Le magazine, support originel de la photographie japonaise dans les années 1960-1970
Authors: Froger Lilian 
Published: October 2020

Les années 1960 et 1970 sont généralement considérées comme l’âge d’or de la photographie japonaise, période pendant laquelle débutent les carrières de Tōmatsu Shōmei, Nakahira Takuma, Moriyama Daidō, ou encore d’Araki Nobuyoshi. Si les musées font désormais l’acquisition de certains de leurs tirages, l’essentiel de leur production photographique a toujours été destiné à la publication. Le livre de photographies japonais a quant à lui fait l’objet de beaucoup d’attention depuis une quinzaine d’années, mettant en lumière un pan méconnu de l’histoire de la photographie japonaise. Il reste cependant à appréhender un autre acteur majeur de cette histoire : le magazine. En effet, qu’il prenne la forme de revues indépendantes ou de périodiques à grand tirage, le magazine sert au Japon à la fois de vecteur de diffusion de la photographie mais aussi de support de création et de réflexion à part entière, contribuant pleinement à partir de la fin des années 1960 à l’affirmation d’une pensée de l’image photographique sous forme de séquence.
Inflammation Unrestrained by SIRPα Induces Secondary Hemophagocytic Lymphohistiocytosis Independent of IFN-γ
Authors: Kidder Koby , Bian Zhen , Shi Lei , Liu Yuan 
Published: October 2020

Abstract
A hallmark of secondary hemophagocytic lymphohistiocytosis (sHLH), a severe form of cytokine storm syndrome, is the emergence of overactivated macrophages that engulf healthy host blood cells (i.e., hemophagocytosis) and contribute to the dysregulated inflammation-driven pathology. In this study, we show that depleting SIRPα (SIRPα−/−) in mice during TLR9-driven inflammation exacerbates and accelerates the onset of fulminant sHLH, in which systemic hemophagocytosis, hypercytokinemia, consumptive cytopenias, hyperferritinemia, and other hemophagocytic lymphohistiocytosis hallmarks were apparent. In contrast, mice expressing SIRPα, including those deficient of the SIRPα ligand CD47 (CD47−/−), do not phenocopy SIRPα deficiency and fail to fully develop sHLH, albeit TLR9-inflamed wild-type and CD47−/− mice exhibited hemophagocytosis, anemia, and splenomegaly. Although IFN-γ is largely considered a driver of hemophagocytic lymphohistiocytosis pathology, IFN-γ neutralization did not preclude the precipitation of sHLH in TLR9-inflamed SIRPα−/− mice, whereas macrophage depletion attenuated sHLH in SIRPα−/− mice. Mechanistic studies confirmed that SIRPα not only restrains macrophages from acquiring a hemophagocytic phenotype but also tempers their proinflammatory cytokine and ferritin secretion by negatively regulating Erk1/2 and p38 activation downstream of TLR9 signaling. In addition to TLR9 agonists, TLR2, TLR3, or TLR4 agonists, as well as TNF-α, IL-6, or IL-17A, but not IFN-γ, similarly induced sHLH in SIRPα−/− mice but not SIRPα+ mice. Collectively, our study suggests that SIRPα plays a previously unappreciated role in sHLH/cytokine storm syndrome pathogenesis by preventing macrophages from becoming both hemophagocytic and hyperactivated under proinflammation.
Uncertainty Analysis for the Measurement of Oil-Water Flow Parameters, Part II: Pressure Drop
Authors: Abubakar A. 
Published: October 2020

The need to ensure qualitative and reliable measurement of pressure drop of the oil-water flow cannot be over emphasized. In this regard, this study focused on the investigation of uncertainty in the measurement of pressure drop of oil-water flow in different acrylic pipe inclinations (0, +5ᴼ, +10ᴼ and -5ᴼ) and diameters (30.6-, 55.7- and 74.7-mm ID). The working fluids were tap water and mineral-based hydraulic oil (Shell Tellus S2 V 15), with medium viscosity and density of 24 cP and 872 kgm-3 respectively while the interfacial tension between the water and the oil was 12.9 mN/m at 25 ᴼC. The selected flow conditions were 0.5 and 1.0 m/s mixture velocities each at 0.1, 0.5 and 0.9 input water volume fractions. The repeatability, accuracy of the pressure transmitter, flow rate of the oil-water mixture and holdup (particularly for the inclined flow) were the sources of errors in the measurement of the pressure drop. The results showed that the average relative uncertainties in the pressure drop in 30.6-mm ID pipe were ±4.6 %, ±10.8 %, ±11.2 % and ±10.8 % in the 0ᴼ, +5ᴼ, +10ᴼ and -5ᴼ inclined flows respectively. Similarly, the average relative uncertainties in the pressure drop in the horizontal 55.7-mm and 74.7-mm ID pipes were ±5.7 % and ±7.5 % respectively. The largest contribution to the uncertainty in the pressure drop came from the flow rate and water holdup in the horizontal and inclined pipes respectively. The least contribution in both horizontal and inclined pipes came from the accuracy of the pressure transmitter.

Published: October 2020

A study was carried out to determine the antibiotic sensitivity pattern of bacteria isolates associated with selected waste dumpsites in Akure metropolis, Nigeria. Results revealed that the total plate count of bacteria ranged from 1.3×105 cfu/g to 3.0×106 cfu/g. Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi, Streptococcus faecalis, Shigella dysenteriae, Escherichia coli, Micrococcus luteus, Serratia marcescens, Clostridium botulinum were the isolated bacterial species. The temperature and pH values ranged from 26˚C to 28˚C and 5.68 to 6.48 respectively. Pseudomonas aeruginosa and Serratia showed susceptibility to antibiotics while Micrococcus luteus exhibited resistance to the antibiotics. Some of these isolated bacteria are pathogenic and thus, poses potential threat to the local inhabitant of the area. Therefore, proper waste management practices must be put in place to avoid environmental health hazards.

En la evaluación de la operación de la prensa de tornillo se usó una prensa hidráulica, calibrada para trabajar a una presión de 185 p.s.i./m2 for 1 minute. El residuo sólido de la prensa de tornillo se sometió a la acción de la prensa hidráulica para extraer la leche de coco residual. Los resultados de los experimentos indican un aumento gradual en la eficiencia del proceso de extracción de leche de coco, según se aumenta la presión en el cono-válvula de 60 a 180 lbs./pulg.2, notándose, sin embargo, un cambio más pronunciado entre 60 y 100 lbs. de presión. El aumento en la eficiencia a una velocidad de 17.5 r.p.m. fluctúa entre 3.5 y 6.5 por ciento. En el funcionamiento de la prensa de tornillo, es la capacidad la característica que más se afecta con los cambios en la velocidad del tornillo alimentador. Esta varía de 2,720 a 3,160 lbs. por hora a una velocidad de 17.5 r.p.m.; de 1,700 a 1,800 lbs. a 12.5 r.p.m.; y fluctúa alrededor de 1,800 lbs. a una velocidad de 8.5 r.p.m. Como resultado del estudio efectuado se recomiendan las siguientes condiciones para el funcionamiento de la prensa de tornillo en la extracción de leche de coco: una velocidad de 17.5 r.p.m. en el tornillo sinfín; 100 libras de presión por pulgada cuadrada en el cono-válvula; y la molienda de la pulpa de coco en un molino de martillos equipado con un cedazo Núm. 4 (10 perforaciones de 0.25 pulgada/pulg.2 de diámetro de superficie).
Effect of the Nematocides Nemagon and DD on Mineralization, Nitrification, Soil Microbial Population, and Soil Fertility Status of Two Tropical Soils
Authors: Dubey H. D. , Riera A. , Rodríguez R. L. 
Published: October 2020

Nitrification was inhibited in an acid soil by 60 p/m or more of Nemagon; the NH4+ oxidizing bacteria being affected but not the Nitrobacter, as NO2- accumulation was not observed. Nitrogen mineralization was not affected even at 20,000 p/m of Nemagon and an increase in available P, Mn, and a rise in pH occurred in both acid and alkaline soils. Extractable zinc increased in the acid soil. DD was extremely toxic to the nitrifying bacteria; much more so than Nemagon. It inhibited NH4+ oxidizing bacteria but not the Nitrobacter. Nitrogen mineralization was progressively depressed with increasing levels of DD. It resulted in a decrease in pH and extractable P. Mn increased in both the acid and alkaline soils, whereas the effect on Fe and Mg were inconsistent. Bacteria, actinomycetes and fungi were suppressed drastically. At lower levels bacterial population was increased, indicating a possible role in detoxification of DD.

The Differing Shades of Redface: The Evolving Image of Native Americans in Hollywood Comedies
Authors: Manning Adrian S. A. 
Published: October 2020

ABSTRACT
Native Americans have consistently been misrepresented through humor directed at them in Hollywood film and television. This article explores how Hollywood humor stereotypes and distorts images of the Native American “other.” Relying on Louis Giannetti's genre development theory, which postulates that film genres evolve through four distinct stages (primitive, classical, revisionist, and parodic), it constructs a racial stereotype development theory to show how racial stereotypes similarly evolve and give rise to a fifth (satirical) stage of development. It also demonstrates that racial humor perpetuates further racial inequalities until the satirical stage, during which stereotypes are purposely challenged using the corrective strategies of satire.

AbstractSampling two Onslow Bay sites bi-weekly from 1975–2010 using semi-balloon otter trawls 950 times collected two species of butterfly rays Gymnura altevala and Gymnura micrura: 37 were G. altevala and 244 were G. micrura. All but one male G. altevala were collected at the inshore site. Most specimens of both species were less than 1,000 mm disc width (DW). Most specimens were collected in April and October. Both species remain infrequent visitors of North Carolinian waters.
Four New Land Snail Species from the Southern Appalachian Mountains
Authors: Dourson Daniel C. 
Published: October 2020

AbstractFour new species of land snails Carychium arboreum, Fumonelix langdoni, Fumonelix cherohalaensis, and Fumonelix roanensis are described from the southern Appalachian Mountains located in North Carolina and Tennessee, U.S.A. Carychium arboreum is presently known from Swain County, North Carolina. Fumonelix langdoni is known only from along the Appalachian Trail flanking Monroe County, Tennessee and Swain County, North Carolina and is endemic to the Great Smoky National Park. Fumonelix cherohalaensis appears restricted to elevations above 1,372 m in northern hardwood forests along the Cherohala Scenic Highway located in Graham County, North Carolina and Monroe County, Tennessee. Fumonelix roanensis is currently known from Roan Mountain in Mitchell County, North Carolina where it is found in upper elevation northern hardwood and spruce/fir forests.
Land Snails of Selected Rare High Elevation Forests and Heath Balds of the Great Smoky Mountains National Park
Authors: Dourson Daniel C. , Langdon Keith 
Published: October 2020

Abstract
Selected high elevation forests and heath balds of the Great Smoky Mountains National Park (GSMNP) between Newfound Gap and Thunderhead Mountain were comprehensively sampled for the first time. Thirty-three species including one new species Fumonelix langdoni (Dourson) were documented occurring at elevations between 1,372 m to 2,012 m. Two previous land snail inventories in the park by Thompson (1981) and Dourson (2005) added sixteen species, bringing the total land snail fauna to forty nine species living above 1,372 m within park boundaries. Overall species richness declines with elevation yet numbers of snails appear to change little with increasing altitude. Heath balds were comparably rich sites for gastropods, Vitrinizonites latissimus (Lewis) being the most frequently observed land snail. Mesodon altivagus, (Pilsbry) and Fumonelix jonesiana (Archer) both documented during the survey are of global importance, a result of an exceptionally restricted range within the park. One ambiguous species in the genus Fumonelix (Polygyridae) is discussed and likely represents new taxa. Appalachina chilhoweensis (J. Lewis) was found at 1,666 m, representing the highest elevation the species has been documented to date.

Output feedback tracking control for rigid body attitude via immersion and invariance angular velocity observers
Authors: Xia Dongdong , Yue Xiaokui , Wen Haowei 
Published: October 2020

SummaryA novel immersion and invariance (I&I) angular velocity observer is presented for the attitude tracking control of a rigid body with the lack of angular rate. Global exponential convergence of angular velocity estimate errors are guaranteed by an innovative filter design for the estimates' Euclidean norm. The proposed method requires fewer filter states compared with existing I&I angular velocity observer designs, which achieves a simpler closed‐loop structure (dynamic reduction). The observer synthesis and convergence are independent of the control torque, which leads to much convenience in establishing “separation property” when combining a proportional‐derivative attitude tracking controller driven by angular velocity estimates. A rigorous stability analysis is provided to ensure the (almost) global asymptotic convergence of the overall closed‐loop tracking errors, and several numerical simulations are carried out to demonstrate the effectiveness of the combined implementation of proposed angular velocity observer and full‐state feedback attitude tracking controller.
Dome‐Patterned Metamaterial Sheets

Published: October 2020

AbstractThe properties of conventional materials result from the arrangement of and the interaction between atoms at the nanoscale. Metamaterials have shifted this paradigm by offering property control through structural design at the mesoscale, thus broadening the design space beyond the limits of traditional materials. A family of mechanical metamaterials consisting of soft sheets featuring a patterned array of reconfigurable bistable domes is reported here. The domes in this metamaterial architecture can be reversibly inverted at the local scale to generate programmable multistable shapes and tunable mechanical responses at the global scale. By 3D printing a robotic gripper with energy‐storing skin and a structure that can memorize and compute spatially‐distributed mechanical signals, it is shown that these metamaterials are an attractive platform for novel mechanologic concepts and open new design opportunities for structures used in robotics, architecture, and biomedical applications.
Interrelationships between water use efficiency and light use efficiency in four row crop canopies
Authors: Kukal Meetpal S. , Irmak Suat 
Published: October 2020

AbstractQuantitative evidence of light use efficiency (LUE) controls on water use efficiency (WUE) is lacking, especially comparatively across row crops. Field research experiments (2016–2018) were set up for maize (Zea mays L.), soybean [Glycine max (L.) Merr.], sorghum [Sorghum bicolor (L.) Moench], and winter wheat (Triticum aestivum L.), under optimal growth conditions in dry sub‐humid conditions. Overall, LUE was able to explain 52% of variance in WUE, and were related as WUE = 1.73 LUE, although crop‐specific variation was observed. Highest sensitivity of WUE to changes in LUE was found in sorghum, followed by soybean, winter wheat, and maize. Evapotranspiration per unit light absorbed by crop canopy, which is a measure of canopy conductance (gc) ranged from a minimum of 0.45 kg H2O MJ−1 in sorghum to a maximum of 0.68 kg H2O MJ−1 in maize. Slopes of WUE vs. LUE relationship were limited by energy‐limited upper ceiling of latent heat of vaporization and characterized distribution of absorbed energy into latent heat of vaporization and sensible heat. Vapor pressure deficit (VPD) accounted for 41% of variability in the WUE vs. LUE relationship, and the relationship was subject to change with VPD conditions higher or lower than 0.85 kPa. Seasonal evolution of crop‐specific gc was modeled and communicated as a function of heat accumulation during the growing season. The research findings contribute to quantification of critical parameters that bridge water and light use efficiency, and better understanding of the resource use in C3 and C4 agricultural row crops.
Effect of curing bath conditions on the morphology and structure of poly(high internal phase emulsion) fibers
Authors: Gong Xuehui , Zhao Boran , Manas‐Zloczower Ica , Feke Donald L. 
Published: October 2020

AbstractThe potential of polymerizing high internal phase emulsions (HIPEs) as a simple and environmentally friendly technique to fabricating porous fibers has been demonstrated. Porous fibers with varied microstructure can be created through manipulation of the composition of the curing bath in which the HIPEs are polymerized. Osmotic pressure effects, activated through setting the electrolyte concentration in the curing bath different than that of the aqueous phase within the HIPE, can be used to alter the void size near the periphery of the fiber. Adding initiator to the bath triggers a relatively faster polymerization reaction at the HIPE‐bath interface, which can lock‐in the microstructure before other kinetic effects occur. Including surfactant in the curing bath can affect the HIPE stability and thus the fiber morphology. Porous fibers exhibiting a variety of surface morphologies, ranging from completely closed surfaces to those with 30‐μm voids, have been produced. This new approach enables the possibility of designing porous fibers for different applications via simple manipulation of curing‐bath conditions.
Galleria mellonellalarvae fat body disruption (Lepidoptera: Pyralidae) caused by the venom ofHabrobracon brevicornis(Hymenoptera: Braconidae)

Published: October 2020

AbstractThe ability ofHabrobracon brevicornisvenom to elevate the nutritional suitability of a host by affecting the host larvae fat body condition was studied. To understand whetherH. brevicorniscrude venom impacts the host biochemical profile, the concentrations of total lipids and main sugars in the host larvae lymph were analyzed. All measurements were carried out during the first 3 days after envenomation. A significant increase in the lipid level was fixed only on the second day after envenomation. A significant increase in the total trehalose count was detected during all 3 days, while a significant increase in glucose concentration was noted only on the first day. Well‐observed disruptions were fixed in thin and semithin sections of theG. mellonellalarval fat body starting from the second day after envenomation. Significant increases in both phospholipase A2and C enzyme activity as well as acid proteases were detected in the wax moth fat body after envenomation during all experimental times. At the same time, imbalances in the antioxidant system, including changes in the activities of superoxide dismutase, peroxidases, catalase, and glutathione‐S‐transferase, were detected. The reliable increase in the expression of the gene encoding Hsp70 was fixed both for 24 and 48 h after envenomation, while a reliable increase in the expression of the gene encoding inhibitor of apoptosis protein was detected only 24 h after wax moth larvae envenomation. Considering the absence of DNA fragmentation, the imbalance in the “ROS/antioxidants” system, and the increased activity of phospholipases and acid proteases in the fat body cells from envenomated wax moth larvae, we can hypothesize that the fat body disruption occurs in a necrotic manner. The results of the work expand the knowledge about the biochemical aspects of interaction between ectoparasitoids and their hosts
