Published: January 2022

We describe a patient who was diagnosed with multiple tubulleuvillous adenomas with focus of high-grade tubular dysplasia all over the colonic mucosa, discovered during a colonoscopy performed during an episode of melena. Genetic testing has identified a germline truncating mutation at the codon (5q22.2) of the adenomatous polyposis (APC) gene. This mutation is localized in the alternately spliced region of exon 12, a region which is associated with an attenuated familial adenomatous polyposis (PAFA) phenotype. Our patient had no extracolic manifestations of PAFA and none of her relatives had a history of rectocolic polyposis. Treatment consisted of colectomy with ileorectal anastomosis. PAFA is an ill-defined condition of unknown prevalence and penetrance, requiring individual treatment and lifelong monitoring. It is essential to identify these patients with a view to setting up appropriate endoscopic surveillance at an early age in family members carrying this mutation, due to the marked intra-family phenotypic variance.

Newspaper Language in Representing Ethnic Violence: Textual Analysis of Kompas dan Republika Newspapers
Authors: . Prayudi
Published: January 2022

The reconceptualization of ethnicity came to its peak when the New Order regime introduced the policy of â€˜sukuâ€™ (ethnic), â€˜agamaâ€™ (religion), â€˜rasâ€™ (racial) or â€˜antar golonganâ€™ (inter-group). The policy, known as SARA, was meant to limit and control public interpretation over all socio-political conflicts that may endanger national stability and to restrict languages used in the news media. The policy had became the main foundation of all government policies related to society. Conflicts should be avoided and difference within society was intolerable. The Indonesian press then faced a dilemma when it came to reporting issues of ethnicity. On one side, they had an obligation to report the news to public; on the other side, the concept of SARA had become an unwritten law to restrict the press from reporting the issue. Further, the government could revoke the publishing permits without any warning it thought that the press had broken the law. The objective of the research was to define and analyze the usage of language in national newspapers in representing ethnicity issues. The analysis focused on the 1997 ethnic violence in West Kalimantan.

The complexcity of the mediaâ€™s problem in determining media policy can not be solved only by structural approach. The cultural approach is also needed in getting people participation and involvement to solve that problem. When the effect of media become an important issue in the relationship between media and the public, the media should not only be regulated, but the public should be involved and given the opportunity to play important role making the media to be part of public life and helping the public to solve their life. Peopleâ€™s empowerment in this cultural approach can be conducted through the program of media literacy. This movement as a public power and identity certainly has influence to the media.

Virtual Reality Technology and Speech Analysis for People Who Stutter
Authors: Al-Nafjan Abeer , Alghamdi Najwa , Almudhi Abdulaziz
Published: January 2022

Virtual reality (VR) technology provides an interactive computer-generated experience that artificially simulates real-life situations by creating a virtual environment that looks real and stimulates the user’s feelings. During the past few years, the use of VR technology in clinical interventions for assessment, rehabilitation and treatment have received increased attention. Accordingly, many clinical studies and applications have been proposed in the field of mental health, including anxiety disorders. Stuttering is a speech disorder in which affected individuals have a problem with the flow of speech. This can manifest in the repetition and prolongation of words or phrases, as well as in involuntary silent pauses or blocks during which the individual is unable to produce sounds. Stuttering is often accompanied by a social anxiety disorder as a secondary symptom, which requires separate treatment. In this study, we evaluated the effectiveness of using a VR environment as a medium for presenting speech training tasks. In addition, we evaluated the accuracy of a speech analyzer module in detecting stuttering events.

When someone uses a wheelchair, there is still the possibility of an accident to the user, such as when the user suddenly falls down from the wheelchair or the user falls down along with the wheelchair. For notification of emergency conditions for wheelchair users, an alarm system is designed that can send messages to the intended mobile number. The system is designed using Wemos D1 mini, Ultrasonic, MPU-6050 and Proximity E18-D80NK sensors. The conclusion from the measurement and test results are: the value read by the MPU-6050 sensor is taken one axis for each direction when the wheelchair was falling down, Y≤180o for left falling down, X≤50o for right falling down, Z≤65o for forward falling and Z≥140o for backwards falling down. The Ultrasonic sensor works well for detecting the presence of user’s legs and the E18-D80NK proximity sensor works well for detecting the position of the user who is sitting in a wheelchair. Receiving notifications through the BLYNK server works well, not affected by distance provided there is an internet connection connected to the device.

Published: January 2022

Nitrogen (N) is an important nutrient for the growth and development of rice plants, required in large quantity and often limiting factor of rice yields. The research was to understand the different sources and levels of nitrogen in rice plant on the activity of N assimilation enzymes, including nitrate reductase (NR), glutamine synthase (GS) content, glutamate synthase (Gogat) content, content, ammonium (NH4+) and nitrate (NO3-) content on the leaves. Paddy (Ciherang variety) was grown in sand media containing Hoagland solution with different sources (ammonium and nitrate) and levels (0.4, 0.8, 1.6, 3.2, 6.4, and 12.8 mM) of nitrogen. Nitrogen assimilation was observed from leaves at one month of age. The NR activity increased on both Nitrogen sources, it was a higher activity in media contained nitrate. Also, the activity of GS showed higher in media contains nitrate, but its activity was decreased after application 1.6 mM of nitrate and 3.2 mM of ammonium. Western blot analysis of GS1 and GS2 showed that the band pattern of protein was similar to these enzyme activities. Nitrate content in leaves gradually increased in both sources of nitrogen and higher than 3.2 mM ammonium application caused an increase in ammonium content in leaves, but the nitrate content decreased. This research resulted that the available source of N for rice was in nitrate form, easily by the rice plants during the growth stage.

Decreased rice productivity due to high iron concentrations especially in the vegetative phase, this causes the morphological character of rice to be affected until the metabolic process is disrupted. This study used 6 varieties, namely Batu Tegi, Inpara 9, Situ Patenggang, Inpara 8, Hawarabunar and Inpago 8, with iron concentrations of 0 and 250 ppm. The seeds were germinated for 3 days, then planted in Kimura B 10% nutrient culture media for 9 days, for 2 weeks then each week the media was changed to 100% Kimura B solution with the addition of 250 ppm iron concentration which was sampled every week until the 35th day. The results of the analysis of variance of the variables of plant height and root length showed that the combination Inpara 8-01 was the best combination and had a significant effect compared to other combinations with an average value of 61.31 cm and 30.77 cm. In the variable number of leaves the best average value was found in the combination of Batu Tegi-01 and Inpara 9-01 which had a significant effect compared to other treatments with an average value of 5.87 strands and 9.60 strands, respectively. On the stem dry weight variable, the combination of Hawarabunar-250 ppm Fe had a significant effect on other treatment combinations with the highest value of 0.17 g and the lowest value of treatment combination Inpara 9-250 ppm with a value of 0.08 g. Based on the results of treatment with 250 ppm Fe stress on plant morphological characters, the Hawarabunar variety had the best response in tolerating Fe stress, while the Batu Tegi variety was the lowest in tolerating Fe stress.

In the hatchery of white shrimp larvae, there are some problems, such as a decreased water quality and diseases caused by bacteria which cause a decrease in shrimp growth. The solution to reduce these problems is by applying synbiotics. This research aimed to make an innovative synbiotic formula for the absolute length growth and survival rate of white shrimp larvae (Litopenaeus vannamei) as well as  the total number of bacteria and the number of Vibrio sp. In this study, there were four treatments, as follows: C-: negative control (without synbiotic application) C+: positive control (commercial synbiotic) P: probiotic 2.5 x 105 cfu/ml and prebiotic 1,5 ppm Q: probiotic 5 x 105 cfu/ml and prebiotic 1 ppm R: probiotic 7,5 x 105 cfu/ml and prebiotic 0,5 ppm S: probiotic 106 cfu/ml and prebiotic 2 ppm, each treatment with four repetitions. This research was set up in a completely randomized design experiment using twenty-four plastic tanks with 50 L total volume filled with 20 L sterile sea water and stocked with 4,000 nauplii in the PT. Citra Larva Cemerlang hatchery, Kalianda, Lampung. Variables observed in this research were survival rate, absolute length growth, total bacterial and Vibrio sp. counts, and water quality in the white shrimp larvae (Litopenaeus vannamei). The results showed that the best survival rate is in treatment S (probiotic 106 cfu/ml and prebiotic 2 ppm) (87.7%), the highest absolute length growth is in treatment P (3.8 mm), the highest total bacteria was in treatment S (11.1 log cfu/ml), and the best total Vibrio sp. is in treatment S (3.5 log cfu/ml). Water quality of the six treatments shows results that are still in normal conditions following Indonesian National Standard SNI 7311: 2009.

Oil palm has a high economic value since it is one of the highest vegetable oil-producing plants compared to other oil-producing plants. The provision of good planting material for oil palm plantations is one of the determining factors to increase productivity. The parent Pisifera type of oil palm is important to develop the high-yielding oil palm Tenera varieties. The provision of oil palm material could be done through generative system with seeds and also could be done through vegetative approaches using tissue culture techniques. It aims to get plants that are genetically the same as their parents (true to type). The purpose of this study was to see the effect of different type of tissue culture media and plant growth regulators (PGR’s) on the callus induction stage of Pisifera type oil palm. The results show that the treatment using Murasige and Skoog (MS) culture media is able to give a better effect when compared to the use of Eeuwens and Blake (Y3) basic media. While the use of PGR treatment (H6 = NAA 6 mg/l + 2.4-D 0.5 mg/l) showed a callus growth percentage of 76%, which was better than (H1 = Kin 0.1 mg/l + 2.4-D 100 mg/l) by 42%.

The mangrove area of the world has been decreasing and Indonesia has lost 1.6 million ha of mangrove during the period 1980-2005. In 2015 the status of Indonesia's mangroves was 3.5 million ha with 48% in good condition and 52% in degraded conditions. Therefore, mangrove forests should be conserved properly and utilized sustainably. Assessment of the status of mangrove conditions is essential in conservation planning and management so that it can be done better. However, the method for assessing the condition of mangrove forests is still diverse and has not been standardized, so a literature review and review of how to assess the condition of mangrove ecosystems from various literature needs to be done. The results of the study of various literatures, in general there are two types of assessments. The first assessment used canopy density indicators, tree density, structure and composition of vegetation including diversity index and environmental parameters which are used singly or a combination of some or all parameters and some that be correlated with ecological integrity. For the second assessment, using a comparison between the existing mangrove forest and the potential area to be overgrown with mangroves. There is a difference when assessing the potential area, there is the opinion of the area potentially seen by the status of the area whether or not the forest area, from the landsystem, the level of abrasion, pond area and the comparison of the coastline length overgrown with mangrove with a total coastline length. Both assessments with each indicator can be used in accordance with the objectives of the assessment of the condition.

Deriving some properties of Stanley-Reisner rings from their squarefree zero-divisor graphs
Authors: NIKSERESHT Ashkan
Published: January 2022

Let ΔΔ be a simplicial complex, IΔIΔ its Stanley-Reisner ideal and R=K[Δ]R=K[Δ] its Stanley-Reisner ring over a field KK. In 2018, the author introduced the squarefree zero-divisor graph of RR, denoted by Γsf(R)Γsf(R), and proved that if ΔΔ and Δ′Δ′ are two simplicial complexes, then the graphs Γsf(K[Δ])Γsf(K[Δ]) and Γsf(K[Δ′])Γsf(K[Δ′]) are isomorphic if and only if the rings K[Δ]K[Δ] and K[Δ′]K[Δ′] are isomorphic. Here we derive some algebraic properties of RR using combinatorial properties of Γsf(R)Γsf(R). In particular, we state combinatorial conditions on Γsf(R)Γsf(R) which are necessary or sufficient for RR to be Cohen-Macaulay. Moreover, we investigate when Γsf(R)Γsf(R) is in some well-known classes of graphs and show that in these cases, IΔIΔ has a linear resolution or is componentwise linear. Also we study the diameter and girth of Γsf(R)Γsf(R) and their algebraic interpretations.
On I-finite left quasi-duo rings
Authors: HOROUB Ayman M. A. , NICHOLSON W. K.
Published: January 2022

A ring is called left quasi-duo (left QD) if every maximal left ideal is a
right ideal, and it is called I-finite if it contains no infinite orthogonal
set of idempotents. It is shown that a ring is I-finite and left QD if and
only if it is a generalized upper-triangular matrix ring with all diagonal
rings being division rings except the lower one, which is either a division
ring or it is I-finite, left QD and left `soclin' (left QDS). Here a ring is
called left soclin if each simple left ideal is nilpotent. The left QDS
rings are shown to be finite direct products of indecomposable left QDS
rings, in each of which 1=f1+⋯+fm1=f1+⋯+fm where the fifi are
orthogonal primitive idempotents, with fk≈flfk≈fl for all k,l,k,l,
and ≈≈ is the block equivalence on {f1,…,fm}.{f1,…,fm}.A ring is shown to be left soclin if and only if every maximal left ideal is

“Daft naff Scottish things”: Stuff, Waste and Memory Objects in Jackie Kay’s Trumpet
Authors: BORBELY CARMEN
Published: January 2022

Guided by new materialist approaches to the memory of loss, this reading of Jackie Kay’s 1998 novel Trumpet surveys the affective permutations registered by different objects of remembrance in the Scottish-Nigerian writer’s fictional account of mourning. Exploring several material figurations of Black Scottishness in Kay’s writings, the essay derives its main theoretical framework from studies on blended subject-object ontologies, including Bill Brown’s critique of thingness, Maurizia Boscagli’s notion of the disruptive agency of stuff, and Mel Y Chen’s view of matter’s animacy, and discusses how the novel latches onto the role of things in anchoring memory and in helping humans work through bereavement.
The Future as a Scenario of Hospitality in Ali Smith’s There But For The
Authors: POPA ANDREI BOGDAN
Published: January 2022

The purpose of this essay is to demonstrate how Ali Smith’s novel There But For The (2011) foregrounds a temporality in which the scenario of hospitality is encoded into the characters’ perception of the future, while the welcoming scenarios in which they engage are themselves marked by the awareness of futurity. To this end, I rework Levinas’s equation of the future as the Other, as well as Derrida’s notions of conditional and unconditional hospitality, of the future as the expected/unexpected event, and of “choratic space.” The subsequent analysis of the novel proves how these notions are thematized both through the characters’ inner and intersubjective discourse, and via the authorial construction of imagery and the deictics of the spaces they inhabit. As such, the characters’ conversations bear the marks of an uncertain causality springing from the welcoming scenario; attitudes towards futurity are faced with the disquieting awareness of the conflict between the expected and the unexpected event; while the choratic space acts as the possibility of an ethical reaction to the strangers’ singularity, through a linguistic reorientation which employs the contingency of the linguistic sign as a site for hospitality.
“In came the self-evident and luminous little mess”: Ethical Life Writing in Muriel Spark’s Loitering with Intent
i
Authors: POPA-PETRAR PETRONIA
Published: January 2022

Starting from a brief examination of Muriel Spark’s position as a Scottish novelist within the framework of her anti-essentialist, anti-authoritative aesthetics, my essay will take a seemingly abrupt, but in fact consequential turn to investigate the complex antinomies involved in her fictional representation of the lives of others. Although at home and abroad she is hailed as Scotland’s most celebrated author of the twentieth century, Spark’s writerly practice consists of regularly dismantling grand narratives or fixed, stable identities, often clashing with more localized or prescriptive views on the social and national functions of narrative. My argument, however, is that it is the very unease of her “Scottishness” that acts as one of the foundations of her literary ethics, embodied in her acute awareness of the antinomies involved in textualizing the lives of others. Spark’s shrewdly metafictional Loitering with Intent (1981) openly thematizes both the obligation, and the risks of telling one’s own and other people’s stories, performing a radical ethics of narrative alterity through its staging of the enmeshments of writing, (auto)biography and experience.
Violence, Innocence and Redemption in Irvine Welsh’s Chemical Mythos
Authors: ZAMFIRESCU ANDREI-CĂLIN
Published: January 2022

Scottish author Irvine Welsh has crafted an internally cohesive cosmology, grounded in mapping a somewhat loosely defined “chemical generation” that helped spearhead a personal brand of anti-Thatcherite counterculture (with an especially heavy focus on the marginalized, disgruntled and boisterous youths of Edinburgh). Examining some of the writer’s most recent and lesser-known works, my essay will argue that a series of archaic mythical patterns, symbols and cosmological coordinates can be shown to guide a large number of the axioms that Welsh employs to refine his own vision of a modern, emergent mythos.
Modernism, Postmodernism and the Nature of the Times: A Conversation with Randall Stevenson
Authors: NEAGU ADRIANA
Published: January 2022

The interview offers a comprehensive, paradigmatic overview of the experience of literary modes within the broad frameworks of modernity and postmodernity. It invites reflection and rethinking of epistemic change from a major literary historian and theorist whose work in the Anglo-American context has become synonymous with the examination of temporality, historicity, and poeticality in twentieth century experimentation with form. Revisiting central concepts and aesthetic categories in literary criticism and theory, Randall Stevenson contributes a highly contemporary, ground-breaking vision of the literary act against the backdrop of the new structures of knowledge pertaining to the digital age and the post-humanist crisis.

Published: January 2022

This study was conducted to evaluate the chemical composition and biological activities of the leaf extracts of Syzygium myrtifolium Walp. (Myrtaceae). The results indicate that the leaf extracts of S. myrtifolium contain various classes of phytochemicals (alkaloids, anthraquinones, flavonoids, phenolics, saponins, tannins and triterpenoids) and possess antioxidant, antibacterial, antifungal and antiviral activities. Ethyl acetate, ethanol, methanol, and water extracts exhibited significantly higher (p < 0.05) oxygen radical absorbance capacity and ferric-reducing antioxidant power than the hexane and chloroform extracts. However, all extracts exhibited stronger inhibitory activity against four tested species of yeasts (minimal inhibitory concentration: 0.02–0.31 mg mL–1) than against six tested species of bacteria (minimal inhibitory concentration: 0.16–1.25 mg mL–1). The ethanolic extract offered the highest protection of Vero cells (viability > 70 %) from the cytopathic effect caused by the Chikungunya virus while the ethyl acetate extract showed significant replication inhibitory activity against the virus (p < 0.001) using the replicon-enhanced green fluorescent protein reporter system.
Current strategies in diagnostics and therapeutics against novel coronavirus disease (COVID-19)
Authors: ALOTAIBI FAISAL
Published: January 2022

The epidemic of COVID-19 spread quickly through China and engulfed all of the countries across the globe. Several advances have been made in understanding the novel coronavirus’s pathophysiology and in the development of newer diagnostics with pinpoint accuracy. Several newer therapeutic methods have either been accepted or are awaiting acceptance. In many countries, vaccination programs have been rolled out. Despite all these efforts, coronavirus still exists, though with lesser propensity. Multiple new forms of the novel coronavirus unexpectedly appeared in various areas of the world, undermining previously existing diagnosis and care protocols. This article highlights our understanding of the novel coronavirus’s symptoms in brief, pathogenesis, diagnostics, and therapeutic strategies to contain COVID-19. The clinical findings, including serological, radiological, and other advanced diagnostic strategies, contributed much to control the disease. To date, supportive interventions have been used in tandem with potent antiviral therapies such as remdesivir, lopinavir/ritonavir, or corticosteroids with a level of trust in the care of COVID-19 patients. However, in several areas of the world, vaccination initiatives took place; the vaccines’ safety and efficacy to control the outbreak is yet to be identified. This review concludes that improvement in therapies and diagnostics for COVID-19 must continually be explored as new variants constantly emerge.

The novelty of this work is the simultaneous analysis of sulbactam (SUL), ampicillin (AMP), and paracetamol (PARA) in human urine samples, using the environmentally benign RP-HPLC method. A C18 column was used in chromatographic separation using potassium dihydrogen phosphate (10 mmol L–1, pH 5)/ethanol (90 %, V/V) as the mobile phase; flow rate was 1.00 mL min–1. UV detection at 220 nm was used for quantification. The proposed method showed good linearity in the concentration ranges of 2.20–250.00 μg mL–1 for SUL, 2.50–250.00 μg mL–1 for PARA, and 14.50–250.00 μg mL–1 for AMP. Direct injection of urine samples with no prior extraction was performed. This method was found successful in moving towards greener studies of drugs’ urinary excretion, by decreasing hazardous solvent consumption and waste. Moreover, the method was applied to investigate the urinary excretion of the drugs and possible interaction between ampicillin and paracetamol.

Statins have shown anti-inflammatory pleiotropic effects in subjects with/at risk of cardiovascular disease. The aim of this study was to evaluate the inflammatory/immunomodulatory properties of rosuvastatin in subjects at low-to-moderate cardiovascular risk. Data was collected from patients’ records, physical examination and blood sampling. Subjects were assigned to rosuvastatin 20 mg per day. Rosuvastatin significantly decreased C-reactive protein (p = 0.045), and increased vascular endothelial growth factor (p = 0.004) and epidermal growth factor (p = 0.009). A multivariate analysis identified total cholesterol (p = 0.027) and vascular endothelial growth factor (p = 0.011) to be independently associated with rosuvastatin treatment. Given beneficial/harmful role of growth factors, vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF), in cardiovascular disease, one would suggest the need for routine monitoring of growth factor levels, especially in patients on long-term statin therapy.

Published: January 2022

Worldwide, the demand for raw materials and materials is constantly increasing, being proportional to the growth of the population. In this sense, the demand and production of solid fuels such as coal has grown steadily. At the level of the European Union, due to the restrictive coal extraction policy, production has steadily decreased and coal-producing countries have had to implement closure programs with strict deadlines. As mining networks shrink, there is an intensification of risk factors due to changes in the ventilation system. The paper presents the restructuring of a complex ventilation network.
Investigations on the Stability of the Right Slope in the Area of Anina Wastewater Treatment Plant

Published: January 2022

Often, excavations of natural slopes are necessary in the site area for the construction of civil or industrial objectives. The execution of such works requires special attention, from the design phase, regarding the stability of the slope in the initial state, but also after excavation and identification, if necessary, of technical solutions to increase the stability reserve, thus ensuring the security during the execution of works but also of future constructions. Such a situation was encountered in the case of Anina Wastewater Treatment Plant (WWTP), when, in the absence of proper investigations of the slope to be excavated, there was a landslide that interrupted the site activities, and which, to some extent, jeopardized the objectives already built. In this context, at the level of 2015, slope stabilization works were designed and executed, works that proved to be insufficient. In 2021, it was necessary to conduct a new stability study in order to analyze the possibilities of continuing the construction of the treatment plant. This paper presents the results obtained during this study, as well as a series of conclusions and interpretations, regarding the technical condition of the slope in different hypotheses.
Analysis of a Replaceable Cutting Tooth of Bucket Chain Excavator
Authors: Virág Zoltán , Szirbik Sándor
Published: January 2022

This paper briefly outlines the design of replaceable cutting teeth of bucket chain excavator, which are attached to a holder with a detachable joint. The description of the rock cutting process is very complex, so the investigation of the effect of lateral forces is complicated through cutting tests. We use accordingly numerical analysis to examine some segments of the cutting process. Our main objective is to present the finite element analysis of cutting teeth in which the linear increase of the lateral force is taken into consideration. The finite element analysis is a powerful technique, which is enabled to compute the stress and displacement distribution in cutting teeth. The simulation results have shown that the maximum stresses decrease if the lateral force increases. The geometry of the optimized cutting teeth will be safe under the given loading conditions.
