Exodus
Authors: Jackson Alicia K.
Published: May 2022

Anderson’s election to the Georgia Senate, along with other members of the Republican delegation from the 23rd district, is met with widespread condemnation and threats of violence. As Black political representation dwindles following the 1870 election, the remaining Black legislators in the state attempt to institute policies to protect Black Georgians, but with little success. Blacks continue their exodus from Georgia due to oppressive conditions, and Isaac Anderson becomes a target for arrest.
Early Days
Authors: McFarlane Brian
Published: May 2022

This chapter deals with Fred Schepisi’s family background and education, as well as his entry into filming. Schepisi’s earliest career was with an advertising firm for whom he made commercials. Becoming production manager for Cinesound Production and then setting up his own company, The Film House, he obtained experience with the business aspects of film production, which would stand him in good stead when he became a feature-film director.
Emerging Filmmaker
Authors: McFarlane Brian
Published: May 2022

The 1970s was a key decade in Australian filmmaking and Schepisi became one of the key directors. He contributed a segment to the portmanteau film, Libido, before his first features as director. Libido drew on Schepisi’s Catholic upbringing and brought him in contact with several collaborators with whom he would subsequently work again. His first feature, The Devil’s Playground, offered a critical but even-handed account of the seminary education he renounced.
Schepisi and the Chamberlain Affair— A Cry in the Dark
Authors: McFarlane Brian
Published: May 2022

Probably no Australian court-case has ever caused a more frenzied media reaction than this in which a mother was accused of killing her own child. Set in remote desert location, the film deals with the torment imposed on the Chamberlain family, the mother’s jail sentence, and final proof of innocence. The real villain of the film is the outrageous behaviour of the media. The film posed many production problems, but the outcome is utterly gripping, emotionally and visually.
White Comedians, Strategic Racist Humor, and the (Re)Normalization of Racism
Authors: Pérez Raúl
Published: May 2022

This essay by Raúl Pérez is a critical examination of comedian Lisa Lampanelli and the development of what Pérez calls neoliberal white racial comedy—a commercial racial comedy where the history, significance and persistence of racism and racial inequality is minimized, trivialized and monetized. This brand of comedy took root in the post-civil rights period and is upheld and reinforced through a deliberate set of comic performance practices that work to veil the use of comic racist talk as “not racist” and commercially palatable. This denial and trivialization of racism has worked to grant white comics and humorists discursive license to use and profit from racist jokes, narratives, and slurs unapologetically under the guise of humor, comic free speech, and as an attack on so-called “political correctness.” Pérez contends that this strategic deployment of racist humor by white comedians like Lampanelli contributed to the normalization of racist discourse in an ostensibly colorblind society, where racist talk was disavowed more broadly.
Jerry Seinfeld Versus PC Social Media
Authors: Viator Timothy J.
Published: May 2022

This essay by Timothy J. Viator attempts to show how Jerry Seinfeld exemplifies the stand-up comics of his era and their reactions to audiences’ criticism published on social media, and to understand Seinfeld’s defense of comedy by considering “professional dissonance.” Adopting the role of the “gatekeeper” public intellectual, Seinfeld politicizes negative reviews of a comedian’s work as an example of what is called “PC Culture.” Professional dissonance arises when professionals with an idealized view of their work feel discomfort as they confront the reality of their work and must address a “task” that conflicts with that idealized view. Now that social media allows audience new ways to criticize their work, established comedians now must rethink and revise jokes and bits to correspond to emerging sensibilities and new views of comedy.
The Comedian as Preacher
Authors: King Rob
Published: May 2022

This chapter by Rob King examines the rhetorical strategies of Texas-based stand-up comedian Bill Hicks (1961-1994) as a framework for rethinking comedy’s powers of dissent in non-secular terms. By and large, most scholarship on comedy as a tool of social critique has operated within the secular/rationalist orbit of public sphere theory. Hicks, by contrast, drew upon his religious upbringing to model a style of critical dissent grounded in the idea of mystic commitment. The chapter follows the implications of this across two axes: first, by examining Hicks’s comedy in relation to key tropes of Fundamentalist rhetoric; then, by relating Hicks’s critique to what philosophers have described as an “ethics of the Real.” If, as Ernesto Laclau argues, the importance of mysticism is that it registers a “beyond” of human finitude, then Hicks uniquely claimed that “beyond” as a vantage point for comedic critique.
World’s Fairs, Symphony Halls, and America’s Racial Others
Authors: Talusan Mary
Published: May 2022

This chapter interrogates the ways that music was embroiled in debates about race, civilization, and American identity during the early 20th century. Military band music with its pleasing repertoire of European “high-class” music and American patriot marches brought a certain audible order to the racial cacophony of the early 20th century brought about by U.S. expansion to overseas territories, waves of immigration, and African American migration out of the south. The popularity of the Philippine Constabulary Band served to emphasize American benevolence during the contentious colonization of the Philippines by downplaying Filipinos’ long history of cultural influence by Europe. A bizarre characterization that Filipinos were child-like but musically talented savages before American rule attempted to negate accusations by anti-imperialists that the U.S. was colonizing a people who were already capable of self-rule. Heard with an imperial ear, Talusan argues, American audiences’ enjoyment of the PC Band’s music-making was an exercise of imperial and racial power.

Prelude

Published: May 2022

Jazz in socialist Vietnam is no dissident sound played in the shadows, not since Minh publicly performed the genre in two officially endorsed solo recitals in 1988 and 1989. With the end of the First Indochina War, all forms of cultural arts and performances considered as unfaithful to the ideology of the revolution were restricted and even banned in the communist ruled North. Any trace of jazz introduced during the French colonial era disappeared entirely. The Đổi Mới reforms led to steady decollectivization of Vietnamese society, introduction of a market economy in the socialist state, and subtle loosening of political control over every aspect of life. The party and the state retained ultimate authority of what could be played, heard, and learned. It was in this context that Quyền Văn Minh endeavored to play jazz in Vietnam.
Interlude I
Authors: Tan-Tangbau Stan BH , Minh Quyền Văn
Published: May 2022

Minh’s early encounters with jazz in socialist Vietnam invites a broader contextualization of jazz during the Cold War, in particular, the stories of jazz “behind the Iron Curtain.” Adopted as a cultural instrument in the ideological competition by both sides in the Cold War, jazz was ironically able to persist and even developed its own individual characteristics in different countries behind the Iron Curtain. Indeed, there was jazz in the socialist states after the Stalinist era. But in socialist Eastern Europe and the Soviet Union, where classical music was deep rooted and flourished, and folk music deemed as a rich source of national pride in the respective countries, jazz was always placed a tier or two below the mainstream arts. Nonetheless, jazz continued to persist behind the Iron Curtain.
Minh’s Jazz Club Reprise
Authors: Tan-Tangbau Stan BH , Minh Quyền Văn
Published: May 2022

For over twenty years, Minh’s Jazz Club has been the venue where Vietnamese musicians in Hà Nội have their first experience of playing jazz for a live audience, where they first listened to live jazz, or wanted to be on stage to indulge in a night of just playing pure jazz. In 1997, Minh’s Jazz Club opened its doors at Giảng Võ Exhibition Centre but had to close after three months when the venue was slated for redevelopment by the government. The club moved into the heart of Hà Nội city centre at 16 Lê Thái Tổ in 1998 but again, it had to close after less than a year when the building was designated for other purposes. Minh’s Jazz Club finally found a long-term home at 31 Lương Văn Can, a premise coincidently owned by Thăng Long Song and Dance Troupe, Minh’s former employer. In 2014, Minh’s Jazz Club finally moved into the cultural arts hub in the city centre at 1 Tràng Tiền, behind the majestic Hà Nội Opera House.
Postlude
Authors: Tan-Tangbau Stan BH , Minh Quyền Văn
Published: May 2022

Chapter 13 temporarily sums up the state of jazz in Vietnam in parallel with Minh’s life. For Minh, promoting jazz in socialist Vietnam has always been about bringing this highly innovative art form to different quarters of Vietnamese society, and most importantly, developing an original voice to play on “planet jazz” (to borrow Atkins’ term). Minh’s modus operandi has always been a blending of familiar Vietnamese musical sounds, the timbre of the saxophone, and his subtle, melodic improvisations on stage to coax the uninitiated Vietnamese listener to be a little more receptive to the sound of jazz. He would play for anyone in any setting and anywhere.

Mental illness is a psychological impairment involving emotions, cognitions, and behaviors, and its prevalence is increasing worldwide. Dental students may encounter patients with underlying psychological problems during their training. Objective: To evaluate dental students’ perception, attitude, and willingness to interact with patients with mental illness. Methods: A multi-center cross-sectional study was conducted involving undergraduates at three dental institutions in Malaysia using an online self-administered questionnaire. Descriptive data analysis was conducted and statistical analysis using chi-square test was done for associations (p < 0.05). Results: The response rate was 63% (225); the majority of respondents were female (77.8%) and of Malay ethnicity (88.4%). Our study found that positive attitudes are independent of respondents’ sociodemographic profiles. No significant differences in attitudes were portrayed by gender, race, or history of mental illness. Our findings suggest that respondents’ place of study, gender, and previous encounter with mental illness are associated with willingness to interact with patients (p < 0.05). Conclusions: Dental students displayed positive attitudes and willingness to interact with patients with mental illness. However, to further improve students’ attitudes and enhance their readiness to interact with patients with mental illness, more mental health-related educational programs should be introduced in the dental curricula.
Orthogonal Constrained Meta Heuristic Adaptive Multi-View Clustering over Multi Labeled Categorical Data Analysis
Authors: Kolli Srinivas , Sreedevi M.
Published: May 2022

In data mining, clustering is the one of the efficient research concept in real time data analysis, evaluation of attribute representation in clustering is main issue in artificial intelligence related research areas. Multi labeled clustering gives high amount of valuable data, which describes the evaluation and representation of attribute be the trending concept in multi labeled categorical data analysis. Multi dimensional clustering is combined complementary data from different dimensions to provide efficient clustering results in various conditions. Different multi view clustering techniques are proposed traditionally but they can give output as single clustering with input data. Because of multiplicity, multi dimensional data can have different grouping data which are reasonable consist perspective attributes. So how to find measurable and reasonable cluster results which are represented in multi view labeled data is still challenging task, so that in this paper, we propose a novel approach i.e. Orthogonal Constrained Meta Heuristic Adaptive Multi-View Clustering (OCMHAMVC) to represent data as a cluster with different categories. Based on multi labeled data, first proposed approach evaluates low dimensional data using optimized matrix factorization (OMF) method and clusters the similar labeled sample data into prototype cluster of dimensional data. After that we represent data in desirable orthonormality constrained view of data using adaptive heuristic to combine complementary data from different dimensions, also provide complexity in computational analysis of data representation. Experimental results of proposed approach applied on high amount of multi view data gives scalable and efficient performance with comparison to traditional multi view related clustering approaches.
Evaluating the occurrence of increased postoperative cardiac enzymes in patients with coronary atherosclerotic obstruction
Authors: Zhang Wanyi , Jin Feng , Zhou Heng , Wang Wenzhi
Published: May 2022

Percutaneous transluminal coronary angioplasty (PTCA) has been accepted as the elective treatment in many patients with coronary atherosclerotic obstruction. A slight increase in cardiac markers after the percutaneous coronary intervention (PCI) has been commonly reported. Some researchers have suggested that it predicts mortality and long-term complications. This study aimed to evaluate the occurrence of increased postoperative cardiac enzymes and determine the relationship between such an increase and clinical angiographic and technical variables. For this purpose, the descriptive study was performed in Hospital's cardiac ward from 2020-to 2021. One hundred twenty-two patients with stable coronary artery disease were studied for elective PTCA implanted with successful and uncomplicated stenting. Blood samples were taken from all patients to measure cardiac markers 20 hours after surgery. The normal range was CTnI ≤ 2ng/ml and CKMB ≤ 24 IU/L. Plasma levels of myocardial infarction and their relationship with clinical variables (including age, sex, risk factors for coronary artery disease, the severity of symptoms based on ccs class and previous history of acute coronary syndromes), angiographic including (lesion type, severity of stenosis) or related to the operation (operation on one or two vessels and direct stenting versus PTCA + stenting) were recorded in a questionnaire and observation sheets. The collected data were processed using descriptive statistics, frequency distribution tables, Chi-square, and student t-tests. Abnormal values of myocardial infarction were observed in 46.72% (57 patients). An increase in CTnI was observed in 39 patients (31.96%) and an increase in CKMB was seen in 31 patients (25.40%). Although the rise in CTnI exceeded the CKMB, the difference between the two was not statistically significant. The increased CTnI was significantly higher in older people, and the increase in CKMB was significantly higher in hypertensive individuals (p = 0.01). Based on the findings of this study, there is an increase in enzymes after successful and uncomplicated PCI selection. Increased CTnI occurs more frequently than CKMB. There is no relationship between enzyme enhancement and other clinical, angiographic, and technical variables.
Realizing Gramsci’s Dream: A Case Study of Vernacular Sundanese Linguistic Contra-Hegemony
Authors: Wattimena Sari
Published: May 2022

The need to promote egalitarianism and reduce the colonial influence in language drives civil society actors and organizations operating within the community to revive their vernacular language, replacing hierarchical standard language exist in their community for a long time. Gramsci’s and Lu Xun’s efforts to promote vernacular language in Italy and China at their times faced failure. Today, in the democratic and digital-dominated society of Indonesia, the same effort has been taken by Aing Tangerang Foundation. This civil organization tries to revive egalitarian Sundanese language against hierarchical Sundanese brought by colonialism. One of their efforts is to popularize the word “Aing”, which means “I” in Sundanese conversation. The word is considered harsh by the majority of Sundanese using hierarchical standards. However, in Tangerang Regency, it is part of their mother tongue. This paper reports on a case study of the vernacular Sundanese linguistic revival campaign taken by the Aing Tangerang Foundation and strategies, drivers, and barriers they faced while promoting their cause. The data is collected through in-depth interviews with three informants: one expert in Sundanese literature, one expert in Sundanese history, and one is the leader of said organization. The research method is qualitative-phenomenological hermeneutics. We use Gramsci's hegemonic theory to analyze and discuss the findings. The results are presented and discussed related to horizontal and vertical strategies; political, organizational, and technological drivers; and historical, psychological, sociological, and sociofacts barriers.

The work presents the occurrence of snow cover in the western part of the Western Beskids in the years 1991–2020. We have analysed data from climate research stations of the IMGW-PIB located in Brenna, Laliki, Zawoja, Radziechowy (1991–2007)/Nowy Dwór (2008–2020). We calculated the number of days with snow cover for each winter seasons, the number of days with permanent snow cover, the potential duration of snow cover and the sum of seasonal snow cover thicknesses. The snowiness classes of Chrzanowski winters and the snowiness index of Paczos were determined from the sums of the thickness of the snow cover. The snowiest season was the 2005/06 winter season, while the thinnest snow cover was observed in the 2013/14 season. There are clear relationships between the height above sea level and the time of snow cover occurrence, as well as its thickness.
TEMPERATURE DIVERSIFICATION OF THE SURFACE LAYER OF WATER IN THE KARST LAKES IN THE STASZÓW REGION (NIDZIAŃSKA BASIN)
Authors: ZIELIŃSKI ARTUR
Published: May 2022

The north-eastern part of Nidziańska Basin, near Staszów, boasts a large grouping of small but relatively deep lakes of karst origin. In 2010, 26 of them underwent regular measurements of the temperature of their surface layer of water. The results show that although the basins are situated close to each other and the area has similar characteristics, the temperature differs significantly. The thermal differences reach 11.6ºC. The warmest lakes appear to be Lake Łajba, Duży Staw, Lakes Torfowe I and Torfowe II. However, the coldest surface water is in lakes Piąty Staw, a small unnamed lake located near Lake Ciemne and an unnamed lake sandwiched between Lake Szyja and Lake Jasne.The fact that the temperature of the water goes up results directly from solar radiation, which was the strongest in the case of Lake Łajba, located in an open area. However, the coldest basins were located in the central parts of the lakes of the floating peat islands. Those biogenic islands are perfect “insulators”, protecting the water from thermal radiation. Moreover, the lakes which are fed with soligenous water supplies, tend to have a lower temperature.

The research covered three genetic groups of lakes (karst, aeolian, and riverine) which occur in Świętokrzyskie Voivodeship. Depending on the specific group, the lakes have different morphometric parameters of the lake basin and the water catchment area as well as physical and chemical properties of the water. In winter 2021, after a wave of severe frost, the thickness of the ice was measured on a selected number of lakes. The results of the tests indicate a diverse thickness of the ice caps. Karst lakes had the thickest ice caps. Riverine and aeolian lakes, on the other hand, featured similar thickness of the ice. However, it was noticed that in the case of riverine lakes, the ice cap on shores with prevailing reed was thinner than in the central parts of the lake.
Region innowacyjności: próba konstrukcji wielowymiarowego modelu analizy
Authors: Zdun Magdalena
Published: May 2022

The aim of the article is to present a novel model for the analysis of regional differentiation of innovation cultures. The research output of sociology in this area allows us to identify three strands of analysis: materialist, ideological and social. It also allows us to make inferences about cognitive reductionism associated with the adoption of a single selected perspective. This is also what the proposed model aims to counteract. It is intended to be a conceptual construct that enables a multivariate diagnosis of the regional diversification of innovation culture. At the same time, it highlights the fact, that a complete diagnosis of innovation requires an appropriate unit of analysis (region) and a related analytical category (culture). Linking together these concepts leads to constructing a model that allows us to determine the level of innovation in the modern world and its territorial differentiation. Investigating innovation in accordance with that model involves reaching the content of the different layers of culture and analysing the relationship between the different layers of innovation and the region. Each of the indicated layers can be diagnosed in a quantitative and qualitative way. This model will be built in three stages. In the first stage, a multivariate (i.e. including the material, ideological and social aspects) unit of analysis – region – will be constructed. In the second stage, a private diagnostic category, i.e. culture, will be matched to this unit. Stage three will bring the final construction of the model.

Poniższy artykuł zawiera treści związane ze znaczeniem zieleni w miastach, głównie wzdłuż ciągów komunikacyjnych. Podkreślono istotę sadzenia roślin oraz korzyści, jakie zieleń przynosi dla środowiska i człowieka. Przedstawiono wyniki badań przeprowadzonych na al. Wiśniowej we Wrocławiu, pod kątem wykorzystania dostępnej powierzchni biologicznie czynnej. Wyniki badań wykazały, że al. Wiśniowa jest mocno za- zieleniona, jednakże występuje wiele obszarów pokrytych wyłącznie trawą. Wzdłuż ulicy zaobserwowano brak zagospodarowania powierzchni biologicznie czynnej pod drzewami. Wykazano, że istotne jest wykorzystywanie każdej powierzchni biologicznie czynnej dostępnej w mieście w sposób przemyślany, w szczególności wzdłuż ciągów komunika- cyjnych będących źródłem liniowej emisji zanieczyszczeń, które wraz z emisją z pieców grzewczych i lokalnych kotłowni są główną przyczyną zanieczyszczeń powietrza w mieście.

Effects of welding parameters on the angular distortion of welded steel plates
Authors: Dogan Ezgi , Ay Mustafa , Kurtulmus Memduh , Yukler Ahmet Irfan , Etyemez Ayhan
Published: May 2022

In a welding process, distortion is inevitable and causes a significant problem. Distortion could be minimized up to a specific limit by controlling the welding parameters. The expansion and contraction of the welding metal and the adjacent base metal during the heating and cooling cycles of the welding process create thermal stresses and angular distortion in a welding joint. The welding parameters determine the geometry of a weld bead. The form of the weld bead is vital in the angular distortion of butt welded plates. This article discusses the influence of some flux-cored arc welding process parameters such as shielding gas flow rate, weaving motion of welding electrodes, and torch angle on bead profile and angular distortion of St 37 steel plates of 10 mm thickness. The angular distortion decreases with the torch angle, but it increases with the gas flow rate. The electrode weaving motion consists of three components: the designed weld width, the vertical motion period in the welding direction, and the lateral motion speed normal to the welding direction. The angular distortion decreases with the weld width and the vertical motion period but decreases with the lateral speed.

Dependence modeling in stochastic frontier analysis
Authors: Mamonov Mikhail E. , Parmeter Christopher F. , Prokhorov Artem B.
Published: May 2022

This review covers several of the core methodological and empirical developments surrounding stochastic frontier models that incorporate various new forms of dependence. Such models apply naturally to panels where cross-sectional observations on firm productivity correlate over time, but also in situations where various components of the error structure correlate between each other and with input variables. Ignoring such dependence patterns is known to lead to severe biases in the estimates of production functions and to incorrect inference.

Published: May 2022

Justicia gendarussa Burm.f, belonging to the family Acanthaceae, is widely used for various ailments traditionally. Antioxidant, anti-arthritic, anti-inflammatory, analgesic, anticancerous, properties of the plant have been widely reported. The present study analyzed the cardioprotective effect of J. gendarussa on doxorubicin (DOX) induced toxicity in mice. Ethanolic extract of J. gendarussa was administered orally for 7 consecutive days. The alterations in oxido-reduction status, biochemical and histopathological parameters were analyzed in heart tissue. DOX increased superoxide dismutase (SOD) and catalase activities to 3.4 ± 0.5 and 3.68 ± 1 from their normal values 2.43 ± 0.8 and 2.72 ± 0.88, respectively. The increased activities of both the enzymes were found reduced to 3.12 ± 0.24 and 3.41 ± 0.65 by the treatment of the extract. Similarly, DOX elevated glutathione peroxidase (GPx) activity to 44.6 ± 3.71 from the normal level 32.33 ± 3.41. DOX decreased the glutathione (GSH) level to 15.66 ± 2.51 from the normal values 31.66 ± 4.05. Upon treatment, GPx activity and GHS level found restored. The increased lipid peroxidation 2.53 ± 0.25 of DOX was also decreased to 2.0 ± 0.34 by the extract. Histopathology observations substantiate the protective effect of J. gendarussa extract. In conclusion, DOX-induced disturbance of oxido-reduction status and histopathology of heart attenuated closer to the normal indicating the protective effect of J. gendarussa against DOX-induced toxicity in cardiomyocytes.

As small molecule drugs become harder to develop and less cost effective for patient use, efficient strategies for their property improvement become increasingly important for global health initiatives. As a new crystal engineering strategy, cocrystals have opened a new way to modify the physicochemical properties of pharmaceutical solids. Improvements in the physical properties of Active Pharmaceutical Ingredients (APIs) without changes in the covalent chemistry have been possible through the application of binary component solids. In this work, a pharmaceutical cocrystal of ascorbic acid (A) + para-aminobenzoic acid (B) and ascorbic acid (A) + paracetamol (P) cocrystal are synthesized and characterized by PXRD, DSC, and FT-IR. FT-IR indicates the kind of interactions occurring between API and coformer. The DSC thermogram for (A–B) cocrystal showed a single endothermic peak attributed to the melting temperature at 155 °C. The thermal behavior of the cocrystal was distinct with different melting temperatures from that seen with either of the individual components; this suggests the formation of a new phase. As molecular modeling is presented as a support to the experiment, a computational study using density functional theory (DFT) at the level of the WB97XD functional and 6-311 + G (d, p) basis set was carried out using the Gaussian 09 program. This theoretical study made it possible to calculate the energetic properties, the intramolecular hydrogen bonds as well as the thermodynamic properties for the two cocrystals.

In this study we investigated the production cross sections of natCu(p, x)63,65Zn, natTi(p, x)48V, natNi(p, x)55Co,61Cu and natCu(α, x)66,67,68Ga, natTi(α, x)49,51Cr, natNi(α, x)63,65Zn reactions in the low energy range using the foil activation technique. The samples were activated in vacuum at 5 MV tandem (Pelletron) accelerator installed at National Centre for Physics (NCP), Islamabad, Pakistan. The reaction products were identified with the help of off-line gamma ray spectroscopy system connected with Genie 2000 software. The data analysis revealed the production of different radioisotopes that have valuable importance in monitoring charged-particle beams and medical applications. The measured results were verified by comparing them with earlier evaluated data as well as with the theoretical values given in the TENDL-library based on TALYS-1.9 code calculations.
Intersemiotic projection and academic comics: towards a social semiotic framework of multimodal paratactic and hypotactic projection
Authors: Zeng Lei , Zhu Xinyu
Published: May 2022

Intersemiotic projection is one of the most common configurations in the knowledge construction process of academic comics. Although previous studies address some general features of intersemiotic projection, further research on interdependency relations of intersemiotic projection is needed in order to map out the whole system. This study, based on the social-semiotic approach to multimodal studies, proposes a systemic framework of image-text paratactic and hypotactic projection in academic comics. This framework identifies three sub-categories of paratactic projection and hypotactic projection, respectively: (1) Emergent, (2) Adjoined, (3) Sequential, (4) Compound, (5) Subsumed, and (6) Fused. The use of these projection configurations contributes to the realization of the communicative purposes of academic comics to evidence, exemplify, emphasize, explain, elaborate, and visualize the discussed knowledge. This research attempts not only to contribute to the theoretical development of multimodality from the social-semiotic perspective by refining and enlarging the multimodal hypotactic projection framework but also to provide an effective and applicable tool for comics analysis.

Aromatic plants embrace volatile compounds with efficiency in treating different diseases. In Jordan, Syzygium aromaticum flower buds (clove) are extensively used as folk medicine without awareness of its bio-safe dosage. Herein, clove buds were hydrodistilled using the Clevenger apparatus, and the resulting essential oil (CEO) was analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). The antibacterial activity was evaluated against tested bacterial strains by agar diffusion test and micro-broth dilution assay. The antioxidant capacity was assessed using DPPH radical scavenging assay, while the cytotoxic potency was unraveled by determination of its anti-proliferative activity against MDA-MB-231 breast adenocarcinoma and normal Vero cell lines. CEO yield was 5.7 ± 1.3% (w/w); encompassed 24 volatile ingredients with eugenol as the principal compound (73.41%). The CEO inhibited the growth of both Gram-positive and Gram-negative bacterial test strains, causing the formation of 13.7 ± 1.5–17.3 ± 0.6 mm and 11.7 ± 1.5–20.7 ± 1.2 mm inhibition zones, respectively with MIC 1.25–5 μL/mL. Moreover, it showed antioxidant activity with IC50 0.0016 ± 0.0001 μL/mL (1.6 ± 0.1 μg/mL, 2.98 ± 0.4 µg Trolox®/µg CEO). Intriguingly, the CEO was cytotoxic against both cancerous and noncancerous cell lines at IC50 of 0.25 ± 0.02 μL/mL and 0.18 ± 0.01 μL/mL, respectively. Herein results unveil the potential application of CEO as a pharmaceutical remedy with considering its bio-safe dosage.
Trunk Neuromuscular Function and Anterior Cruciate Ligament Injuries: A Narrative Review of Trunk Strength, Endurance, and Dynamic Control
Authors: Song Yu , Li Ling , Dai Boyi
Published: May 2022

Trunk strength, endurance, and dynamic control may have an effect on anterior cruciate ligament (ACL) injury rates and biomechanical ACL loading variables during athletic tasks. Individuals responsible for training athletes at risk of ACL injuries should implement training programs that address these components of athletic performance. In ski racers, deficits in trunk flexion/extension strength and decreased trunk flexion/extension strength ratios have been identified as ACL injury risk factors. Trunk strength training alone is not sufficient to decrease biomechanical ACL loading, and there is no clear association between trunk endurance and ACL injury risks. Trunk dynamic control training may improve trunk and knee movements associated with decreased ACL loading during athletic tasks. Dynamic, unanticipated, and perturbed trunk functional assessments and training are recommended to challenge the trunk more during athletic tasks. Injury prevention programs should involve exercises using unstable surfaces, sports-related dual tasks, and perturbations to address trunk dynamic control. More investigation is still needed to further understand the associations between trunk neuromuscular functions and ACL injury risks during athletic tasks.

Inhibitory neurons take on many forms and functions. How this diversity contributes to memory function is not completely known. Previous formal studies indicate inhibition differentiated by local and global connectivity in associative memory networks functions to rescale the level of retrieval of excitatory assemblies. However, such studies lack biological details such as a distinction between types of neurons (excitatory and inhibitory), unrealistic connection schemas, and nonsparse assemblies. In this study, we present a rate-based cortical model where neurons are distinguished (as excitatory, local inhibitory, or global inhibitory), connected more realistically, and where memory items correspond to sparse excitatory assemblies. We use this model to study how local-global inhibition balance can alter memory retrieval in associative memory structures, including naturalistic and artificial structures. Experimental studies have reported inhibitory neurons and their subtypes uniquely respond to specific stimuli and can form sophisticated, joint excitatory-inhibitory assemblies. Our model suggests such joint assemblies, as well as a distribution and rebalancing of overall inhibition between two inhibitory subpopulations, one connected to excitatory assemblies locally and the other connected globally, can quadruple the range of retrieval across related memories. We identify a possible functional role for local-global inhibitory balance to, in the context of choice or preference of relationships, permit and maintain a broader range of memory items when local inhibition is dominant and conversely consolidate and strengthen a smaller range of memory items when global inhibition is dominant. This model, while still theoretical, therefore highlights a potentially biologically-plausible and behaviorally-useful function of inhibitory diversity in memory.
Digital Perspectives on Overland Travel and Communications in the Exarchate of Ravenna (Sixth through Eighth Centuries)
Authors: McMahon Lucas
Published: May 2022

The arrival of the Langobardi to Italy disrupted centuries-old Roman overland communication networks. When the political situation stabilized around 600 CE, Rome and Ravenna, still under East Roman control, were linked by a thin tendril of territory encapsulating a militarized travel zone between the two cities, the “Byzantine Corridor.” This study uses GIS analysis, particularly least-cost path techniques, to provide further perspectives on how communication was managed between Rome and Ravenna. This technique forms the basis of a movement model in order to calculate some approximate travel times between the two cities. Having some sense of the speed and ease at which the two cities could communicate with each other creates a baseline on which to understand how decisions of political importance were made and how the geographies of communication were reconfigured in late antique and early medieval Italy.
Ethanolamine‐phosphate on the second mannose is a preferential bridge for some GPI‐anchored proteins

Glycosylphosphatidylinositols (GPIs) are glycolipids that anchor many proteins (GPI‐APs) on the cell surface. The core glycan of GPI precursor has three mannoses, which in mammals, are all modified by ethanolamine‐phosphate (EthN‐P). It is postulated that EthN‐P on the third mannose (EthN‐P‐Man3) is the bridge between GPI and the protein and the second (EthN‐P‐Man2) is removed after GPI‐protein attachment. However, EthN‐P‐Man2 may not be always transient, as mutations of PIGG, the enzyme that transfers EthN‐P to Man2, result in inherited GPI deficiencies (IGDs), characterized by neuronal dysfunctions. Here, we show that EthN‐P on Man2 is the preferential bridge in some GPI‐APs, among them, the Ect‐5’‐nucleotidase and Netrin G2. We find that CD59, a GPI‐AP, is attached via EthN‐P‐Man2 both in PIGB‐knockout cells, in which GPI lacks Man3, and with a small fraction in wild‐type cells. Our findings modify the current view of GPI anchoring and provide a mechanistic basis for IGDs caused by PIGG mutations.

Authors: Navas Panadero Alexander
Published: May 2022

El objetivo de este trabajo fue conocer la percepción y conocimiento de pequeños productores sobre el comportamiento del clima, su efecto en la producción de leche y las prácticas que permiten la adaptación a este comportamiento. El estudio se desarrolló en Carmen de Carupa y Suesca (Cundinamarca, Colombia) con 40 productores que compartieron su conocimiento a través de una entrevista semiestructurada. Se indagó por las causas del cambio climático, eventos que afectan la producción de leche, cambios en el clima en los últimos años y estrategias que permitan su adaptación. Se determinó el índice temperatura humedad, precipitación, producción de leche y calidad del forraje. Se utilizó el análisis de frecuencia y de componentes principales mediante el programa Infostat®. Los productores consideraron la deforestación como principal causa de cambio climático, percibieron cambios en el clima y reconocieron sequías, heladas y altas temperaturas como eventos de mayor impacto negativo en la producción de leche, percibieron cambios en las épocas de lluvias y menor precipitación, sequías más prolongadas, incremento en la temperatura y heladas durante el año. Asimismo, consideraron importantes las prácticas agroecológicas para adaptarse a la variabilidad climática. La producción de leche presentó una relación positiva con la digestibilidad y proteína cruda, una relación negativa con la fibra detergente neutra y fibra detergente ácida, al igual entre la precipitación con la producción de materia seca y de leche, lo que correspondió con algunas de las percepciones los productores. Se concluye que los pequeños productores de leche tienen percepciones y conocimientos del comportamiento del clima, su impacto en la producción de leche y prácticas que permiten la adaptación a condiciones de estacionalidad y variabilidad climática.
