Startup
Authors: Temur Gül Tekin , Yoşlı Fatma , Bolat Bersam
Published: May 2022

Introduction:

Tech startups are fast-growing businesses that target the demands of the
marketplace by developing innovative products, services, or platforms. Startups ensure socially,
economically, or environmentally more effective alternatives by using or by creating appropriate
technologies. Many factors have become prominent regarding the success and sustainability of the
product or service offered by the startup: investment, experience, and education of the team, the
leadership of the management, creativity, innovation, technological breakthroughs, surrounding
community, future perspective, target marketing strategy, location and the analysis of the market,
etc. But since 80% of startups do not survive after five years, defining the important risk factors is
crucial to develop the right strategies for successful startups. In this study, the risk factors have
been defined based on the business model, which has an important place in the success of the technology
startups, which use technology intensively. Comprehensive risk analysis on identified factors
is presented to identify effective managerial strategies for technology startups to not fail.

Methods:

Spherical Fuzzy Failure Mode and Impact Analysis (SFFMEA) was used within the
framework of a business model canvas for risk analysis for the failure of technology startup projects.
Due to the lack of recorded data for analysis, the opinions of field experts were used. While
the business model canvas guided the identification of detailed risk factors, FMEA enabled the risk
analysis of factors that cause startup projects to fail, and considering parameters related to the
probability of the relevant risk factors, their impact on the failure of the project, and the detection
level of the risk factor. Spherical Fuzzy, on the other hand, allowed the quantitative inference of
FMEA's comprehensive parameter definitions associated with the risk factors through experts.
Thus, all risk factors that may cause the failure of tech startups were ranked according to their risk
priority numbers (RPNs), with the SFFMEA analysis, which offers a comprehensive risk analysis.

Results:

The findings show that the most important causes of the tech startup’s failure are “noncompliance
with existing restrictions”, “inappropriate venture capital strategy”, and “lack of clustering
support”.

Conclusion:

These failure modes can be interpreted according to their frequency of encounter, potential
effects, and detectability, and can be considered an important finding in the development of
appropriate managerial strategies for the mitigation of the risk factors so the startups can survive in
their first five years. Also, with the proposed risk analysis methodology, a comprehensive analysis
of any startup project can be performed according to its conditions and characteristics.

Published: May 2022

In this study, nine types of bread wheat (Triticum aestivem L.) were used. To analyze it at the molecular level, Random Amplified Polymorphic D.N.A. (R.A.P.D.) markers based on PCR technology were used to study the variations of the cultivars. It is absent in other varieties and can be used as a distinctive genetic fingerprint to preserve plant breeders' rights. Genetic banks can use it to distinguish the mentioned varieties and models, confirming the importance of this technique in molecular characterization and genetic fingerprinting studies. From the results of the molecular aspect, the similarity matrix was implemented based on the coefficients of (Nei & Lie) for the nine studied varieties.

The highest similarity value was between the variety (Taymoz/2 and Baghdad/3), and its value was 0.9167. Most of the traits showed a similarity in the mean between them for all the genetic traits, but the lowest similar value was between the two varieties (Rashid and Baghdad/1). Genetic level, the cultivar seeds were sown under arid conditions in the fields. The experimental unit contained two lines for each category, the length of the line was 2 m, and the distance between the lines was 30 Cm. The characteristics of the number of days of 50% flowering, plant height (Cm), biological yield (gm/plant), grain yield (gm/plant) and weight of 100 grains (gm) were studied. The inputs differed significantly at the 1% probability level for all studied traits. There was high genetic variance for the characteristics of the biological yield (kg/ha) and seed yield (kg/ha), and the weight of one hundred seeds (g). The highest values of genetic variation coefficients for seed yield were superior. The percentage of heritability in its broad sense was high for all the studied traits. The values of the expected genetic improvement were a high percentage of seed yield, vital yield, harvest index, number of total branches per plant, the average for plant height, first pod height (Cm), number of seeds/pod, the weight of 100 seeds, and few numbers of days to flowering at 50%.

Authors: Furman Gregory , Furman Evgeny , Charushin Artem , Eirikh Ekaterina , Malinin Sergey , Sheludko Valery , Sokolovsky Vladimir , Shtivelman David
Published: May 2022

Background

Respiratory sounds have been recognized as a possible indicator of behavior and health. Computer analysis of these sounds can indicate characteristic sound changes caused by COVID-19 and can be used for diagnostics of this illness.

Objective

The aim of the study is to develop 2 fast, remote computer-assisted diagnostic methods for specific acoustic phenomena associated with COVID-19 based on analysis of respiratory sounds.

Methods

Fast Fourier transform (FFT) was applied for computer analysis of respiratory sound recordings produced by hospital doctors near the mouths of 14 patients with COVID-19 (aged 18-80 years) and 17 healthy volunteers (aged 5-48 years). Recordings for 30 patients and 26 healthy persons (aged 11-67 years, 34, 60%, women), who agreed to be tested at home, were made by the individuals themselves using a mobile telephone; the records were passed for analysis using WhatsApp. For hospitalized patients, the illness was diagnosed using a set of medical methods; for outpatients, polymerase chain reaction (PCR) was used. The sampling rate of the recordings was from 44 to 96 kHz. Unlike usual computer-assisted diagnostic methods for illnesses based on respiratory sound analysis, we proposed to test the high-frequency part of the FFT spectrum (2000-6000 Hz).

Results

Comparing the FFT spectra of the respiratory sounds of patients and volunteers, we developed 2 computer-assisted methods of COVID-19 diagnostics and determined numerical healthy-ill criteria. These criteria were independent of gender and age of the tested person.

Conclusions

The 2 proposed computer-assisted diagnostic methods, based on the analysis of the respiratory sound FFT spectra of patients and volunteers, allow one to automatically diagnose specific acoustic phenomena associated with COVID-19 with sufficiently high diagnostic values. These methods can be applied to develop noninvasive screening self-testing kits for COVID-19.

Published: May 2022

Objective: The objective of the current investigation was to design aceclofenac encapsulated microbeads using gellan gum and linseed gum blends following ionotropic gelation by trivalent Al3+-ions as cross-linking agent.
Methods: Various formulation parameters like polymer-polymer blend (gellan gum and linseed gum), proportion and concentration of aluminium chloride (i.e., cross-linker) were considered for preparation of different formulations. In vitro aceclofenac release from these microbeads was performed in 0.1 N HCl (pH 1.2) for a preliminary 2 h, and after this period, it was continued in phosphate buffer (pH 7.4) for the next 6 h (a total of 8 h).
Results: These gellan gum-linseed gum microbeads of aceclofenac exhibited drug encapsulation efficiency of 27.70 ± 0.42 to 74.27±2.57 % and average sizes of gellan gum-linseed gum microbeads were ranged 739.57 ± 22.70 to 968.07 ± 42.24 µm. The release of drug (in vitro) from these gellan gum-linseed gum microbeads of aceclofenac demonstrated a sustained pattern of drug-releasing (over 8 h).
Conclusion: These gellan gum-linseed gum microbeads can be used as an effectual option of polymeric carrier matrices for sustained release.

Objective: The present study aims to investigate the effect of using DMSO as an enhancer on the ex vivo penetration of an emulgel from sesewanua leaf extracts.
Methods: The sesewanua emulgel was prepared into four formulas, SWE1-SWE4, with different DMSO concentrations: 0%, 3%, 5%, 7%, and compared with QCE, quercetin without DMSO. Further, the penetration test of the sesewanua leaf ethanol extract emulgel was performed by determining the rate and cumulative penetration of quercetin within the skin of the mice by employing the Franz diffusion cell approach.
Results: The SWE4 emulgel containing 7% of DMSO was the best formula that enhanced the penetration of the emulgel, with a cumulative penetration at 331.423 mg/cm2, the penetration rate at 2.762 µg/cm2/minute, and better dispersibility of 4.6 cm and the results of the one-way ANOVA suggested a significant influence (p<0.05). DMSO with a concentration of 7% of the sesewanua emulgel was proven to increase 2,4-fold the rate and cumulative amount penetration. DMSO can be considered as a penetration enhancer of natural compounds for anti-inflammatory treatment.
Conclusion: The use of natural ingredients as topical anti-inflammatory continues to be developed to avoid the first-pass effects. The used of DMSO in topical emulgel preparation become a simple way to enhance the penetrant of active inggredient.
A SYSTEMATIC REVIEW ON SUPERSATURABLE SELF-NANO EMULSIFYING DRUG DELIVERY SYSTEM: A POTENTIAL STRATEGY FOR DRUGS WITH POOR ORAL BIOAVAILABILITY
Authors: REDDY MUTHADI RADHIKA , GUBBIYAPPA KUMAR SHIVA
Published: May 2022

The most fundamental important extensive constitutive of drug molecules to be available for systemic absorption is aqueous solubility; subsequently, that is the nature of GIT fluid. When the drug molecules become solubilized, it has to reach the systemic circulation via the biological membrane. The solubility problem of many effective pharmaceutical molecules is still one of the major challenges in the formulation of this molecule. Drug molecules that belong to class II have a problem in bioavailability mainly due to low aqueous solubility and the rate-limiting step is the dissolution process and so electing of suitable drug delivery and proper additives are decisive to overcome this major obstruction and promote the fraction that will reach the systemic circulation. Among the different lipid-based systems, the su-SNEDDSs have gained attention because the inclusion of precipitation inhibitors within su-SNEDDSs helps maintain drug supersaturation after dispersion and digestion in the gastrointestinal tract. This enhances the bioavailability of drugs and minimizes the variability of exposure. Nowadays, supersaturable self-nano emulsifying and nano lipid-based drug delivery systems have constrained a substantial concern from pharmaceutical scientists for managing the oral delivery of poorly water-soluble compounds. By following oral administration, self-nano emulsifying drug delivery systems show complex aqueous dispersion and digestion in the GIT and enduring intestinal lymphatic transport, exorbitant pre-absorptive metabolism by gut membrane-bound cytochrome enzymes and preventing P-gp mediated drug efflux.
Mostly these processes result in drug supersaturation, which leads to increased absorption or the high drug concentrations may cause precipitation with capricious and variable oral bioavailability. This procession review briefly summarized drug supersaturation obtained from self-nano emulsifying and other lipid-based formulations and this review also delineate the effects of numerous physiological factors and the probable interactions between PIs and lipid, lipase or lipid digested products on the in vivo performance of su-SNEDDS and focuses on reviewing the application of su-SNEDDS in enhancing the solubility and bioavailability of anti-cancer drugs in cancer therapy.

Phenotypic expression of dairy influence often carries negative implications in beef production; thus, considerable variation in expression of beef- versus dairy-type might adversely affect value of crossbred beef × dairy cattle. This study evaluated effects of phenotype in crossbred beef × dairy cattle, specifically that associated with beef- versus dairy-type, on meat quality. Effects were blocked within commercial feedlot pens because cattle within a pen were contemporaries for sex, age, management, and source. On their harvest date, 592 Angus or [Simmental × Angus] × Holstein cattle from 9 pens were assessed by 3 expert evaluators. Scores for muscling and frame size were used to categorize and subset cattle in a pen into 4 phenotype groups: (1) fully dairy-type, (2) partially dairy-type, (3) partially beef-type, and (4) fully beef-type. Strip loin steaks were obtained from selected cattle (n = 82 to 84 per group) and evaluated for descriptive sensory attributes, shear force, pH, color at retail display, steak dimensions, muscle fiber type, and fatty acid composition. Data were tested for fixed effects of phenotype group with random effects of pen. Despite distinct expression of visual beef- versus dairy-type among cattle sampled, phenotype groups were largely not different (P > 0.05) in shape, sensory attributes, color, or biochemical properties of strip loin steaks. Other body regions, separate from the loin, were likely responsible for differences in live animal muscling. Additional research is needed on effects of sire breed, individual sire, and management strategies on meat quality in beef × dairy crossbreds. Complementarity of beef breeds and sires to produce more profitable beef-type cattle from the beef × dairy mating system should not be expected to negatively influence meat quality. Marketing programs rooted in production of consistent and premium products may benefit from including beef from beef × dairy crossbreds.

Published: May 2022

Abstract: Current state of emotion of a person is highly related to what entertainment content he/she want to listen or watch. An emotion-based content recommendation will help the user to not only to get content according to their current state of mind but also reduce the efforts of managing a playlist for music and help them reduce their stress level by recommending them appropriate content for stress relief. Emotion of a person can be determined using his/her facial expression. This facial expression can be detected using a machine learning model, we have developed a model using xception architecture. An application which will access the camera of the device and take image of the persons face, it will connect to the ML Kit stored on the cloud (Firebase) which will analyze the image and detect the mood of the user, from that mood it will connect to API of a music and movies application (E.g., Spotify, Netflix, Disney Hotstar, etc.), though which we will recommend the content. The application will also verify from the user for his/her taste of music and customize the recommendation accordingly. The user will be prompted for change in emotion after specific intervals if he/she likes to change the content.

Abstract: Recommender system are systems which provide you with a similar type of products or solutions and results, you are looking for. For example, if you go to a Clothing shop, you ask for a T-shirt with different designs or different colors, Then the shopkeeper recommends you with different colors. This recommending task for websites is done by recommending systems. A recommendation engine uses several algorithms to filter data and then recommends the most relevant items to consumers. A Movie Recommender system will recommend the most relevant and connected movie for the given category of search, if a user visits a movie site for the first time, the site will have no previous history of that user. In such cases, the user can search for their movie recommendations based on genre, year of release, director or actor and their favorite movie itself to get a new movie recommendation.

CRIANDO TERRITÓRIOS EM RESISTÊNCIA: PERIFERIAS URBANAS, ECONOMIAS DIVERSAS E O PAPEL SOCIOECONÔMICO DE CRECHES E CRECHEIRAS EM SANTA LUZIA, DISTRITO FEDERAL
Authors: Husseini de Araújo Shadia , Taveira Rudy Júlia
Published: May 2022

Neste artigo, defendemos a tese de que creches informais em periferias urbanas não ocupam meramente o espaço vazio deixado pela ausência do serviço público. Para além disso, creches e crecheiras podem desempenhar um papel fundamental na criação do que Raúl Zibechi chama de “territórios em resistência”. Ilustramos essa tese por meio de uma pesquisa sobre as creches localizadas no Setor de Chácaras Santa Luzia, no Distrito Federal. A análise desse estudo de caso fundamenta-se sobretudo nos conceitos de “territórios em resistência” (ZIBECHI, 2015) e de “economias diversas” (GIBSON-GRAHAM, 1998), nas repercussões desses conceitos em debates mais recentes sobre a periferia urbana, bem como no método etnográfico. Os resultados da pesquisa mostram que as crecheiras de Santa Luzia contribuem, por meio de seus projetos socioeconômicos, para a resistência contra os ataques causados pela expansão capitalista, ao mesmo tempo em que viabilizam a vida cotidiana na periferia urbana. Esses projetos baseiam-se majoritariamente em uma lógica familiar-comunitária centrada na figura da “mulher-mãe”. Desse modo, procuramos contribuir, neste artigo, com os debates acadêmicos que refletem sobre a criação e o funcionamento de “territórios em resistência”, bem como sobre as relações de gênero neles envolvidas. Adicionalmente, pretende-se também ampliar o debate sobre o papel social de creches informais em periferias urbanas.

O VETOR TERRITORIAL E O VETOR RETICULAR DA SEGURANÇA INTERNACIONAL
Authors: Monteiro Licio Caetano do Rego
Published: May 2022

O presente artigo busca pensar a segurança internacional em termos geográficos, discutindo a dimensão espacial da segurança, geralmente negligenciada nos estudos realizados pelas disciplinas que tradicionalmente se aprofundam no assunto. São dois enfoques para explorar a dimensão geográfica da segurança: territórios (e fronteiras) e redes (e fluxos), traduzidos como vetor territorial e vetor reticular. O vetor territorial é o enfoque da segurança a partir da territorialidade estatal em suas expressões mais imediatas, o território e a fronteira. O vetor reticular, em contraposição ao primeiro, explora os dispositivos não-territoriais, relacionados à circulação, às redes e aos fluxos que cruzam as fronteiras.

Published: May 2022

Sluggish hydrate kinetics and low methane storage capacity give rise to
the limitation of the application of hydrate-based solidified natural
gas (SNG) technology. Here, we prepared two nano-promoters of -SO3-@PSNS
and -COO-@PSNS, with which, methane hydrate formation in a
spiral-agitated reactor under mild conditions was evaluated. Excitingly,
spiral agitation enhances hydrate nucleation and initial growth
kinetics, while the nano-promoters improve hydrate later growth
kinetics, and the synergy of them results in extraordinary hydrate
formation kinetic under mild conditions. Large methane storage
capacities of 147.28 V/V and 141.33 V/V were obtained in the systems of
-SO3-@PSNS and -COO-@PSNS separately under the condition of 3.8 MPa,
275.15 K and 30 rpm, which increase by 85.07% and 77.59% comparing to
that in pure water, respectively. The synergy performs better than that
of spiral agitation and amino acids, and this may promote the
application of SNG technology a step forward.

ABSTRACT Objective: Recent increased awareness and research studies
reflect possible associations between opioid exposure and cancer
outcomes. Children with neuroblastoma (NB) often require opioid
treatment for pain. However, associations between tumor response to
chemotherapy and opioid exposure have not been investigated in clinical
settings. Methods: This is a single institution retrospective review of
patients with NB treated between 2013 and 2016. We evaluated opioid
consumption quantified in morphine equivalent doses (mg/kg) based on
nurse- or patient-controlled analgesia during antibody infusions. We
also analyzed their associations with change in tumor volume and
extra-adrenal tumor burden. Results: Of 42 patients given opioids for
pain related to anti-GD2 mAb, data completion was achieved for 36 and
details of statistical analyses were entered. Median total weight-based
morphine equivalent (over 8 days) was 4.71 mg/kg (interquartile range
3.49-7.96). We found a statistically insignificant weak negative
relationship between total weight-based morphine equivalents and tumor
volume ratio (correlation coefficient -0.0103, p-value 0.9525) and a
statistically insignificant weak positive relationship between total
weight-based morphine equivalent and Curie score (correlation
coefficient 0.1096, p-value 0.5247). Conclusion: Our study found no
statistically significant correlation between opioid consumption and NK
cell-mediated killing of NB cells as measured by effects on tumor
volume/tumor load.

Background/Aim. The mental health of medical students worsens during their studies, and research shows that medical students are at high risk of depression. The aim of this study was to evaluate the prevalence of depressive symptoms and to examine the association between various risk factors and depressive symptoms in a sample of first- and sixth-year medical students at the University of Novi Sad. Methods. A cross-sectional study was conducted at the Faculty of Medicine of the University of Novi Sad. The sample consisted of 308 students divided into two groups ? 213 students in the first year and 9 5 students in the final (sixth) year of medical studies. The Patient Health Questionnaire-9 (PHQ-9) was used to measure depressive symptoms. Within this instrument, item 9 was used to identify suicidal ideation. Self-esteem was evaluated with the Rosenberg Self-Esteem Scale (RSES). Additional questions were focused on self-assessed material status, lifestyle factors, and mental healthcare-seeking. Univariate and multivariate logistic regression analyses were applied. Results. The prevalence of depressive episodes among medical students was 16.6%. Almost 9% had thoughts of committing suicide. First-year students with low self-esteem were almost seven times more likely to suffer from moderate to severe depressive symptoms than those with high self-esteem. Students who had used sleeping pills or sedatives without a prescription were nearly five times more likely to have a PHQ-9 score ? 10 than those who had not [odds ratio (OR) = 4.97, 95% confidence interval (CI): 1.83?13.52)]. Sixth-year students with poor or average self-assessed social relation-ships and low self-esteem had a stronger association with a PHQ-9 score ? 1 0. Conclusion. There is a high prevalence of depressive episodes among first and sixth-year medical students, and it is associated with low self-esteem in both groups, use of sleeping or sedative pills without a prescription among first-year students, and poor social health in sixth-year students. We recommend routine screening for depression in medical students and establishing prevention and intervention programs.

Trail running, also known as mountain running or simply trail, it’s a running sport consisting in long course running in an uneven terrain usually at high altitude, occasionally in extreme weather conditions, although being sometimes performed in the desert or coastal areas. It’s an extremely high physiological demand sport, especially for the subtalar and tibiotalar joints, which makes these athletes particularly prone to ankle and hindfoot injury. Sinus tarsi syndrome can be defined as pain referred to sinus tarsi region and hindfoot instability, mainly after a traumatic event and with a difficult diagnosis. The authors present a case of sinus tarsi syndrome on an elite trail athlete, making a brief review of the literature.

Este ano, no Casa Pia Atlético Clube, estou a viver uma época de sonho, não só a nível desportivo, mas acima de tudo a nível organizativo. A capacidade do trabalho centrado no atleta, a otimização do rendimento através da avaliação cuidada individual é algo que por norma era muito difícil de alcançar. Todo este trabalho feito nos últimos anos está a dar frutos, com poucas lesões e com rendimento individual e coletivo de excelência. O poder trabalhar com fisioterapeutas, como tenho tido o privilégio, é uma vantagem com que sonho nos Cuidados de Saúde Primários. O Estado pouparia dinheiro se todos os Centros de Saúde tivessem fisioterapeutas que pudessem trabalhar individualmente com os nossos doentes, traria menos absentismo laboral, teria pessoas mais bem-dispostas, pois a dor não estaria presente no dia a dia.

Osgood-Schlatter disease is a traction apophysitis of the anterior tibial tuberosity. It is a selflimiting disease, with resolution in up to 90% of patients with conservative treatment. Its etiology is unknown despite clinical observation of the role of mechanical stress on the knee extensor apparatus in exacerbating symptoms. It occurs more commonly in males, between 10 and 15 years old and in physically active population. Its clinics reveals anterior knee pain with or without oedema, which can be unilateral or bilateral. Its diagnosis is clinical, and the main complementary exam is a radiography with two incidences (face and profile). The treatment is based on pain control, and quantitative and qualitative management of the work loads. Surgery is recommended only in rare cases.
