Pyrostegia venusta is known as an ornamental plant with its source of antioxidants, cytotoxic, anti-inflammatory, and anti-HIV compounds. Ephypitic molds are potentially co-existed on the surface of this flower since it contains essential nutrients which support their growth. On the other hand, molds produce several enzymes that might involve flower growth. The presence of ephypitic molds on this flower provides information about its ability to produce amylase. This study successfully isolated molds from August flower (P. venusta) originating from Taman Nasional Bedugul, Bali, Indonesia. The study aimed to isolate potential amylase producer strains and optimize the enzyme production using Solid-State Fermentation (SSF) method. Ten mold isolates belonging to Universitas Negeri Jakarta Culture Collection (UNJCC) were selected according to their amylolytic index (IA) values, morphological identification, and colony count number. Selected strains were optimized for its growth to produce amylase using the SSF method under different temperatures (30, 40, 50°C) and pH (6, 7, 8) with a wheat brain fermentation medium. Results showed that UNJCC F100 (6.53 × 108 CFU/ml) and UNJCC F106 (9.83 x 108 CFU/ml) are the two isolates with the highest IA values of 1.34 ± 0.1 and 1.08 ± 0.12 among all isolates. Based on molecular identification using ITS region, UNJCC F100 and UNJCC F106 were identified as A. subflavus (97% homology) and A. fumigatus (99.52% homology), respectively. This study exhibited that both isolate UNJCC F100 and isolate UNJCC F106 have optimal amylase production conditions at 30°C and pH 6. The enzyme produced was 19.99 U/ml at 30°C and 34.33 U/ml at pH 6 for isolate UNJCC F100, and for isolate UNJCC F106 is 28.55±3.80 U/ml. The two isolates are potentially used for amylase production, referring to the specific environmental condition. However, to generate a higher amount with amylase activity, other external variables such as medium used, inoculum concentration, and fermentation method are important to consider further for a larger application.

No muestran cambios los indicadores cuantitativos: producción agrícola, ingresos económicos o consumo de kilocalorías. Conocer los cambios cualitativos o cuantitativos, positivos o negativos, permitirá recuperar aprendizajes para la gestión integral de sistemas de vida.
Bahasa Hukum Qanun Jinayat Aceh: Teks Lama untuk Konteks Baru
Authors: Abubakar Ali , Din Mohd
Published: August 2022

Abstract: This paper begins with the problem of differences in public perception and law enforcement in enforcing the Qanun Jinayat. The main question to be answered is how to understand the legal language of the Qanun in the concept of the relationship between the text and the legal context? Several legal terms and concepts in the Qanun were selected for analysis. The results of the study indicate that the terms and concepts in the Qanun which are different from the language of the law in Indonesia show the characteristics of the law itself. The choice of the legal language of the Qanun reinforces that the law must change according to changing contexts; namely modern Acehnese society. However, the text of the Qanun itself, due to changes in context, cannot be separated from the possibility of changes/adjustments.Abstrak: Tulisan ini berawal dari permasalahan perbedaan persepsi masyarakat dan aparatur penegakan hukum dalam penegakan Qanun Jinayat. Pertanyaan utama yang ingin dijawab adalah bagaimana memahami bahasa hukum Qanun dalam konsep hubungan antara teks dan konteks hukum? Beberapa istilah hukum dan konsep dalam Qanun dipilih sebagai bahan analisis. Hasil penelitian menunjukkan bahwa istilah-istilah dan konsep-konsep dalam Qanun yang berbeda dengan bahasa perundang-undangan di Indonesia menunjukkan ciri dari hukum itu sendiri. Pilihan bahasa hukum Qanun menguatkan bahwa hukum harus berubah sesuai dengan perubahan konteks; yaitu masyarakat Aceh modern. Namun demikian, teks Qanun itu sendiri, karena perubahan konteks tidak terlepas dari kemungkinan perubahan/penyesuaian.

Dari Pelaku ke Korban Penyelundupan Pekerja Migran Sukarela: Pilihan Hukum Internasional atau Hukun Indonesia
Authors: Sirait Yohanes Hermanto , Narwastuty Dian
Published: August 2022

Abstract: Migrant smuggling and human trafficking are two actions that are often equated. Though both are distinct in terms of profit and purpose. Migrant smuggling can occur because of consensus between migrants and smugglers. In contrast to the perpetrators, international law encourages the non-criminalization policy to migrant. However, the practice of countries including Indonesia still provides chance for criminalization of migrants. This study aims to examine the impact of migrants volunteering to be smuggled in as victims. Furthermore, the potential for migrants to be punished for violating the rules for entering without a permit into a country is also studied. This research was conducted doctrinally using primary, secondary, and tertiary legal materials. The results showed that the volunteering of migrants to be smuggled should not their status to become perpetrators in perspective of international law. It means that migrants should be punished for being smuggled. However, national laws, including those regulated in Indonesia, still allow migrants to be punished for violating the rules regarding entry permits such as the use of fake documents. This shows the lack of consistency in national laws to adopt non-criminalization policies towards migrants.Abstrak: Penyelundupan migran dan perdagangan orang adalah dua tindakan yang kerap dipersamakan. Padahal keduanya berbeda dari sisi keuntungan dan tujuan. Penyelundupan migran dapat terjadi karena adanya konsensus antara migran dengan pelaku penyelundupan. Berbeda dengan pelaku, hukum internasional mendorong kebijakan non-kriminalisasi terhadap migran. Namun sayangnya, praktik negara termasuk Indonesia masih memberikan ruang untuk kriminalisasi terhadap migran. Penelitian ini bertujuan mengkaji dampak kesukarelaan migran untuk diselundupkan sebagai korban. Lebih lanjut, dikaji juga potensi migran dipidana karena melanggar aturan masuk tanpa izin ke suatu negara. Penilitian ini dilakukan secara doktrinal menggunakan bahan hukum primer, bahan hukum sekunder dan bahan hukum tersier. Hasil penelitian menunjukan bahwa kesukarelaan migran untuk diselundupkan tidak membuat status dan kedudukannya berubah menjadi pelaku. Konsekuensinya, migran tetap tidak boleh dipidana dengan alasan apapun. Namun hukum nasional termasuk yang diatur di Indonesia masih memungkinkan migran dipidana karena melanggar aturan terkait izin masuk seperti penggunaan dokumen palsu. Hal ini menunjukan kurang konsistennya hukum nasional mengadopsi kebijakan non-kriminalisasi terhadap migran.

Authors: Sakthivel M , Sahaya Leon J.Prakash
Published: August 2022

Aquaculture is identified as the viable alternative source, for increasing fish production to meet out ever growing demand for fish consumption. Due to their high nutritive value, toxic-free, environment friendly and high productivity Azolla and Spirulina were considered as promising feed. The knowledge of hematological and growth characteristics is an important tool that can be used as a sensitive and effective index to monitor pathological and physiological changes in fish. Consumption of Azolla and Spirulina by fish can have direct or indirect effects on human health. In the present study, a survey was conducted in humans to analyze the effect of Azolla, Spirulina through fish tilapia consumption and also to analyze the hematological and growth changes the fish Oreochromis mossambicus were exposed to different concentrations of spirulina and Azolla with commercial fish feed. Fishes were selected for the weight of (21gram) and length of (11cm) for the present experiment. In the control group, 6 fishes were exposed to 20 grams of commercial fish feed. In the first group T1 (experiment 1) 6 fishes were exposed to 8 grams of Azolla with 12 grams of commercial fish feed, in the second group T2 (experiment 2) 6 fishes were exposed 8 grams of Spirulina with 12 gram of commercial fish feed and in the third group T3 (experiment3) 6 fishes were exposed 4 grams of Azolla and 4 grams of Spirulina with 12 gram of commercial fish feed for 60 days. In the present investigation, growth level was increased when fish Oreochromis mossambicus was exposed to different concentrations of Spirulina and Azolla with commercial fish feed, and also significant differences were observed in the blood parameters like white blood cells (WBC), Red blood cells (RBC), Hemoglobin (HB), MCV and MCH. A questionnaire-based dietary survey of tilapia consumers were collected in detail through face-to-face interviews at fish shops located nearby KRP Dam, Krishnagiri district. Statistical data were analyzed using SPSS software and all tests were considered significant at p<0:05. Main objective of the present study is to analyze the growth and hematological effect of Azolla, Spirulina in fish tilapia and also to identify the fish (Oreochromis mossambicus) consuming people through questionnaire-based survey. It is concluded that more people consumed fish tilapia as a common food and fish fed with azola and spirulina showed rich nutritive value. So, the present study recommended that, if the fish tilapia is fed with azolla and spirulina, this may increase the nutritive states of human populations via fish Tilapia.
Decentring Anthropocentric Narcissism: The Novum and the EcoGothic in Cixin Liu’s The Three-Body Problem and Ball Lightning
Authors: Dories Jeff
Published: August 2022

Abstract: This article examines Cixin Liu’s The Three-Body Problem and Ball Lightning using the framework of Liu’s essay “Beyond Narcissism: What Science Fiction Can Offer Literature,” as well as the idea of the ecogothic, as outlined by William Hughes, Andrew Smith, David Del Principe, and Emily Carr. Liu discusses the idea that literature primarily focuses on human relationships. He then explains that the universe is vast, and in the 13.2 billion years of history, humans have only been present for a small percentage of that time. Because of this, he calls for literature to experiment with challenging anthropocentric thought. This article focuses on how Liu uses ecological horror, feelings of dislocation, disorientation, fragmentation, and the uncanny to challenge anthropocentric ideology. It relies on close reading and an examination of intertextuality, especially focusing on Rachel Carson’s Silent Spring and Peter Singer’s Animal Liberation.

Functional screening for salt-tolerant bacteria in industiral park sewage treatment plant
Authors: Li Zaixing , Zhang Wanyu
Published: August 2022

The effluent of pharmaceutical wastewater had the characteristics of
high salt and high COD. After discharge, it had a certain impact on the
biological treatment of the sewage plant in the industrial park, which
makes the effluent difficult to meet the standard. Therefore, it was
necessary to screen out microorganisms with salt tolerance and the
ability to reduce organic matter to improve the biochemical treatment
effect of the sewage treatment plant. Therefore, the purpose of this
study was to isolate and screen salt tolerant microorganisms to improve
the biochemical treatment efficiency of sewage plant. Two salt tolerant
strains T3 and T4 were screened from the sludge of the secondary
sedimentation tank of an industry park sewage plant. Through
morphological observation and 16S rRNA sequence analysis, it was
identified that T3 strain was Mangrovibacter yixingensis and T4
strain was Thauera selenium. The effects of process conditions
such as salinity and pH on the degradation of COD in actual high-salt
wastewater were investigated by single factor experiment, and the
optimum combination of conditions was determined by orthogonal
experiment. T3 strain had high COD degradation efficiency at the best
condition (salinity 2%, inital pH 6 and inoculation ratio 5%). The
best condition on organic matter removal of T4 was salinity 1%, initial
pH 6 and inoculation ratio 10%. Therefore, salt-tolerant bacteria had a
certain application prospect on degradation of organic matter in
high-salt wastewater.
Study on heat exchangers and industrial absorption column for drying polyethylene terephthalate
Authors: Silva Felipe , Bastos Izabella
Published: August 2022

This study proposes the use of mass balance and the method of McCabe-Thiele in the absorption column for the removal of drying air humidity with ethylene glycol and energy balances in heat exchangers for the determination of the optimum operating conditions of a factory to produce recycled polyester fibers from polyethylene terephthalate (PET) flakes. The evaluation of these machines involved the combination of variables such as temperature, flow rate, specific heat, and operational efficiency to guarantee the correct adjustment of the physicochemical properties of the fluids and materials of the process. The efficiency of the absorption column was determined at 25%, and a diagram correlating ethylene glycol humidity, the dew point of the drying air, and the efficiency of humidity removal from the PET flake dryer were constructed to define what is the most appropriate configuration for operation. By the graph curves, it was found that the humidity of ethylene glycol for absorption should be inferior to 1% (w/w) to guarantee a dew point < -27?C at 175?C of the drying air introduced in the dryer, which would finally promote a removal with efficiency superior to 91% of the PET flake humidity for values < 0.005% (w/w).

Objectives: The primary objective was to determine the responsiveness of the Dutch version of the 13-item Tampa Scale for Kinesiophobia for cardiac patients (TSK-NL Heart). The secondary objective was to assess changes in kinesiophobia during cardiac rehabilitation.Methods: Kinesiophobia was measured pre- and post-cardiac rehabilitation using the TSK-NL Heart questionnaire in 109 cardiac patients (61 years; 76% men). The effect size of kinesiophobia score changes was calculated for the full population. A measure that is responsive to change should produce higher effects sizes in patients in whom kinesiophobia improves. Therefore, effect sizes were also calculated for patients who did or did not improve on selected external measures. For this step, the Cardiac Anxiety Questionnaire (CAQ) and the Hospital Anxiety and Depression Scale (HADS) were completed as external measures in a subsample of 58 patients.Results: The effect size of the TSK-NL Heart for the full study population was small (0.29). In line with the study hypothesis the effect size was higher (moderate) for patients with improved CAQ (0.52) and HADS scores (0.54). Prevalence of high kinesiophobia levels decreased from 40% pre-cardiac rehabilitation to 26% post-cardiac rehabilitation (p = 0.004).Conclusion: The TSK-NL Heart has moderate responsiveness and can be used to measure changes in kinesiophobia. Improvements in kinesiophobia were observed during cardiac rehabilitation. Nevertheless, high levels of kinesiophobia were still highly prevalent post-cardiac rehabilitation.
LAY ABSTRACTFear of movement (kinesiophobia) is common in patients referred for cardiac rehabilitation. Before interventions can be designed to target kinesiophobia, the impact of current cardiac rehabilitation programmes on kinesiophobia should be studied. Kinesiophobia is measured with the Tampa Scale for kinesiophobia (TSK-Heart). In order to measure the effect of cardiac rehabilitation on kinesiophobia, the TSK-Heart should be able to detect changes in the level of kinesiophobia (responsiveness). This study determined the responsiveness of the TSK-Heart and assessed changes in the level of kinesiophobia during cardiac rehabilitation, and shows that the TSK-Heart has moderate responsiveness. In addition, it was found that the prevalence of high levels of kinesiophobia, decreased from 40% before cardiac rehabilitation to 26% after cardiac rehabilitation.

The study is qualitative in nature and is based on field studies in grade 2 (aged eight), along with focus groups involving teachers who work with and around pupils. Two research questions have served as a guideline for the study:  1. What characterises teachers’ experiences and didactic usage of digital technology when teaching children (to read and write), and 2. How is digital technology used to promote different dimensions of reading and writing processes? The results show that teachers use digital technology to differentiate teaching in various ways; by illustrating, motivating, individualising and making the didactic content accessible, for example. Digital technology is used when teaching children to read and write in order to promote both individual skills and activities promoting communication and creating meaning. Digital technology appears to provide opportunities for teachers to offer particular support within the classroom framework and offer pupils tasks at custom levels, thereby helping to provide a more inclusive didactic space. This study highlights teachers’ somewhat ambivalent approach and balancing of different didactic choices in relation to digital technology.

Ceremonial Transformation: The Significance of Renaming Memorial Hall after Sarah Baartman at the University of Cape Town
Authors: Mlambo Yonela , Xulu-Gama Nomkhosi
Published: August 2022

At the end of 2018, the University of Cape Town renamed its prominent Memorial Hall after Sarah Baartman, which signalled a significant contribution towards transformation endeavours for the institution. This article is a critical literature review of institutional transformation and practice at UCT which examines the significance of renaming the Memorial Hall. Relying on already published work, it explores student and staff experiences to argue that renaming buildings without changing the lived experiences of those who occupy such buildings is not enough. Therefore, the article concludes that attempts at transformation need to stop being solely ceremonial and recommends that UCT improve its transformation efforts. A process that will hinge on the interrogation of the non-traditional experiences of those who now occupy the buildings during and after the renaming processes, especially for buildings as significant as the Memorial Hall.
Expectations versus Realities: Insights into the Transition Experiences of International Students at Two Universities in Nigeria
Authors: Agbaje Olaide , Sehoole Chika
Published: August 2022

Attracting, recruiting and retaining international students should be balanced with the need to provide support for the smooth transition of these students into their host countries and institutions. One way to achieve this transition is by bridging the gap between international students’ expectations and actual realities. Hence, this article examines the impact that the expectations and the realities of studying abroad have on the overall transition experiences of international students in Nigeria. The study adopted a mixed method and employed Schlossberg’s theory of transition to further understand the phenomenon of transition with regard to international students. Paper questionnaires were collected from 64 international students at two universities in Nigeria, while a subset of 20 (10 from each university) was further interviewed. The findings indicate that unmet expectations contributed largely to difficult transition experiences for the international students in Nigeria.
Understanding the Experiences of Mauritian Students at Institutions of Higher Education Overseas
Authors: Ammigan Ravichandran
Published: August 2022

Each year, a significant number of students from the Indian Ocean island of Mauritius seek higher education opportunities abroad. Yet, limited research exists on these students’ expectations, preferences, and experiences in their academic and non-academic university settings overseas. This quantitative study investigates the experiences of Mauritian degree-seeking students at universities in Australia and the United Kingdom, which have been two of their most preferred destination countries for Mauritian international students over the years. It specifically examines associations between overall university satisfaction and various aspects of the student experience in the arrival, learning, living, and support services environment. Analyses from this research reveal that a number of satisfaction variables were important to students, namely the opportunity to make friends on campus, the availability of social activities and facilities, internet access and IT support, and chaplaincy or multi-faith provision. Implications for international educators, university administrators, and guidance counselors are discussed.

Concepções de professores de alunos surdos sobre inclusão e educação bilíngue
Authors: Pinto Milena Maria , Santos Lara Ferreira dos
Published: August 2022

O sistema educacional inclusivo no Brasil apresenta diversos desafios, sendo os principais relacionados à organização social – desde valores e concepções dominantes aos meios mais adequados para uma educação de qualidade para todos. Considerando a surdez como diferença linguística, este trabalho tem como objetivo compreender as concepções sobre educação bilíngue e inclusão dos professores de alunos surdos na educação infantil, relacionando práticas pedagógicas, a Língua Brasileira de Sinais e o desenvolvimento. Trata-se de uma pesquisa de caráter qualitativo, tendo como instrumento de coleta de dados um questionário online. Participaram da pesquisa 15 professores ouvintes que atuam ou atuaram em salas de educação infantil com a presença de um ou mais alunos surdos em escolas da rede pública do Estado de São Paulo no período de 2016 a 2020. As análises são fundamentadas na abordagem histórico-cultural, a partir de trechos das respostas, proporcionando discussões sobre a realidade educacional de alunos surdos quanto ao modelo educacional, considerando a proposta inclusiva e o modelo bilíngue. Os resultados indicam que a satisfação escolar ainda é pautada apenas na inserção de surdos em escolas, mesmo que essas não promovam transformações efetivas no ensino e que não tenham metodologias e práticas pautadas na Língua Brasileira de Sinais. Assim, há falta de conhecimento da Língua Brasileira de Sinais como a primeira língua dos alunos surdos e como a língua de instrução na educação e centralidade no desenvolvimento.

The COVID-19 pandemic has induced a series of credit risk problems for most commercial banks in the GCC region. Thus, the current paper aims to examine the impact of both credit risk and bank-specific drivers on commercial banks’ financial performance in the UAE from the period 2017 - 2021. The study used NPLs, LLP, and DR as credit risk indicators while CER, LR, and NPLs were used as bank-specific drivers and ROA as financial performance measures. The Random Effect model was used for data analysis. The findings revealed that NPLs and LLP had a negative and significant effect on ROA while CER, LR, and, NPLs were found to have a negative and significant relationship with ROA. This paper implies that banks need remain prudent in their credit risk management and adopt the best strategies to manage and control bank-specific drivers to improve their performance
