Authors: Rakhi RF , Shahariar MA , Alam MS
Published: July 2023

The fastest-growing aquaculture industry plays a crucial role in fulfilling the increased demand for animal protein. However, the outcomes of the sectors are greatly hindered by unexpected disease prevalence, environmental degradation, organic and inorganic pollutants in aquaculture operations, and ineffective feed exploitation to achieve the global food security goal. There has been little research on the impact of nanotechnology on fish nutrition and improved health, despite the fact that the application of nanotechnology in food production systems is being studied globally. In this respect, scientists are generating and inventing new potential ideas and technology to cope with these challenges in aquaculture. Among them, the use of nanoparticles (NPs) has grown in popularity due to their numerous attractive and distinctive features and also tremendous potential to improve aquaculture production. New ideas regarding the application of NPs in fish medicine, drug delivery techniques through NPs, diet formulation to enhance feed efficacy, and as an antiviral or antimicrobial agent to control disease prevalence in aquaculture systems to augment overall production have been discussed. Commercially cultured fish species, including shrimp, Thai koi, Common carp, Grass carp, and Tilapia, have been shown to respond favorably to a variety of nanoparticles (eg. silver, gold, iron, copper, zinc, selenium, and chitosan). Thus nanoparticles researched-based information in finfish and shellfish aquaculture have short-term or long-term prospects and can be used as a potential candidate for nanomedicines combined with fish feed. These new ideas can be studied further before being utilized commercially in the aquaculture fish feed industries and it has huge merit in the future aquaculture need to be considered.

Published: July 2023

The study habits of students are the most important factors that influence the performance of students. Poor study habits are considered one of the main causes of students’ academic failure and can have an important impact on their education and their occupational prospect. Currently, no time bound and elaborative research is found to identify the study habits of undergraduate medical students in Bangladesh. This descriptive-type of cross-sectional study was conducted in different medical colleges with the objective to find out the study habits of undergraduate medical students of Bangladesh. It also aimed to find out if there is any difference in study habits between the students with high, average and below-average grade achievers in professional examinations. Data were collected from 586 conveniently selected students from 10 government and 9 private medical colleges of Bangladesh within the period of one year. A pretested semi-structured, self-administered questionnaire was used for data collection. Study habits were assessed in seven domains namely textbook reading, note-taking, memorizing lessons, paying concentration, exam /test preparation, time management, and classroom-related activities. With regards to study habits, it was revealed that undergraduate medical students have an average study habit score in textbook reading (3.54±1.14), note taking (3.33±1.17), memorizing lessons (3.35±1.17), preparation for the test (3.53±1.18), time management (3.40±1.18) and classroom related activities (3.22±1.2) domains. There is a significant difference in study habit score of high grades and below-average grade achievers in professional examinations. This average score of study habits was below our expectations. This study recommended that teachers should make an effort to develop or improve the study habits of medical students by acquainting them with good and poor/ bad study habits. So that students can identify their poor study habits and can take the appropriate remedial measure. Teachers can guide weak students to develop effective study habits so that students’ learning can be enhanced.

Objecting to Objectivity: Reflecting on Evaluation in Vanuatu
Authors: Nichol Martha , Overton John
Published: July 2023

Evaluation is intended as an objective activity to assess and learn from development interventions. In practice it is donor driven to meet donor needs and is predicated on donor conceptions of knowledge, evidence and meaning. Rejecting the notion of objectivity and viewing evaluation as a reflection of Western epistemologies, this paper draws from observations of two evaluation exercises and several interviews in Vanuatu to highlight a significant shortcoming of current practice: the failure to recognise contextual factors of kastom, place and language. It questions the fundamental approaches to evaluation in different cultural settings and concludes with a call to focus on relationships as a first step toward more inclusive evaluation.

Previous studies related to digestive enzyme activity have been carried out, but there is no information related to the effect of temperature on the trypsin-like activity and digestive amylase in Rsbora lateristriata. Therefore, the purpose of this study was to determine the effect of temperature differences on the activity of trypsin-like and amylase digestion of Rasbora lateristriata fish. The temperature treatments applied were 20, 30, 40, 50, 60, and 70ºC and each treatment was repeated five times. A total of 125 Rasbora fish with a body weight of 0.81 ± 0.09 grams were used in this study. Trypsin-like and amylase activities were measured using a spectrophotometer. The results showed that there were significant differences (p < 0.05) in the trypsin-like and amylase activities at different temperatures. The trypsin-like activity was not significantly different (p < 0.05) between 20-50ºC, but the activity was lower at 60-70ºC. Amylase activity at 30°C and 40°C was not significantly different (p < 0.05), but significantly different from 20, 50, 60, and 70°C. In conclusion, trypsin-like decreased activity at 60°C and amylase at 50°C.

Lichens or lichens are organisms that are the result of a symbiotic relationship between algae (photobionts) and fungi (mycobionts). Because it is very sensitive to pollution, epiphytic lichen is often used as a bioindicator of air pollution in a location. This study aims to determine the types of epiphytic crustose lichen on tea plants in Ngargoyoso District, Karanganyar, Central Java. This study used a population of lichens in the Kemuning Ngargoyoso Tea Plantation, Karanganyar. The sample used was epiphytic crustose lichen at the Kemuning Ngargoyoso Tea Plantation, Karanganyar, and the sampling technique was purposive sampling. In determining the location is divided into 3 stations. Station 1 (900 m asl), station 2 (1,000 m asl), and station 3 (1,100 m asl). Lichen distribution is affected by altitude, therefore more and more lichen colonies are found at higher altitudes. The parameters used in this study were crustose lichen, crustose lichen morphology and crustose lichen habitat. This type of research is descriptive exploratory. The research data obtained were analyzed descriptively qualitatively by presenting them in the form of tables and figures.

Water spinach (Ipomea reptans Poir) is a horticultural product that has high economic and nutritional value for the health of the human body. This research was conducted to determine the effectiveness of the combination of POC Azolla microphylla and tea dregs on the growth of water spinach plants. The research method used was an experiment with a completely randomized design (CRD) with 2 factors including the volume of POC administration which consisted of 4 levels (V0 = control, V1 = 150 ml, V2 = 250 ml, and V3 = 250 ml) and the time interval for giving POC. consists of 2 levels (I1 = 3 days, and I2 = 6 days). The parameters used in this study were plant height, number of leaves, and wet weight. Data were analyzed using Kruskal Wallis. The results showed that giving a volume of 250 ml of POC at intervals of 6 days gave the best results with an average plant height of 8.6 cm, 3 leaves and 0.86 gram fresh weight. Based on this, it can be concluded that the application of liquid organic fertilizer combination of Azolla microphylla and tea dregs is effective for the growth of water spinach plants.
Facilitating Authentic Teaching with 360-Degree Videos

Published: July 2023

Visiting construction sites by civil or construction engineering students is an engaging way to advance students' understanding of construction and structural engineering design practices. Such visits offer a valuable interactive learning opportunity for students to understand real-world projects that scaffolds their in-class theoretical learning. This teaching practice intends to prepare graduate-ready students for the workforce. Facilitating immersive and interactive 360-degree videos are deemed to overcome challenges associated with implementing site visits, including logistics complexity and safety concerns. This paper demonstrated the development and implementation of authentic learning activities incorporating 360-degree videos taken at construction sites for teaching two engineering subjects delivered at La Trobe University-Australia. The construction-site types are selected to serve the intended learning outcomes of civil engineering subjects that teach the structural design methods for steel, timber and reinforced concrete members. The videos are established pedagogically alongside the projects' authentic construction documents, including structural and architectural drawings. These materials are collectively used to establish industry-driven activities for students to learn and practise real-world engineering tasks with onsite exposure enabled through 360-degree videos. Findings from quantitative and qualitative analyses examining students' perceptions of learning from 360-degree videos are reported in this paper. A 10-item survey was created to measure students' reflections on using the 360-degree videos to understand the intended skills, engagement in learning, and the development of their employability skills. From receiving 23 responses to the survey, on average, 94.8% of the participating students reflected their agreement with finding 360-degree videos supporting their understanding, engagement and employability measures, with 80% being in strong to complete agreement.

The ‘ua’u (Hawaiian petrelPterodroma sandwichensis)is an Endangered seabird endemic to the Hawaiian Islands. The at-sea distribution of this species is an under-studied aspect of its ecology. We tracked 10 petrels fledging from the island of Kaua’i to their first wintering grounds, an area which has not previously been described. We also compare birds fledging naturally from their burrows with birds that were grounded by light attraction, rehabilitated, and released. All fledglings travelled over 2000 km southwest after leaving Kaua’i until they reached the Inter-Tropical Convergence Zone and the frontal zone that separates the westward-flowing North Equatorial Current from the eastward-flowing North Equatorial Counter Current. At this point, birds still transmitting turned west, passing through Micronesia before eventually reaching the Philippines. Three birds entered the Lagonoy Gulf in the Philippines, 2 birds briefly entered the South China Sea and the waters off Taiwan, and 1 bird flew up to Japan before returning to the waters off the Philippines. The core use area within the wintering ground was characterized by higher temperatures, lower sea level anomaly, and higher chlorophyllaconcentrations. While wild fledglings transmitted longer than rehabilitated birds, this was only weakly significant, and the fact that several rehabilitated birds made it to their first wintering grounds highlights the importance of rescue and rehabilitation efforts. The potential threats to birds over-wintering in this area include concentrated fishing activity in the Lagonoy Gulf, nocturnal squid fishing vessels across the region, marine pollution, and the impacts of climate change to the region’s marine environment.
Predicting core areas of flatback turtle hatchlings and potential exposure to threats

The lack of data on distribution of juvenile marine species can limit conservation efforts. As hatchlings, marine turtles are too small to track using satellite telemetry, so their at-sea distribution remains unknown. This knowledge gap is critical, as hatchlings already experience high mortality in coastal zones. In addition, further risks to their survival may occur beyond these areas, linked to threats associated with in-water artificial infrastructure and/or attraction to artificial lights and thus increased mortality from higher risk of predation or exhaustion from disorientation. To fill this gap, we used particle tracking forced by an ocean circulation model to predict the dispersal of flatback turtle Natator depressus hatchlings from 12 nesting sites off the coast of Western Australia. We used the model outputs to calculate the distribution of these ‘virtual hatchlings’ and infer the core area of hatchling use over 3 dispersal phases (1-4, 10-15 and 25-30 d). We then calculated the overlap between core areas and 2 anthropogenic threats (in-water artificial infrastructure and light pollution). Core areas were predominately located on the continental shelf during all dispersal phases, supporting the hypothesis that flatback turtles remain in neritic areas. Most (70-80%) of the core area during early dispersal (Days 1-4 and 10-15) contained at least one threat. However, less than half of the area used between Day 25 and 30 was exposed to threats. In the absence of empirical data on hatchling distribution, our results have predicted the core areas used by early life stage flatback turtles to assist in conservation management of these threatened species.
