”Du skal ikke stikke næsen for langt frem”: Et studie af normer for deltagelse og forberedelse blandt førsteårsstuderende
Authors: Bager Anna Juul , Herrmann Kim Jesper 
Published: September 2021

Studerende på videregående uddannelser forventes at deltage aktivt i undervisningen og tage ansvar for egen læring. Alligevel oplever undervisere ofte, at studerende er meget tilbageholdende i timerne. Dette studie undersøger, hvilken roller normer spiller for studenteraktivitet. Tolv studerende blev interviewet to gange i løbet af et semester. Det viste sig, at normer havde en stor adfærdsregulerende rolle, ligesom det viste sig, at der var en betydelig forskel mellem udtalte og uudtalte normer. Den observation, der overraskede os mest, var, at der var meget snævre rammer for legitim delta­gelse på holdtimerne, mens der var meget vide rammer for ikke-del­ta­gel­se. Disse præliminære resultater kalder på en diskussion af, hvordan normen om ansvar for egen læring fortolkes og praktiseres af universitetsstuderende. The aim of Danish universities is to encourage students to become active, independent, and responsible learners; yet, university teachers often encounter students that are very reluctant to participate in discussions. This study examines how norms influence student engagement in classes. Twelve students were interviewed twice during their second semester. The study suggests that norms regulate behaviour and furthermore the study uncovered a demarcation between spoken and unspoken norms. To our surprise, we found there to be strict boundaries for legitimate participation in discussion, while there was a high tolerance for non-participation. These results – although preliminary – call for a discussion of how the tenets of independence and responsibility are conceived by students.
Aktiv lytning i ph.d.-vejledning - et værktøj til udvikling af dialogiske kompetencer
Authors: Godskesen Mirjam , Wichmann-Hansen Gitte 
Published: September 2021

Begge forfattere har mange års erfaring med udvikling og afholdelse af kurser om ph.d.-vejledning og interesserer sig for, hvordan vejledningsprak­­sis bedst udvikles og forandres. I denne artikel stilles der skarpt på, hvordan man kan forstå aktiv lytning som ét blandt mange elementer i ph.d.-vejledningsprocessen, og i hvilken grad metoden kan understøtte udvikling af ph.d.-vejlederens dialogiske kompetence. Der rapporteres udvalgte hovedresultater fra et evalueringsstudie, som nyligt er blevet gennemført blandt deltagere fra syv ph.d.-vejledningskurser afholdt på DTU i perioden 2010-2012. I lyset heraf diskuteres hvorfor vejlederne er så optagede af aktiv lytning, og hvad der kan forklare metodens popularitet. Both authors have organized and presented courses on PhD supervision for many years, and our research interests cover the development of and changes to supervision practices. In this article, we focus on how to understand active listening as one among many elements of the PhD supervision process and the extent to which the method can support the development of doctoral supervisor's dialogical competence. We report selected results from an evaluation study we recently conducted among participants from seven PhD supervision courses held at DTU between 2010-2012. With reference to this data, we discuss why supervisors are so interested in active listening and how the popularity of the method can be explained.
”De sidder i deres egen lille gruppe ovre i hjørnet”– en pilotundersøgelse af etniske minoritetsstuderendes møde med studie- og undervisningsmiljøet på farmaceutstudiet
Authors: Hansen Gro Inge 
Published: September 2021

I artiklen fokuseres på, hvordan studie- og undervisningsmiljøet på farmaceutstudiet på Københavns Universitet (KU) kan risikere at danne ramme for en adskillelse mellem etniske minoritetsstuderendes og etnisk danske studerendes faglige og sociale studieliv. Der argumenteres for, hvordan dette kan påvirke etniske minoritetsstuderendes uddannelsesudbytte og i værste fald bevirke, at de dropper ud af deres studie. Afslutningsvis perspektiveres omkring, hvad man kan gøre for at mindske disse skel i studie- og undervisningsmiljøet på farmaceutstudiet. Udgangspunktet for denne artikel er en kvalitativ pilotundersøgelse udført i forbindelse med et speciale om studiepraksis og pædagogisk praksis på medicinstudiet og på farmaceutstudiet på KU. The academic environment at the University of Copenhagen’s School of Pharmaceutical Sciences may contribute to a separation between ethnic minority students and ethnic Danish students in both social and vocational settings. This article examines how this could affect ethnic minority students’ educational outcomes, and in a worst-case scenario lead to their dropout of the School of Pharmaceutical Science. . A number of suggestions to address the situation are outlined. The article is based on a qualitative pilot analysis carried out as a part of a Master thesis about study practices and pedagogical practices in the Medicine Program at the Panum Institute and the School of Pharmaceutical Science at the University of Copenhagen.
Progression på tid og på tværs. Fremdrift og fleksibilisering som styringsregime på de videregående uddannelser
Authors: Sarauw Laura Louise 
Published: September 2021

Med den kommende studiefremdriftsreform følger både krav om hurtigere gennemførelse og en fleksibilisering af systemet, der skal lette meritoverførslen og gøre det nemmere at sammenstykke en uddannelse på tværs af institutioner og uddannelser. Artiklen diskuterer de nye tiltag som en bestemt styring af de studerendes uddannelsesnavigation: Hvad sker der, når vi giver den enkelte studerende større frihed til at sammensætte uddannelse på tværs af moduler, der ikke har nogen på forhånd tilrettelagt (faglig) progression mellem sig? Vil den øgede valgfrihed medvirke til at motivere de studerende, højne gennemførelsen og gøre dem mere arbejdsmarkedsparate, sådan som regeringen fremlægger det? Og er prisen i givet fald en fragmentering af viden og instrumentel overfladelæring blandt de studerende, sådan som kritikerne foreslår? The aim of the so-called ‘speed-up’ reform is to cut the time available for students to complete their university studies. One consequence of the reform is the increased requirement for flexibility within the Danish higher education system. To cope with the reform, the system will need to facilitate transfer of credits and make it easier for students to compose more personalized learning portfolios, which can include courses from different institutions and study programmes. The article discusses the possible implications of this new approach to steering students through the higher education system: What happens when we allow the individual student to compose a personal profile from different modules with no intentional progression between them? Will the students’ increased freedom serve to motivate them, make them complete their studies more quickly and make them more fit for the labour market like the Danish government presumes? Or will this be at the expense of leaving students with fragmented knowledge and superficial understandings as suggested by the critics?

Authors: Michelsen Claus , Dyrberg Nadia Rahbek 
Published: September 2021

Ved Det Naturvidenskabelige Fakultet, Syddansk Universitet, blev trefasemodellen anvendt som et didaktisk redskab til at understøtte progression i de studerendes læring lokalt i de enkelte faglige forløb på første studieår 2012/13. Artiklen beskriver baggrunden for og udviklingen af trefasemodellen og præsenterer med udgangspunkt i de studerendes evalueringer de første erfaringer med modellen. In the academic year 2012/13 the Faculty of Science at the University of Southern Denmark, implemented a didactical tool called the three phase model. The model was used to track the progress of first year students on the university’s academic courses. The paper describes both the incentive for and the development of the three phases model and presents preliminary results based on the evaluations of the first cohort of students.

Authors: Aydin Cil Mevra , Ghosi Ghareaghaji Atena , Bayir Yasin , Buyuktuncer Zehra , Besler Halit Tanju 
Published: September 2021

Backround
This study aimed to determine the effects of LC n-3 PUFA supplementation on the prevention and treatment of obesity and obesity-related diseases, and to compare the efficiency of different LC n-3 PUFA sources via biochemical and genetic mechanisms in rats.

Methods
Male Wistar rats were randomized into four study groups, and fed with a standard diet, High Fat Diet (HFD), HFD+%2.5 Fish Oil (FO-HFD) or HFD+%2.5 Krill Oil (KO-HFD) for eight weeks. Food consumption, weight gain, serum glucose, insulin, ghrelin and leptin concentrations, lipid profile, liver fatty acid composition, and FADS1 and FADS2 mRNA gene expression levels were measured.

Results
Weight gain in each HFD group was significantly higher than control group (p < 0.001), without any differences among them (p < 0.05). LC n-3 PUFAs modified lipid profile, but not glucose tolerance. Serum leptin levels were significantly higher in HFD groups than in the control group, however, no difference in serum ghrelin levels was observed among the groups. Liver n-3 fatty acid desaturation activity was higher (p = 0.74), and liver total lipid content was lower (p = 0.86) in KO-HFD compared to FO-HFD. FADS1 gene expression was highest in the HFD group (p < 0.001) while FADS2 gene expression was highest in the FO-HFD group (p < 0.001).

Conclusion
LC n-3 PUFAs, especially krill oil, had moderate effects on lipid profile, but limited effects on obesity related parameters, suggesting different effects of different sources on gene expression levels. Further randomized controlled trials are needed to determine the efficacy of different LC n-3 PUFA sources in the prevention and treatment of obesity in humans.

Aims: Analyze and relate the general index of climate change and sustainable development of Peru and its departments during the year 2006 - 2018.
Study Design: The research is not intended to deliberately manipulate the variables, therefore, it is non-experimental; is descriptive, correlational and longitudinal.
Place and Duration of Study: The research project was carried out in the Faculty of Forestry and Environmental Sciences of the UNCP, likewise the collection of information data was carried out during 2020 and 2021, due to the Covid19 pandemic.
Methodology: Two economic data, four social data and five environmental data were selected, in addition climatic data of precipitation, maximum and minimum temperature of the 24 departments of Peru were collected during the years 2006 - 2018; To estimate the climatic and sustainable indices, the Prescott-Allen methodology was applied, the interpretation and assessment scale (climate change and sustainable development) was carried out using the barometric analysis of McCarthy. Five regression models were applied [dependent variable GISD; independent variable IGCC], hypothesis testing was performed using Karl Pearson's r coefficient and p-value at 0.05.
Results: It is stated that Peru presents an economic sustainable index [EcSI] of 0.066 low, social sustainability [SoSI]: 0.225 medium, environmental sustainability [EnSI]: 0.282 high and general index of sustainable development [GISD] is 0.572 medium. In itself the climate index of precipitation is [CPrI]: 0.079 weak, the climate index maximum temperature [CTxI]: 0.251 severe, climate index minimum temperature [CTnI]: 0.138 weak and the general index of climate change [GICC] is 0.468 moderate. Two appropriate regression models [linear and exponential] were determined to estimate the GISD as a function of the GICC, CPrI, CTxI and CTnI.
Conclusion: It was found that during the year 2006 to 2018 Peru presented a low economic, social medium, high environmental situation and therefore its sustainable development is in a medium situation; while precipitation is weak, severe maximum temperature, weak minimum temperature, and therefore, climate change has a moderate impact. Likewise, it is stated that there are two linear and exponential regression models to estimate the GISD based on the GICC, CPrI, CTxI and CTnI. It is recommended to collect more climatic data and economic indicators to be able to differentiate the economic and climatic situation that Peru and departments represent during its thirteen years of development.

The rapid population growth has driven the demand for more food, fiber, energy, and water, which is associated to an increase in the need to use natural resources in a more sustainable way. The growing connectivity in the rural environment, in addition to its greater integration with data from sensor systems, remote sensors, equipment, and smart-phones have paved the way for new concepts from the so-called digital agriculture. The information that crops offer is turned into profitable decisions only when efficiently managed. Current advances in data management are making Smart Farming grow exponentially as data have become the key element in modern agriculture to help producers with critical decision-making. Valuable advantages appear with objective information acquired through sensors with the aim of maximizing productivity and sustainability. These kind of data-based managed farms rely on data that can increase efficiency by avoiding the misuse of resources and the pollution of the environment. Data-driven agriculture, with the help of robotic solutions incorporating artificial intelligent techniques, sets the grounds for the sustainable agriculture of the future. Digital agriculture offers far-reaching opportunities for accelerating agricultural transformation. Although there are concerns that digital agriculture will enhance the market power of large agribusiness enterprises and increase the digital divide, a combination of new actors and public action can help accelerate the supply of digital agricultural technology, manage threats of market concentration, and harness the opportunities of digital agriculture for all.
The agriculture industry has radically transformed over the past 50 years. Advances in machinery have expanded the scale, speed, and productivity of farm equipment, leading to more efficient cultivation of more land. Seed, irrigation, and fertilizers also have vastly improved, helping farmers increase yields. Now, agriculture is in the early days of yet another revolution, at the heart of which lie data and connectivity. Artificial intelligence, analytics, connected sensors, and other emerging technologies could further increase yields, improve the efficiency of water and other inputs, and build sustainability and resilience across crop cultivation and animal husbandry. This paper reviews the current status of advanced farm management systems by revisiting each crucial step, from data acquisition in crop fields to variable rate applications, so that growers can make optimized decisions to save money while protecting the environment and transforming how food will be produced to sustainably match the forthcoming population growth.

Published: September 2021

Research related to the geothermal system in the Tiris geothermal area (TGA) Probolinggo Regency has been conducted using the gravity method. This study aims to investigate the subsurface structure, with a target on estimating geothermal reservoir rocks from the study area. This study utilized the Gravity meter La Coste & Romberg type G-1503 on 116 acquisition points in an area of 2.16 km2, covering all geothermal manifestation points in TGA. The gravity measurement data obtained is then processed through gravity corrections, which include: conversion into milli-Gals (mGal) units, tidal correction, drift correction, latitude correction, free air correction, Bouguer correction, and terrain correction. These corrections to obtain a complete Bouguer anomaly (CBA) value. The study area shows the CBA value on a horizontal plane which ranges from 0.1 mGal to 4.2 mGal. The separation of the regional and residual Bouguer anomaly from the CBA on a horizontal plane employed the Moving Average method through spectrum analysis. The value of residual Bouguer anomaly ranges from -0.7 mGal to 2.7 mGal. The low anomalies are scattered in the northwest, and a small number are spread in the northeast and southeast, while the high anomalies are in the middle of the study area. The result of 3D inversion modeling finds that the study area's subsurface structure consists of four rock layers, namely lapilli tuff, tuffaceous breccia, volcanic breccia, and basalt. Volcanic breccia is approximated as geothermal reservoir rocks at a depth of 700 to 1000 meters below the acquisition point. In contrast, basalt is supposed to be intrusive igneous rock because it tends to break through the surface at a depth of 348 to 350 meters below the acquisition point. The presence of these intrusive rocks can be predicted through spectrum analysis result, which shows a regional anomaly source at a depth of 348 meters below the acquisition point. This intrusion rock is suspected to be a heat source rock in the geothermal system in the study area.

AbstractProgress toward developing metal implants as permanent hard‐tissue substitutes requires both osteointegration to achieve load‐bearing support, and energy‐dissipation to prevent overload‐induced bone resorption. However, in existing implants these two properties can only be achieved separately. Optimized by natural evolution, tooth‐periodontal‐ligaments with fiber‐bundle structures can efficiently orchestrate load‐bearing and energy dissipation, which make tooth–bone complexes survive extremely high occlusion loads (>300 N) for prolonged lifetimes. Here, a bioinspired peri‐implant ligament with simultaneously enhanced osteointegration and energy‐dissipation is presented, which is based on the periodontium‐mimetic architecture of a polymer‐infiltrated, amorphous, titania nanotube array. The artificial ligament not only provides exceptional osteoinductivity owing to its nanotopography and beneficial ingredients, but also produces periodontium‐similar energy dissipation due to the complexity of the force transmission modes and interface sliding. The ligament increases bone–implant contact by more than 18% and simultaneously reduces the effective stress transfer from implant to peri‐implant bone by ≈30% as compared to titanium implants, which as far as is known has not previously been achieved. It is anticipated that the concept of an artificial ligament will open new possibilities for developing high‐performance implanted materials with increased lifespans.

Published: September 2021

AbstractNanostructured piezoelectric semiconductors offer unprecedented opportunities for high‐performance sensing in numerous catalytic processes of biomedical, pharmaceutical, and agricultural interests, leveraging piezocatalysis that enhances the catalytic efficiency with the strain‐induced piezoelectric field. Here, a cost‐efficient, high‐performance piezo‐electrocatalytic sensor for detecting l‐ascorbic acid (AA), a critical chemical for many organisms, metabolic processes, and medical treatments, is designed and demonstrated. Zinc oxide (ZnO) nanorods and nanosheets are prepared to characterize and compare their efficacy for the piezo‐electrocatalysis of AA. The electrocatalytic efficacy of AA is significantly boosted by the piezoelectric polarization induced in the nanostructured semiconducting ZnO catalysts. The charge transfer between the strained ZnO nanostructures and AA is elucidated to reveal the mechanism for the related piezo‐electrocatalytic process. The low‐temperature synthesis of high‐quality ZnO nanostructures allows low‐cost, scalable production, and integration directly into wearable electrocatalytic sensors whose performance can be boosted by otherwise wasted mechanical energy from the working environment, for example, human‐generated mechanical signals.

AbstractA chlorin‐carotenoid dyad Dyad‐COOH possessing a C32‐carboxylic acid group and a carotenoid moiety at the terminal end of C17‐substituent is synthesized from naturally occurring chlorophyll‐a as a new sensitizer for photocatalytic hydrogen evolution (PHE). Under the same experimental conditions, a maximum turnover number (TON) of PHE based on Dyad‐COOH/Pt/TiO2 is much higher than those of Pt/TiO2‐based photocatalysts sensitized by the corresponding chlorin carboxylic acid (Chl‐COOH) without carotenoid side chain, sole carotenoic acid (Car‐COOH), or their 1:1 (mol/mol) mixture. By co‐adsorbing different types of carboxylic acid, the TON of Chl‐COOH is found to be increased probably due to the suppression of chlorin aggregates on the TiO2 surface. The Dyad‐COOH/Pt/TiO2 exhibits excellent photocatalytic performance with the hydrogen evolution of 9147 µmol g−1 h−1 with TON of 425 when 43 µmol g−1 of dye is loaded on the Pt/TiO2 catalyst, while a better TON of 556 is achieved by preparing the photocatalyst with 10 µmol g−1 of Dyad‐COOH. This study provides new ideas for utilizing traditional photosynthetic dyes to a low‐cost and highly‐efficient photosensitizer for PHE.
