Integrating Commercial-off-the-Shelf Games into Language Classroom: PCaRD Experience of Two English Language Teachers
Authors: MUSAOĞLU AYDIN Seda , ÇAKIR Nur
Published: April 2022

This study aims to investigate two English language teachers’ perspectives on adopting a game-enhanced language learning intervention that was designed according to the PCaRD framework. For this purpose, a semi-structured interview protocol and researcher memos were utilized as data collection tools, and the data were subjected to thematic analysis. The results of the study indicated that the game-enhanced activities integrated into the curriculum were effective in promoting students’ foreign language learning and instrumental in helping students develop a more positive self-image about their foreign language abilities. Despite the time cost of preparing the activities bridging the commercial-off-the-shelf games into the existing curriculum and applying them in class and concerns about the negative connotation of video games, the PCaRD framework provides essential guidelines that teachers will find helpful for enhancing their students’ learning experiences and motivation for learning.

Authors: Vilcanqui-Alarcón Alexander , Pino-Vargas Edwin , Vargas-Bernuy Juana
Published: April 2022

Natural phenomena are difficult to control and predict, but risk management can prevent and reduce the risks of flooding due to the overflow of the Caplina River. This work seeks to determine the anthropic alterations and geomorphological characteristics of the Caplina river basin that generate a high risk of flooding in its trajectory. Existing information was used regarding the hydraulics of the Caplina river basin, carried out by the Tacna Special Project (PET), National Water Authority (ANA), Local Water Authority (ALA), National Meteorology and Hydrology Service (SENAMHI) and the Geological Mining Metallurgical Institute (INGEMMET). With field work, it was possible to establish thematic maps referring to areas of geomorphological alteration due to anthropic action and crops, which made it possible to determine areas prone to overflow and flooding at critical points. After the evaluation carried out in the study area, it was determined that the study area has a very high level of risk and vulnerability.

Computer-aided drug design (CADD) is a widely used technology using computational tools and resources for the storage, management, analysis and modeling of compounds. It relies on digital repositories for the study of designing compounds with physicochemical characteristics, predicting whether a given molecule will be combined with the target, and if so how strongly. Computer-based methods can help us to search new hits in drug discovery, screening many irrelevant compounds at the same time and study the structure-activity relationship of drug molecules.
ATLANTIS: An adaptive multi-arm phase II trial of maintenance targeted therapy after chemotherapy in advanced/metastatic urothelial cancer - Enzalutamide arm v1
Authors: J Jones Robert , Powles Thomas , Crabb Simon
Published: April 2022

Background: Metastatic urothelial cancer (MUC) is the eighth most common cause of cancer death in the UK. Chemotherapy is standard treatment for MUC. Although MUC is initially sensitive to chemotherapy, patients usually relapse within 6 months of completion. The outcome, once relapse has occurred, is very poor (median overall survival 8 months). Therefore, maintaining response to chemotherapy is an attractive goal, and a good environment for testing active single agents in MUC. ATLANTIS is a multi-arm, multi-stage signal searching trial. Patients will be allocated to treatment (vs observation or placebo where possible) based on biomarker expression. Design: ATLANTIS is a randomised phase II biomarker directed umbrella screening trial of maintenance therapy in biomarker defined subgroups of patients with advanced or metastatic urothelial cancer. The primary endpoint is progression-free survival. The protocol consists of a generic main section plus novel drug-specific appendices. The relevant novel drug-specific appendices will be amended when each specific subgroup trial completes or when a further novel drug subgroup is introduced. Central tissue screening for biomarker will occur prior to randomisation. Objectives: The trial will investigate whether maintenance targeted therapy after chemotherapy, with treatment selection based on biomarker expression, delays time to progression and overall survival for patients with MUC. Endpoints: Primary: To compare progression-free survival (PFS) of trial drug and placebo/observation. Different drugs will be tested in different biomarker defined subgroups in an adaptive design. PFS has been chosen as the primary end-point as it is largely objective (the majority of urothelial cancer patients will display progression in accordance with RECIST1.1 criteria) and clinically meaningful - progression after first line therapy represents the transition to the lethal stage of the disease and often the requirement for further cytotoxic therapy. Secondary: Overall survival, response rate, maximum percentage decrease in measurable disease, safety and tolerability. Exploratory: Progression free survival in subgroups defined by biomarkers other than those used for treatment allocation. Translational: Archival tissue, plasma and circulating tumor DNA will be stored and used for future research.

Authors:   Universiti Utara Malaysia, Abdullah Noor Aziah , Wan Mahmud Wan Amizah ,   Universiti Kebangsaan Malaysia, Sharipudin Mohamad-Noor Salehhuddin ,   Universiti Utara Malaysia, Yusuf Yusniza ,   Kementerian Dalam Negeri, Malaysia
Published: April 2022

The early history of the film industry is said to have begun in the United States. Nelayan and Laila Majnun were the first Malay films produced in Malaya, in 1932, produced by Motilal Chemical Company. This thought stems from the effect of the scenes depicted in the film. This study's objective is to explore if film has the power of being a threat to national security, and secondly, to identify the impact of audience dependence on film by applying the Media Dependency Theory. This study used an entirely qualitative method which consists of in-depth interviews with 19 informants consisting of policymakers, enforcement, legal practitioners, media industry players, and the audience. Analysis of documents related to legislation was also carried out. The study found that films can threaten national security if certain scenes were not censored. The effect of the audience's dependence on the film can influence and change their social life. This study is expected to contribute to the media industry to produce films that aim to maintain racial harmony and national peace. Keywords: Film, the power of films, media dependency theory, films censorship, Malaysia.

U radu se analizira slika Josipa Lalića Poljubac Perasta, nastala oko 1930. za Associazione Nazionale Dalmata u Rimu, prema njezinoj kopiji iz Muzeja grada Perasta u Crnoj Gori. Il bacio di Perasto sažima kompleksnu umjetnikovu biografiju, opus i ideološka uporišta, kao i tradiciju talijanskog historijskog slikarstva 19. stoljeća. Dok se u dijelu suvremene talijanske literature ova slika pokušava prikazati kao simbol povijesnog, ideološkog i kulturnog kontinuiteta, u ovom radu ona se tumači kao pseudopovijesni konstrukt utemeljen na političkoj agendi vremena u kojem je nastala.

Is digitalis currently useful for heart failure treatment?
Authors: Guadalajara-Boo José
Published: April 2022

Foxglove has been used for over 200 years to reduce water retention in its early days; Since the end of the 19th century, the treatment of heart failure has shown good clinical results. At the beginning of the 20th century, the treatment of heart failure began with good results and in the middle of the century scientific studies were carried out to determine the direct effects on the heart. 10 years later, clinical experience and technological advances demonstrated a really good efficacy that the digitalis effect had for the failing heart, with a defect: it is an old drug that appears obsolete for its current management in the presence of great new drugs that have proven useful in heart failure. From the last third of the 20th century, it was shown that the heart benefits from the combination are better than the drugs alone, so digitalis has a role that, in combination with the other drugs, significantly enhances the beneficial effects for the treatment of heart failure.
Dreams of Molecular Beams
Authors: Vallejo Kevin Daniel
Published: April 2022

Through the operation of a molecular beam epitaxy (MBE) machine, I worked on developing the homoepitaxy
of high quality InAs with a (111)A crystallographic orientation. By tuning substrate temperature, we obtained
a transition from a 2D island growth mode to step- ow growth. Optimized MBE parameters (substrate
temperature = 500 °C, growth rate = 0.12 ML/s and V/III ratio ⩾ 40) lead to growth of extremely smooth
InAs(111)A films, free from hillocks and other 3D surface imperfections. We see a correlation between InAs
surface smoothness and optical quality, as measured by photoluminescence spectroscopy. This work establishes
InAs(111)A as a platform for future research into other materials from the 6.1 Å family of semiconductors grown with a (111) orientation.

Continuing this work, we also have determined a reproducible set of growth conditions for the self-assembly
of tensile-strained In1-xGaxAs quantum dot nanostructures on InAs(111)A surfaces. During
molecular beam epitaxy, In1-xGaxAs islands form spontaneously on InAs(111)A when the Ga
content x ≥ 50 %. We analyze the structure and composition of InGaAs/InAs(111) samples using atomic force microscopy,
transmission electron microscopy, electron energy loss spectroscopy, and photoluminescence spectroscopy. We demonstrate
control over the size and areal density of the islands as a function of In1-xGaxAs coverage,
In1-xGaxAs composition, and substrate temperature.

Furthermore, we also present a study aimed to determining the growth conditions of In1-xGaxAs
self-assembled tensile-strained QDs on GaSb(111)A surfaces. From previous work we determined that a larger band gap
barrier was necessary to ensure the confinement of charge carriers in the InGaAs nanostructures. Through a series of
temperature, V/III ratio, and growth rate we determined the best parameters for GaSb(111) homoepitaxy. We then studied
the nucleation of optimal-morphology In1-xGaxAsQDs by locking the compositions at
In0.5Ga0.5As, studying the critical pause for group V element transition and V/III ratio prior
and post QD growth. Several photoluminescence techniques are employed to determine the light emission properties of these structures.

Finally, we did preliminary studies on how to achieve the dynamic lateral confinement of charge carriers in 2D and
3D using near-THz surface acoustic phonon pulses in polar semiconductors. Using the acousto-electrical effect, we measure
the degree to which surface acoustic waves (SAWs) confine electrons and holes limiting the number of recombination
processes. Applications for this technological development include the external modulation of lateral confinement size
in the SAWs and subsequent photon emission wavelength, as well as potential quantum logical gate design using acoustic pulses to drive electrons in a circuit.
A Wireless, Multi-Channel Printed Capacitive Strain Gauge System for Structural Health Monitoring
Authors: Ranganatha Kshama Lakshmi
Published: April 2022

Structural health monitoring of soft structural textiles plays a key role within the space industry to ensure the
safety and integrity of space habitats, parachutes, and decelerator systems. Strain monitoring could be an effective
means to evaluate structural integrity, but conventional monitoring systems are not suitable because they are intended
for large, rigid structures. To overcome the limitations of rigid sensors, we recently proposed using printed capacitive
strain gauges (CSGs) on flexible substrates to monitor the structural health of soft structure materials. Here, we present
a strategy and implementation of a wireless, multi-channel readout system for distributed monitoring of soft structural
textiles with printed CSGs. The system is comprised of localized sensor motes and a wireless Bluetooth hub. The sensor mote
employs a relaxation oscillator frontend to convert capacitance to frequency with a high dynamic range using only three
interface wires per mote. The mote’s high dynamic range ensures compatibility with various gauge designs and accommodates
significant process variation associated with printed gauges. Each hub enables users to read 8 channels of data wirelessly
at a sampling rate of 100Hz and can be scaled to higher channel counts through the use of additional hubs. The sensor motes
and wireless hub are miniaturized to accommodate flexible substrates, such as a Kevlar strap. The system is tested and exhibits excellent linearity and dynamic range.
Bioactivity Assessment of Veratrum californicum Alkaloids
Authors: Dirks Madison
Published: April 2022

The native Idaho plant Veratrum californicum is known to contain steroidal alkaloids that function as
inhibitors of hedgehog signaling, a pathway utilized for the growth and differentiation of cells as well as proper tissue
development. Veratrum californicum was originally noticed when pregnant ewes consumed the plant and later gave
birth to lambs with craniofacial mutations such as a cyclopean eyes. These malformations were caused by the plant’s steroidal
alkaloid cyclopamine blocking the hedgehog signaling pathway. This same pathway is used by more than 20 types of cancer for
multiplication of cells. Additional alkaloids have been found in Veratrum californicum, which are being studied
in order to identify additional hedgehog signaling inhibitors. There are at least seven compounds detected in extracts that are
completely uncharacterized, twelve with proposed identities, and the six known alkaloids veratrosine, cycloposine, veratramine,
cyclopamine, isorubijervine, and muldamine all within Veratrum californicum. In this thesis these molecules were
extracted together from the root and rhizome of the plant, and then separated into five fractions using high performance liquid
chromatography. Mass spectrometry analysis identified the presence of twenty five alkaloids (nine more than literature precedent),
and software processing of the data predicted the molecular formulas for each known, suspected, and unknown alkaloid. The bioactivity
of the raw extract and each fraction was assessed by comparison to 0.1 μM cyclopamine, and it was found that three fractions
suppressed hedgehog signaling to a greater extent, indicating the presence of bioactive constituents worthy of further
investigation. Five fractions were collected at 2.5 min intervals, beginning at 10.25 min from time of raw extract injection.
Fraction 1 was most potent at Hh signal inhibition, and was determined to contain veratrosine, cycloposine, and an isomer of
each, followed by fractions 2 and 4, which possessed elevated bioactivity, but to a lesser extent than fraction 1. Fraction
2 was predicted to be comprised of cycloposine, its isomer, an isomer of veratrosine, tetrahydrojervine, veratramine, dihydrojervine,
its isomer, etioline, and five unknown compounds. Fraction 4 was composed of cyclopamine, and suspected to contain isomers of
veratramine and cyclopamine, isorubijervine, and muldamine, as well as two unknown alkaloids.
OSMR Signaling Induces TAMP-Specific BBB Dysfunction Following Autoimmune-Mediated Neutrophil Recruitment
Authors: Wertz Travis Scott
Published: April 2022

Integrity of the brain microvessels that form the blood-brain barrier (BBB) is maintained through fine-tuned regulation of endothelial
tight junction proteins, chiefly represented by claudin 5 and the tight junction-associated MARVEL protein (TAMP) occludin. Under
proinflammatory conditions in autoimmune-mediated multiple sclerosis (MS), autoreactive effector T cells are activated in white matter
regions of the brain and spinal cord and release cytokines to recruit circulating neutrophils that, in turn, release neurotoxic
substances. Lack of tight junctions in peripheral blood vessels allows neutrophils to exit blood vessels unhindered, but BBB tight
junctions must first be downregulated before neutrophils can transmigrate into the brain. The resulting loss of BBB integrity initiates
a pathogenic feedback loop propagating the inflammatory injury. Understanding the established relationship between neutrophilia and BBB
dysfunction in neuroinflammation, I set out to better define the cellular contributions behind this pathology. Early on, I identified
increased circulating levels of the cytokine oncostatin M (OSM) concomitant with a pathogenic increase in OSM+ neutrophil counts during
the effector phase of experimental autoimmune encephalomyelitis (EAE), a mouse model of MS. Next, I found that BBB endothelial cells
selectively downregulate occludin, but not claudin 5, after stimulation with OSM. To dissect the mechanisms responsible, I identified
that fewer neutrophils are able to cross BBB endothelial monolayers lacking OSMRβ, the cognate OSM receptor. Finally, in OSMRβ-knockout
mice, I found a rescue in symptoms, BBB permeability to small molecules, and occludin expression during the effector phase of EAE.
Overall, this work identifies a novel role for OSM as an inflammatory cytokine released by neutrophils that specifically regulates
BBB TAMPs during autoimmune-mediated neuroinflammation.
The Influence of Positive School Orientation and Teacher Attachment on Adolescent Mental Health Outcomes
Authors: Holloway Stefanie Diann
Published: April 2022

Social and emotional learning (SEL) interventions can be delivered universally in schools to help equalize opportunities for diverse students
and improve their mental health, as well as other outcomes. However, it is not always known or fully understood which underlying mechanisms may
be at play that enable these interventions to achieve their effects –or how such mechanisms may develop over time, within an SEL intervention.
The primary purpose of this study was to determine how one such intervention, Positive Action, was able to improve adolescent
students’ mental health outcomes, by testing the potential mediational influences of students’ levels of positive school orientation and teacher
attachment upon different groups’ outcomes of self-reported depressive and anxiety symptoms. Findings revealed that both constructs played a
significant role in students’ outcomes of depressive and anxiety symptoms at the end of their participation in the program.
Video Communication
Authors: Belt Eric S.
Published: April 2022

Educators and students are using synchronous and asynchronous video communication technologies in unprecedented ways given the ongoing
global pandemic. Despite continued educational research on video communication technology, less is known about the social implications
of these forms of communication. Online learning has faced challenges (e.g., learner isolation, technological competency, and time
management) since its inception; these challenges have been exacerbated in the rapid transition to emergency remote teaching. Given
problems like these, additional research is needed to better understand how video communication technology can be used to improve
communication and interaction in online learning. The following dissertation presents a series of qualitative studies aimed at exploring
the communicative aspects of community and connectedness with video communication technology in the context of online teaching and
learning. Chapter one presents an introduction to this research space and a statement of the problem that exists in text-based
communication and how video communication may address some shortcomings of text-based communication online. Chapter two presents
a synthesis of the literature on more recent (i.e., 2010-2020) uses of video as a teaching tool in online and blended courses; the
themes that emerged from this study help identify common interdisciplinary uses of video communication technology and help identify
gaps in the literature. The gaps identified led to two different studies. Chapter three presents an exploratory study of faculty
perceptions of synchronous video-based communication technology in online courses relative to classroom community building and
development; the themes that emerged from this study help highlight the potential of visual communication in community building and
identify a need for pedagogical tact in synchronous sessions. Still, this study suggests that synchronous sessions in traditionally
asynchronous online courses are not the only ways in which community may develop. Chapter four presents a phenomenological study of
doctoral students’ lived experiences of the teacher-student relationship with online teachers; the thematization of aspects in this
analysis suggests that prolonged communication and interaction between teacher and student are not the only ways that students may
experience a sense of connectedness to online instructors. The two studies that comprise chapters three and four, respectively, inform
an understanding of the communicative aspects of community and connectedness in different ways and from different perspectives that
illuminate the qualitative consequences of video communication in online teaching and learning. In chapter five, a summary and synthesis
of these three studies is presented along with implications for practice and areas in need of further research.
Controls on the Frequency Content of Near-Source Infrasound at an Open-Vent Volcano (Villarrica, Chile)
Authors: Rosenblatt Bryan Blake
Published: April 2022

The acoustic signals from open-vent volcanoes can contain specific information related to that volcano’s eruption dynamics and
future activity. Thus, studying a specific volcano’s acoustics may provide critical warning mechanisms, signaling impending
eruptions. Villarrica volcano, located in southern Chile, has an active lava lake that produces continuous infrasound with
spectral peaks near 1 Hz and excursions of +/- ~0.2 Hz. The infrasound’s frequency content reveals key volcanic properties
such as eruption style and crater shape. Leading up to Villarrica’s most recent paroxysm in 2015, infrasound spectral changes
coincided with and indicated a rise in Villarrica’s lava lake level. As such, quantifying and understanding the regular
fluctuation in recorded infrasonic frequencies, from Villarrica and other open-vent volcanoes, is imperative. A week-long
period of crater rim infrasound observations associated with stable, open-vent activity, revealed two independent source
processes: spatter bursting events and lava lake-induced tremor oscillations (broadband discrete signals and ~1 Hz tremor
respectively). Comparison of these acoustic signals with results from a 3-D finite-difference time-domain wave propagation
model (InfraFDTD) shows that sound speed and source spectrum variability can both influence Villarrica’s spectrum. Yet, sound
speed variations in the crater--whether diurnal or volcanic in origin--cannot explain the full extent of the observed frequency
excursions. Instead, source spectrum variability is primarily responsible for the frequency excursions. This work highlights the
utility of data collected from a dense distribution of twenty infrasound sensors operating at the summit and validates the effectiveness of the InfraFDTD modeling approach.
Occupational Safety and Health Coordinators – Puzzle-piece Caretakers or Necessary Evils
Authors: Ajslev Jeppe Zielinski Nguyen , Møller Jeppe Lykke , Nimb Ika Elisabeth Ejstrup
Published: April 2022

The construction industry continues to be high-risk in terms of occupational safety and health (OSH) issues. A pivotal instrument in preventing these risks at both European and Danish levels is the OSH coordinator. In spite of the important role of the coordinator, little research on their roles and functions exist, and critics have pointed out that OSH professionals in general may only confer limited impact on preventive OSH work. This study argues that professional identities and struggles to maintain preferred, as well as rejecting unwanted identities are highly important to understand OSH coordinators’ practices. The study investigates OSH coordinators professional identities and their implications for practice through analysis of interviews with 12 experienced OSH coordinators in the Danish construction industry. The study reveals how struggles for maintaining a positive self-image and social recognition may explain why coordinators struggle to prioritize preventing OSH risks over legitimization and social practices.

O ataque a fontes de água como crime de guerra: análise no âmbito do Tribunal Penal Internacional
Authors: Silva José Irivaldo Alves Oliveira , Caldas Beatriz Nogueira , Magalhães Sara Alves
Published: April 2022

O artigo proposto traz uma análise da água como um direito humano, sob a perspectiva do direito penal internacional, considerando a existência de casos em que ataques sistemáticos a fontes de água são utilizados como uma estratégia de guerra em conflitos armados. Uma vez que aquíferos são contaminados, a população daquela região fica vulnerável, causando um grande problema humanitário. Assim, a pesquisa procura avaliar se ataques a fontes de água durante conflitos armados podem ser considerados um crime de guerra, dentro dos parâmetros estabelecidos pelo Estatuto de Roma. Para isso, é feito um estudo do caso de Darfur, no Sudão, julgado pelo Tribunal Penal Internacional (TPI), onde há evidências de que tanques de água foram propositalmente contaminados pelo governo, por ordem do ex-presidente Omar Al Bashir, para combater ataques de tropas rebeldes. Também é feito um estudo sobre o Estatuto de Roma, e sua definição de crimes de guerra, como forma de verificar se ataques voltados ao meio ambiente estão dentro do escopo penal do Estatuto. O método utilizado é o dedutivo aplicado a uma pesquisa qualitativa, feita por meio de um levantamento bibliográfico, com análise de artigos científicos e livros, além de fontes documentais. A pesquisa baseia-se em um estudo de caso concreto, referente à demanda da Procuradoria do TPI contra Omar Al Bashir. Apesar do TPI ser competente para julgar esse tipo de crime, isso não ocorre de forma eficaz.

TÜRK AKADEMİSYENLERİN TÜRKİYE'DE YÜKSEKÖĞRETİMDE MEDYA OKURYAZARLIĞI DEĞERLENDİRMESİNE İLİŞKİN ALGILARI
Authors: ALTAŞ Betül , ÜNAL Sevda
Published: April 2022

This descriptive study investigates Turkish academicians' perceptions of the media literacy outcomes, assessment, and challenges of media literacy education, and their recommendations to overcome these challenges in higher education. Data were collected from 41 Turkish academicians working at Turkish universities from seven geographic regions. Data were collected via the "Media Literacy Assessment Questionnaire" which was developed by Schilder (2014). Participants were academicians with subject-area specialisation in English Language Teaching, Computer Education and Instructional Technology in the education faculty, and academicians with subject-area specialisation in the departments of communication faculty as these academicians were interested in media and technology and media literacy education. Results of the study reveal that formative assessment was a prominent assessment method; however, most assessment methods that the academicians used were also identified as time-consuming or complex to develop. Results also show that academicians were unsure about how to interpret students' responses to assess their media literacy and identified teachers' insufficient training as a challenge in assessing outcomes. Based on the data results obtained from this study, specifying learning outcomes beforehand shouldn't be accomplished by the force of administration, but should be determined by the consensus among all parties in the field. Results also reveal that critical literacy and pedagogy should be taken into account in media literacy education so that learners can become critically autonomous citizens in this globalised world.

A group of fish was fed with 0.25; 0.50; 1.0; 2.0% MBE and compared to control group (without MBE) for 75 days observation. At the end of feeding trial, growth parameters, hematological profile such as red blood cells (RBC), white blood cells (WBC), Hemoglobin (Hb), Hematocrit (Htc), differential leukocyte, blood plasma biochemistry (glucose, total albumin, cholesterol, and triglyceride), the hepatosomatic (HSI) and intestinal somatic index (ISI) were measured. Survival of all fish was also counted every two weeks. Supplementation MBE above 0.25% resulted significantly higher final biomass weight (FBW), body weight gain (BWG), daily weight gain (DWG), and average weekly gain (AWG). Meanwhile, fish group fed dietary MBE above 1.0% had significantly higher specific growth rate (SGR) (3.32±0.15) than other groups. Fish fed 1.0% of MBE also showed better value of feed conversion ratio (FCR) (1.13±0.03), Hb, and HSI compared to others group. Survival, neutrophil, monocyte, and ISI of all groups was not affected by any concentration of MBE supplementation. Dietary MBE above 0.5% enhanced RBC, WBC, Hematocrit, platelet (PLT), lymphocyte, blood plasma biochemistry such as glucose, total albumin, and triglyceride. Cholesterol of fish fed MBE in the diet showed incrementally enhanced. Present finding suggested that 1.0% MBE in the diet of Clarias gariepinus is recommended to enhance growth, survival, and blood profiles

This study empirically explores factors determining the production of fish aquaculture in the South Aceh District, Indonesia. The study selected 150 out 1,893 aquaculture fish farmers within 18 sub-districts in the regency as the study’s respondents using a multi-stage sampling technique. Primary data collected through questionnaires’ distribution were analyzed employing a multiple regression model. The research documented empirical evidence that fish pond area, number of fish farmers, and capital significantly and positively influenced the production of fish aquaculture in the South Aceh Regency. Meanwhile, the number of fish seeds had an insignificant impact on the production of fish aquaculture. These empirical results suggested that in improving aquaculture fish production, fish farmers have to possess an adequate amount of capital, pond area, and the number of workers. Soft loan assistance sourced either from the government or banking institutions, conversion of idle and abandoned lands into fish ponds, and various fisheries capacity building programs is among the strategic steps that require to be taken to extend aquaculture production.

Maggot (Black soldier fly larvae) as an alternative source of protein on feed can increase fish productivity. The research aims to study maggot flour as an alternative source of protein in feed on the growth, structure of the intestine organs and skeletal muscles of Mutiara catfish (Clarias gariepinus Burchell, 1822). The research used 144 Mutiara catfish that were kept for 21 days. The research used a completely randomized design consisting of 4 groups, namely 0% maggot in feed (Control), 25% maggot in feed (P1), 50% maggot in feed (P2), 75% maggot in feed (P3). The parameters consist of the growth, the structure of intestine and skeletal muscle of Mutiara catfish. Growth observations consist of measurements of the absolute length and weight of the fish. Intestine observations consisted of length and weight, as well as tissue structure consisting of villi height, crypt depth, villi / crypt ratio and villi area area. Skeletal muscle observations consist of muscle weight and tissue structure consisting of the diameter and area of muscle fibers. Data analysis was performed with one-way anova, followed by the Duncan Test. The results showed that 75% maggot feed gave significant results on absolute weight, structure of intestine and muscle organs compared to other treatments (P <0.05). The absolute length did not provide a significant difference between treatments (P> 0.05). The conclusion shows that 75% maggot feed can be used as an alternative source of feed protein because it can increase the growth, structure of the intestine organs and skeletal muscles of the Mutiara catfish.

The aim of this study was to determine the PCB levels in the Atlantic Mackerel (Scomber scrombus) sourced from cold storage points in Benin City, Nigeria by GC analysis and its suitability for human consumption. The PCB concentrations (mg/kg) in S. scombrus ranged from 0.0183 for PCB 114 to 0.5542 for PCB 126 with a recorded total of 0.991 while the mean concentrations (mg/kg) of PCBs in S. scombrus by cold storage point ranged from 0.0111 for PCB 114 to 0.684 for PCB 126 both at the New Benin points, with no observed significant difference (P>0.05) in the mean concentrations of PCBs 126, 156 and 180 in fish between these points. The mean concentration (mg/kg) of PCBs in S. scombrus by month peaked in June with a value of 0.615 for PCB 126. However, there was no observed significant difference (P>0.05) in the mean concentrations of PCBs 114, 118, 138, 153, 156 and 180 in fish specimens between months. Essentially, data from the study revealed that the experimental fish species are suitable to eat by the consuming public as there was no glaring indication of immediate health hazard.

In the current study nanocellulose was isolated from walnut shell using mechanical and chemical methods. This study highlights the particle size, morphology and these methods’ efficiency in nano structure extraction. The difference between morphology and size of the particles (of the both extracted methods) were investigated by field emission scanning electron microscopy (FESEM). Walnut shell is an agro-waste material with source of lignin and cellulose. Ball mill-ing with different times, in the presence and absence of additive and acid hydrolysis were used as mechanical and chemical methods, respectively. The result showed mechanical method is unable to extract nanoparticle and just reshape the walnut shell. Milling time were also found important in morphology of fiber extracted. FE-SEM images represented that structure mean diameter of using ball mill was 1± 5 μm while hydrolysis acid method extract nano particle with mean diameter of 40± 20 nm.
