BUILDING EFFECTIVE CASE STUDIES FOR MATERIALS
Authors: Tam Vivienne , Cerruti Marta 
Published: January 2020

Case studies are used to guide students’ natural curiosity-driven learning instead of traditional content-heavy lectures. In collaboration with Dr. Marta Cerruti and one other co-teacher, I developed case studies for the undergraduate pre-requisite course “Analytical and Characterization Techniques” (MIME 317) to teach the material characterization concepts such as Atomic Absorption or UV/Vis spectroscopy in case-study driven manner. The process included understanding the professors’ desired learning outcomes and finding journal articles that used such concepts to solve real-world problems. Then, I developed handouts to simplify the complicated concepts presented in the articles and crafted questions that students with no background knowledge could still answer given the information provided and the figure/graph from the article. Finally, in delivering the case studies in class, I facilitated group discussion and found that guiding the discussion based on the students’ curiosity deepened their understanding of the subject.
EVOLUTION OF AN INTEGRATED, PROJECT-BASED LOGISTICS ENGINEERING CURRICULUM
Authors: Pasek Zbigniew J. , Pawlewski Paweł 
Published: January 2020

This paper describes the evolution of content and teaching practices of an innovative undergraduate curriculum developed for a new Logistics Engineering degree program. Originally proposed and implemented in 2010, the bi-level curriculum follows European directives and complies with the Bologna Process. Over the years the content and teaching practices were continuously reviewed and modified to stay in sync with teaching practices of design and entrepreneurship, progress simulation technologies, and student responses.
Since the initial introduction of the curriculum many advances in various relevant areas have taken place and consequently the content of the curriculum had to be updated. For example, Lean Startup Method using Business Model Canvas has replaced business plans in teaching entrepreneurship. Similarly, as general softwarebased simulation tools have grown in complexity, teaching them requires more time and becomes time-impractical. A simpler approach based on limited-instruction tools tailored for product assembly, but built on these general simulation platforms, offers a more effective practical solution.
Students’ Grit Level as a Predictor of Their Academic Achievement in Engineering Design Courses
Authors: Galaleldin Mohamed , Anis Hanan 
Published: January 2020

The primary purpose of this study is to explore the relationship between engineering students’ year of study, gender and grit level. This study also aims to assess whether there is any relationship between students’ peer assessment scores in a collaborative project-based learning course and their goal orientation — either towards performance goals or learning goals — and their grit level. The study design is a quasi-experimental design, and the methods used in this study are quantitative. Student grit level was measured using a 12-item scale. The questionnaire was administered in three engineering design courses at different levels of study. The first course is an introduction to engineering design course for firstyear engineering and computer sciences students; the second is an introduction to engineering design course for second-year engineering and computer science students; and the third is a computer-aided design/computer-aidedmanufacturing (CAD/CAM) engineering design capstone course for fourth-year mechanical engineering students. Data collection occurred during the fall semester of 2018- 2019 academic year. Students’ grit level was not found to be a predictor of students’ peer assessment scores, although their goal orientation predicted their level of contribution to their team project.
Personas datu aizsardzības mērķis un tiesiskā regulējuma vēsturiskā attīstība
Authors: Reine-Vītiņa Agnese 
Published: January 2020

Mūsdienās tiesības uz privāto dzīvi nepieciešamas ikvienā demokrātiskā sabiedrībā, un šo tiesību iekļaušana konstitūcijā juridiski garantē fiziskas personas rīcības brīvību un vienlaikus arī citu – valsts pamatlikumā noteikto – cilvēka tiesību īstenošanu [5]. Personas datu aizsardzības institūts tika izveidots, izpratnes par tiesību uz personas privātās dzīves neaizskaramību saturu paplašinot 20. gadsimta 70. gados, kad vairāku Eiropas valstu valdības uzsāka informācijas apstrādes projektus, piemēram, tautas skaitīšanu u. c. Informācijas tehnoloģiju attīstība ļāva arvien vairāk informācijas par personām glabāt un apstrādāt elektroniski. Viena no tiesību problēmām bija informācijas vākšana par fizisku personu un tiesību uz privātās dzīves neaizskaramību ievērošana. Lai nodrošinātu privātās dzīves aizsardzību, atsevišķas Eiropas valstis pēc savas iniciatīvas pieņēma likumus par datu aizsardzību. Pirmie likumi par personas datu aizsardzību Eiropā tika pieņemti Vācijas Federatīvajā Republikā, tad Zviedrijā (1973), Norvēģijā (1978) un citur [8, 10]. Ne visas valstis pieņēma likumus par datu aizsardzību vienlaikus, tāpēc Eiropas Padome nolēma izstrādāt konvenciju, lai unificētu datu aizsardzības noteikumus un principus.

Nowadays, the right to privacy is indispensable in every democratic society and inclusion of such rights in the constitution, guarantees legally freedom of action of a natural person and, simultaneously, implementation of other human rights established in the fundamental law of the state. The institute of personal data protection was established by expanding the understanding of the content of the right to privacy in the 70’s of the 19th century, when the government of several European countries initiated information processing projects, such as population census etc. For the development of information technology, more and more information on persons was kept and processed in electronic form. One of the legal problems was gathering of information on natural persons and the right to privacy. In order to ensure the protection of privacy, separate European countries, on their own initiative, established a law on data protection. The first laws on the protection of personal data in Europe were established in the Federal Republic of Germany, then in Sweden (1973), Norway (1978) and elsewhere. Not all countries adopted laws on data protection at the same time, so the Council of Europe decided to elaborate a convention to unify data protection rules and principles.
Ieguldītāju aizsardzības mehānisma attīstības tendences: normatīvo aktu grozījumi 2017. un 2018. gadā

Published: January 2020

Ieguldītāju aizsardzības mehānisms ir diezgan jauns tiesību institūts,  kura elementi ietverti vairākos Latvijas Republikas un Eiropas Savienības normatīvajos aktos. Ieguldītāju aizsardzības problemātikas aktualitāti veicina gan globalizācija, gan tehnoloģiju attīstība, kā arī jaunu finanšu instrumentu veidu rašanās. Ieguldītāju aizsardzības pasākumu attīstību Latvijas tiesiskajā regulējumā būtiski ietekmē Eiropas Savienības normatīvā regulējuma pārņemšana nacionālajā tiesī­bu sistēmā.  Šajā rakstā skartas personu kā ieguldītāju tiesības, kas cieši saistītas ar vērts­papīru kā patstāvīgu privāttiesiskas apgrozības priekšmetu, t. i., ieguldītāju aizsardzības pamatelementi aplūkoti ieguldījumu pakalpojumu kontekstā. Taču šeit netiek aplūkotas akcionāru, obligacionāru, ieguldījumu apliecību īpašnieku tiesības, kas izveidojas no īpašumtiesībām uz vērtspapīriem ar tieši vērtspapīrā nostiprinātajām tiesībām (piemēram, ar izpirkuma tiesībām, balsstiesībām, tiesībām uz informāciju u. c.).

Mechanism of the investor protection is a quite new law institute. The elements of the investor protection mechanism could be found in various legal acts both at the state level of the Republic of Latvia and at the level of the EU. Globalisation, technical developments and arising of new types of financial instruments encourage actualisation of investor protection problematics.  The development of the measures related to the investor protection are influenced by the transportation of the EU legal acts into national law systems. The article is devoted to the rights of investors as elements of investor protection mechanisms in the aspect of providing of investment services to the investors.

Politiskās plānošanas dokumentos tiek atzīts, ka Latvijā samazinās juridiskās izglītības kvalitāte un tiesību zinātņu studiju programmu absolventiem ir vājas zināšanas un prasmes jurisprudencē.  Lai paaugstinātu juridiskās izglītības kvalitāti, Latvijas Republikas Ministru kabinets 2015. gadā akceptēja rīkojumu par valsts vienotā jurista kvalifikācijas eksāmena ieviešanu 2021. gadā profesionālajās maģistrantūras studiju programmās “Tiesību zinātne”, vienlaikus augstākās izglītības sistēmā likvidējot profesionālās bakalaura studiju programmas un liedzot studējošajiem iespēju iegūt juriskonsulta kvalifikāciju. Augstākās juridiskās izglītības sistēma kopumā tiek pārveidota. Valsts vienotā jurista kvalifikācijas eksāmena ieviešana rada nepieciešamību pārveidot studiju procesu, veikt izmaiņas īstenotajos studiju kursos un papildināt prasības tiesību apakšnozarēs, kurās tiks pārbaudītas studējošo zināšanas vienotā eksāmenā.

Political planning documents recognise that quality of legal education is decreasing in Latvia, graduates of law study programmes have poor knowledge and skills in jurisprudence. In order to increase the quality of legal education, the Cabinet of Ministers of the Republic of Latvia in 2015 accepts the order on the introduction of the State Unified Lawyer’s Qualification Exam in 2021 in the professional Master’s study programme “Law Science”. At the same time, the higher education system eliminates professional bachelor study programmes and prevents students from gaining legal counsel. The higher legal education system as a whole is transformed. The introduction of the State Jurisprudence Expert Examination determines the necessity to transform the study process, to make changes in the study courses to be implemented, to supplement the requirements in the sub-branches of law, where students’ knowledge in a single examination will be checked. Currently, it is too early to conclude whether the introduction of a single national lawyers’ qualification examination will increase the quality of legal education, and graduates of legal science study programmes will increase their knowledge and skills in jurisprudence.

Objetivo: Avaliar os níveis circulantes dos hormônios sexuais e da prolactina em pacientes com psoríase em comparação com controles saudáveis e determinar a correlação entre os níveis desses hormônios e a gravidade da doença. Métodos: Os níveis de estrogênio, progesterona, testosterona, hormônio folículo estimulante (FSH), hormônio luteinizante (LH) e prolactina (PRL) foram medidos em 40 pacientes com psoríase e 20 controles saudáveis. Resultados: Observou-se que os pacientes com psoríase apresentaram maiores níveis séricos de FSH e LH e menores de testosterona e estrogênio em relação aos controles saudáveis, embora essa diferença não tenha sido estatisticamente significativa. Não houve diferenças nos níveis de progesterona entre os 2 grupos avaliados. No entanto, os níveis séricos de prolactina foram significativamente maiores entre os pacientes com psoríase quando comparado aos controles saudáveis. Além disso, uma correlação positiva estatisticamente significante foi encontrada entre a prolactina e o PASI (Índice de gravidade da psoríase por área). Conclusão: Nesse sentido, infere-se que a prolactina possa desempenhar um papel na etiopatogenia da psoríase. No entanto, estudos de seguimento a longo prazo são necessários para validar a importância dessas associações.

Authors: K.K Sheema , M Dorai 
Published: January 2020

Aquaponics is an intensive sustainable food production system that combines aquaculture and hydroponics, in which fish and plants grow together symbiotically. In an aquaponic unit, the effluent rich nutrients derived from nitrogenous waste excreted from fish, fish feed and decomposing organic matter,fertilizes hydroponic beds providing essential nutrients for plant growth. Simplified raft aquaponic system vary greatly in design and construction, but perform all key functions of plant and fish production, removal of suspended solids and bacterial nitrification. All life forms require nitrogen as an integral part of proteins and nucleic acids, therefore all living organisms are involved in the nitrogen cycle. This process is primarily accomplished by two groups of autotrophic nitrifying bacteria that can build organic molecules and utilize CO2 as the carbon source for biosynthesis and oxidation of nitrogen compounds as the energy source. Abroad range of major parameters and factors affecting bacterial growth has been studied in this paper which are essential for nitrification, that include healthy biofilter with appropriate water conditions like, water temperature, pH, dissolved oxygen (DO), total nitrogen concentrations. Characterization and identification of bacterial populations in an aquaponics system has been carried out by cultivation-dependant techniques and traditional methods of analyzing microbial communities using standard light microscopy.

Phosphorus (P) is one of the essential nutrients that functions is metabolism in plant. Based on these functions, it indicates that nutrient P has an important role for plant growth and production. However, its availability in soil is very low, which is less than 0.01% of the total P. Therefore, the availability of P nutrients in the soil needs to be increased by increasing the activity of soil microorganisms through the use of phosphate solubilization bacteria. This research is aimed to show the changes in the physiological characteristics of tomato plants through the application of phosphate solubilization bacteria and rock phosphate. Experiment using factorial randomized block design (RBD) which consisted of 2 factors with 2 consultation levels on the first factor (phosphate solubilization bacteria) and 4 levels on the second factor (rock phosphate), and it consist of 8 combinationed of phosphate solubilization bacteria and rock phosphate with 3 replicated.

Preparation, micro-structure and mechanical properties of porous carbonate apatite using chicken bone as raw material
Authors: Nguyen Tram Xuan Thanh 
Published: January 2020

Introduction: The increasing in bone loss due to trauma disease or accident leads to the demand for bone substitute materials. Autograft is the gold standard for bone graft; however, it has limited supplies and additional surgery for harvesting. Therefore, the artificial bone graft is necessary for bone defect treatment. One of the potential candidates for bone repair and regeneration is porous Carbonate Apatite (CO3Ap) due to its excellent biodegradability and biocompatibility. Understanding the importance of recycling of waste materials and by-products from the food industry such as poultry bone could be used as the alternative source for starting material. Thus, recycling and adding value for the food waste could be done with the development of artificial bone graft.
Method: In this study, porous CO3Ap was prepared using bio apatite powder derived from chicken bone via the sacrificial template technique. Templates such as chopped cotton fibers were used to make porous CO3Ap with interconnecting pores. X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used to characterize phase composition and structure. Carbonate content was evaluated using elemental analysis CHN (carbon hydrogen and nitrogen) analyzer.
Results: The results indicated that a pure CO3Ap block consisting of elongating pores could be obtained. Mechanical strength was evaluated in terms of Diametral Tensile Strength (DTS). Porous CO3Ap had a mean DTS value of 198.5 +/- 12.9 kPa and an average porosity of approximately 70%.
Conclusion: As a conclusion, CO3Ap containing 5.25 ± 0.03 % wt of carbonate with low crystallinity and the inter-connecting porous structure is advantageous on bone regeneration as being a useful material for application to repair the bone defect.
