Energy Absorption Performance of Bio-inspired Honeycombs: Numerical and Theoretical Analysis
Authors: Sherman John , Zhang Wen , Xu Jun 
Published: September 2021

AbstractEnergy absorption performance has been a long-pursued research topic in designing desired materials and structures subject to external dynamic loading. Inspired by natural bio-structures, herein, we develop both numerical and theoretical models to analyze the energy absorption behaviors of Weaire, Floret, and Kagome-shaped thin-walled structures. We demonstrate that these bio-inspired structures possess superior energy absorption capabilities compared to the traditional thin-walled structures, with the specific energy absorption about 44% higher than the traditional honeycomb. The developed mechanical model captures the fundamental characteristics of the bio-inspired honeycomb, and the mean crushing force in all three structures is accurately predicted. Results indicate that although the basic energy absorption and deformation mode remain the same, varied geometry design and the corresponding material distribution can further boost the energy absorption of the structure, providing a much broader design space for the next-generation impact energy absorption structures and systems.

Published: September 2021

AbstractFood system analysis in arid and semi-arid countries inevitably meets water availability as a major constraining food system driver. Many such countries are net food importers using food subsidy systems, as water resources do not allow national food self-sufficiency. As this leaves countries in a position of dependency on international markets, prices and export bans, it is imperative that every domestic drop of water is used efficiently. In addition, policies can be geared towards ‘water footprints’, where water use efficiency is not just evaluated at the field level but also at the level of trade and import/export. In this paper, Egyptian food systems are described based on production, distribution and consumption statistics, key drivers and food system outcomes, i.e., health, sustainable land and water use, and inclusiveness. This is done for three coarsely defined Egyptian food systems: traditional, transitional and modern. A water footprint analysis then shows that for four MENA countries, differences occur between national green and blue water volumes, and the volumes imported through imported foods. Egypt has by far the largest blue water volume, but on a per capita basis, other countries are even more water limited. Then for Egypt, the approach is applied to the wheat and poultry sectors. They show opportunities but also limitations when it comes to projected increased water and food needs in the future. An intervention strategy is proposed that looks into strategies to get more out of the food system components production, distribution and consumption. On top of that food subsidy policies as well as smart water footprint application may lead to a set of combined policies that may lead to synergies between the three food system outcomes, paving the way to desirable food system transformation pathways.

Published: September 2021

AbstractPredicting formation damage in cased-hole and open-hole completion wells is of high importance. This is especially relevant when the damage is caused by reservoir drill-in fluids hence being well-bore induced. Cake filter removal has proven to be a good approach to estimate induced damage and to evaluate drill-in fluids’ performance. We present an experimental methodology to evaluate filter cake removal, which could be achieved during the well's initial production. An improved experimental setup, to the ones presented in literature, has been developed to enhance data quality. A twofold approach was used for setup design, and first, it can be integrated with devices used to evaluate the static/dynamic filter-cake. Second, it can be used to simulate more realistic cases (field related) by adjusting the experiment parameters. Hence, to replicate the expected drawdown pressure as well as the corresponding flow rate of the studied reservoir. Three key indicators directly related to filter-cake removal were used as evaluators in this work. Lift-off pressure, internal and external filter cakes removal efficiency. Three reservoir fluid systems were studied, two polymer-based and one potassium carbonate. Results show that pressure required to initiate the collapsing process of the filter cake is not significant. Polymer-based drilling fluids showed better performance in terms of external and internal filter cake cleaning efficiency comparing to potassium carbonate. Moreover, we observed that filtrate volume has no clear relation with the degree of residual damage.
Ecological, Commercial and Economic Significance of the Tree Lucerne: A Review
Authors: Habtemariam Akale Assamere 
Published: September 2021

AbstractCurrently, the Lucerne tree is becoming well-established and adapted in many parts of the world. It can be grow in and around apple trees, near Rahminus prinoides, and within the vegetables. According to African Rising Stations project on Tree Lucerne, line planting, cutting, periodic pruning, and reduce the height by 1.5 m is that the simplest caring mechanism. It has also been shown that this care can result in a 20% increase in DM production on grazing alone. It store about 6 tonnes CO2 equivalent per hectare per year and highest N-fixer among legume, it fixes about 590 kg of N2 per year per hectare. It is mainly used for animal husbandry, treat degraded ecosystems and to have good nutrients. Beyond the nutrients, it is an alternative food guarantee as it can withstand drought and stay green during the summer, especially when there is a shortage of food. Lucerne tree is used as a raw material for pulp and paper work as a group of eucalyptus, holocellulose, lingin, xylan and acetyl groups. However, in addition to fodder, there are significant limitations on energy, paper, tissue and chemical use. The leftovers should be converted into useful products. Therefore, these plants should be used for good quality of wood trim for grain and paperwork.

After global governance
Authors: Neyer Jürgen 
Published: September 2021

AbstractTechnology is of crucial importance for understanding the recent crisis of global governance and concomitant practices of re-territorializing sovereignty. It is far more than an instrument for putting ideas and interests into practice; it is embedded in relationships of power, gives expression to normative decisions and shapes the conditions under which politics is conducted. Technology empowers some actors and disempowers others. It makes new forms of political action possible and others more costly. This crucial role of technology has been emphasized in many dispersed parts of the IR discourse since long. What has often been overlooked, however, is that technological innovation can have a disruptive effect on international institutions. This paper traces this disruptive effect in the administration of the internet by underlining the close nexus between technology, sovereignty and global governance. It finally discusses promising avenues for future research.

Published: September 2021

AbstractIntroductionRomantic experiences during adolescence have an important influence on functioning later in life. Romantic love has been associated with the acceptance of abusive behaviors. This study examined the relationship between myths of romantic love and the perceived severity of different types of abusive behaviors, as well as the influence of gender.MethodsThe sample comprised 448 Spanish adolescents (M = 12.92 years old; SD = 0.85), of which 50.3% were male and 49.7% were female. Participants were evaluated in the school setting. The Perception of Abuse Scale and the Myths, Fallacies, and Misconceptions about Romantic Love Scale were administered.ResultsStatistically significant negative associations between the myths of romantic love and the perceived severity of abusive behaviors were found. Myths regarding possession, dedication, and exclusivity were associated with a lower perceived severity of abusive behaviors in adolescent males. Myths regarding the omnipotence of love were associated with a lower perceived severity of abusive behaviors in adolescent females. Believing in jealousy as a demonstration of love (myth of jealousy) and in the need to establish a steady union when you love someone (marriage myth) explained a lower perceived severity of abusive behaviors in regression models. However, being female and having these beliefs explained a higher perceived severity of abusive behaviors.ConclusionsThe myths of romantic love are already present during early adolescence. These beliefs are implicated in the construction of gender inequality and difficulties in the identification of dating abuse behavior severity. A gendered perspective is necessary to understand this issue. Early intervention strategies should address the cognitive and emotional components of intimate relationships.
The Shifting Pendulum: Foreign Investors’ Liability Under Canada’s Common Law for Breaches of Customary International Law
Authors: Haynes Jason 
Published: September 2021

AbstractIn February 2020, the Supreme Court of Canada rendered a decision—Nevsun Resources Ltd. v. Araya, 2020 SCC 5—that can properly be described as revolutionary. In Nevsun, the court found that a Canadian corporation operating in a host state, Eretria, could be liable under Canadian domestic law for human rights abuses committed in Eritrea under customary international law, as incorporated into Canadian domestic law. The decision merits special attention because it is likely to fundamentally change the relationship between foreign investors, host states and the residents of host states adversely affected by investors’ unlawful conduct which amount to modern slavery.

GENERALIZED GREEN FUNCTIONS AND UNIPOTENT CLASSES FOR FINITE REDUCTIVE GROUPS, III
Authors: SHOJI TOSHIAKI 
Published: September 2021

AbstractLusztig’s algorithm of computing generalized Green functions of reductive groups involves an ambiguity on certain scalars. In this paper, for reductive groups of classical type with arbitrary characteristic, we determine those scalars explicitly, and eliminate the ambiguity. Our results imply that all the generalized Green functions of classical type are computable.

AbstractObjectiveThe aim of the present study was to perform a retrospective review of the lesion sites in congenital middle-ear cholesteatoma and any accompanying ossicular defects, as well as to explore the possible aetiology of congenital middle-ear cholesteatoma associated with such ossicular chain defects.MethodThe clinical characteristics and pathogenic mechanisms of ossicular chain defects were investigated in 10 patients with early-stage congenital middle-ear cholesteatoma confirmed by surgery, from August 2011 to February 2019.ResultsMonofocal cholesteatoma was located in the anterosuperior quadrant in 3 cases and in the posterosuperior quadrant in 7 cases; all 10 cases showed an absence of the long crus of incus, and 8 cases showed a complete or partial absence of stapes superstructure. The lesions were confined to the vestibular window and the stapes region and had no contact with the long crus of the incus or stapes in nine cases. None of the 10 patients had any recurrence of cholesteatoma.ConclusionAlthough cholesteatoma can cause erosion of ossicles, the present cases suggest that residual epithelium of the cholesteatoma may coexist with ossicular malformations. Therefore, the aetiology of the clinical characteristics in these patients may derive from residual epithelial hinderance of ossicle development.
The development of narrative skills in monolingual Swedish-speaking children aged 4 to 9: a longitudinal study
Authors: LINDGREN Josefin 
Published: September 2021

AbstractThis longitudinal study investigated the development of oral narrative skills in monolingual Swedish-speaking children (N = 17). The MAIN Cat/Dog stories were administered at four timepoints between age 4 and 9. Different narrative aspects were found to develop differently. In story comprehension, the children performed high already at T1 (4;4) and were at ceiling at T2 (5;10), whereas story structure developed significantly until T4 (9;4). Narrative length and syntactic complexity reached a plateau at T3 (7;4). Referent introduction was not mastered until T4. The results suggest that general conclusions regarding the development of narrative skills depend on the specific aspects studied.

AbstractMucosal immunity of Indian Antarctic personnel was analysed during the 34th Indian Scientific Expedition to Antarctica (ISEA) by ship voyage. Serum and salivary IgA, IgA1 and IgA2 levels along with salivary cortisol and TGF-β were quantified by enzyme-linked immunosorbent assay. Samples were collected at three different time points (T1, T2 and T3) during the expedition. Serum and salivary IgA, IgA1 and IgA2 concentrations incrementally increased towards the end of the expedition as compared to the beginning of the expedition. Salivary IgA and TGF-β levels were significantly altered during the expedition. Levels of IgA1 (P = 0.0007) and IgA2 (P = 0.0135) increased significantly at T3 as compared to T1. Additionally, significant changes in serum IgA were observed, with peak levels at T3 (P = 0.0015) and T2 (P < 0.001). However, the level of serum IgA2 was also significantly altered at T3 (P < 0.05) and T2 (P = 0.0006) in comparison with T1. The exact cause of the changes in serum and salivary IgA, IgA1, IgA2 and TGF-β levels during the summer expedition are unknown; however, the changes are evident in mucosal immunity.

Published: September 2021

AbstractBackground:Coronary artery aneurysms are well-described in Kawasaki disease and the Multisystem Inflammatory Syndrome in Children and are graded using Z scores. Three Z score systems (Boston, Montreal, and DC) are widely used in North America. The recent Pediatric Heart Network Z score system is derived from the largest diverse sample to-date. The impact of Z score system on the rate of coronary dilation and management was assessed in a large real-world dataset.Methods:Using a combined dataset of patients with acute Kawasaki disease from the Children’s Hospital at Montefiore and the National Heart, Lung, and Blood Institute Kawasaki Disease Study, coronary Z scores and the rate of coronary lesions (Z ≥ 2.0) and aneurysms (Z ≥ 2.5) were determined using four Z score systems. Agreement among Z scores and the effect on Kawasaki management were assessed.Results:Of 333 patients analysed, 136 were from Montefiore and 197 from the Kawasaki Disease Study. Age, sex, body surface area, and rate of coronary lesions did not differ between the samples. Among the four Z score systems, the rate of acute coronary lesions varied from 24 to 55%. The mean left anterior descending Z scores from Pediatric Heart Network and Boston had a large uniform discrepancy of 1.3. Differences in Z scores among the four systems may change anticoagulation management in up to 22% of a Kawasaki population.Conclusions:Choice of Z score system alone may impact Kawasaki disease diagnosis and management. Further research is necessary to determine the ideal coronary Z score system.
Prominent prolapsing Chiari network: presentation and prognosis in paediatric patients
Authors: Joyce James J. , Joyce Thomas R. , Ferns Sunita J. 
Published: September 2021

AbstractChiari network is an infrequently visualized web-like structure in the right atrium that is usually thin and small. Rarely, it can be prominent and elongated with protrusion into the right ventricle during diastole and complications have been reported. Thirty-eight patients (median age 2.5 years) with prolapsing Chiari network were identified and associated cardiac abnormalities documented. Echocardiographic right and left heart parameters were measured and compared to normative data. At presentation, the extent of Chiari network prolapse below the tricuspid annulus was 9.1 ± 3.5 mm (mean ± standard deviation), mean pulmonary valve annulus diameter z-value was reduced (-0.91 ± 0.64), and mean aortic valve z-value was enlarged (+0.97 ± 0.87). Fourteen patients exhibited no other cardiac abnormality. Eight were noted to have atrial septal defects, eight demonstrated supraventricular dysrhythmias, six had mild to moderate tricuspid valve regurgitation, and one patient each had an atrial septal aneurysm, severe pulmonic valve stenosis, small perimembranous ventricular septal defect, bicuspid aortic valve, and mild right upper pulmonary vein stenosis. Fourteen patients (37%) were seen in follow-up from 1 to 8.5 years later (median 3.2 years). During that time, the magnitude of prolapse across the tricuspid valve decreased by up to 7 mm (median 2 mm). Interventions were required in three patients, but many associated cardiac abnormalities resolved spontaneously with growth. Thus, the presence of a prolapsing Chiari network has a substantial risk of associated CHDs. However, the extent of Chiari network prolapse gradually decreases and many related abnormalities resolve during growth.

Published: September 2021

AbstractObjective:This study aimed to characterise the availability, the nutritional composition and the processing degree of industrial foods for 0–36-month-old children according to the neighbourhoods affluence.Design:A cross-sectional exploratory study.Setting:All food products available in retail stores for children aged 0–36 months were analysed. Data collection took place in two neighbourhoods, comparing two different sociodemographic districts (highv.low per capita income), Campanhã and Foz do Douro in Porto, Portugal.Participants:A total of 431 commercially processed food products for children aged 0–36 months which are sold in 23 retail stores were identified. Food products were classified according to their processing degree using the NOVA Food Classification System.Results:For NOVA analysis, of the 244 food products that were included 82 (33·6 %) were minimally processed, 25 (10·2 %) processed and 137 (56·1 %) ultra processed. No food product was classified as a culinary ingredient. The products included mostly cereals, yogurts, prevailed in high-income neighbourhoods for the 0–6-month-old group. It was observed that some categories of ultra-processed food (UPF) presented higher amounts of energy, sugars, saturated fat and salt than unprocessed/minimally processed products.Conclusions:The high availability of UPF offered for 0–36-month-old children should be considered when designing interventions to promote a healthy diet in infancy.
“The Hall Does Not Make the Space”: Disrupting Concert Hall Norms in Hannibal's One Land, One River, One People
Authors: Safran Benjamin 
Published: September 2021

AbstractHannibal's cheering and shouting along with his request for audience participation during the 2015 premiere of his composition One Land, One River, One People caused a stir and created discomfort among the Philadelphia Orchestra audience. I interpret his work as an example of a successful musical direct action within contemporary orchestral music. By exposing and subverting the traditions of the classical concert experience, One Land, One River, One People highlights social boundaries within the genre of classical music itself. I apply Robin James's (2015) concept of Multiracial White Supremacy, or MRWaSP, to contemporary orchestral classical music of the United States. Under late capitalism, MRWaSP helps to explain the potential appeal to an orchestra of commissioning Hannibal, who is known as a “genre-crossing” composer rooted in classical and jazz. Yet I argue that the way in which Hannibal performs his identity along with the piece's inclusion of audience participation allow the music to resist functioning as expected under MRWaSP. Rather than promoting a sense that—as one might expect from the title—we are all “one people,” I see the piece as revealing racial difference and as speaking truth to power.
