Encountering the invisible
Authors: Helke Susanna
Published: July 2019

This paper discusses the potential of art-practice-led and research-in-the-arts methodologies, introducing the idea of the theory–praxis–poetics triangle as a process of catalysing new methods, expressions and approaches in filmmaking, especially in the context of documentary cinema. It elaborates upon these approaches in the context of my own filmmaking practice and in relation to the conventions stemming from the tradition of social documentary. What are the methods of making visible the invisible complexities of present-day societal reality, as poverty, exclusion and societal tensions may not be as visually dramatic as they were when the ethos of “social documentary” was defined? How can the invisible and often-abstract core of phenomena such as the neoliberal paradigm shift in post–welfare-state contexts be made visible? Documentary film as a discourse of sobriety mostly relies on the serious and solemn, but can absurdism and parody more accurately capture the core of paradigmatic political phenomena like the current one? The acute global crises create a need for re-evaluating the potential of documentary film practice as a reflexive and critical endeavour beyond the emotion economy of the hegemonic film industries. As the arts function beyond the pre-existing order of commonsensical reality, the pressing question is: how can reality-material–based art construct a transformational ethical address, one which does not rely on individualistically driven social subjectivity but rather creates experiential spaces for agonistic collisions of differences, the paradoxical, dialectical cinematic approaches that can be claimed to be more complex than a mere “emotive” address? In this dangerously polarized era, it is crucial to distinguish between such fluid concepts as the sentimental, emotional or compassionate, in order to rehabilitate the poetics of documentary art in creating a reflexive political address.

Published: July 2019

El siguiente estudio analiza la influencia sobre las propiedades mecánicas y térmicas de los morteros de cemento al adicionar fibras de cabuya negra (Agave Americano). En base a las normas de construcción utilizadas en Ecuador, se determinó la mezcla ideal para la  matriz cementicia, que servirá de referencia al momento de agregar las diferentes concentraciones de fibra de cabuya.Las longitudes consideradas para la fibra fueron 15 mm y la distribución es de tipo aleatoria. Para las diferentes configuraciones de refuerzo se agregaron cuatro fracciones volumétricas nominales de fibra: 0.25; 0.50; 0.75; y 1.0 %. Los especímenes fabricados fueron sometidos a ensayos de conductividad térmica, calor específico, resistencia a flexión y compresión. Los resultados obtenidos mostraron que el mortero  reforzado con una fracción volumétrica de fibra de cabuya de 0.50 % exhibió la fluidez ideal de un material apto para recubrimientos, limitando así la cantidad máxima de fibra que puede agregarse para formar el material. Como resultado se determina que la resistencia a la compresión y a la flexión del material compuesto es mayor con respecto a la matriz cementicia  9 y 11% respectivamente, se determina también que la conductividad térmica y el calor específico  en comparación con la matriz cementicia mejoraron 13 y 18 % respectivamente.

Published: July 2019

Psywar merupakan keadaan yang tercipta dari faktor lingkungan. Jika atlet mengalami hambatan pada faktor ini dikarenakan oleh psywar, Demikian pula yang terjadi dalam cabang olahraga bola basket.Penelitian ini menggunakan treatment by subject, dimana satu kelompok subjek diberi dua perlakuan, pertama dengan menggunakan psywar dan yang kedua tanpa psywar. Kelompok subjek penelitian ialah anggota tim bola basket SMKN 1GRATI yang berjumlah 8 orang.Untuk mengukur tingkat kecemasan, peneliti menggunakan metode angket.Angket diberikan kepada seluruh anggota tim yang bermain segera setelah pertandingan usai. Hal ini disebabkan karena pemberian angket saat pertandingan berjalan hingga paruh babak akan mengganggu konsentrasi pemain, dan hasil angket yang diberikan pemain pada paruh babak pertama belum tentu sama dengan hasil pada paruh babak kedua.Sedangkan untuk mengukur performa atlet, peneliti menggunakan lembar statistik pertandingan resmi yang diberikan oleh Perbasi Namun dalam penelitian ini, aspek yang digunakan two point shots percentage.Dari data yang diperoleh, ternyata peneliti memperoleh kesimpulan bahwa psywar yang diberikan oleh tim lawan kepada tim SMKN 1Grati sebagai subjek penelitian, ternyata tidak secara langsung mempengaruhi tingkat kecemasan dan performa atlet bola basket SMKN 1Grati.

Published: July 2019

A survey of the freshwater fish composition in the upper Baleh River, Sarawak was conducted in 2015. A total of 1,538 specimens, comprising 45 species from nine families were collected using electrofishing devices and cast nets. The family Cyprinidae was the most dominant (62.9%) as well as diverse (42.2%) family, followed by the Balitoridae (31.0%; 31.1%) in the river. The three most dominant species were Tor tambra (18.1%), Lobocheilos ovalis (12.9%), and Parhomaloptera microstoma (11.3%). Shannon’s diversity index, Margalef’s richness index, and Pielou’s evenness index were 2.9, 6.0, and 0.8, respectively, an indication of moderate species diversity. Canonical Correspondence Analysis demonstrate that elevation, stream order and sedimentation were the most significant factors related to fish assemblages in the river, particularly for members of the families Cyprinidae and Balitoridae. The coefficient ‘n’ value in length-weight relationship for T. tambra, L. ovalis, and P. microstoma were determined as 2.92, 2.72, and 3.15, respectively. T. tambra and L. ovalis exhibited a negative allometric growth pattern which could be due to food competition whereas P. microstoma exhibited a positive allometric growth pattern as mountainous forest stream habitat offers favourable environmental conditions. The Fulton’s condition factor of each species indicates that T. tambra and L. ovalis were in poor condition, whereas P. microstoma was in extremely poor condition. It is hypothesized that environmental degradation caused by logging activities have affected the health of the most dominant fish species in the upper Baleh River. Further study should be conducted to determine the underlying factors that are affecting the fish diversity.

Published: July 2019

Palm oil mill effluent (POME) contains a high amount of nutrients and organic matter; therefore, it has been considered as an alternative liquid fertilizer (LF). However, the studies on the reuse of POME as fertilizer have been mostly limited to nutrients absorption but the leachates were neglected. Such approach caused potential impacts on ground water pollution. Thus, this research aimed to compare the leachabilities of ammoniacal nitrogen (NH3-N) and phosphate (PO43-), as well as the growth rates of oil palm seedlings in three different watering conditions. Six oil palm seedlings were watered with either POME, LF or tap water. The leachates from each seedling pot were collected weekly and analyzed for their NH3-N and PO43- concentrations. The pots which were watered with tap water showed the highest leaching rate of 0.0251 mg.L-1.week-1 for NH3-N and 0.0392 mg.L-1.week-1 for PO43-. The average concentrations of NH3-N in the leachates from the POME, LF and tap water potswere 0.45, 0.38 and 0.36 mg/L, respectively, whereas for PO43-, the average concentrations were 1.09 (POME), 0.96 (LF) and 0.66 (tap water) mg/L. The quickest plant growth rates were recorded in tap water (0.56 cm/day), followed by LF (0.51 cm/day) and POME (0.42 cm/day).

A Statistical State Analysis of a Marine Gas Turbine

Published: July 2019

This paper describes the analysis, from a statistical point of view, of a maritime gas turbine, under various operating conditions, so as to determine its state. The data used concerns several functioning parameters of the turbines, such as temperatures and vibrations, environmental data, such as surrounding temperature, and past failures or quasi-failures of the equipment. The determination of the Mean Time Between Failures (MTBF) gives a rough estimate of the state of the turbine, but in this paper we show that it can be greatly improved with graphical and statistical analysis of data measured during operation. We apply the Laplace Test and calculate the gas turbine reliability using that data, to define the gas turbine failure tendency. Using these techniques, we can have a better estimate of the turbine’s state, and design a preventive observation, inspection and intervention plan.
The Function of Lgr5+ Cells in the Gastric Antrum Does Not Require Fzd7 or Myc In Vivo
Authors: Flanagan Dustin , Barker Nick , Ernst Matthias , Vincan Elizabeth , Phesse Toby
Published: July 2019

The extreme chemical and mechanical forces endured by the gastrointestinal tract drive a constant renewal of the epithelial lining. Stem cells of the intestine and stomach, marked by the cell surface receptor Lgr5, preserve the cellular status-quo of their respective tissues through receipt and integration of multiple cues from the surrounding niche. Wnt signalling is a critical niche component for gastrointestinal stem cells and we have previously shown that the Wnt receptor, Frizzled-7 (Fzd7), is required for gastric homeostasis and the function of Lgr5+ intestinal stem cells. Additionally, we have previously shown a requirement for the Wnt target gene Myc in intestinal homeostasis, regeneration and tumourigenesis. However, it is unknown whether Fzd7 or Myc have conserved functions in gastric Lgr5+ stem cells. Here we show that gastric Lgr5+ stem cells do not require Fzd7 or Myc and are able to maintain epithelial homeostasis, highlighting key differences in the way Wnt regulates homeostasis and Lgr5+ stem cells in the stomach compared to the intestinal epithelium. Furthermore, deletion of Myc throughout the epithelium of the gastric antrum has no deleterious effects suggesting therapeutic targeting of Myc in gastric cancer patients will be well tolerated by the surrounding normal tissue.
Spatiotemporal Analysis of Diurnal Temperature Range: Effect of Urbanization, Cloud Cover, Solar Radiation, and Precipitation
Authors: Pyrgou Andri , Santamouris Mattheos , Livada Iro
Published: July 2019

High daily temperatures in the Mediterranean and Europe have been documented in observation and modeling studies. Long-term temperature data, from 1988 to 2017, from a suburban station and an urban station in Nicosia, Cyprus have been analyzed, and the diurnal temperature range (DTR) trend was investigated. The seasonal Mann–Kendall test revealed a decreasing DTR trend of −0.24 °C/decade at the urban station and −0.36 °C/decade at the suburban station, which were attributed to an increase in the daily minimum temperature. Variations in precipitation, longwave radiation, ultraviolet-A (UVA), ultraviolet-B (UVB), cloud cover, water vapor, and urbanization were used to assess their possible relationship with regional DTR. The clustering of daytime and night-time data showed a strong relationship between the DTR and observed cloud cover, net longwave radiation, and precipitation. Clouds associated with smaller shortwave and net longwave radiation reduce the DTR by decreasing the surface solar radiation, while atmospheric absolute humidity denotes an increased daytime surface evaporative cooling and higher absorption of the short and longwave radiation. The intra-cluster variation could be reduced, and the inter-cluster variance increased by the addition of other meteorological parameters and anthropogenic sources that affect DTR in order to develop a quantitative basis for assessing DTR variations.
Illumination Geometry and Flying Height Influence Surface Reflectance and NDVI Derived from Multispectral UAS Imagery
Authors: Stow Daniel , Nichol Caroline , Wade Tom , Assmann Jakob , Simpson Gillian , Helfter Carole
Published: July 2019

Small unmanned aerial systems (UAS) have allowed the mapping of vegetation at very high spatial resolution, but a lack of standardisation has led to uncertainties regarding data quality. For reflectance measurements and vegetation indices (Vis) to be comparable between sites and over time, careful flight planning and robust radiometric calibration procedures are required. Two sources of uncertainty that have received little attention until recently are illumination geometry and the effect of flying height. This study developed methods to quantify and visualise these effects in imagery from the Parrot Sequoia, a UAV-mounted multispectral sensor. Change in illumination geometry over one day (14 May 2018) had visible effects on both individual images and orthomosaics. Average near-infrared (NIR) reflectance and NDVI in regions of interest were slightly lower around solar noon, and the contrast between shadowed and well-illuminated areas increased over the day in all multispectral bands. Per-pixel differences in NDVI maps were spatially variable, and much larger than average differences in some areas. Results relating to flying height were inconclusive, though small increases in NIR reflectance with height were observed over a black sailcloth tarp. These results underline the need to consider illumination geometry when carrying out UAS vegetation surveys.

Published: July 2019

Wild-caught hāpuku (Polyprion oxygeneios) spawn readily in captivity, but although first filial (F1) hāpuku complete vitellogenesis, females fail to undergo oocyte maturation and spawn or produce poor quality eggs. This study investigated whether administration of a synthetic agonist of gonadotropin-releasing hormone (GnRHa) could improve F1 hāpuku spawning and complete the life-cycle in captivity. Spawning trials were conducted over 2 years in 2013 and 2014, when F1 were aged five and six years. In 2013, females previously conditioned under a variable or constant temperature regime were implanted with GnRHa (100 μg/kg−1) or blank implants constructed of powdered cellulose and cholesterol. Spawning was erratic and egg quality very poor in all tanks. No F2 offspring were produced by communal spawning. In contrast, viable F2 larvae were produced by strip-spawning and in vitro fertilization after a series of GnRHa injections. In 2014, two additional trials were conducted: females received ethylene-vinyl acetate copolymer (EVAc) matrix implants containing GnRHa (100 μg/kg−1) or blank implants and in the second trial, two GnRHa doses (100 μg/kg−1 and 50 μg/kg−1) were tested. Eggs were first detected in all tanks 12–17 days post-implantation when females received 100 µg/kg−1 GnRHa implants, but not in the lower dose or control tanks. In summary, this study achieved induction of female spawning with GnRHa implants (target dose 100 μg/kg−1) and the successful production of F2 hāpuku in captivity by strip-spawning.
A New Exact Solution for the Flow of a Fluid through Porous Media for a Variety of Boundary Conditions
Authors: Mahabaleshwar U. , Vinay Kumar P. , Nagaraju K. , Bognár Gabriella , Nayakar S.
Published: July 2019

The viscous fluid flow past a semi-infinite porous solid, which is proportionally sheared at one boundary with the possibility of the fluid slipping according to Navier’s slip or second order slip, is considered here. Such an assumption takes into consideration several of the boundary conditions used in the literature, and is a generalization of them. Upon introducing a similarity transformation, the governing equations for the problem under consideration reduces to a system of nonlinear partial differential equations. Interestingly, we were able to obtain an exact analytical solution for the velocity, though the equation is nonlinear. The flow through the porous solid is assumed to obey the Brinkman equation, and is considered relevant to several applications.
The Poetics of Coming Out and Being Out: Feminist Activism in Cis Lesbian and Trans Women’s Poetic Narratives
Authors: Earles Jennifer
Published: July 2019

While coming out or the telling of sexual selves for LGBTQ+ people is often seen as the final step toward living a free and healthy life, lesbians who also identify as feminists embark on a life-long journey in which the plot ebbs and flows around activism and mobilization. Their goal is not only to come out, but to be out. Both cisgender radical-lesbian feminists and trans feminists consider coming out as not only crucial for the realization of self, but also an important tactic for taking up space and intervening in a heteronormative world. But, while the original theories of radical feminism advocated a fierce anti-essentialism, some contemporary radical feminists continue to focus on biology and questions like “what is a woman?” I hope to refocus the question to ask: how are narrative audiences, discursive forms of text, and spaces important for feminists as they realize lesbian or trans identities and communities? Data come from a historical printed newsletter by self-described radical feminists practicing lesbian separatism and two current micro-blogs, one surrounding radical-feminist narratives and the other around trans feminism. Through a textual analysis, I show how self-proclaimed radical feminists and trans feminists use poetic and emotive writing to produce different kinds of narratives about coming out and being out in different spaces and for unique audiences. Ultimately, these discursive forms are important for communities as members’ stories challenge and are impacted by public narratives of gender, essentialism, and cis- and hetero-normativity.
Using Phenomenological Hermeneutics to Understand the Experiences of Managers Working with Quality Improvement Strategies in an Assisted Living Facility
Authors: Singh Jitendra , Wiese Amy , Sillerud Brandi
Published: July 2019

This qualitative research project aimed to gain an understanding of the experiences of managers who participated in the implementation of quality improvement projects in an assisted living facility. This study employed hermeneutic phenomenology as a research methodology, whereby managers working in an assisted living facility were invited to participate in a 60–75 min semi-structured interview. Six managers participated in the interviews. Five themes were developed from data analysis: (1) Quality improvement (QI) and resident-centered care go hand-in-hand; (2) Constant on-going commitment to continuous improvement is needed to implement QI; (3) Learning to communicate with team-members and residents/caregivers is important to implement QI; (4) Feedback is essential for the implementation of QI initiatives; and (5) Implementing new QI initiatives can be challenging. The managers emphasized the need for leadership commitment, the usage of standardized communication methods, and feedback strategies to ensure the success of QI initiatives. Additionally, the managers indicated that QI is directly related to resident-centered care and that efforts should be made to collect feedback from residents to further improve processes. Additionally, challenges surrounding the implementation of QI have been described. Since there is a scarcity of research on the implementation of QI methods in assisted living facilities, this study can provide practical tips to leaders and administrators.
The Effects of the Dietary and Nutrient Intake on Gynecologic Cancers
Authors: Koshiyama Masafumi
Published: July 2019

The contribution of diet to cancer risk has been considered to be higher in advanced countries than in developing countries. In this paper, I review the current issues (a review of the relevant literature), and the effects of the dietary and nutrient intake on three types of gynecologic cancer (cervical, endometrial and ovarian cancers). In cervical cancer, the most important roles of diet/nutrition in relation to cancer are prophylaxis and countermeasures against human papillomavirus (HPV) infection. The main preventive and reductive factors of cervical cancer are antioxidants, such as vitamin A, C, D and E, carotenoids, vegetables and fruits. These antioxidants may have different abilities to intervene in the natural history of diseases associated with HPV infection. For endometrial cancer, the increase in peripheral estrogens as a result of the aromatization of androgens to estrogens in adipose tissue in obese women and insulin resistance are risk factors. Thus, we must mainly take care to avoid the continuous intake of fat energy and sugar. In ovarian cancer, the etiology has not been fully understood. To the best of our knowledge, the long-term consumption of pro-inflammatory foods, including saturated fat, carbohydrates and animal proteins is a risk factor. The intake of acrylamide is also a risk factor for both endometrial and ovarian cancer. Most papers have been epidemiological studies. Thus, further research using in vitro and in vivo approaches is needed to clarify the effects of the dietary and nutrient intake in detail.

Candida auris is an emerging multidrug-resistant yeast first described in 2009 that has since caused healthcare-associated outbreaks of severe human infections around the world. In some hospitals, it has become a leading cause of invasive candidiasis. C. auris is markedly different from most other pathogenic Candida species in its genetics, antifungal resistance, and ability to spread between patients. The reasons why this fungus began spreading widely in the last decade remain a mystery. We examine available data on C. auris and related species, including genomic epidemiology, phenotypic characteristics, and sites of detection, to put forth hypotheses on its possible origins. C. auris has not been detected in the natural environment; related species have been detected in in plants, insects, and aquatic environments, as well as from human body sites. It can tolerate hypersaline environments and higher temperatures than most Candida species. We explore hypotheses about the pre-emergence niche of C. auris, whether in the environmental or human microbiome, and speculate on factors that might have led to its spread, including the possible roles of healthcare, antifungal use, and environmental changes, including human activities that might have expanded its presence in the environment or caused increased human contact.
An Exact Algorithm for Minimum Vertex Cover Problem
Authors: Wang Luzhi , Hu Shuli , Li Mingyang , Zhou Junping
Published: July 2019

In this paper, we propose a branch-and-bound algorithm to solve exactly the minimum vertex cover (MVC) problem. Since a tight lower bound for MVC has a significant influence on the efficiency of a branch-and-bound algorithm, we define two novel lower bounds to help prune the search space. One is based on the degree of vertices, and the other is based on MaxSAT reasoning. The experiment confirms that our algorithm is faster than previous exact algorithms and can find better results than heuristic algorithms.
Socrative in Higher Education: Game vs. Other Uses
Authors: Faya Cerqueiro Fátima , Martín-Macho Harrison Ana
Published: July 2019

The integration of clickers in Higher Education settings has proved to be particularly useful for enhancing motivation, engagement and performance; for developing cooperative or collaborative tasks; for checking understanding during the lesson; or even for assessment purposes. This paper explores and exemplifies three uses of Socrative, a mobile application specifically designed as a clicker for the classroom. Socrative was used during three sessions with the same group of first-year University students at a Faculty of Education. One of these sessions—a review lesson—was gamified, whereas the other two—a collaborative reading activity seminar, and a lecture—were not. Ad-hoc questionnaires were distributed after each of them. Results suggest that students welcome the use of clickers and that combining them with gamification strategies may increase students’ perceived satisfaction. The experiences described in this paper show how Socrative is an effective means of providing formative feedback and may actually save time during lessons.
Exploring Methods for Predicting Important Utterances Contributing to Meeting Summarization
Authors: Nihei Fumio , Nakano Yukiko I.
Published: July 2019

Meeting minutes are useful, but creating meeting summaries are a time consuming task. Aiming at supporting such task, this paper proposes prediction models for important utterances that should be included in the meeting summary by using multimodal and multiparty features. We will tackle this issue from two approaches: Handcrafted feature models and deep neural network models. The best handcrafted feature model achieved 0.707 in F-measure, and the best deep-learning based verbal and nonverbal model (V-NV model) achieved 0.827 in F-measure. Based on the V-NV model, we implemented a meeting browser, and conducted a user study. The results showed that the proposed meeting browser better contributes to the understanding of the content of the discussion and the participant roles in the discussion than the conventional text-based browser.
Optimized Energy Management Strategies for Campus Hybrid PV–Diesel Systems during Utility Load Shedding Events
Authors: Maritz Jacques
Published: July 2019

The unique situation of utility power curtailment unveils opportunities in the fields of energy management and digital resource management. During utility load shedding events, campuses are typically driven as Photo Voltaic (PV)–diesel generator hybrid systems, of which the main fossil resource driver is diesel. With the appropriate Supervisory Control and Data Acquisition (SCADA) systems, discrete departmental energy policies along with control, forecasting and Internet of Things (IoT) infrastructure, the campus hybrid system could be optimized on a short timescale during the shedding event. In this paper the optimization methodology, required technology infrastructure, possible forecasting algorithms and potential implementation will be discussed.
Selective Engineering for Preparing Entangled Steady States in Cavity QED Setup
Authors: Sousa Emilio H. S. , Roversi J. A.
Published: July 2019

We propose a dissipative scheme to prepare maximally entangled steady states in cavity QED setup, consisting of two two-level atoms interacting with the two counter-propagating whispering-gallery modes (WGMs) of a microtoroidal resonator. Using spontaneous emission and cavity decay as the dissipative quantum dynamical source, we show that the steady state of this system can be steered into a two-atom single state as well as into a two-mode single state. We probed the compound system with weak field coupled to the system via a tapered fiber waveguide, finding it is possible to determine whether the two atoms or two modes are driven to a maximally entangled state. Through the transmission and reflection measurements, without disturbing the atomic state, when the cavity modes are being driven, or without disturbing the cavity field state, when a single atom being driven, one can get the information about the maximal entanglement. We also investigated for both subsystem, two-atom and two-mode states, the entanglement generation and under what conditions one can transfer entanglement from one subsystem to the other. Our scheme can be selectively used to prepare both maximally entangled atomic state as well as maximally entangled cavity-modes state, providing an efficient method for quantum information processing.

The article considers some methodological issues of researching the potential of the regional consumer market, analyzes the indicators characterizing the availability and use of labor potential, infrastructure elements, commodity stocks in Novosibirsk region. Index multiplicative models of the studied indicators allowed us to obtain a quantitative assessment of the influence of factors on the consumer market potential. The development of retail trade turnover is regarded as a social and economic effect of the consumer market functioning. The author came to the conclusion that there is a lack of effective use of the regional consumer market potential and there are problems in the retail regulation system.
Assessment of the Impact of Harmony (Disharmony) of Interests with Key Stakeholders on the Main Indicators of the Functioning of the Enterprise
Authors: Kalinichenko M. P.
Published: July 2019

A distinctive feature of the practice of market-oriented management (marketing management) and management of the sustainable development of modern enterprises is a significant lag behind basic scientific research. The level of harmony of interests between the subject of marketing management (the top management of P.J.S.C. «TAGMET») and its key stakeholders has been established. An integrated assessment of the sustainable development of a metallurgical enterprise was carried out on the basis of an improved methodology. The high closeness of the relationship between the level of harmony of interests of the subject of marketing management and its stakeholders, on the one hand, and the actual level of sustainability of P.J.S.C. «TAGMET», on the other, is established.

Toma mayor importancia esto anterior, si consideramos que en los extremos de la vida (niños y adultos mayores) la equivocación por ingesta de un medicamento equivocado puede ser fatal. Los niños por curiosidad y los adultos mayores por equivocación tienen con más facilidad a tomar medicamentos guardados ¨por si acaso¨ de manera errónea y por tanto, generar problemas de salud que pueden llevar a la muerte cuando lo que se quería era superar un problema de salud.

Published: July 2019

Según Perlmutter (2015), estas nos superan en una relación 1:10. Microbiota es el término acuñado para nombrar al conjunto de microorganismos (principalmente bacterias) que habitan en nuestro organismo, mientras que microbioma hace referencia al conjunto de genes que poseen esos microorganismos. La microbiota se verá afectada por diversas variables, entre las que destacan el uso de antibióticos, la alimentación e inclusive la vía por la que nacen las personas. Todas estas variables crearán un microbioma único para cada sujeto. 

De conformidad con lo expuesto por Domínguez Bello, et. al. (2010), cuando un neonato atraviesa la vagina de la madre durante el parto natural, este se expone a bacterias de los géneros bifidobacterias y lactobacilos principalmente.
