Encampment against Enclosure
Authors: Hodali Suleiman 
Published: December 2024

Abstract
This article examines the emergence of student encampments protesting university complicity with Israeli occupation of Palestine. It analyzes these encampments as sites of resistance, highlighting their disruption of university space and their challenge to administrative authority. The encampments’ use of barricades and their occupation of central campus locations are interpreted as acts of counter-enclosure, reclaiming space and challenging traditional power structures within the university. Furthermore, the article critiques administrative attempts to discredit and dismantle these encampments, arguing that such efforts reflect a broader struggle over the definition and control of “community” within the university setting. By linking the student protests to historical examples of enclosure and resistance, the article ultimately emphasizes the encampments’ significance as expressions of collective action and their potential to reshape the university's role in struggles against settler colonialism.
Nozzle Flowrate Modulation Capability of PWM Valves Operated at High Frequencies and Pressures

Published: December 2024

HighlightsPWM valves were tested for accurate modulation of hollow-cone nozzle flowrates up to 40 Hz PWM frequency.Flowrates of nozzles at high pressures increased linearly as PWM duty cycles increased.Modulation frequency affected flowrates slightly but not pressure drops when liquid was passing through valves.Integrating these valves into variable-rate sprayers could potentially improve the application efficiency.Abstract.Pulse width modulation (PWM) solenoid valves are a critical component of precision sprayers equipped with crop detection sensors to achieve accurate variable-rate applications of pesticide in real time. However, the slow speed of PWM valves can impede the efficiency of high-speed detection sensors. Based on previous investigations of 12 commercially available PWM valves operated up to 50 Hz frequencies, two of the valves with the highest modulation capability were selected for continuous investigations on their flow rate modulation accuracy and pressure stability for hollow-cone nozzles. Tests were conducted with two different-sized hollow-cone nozzles controlled by each PWM valve. Variables included 4 modulation frequencies ranging from 10 to 40 Hz, 6 duty cycles (DUCs) from 10% to 100%, and 3 operating pressures (1034, 1380, and 2068 kPa). Flow rates were measured by instantaneously weighing the mass of water discharged from nozzles while pressure profiles were measured with two pressure transducers located upstream and downstream the PWM valve. In general, both PWM valves were able to modulate flow rates of the two hollow-cone nozzles up to 40 Hz modulation frequencies with limited DUC ranges even though one valve performed slightly better than the other. When the nozzles were manipulated functionally with assigned DUCs and frequencies, the flow rate modulation errors of PWM valves ranged between 0% and 35%, while the average root mean square errors (RMSEs) ranged between 6.9% and 14.7% for combinations of all pressures, frequencies, and DUCs tested. Thus, there would be potential benefits to integrating these two high-frequency PWM valves into precision orchard sprayers operated at high pressures to further improve the variable-rate application accuracy.

The scattering and absorption of light within biological tissue severely limits the penetration depth of optical imaging techniques. Recently, it has been found that water-soluble, strongly absorbing dye molecules, such as tartrazine, can achieve in vivo tissue transparency by increasing the refractive index of aqueous components in tissue, as predicted by the Lorentz oscillator model and Kramers–Kronig relations. In this study, we topically applied absorbing dye molecules to the abdominal skin of pigmented and nonpigmented mice to enhance the penetration depth of optical coherence tomography (OCT) and photoacoustic microscopy (PAM). In both types of mice, the penetration depth of OCT was significantly improved using tartrazine and 4-aminoantipyrine. As predicted by the Kramers–Kronig relations and absorption spectra of the dyes, mice treated with 4-aminoantipyrine showed significantly improved penetration depth compared to mice treated with tartrazine for the PAM system with 532 nm excitation. These findings further demonstrate the use of absorbing dye molecules for achieving tissue transparency to enhance the penetration depth of depth-resolved optical imaging modalities in skin, thus accelerating the translation of these technologies in clinical areas, such as dermatology.

The popularity of the blue swimming crab (Portunus pelagicus) has led to significant overfishing. Aquaculture offers a potential solution to reduce fishing pressure, given that P. pelagicus is relatively easy to hatch, has high fecundity, a short larval duration, and rapid growth. However, knowledge about feed preferences and feed-use efficiency in P. pelagicus is limited. This study compared the effectiveness of three locally available feeds. A total of 160 juvenile P. pelagicus were divided into five repetitions across four diet groups: PPV (shrimp pellets + Perna viridis flesh, crude protein = 45 %), PAI (shrimp pellets + Acetes indicus, crude protein = 45 %), P100 (shrimp pellets, crude protein = 30%), and P150 (shrimp pellets at 150% of the dry matter requirement, crude protein = 45%, iso-protein to both PPV & PAI). The experiment consisted of three phases: a one-week pre-trial to determine feeding rates, followed by a six-week culture period (Period-1) and an eight-week culture period (Period-2). Body weight and survival were measured biweekly, feed amounts were adjusted accordingly, and costs were recorded. Survival rates and feed conversion ratios were similar across all diets. Crab growth was lower in Period-2 than in Period-1 across treatments. The specific growth rates for PPV, PAI, and P150 were comparable, while P100 resulted in lower growth. The cost of PPV was higher than that of PAI, P100, and P150, with the economic feed conversion ratio for P100 and P150 outperforming PPV and PAI. Shrimp pellets proved to be an efficient feed for the grow-out phase of blue swimming crabs, though pellet size should match the crab’s size.
Multimodal creativity and identity in digital discourse: meme practices in China
Authors: de Groot Freek Olaf 
Published: December 2024

Abstract
This paper studies how internet memes in the context of China are the result of complex semiotic remixing practices and how these multimodal practices offer opportunities for identity work. It offers a situated perspective on the processes that underlie the creation of Chinese memes (Biaoqingbao), the ways in which these memes mediate the digital practices of members in a student community, and how these students find opportunities for identity work. This study takes a social semiotic (Kress, Gunther R. 2010. Multimodality: a social semiotic approach to contemporary communication. Taylor & Francis) and Mediated Discourse Analysis approach (Scollon, Ron. 2001. Mediated discourse: The Nexus of practice. Routledge; Scollon and Scollon 2004; Norris, Sigrid & Rodney H. Jones. 2005. Discourse in action: introducing mediated discourse analysis. London: Routledge) to analyze biaoqingbao as the mediate the social interaction within a light community. The data was collected using a form of digital ethnography. The memes studied in the current paper are unique in two ways. First, they combine both local and global people, places, objects and discourses deploying both Chinese and English texts and effectively create semiotic trajectories between highly localized digital meme practices and more global mainstream meme practices. Second, the practices of producing, sharing and remixing these memes are exclusively situated in a distinct light community and offer important opportunities for multimodal identity performance.
Exploring Iranian Identity: A Contrastive Analysis of Western Literary Perspectivesversus Iranian Art of Dance
Authors: Pondelíková Ivana , Majdáková Veronika 
Published: December 2024

The concept of identity is currently one of the most frequently examined in cultural studies. Identity refers to the identification of an individual with a certain unit based on signs that he/she consciously or subconsciously accepts as his/her own. There are two main currents in identity research: primordialism (essentialist approach) and instrumentalism (constructivist approach). In today’s individualized society, there is a shift in emphasis from primordiality, i.e. from that side of identity that is given, permanent, inherited, fixed, to instrumentality, i.e. to such a basis of identity that a person chooses, creates, or selects. The research focuses on Iranian identity and its reflection in Western literature and the Iranian art of dance. Iran has an exceptional position in its region and influences global events with its policy. The question is what allowed the Persians to remain Persians for more than two and a half millennia. Persian identity is expressed mainly in spiritual power, poetry, and religion. The Persians gave the world poetry, miniatures, and carpets. From the point of view of production prosperity, all useless things. But that is how they express themselves. They gave the world what did not serve to make life easier but to make it more beautiful (Kapuściński, 2016, p. 153). The empirical part of the research is divided into two parts. In the first part of the research, the authors focus on expressing Iranian identity in their traditional and modern dance. The Persian “classic” is characterized by an expressive movement of the upper part of the body, delicate movements of the shoulders and palms, and eloquent facial expressions. The dance is very poetic and often depicts scenes from Persian poems. The second part of the research focuses on examining how Iranian identity is reflected in Western literature. The study of Iranian identity is based on Azar Nafisi’s Reading Lolita in Tehran (2003), who is a representative of Iranian anglophone immigrants, as well as on an unintentional tetralogy of novels by Betty Mahmoody, the author of the novels Not without my Daughter (1987) and For the love of a child (1992), her daughter Mahtob, the author of My Name is Mahtob (2013), and Moody, Mahmoody’s ex-husband and Mahtob’s father, the author of Lost without my Daughter (2013). The culture of a nation is expressed in the identity of its inhabitants, and literature and the art of dance contribute to its understanding.
Citizenship in Lithuanian Lexicographical Sources, Youth Worldview, and Media Texts
Authors: Smetona Marius 
Published: December 2024

The concept of citizenship (civic sense) has not yet fully crystallised, which is why different aspects are emphasised in academic literature and public discourse. Attempts are made to compare and associate it with other concepts, such as nationality or patriotism, which are often used synonymously in various contexts. From a linguistic perspective, the concept of citizenship has not been thoroughly examined. Therefore, the aim of this article is to explore the concept of citizenship in Lithuanian dictionaries, public media texts, and the responses of young people to the question: What does citizenship mean to you? The concept of citizenship is closely related to another concept—namely, the state—where legal, cultural, social, and political elements are interconnected. The state provides its citizens with rights and duties, and a citizen must be able to use and defend the rights and freedoms granted, as well as actively participate in public life with the ultimate goal of contributing to the well-being of Lithuania. Students emphasise that the concept is complex and involves not only an individual’s relationship with the state but also relationships between people. However, both in youth responses and in public discourse, the key aspect is that citizenship is seen as a value, the components of which are reflected in its cognitive definition. Despite the introductory thoughts stating that citizenship and patriotism are not identical, for young people these concepts are intertwined and share many common aspects. In public discourse, there is a strong emphasis on the importance of nurturance of citizenship, which requires continuous effort. As a result, various initiatives, competitions, lessons, and programs are offered. The research concludes that the cognitive definition of citizenship embraces respect for the state, its language, symbols, history, culture, and traditions, as well as for other citizens and differing opinions; a duty to the state (defence, involvement in public life, voting, paying taxes, restraining misbehaviour); working for the state; love for the country; and self-sacrifice for it. Typically, the meaning of a word is looked up in dictionaries regarded as the most reliable lexicographical sources. The study shows that there is a need to expand dictionary definitions or elaborate on this concept in the upcoming “Dictionary of Standard Lithuanian”, so that society can recognize the broader content of the concept of citizenship. It is agreed that citizenship is a cultivated value, and its content heavily depends on who is involved in the educational process. Therefore, it is essential for linguists and language institutions to engage in the citizenship development program so that young people can see that citizenship is not just about defence; it also includes language, as well as cultural and ethnic aspects.
An Improvement Project to Lower Pneumothorax Rates in Neonates Born at 36 Weeks’ Gestational Age or Beyond
Authors: Sandall Jenica , Hilborn Craig , Welty Stephen 
Published: December 2024

OBJECTIVE
Our institutional data revealed high pneumothorax rates in term neonates resuscitated in the delivery room (DR). Other studies have reported that high rates of continuous positive airway pressure (CPAP) in the DR are associated with increased pneumothorax rates. We sought to test the hypothesis that quality improvement efforts to reduce the use of CPAP in the DR would be associated with a reduced incidence of pneumothorax.

METHODS
We performed a series of interventions to make minor revisions to our DR respiratory care algorithm focusing on optimizing CPAP use by providing education to the DR team to the revisions. For neonates born at 36 weeks of gestation or beyond, we evaluated the use of CPAP in the DR and the number of births between pneumothorax events before and after the algorithm was implemented. We used statistical process control charts to assess improvement.

RESULTS
CPAP utilization in the DR for infants 36 weeks or older decreased from 3.4% to 1.0%. Frequency of pneumothorax decreased, with births between pneumothorax events increasing from 293 to 530. We found no increase in the number of neonates requiring a higher level of care with respiratory distress.

CONCLUSION
We found that a reduction in the use of CPAP in DR was associated with a decrease in the rate of pneumothorax without an increase in neonates requiring additional care with respiratory distress.

Objetivos. Evaluar el efecto de la periodontitis apical (PA) inducida en ratas Wistar sobre el tejido renal examinado histológicamente. Materiales y métodos. Fueron utilizadas 14 ratas Wistar macho, de 12 semanas y 250 gramos promedio. La PA fue inducida con la exposición pulpar de los primeros molares superiores e inferiores utilizando una fresa esférica #1011 HL en alta rotación. Las lesiones se dejaron expuestas al medio bucal por un periodo de 7 semanas. La presión arterial fue medida mediante el método de pletismografía del manguito de la cola a partir de la cuarta semana. Fue realizada la disección del riñón para análisis histológico (H&E). Fue utilizada la prueba de Mann-Whitney y t de Student para datos no paramétricos y paramétricos, respectivamente, con un nivel de significancia del 5%. Resultados. Se observó un aumento estadísticamente significativo tanto en el área del espacio de Bowman como en el área del corpúsculo renal en el grupo PA (p<0,05). El grupo con PA presentó mayor porcentaje de tejido renal con infiltrado inflamatorio, pero sin diferencia significativa. La presión arterial no sufrió modificaciones durante el periodo experimental y no fue identificada diferencia entre los grupos. Conclusiones. La inducción de PA en ratas Wistar resultó en modificaciones significativas de ciertos parámetros histológicos renales, sugiriendo unaposible interacción entre la PA y el tejido renal que requiere de investigaciones adicionales.

Objective. To evaluate the association between multimorbidity and mental health in adults aged 30 to 69 years. Materials and methods. Secondary data analysis of a population-based study conducted in theperi-urban area of Tumbes in the northern coast of Peru. The dependent variables were: depressive symptoms, using the PHQ-9; anxiety symptoms, using the Goldberg scale; and perceived stress, assessed withthe Cohen’s 14-question scale. The exposure variable was the presence of multimorbidity (presence or not of two or more chronic conditions and the number of chronic conditions). We assessed associations using crude and adjusted Poisson regression models. Results. Data from 1600 participants were analyzed, mean age was 48.1 years (SD: 10.5), and 50.4% were women. The prevalence of multimorbidity was 15.9%, 23.3% presented depressive symptoms, 42.0% anxiety symptoms and 31.4% had high levels of perceived stress. The multivariable model showed that multimorbidity was associated with a higher prevalence of depressive symptoms (61%, 95%CI: 32% - 98%), anxiety symptoms (46%, 95%CI: 28% - 66%) and high (22%, 95%CI: 14% - 33%) but not moderate levels of perceived stress (6%; 95%CI: 0% - 12%). A higher number of chronic conditions was associated with higher prevalence of depressive symptoms, anxiety symptoms, and perceived stress levels. Conclusions. The presence of multimorbidity is associated with a higher prevalence of depressive symptoms, anxiety symptoms, and perceived stress levels. Our results suggest the need for adequate mental health management in patients with multimorbidity.

In order to evaluate adherence to colorectal cancer (CRC) screening among members of the Health Plan of the Hospital Italiano de Buenos Aires in Argentina, we conducted a retrospective cohort study using secondary data from the electronic medical record. We included all members over 50 years of age during the period 2008-2022. We assessed the number and type of screening tests performed and the proportion of members covered for screening. We analyzed 112,112 participants, with a median age of 58.6 years and a follow-up time of 8.6 years. Colonoscopy was the most commonly used test. The maximum coverage reached was 47.1% in December 2022. In conclusion, adherence to CRC screening was suboptimal, as was the method used. This information can be used for the design of a multicomponent intervention.
