Having visits: Considerations on the researcher-as-host in participatory projects
Authors: Clausen Rosa Tolnov
Published: May 2020

The Weaving Kiosk project was a series of nine temporary weaving spaces that took place in Denmark, Sweden, Finland and Iceland throughout 2017 and 2018. Each Kiosk provided catalysts for conversations beyond preconceived ideas of what hand weaving in northern Europe means today. Using the two-year participatory Weaving Kiosk project as a case study, this article seeks to complement Donna Haraway’s concept of ‘visiting’ as a research inquiry method with the idea of ‘having visits’ as a method for approaching participation. The methods of visiting and having visits share their central ambition, but differ in their motion vectors and material densities. While visiting describes an outward discovery into unknown physical and intellectual territory, having visits resonates as an inward discovery into an authored material territory through dialogue with the visitor, space and host. This article considers how the dialogical research tools used in the Weaving Kiosk become testable through having visits.
Putting the ‘punk’ back into pop-punk: Analysing presentations of deviance in pop-punk music
Authors: Grebe Justus , Winkler Robert A.
Published: May 2020

Writing on pop-punk, the melodic branch of punk that rose to fame in the mid-to-late-1990s, usually centres on the pop aspect of the genre: its popularity, polished sound and commercialization. Defining punk as a culture of deviance, this article in contrast examines the punk aspect of pop-punk by analysing the ways deviance is presented in the music videos ‘All the Small Things’ by blink-182, ‘In Too Deep’ by Sum 41, and ‘Original Prankster’ by the Offspring, all released at the turn of the millennium. Understanding music videos as media advertising a song, an album and an artist and analysing the interplay of visuals, music and lyrics therein, we argue that blink-182 and Sum 41 present themselves as deviant by staging a notion of authenticity, ridiculing mainstream pop and appropriating the ‘prankster’ stereotype, while the Offspring take a more nuanced stance on the matter of pranking. Concluding, we attribute this difference to the generational gap between the bands and briefly identify the different waves of pop-punk.
Surveilling lesbians: The Birds, Hitchcock’s narrative cinema and the criminalization of sexuality
Authors: O’Donnell Brenden
Published: May 2020

This article analyses The Birds in order to distinguish a form of heteropatriarchy characterized by the development of surveillance practices. In the earlier films Vertigo and Rear Window, female characters were represented as intensely desirable, yet also disturbingly unattainable. This article is dissatisfied with the explanation that Hitchcock’s unattainable woman is an example of the 1960s developing lesbian subjectivity. Instead, I use The Birds to prove that Hitchcock’s representation of women has in mind the projects of arranging women for interrogation, eavesdropping on their conversations and intruding upon their intimate moments. Hitchcock’s voyeurism, construable as ambivalent in earlier films, manifests in The Birds as a surveillance practice that assumes access over the private lives of women: a heteropatriarchal strategy that keeps women’s bodies, if not accessible for men, punishable by them. By keeping tabs on the ways that women grow intimate with one another instead of with men, Hitchcock’s cinema moves from narrative to surveillance, blurring the distinction between cinematography and security footage.

VOTOS DISSONANTES: A DESARMONIA NAS DECISÕES COLEGIADAS DO SUPREMO TRIBUNAL FEDERAL
Authors: Romanelli Sandro Luís Tomás Ballande
Published: May 2020

Este artigo trata da deliberação no Supremo Tribunal Federal a partir da descrição de seu processo decisório. Procura-se demonstrar que o processo deliberativo do STF tem sido insuficiente para harmonizar os debates de seus 11 ministros, resultando num inevitável impasse. Inicialmente são detalhadas as regras institucionais que atribuem poderes ao relator (como o poder de agenda e de elaboração da ementa) e que organizam as sessões de julgamento e a formação do acórdão. Segue-se uma análise de seus efeitos, destacando as incongruências entre o que consta nos acórdãos e o que de fato restou documentado nas transcrições dos debates e votos individuais dos membros do Tribunal em dois processos relacionados, a ADPF 130 e a Reclamação 9.428/DF.

A vigilância de epizootias em primatas não humanos (PNH) é uma importante estratégia que visa, prioritariamente, a identificação precoce da circulação viral dos agentes da febre amarela e da raiva, na prevenção de riscos à saúde da coletividade. O presente artigo, de cunho descritivo, analítico e retrospectivo, utilizou dados da vigilância passiva de epizootias em PNH realizada pelo Centro de Controle de Zoonoses e Doenças de Transmissão Vetorial de Niterói, Rio de Janeiro, no período de 2017 a 2018. No período estudado as epizootias envolveram 203 PNH, da família Callitrichidae. Foram analisados laboratorialmente somente 81,8% (n=166) dos primatas recolhidos, em função do estado de conservação das carcaças. A região Oceânica de Niterói e o bairro Fonseca destacaram-se na quantidade de carcaças recolhidas, havendo concentração em áreas de média e alta densidades de urbanização do município. Houve predomínio do aparecimento de carcaças no período de janeiro a maio. Não foram encontrados PNH positivos para raiva e foi encontrada prevalência baixa de febre amarela nos animais analisados laboratorialmente (1,26% em 2017 e 0,6% no período), com identificação de um único caso, no período pré-sazonal.
Tipologias dos neologismos
Authors: Jesus Ana Maria Ribeiro de
Published: May 2020

Desde as primeiras investigações sobre o fenômeno da neologia, várias tipologias para a categorização das unidades lexicais neológicas vêm sendo propostas. O presente artigo busca apresentar uma breve descrição das tipologias mais presentes nos trabalhos da área. A maioria delas, principalmente aquelas adotadas pelos Observatórios de Neologia, são classificações baseadas em processos de formação lexical. Há grande diferença nas propostas de classificação, mas, de modo geral, é possível sintetizar os processos de formação em três tipos fundamentais: processos formais, semânticos e por empréstimo. Refletimos, igualmente, sobre a importância de se considerarem os fatores pragmático e discursivo como inerentes a qualquer unidade neológica e, consequentemente, a qualquer proposta de tipologização.
Neologismos por derivación en la traducción del portugués al español
Authors: Díaz Ferrero Ana María , Porlán Moreno Rafael
Published: May 2020

El proceso de formación de palabras en portugués y en español presenta falsas similitudes que obligan al traductor, particularmente cuando se trata de procesos con poco tiempo para la reflexión como es el caso de la traducción a vista (TAV), a prestar especial atención a la forma con el objeto de evitar errores. En este artículo presentamos una propuesta didáctica destinada a desarrollar la competencia léxica y adquirir habilidades de reformulación para evitar calcos que den lugar a neologismos innecesarios en el proceso de traducción. Se propone una actividad de TAV distribuida en cuatro fases: 1. traducción a vista sin preparación para tomar conciencia de los posibles errores; 2. activación léxica; 3. lectura y comprensión del texto original, y 4. reformulación. Esta propuesta didáctica pone de manifiesto que al traducir estos vocablos del portugués al español y viceversa hay que tener en cuenta factores como la tradición en el proceso de derivación de cada lengua y la frecuencia de uso de las palabras, así como las características de cada texto para emplear el término adecuado y ofrecer un texto meta que reproduzca el contenido semántico del original de la forma más natural e idiomática.

W artykule przedstawiam wyniki jakościowej i ilościowej analizy 555 pytań zawartych w scenariuszach lekcji języka polskiego, których autorami są studenci III roku filologii polskiej. Posiłkuję się przy tym klasyfikacją Elizabeth Perrott, która, uwzględniając „taksonomię celów edukacyjnych” Benjamina Blooma, zaproponowała podział pytań ze względu na typ procesu myślowego uruchomianego podczas odpowiedzi, wyróżniając pytania niższego rzędu (przypominanie, zrozumienie, zastosowanie) oraz pytania wyższego rzędu (analiza, synteza i ewaluacja). Tekst składa się z dwóch zasadniczych części. W pierwszej prezentuję kategorię pytania z perspektywy pragmatycznej, gramatycznej i dydaktycznej, w drugiej przedstawiam i komentuję wyniki analizy jakościowej i ilościowej pytań, która jednoznacznie wskazuje na nadużywanie przez studentów pytań niższego rzędu (ponad 75% w badanym materiale), służących jedynie egzekwowaniu wiedzy.
Między słowem a milczeniem: o przywracaniu sensu w dialogu z młodzieżą we współczesnej szkole
Authors: Błachowicz Elżbieta
Published: May 2020

Utożsamiana z przestrzenią autentycznego rozwoju i wychowania oraz rzetelnego, opartego na prawdzie kształcenia szkoła może znacząco przyczynić się do zmian w zakresie ładu moralnego i zwiększenia szans na zbudowanie wspólnoty dojrzałych obywateli, osób otwartych na dialog, a także doświadczenie inności i bogactwa drugiego człowieka. Wychowanie ludzi myślących, rozumiejących fundamentalne znaczenie etycznej komunikacji w relacjach międzyludzkich, jest najlepszym sposobem na modelowanie właściwych postaw młodego pokolenia. Niezbędnym impulsem do rozwoju, wysiłku świadomego kształtowania tożsamości mogą stać się lekcje języka polskiego jako czas ważnych spotkań w dialogu, inspirujących uczniów do pogłębiania w wolności prawdy o sobie i innych. W procesie budowania zintegrowanej osobowości potrzebne jest ukierunkowanie, odnalezienie unikatowego sensu życia, stanowiącego najsilniejszą motywację do działania. Edukacja polonistyczna, zakorzeniona aksjologicznie w tradycji judeochrześcijańskiej, powinna być zorientowana na wielowymiarowy charakter człowieka i twórcze podejście do osobowości.
Kali czy Nabu? Jaka literatura i jaki nauczyciel będą uczyć rozumienia drugiego człowieka?
Authors: Janus-Sitarz Anna
Published: May 2020

Współczesna literatura dla dzieci i młodzieży zdecydowanie wypełnia swoją humanistyczną misję uczenia szacunku wobec Innego i zrozumienia meandrów związanych z powszechną dziś migracją i dylematami wielokulturowości. Jednak w Podstawie programowej nie ma miejsca na tę literaturę, co więcej, umocniła się klasyka, wobec której wciąż trwają spory, czy nie utrwala groźnych stereotypów narodowych. Kluczowe pytanie dla polskich badaczy brzmi: czy prace Henryka Sienkiewicza powinny być nadal czytane w szkołach, zwłaszcza w okresie narastania retoryki nacjonalistycznej? Głównym wyzwaniem dla nauczycieli literatury jest: jak rozmawiać w klasie na temat arcydzieł niepoprawnych politycznie? Próbując odpowiedzieć na te pytania, przedstawiam efekty badań własnych, dotyczących wpływu wybranej lektury literatury dziecięcej na zmianę w podejściu studentów do klasyki literackiej. Różnice w scenariuszach z powieści Sienkiewicza, pisanych przez przyszłych nauczycieli przed lekturą opowieści Jarosława Mikołajewskiego o małym imigrancie oraz tworzonych po takiej lekturze, przynoszą pewne rozwiązania dydaktyczne.

Na cmentarzysku polonistycznych podręczników – kilka myśli
Authors: Uryga Zenon
Published: May 2020

Szkolne podręczniki literatury, naznaczone przez reformy edukacyjne ryzykiem nietrwałości, stanowią godne uwagi dokumenty nauczycielskiej twórczości. W badawczym do nich podejściu nie wystarczy historyczno-kulturowa perspektywa oceny ich roli w przemianach horyzontów i metod kształcenia polonistycznego. Trzeba również uwzględnić wymiar prakseologiczny: poświęcić uwagę twórczej roli wyobraźni dydaktycznej autorów w budowaniu podręcznika jako projektu określonych działań edukacyjnych. Pod tym względem można obecnie obserwować istotne zmiany w pojmowaniu relacji podręcznika wobec aktów „żywego nauczania”. Podręczniki autorstwa profesjonalnych badaczy literatury pozostają w zgodzie z tradycją uzupełniających działania lekcyjne zarysów wiedzy historycznoliterackiej o przedmiocie, ograniczających zobowiązania dydaktyczne do przestrzegania zasad jasności i przystępności przekazu oraz (niekiedy) zorientowanego na ucznia stylu narracji. Natomiast nowatorskie konstrukcje podręcznikowe, które powstają z inicjatywy zespołów nauczycielskich w bliskości szkolnego warsztatu, skupiają uwagę na projektowaniu narzędzia wspomagającego pracę nauczyciela i uczniów, sięgając do doświadczeń polonistów i apelując na różne sposoby do ich wyobraźni dydaktycznej. Wartość tak tworzonych konstrukcji podręcznikowych w wielu przypadkach równoważy się z osiągnięciami prac naukowych. Należy do nich sięgać w kształceniu polonistów.
„Być z przestrzenią” – uczyć o świecie. Edukacyjne aspekty interpretowania literatury najnowszej
Authors: Czyżak Agnieszka
Published: May 2020

Artykuł zawiera rozważania poświęcone prozie najnowszej i jej edukacyjnemu znaczeniu. Interpretacje tekstów Filipa Springera, Julii Fiedorczuk, Anny Janko czy Andrzeja Stasiuka mogą zostać uznane za przykłady działań analitycznych, pozwalających pokazywać powiązania między najnowszą literaturą a globalnymi oraz lokalnymi problemami trapiącymi ludzkie społeczności i zbiorowości. Spuścizna zwrotu przestrzennego we współczesnej humanistyce to zarazem wiele przemian, do których doszło nie tylko w ramach kulturowych dyskursów. Ważnym przekształceniom podległo postrzeganie innych obszarów badawczych, takich jak polityka, wzorce pamięci oraz ideologii, a także przemiany reguł wspólnotowego życia. Wzrost zainteresowania przestrzennym wymiarem doświadczeń jednostkowych i zbiorowych doprowadził do przeformułowania podstawowych zagadnień, takich jak język, podmiot, kultura, praktyka literacka i artystyczna, a także przedmiot badań oraz pozycja badacza w sferze nowych kompetencji.

Henryk Goldszmit/Janusz Korczaka czynnie uczestniczył w ruchu na rzecz praw dziecka, jednym z ruchów emancypacyjnych w pierwszych dekadach XX wieku. Wywodząc się z formacyjnych dlań środowisk: lekarskiego i edukacyjnego/obywatelskiego – których przedstawiciele zgłaszali ważne inicjatywy na rzecz dzieci – podejmował w międzywojniu różne działania, by upowszechniać postulaty uznania praw dzieci oraz społecznej odpowiedzialności za ich respektowanie. Jego autorską interpretację „naturalnych” praw dziecka dokumentuje m.in. opublikowany w 1928 roku konspekt (wprowadzenie oraz siedem grup tematycznych) wykładów, jakie Korczak wygłaszał w 2. połowie lat 20. w ramach państwowych kursów dla wychowawców placówek opiekuńczych.
Half mode substrate integrated waveguide based leaky wave antenna with low cross polarisation
Authors: Belwal Pravesh , Agrawal Rahul , Gupta Suresh Chandra
Published: May 2020

A half mode substrate integrated waveguide (HMSIW) based leaky wave antenna (LWA) featuring low cross-polarization is proposed in this paper. The umbrella-shaped slot (the combination of longitudinal and transverse slots) is etched on the top layer of HMSIW LWA to get the efficient broadside radiation. The scanning range is obtained from −47° to +30° in a frequency range of 8.3 to 15.1 GHz. The cross-polarization level for the LWA is around −10 dB at broadside. In order to improve the cross-polarization levels in HMSIW LWA, two antennas are placed face to face obtaining the balanced symmetry across the longitudinal axis. Both the simulated and measured results show that the antenna is able to scan continuously from backward to forward direction with a very good low cross-polarization level. The developed prototype is capable of continuous beam scan from −29° to +32° in an operating frequency band of 9.2 to 15 GHz with a maximum gain of 13.5 dBi. The measured cross-polarization level is −30 dB which is quite low for the main beam at the broadside direction.
Multimode T-junctions based on truncated Eaton lens
Authors: Badri Seyed Hadi , Gilarlue Mohsen Mohammadzadeh
Published: May 2020

Mode-division multiplexing (MDM) in silicon-on-insulator platform is an emerging technology to increase the channel number of a single wavelength carrier by the number of modes and consequently increase the transmission capacity of on-chip optical interconnects. We propose and theoretically demonstrate a multimode branching structure based on the truncated Eaton lens. The proposed T-junctions efficiently convert the higher-order modes into fundamental modes; therefore, they can be potentially employed to manipulate modes in MDM systems. The designed T-junctions are implemented by varying the guiding layer’s thickness on a silicon-on-insulator platform. The three-dimensional simulations verify that the proposed structures can split the TE2 (TE1) mode into the fundamental modes with an average transmitted power of 32% (47%) in a 1550–1600 nm bandwidth.
Metamaterials – from fundamentals and MEMS tuning mechanisms to applications
Authors: Chang Yuhua , Wei Jingxuan , Lee Chengkuo
Published: May 2020

Metamaterials, consisting of subwavelength resonant structures, can be artificially engineered to yield desired response to electromagnetic waves. In contrast to the naturally existing materials whose properties are limited by their chemical compositions and structures, the optical response of metamaterials is controlled by the geometrics of resonant unit cells, called “meta-atoms”. Many exotic functionalities such as negative refractive index, cloaking, perfect absorber, have been realized in metamaterials. One recent technical advance in this field is the active metamaterial, in which the structure of metamaterials can be tuned to realize multiple states in a single device. Microelectromechanical systems (MEMS) technology, well-known for its ability of reconfiguring mechanical structures, complementary metal-oxide-semiconductor (CMOS) compatibility and low power consumption, is perfectly suitable for such purpose. In the past one decade, we have seen numerous exciting works endeavoring to incorporate the novel MEMS functionalities with metamaterials for widespread applications. In this review, we will first visit the fundamental theories of MEMS-based active metamaterials, such as the lumped circuit model, coupled-mode theory, and interference theory. Then, we summarize the recent applications of MEMS-based metamaterials in various research fields. Finally, we provide an outlook on the future research directions of MEMS-based metamaterials and their possible applications.
Hybrid silicon photonic devices with two-dimensional materials
Authors: Li Jiang , Liu Chaoyue , Chen Haitao , Guo Jingshu , Zhang Ming , Dai Daoxin
Published: May 2020

Silicon photonics is becoming more and more attractive in the applications of optical interconnections, optical computing, and optical sensing. Although various silicon photonic devices have been developed rapidly, it is still not easy to realize active photonic devices and circuits with silicon alone due to the intrinsic limitations of silicon. In recent years, two-dimensional (2D) materials have attracted extensive attentions due to their unique properties in electronics and photonics. 2D materials can be easily transferred onto silicon and thus provide a promising approach for realizing active photonic devices on silicon. In this paper, we give a review on recent progresses towards hybrid silicon photonics devices with 2D materials, including two parts. One is silicon-based photodetectors with 2D materials for the wavelength-bands from ultraviolet (UV) to mid-infrared (MIR). The other is silicon photonic switches/modulators with 2D materials, including high-speed electro-optical modulators, high-efficiency thermal-optical switches and low-threshold all-optical modulators, etc. These hybrid silicon photonic devices with 2D materials devices provide an alternative way for the realization of multifunctional silicon photonic integrated circuits in the future.
Woran orientieren sich Einschätzungen zur Zumutbarkeit einer Beschäftigung? Befunde aus einer Vignettenbefragung
Authors: Osiander Christopher , Senghaas Monika
Published: May 2020

Dieser Beitrag geht der Frage nach, unter welchen Bedingungen die Ablehnung von Stellenangeboten durch Empfänger/-innen von Arbeitslosengeld als (un-)zumutbar gilt. Wir untersuchen dies anhand einer Vignettenstudie, in deren Rahmen wir Teilnehmenden an einer Online-Befragung mehrere Beschreibungen fiktiver Arbeitsloser vorlegen, die Stellenangebote erhalten und ablehnen. Empirisch zeigt sich, dass Abschläge im Vergleich zum früheren Einkommen dazu führen, dass Befragte eine Stelle als weniger zumutbar einschätzen. Dasselbe gilt, wenn das Anforderungsniveau niedriger ist. Außerdem wird Älteren eher zugestanden, ein Stellenangebot abzulehnen als Jüngeren; umgekehrt ist es bei Personen, die bereits in der Vergangenheit arbeitslos waren. Die Zahl der verfügbaren Stellen und die Art der angebotenen Tätigkeit (Zeitarbeit, Befristung) beeinflussen das Urteil hingegen nicht.

For more than four decades, a strange story has circulated both inside and outside of the academy concerning a 1970s experiment in which foods dyed strange colors were served under “special” lighting that made them appear normal. When the true colors of the meal were revealed, the experimental subjects became agitated and ill. This article explores the origins of the story and its proliferation in prominent newspapers, magazines, and peer-reviewed journals, and speculates as to the nature of its appeal and endurance.
RSU-1 Maintains Integrity ofCaenorhabditis elegansVulval Muscles by Regulating α-Actinin

Published: May 2020

Egg-laying behavior in Caenorhabditis elegans is a well-known model for investigating fundamental cellular processes. In egg-laying, muscle contraction is the relaxation of the vulval muscle to extrude eggs from the vulva. Unlike skeletal muscle, vulval muscle lacks visible striations of the sarcomere. Therefore, vulval muscle must counteract the mechanical stress, caused by egg extrusion and body movement, from inducing cell-shape distortion by maintaining its cytoskeletal integrity. However, the underlying mechanisms that regulate the cellular integrity in vulval muscles remain unclear. Here, we demonstrate that C. elegans egg-laying requires proper vulval muscle 1 (vm1), in which the actin bundle organization of vm1 muscles is regulated by Ras suppressor protein 1 (RSU-1). In the loss of RSU-1, as well as RasLET-60 overactivation, blister-like membrane protrusions and disorganized actin bundles were observed in the vm1 muscles. Moreover, RasLET-60 depletion diminished the defected actin-bundles in rsu-1 mutant. These results reveal the genetic interaction of RSU-1 and RasLET-60in vivo. In addition, our results further demonstrated that the fifth to seventh leucine-rich region of RSU-1 is required to promote actin-bundling protein, α-actinin, for actin bundle stabilization in the vm1 muscles. This expands our understanding of the molecular mechanisms of actin bundle organization in a specialized smooth muscle.
Selective Loss of Diversity in Doubled-Haploid Lines from European Maize Landraces
Authors: Zeitler Leo , Ross-Ibarra Jeffrey , Stetter Markus G
Published: May 2020

Maize landraces are well adapted to their local environments and present valuable sources of genetic diversity for breeding and conservation. But the maintenance of open-pollinated landraces in ex-situ programs is challenging, as regeneration of seed can often lead to inbreeding depression and the loss of diversity due to genetic drift. Recent reports suggest that the production of doubled-haploid (DH) lines from landraces may serve as a convenient means to preserve genetic diversity in a homozygous form that is immediately useful for modern breeding. The production of doubled-haploid (DH) lines presents an extreme case of inbreeding which results in instantaneous homozygosity genome-wide. Here, we analyzed the effect of DH production on genetic diversity, using genome-wide SNP data from hundreds of individuals of five European landraces and their related DH lines. In contrast to previous findings, we observe a dramatic loss of diversity at both the haplotype level and that of individual SNPs. We identify thousands of SNPs that exhibit allele frequency differences larger than expected under models of neutral genetic drift and document losses of shared haplotypes. We find evidence consistent with selection at functional sites that are potentially involved in the diversity differences between landrace and DH populations. Although we were unable to uncover more details about the mode of selection, we conclude that landrace DH lines may be a valuable tool for the introduction of variation into maize breeding programs but come at the cost of decreased genetic diversity.

Authors: Santer Mario , Uecker Hildegard
Published: May 2020

Bacteria often carry “extra DNA” in the form of plasmids in addition to their chromosome. Many plasmids have a copy number greater than one such that the genes encoded on these plasmids are present in multiple copies per cell. This has evolutionary consequences by increasing the mutational target size, by prompting the (transitory) co-occurrence of mutant and wild-type alleles within the same cell, and by allowing for gene dosage effects. We develop and analyze a mathematical model for bacterial adaptation to harsh environmental change if adaptation is driven by beneficial alleles on multicopy plasmids. Successful adaptation depends on the availability of advantageous alleles and on their establishment probability. The establishment process involves the segregation of mutant and wild-type plasmids to the two daughter cells, allowing for the emergence of mutant homozygous cells over the course of several generations. To model this process, we use the theory of multitype branching processes, where a type is defined by the genetic composition of the cell. Both factors—the availability of advantageous alleles and their establishment probability—depend on the plasmid copy number, and they often do so antagonistically. We find that in the interplay of various effects, a lower or higher copy number may maximize the probability of evolutionary rescue. The decisive factor is the dominance relationship between mutant and wild-type plasmids and potential gene dosage effects. Results from a simple model of antibiotic degradation indicate that the optimal plasmid copy number may depend on the specific environment encountered by the population.

Breeding colonies of Storm-petrels (family Hydrobatidae) are poorly known and can be difficult to find because they typically nest on islands in crevices and burrows inside caves. In the past decade, some breeding locations of the Wedge-rumped Storm-petrel (Hydrobates tethys kelsalli) have been reported on islands off central Peru and northern Chile. Here we report the northernmost breeding colony of this subspecies from Isla Foca, northern of Peru. In April 2006 we found 28 nests, of which 46% had chicks and 54% had eggs. Nests consisted of small holes in the rock with no nest material used for construction. Nesting season coincided with that of other reproductive zones found on the Peruvian coast. These results contribute to the knowledge of the distribution of reproductive colonies of this subspecies on the Peruvian coast.

Milk of calcium is a viscous colloidal suspension of calcium salts that forms in dilated cysts or cavities. We present, for the first time in literature, a toddler with isolated milk of calcium and treated with a conservative approach. A boy with a history of one urinary tract infection and recurrent fever without vesicoureteral reflux showed at the age of 14 months a left obstructive staghorn stone. Because of absent function of the left kidney at mercapto acetyl tri glycine scintigraphy, a JJ stent was positioned with a leak of whitish material immediately after the stent positioning. Renal scintigraphy performed 1 month later revealed a partial resumption in renal function (18%). When he was 18 months old, the child suffered episodes of acute pain with inconsolable crying, unresponsive to paracetamol administration. Ultrasound assessment revealed left pelvic dilation (anterior-posterior diameter of 18 mm), suspended echogenic debris in the bladder, and dilated left distal ureter with particulate matter. These episodes of acute pain were followed by expulsion of numerous soft formations and emission of greenish urine. Both urine culture at the admission and culture on the greenish urines were sterile. After the expulsion of the soft formations, pain episodes stopped. The diagnosis of milk of calcium stone was made. With this case, we highlight a condition that can be easily diagnosed (if known) because the morphology of the expelled material is pathognomonic. Diagnosing it could avoid unnecessary treatments (ie, extracorporeal shockwave lithotripsy) and support a conservative approach (ie, stent positioning).

Yen Phu rare earth deposit covering over 0.7 km2 in Yen Bai province, Northern Vietnam contains heavy elements bearing radioactive materials. The area has been studied based on data of several thousand meters of boreholes, 2000 m3 of trenches, shallow shafts, and thousands of rock samples. This article shows the results of radioactive measurements and analysis by regular grids before and after exploration activities. The investigated area has been divided into two different subunits characterized by different levels of the radiation dose. It can be observed that after the exploration process, equivalent dose increases by 1.2 mSv/y and reaches recent value of 9.9 mSv/y. This value is still below the acceptable value according to the ICRP regulations, however, it should be noted that the increase can exceed the critical value during industrial production and processing. Therefore it will be necessary to undertake investigation and implementation of radioactive monitoring system to maintain the safety for people.

The results of synchronous detection of the emission of various components of the electromagnetic and acoustic fields obtained under conditions of low industrial interference and a high level of microseismicity are investigated. To compensate electromagnetic radiation of lithospheric origin, a compensation method was used. The signal loop antenna, recording a mixture of signals of lithospheric and atmospheric-thunderstorm origins, was used as a magnetic core of a steel casing of the borehole. The compensating signal was recorded using an antenna, the receiving coil of which was identical to the coil of the signal antenna. The measurements were carried out in the seismically active region of Russia (the Kamchatka peninsula, the Paratun hydrothermal deposit) at the intersection of the sublatitudinal and submeridional fault zones. Methods for analyzing registration data of non-stationary processes are considered using the example of acoustic-electromagnetic emission of the lithosphere, the electromagnetic component of which is a component of the natural electromagnetic field of the Earth. Their characteristics are estimated and a statistical model is proposed that uses nested semi-Markov processes and finite atomic functions. Observations of geophysical electromagnetic fields, in addition to useful information about the emission processes, contain interference, mainly of technogenic origin. They are especially strong in downhole measurements when a well casing is used as the receiving antenna. These interferences significantly impede the allocation of useful information. The possibility of using bleaching filters to increase the contrast of observation of useful signals of lithospheric origin against their background is considered.
