Dataset supporting the publication "Mean flow of turbulent boundary layers over porous substrates"
No full textThis dataset supports the following publication:
L. B. Esteban, E. Rodriguez-Lopez, M. A. Ferreira and B. Ganapathisubramani, "Mean flow of turbulent boundary layers over porous substrates", Phys. Rev. Fluids, 2022
DOI: 10.1103/PhysRevFluids.00.004600
This dataset contains .mat files which has all the mean velocity profiles as well as the information on other scaling quantities such as skin-friction velocity, boundary layer thickness, kinematic viscosity and free stream velocity to obtain the different plots presented in the paper.
The data is presented in three different .mat files, one for each of the three different porous/permeable substrates examined in the study.
Measurements of turbulent boundary layer flow over all three porous substrates (10PPI, 45PPI and 90PPI) with two different thicknesses (3mm and 15 mm) have been performed using hot-wire anemometry and skin-friction drag-balance. The data presented provides profiles of mean velocity obtained using hot-wire measurements for the three cases at three different freestream velocities (10 m/s, 18 m/s and 26 m/s).
The specifics of the data is self-evident upon using the data from the three different mat files. </span
Electrocatalysts for oxygen evolution reaction : Innovative investigation methods for screening and mechanisms
No full textThe oxygen evolution reaction is one of the most important electrochemical phenomena, especially for both its implications in energy conversion devices (electrochemical and photoelectrochemical water splitting) and for its importance in life science.
Quite recently, new investigative methods based on the use of microelectrodes (the scanning electrochemical microscope and the cavity-microelectrode1,2) have opened new paths for understanding fundamental mechanisms in electrocatalysis in general, and for oxygen evolution reaction in particular. At the same time, new methods for the rapid screening and for the visualization of the experimental data have been developed and applied to different materials.
The rapid screening methods are based on the use of SECM, in the sg-tc mode, by adopting the innovative “shielded tip” approach3, or by applying a pulsed potential profile at the substrate. With these methods, mixtures of SnO2-IrO2 were studied.
The selection of the right material for practical applications also implies a knowledge of the candidates’ behaviour under different conditions (applied potential, pH). In this case, the collection of experimental could be in vain without an effective method of displaying them. For this reason, a new kind of 3D diagram, the dynamic potential/pH plot4 (DPPDs) is proposed for different materials.

Aaron Lopez papers, undated, 1752-1794, 1846, 1852, 1953.
No full textContains approximately 6800 manuscripts arranged chronologically by year for years 1752-1794. Approximately 100 are letters received or written by Lopez, his partner and father-in-law, Jacob Rodriguez Rivera, members of his family and company, and commercial agents pertaining to business activities and sailing orders for the captains of various ships. Several also refer to personal matters and acquaintances, including a series of six letters from Silas Cooke of White Hall (Middletown), R.I., to Aaron Lopez, asking his aid in returning a run-away slave (1776). The great majority of the collection consists of account records, bills of sale, orders, shipping agreements, lists of sailors on the various ships, repair records and cargo invoices. Of particular interest are a receipt for payment of a half-year's subscription to the "tzedakah" of Congregation Nefutzei Israel, Newport (1755) and several documents that reveal Lopez as a supplier of kosher meat and other religious articles to people in various parts of the colonies, Surinam, and Jamaica. Also included in this group are copies of sailing lists, documents pertaining to Lopez's naturalization which shed light upon the status of a Jew applying for citizenship in Massachusetts and a check to Lopez from the United States government for a loan made during the Revolutionary War (1779).684 typewritten and carbon copies of various Lopez papers and documents (originals are in the Newport Historical Society) have been added to the collection.Parts of the collection were donated by Lee M. Friedman, Dr. A.F. Mendes, A.S.W. Rosenbach, Samuel Oppenheim, and the Elsie O. and Philip D. Sang Foundation.far031
Immunohistopathological findings in the lungs of calves naturally infected with Mycoplasma bovis
No full textHistology and immunohistochemistry were used to analyse the lesions and distribution of Mycoplasma bovis antigen in the lungs of 18 naturally infected calves. Microscopic examination of pneumonic lungs revealed two distinct patterns of necrosis and inflammation. The first pattern was observed in six of 18 (33.3%) calves in which microscopic lesions were characterized by large irregular areas of coagulative necrosis surrounded by a dense zone of degenerated neutrophils. Moderate amounts of mycoplasmal antigen were in the centre and periphery of these necrotic foci and, to a lesser extent, in mononuclear cells of the peribronchial lymphoid tissue. The second pattern was observed in 18 of 18 (100%) calves and consisted of rounded foci of caseous necrosis composed by granular eosinophilic material surrounded by a rim of granulation tissue. Large amounts of M. bovis antigen were detected in the centre and periphery of these necrotic foci and, to a lesser extent, in the peribronchial lymphoid tissue, and alveolar and interstitial macrophages. It was concluded that both caseous and coagulative necrosis of the lung parenchyma was primarily caused by M. bovis. Infection with M. bovis should be suspected in bovine necrotic bronchopneumonia, particularly in cases in which the pulmonary necrosis is part of a pyogranulomatous inflammation centred around airways. The pattern of caseous necrosis with pyogranulomatous inflammation is characteristic of M. bovis infection while the pattern of coagulative necrosis is similar to and must be differentiated from Mannheimia haemolytica and Haemophilus somnus infection.PT: J; CR: ADEGBOYE DS, 1995, J VET DIAGN INVEST, V7, P261 ADEGBOYE DS, 1995, J VET DIAGN INVEST, V7, P333 BENNETT RH, 1977, AM J VET RES, V38, P1731 BOOTHBY JT, 1988, CORNELL VET, V76, P188 BOUGHTON E, 1979, VET B, V49, P377 BRICE N, 2000, VET REC, V146, P643 BUCHVAROVA Y, 1989, ARCH EXP VET MED, V43, P685 DUNGWORTH DL, 1993, PATHOLOGY DOMESTIC A, P539 GEARY SJ, 1981, SCIENCE, V212, P1032 GOURLAY RN, 1985, RES VET SCI, V38, P377 GOURLAY RN, 1989, VET REC, V124, P420 HAINES DM, 1991, J VET DIAGN INVEST, V3, P101 HAINES DM, 2001, CAN VET J, V42, P857 HEWICKERTRAUTWEIN M, 2002, VET REC, V151, P699 KINDE H, 1993, J VET DIAGN INVEST, V5, P194 LOPEZ A, 1986, AM J VET RES, V47, P1283 LOPEZ A, 2001, SPECIAL VET PATHOLOG, P125 LOPEZ A, 2002, 18 PAN AM C VET SCI NICHOLAS RAJ, 2003, RES VET SCI, V74, P105 POTGIETER LND, 1995, VET CLIN N AM-FOOD A, V11, P501 RODRIGUEZ F, 1996, J COMP PATHOL, V115, P151 SHAHRIAR FM, 2002, CAN VET J, V43, P863 SLAUSON DO, 1990, MECH DIS TXB COMP GE THOMAS A, 2002, VET RES COMMUN, V26, P333; NR: 24; TC: 1; J9: J VET MED A-PHYSIOL PATHOL CL; PG: 5; GA: 818KGSource type: Electronic(1
Recent developments on the rapid screening of electrocatalysts by scanning electrochemical microscopy
No full textScanning Electrochemical Microscopy is a scanning probe technique which is
becoming a leading electrochemical technique. The possibility of using a movable
microelectrode which can be scanned over a surface is one of the most attractive
features. In turn, the substrate can assume different natures, from biological systems to
electrocatalytic surface, from photoactive materials to nanostructured textures, thus
making the technique extremely flexible.
In the most recent years, SECM is being applied to study libraries of materials useful as
electrocatalysts or photoelectrocatalysts in energy conversion devices
1-3
.
In this work, recent results on the rapid screening of electrochemical activity of
material libraries toward the oxygen evolution/reduction reactions are shown and
discussed.
The effectiveness of these methods is proved by digital simulations.
Both methods were applied on model mixtures based on the Ir-O system, considered as
promising materials for the preparation of operative devices.
Experimental results obtained by SECM are confirmed by voltamperometric and
physico-chemical techniques.

Cryptodacus bernardoi is known only from Colombia in Cundinamarca department in the municipios of Anolaima and Guaduas at middle altitudes on the west side of the eastern cordillera. Host plant. Three of the paratypes were reared from tiny fruits of Phoradendron sp. near piperoides (Kunth) Trel. (Figs. 43, 44), which was found parasitizing the upper part of a Psidium guajava L. shrub. This host plant is locally known by the common names “muérdago”, “matapalo”, “injerto” and “pajarito”. Phoradendron is variously classified in the Santalaceae or Viscaceae. The only previous host data for Cryptodacus was the single record of C. silvai Lima from fruit of “herva de passarinho” (Loranthus sp.) from southern Brazil (Lima 1947). The Loranthaceae, Santalaceae (and Viscaceae, when recognized as distinct from Santalaceae) belong to the order Santalales, many of which are parasitic plants. Etymology. This species is named for José Bernardo Rodríguez, father of the senior author. Comments. This species runs with difficulty in the keys of Norrbom (1994) and Norrbom & Korytkowski (2008). C. bernardoi may be most closely related to C. lopezi Norrbom, which has a similar aculeus, or it may belong to a clade along with that species and C. tau and trinotatus. The abdominal pattern is intermediate between those species, which have a distinct medial brown vitta or pair of vittae bordered by white or yellow sublateral areas on at least tergite 5 and female tergite 6, and the predominantly brown pattern in other species. In C. bernardoi the bands on tergites 4–5 in the male and 5–6 in the female may be interrupted. These four species also have the head mostly or entirely yellow posteriorly. The males were described only for C. bernardoi, C. obliquus, C. parkeri and C. tau.Published as part of Rodriguez, Pedro Alexander, Rodriguez, Erick J., Norrbom, Allen L. & Arévalo, Emilio, 2016, A new species and new records of Cryptodacus (Diptera: Tephritidae) from Colombia, Bolivia and Peru, pp. 276-290 in Zootaxa 4111 (3) on pages 277-279, DOI: 10.11646/zootaxa.4111.3.5, http://zenodo.org/record/26487
