Abstract
Introduction Compensatory articulations are speech disorders due to the attempt of the individual with cleft palate/velopharyngeal dysfunction to generate intraoral pressure to produce high-pressure consonants. Speech therapy is the indicated intervention for their correction, and an intensive speech therapy meets the facilitating conditions for the correction of glottal stop articulation, which is the most common compensatory articulation.
Objective To investigate the influence of an intensive speech therapy program (ISTP) to correct glottal stop articulation in the speech of individuals with cleft palate.
Methods Speech recordings of 37 operated cleft palate participants of both genders (mean age = 19 years old) were rated by 3 experienced speech/language pathologists. Their task was to rate the presence and absence of glottal stops in the 6 Brazilian Portuguese occlusive consonants (p, b, t, d, k, g) distributed within several places in 6 sentences.
Results Out of the 325 pretherapy target consonants rated with glottal stop, 197 (61%) remained with this error, and 128 (39%) no longer presented it. The comparison of the pre- and posttherapy results showed: a) a statical significance for the p1, p2, p3, p4, t1, k1, k2 and d6 consonants (McNemar test; p < 0.05); b) a statistical significance for the p consonant in relation to the k, b, d, g consonants and for the t consonant in relation to the b, d, and g consonants (chi-squared test; p < 0.05) in the comparison of the proportion improvement among the 6 occlusive consonants.
Conclusion The ISTP influenced the correction of glottal stops in the speech of individuals with cleft palate.
Mesenteric Panniculitis, Sclerosing Mesenteritis and Mesenteric Lipodystrophy: Descriptive Review of a Rare Condition
Authors: Wagner Christopher , Dachman Abraham , Ehrenpreis Eli D. 
Published: August 2022

AbstractMesenteric panniculitis (MP) is the preferred nomenclature for a continuum of inflammatory diseases of the mesentery. The diagnosis of MP is often based on the appearance of a mass-like structure at the root of the mesentery. Characteristic histology includes focal fat necrosis, chronic inflammation, and sometimes mesenteric fibrosis. At present, robust literature related to diagnosis and management of MP are limited. MP is postulated to be an immune-mediated chronic inflammatory and/or a paraneoplastic disease. A personal or family history of other autoimmune diseases is commonly apparent. Several inciting events have been identified that possibly act as triggers in the development of the disease. Trauma, abdominal surgery, infection, and various cancers have been associated with mesenteric panniculitis.There are several diagnostic and histologic criteria that aid in making the diagnosis of MP. The differential diagnosis for a mesenteric mass includes neoplastic disease, and a biopsy may be indicated to rule out other conditions.While cases of MP with a short duration of symptoms, or spontaneously regression may occur, some patients experience prolonged periods of pain, fever, and alterations in bowel habit, causing significant morbidity. A variety of medical therapies have been suggested for MP. Only two, thalidomide and low-dose naltrexone, have been prospectively evaluated. For patients with chronic MP, good responses to prolonged corticosteroid treatment have been reported. Novel therapies include thalidomide and low-dose naltrexone. Hormonal and immunomodulatory therapies are also used based on small case series, but these treatments may have significant side effects. Surgical intervention is not curative and is avoided except for relief of focal bowel obstruction secondary to fibrotic forms of the disease.
Do communication content functions drive engagement among interest group audiences? An analysis of organizational communication on Twitter
Authors: Agozie Divine Q. , Nat Muesser 
Published: August 2022

AbstractThe value experience perceived by users and the extent of interactivity on social media show how engaging audiences are. Few studies have looked at what drives this value experience in organizational communication. This study explores the functional use of communications by interest group organizations (IGOs) and discerns their effect on user engagement with and without multimedia inclusion on Twitter. A bi-term topic modeling technique is used to analyze posts from 121 organizations, and a generalized linear regression model to assess the link between the content functions and user engagement. The results show that the information and communication content functions include event updates and people recognition. Further, report, event, period, and people communication functions drive a higher engagement with multimedia inclusion, while unite, sign, and glean communication functions are more likely to increase engagement without multimedia elements. This study bridges the gap in the service literature as it pertains to non-profit organizations (i.e., interest group organizations) by exploring organizational communication using communications content functions of Twitter posts. This study is the only one to investigate content functions beyond the categorizations of message functions and the relationship between content functions and user engagement.

The coronavirus disease 19 (COVID-19) pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a coronavirus that spilled over from the bat reservoir. Despite numerous clinical trials and vaccines, the burden remains immense, and the host determinants of SARS-CoV-2 susceptibility and COVID-19 severity remain largely unknown. Signatures of positive selection detected by comparative functional genetic analyses in primate and bat genomes can uncover important and specific adaptations that occurred at virus–host interfaces. We performed high-throughput evolutionary analyses of 334 SARS-CoV-2-interacting proteins to identify SARS-CoV adaptive loci and uncover functional differences between modern humans, primates, and bats. Using DGINN (Detection of Genetic INNovation), we identified 38 bat and 81 primate proteins with marks of positive selection. Seventeen genes, including the ACE2 receptor, present adaptive marks in both mammalian orders, suggesting common virus–host interfaces and past epidemics of coronaviruses shaping their genomes. Yet, 84 genes presented distinct adaptations in bats and primates. Notably, residues involved in ubiquitination and phosphorylation of the inflammatory RIPK1 have rapidly evolved in bats but not primates, suggesting different inflammation regulation versus humans. Furthermore, we discovered residues with typical virus–host arms race marks in primates, such as in the entry factor TMPRSS2 or the autophagy adaptor FYCO1, pointing to host-specific in vivo interfaces that may be drug targets. Finally, we found that FYCO1 sites under adaptation in primates are those associated with severe COVID-19, supporting their importance in pathogenesis and replication. Overall, we identified adaptations involved in SARS-CoV-2 infection in bats and primates, enlightening modern genetic determinants of virus susceptibility and severity.

Abstract
Little information is available about the reproductive and growth performance of local pigs in the tropics. The present paper reviews studies on the Creole pigs of Guadeloupe and Cuba which both originate from an Iberian breed. It was found that Creole sows reached puberty at a younger age than exotic breeds, but Guadeloupe and Cuban Creole sows weaned, respectively, 0.7 and 1.3 piglets per litter fewer than imported females of improved breeds, resulting in fewer pigs weaned/sow/year. Creole pigs had a 14 to 17% lower average daily gain than exotic pigs, and their feed:gain ratio and fat percentage in the carcass were 0.8 and 6-8 percentage units higher, respectively. The higher body fatness in native pigs was accompanied by a 40% lower daily rate of muscle deposition. The effect of breed on postmortem pH, as a criterion of the technological quality of pork, was unclear. When the daily energy intake was sub-optimal, Guadeloupe Creole pigs had a lower average daily gain and a fatter carcass than Large White pigs. In terms of average daily gain and digestibility of fibre, Cuban Creole pigs showed no ability to take advantage of a fibrous diet, but finishing Creole pigs were not adversely affected by a sub-optimal level of dietary crude protein, suggesting that they could be used under conditions of limited protein resources. Guadeloupe Creole pigs benefited from sprinkling and shading to alleviate heat stress under the tropical climate. It is suggested that the indigenous pigs of the Caribbean and Latin America areas would be most useful for the production of high quality transformed products or where conditions of feeding and management were poor.
Dairy value chain operation and dairy producers: its impact and limitations in an emerging economy
Authors: Sarkar Avijit , Gupta Hemant , Dutta Avijan 
Published: August 2022

Abstract
Dairy value chain resilience is significant for food security and socioeconomic sustenance. Core value chain process series: milk production, milk collection, milk processing and sales and distribution duly facilitated by support activities decide the outcome of this value chain. It has become an opportunity to provide self-employment, empowerment of women and economic help to scores of poor milk producers in an emerging economy such as India. On one hand, the dairy value chain can offset the land and seasonal limitation of agriculture and on the other hand, it can shrug off the constraints gradually through economies of scale and enable market access to provide more traction for this dairy sector. Overseeing the value chain with the Three P’s dimensional (people, planet and profit) outlook, milk producer organizations can address the sector pitfalls and concern more comprehensively with the help of systematic production, services, risk assessment and periodical core stakeholders’ review.
No effect of probiotics on leptin levels. An updated mini review
Authors: Papandreou Dimitrios 
Published: August 2022

Abstract
Many human studies have reported controversial results on the benefit of probiotics on leptin levels. White adipose tissue (WAT) secretes leptin and plays an important role in energy balance and glucose homeostasis by decreasing food consumption and acting on fatty acid oxidation and weight reduction. Evidence on probiotics suggests that supplementation may have beneficial effects on lipid metabolism and leptin levels by altering the gut microbiota. However, most of the recent data have shown opposite results.
The upgraded low-background germanium counting facility Gator for high-sensitivity γ-ray spectrometry
Authors: Araujo Gabriela R. , Baudis Laura , Biondi Yanina , Bismark Alexander , Galloway Michelle 
Published: August 2022

Abstract
We describe the upgrade and performance of the high-purity
germanium counting facility Gator, which is dedicated to
low-background γ-ray spectrometry. Gator is operated at the
Gran Sasso Underground Laboratory in Italy, at an average depth of
3600 meter water equivalent, and employed for material screening and
selection in ultra-low background, rare-event search experiments in
astroparticle physics. The detector is equipped with a passive
shield made of layers of copper, lead and polyethylene, and the
sample cavity is purged with gaseous nitrogen maintained at positive
pressure for radon suppression. After upgrading its enclosure, the
background rate is (82.0 ± 0.7) counts/(kg·day) in the
energy region 100 keV to 2700 keV, a 20% reduction compared to
the previously reported rate. We show the stability of various
operation parameters as a function of time. We also summarize the
sample analysis procedure, and demonstrate Gator's sensitivity by
examining one material sample, a candidate photosensor for the
DARWIN experiment.
A new rejuvenation heat treatment of crept Ni-based superalloy single crystals
Authors: Lin Sicong , Shen Hao , Zhou Guangni , He Weifeng , Chen Kai 
Published: August 2022

Abstract
Ni-based superalloys are widely used in harsh environments due to their exceptional high-temperature mechanical properties, and their microstructures are inevitably subjected to degradation, including accumulation of strain/stress, generation of high density of dislocations, and rafting of γ′-particles, under creep damage. To prolong their service life, rejuvenation heat treatment is proposed to restore their microstructure. In this study, a Ni-based superalloy single crystal specimen with 0.15% creep strain is taken as a surrogate of partially served components. The microstructure, including the dislocation density and distribution as well as the size and morphology of γ′-particles, is investigated. Then two comparative heat treatment protocols are applied to the crept superalloy single crystal. Because super-solvus homogenization treatment triggers recrystallization, a recovery pre-annealing step at sub-solvus temperature is designed to relieve the stored deformation energy. After homogenization and aging heat treatment, the single crystalline structure is preserved, and in the meanwhile the γ′-particles are restored to uniform cuboidal morphology and the dislocations are fully eliminated. Our findings provide a route to rejuvenate crept superalloy single crystals.
Network science approach to predict the yield strength of metals containing soft particles and pores
Authors: Andriollo T 
Published: August 2022

Abstract
Local fluctuations in particle size and spatial distributions can substantially affect the yield strength of metals containing soft particles and/or porosities. The phenomenon can be studied via computational homogenization techniques, which, however, can be highly computationally demanding when large representative volume elements are needed. A more efficient approach to model the plastic deformation that controls the yield strength of metals containing pores has recently been proposed by the author and co-workers. The key idea is to treat the material as a network rather than as a continuum. In fact, plastic deformation in porous metals occurs via the formation of shear bands connecting the pores, and it can thus be modelled as a time-evolving network where the nodes represent the pores and the links represent the shear bands. So far, the applicability of this new approach has only been tested against 2D synthetic microstructures. The present work takes it a step further by applying the approach to real spheroidal graphite iron. Based on strain data collected in-situ via digital volume correlation, it is shown that the new network approach can explain the spatial variations of the plastic deformation that arise from local variations of the particle distribution throughout a tensile specimen.
The Neper/FEPX Project: Free / Open-source Polycrystal Generation, Deformation Simulation, and Post-processing
Authors: Quey Romain , Kasemer Matthew 
Published: August 2022

Abstract
In the past couple of years, efforts have lead toward the convergence of two established software packages: Neper, developed primarily at CNRS and Mines Saint-Étienne, and FEPX, developed historically at the Deformation Process laboratory at Cornell University and (since 2020) at the Advanced Computational Materials Engineering Laboratory at the University of Alabama. The objective was to create an extensive and homogeneous ensemble for polycrystal plasticity studies that includes polycrystal generation and meshing, parallel finite-element crystal-plasticity simulation, post-processing and visualization. The two programs were upgraded to common standards, both in terms of usage and resources. Collectively, the project is under active development and distributed under free / open-source license (see both: https://neper.info, https://fepx.info).
Microstructural evolutions induced by an electrical breakdown in a binary Cu-25Cr alloy

Published: August 2022

Abstract
Cu-Cr based alloys with a high Cr content are widely used as electrical contact materials in vacuum interrupters due to their good combination of electrical, thermal, and mechanical properties. During a current interruption process in a vacuum, the establishment of an electrical arc results in a severe local thermal input onto the contact material surface. Few studies have closely investigated the microstructural evolution during this phenomenon as well as the Cu-Cr alloy properties evolution. This study reports the microstructural, electrical conductivity, and hardness evolution of a Cu-25Cr (25 wt%Cr) solid state sintered alloy as electrical contact before and after successive current interruptions. Electron scanning and optical microscopy show that this microstructural evolution is a result of a complex phenomenon. Local and heterogeneous thermal conditions take place resulting in significant microstructural evolution. The resulting microstructure is related to out-of-equilibrium solidification conditions. Electrical conductivity is decreased by half in the whole thermally affected zone by the electrical arc and hardness is multiplied by three to four times.
The heterogeneous microstructure in an Al-Zn-Mg-Cu-Sc-Zr alloy produced by selective laser melting
Authors: Zhu Y Y , Pan W , Li Y Y , Huang T L , Zhang Y Z , Huang X 
Published: August 2022

Abstract
Fully dense and crack-free Al-Zn-Mg alloys with Sc and Zr additions were successfully fabricated by selective laser melting. The microstructures of as-built alloys with different Sc and Zr additions were characterized by scanning electron microscopy and transmission electron microscopy. The microstructure was composed of coarse columnar grains without Sc and Zr additions. In contrast, a fine heterogeneous microstructure, consisting of equiaxed grains at the bottom of the melt pool and columnar grains in the remaining volumes, was formed by adding 0.6 wt.% Sc and 0.26 wt.% Zr. In addition, a high density of precipitates was identified as η’ and I-phases that were distributed at grain boundaries and inside grains.
Revisiting plastic strain ratio determination in aluminium using crystal plasticity
Authors: Lindell D 
Published: August 2022

Abstract
Determination of plastic strain ratio (r, also known as the Lankford coefficient) from texture data is one of the most widely used applications of crystal plasticity methods. Early attempts using Taylor theory and x-ray texture data already provided practically useful information of e.g. drawability of sheet metals. Developments in recent decades within both electron backscatter diffraction and computational mechanics have significantly improved the accuracy of these calculations. Predictions can now be made that compares relatively well with experiments making r-value predictions from texture data a routine method within material and process development. The current work reviews recent studies on plastic strain ratio determination by computational means for aluminium sheet metal, with the aim to assess the expected accuracy using modern crystal plasticity methods. Furthermore, we investigate the major sources of error in these calculations by comparison between previous studies and with new experiments and calculations. In particular, we observe and investigate a maximum in the absolute error occurring typically at 45° to the rolling direction. The sources of this error are discussed in terms of both model conditions and the material heterogeneities giving rise to anisotropy.

Published: August 2022

Abstract
This study revealed characteristics of the deformation behavior in high/medium entropy alloys (HEAs/MEAs) with face-centered cubic (FCC) structure. A Co60Ni40 alloy and a Co20Cr40Ni40 MEA having low and high friction stresses (fundamental resistance to dislocation glide in solid solutions), respectively, but similar in other properties, including their stacking fault energy and grain sizes, were compared. The MEA exhibited a higher yield strength and work-hardening ability than those in the Co60Ni40 alloy at room temperature. Deformation microstructures of the Co60Ni40 alloy were composed of coarse dislocation cells (DCs) in most grains, and a few deformation twins (DTs) formed in grains with tensile axis (TA) nearly parallel to <111>. In the MEA, three microstructure types were found depending on the grain orientations: (1) fine DCs developed in TA~//<100>-oriented grains; (2) planar dislocation structures (PDSs) formed in grains with other orientations; and (3) dense DTs adding to the PDSs developed in TA~//<111>-oriented grains. The results imply difficulty in cross-slip of screw dislocations and dynamic recovery in the MEA, leading to an increase in the dislocation density and work-hardening rate. Our results suggest that FCC high-alloy systems with high friction stress inherently develop characteristic deformation microstructures advantageous for achieving high strength and large ductility.
Finite element modelling of indentation testing in an AA1050 microstructure
Authors: Goutianos S , Pan H , Zhang X 
Published: August 2022

Abstract
Heterogeneous microstructures can be produced in structural metals from heterogeneous deformation, and they can also be purposely designed to meet specific requirements in high-demanding engineering applications. When designing a heterogeneous microstructure in metallic materials, it is important to know the local mechanical properties such as the stress-strain behavior. However, due to the local varying microstructure, direct measurement of the local mechanical properties is not feasible either by bulk testing or by miniature testing. In this work, an iterative approach, based on the finite element method and under the assumption that the local mictrostructure is homogeneous, will be presented as an example to extract the local mechanical properties of cold-rolled AA1050 from indentation tests as an example. The uncertainties of the proposed method are discussed.
