Authors: Orozco-Messana Javier , de la Poza-Plaza Elena , Calabuig-Moreno Raimon
Published: February 2020

There is a growing recognition and acceptance that society needs to develop new pathways to achieve a more sustainable future. Our current model of development poses significant challenges when it comes to achieving a more just society based on respect for nature and human rights, and demands a sustainable economy supported by a new circular model supporting the UN sustainable development goals. Higher Education Institutions (HEIs) accordingly have developed Master programs that are responsible for providing fundamental services in the joint effort towards sustainability. Meanwhile, leading Universities around the world have developed other very relevant programs. The open and unstructured challenge of sustainability poses an obstacle to existing academic structures. Specifically, the built environment is one of the leading contributors to challenges addressed in the programs such as: Anthropogenic climate change, resource depletion, waste generation and pollution, poverty, and inequity. The Interdisciplinary Sustainable Architecture lab (ISAlab) explores these issues as part of a multidisciplinary approach involving the collaboration of leading Universities from different areas on the world through an innovative initiative. This paper explores the experiences of the ISAlab workshop, which has been taking place yearly in Valencia since 2017. The workshop draws together students from a range of disciplines from across engineering and science, law and the social sciences and from a range of countries and backgrounds, including North and South America, Europe, and Asia. Its purpose is to facilitate a rich co-creative learning environment led by (engineering) academic faculties from across Europe (Spain, the UK, France, Germany, Netherlands and Ireland) as well as North America (the US and Canada), as well as local experts who helped provide participants with appropriate context and guidance. The objective is educating future engineers that are capable of finding robust ways to implement sustainability at a practical level on the built environment, taking account of the multidisciplinary perspective and with the incentive of solving real-life problems.

Authors: Kim Jaehwan , Seo Ducksu , Chung You Seok
Published: February 2020

This study investigates the integration of methods for real estate development planning and feasibility studies in the changing business environments of emerging big-data. It examines high-rise mixed-use development projects for the highest best use by combining fuzzy theory; thus, it identifies a big data-based innovative decision-making method for systemizing the various factors expected to influence real estate development. In this context, the study creates new evaluation fields and factors by integrating both conventional and big-data based high-rise mixed-use projects. The weight of each value was calibrated by relative significance and fuzzy measure using the Analytic Hierarchy Process (AHP) method. A measuring technique that applies analysis methodology to the evaluation areas was developed for more objective and clearer evaluation, and its application in the field was proposed. Evaluators can systematically assess the concerned evaluation areas during development project planning by examining the process. The findings also provided implications for the evaluation system’s operation by reflecting the variability of specific conditions of the varying projects in real estate and urban and land use planning.

Published: February 2020

Sustainable financial education is defined as the continuous input of money and time on financial knowledge education after formal schooling. The purpose of this paper is to examine the impact of sustainable financial education on consumer life satisfaction. Utilizing the dataset of Household Consumer Finance of Chinese Urban Residents in 2012 by the China Financial Research Center of Tsinghua University, the variable of sustainable financial education is constructed through the variables of the necessity of financial education, the money spent on financial education, and the time spent on financial education. To improve the estimation results, order probit regression is utilized. The results indicate that financial education is significantly positive to consumer life satisfaction only for a consumer with higher education. Consumers who regard financial education to be of high necessity will feel more satisfied. The results also show that consumers who spend more money and time on financial education after formal schooling will be more satisfied. Moreover, the sustainable impacts of financial education on consumer life satisfaction are verified. In addition, this study provides empirical evidence that suggests that sustainable financial education positively contributes to consumer life satisfaction. The results have implications for policymakers to take measures in enhancing sustainable financial education to improve consumer life satisfaction.

Early detection of pediatric eye problems can prevent future vision loss. This study was to estimate the prevalence of common eye problems among infants born in a resource-constrained emergency setting with a broader aim to prevent future vision loss or blindness among them through early detection and referral. We conducted a cross-sectional survey among 670 infants (0–59 days old) born in Rohingya refugee camps in Bangladesh between March and June of 2019. The most common eye problem found was watering from the eye and accumulation of discharge by which 14.8% of the children were suffering (95% CI: 12.2–17.7). More than 5% of the infants had visual inattention (95% CI: 3.5–7.0), and 4% had redness in their eyes (95% CI: 2.7–5.8). Only 1.9% of infants (95% CI: 1–3.3) had whitish or brown eyeballs, and 1.8% of children might have whitish pupillary reflex (95% CI: 0.9–3.1). None of the eye problems was associated with the gender of the infants. The prevalent eye problems demand eye care set up for the screening of eye problems in the camps with proper referral and availability of referral centres with higher service in the districts.
Phenotypic Drug Discovery for Human African Trypanosomiasis: A Powerful Approach

Published: February 2020

The work began with the screening of a library of 700,000 small molecules for inhibitors of Trypanosoma brucei growth (a phenotypic screen). The resulting set of 1035 hit compounds was reviewed by a team of medicinal chemists, leading to the nomination of 17 chemically distinct scaffolds for further investigation. The first triage step was the assessment for brain permeability (looking for brain levels at least 20% of plasma levels) in order to optimize the chances of developing candidates for treating late-stage human African trypanosomiasis. Eleven scaffolds subsequently underwent hit-to-lead optimization using standard medicinal chemistry approaches. Over a period of six years in an academic setting, 1539 analogs to the 11 scaffolds were synthesized. Eight scaffolds were discontinued either due to insufficient improvement in antiparasitic activity (5), poor pharmacokinetic properties (2), or a slow (static) antiparasitic activity (1). Three scaffolds were optimized to the point of curing the acute and/or chronic T. brucei infection model in mice. The progress was accomplished without knowledge of the mechanism of action (MOA) for the compounds, although the MOA has been discovered in the interim for one compound series. Studies on the safety and toxicity of the compounds are planned to help select candidates for potential clinical development. This research demonstrates the power of the phenotypic drug discovery approach for neglected tropical diseases.
Antiviral Effect of Epigallocatechin Gallate via Impairing Porcine Circovirus Type 2 Attachment to Host Cell Receptor

Published: February 2020

The green tea catechin epigallocatechin gallate (EGCG) exhibits antiviral activity against various viruses. Whether EGCG also inhibits the infectivity of circovirus remains unclear. In this study, we demonstrated the antiviral effect of EGCG on porcine circovirus type 2 (PCV2). EGCG targets PCV2 virions directly and blocks the attachment of virions to host cells. The microscale thermophoresis assay showed EGCG could interact with PCV2 capsid protein in vitro with considerable affinity (Kd = 98.03 ± 4.76 μM), thereby interfering with the binding of the capsid to the cell surface receptor heparan sulfate. The molecular docking analysis of capsid–EGCG interaction identified the key amino acids which formed the binding pocket accommodating EGCG. Amino acids ARG51, ASP70, ARG73 and ASP78 of capsid were found to be critical for maintaining the binding, and the arginine residues were also essential for the electrostatic interaction with heparan sulfate. The rescued mutant viruses also confirm the importance of the key amino acids of the capsid to the antiviral effect of EGCG. Our findings suggest that catechins could act as anti-infective agents against circovirus invasion, as well as provide the basic information for the development and synthesis of structure-based anti-circovirus drugs.

Porcine sapelovirus (PSV) has been detected worldwide in pig populations. Although PSV causes various symptoms such as encephalomyelitis, diarrhea, and pneumonia in pigs, the economic impact of PSV infection remains to be determined. However, information on the distribution and genetic diversity of PSV is quite limited, particularly in Africa. In this study, we investigated the prevalence of PSV infection in Zambia and characterized the isolated PSVs genetically and biologically. We screened 147 fecal samples collected in 2018 and found that the prevalences of PSV infection in suckling pigs and fattening pigs were high (36.2% and 94.0%, respectively). Phylogenetic analyses revealed that the Zambian PSVs were divided into three different lineages (Lineages 1–3) in the clade consisting of Chinese strains. The Zambian PSVs belonging to Lineages 2 and 3 replicated more efficiently than those belonging to Lineage 1 in Vero E6 and BHK cells. Bioinformatic analyses revealed that genetic recombination events had occurred and the recombination breakpoints were located in the L and 2A genes. Our results indicated that at least two biologically distinct PSVs could be circulating in the Zambian pig population and that genetic recombination played a role in the evolution of PSVs.
In Search of Covariates of HIV-1 Subtype B Spread in the United States—A Cautionary Tale of Large-Scale Bayesian Phylogeography

Published: February 2020

Infections with HIV-1 group M subtype B viruses account for the majority of the HIV epidemic in the Western world. Phylogeographic studies have placed the introduction of subtype B in the United States in New York around 1970, where it grew into a major source of spread. Currently, it is estimated that over one million people are living with HIV in the US and that most are infected with subtype B variants. Here, we aim to identify the drivers of HIV-1 subtype B dispersal in the United States by analyzing a collection of 23,588 pol sequences, collected for drug resistance testing from 45 states during 2004–2011. To this end, we introduce a workflow to reduce this large collection of data to more computationally-manageable sample sizes and apply the BEAST framework to test which covariates associate with the spread of HIV-1 across state borders. Our results show that we are able to consistently identify certain predictors of spread under reasonable run times across datasets of up to 10,000 sequences. However, the general lack of phylogenetic structure and the high uncertainty associated with HIV trees make it difficult to interpret the epidemiological relevance of the drivers of spread we are able to identify. While the workflow we present here could be applied to other virus datasets of a similar scale, the characteristic star-like shape of HIV-1 phylogenies poses a serious obstacle to reconstructing a detailed evolutionary and spatial history for HIV-1 subtype B in the US.
Experiences of GP trainees in undertaking telephone consultations: a mixed-methods study
Authors: Chaudhry Umar , Ibison Judith , Harris Tess , Rafi Imran , Johnston Miles , Fawns Tim
Published: February 2020

Background

Primary care telephone consultations are increasingly used for patient triage, reviews, and providing clinical information. They are also a key postgraduate training component yet little is known about GP trainees’ preparation for, or experiences and perceptions of, them.

Aim

To understand the experiences, perceptions, and training of GP trainees in conducting telephone consultations.

Design & setting

A mixed-methods study was undertaken of North Central and East London (NCEL) GP trainees.

Method

A cross-sectional electronic survey of trainees was performed with subsequent semi-structured interviews. Survey data were analysed using descriptive statistics, and qualitative data using thematic analysis.

Results

The survey response was 16% (n = 100/618), and 10 participated in semi-structured interviews. Trainees felt least confident with complicated telephone consulting, and there was a strong positive correlation between the percentage reporting having received training and their confidence (R2 = 0.71, P<0.0001). Positive experiences included managing workload and convenience. Negative experiences included complex encounters, communication barriers, and absence of examination. Trainees reported that training for telephone consultations needed strengthening, and that recently introduced audio-clinical observation tools (COTs) were useful. Positive correlations were found between the length of out-of-hours (OOH) but not in-hours training and the level of supervision or feedback received for telephone consultations.

Conclusion

This project sheds light on GP trainees’ current experiences of telephone consultations and the need to enhance future training. The findings will inform a wider debate among stakeholders and postgraduate learners regarding training for telephone consultations, and potentially for other remote technologies.

Published: February 2020

Congestive Hearth Failure (CHF) is one of the biggest contributors to death in the world. The recurrence of recurrence after hospitalization in CHF patients increases every year due to lack of knowledge of the disease, treatment to be undertaken and care after returning from health services. One effort that can be done in reducing the recurrence rate in patients with CHF yaiyu is by planning treatment activities that will be undertaken by patients starting from thebeginning of entering health services until planning to go home.Discharge Planning is a process that starts when a patient enters health services to return home from health services so that patients get continuous health care both in the healing process and in maintaining their health status until the patient feels ready to return to his environment and is satisfied with treatment that has been undertaken in health services. The purpose of this study was to determine the effectiveness of the application of discharge planning to the readiness of returning home and patient satisfaction of Congestive Heart Failure (CHF) patients at Murni Teguh Memorial Hospital. The research method that will be used in this study is Quasi Experiment (quasi-experimental) post test only non equivalent control group, where in this design there are no restrictions on randomization when entering subjects into the treatment group or the control group. The sample in this study were 90 respondents (45 treatment group respondents and 45 control group respondents). The sampling technique in this study with non probability techniques with consecutive sampling approach. Bivariate analysis is performed to test hypotheses or to determine the effectiveness of the relevant variables used are non-parametric statistics with the type of test mann withney t-test. The results of the study are significant if the p value is less than 0.05 (p value <0.05). The results of this study indicate that the application of discharge planning is effective in increasing the readiness and satisfaction of CHF patients.

Menstrual Hygiene Management (MHM) is the management of hygiene and health when women experience menstruation. The main problem in adolescents related to menstruation is the lack of knowledge about MSM and poor water sanitation. Many girls don't have the right understanding that menstruation is a normal biological process. Community service aims to improve students' knowledge and attitudes about menstrual health management. The method used is socializing; identify the state of menstrual health service facilities in schools: bathrooms, water, information; carry out bathroom renovations; provide educational media about menstrual health management in the form of posters, videos, leaflets, modules and flip sheets. Pre-test and post-test aims to identify students' knowledge and attitudes about menstrual health management. Analysis of the data used is the dependent t test. The knowledge of students before being given health education majority was in the sufficient category and thereafter increased to good. Likewise, students' attitudes increase to be positive. The statistical test results obtained mean difference of 7.72 and P Value = 0.001, it can be concluded that there is a significant effect of health education on knowledge. For attitudes the mean difference is 1.62 and the P value  = 0.001, it can be concluded that there is a significant influence on health education on student attitudes. Therefore it is suggested to the school to include this topic in the subject matter. So students can apply it early and their reproductive health can be maintained.

We proposed in among below the recovery of archeological research what was done now more 40 years ago, at Budureasca, a collinear area in north-east Prahova County. Our work is meant to be a support for publishing the results of the research by the archaeologists, during activity or possibly a resonable time after the start. The work performed and the problems encountered for the exposre of the information below, stengthened this conviction. Also, we follow the introducing in the scientific field of some rare archaeological finds in Muntenia area which can be evaluated by other researchers in a more varied background. Between the findings of Budureasca, which can be considered specials are those belonging to the funeral decorations of Bronze Age. In area " Puţul Tătarului", were intercepted more funeral arrangements of whichonly a few have been fully investigated. They were situated on an necropolis assigned to an early aspect of the bronze era with analogy to the cultural surroundings of Glina III– Schnekenberg, chronologically placed lightly prior an early stage of Monteoru’s culture. Because of the incomplete archeological information, this note have only a preliminary character. From the point of view of the funerary arrangements, cist graves surrounded by ring of rocks, over which mounds of ground were builded and other elements too, of rite and ritual, the Budureasca necropolis has for now in these area an exceptional character. We do not know in the area that is discussed similar discoveries for this chronological extent. We also notice the existence in this necropolis of possible secular burials rendered by the presence of incinerated bones laid by the rings interior, of some vessels disposed in the exterior of the cystic. The chronological segment that was used this necropolis covers the last stages of the evolution of the Glina culture and the early Monteoru culture. The researchs are in progress in this archaeological site and could offer the chance discovery of new funeral arrangements or the completion of partially captured oldest archaeological excavations.

The present paper reopens the discussion over several antropomorphic figurines found during the excavations on the Vidra tell. The figurines are part of the collection of the Bucharest City Museum (MMB). The majority of them were assigned by the author of the excavations, D. V. Rosetti, to the B1 phase of the Gumelnitsa culture. The exact archaeological context of the figurines is unknown. The authors used for the study of this lot a relatively recent method of investigation – the X-ray tomography. The X-ray equipment was specifically built for applications in archaeology and is unique in Romania. The X-ray tomography proved to be a very useful tool in archaeological research and cultural heritage studies, presenting a series of advantages.
Istros et les Séleucides au IIIe siècle av. J.-C. à la lumière des sources numismatiques

Published: February 2020

Recent, publicarea unui mare tezaur monetar, format din tetradrahme de argint, aruncă o lumină nouă asupra raporturilor Seleucizilor cu oraşele vest-pontice şi îndeosebi cu Istros. Ponderea neobişnuit de mare a tetradrahmelor bătute de Odessos, Mesambria şi Callatis în structura tezaurului sugerează o politică monetară comună a celor trei oraşe, într-un anumit moment, determinată de evoluţia factorilor politici din zonă. Deosebit de interesant este lotul alcătuit din 35 de tetradrahme seleucide, cu o iconografie aparte : capul suveranului pe avers şi Apollo pe revers. Dintre acestea, 12 tetradrahme care poartă pe revers legenda ANTIOXOY şi sigla IΣ au fost atribuite oraşului Istros care le-ar fi bătut în timpul regilor Antiochos II (261– 246) şi Antiochos Hierax (246– 226). Baterea unor tetradrahme de tip seleucid, fapt neobişnuit pentru oraşele aflate pe litoralul de vest al Mării Negre, indică o legătură specială între Istros şi Regatul Seleucid care poate fi surprinsă şi pe emisiunile din aur. Analiza materialului numismatic arată că seria de tetradrahme cu IΣ pe revers şi portretul lui Antiochos II pe avers ar putea fi datată în contextul celui de-al doilea război sirian (260– 253). Baterea tetradrahmelor de tip seleucid cu IΣ pe revers atribuite lui Antiochos Hierax a avut loc în contextul celui de-al treilea război sirian sau imediat după, în anii 240, când izbucneşte conflictul cu Seleucos II. Sunt discutate relaţiile politice dintre Istros şi Regatul Seleucid în secolul al III-lea a. Chr. în lumina izvoarelor numismatice.

Petrographic analysis of raw materials from Lespezi-Lutărie: implications for Upper Palaeolithic sites from the Middle and Lower Bistriţa Valley
Authors: Ciornei Alexandru
Published: February 2020

This study presents the petrographic analysis of lithic raw materials from level IV of Lespezi-Lutărie site (Upper Palaeolithic, Lower Bistriţa Valley, Bacău County, Romania), resulting in the identification of 16 varieties related to different rock types : sandstones (quartzarenites, calcarenite), black shale, bedded cherts (Early Oligocene menilite and detritalrich spiculite chert), peloidal cherts, Eocene and Cretaceous nodular cherts. Part of the varieties identified reflect the availability, abundance, accessibility and variability of raw materials in the surrounding area (Tarcău and Vrancea nappes), while the ones brought in from other regions represent imported materials related to cultural relations and geographically available circulation routes between Gravettian communities from the Bistriţa, Prut and Danube valleys. The use of both coarser (sandstones) and fine-grained lithologies (shale, cherts), from poorly silicified (sandstones, shale) to strongly and very strongly silicified (cherts from chalk) reflects acquisition patterns guided by specific needs and uses of tools. External macroscopic features indicate secondary sources (alluvial deposits, riverbeds) for all varieties determined.

Since its inception, the Romanian archaeological school of the Palaeolithic maintained the interpretation of archaeological layers through the lenses of the geomorphological data as an objective. Our study presents one of the situations in which archaeological researches did not benefit from a direct collaboration between the two fields of inquiry, which led to an erroneous understanding of the sedimentary genesis in the Palaeolithic settlement of Malu Dinu Buzea (Covasna Department). Recent observations offered a glimpse of both vertical and horizontal movement of the archaeological material, due to the periodical reactivation of a dejection cone, and to sedimentary peculiarities. The technological analysis of the recently excavated lithic assemblage revealed the existence of a single, heavily disturbed cultural unit, found in secondary position, along with numerous naturally fragmented flint, sandstone, quartzite, and limestone blocks. The largest part of the technological and typological features of the mostly local flint assemblage indicates a possible final Upper Palaeolithic timing for its origin, with no arguments in favour of a putative Aurignacian designation, and only several hints at a Tardenoisian one, both previously stated for what used to be recognized as a twofolded cultural sequence.

Céramiques anatoliennes du littoral nord du Pont-Euxin archaïque. Problèmes en suspens / Pottery finds of Anatolian type from the northern Black Sea shore. Problems of origin and delivery routes
Authors: Dupont Pierre
Published: February 2020

Descoperirile recente de vase anatoliene, de tip frigian recent și lidian, în așezări grecești din Pontul nord‐ vestic (Istros, Berezan, Olbia) și nord‐ estic (Pantikapaion), pun problema atât a centrelor lor de producţie, cât şi a traseului urmat de acestea din zona anatoliană. Presupunem că vasele de tip frigian recent descoperite la Pantikapaion au urmat același itinerariu maritim de coastă prin vest, trecând prin Bosfor și urcând spre nord, ca și vasele de tip anatolian descoperite la Istros și Berezan‐ Olbia.

Moments in the biography of the Neolithic vessels of Vădastra tradition at the Lower Danube
Authors: Dragoman Radu-Alexandru
Published: February 2020

With few exceptions, many earlier and more recent approaches to Neolithic ceramics in Romania have unfortunately been informed by the modernist dichotomies between the sacred and the profane, the functional and the symbolic, something that became the subject of much criticism in postprocessual archaeologies as of the 1980s. In contrast with a modernist perspective, in this text I have chosen to apply a biographical approach, which, in my opinion, has the merit of unifying all of the aspects – technological, functional, symbolic, etc. – that until now have been treated distinctly. The subject of this article is a series of Neolithic vessels attributed to the Vădastra tradition of southern Romania and north-western Bulgaria dated to ca. 5200– 4900 BC. With the exception of one vessel from Slatina, two vessels from Hotărani and two so-called Vădastra-type “ imports” from Hungary, all of the vessels discussed here originate from the Vădastra – Măgura Fetelor/ Dealul Cișmelei settlement located in southern Oltenia, Romania. While Neolithic ceramics from Vădastra as a whole have already been the subject of a previous biographical study, on this occasion the analysis takes place at the level of the individual objects. While in no way claiming to have provided complete biographies or to have exhausted the repertoire of existing and possible biographies, the examples discussed here are illustrative of a series of key moments in the biography of the Vădastra vessels and thus help us achieve a better understanding of the relationships between prehistoric and modern peoples, on the one hand, and Neolithic vessels, on the other.
Sharkskin-Inspired Magnetoactive Reconfigurable Acoustic Metamaterials

Most of the existing acoustic metamaterials rely on architected structures with fixed configurations, and thus, their properties cannot be modulated once the structures are fabricated. Emerging active acoustic metamaterials highlight a promising opportunity to on-demand switch property states; however, they typically require tethered loads, such as mechanical compression or pneumatic actuation. Using untethered physical stimuli to actively switch property states of acoustic metamaterials remains largely unexplored. Here, inspired by the sharkskin denticles, we present a class of active acoustic metamaterials whose configurations can be on-demand switched via untethered magnetic fields, thus enabling active switching of acoustic transmission, wave guiding, logic operation, and reciprocity. The key mechanism relies on magnetically deformable Mie resonator pillar (MRP) arrays that can be tuned between vertical and bent states corresponding to the acoustic forbidding and conducting, respectively. The MRPs are made of a magnetoactive elastomer and feature wavy air channels to enable an artificial Mie resonance within a designed frequency regime. The Mie resonance induces an acoustic bandgap, which is closed when pillars are selectively bent by a sufficiently large magnetic field. These magnetoactive MRPs are further harnessed to design stimuli-controlled reconfigurable acoustic switches, logic gates, and diodes. Capable of creating the first generation of untethered-stimuli-induced active acoustic metadevices, the present paradigm may find broad engineering applications, ranging from noise control and audio modulation to sonic camouflage.

Un sistema de semillas es la combinación de componentes, procesos y su organización para la producción y comercialización de este insumo para la siembra de una o más especies. Debido a la importancia de la puesta en vigor de la Ley Federal de Producción, Certificación y Comercio de Semillas en México y de la Ley Federal de Variedades Vegetales(LFVV), en el presente estudio se analizó la evolución de la producción de semilla certificada para identificar su relación con los cambios en el marco legal en materia de semillas. Se utilizó la base de datos del programa de producción de semilla certificada publicada por el Servicio Nacional de Inspección y Certificación de Semillas para el periodo 1988-2013. Se encontró que a partir de la década de los 1980s se presentó una reducción en la producción de semillas certificadas como resultado de una disminución en la participación del sector público y el inicio de la participación del sector privado. Para la década de los 1990s se presentaron cambios con una disminución de la superficie de 144,219 ha y la producción de 332,500 t, todo esto en el contexto de integración de México como miembro de la Unión Internacional para la Protección de las Obtenciones Vegetales (UPOV) y de la publicación de LFVV. La producción de semillas certificadas a partir del año 2000 presentó un incremento tanto en superficie como en volumen. De acuerdo con los datos publicados en el Catálogo Nacional de Variedades Vegetales y en la Gaceta Oficial de los Derechos de Obtentor, el sector privado cuenta con mayor participación en el registro de variedades de uso común y con derechos de obtentor. México cuenta con regulación suficiente en materia de producción, certificación y comercio de semillas y en protección de derechos de obtentor, así como con un sistema diversificado en el que concurren el sector público, el social y privado; no obstante, se observó una concentración tanto en solicitantes de registros como en cultivos con producción de semilla certificada.

La ruptura en semillas reduce la germinación, aun si el daño no ocurre sobre tejido metabólico, y ocasiona un incremento de ataque de microorganismos. Comprender la mecánica de la falla de tejidos permitirá desarrollar condiciones de manejo más apropiadas para reducir los daños mecánicos o sus efectos, por lo que el objetivo de este estudio fue conocer la naturaleza de la falla de tejidos de la semilla de maíz (Zea mays L.) sometida a compresión axial, según el tipo de endospermo y contenido de humedad. Se evaluó la calidad fisiológica y el daño celular de semillas de maíz de tres variedades con endospermo harinoso (Cacahuacintle), semi-dentado (HS-2) y cristalino (Palomero), con contenidos de humedad de 12 y 20 % y comprimidas a velocidad de 1 mm min-1 entre platos pulidos hasta justo el momento en que se presentó la ruptura. En la zona de ruptura, el endospermo mostró una proporción de área de 92.20 % con ruptura de pared celular, superior al área de 7.8 % sin ruptura de pared celular; la aleurona también presentó una proporción de células con ruptura de pared celular de 87.8 %, superior a la de células sin ruptura de pared celular (12.3 %). No hubo fracturas sobre tejido embrionario ni escutelo; no obstante, la germinación en semillas sometidas a ruptura fue inferior (55.0 %) a la del testigo (85.2 %). La proporción de ruptura celular entre las dos humedades estudiadas difirió de manera significativa. No hubo diferencias significativas en la proporción de ruptura celular entre variedades. La germinación estándar de semillas de Cacahuacintle y HS2-2 comprimidas a ruptura fue superior con humedad de 12 % con respecto a aquellas comprimidas con humedad de 20 %.
