Da desumanização à criação: a revolução no antropoceno em A nossa alegria chegou, de Alexandra Lucas Coelho
Authors: Rendeiro Margarida
Published: May 2021

A nossa alegria chegou (2018) de Alexandra Lucas Coelho é um romance que se posiciona num horizonte de expectativas face ao impacto negativo da ação humana no planeta na era do Antropoceno. Alendabar, espaço totalmente criado ab novo e que não corresponde a nenhuma área geográfica identificável, reifica o impacto da destruição ambiental a que se soma a desumanização resultante de um capitalismo antropofágico e voraz. Esta desumanização concretiza-se, por um lado, na coisificação dos trabalhadores e, por outro lado, na incapacidade de quem detém o poder de sentir empatia pelo seu semelhante. Este artigo discute que, em A nossa alegria chegou, esta violência apenas pode ser combatida por outras formas de violência que são, em si mesmas, essencialmente regeneradoras. A destruição infligida em Alendabar constrói-se literariamente sobre memórias da exploração, do colonialismo e da opressão que estão presentes na experiência do Sul Global, desenhado e intuído a partir da linha do equinócio. Nas reminiscências de visões ancestrais e de experiências de saberes vividos no sul, resgata-se o valor humano expresso em toda a sua plenitude através de uma revolução radical e violenta, mas regeneradora sob memória simbólica da antropofagia ritualística. Eduardo Viveiros de Castro (2002) afirmou que a antropofagia de Oswald de Andrade é uma reflexão metacultural que produziu uma teoria verdadeiramente revolucionária. Em A nossa alegria chegou, é através das imagens dos corpos devorados e libertos que se chega à ressignificação do antropos como parte da utopia do amor físico, real e inteiro.

Peppermint (Mentha × piperita L.) is cultivated for its benefits in pharmaceutical, medicinal, and cosmetic industries. The well-known essential oil of Mentha × piperita L. is widely produced and used all over the world. The aim of present study was to evaluate the impacts of different concentrations of chitosan on the quality and quantity of the essential oil from the aerial parts of peppermint under inoculation of the rhizomes of peppermint seedlings with arbuscular mycorrhizal fungi. Experimental treatments were arranged as factorial design in a completed random block design. The highest essential oil yield (2.4 mL 100 g–1 dry matter) was obtained from the peppermint plants under foliar sprayed at 5 g L–1 chitosan along the inoculum with arbuscular mycorrhizal fungi. For evaluation of phytochemical characteristics, the contents of the main constituents of the peppermint essential oils such as menthol, menthone, etc. (oxygenated monoterpenes and monoterpenes hydrocarbons) under different treatments were analyzed by GC-FID and GC/MS. Results indicated that using chitosan foliar meaningfully raised the amount of menthol, as the major constituent and quality index (>60% v/w), in the essential oil from the peppermint plants inoculation with arbuscular mycorrhizal, however, the plants under the foliar spray of chitosan (without inoculum) revealed the highest amounts of menthone and limonene. In conclusion, we found that the foliar-applied chitosan along inoculation with arbuscular mycorrhizal fungi can be improved quantity and quality active substances of Mentha × piperita L. such as the contents of essential oil, menthol, and balance menthol/menthone.

This experiment studied the effects of biochar and chicken manure tea compost on growth, productivity, and nutritional traits of tomato (Solanum esculentum MILL). A factorial based experiment within complete randomized block design with three replications was conducted to evaluate the traits. The results showed that the biochar + chemical fertilizer (TIB1) contained the significantly highest values of soil EC (1.81 dsm–1), total N (0.39%), available P (156.92 ppm), available K (442.22 ppm), leaf N (3.54%), leaf K (6.73%), and shoot dry weight (463 g). The treatment of (TIB1) increased the production of tomatoes by 393.9% above the control soil conditions. Signiﬁcant differences in fruit quality were observed. The biochar + chicken manure compost tea (1 : 4) (T3B1) treatment contained the highest values of total polyphenols (378.83 mg) and vitamin C (29.03 mg/100 g–1), it but did not significantly affect total soluble solid and titratable acidity values on average compared with control conditions. However, the application of biochar at 10 tons ha–1 cannot fully substitute for fertilizers. Therefore, nutrition management can be achieved by biochar plus inorganic and organic fertilizer to increase tomato productivity and quality, respectively.
Examining Socio-Demographic Factors in Workplace Deviance among Selected University Workers
Authors: Olasupo Matthew O. , Fagbenro Dare A.
Published: May 2021

Introduction: Despite studies on workplace deviance globally and in an emerging country like Nigeria, the role of socio-demographic factors on dimensions and overall workplace deviance have been largely neglected in the literature. This lacuna hopes to be filled by this present study through examining the role of socio-demographic factors (gender, staff category and university type) on dimensions and overall deviance among university workers in Southwest, Nigeria.

Methods: The study adopted a cross-sectional survey design and a sample size of 384 university workers whose ages range from 22 to 63 years with a mean of 46.88 (SD=9.36) were conveniently selected from four universities. Data were sourced through the Workplace Deviant Behaviour scale and selected demographics which was analyzed using t-test for independent samples.

Results: The results found that there was no gender difference in workplace deviance among university staff [t(382)=-0.37, p>.05]. The study also found that academic workers have a higher tendency to engage in workplace deviance than their non-academic counterparts [t(382)=2.38, p<.05]. Finally, workers from private institutions reported significantly higher workplace deviance than workers from public universities [t(382)= -2.20, p<.05].

Discussion: We can deduce from the study that gender did not have any influence on work deviance as reported by previous study. Also academic staff has higher work deviance than non-academic staff which could be as a result of academic autonomy. Also, staff from private university has higher work deviance than public university which could be as result of the poor job security of private university in Nigeria.

Limitations: One limitation of the study is that some respondents might fake their responses and not disclose their true feeling about the subject matter.

Conclusion: Based on these findings, we concluded that there was no gender difference on work deviance, also there was staff category difference on work deviance and finally, employee from private universities exhibited higher work deviance than their counterpart from public universities.
Share of road transport in greenhouse gas emissions in Poland in 1988–2015

Published: May 2021

The results of an analysis of the greenhouse gas (GHG) emission inventory in Poland in the years 1988–2015 are presented, paying special attention to the impact of road transport on the intensification of greenhouse effect. The analysis was made based on the official results compiled by the National Centre for Emissions Management and Balancing (KOBiZE) at the Institute of Environmental Protection – National Research Institute.

It was found that carbon dioxide emission represented the dominant part of the total GHG emissions, despite that there were other gases having far greater greenhouse effect potential. There was a general downward trend for the national annual emission of basic GHGs. The estimated share of road transport in the GHGs emission was not high: from 4% in 1988 to around 12% in 2015.

For motor vehicles, there is a dominant share in the GHGs emissions of passenger cars: (50 ÷ 60)%.

In the years 1988–2015, there was a relative decrease by about 32% in the national annual emission of carbon dioxide equivalent from all sources covered by the inventory. That notwithstanding, the national annual emission of carbon dioxide equivalent arising from transportation increased generally by about 93% and that from the road transport increased by as much as 117%. The increase in GHGs emissions from motor vehicles resulted mainly from a significant growth in car numbers. Technical progress in the construction of motor vehicles can be evaluated by considering the average annual emission of carbon dioxide equivalent from a conventional car, which has been decreasing since 1998.

Authors: Konieczyński Paweł , Moszczyński Jan , Wesołowski Marek
Published: May 2021

The aim of the investigation was to assess the utility of spruce needles as a potential material to be used for monitoring the contamination level of the environment of Tricity agglomeration (represented by Gdansk and Gdynia). This aim was realized by determining the levels of selected essential elements indispensable for the life of living organisms, such as Fe, Zn, Mn and Cu, as well as toxic, namely Cd and Pb, in spruce needles collected in the locations in Gdynia and for comparison, in Gdańsk. Due to this, the collected samples of needles were dried, and next digested by microwave technique in order to prepare them for quantitative analysis by atomic absorption spectrometry. Moreover, the same metallic elements were determined in the soil samples collected under the spruces, from which needles were taken for the investigation. The concentrations of the studied elements were found in the range of mg/kg of dry mass in the following order: Fe, Mn, Zn, Pb, Cu and Cd (needles), and Fe, Mn, Cu, Zn, Pb and Cd (soils). By application of statistical methods (correlation, variance and principal component analyses), the differences in the elemental composition of spruce needles were identified, as well as sources of this differentiation.

Published: May 2021

In Poland and most of the areas of Europe, the beech, that is, Fagus sylvatica L. is one of the most vital species found in the species composition of forests. A number of the species of foliophages tend to develop on the leaves, which may contribute to the dieback of the tree. The demonstrated results are the effects of the research conducted in 2018 in the Cisów-Orłowiny Landscape Park. Subsequently, 11 species of foliophages were initially discovered there. Such species were inclined to form galls and the miner damages to the beech leaves. Among 4,000 of the analysed leaves, 398 galls and 498 leaf miner damages were found. They were caused by the representatives of insects and mites.

Cilj ovog rada jeste da se pokaže koliko otpada od hrane generišu klasični restorani u Novom Sadu, kakvog je sastava otpad od hrane, koliko doprinosi zagađenju životne sredine preko emisija gasova staklene bašte, i na koji način taj otpad može da se tretira kako bi se smanjila emisija navedenih gasova. U radu su prikazani rezultati dobijeni pomoću programa SWEET, tabelarno i grafički. Razlog za smanjenje otpada od hrane nije samo direktan gubitak hrane, već i efekti na životnu sredinu i ekonomiju, samim tim i na celokupno društvo. Otpad od hrane trenutno prouzrokuje 8% emisije gasova sa efektom staklene bašte, što govori da je smanjenje količina ovog otpada neophodno i zbog klimatskih promena.

Accelerating the transition to post-print processes needed in the printing industry and shortening the time the product's release time is closely related to the drying time of the ink film. The drying of fluid ink on the surface of the print substrate, transforming from liquid to solid occurs physically and chemically in several ways. Drying systems can be functional alone on the surface of the printing substrate for an ink film or depending on the chemical content of the ink and the properties of the printing substrate, drying can be achieved at the same time with more than one system.Recently, in order to reduce climate, environmental and health impacts and with the development of technology, significant changes are also being experienced in the printing industry and preferences are changing. In this study, more environmentally friendly LED UV and microwave drying systems that save time and energy together with existing basic drying systems such as absorption, evaporation, oxidation-polymerization and conventional UV used in the printing industry are examined. The advantages of different drying systems to the printing industry, preferred drying systems and new studies on this issue have been evaluated.

Authors: Kale İbrahim , Helvacıoğlu Çağlar , Muğurtay Tuğba Erel
Published: May 2021

Objective. Investigation of the relationship between the first trimester complete blood count parameters and miscarriage. Materials and Methods. The study group consisted of 39 patients who admitted to the hospital with the diagnosis of abortus imminens between January 2016 and December 2019, and whose pregnancy ended as miscarriage before the 20th week. The control group consisted of 200 randomly selected healthy pregnant women, with follow-up and delivery in our hospital. Patient information was obtained retrospectively from the hospital records. Results. Age and BMI of both groups were similar. There was no significant difference between the two groups in terms of basophil, neutrophil, eosinophil, lymphocyte, monocyte, platelets, RBC, hemoglobin, hematocrit, MCV, MCH, MCHC, RDW, MPV, Pct and PDW, while leukocyte and neutrophil counts was statistically significantly higher in the miscarriage group (p=0,002, p=0,001, respectively). NLR was statistically higher in the miscarriage group (p=0,005), PLR was also higher in the miscarriage group, but this did not reach statistical significance (p=0,056). Both groups were similar in terms of MLR. Conclusions. High NLR levels obtained from the hemogram results in the first trimester seems to be associated with miscarriage. NLR can be an easy, cheap and useful tool for predicting pregnancy prognosis in patients with abortus imminens.
Psychodermatology – a case for sensitization of pharmacists in Mumbai, India
Authors: Malkani Ram H. , Parekh Komal , Karmakar Suman , Setia Maninder Singh
Published: May 2021

Background:

Though studies have looked at the attitudes of dermatologists towards psychodermatology, few have highlighted the attitudes of pharmacists towards these conditions.

Objectives:

To study the knowledge, attitudes and practices of pharmacists towards the prescription of psychotropic medications to dermatology patients.

Methods:

This cross-sectional analysis included 80 pharmacists from Mumbai, India. We used an interviewer-administered questionnaire to collect information from pharmacists on their demographics, psychotropic medications in dermatological patients, knowledge about psychocutaneous conditions and comfort about dispensing these medications.

Results:

In our study, 37 (46%) of pharmacists received prescriptions of psychotropic drugs from dermatologists; however, 24 (30%) were not comfortable dispensing them. Sixty (75%) pharmacists felt that only psychiatrists should prescribe psychotropic drugs and 37 (46%) felt that they had a right to refuse to dispense prescribed medication; of these, 15 (19%) had actually refused to give medications to patients. Pharmacists who disagreed with the statement that 'the state of mind is associated with medical conditions', were more likely to discourage psychotropic prescription from dermatologists (29% vs 11%, P = 0.04). Pharmacists with experience of more than five years were significantly more likely to refuse to dispense medications (odds ratio: 5.14, 95% confidence interval: 1.02, 25.83; P = 0.047).

Limitations:

We did not have a list of all pharmacists in Mumbai; thus, no sampling frame could be applied.

Conclusion:

Pharmacists do comment on doctors’ prescriptions, discourage certain medications and even refuse to dispense them based on their personal opinions. Since they are the last stop for patients between the doctor and the medication, their inclusion (in addition to dermatologists, psychiatrists and psychologists) in integrated awareness, training and care programs would improve the quality of care of patients with psychocutaneous disorders.

Authors: López López Laura Beatriz , Moles Herbera Jesús Adrián , Vázquez Sufuentes Silvia , Fustero de Miguel David , Avedillo Ruidíaz Amanda , Orduna Martínez Javier , Pellejero Juan Casado
Published: May 2021

Background:

Lesions in the temporomesial region can be reached by various approaches: subtemporal, transsylvian, transcortical, interhemispheric parieto-occipital, or supracerebellar transtentorial (SCTT). The choice varies according to the characteristics of the lesion and neighboring structures.

Case Description:

In this clinical case, it is presented a 56-year-old man with long-term evolution of drug-resistant epilepsy secondary to a cavernoma in the left parahippocampal gyrus. After assessing the lesion, it was decided a SCTT approach for its resection in a semi-sitting position, to avoid language disorders or visual damage. The surgery was uneventful and the patient did not present epileptic seizures during 6-month follow-up.

Conclusion:

Performing a SCTT is safe and feasible option for resection of lesions located in the basal temporomesial region without causing damage to neighboring structures, especially those located in the middle and posterior two-thirds of temporal region.

Published: May 2021

Background:

Redundant nerve roots (RNRs) are defined as elongated, thickened, and tortious appearing roots of the cauda equina secondary to lumbar spinal canal stenosis (LSCS). The study compared the clinical and radiological features of patients with LSCS with versus without RNR.

Methods:

This retrospective study was performed on 55 patients who underwent decompressive surgery for degenerative LSCS. Patients were divided into two groups based on the presence of RNR in their preoperative magnetic resonance imaging, as evaluated by a radiologist blinded to the study design. Medical records were reviewed for basic demographic, clinical MR presentation, and outcomes utilizing Japanese Orthopaedic Association (JOA) scores.

Results:

The mean age of enrolled patients was 57.1, with mean follow-up of 4.0 months. RNR was found in 22 (40%) of patients with LSCS. These patients were older than those patients without RNR (62.2 vs. 53.7). Interestingly, there were no statistically significant differences in clinical presentations, duration of symptoms, and outcomes using JOA scores between the two groups.

Conclusion:

RNR is a relatively common radiological finding (i.e., 40%) in patients with LSCS. It is more likely to be observed in older patients. However, no significant differences were noted in clinical presentation and functional outcomes with respect to the presence or absence of RNR.

Chemical Tuning of NaSICON Surfaces for Fast-Charging Na Metal Solid-State Batteries
Authors: Querel Edouard , Seymour Ieuan , Cavallaro Andrea , Ma Qianli , Tietz Frank , Aguadero Ainara
Published: May 2021

Solid-state batteries (SSBs) with alkali metal anodes hold great promise as energetically dense and safe alternatives to conventional Li-ion cells. Whilst, in principle, SSBs have the additional advantage of offering virtually unlimited plating current densities, fast charges have so far only been achieved through sophisticated interface engineering strategies. Here, we reveal that such interface engineering can be easily achieved by tuning the chemistry of NaSICON solid electrolytes (Na3.4Zr2Si2.4P0.6O12) and taking advantage of the thermodynamic stabilization of a Na3PO4 layer on their surface upon thermal activation. The optimized planar Na|NZSP interfaces are characterized by their exceptionally low interface resistances (down to 0.1 Ω cm2 at room temperature) and, more importantly, by their tolerance to large plating current densities (up to 10 mA cm-2) even for extended cycling periods of 30 minutes (corresponding to an areal capacity 5 mAh cm-2).
The Role of Oxygenic Groups and Sp3 Carbon Hybridization in Activated Graphite Electrodes for Vanadium Redox Flow Batteries
Authors: Hassan Ali , Haile Asnake Sahele , Tzedakis Theodore , Hansen Heine Anton , de Silva Piotr
Published: May 2021

Graphite felt is a widely used electrode material for vanadium redox flow batteries. Electrode activation leads to the functionalization of the graphite surface with epoxy, OH, C=O, and COOH oxygenic groups and changes the carbon surface morphology and electronic structure; thus, improving the electrode’s electroactivity relative to the untreated graphite. In this study, we conduct density functional theory (DFT) calculations to evaluate functionalization’s role towards the positive half-cell reaction of the vanadium redox flow battery. The DFT calculations show that oxygenic groups improve the graphite felt’s affinity towards the VO2+/VO2+ redox couple in the following order: C=O > COOH > OH > basal plane. Projected density of states (PDOS) calculations show that these groups increase the electrode’s sp3 hybridization in the same order. We conclude that the increase in the sp3 hybridization is responsible for the improved electroactivity, while the oxygenic groups’ presence is responsible for this sp3 increment. These insights can help in the better selection of activation processes and optimization of their parameters.

Whereas considerable advances have recently been achieved in radical-involved catalytic asymmetric C-N bond formation, there has been little progress in the corresponding C-O bond-forming processes. Here we describe a photoinduced copper-catalyzed cross-coupling of readily oxime esters and 1,3-dienes to generate diversely substituted allylic esters with high regio- and enantioselectivity (>75 examples; up to 95% ee). The reaction proceeds at room temperature under excitation by purple light-emitting diodes and features the use of a single, earth-abundant copper-based chiral catalyst as both the photoredox catalyst for radical generation and the source of asymmetric induction in C-O coupling. Combined experimental and DFT computational studies suggest the formation of π-allylcopper complex from redox-active oxime esters as bifunctional reagents and 1,3-dienes through a radical-polar crossover process.
Chirality-Matched Catalyst-Controlled Macrocyclization Reactions

Published: May 2021

Macrocycles, formally defined as compounds that contain a ring with 12 or more atoms, continueto attract great interest due to their important applications in physical, pharmacological andenvironmental sciences. In syntheses of macrocyclic compounds, promoting intramolecular overintermolecular reactions in the ring-closing step, is often a key challenge. Furthermore, synthesesof macrocycles with stereogenic elements confer an additional challenge, while access to suchmacrocycles are of great interest. Herein, we report the remarkable effect peptide-based catalystscan have in promoting efficient macrocyclization reactions. We show that the chirality of thecatalyst is essential for promoting favorable, matched transition state relationships that favormacrocyclization of substrates with pre-existing stereogenic elements; curiously, the chirality ofthe catalyst is essential for successful reactions, even though no new stereogenic elements arecreated. Control experiments involving either achiral variants of the catalyst, or the enantiomericform of the catalyst, fail to deliver the macrocycles in significant quantity in head-to-headcomparisons. The generality of the phenomenon, demonstrated here with a number of substrates,stimulates analogies to enzymatic catalysts that produce naturally occurring macrocycles,presumably through related, catalyst-defined outer-sphere interactions with their acyclic substrates.

Pseudomonas aeruginosa is the second-leading cause of nosocomial infections and pneumonia in hospitals. Because of its extraordinary capacity for developing resistance to antibiotics, treating infections by Pseudomonas is becoming a challenge, lengthening hospital stays, and increasing medical costs and mortality. The outer membrane protein OprF is a well-conserved and immunogenic porin playing an important role in quorum sensing and in biofilm formation. Here, we used a bacterial cell-free expression system to reconstitute OprF under its native forms in liposomes and we demonstrated that the resulting OprF proteoliposomes can be used as a fully functional recombinant vaccine against P. aeruginosa. Remarkably, we showed that our system promotes the folding of OprF into its active open oligomerized state as well as the formation of mega-pores. Our approach thus represents an easy and efficient way for producing bacterial membrane antigens exposing native epitopes for vaccine purposes.

Any efforts to conduct a sustainable management of urban and natural landscapes benefit from an interdisciplinary approach and active collaboration between actors, thus increasing the feasibility and effectiveness of the proposed actions. With the emergent transition of urban lighting to white LED technology, such shifts can bring a variety of negative effects to these environments, thus such actions should be applied taking into account as broad a knowledge set as available. These are often fragmented and incoherent thus in need of actions which unite them into usable and common tools. In the North Atlantic region of Macaronesia, a project has been implemented which uses the negative effects light pollution has on seabird populations as a base to effect changes in the regional lighting schemes, decreasing light pollution and increasing the sustainability of the current LED transition, improving practices and awareness, to the benefit of both seabirds and human populations alike.

Published: May 2021

Roselle flowers are usually consumed in the form of fresh steeping. To increase the
flexibility of using roselle, effervescent roselle-based products are made which of course
more practical, efficient and attractive. Unfortunately, the bioactive compound in roselle
extracts is not stable to environmental influences so nanoencapsulation technology needs
to be done. The encapsulation matrix type gives a unique effect on each core. The
purposes of this study were to determine the effects of variation in the matrix types and
percentage of roselle nanocapsules on the physical and chemical effervescent properties.
The research design used in this study was a Complete Random Design with 2 factors and
3 replications. The first factor comprised matrix types (A): maltodextrin (A1) and Arabic
gum (A2). The second factor was roselle nanocapsule percentages (B): 10% (B1), 15%
(B2) and 20% (B3). Observed variables in this study were total phenol, anthocyanin,
vitamin C, antioxidant activity and dissolving time. The Arabic gum nano encapsulated
matrix type gave a better value of Vitamin C, antioxidant activity and dissolving time than
maltodextrin, namely 0.149±0.049 µg/3 g, 34.02±4.52%, 2.93±0.80 mins. The percentage
of roselle nanocapsules by 20% gave the highest vitamin C value, namely 0.188±0.032
µg /3 g. The best treatment combination was obtained from the treatment (A2B3) Arabic
gum nanocapsules using the third percentage (20%) with the characteristics: total phenol
content 4.17 µg /3 g, anthocyanin 0.070 µg /3 g, vitamin C 0.188 µg /3 g when it dissolves
in 1.25 mins.

Published: May 2021

Pumpkin antioxidants have been found to benefit diabetics. This current study was
attempted to optimize slow freezing treatment for a pumpkin to obtain maximum
antioxidant gain using response surface methodology (RSM) and Bayesian regularized
neural network (BRANN) approaches. A central composite design was used to generate
the freezing experiment and to examine response change as a function of temperature and
freezing time. Feedforward neural networks with a 2-15-1 structure were developed and
trained using the Bayesian regularization algorithm. The results showed that the freezing
data were well fitted to quadratic models generating R2
for total phenolic compounds
(TPC), flavonoid of 0.850 and 0.857 respectively. The RSM optimized freezing of -20oC
for 9 hrs were well confirmed to produce an increase in TPC and flavonoid by 54.44% and
60.4% respectively. The BRANN performances were found to be similar to that of RSM.
While overfitting was mitigated during the supervised training, the BRANN model served
excellent predictive and confirmatory tool for the optimization. In conclusion, slow
freezing at -20oC for 9 hrs significantly increases TPC and flavonoid of pumpkin. This
novel process may be adopted to provide healthier pumpkins food products for targeted
consumers.
From closed to open. Democratising medical devices using additive manufacture and open source development and distribution systems.
Authors:   , Allen Callum
Published: May 2021

Pupils can provide important neurological information that can aid in the diagnosis of a range of conditions, including aneurysms, impending strokes and tumors in the lung (Gale, et al). In a research context, there is increasing interest in studying the intrinsically photosensitive Retinal Ganglion cells (ipRGC), which respond to intense blue light thanks to a photo pigment called melanopsin. Studying these cells could lead to a better understanding of sleep disorders and a range of optic nerve diseases. Although commercially available pupil testing devices do exist, all cost upwards of $10,000, and suffer from either poor portability or limitations in the tests they can perform. Specifically, the ipRGC require a specific intensity of blue light to be activated and measured, which most devices cannot produce.

In recent years, the open source movement has enabled users from around the world to freely collaborate on the development and distribution of their own products. At first, only software could be produced using this approach, however the continued improvement of 3D printing technology has enabled the same model to be applied to physical products as well. From a medical perspective, this is particularly exciting.

The aim of this research was to produce an inexpensive, open source pupilometer that runs on widely available components, can be distributed online and manufactured using 3D printing technology. In doing so, this thesis asks the question; How can an open source development and distribution model be used in conjunction with online 3D printing services and widely available parts and components to produce an inexpensive and open source pupilometer?

To answer this, a range of practice based methodologies, including research for design and research through design were used to explore this new potential. The resulting design proposal demonstrates how online file sharing platforms, in conjunction with distributed 3D printing services and online supply chains can be combined to develop new medical devices. The ability to collect pupil data using an open source pupilometer may lead to expanded data collection and diagnostic capabilities from doctors in a number of clinical settings, while a cloud based data collection system taking the form of a smartphone app will create a large biometric database and cooperative online research community.

Multivariate statistical analysis application to determine factors affecting the parcel value to be used mass real estate valuation approaches
Authors: YALPIR Şükran , BÜNYAN ÜNEL Fatma
Published: May 2021

Real estate is a form of immovable asset that enables individuals to exert their property rights and provides a form of material guarantee through its economic value. The economic value of real estate, which is reflected in the price, is an aspect that all countries emphasize today by identifying purchase and sale values in market conditions that are removed from large project rumors and speculations. The more the real estate market value is removed from reality, the more negative its effect will be on the cost-benefit of real estate management. This study aimed to identify the main criteria that affect parcel value, which constitutes a basis for real estate, narrow them down to the optimum level using questionnaires and standardize them. A total of 559 experts working in real estate valuation and 1,915 members of the public that play a role in real estate purchases and sales were contacted in Ankara, Konya and Kayseri, all of which are located in the Central Anatolia Region of Turkey. The factor analysis method was applied to the survey data. Grouping was carried out with 10 factors and the results were interpreted.
