Abstract
In the present investigation, Achromobacter denitrifacians was isolated from industrial wastewater and used in the degradation of para nitro-phenol. Experiments were made as a function of different carbon sources, organic and inorganic nitrogen sources and metal ions to analyse the removal efficiency of para nitro-phenol present in the industrial wastewater sources. Observations revealed that the rate of phenol biodegradation was significantly affected by pH, temperature of incubation, glucose, peptone and metal ion concentration. The optimal conditions for phenol removal were found to be pH of 7.5, temperature, 35 °C and 0.25 gL−1 supplemented glucose level, 0.25 gL−1 supplemented peptone level, and 0.01 gL−1 zinc ion. The key importance of the present study is the utilization of a native bacterial strain isolated from the industrial effluent water itself having an impending role in the bioremediation process of phenol.

:
Exosomal vesicles enclose and carry a broad range of biological molecules,
such as nucleic acids, lipids, and proteins, and transfer them between cells. In cancer,
cells being mentioned could be neighbors in the same tumor microenvironment
communicating with each other, or they could be localized at distant sites of the body,
enabling suitable conditions for metastasis. Either way, it is a concrete fact that cells
under physiological or pathological conditions make crosstalk via exosomal secretion.
This review looks at the relation between exosomal cargo and mechanisms of cancer
through recent research.
Applying Mobile Technology to Sustain Physical Activity After Completion of Cardiac Rehabilitation: Acceptability Study
Authors: Elnaggar Abdelaziz , von Oppenfeld Julia , Whooley Mary A , Merek Stephanie , Park Linda G 
Published: September 2021

Background
Many patients do not meet the recommended levels of physical activity after completing a cardiac rehabilitation (CR) program. Wearable activity trackers and mobile phone apps are promising potential self-management tools for maintaining physical activity after CR completion.

Objective
This study aims to evaluate the acceptability of a wearable device, mobile app, and push messages to facilitate physical activity following CR completion.

Methods
We used semistructured interviews to assess the acceptability of various mobile technologies after participation in a pilot randomized controlled trial. Intervention patients in the randomized controlled trial wore the Fitbit Charge 2, used the Movn mobile app, and received push messages on cardiovascular disease prevention and physical activity for over 2 months. We asked 26 intervention group participants for feedback about their experience with the technology and conducted semistructured individual interviews with 7 representative participants. We used thematic analysis to create the main themes from individual interviews.

Results
Our sample included participants with a mean age of 66.7 (SD 8.6) years; 23% (6/26) were female. Overall, there were varying levels of satisfaction with different technology components. There were 7 participants who completed the satisfaction questionnaires and participated in the interviews. The Fitbit and Movn mobile app received high satisfaction scores of 4.86 and 4.5, respectively, whereas push messages had a score of 3.14 out of 5. We identified four main themes through the interviews: technology use increased motivation to be physically active, technology use served as a reminder to be physically active, recommendations for technology to improve user experience, and desire for personal feedback.

Conclusions
By applying a wearable activity tracker, mobile phone app, and push messages, our study showed strong potential for the adoption of new technologies by older adults to maintain physical activity after CR completion. Future research should include a larger sample over a longer period using a mixed methods approach to assess the efficacy of technology use for promoting long-term physical activity behavior in older adults.
Ecological Momentary Assessment of Bipolar Disorder Symptoms and Partner Affect: Longitudinal Pilot Study

Published: September 2021

Background
The World Health Organization ranks bipolar disorder (BD) as the 7th leading cause of disability. Although the effects on those with BD are well described, less is reported on the impact of BD on cohabiting partners or any interactions between the two; this requires in vivo data collection measured each day over several months.

Objective
We set out to demonstrate the utility of ecological momentary assessment with BD couples measured using yoked smartphone apps. When randomly prompted over time, we assumed distinct patterns of association would emerge between BD symptoms (both depression and hypo/mania) and partner mood (positive and negative affect).

Methods
For this pilot study, we recruited an international sample of young and older adults with BD and their cohabiting partners where available. Both participants and partners downloaded separate apps onto their respective smartphones. Within self-specified “windows of general availability,” participants with BD were randomly prompted to briefly report symptoms of depression and hypo/mania (ie, BDSx), positive and negative mood (ie, POMS-15; partners), and any important events of the day (both). The partner app was yoked to the participant app so that the former was prompted roughly 30 minutes after the participant with BD or the next morning if outside the partner’s specified availability.

Results
Four couples provided 312 matched BD symptom and partner mood responses over an average of 123 days (range 65-221 days). Both were GPS- and time-stamped (mean 3:11 hrs between questionnaires, SD 4:51 hrs). Total depression had a small but significant association with positive (r=–.14; P=.02) and negative partner affect (r=.15; P=.01]. Yet total hypo/mania appeared to have no association with positive partner affect (r=–.01; P=.87); instead, negative partner affect was significantly correlated with total hypo/mania (r=.26; P=.01). However, when we look specifically at BD factors, we see that negative partner affect is associated only with affrontive symptoms of hypo/mania (r=.38; P=.01); elation or loss of insight appears unrelated to either positive (r=.10; P=.09) or negative partner affect (r=.02; P=.71). Yet affrontive symptoms of hypo/mania were significantly correlated with negative affect, but only when couples were together (r=.41; P=.01), not when apart (r=.22; P=.12). That is, these angry interpersonal symptoms of hypo/mania appear to be experienced most negatively by spouses when couples are together.

Conclusions
These initial findings demonstrate the utility of in vivo ambulatory data collection in longitudinal mental health research. Preliminary analyses suggest different BD symptoms are associated with negative and positive partner mood. These negative effects appear greater for hypo/mania than depressive symptoms, but proximity to the person with BD is important.

Published: September 2021

Monsoon currents and Indonesian Throughflow (ITF) have an essential role in the current Indonesian water system. The movement of current/water masses with non-uniform bathymetric conditions will affect the water column's stability in Indonesian waters. Therefore, this study aims to obtain the current dynamics and stability of the water column in Indonesian waters, based on a hydrodynamic model termed the HAMburg Shelf Ocean Model (HAMSOM). The results of the model are data of current, temperature, salinity, and density. The data is used to study the dynamics of seawater in Indonesian waters. The water column's stability is examined by calculating the Brunt Väisälä frequency values (N2) based on the density data generated. The results show that monsoon currents were stronger in shallow waters because the stratification did not change. Meanwhile, the maximum N2 value occurs at the surface to a depth of 80-100 m with a range of 0.0000-0.0006 cycle s-1. The study also produces an understanding of the condition of Indonesia's stability (N2 positive), both spatially and temporally.

The Madden-Julian Oscillation and Cold Surge phenomena have been known to cause increased rainfall, with the capacity to trigger hydrometeorological disasters, in western Indonesia. However, further investigations are required regarding the interaction between these phenomena on rainfall pattern. Therefore, this study aims to analyze the interaction between MJO and CS over western Indonesia, particularly by using land-based rainfall observation data from multiple stations, as previous studies were dominated by the use of gridded data from remote observations. This study utilized in-situ observation data obtained from 4329 weather observations and rain stations between 1989 and 2018. Subsequently, quality control performed based on data availability exceeding 70% over a 30-year period resulted in 303 selected stations to be used for further analysis. Meanwhile, the RMM index, as well as reanalysis data of mean sea level pressure and 925 hPa meridional wind, were also applied for MJO and CS identification. According to the composite analysis, the effect of CS on MJO phases tends to increase precipitation by about 50%, over western Indonesia, with maximum increase ranging from 200 to 400% over the northeastern coast of Sumatra, around Karimata Strait (Riau Islands and West Kalimantan), as well as the northern coast of Java. These areas are exposed to the sea and have direct access to the wind-terrain interaction. In addition, the highest rainfall anomaly due to the MJO-CS interaction occurs around Karimata Strait, followed by northern Sumatra and Java, with spatially averaged rainfall anomaly reaching 5 mm/day over the area.

Abstract The resistivity geoelectric method is one of the geophysical methods that can detect the flow of electricity below the earth's surface. One application of the resistivity geoelectric method is to identify the slip field in landslide prone areas. The research aimed to discover slip area of landslide prone zone at the segment road of Toraja-Mamasa. The results of the geoelectric resistivity measurements are combined with the results of drilling at several points so that there are no errors in the process of rock interpretation which are thought to be the cause of landslides. Information about the soil layers is used to determine the boundaries of instability in the soil layer which can be used as a reference in regional development, especially the Toraja - Mamasa road segment. In this research, it was obtained different resistivity values for each rock. The resistivity variation obtained started from 0 - 978 Ωm. The rock resistivity value in the slip plane at the research location is in the 50-300 Ωm boundary fields. The rocks lithologies are clay sandstones, andesite lava and basalt.

Kerawanan longsor di DAS Bendo termasuk dalam kerawanan kelas sedang hingga tinggi. Sampai dengan saat ini, pemetaan rawan longsor di DAS Bendo baru dilakukan pada skala pemetaan 1:250.000. Penelitian ini bertujuan untuk melakukan pemodelan pemetaan kerawanan longsor di DAS Bendo pada skala semi-detil. Metode yang digunakan dalam penelitian ini adalah optimalisasi model artificial neural network menggunakan certainty factor (C-ANN). Peta kerawanan dibangun berdasarkan faktor pengontrol tanah longsor yang berkorelasi positif terhadap kejadian longsor menggunakan Certainty Factor. Sedangkan pemodelan prediksi kerawanan menggunakan model ANN, khususnya arsitektur BPNN (back-propagation neural network). Hasil pemodelan menunjukkan bahwa model C-ANN (7 variabel independen) memiliki nilai AUC (0,916) lebih tinggi daripada model ANN (0,778). Faktor redundansi data, multikolinieritas data, dan proporsi kejadian longsor terhadap cakupan wilayah penelitian mengakibatkan ketidakpastian dalam data variabel independen.

Junkyard Planet: Using Stories to Teach Managerial Accounting with a Sustainability Theme
Authors: Grimm Stephanie D. 
Published: September 2021

ABSTRACT
Theme-based learning suggests a relatable theme can make course content more applicable, engaging, and memorable. This article discusses how sustainability was integrated into an accounting class using Adam Minter's (2013) book Junkyard Planet, and smaller stories including cases and discussion boards. The stories introduce students to the role businesses have in influencing sustainable development. The stories allow for the consideration of managerial accounting concepts including direct material costs, the tradeoffs between fixed automation costs and variable labor costs, as well as the exploration of ethics, sustainability and the common good. The assignments reflect the principles of liberal learning, which strive to prepare students for work and life through an integrated curriculum. Survey results document students' interest in sustainability and their perceptions of their understanding of accounting concepts increased following the course. This suggests integrated learning activities can enhance both comprehension of accounting content and students' appreciation for sustainability.
Pedagogical Practices of Accounting Departments Addressing AACSB Technology Requirements
Authors: Sarkar Sumantra , Boss Scott R. , Gray Joy 
Published: September 2021

ABSTRACTTechnology skills are essential for accounting professionals and should be equally important in accounting curricula. Institutions measure technology-related curricular innovations in part through compliance with AACSB Standard A5. We investigate efforts to meet the requirements of Standard A5 by surveying AIS educators from 85 universities to examine efforts to prepare for accreditation review related to technology in accounting curricula. Quantitative results suggest that most institutions feel prepared but also provide some contradictory information that, when combined with qualitative feedback, raises questions about the degree of progress in technology integration. Common issues include widespread lack of increased faculty training, over-reliance on AIS classes to meet accreditation standards, and inclusion of basic spreadsheet and visualization skills as “technology” or “data analytics.” We suggest a pathway to improve accounting pedagogy as it relates to technology through phased curricular changes and issue a call for administrators to support increased accounting faculty technology training.
