made a relatively small contribution to improved air quality (20 %–26 %), highlighting the important role played by favourable meteorological conditions over this period. We demonstrate that the same controls applied under less favourable meteorological conditions would have been insufficient in reducing pollutant levels to meet the required standards. Continued application of these controls over the 6-week period considered would only have reduced the number of haze days when daily mean fine particulate matter exceeds 75 µg m−3 from 15 to 13 d (days). Our study highlights the limitations of current emission controls and the need for more stringent measures over a wider region during meteorologically stagnant weather.
The probabilistic hydrological MARCSHYDRO (the MARkov Chain System) model: its structure and core version 0.2
Authors: Shevnina Elena , Silaev Andrey
Published: July 2019

Abstract. The question of the environmental risks of social and
economic infrastructure has recently become apparent due to an increase in
the number of extreme weather events. Extreme runoff events include floods
and droughts. In water engineering, extreme runoff is described in terms of
probability and uses methods of frequency analysis to evaluate an exceedance
probability curve (EPC) for runoff. It is assumed that historical
observations of runoff are representative of the future; however, trends in
the observed time series show doubt in this assumption. The paper describes a
probabilistic hydrological MARCSHYDRO (the MARkov Chain System) model that can be applied to
predict future runoff extremes. The MARCSHYDRO model simulates
statistical estimators of multi-year runoff in order to perform future
projections in a probabilistic form. Projected statistics of the
meteorological variables available in climate scenarios force the model.
This study introduces the new model's core version and provides a user guide
together with an example of the model set-up in a single case study. In this
case study, the model simulates the projected EPCs of annual runoff under
three climate scenarios. The scope of applicability and limitations of the
model's core version 0.2 are discussed.
A Python-enhanced urban land surface model SuPy (SUEWS in Python, v2019.2): development, deployment and demonstration
Authors: Sun Ting , Grimmond Sue
Published: July 2019

Abstract. Accurate and agile modelling of cities weather, climate,
hydrology and air quality is essential for integrated urban services. The
Surface Urban Energy and Water balance Scheme (SUEWS) is a state-of-the-art
widely used urban land surface model (ULSM) which simulates
urban–atmospheric interactions by quantifying the energy, water and mass
fluxes. Using SUEWS as the computation kernel, SuPy (SUEWS in Python) uses
a Python-based data stack to streamline the pre-processing, computation and
post-processing that are involved in the common modelling-centred urban
climate studies. This paper documents the development of SuPy, including
the SUEWS interface modification, F2PY (Fortran to Python) configuration and
Python front-end implementation. In addition, the deployment of SuPy via PyPI
(Python Package Index) is introduced along with the automated workflow for
cross-platform compilation. This makes SuPy available for all mainstream
operating systems (Windows, Linux and macOS). Three online tutorials in
Jupyter Notebook are provided to users of different levels to become
familiar with SuPy urban climate modelling. The SuPy package represents a
significant enhancement that supports existing and new model applications,
reproducibility and enhanced functionality.
Case Study: Risk Analysis by Overtopping During an Upstream Landslide in Peñitas Dam, Mexico
Authors: Marengo Humberto J. F. , Aldama Alvaro A.
Published: July 2019

Abstract. Risk and uncertainty analysis by mathematical and statistical methods is often used to assess systematic risks and uncertainties. This research presents the procedure and application of risk and reliability analysis to dam overtopping (Peñitas) located downstream of a natural dam that could have failed. For the analysis are used six statistical variables and their uncertainties, the peak flood of the upstream dam, are evaluated with empirical formulas. The highest water levels of the break dam event were computed using reservoir routing with an explicit equation developed by the authors. Afterward, the overtopping risk analysis of Peñitas Dam was assessed for different stages of excavation of the natural dam that were made during making a sensitivity analysis of duration of dam break event, and also is calculated the possible upper elevation of Peñitas dam, finding that is a recommended practice measurement in similar further cases. A methodology to do an orderly and consistently analysis of risk is proposed to solve similar situations.
