The interest in aquaponics has been increasing in the last years since it may become one of the solutions for food scarcity around the world and the need for green and sustainable technologies in the food industry. Nevertheless, an aquaponics process is quite complex and the need for further studies about the parameter’s relationships that establish a base for future technological implementations is needed. This research project presents the development of a framework that involves the creation of a wireless sensing module that uses a pH, electroconductivity, water temperature, light resistor, air humidity, and air temperature sensor and the connection to a database capable of storing and linking the information to a quality assessment tool that can be used for future smart applications towards the feasibility of aquaponics at commercial scale.

We are currently witnessing a worldwide event caused by the pandemic outbreak derived from the new SARS-CoV-2 virus, which requires the generation of knowledge. Due to its novelty, many hypotheses and theories are discussed daily regarding the origin of this new virus. Several studies are focused on demonstrating how similar it is to other viruses.To highlight the differences of SARS-CoV-2 with other SARS viruses, from a comparative genomics analysis, and determine if these can be attributed to manipulation events.Complete genomes of two SARS viruses were downloaded, along with other six of human coronaviruses, and 16 of SARS-type coronaviruses. These were analyzed using the BLAST Ring Image Generator tool; afterwards, the evident differences were examined by MAFFT and BLAST programs.High identity was observed in fragments of the mammalian SARS-like genomes with the SARS-CoV-1 and SARS-CoV-2 genomes, identifying three main nucleotide differences, in the ORF1ab nsp3 region gene, in the receptor recognition S gene, and in the ORF8 gene, with which the SARS-type strains of mammals can be separated into the SARS-CoV-1 and SARS-CoV-2 type.The complete SARS-CoV-2 genome has high identity with mammalian SARS-type strains, which is why its most probable appearance could be the result of natural evolution.en este momento somos testigos de un evento de magnitud mundial provocado por el brote pandémico derivado del nuevo virus SARS-CoV-2, lo cual requiere la generación de conocimiento.

With significant advancement in information technologies due to Industry 4.0, Digital Twin (DT) has gained increasing attention as it offers an enabling tool to realize digitally-driven and cloud-enabled production systems. The idea of DT involves the concrete realization of mirroring the physical entities in the virtual world. Given the nonlinear dynamics and uncertainty involved in production systems, the proper design, and adaptability of a DT model remain a challenge. To address this issue, the given study proposes a methodology to develop the DT model for production systems, mainly focusing on robot-based production lines. The implementation and validation of the model are carried through a case study within a Learning Factory that involves data extraction from a physical pick and place robotic production line and using it as an input for the virtual entity to determine and analyze lean process parameters such as cycle time and total lead time. The proposed study also facilitates Lean Industry 4.0 concepts. The gathered results show that DT technology not only enables remote monitoring but also improves the performance of the production system.

Information about clinical outcome and reperfusion treatment in Latin-America is not widely known. Our aim was to determine this association and other clinical factors according to the initial clinical severity in functional outcome in the population from the Latin-America Stroke Registry (LASE). Methods: Data were collected prospectively from consecutive patients admitted from January 2012-January 2017 in 20 Latin-American centers. The initial clinical severity was stratified according to the baseline NIHSS; 0-3 minor, 4-7 mild, 8-14 moderate, and ≥15 severe. Clinical outcome was defined by mRS at 3 months, dichotomized in good (0-2) and poor (3-6) groups for univariate and logistic multivariate analysis. Results: Among 5381 patients, 823(15.3%) patients received any reperfusion treatment. Of these, 84.7% received I.V. fibrinolytic, 13.2% bridging therapy, and 0.9 % primary endovascular treatment. In overall, according to initial clinical deficit by NIHSS, reperfusion treatment was associated with good outcome in mild (82.8% Vs 66.1% p=0.005), moderate (55.9 % vs. 41.6% p=0.002) and severe deficits (29.4 Vs. 18.8% p=0.002). In patients with a baseline NIHSS ≥4, multivariate analysis showed that lower NIHSS (p Conclusion: In this study, the rate of reperfusion treatment in 20 stroke Latin-American centers is lower than that reported from other world regions. A significant association between reperfusion treatment and good clinical outcome was observed in mild up to severe baseline deficit in our study. The effect of ischemic cardiopathy in clinical outcome in reperfusion treated patients deserves further studies. Its association with recanalization, remote pre-conditioning ischemia and collateral circulation could be explored in our population.

Eight complexes of various aromatic molecules with water have been studied theoretically at the local Moller–Plesset 2nd order theory (LMP2)/aug-cc-pVTZ(-f)//LMP2/6-31+G* level of theory. Two types of complexes can be formed, depending on the electronic structure of aromatic molecules. Donor hydrocarbons form A-type complexes, while aromatics bearing electron-withdrawing substituents form B-type complexes. A-type complexes are stabilized due to π–H interactions with the OH bond pointing to the aromatic molecule plane, while B-type complexes have geometry with the oxygen atom pointing to the aromatic molecule plane stabilized by the interaction of highest occupied molecular orbital (HOMO) of water molecule with π* orbitals of the aromatics. It has been found that a (HOMO–lowest unoccupied molecular orbital (LUMO)/2 value of aromatic molecule, which can be called “molecular electronegativity,” is useful to predict the type of complex formed by aromatic molecule and water. Aromatic hydrocarbons with “molecular electronegativity” of

Morder y asir son los principales mecanismos utilizados por los reptiles para capturar a sus presas. Son tan simples, que sólo requieren que el animal coloque su cabeza cerca del alimento. La aproximación puede realizarse con un rápido movimiento de la cabeza y del cuello, o al desplazar todo el cuerpo. Algunas especies complementan estos métodos con colmillos y glándulas de veneno, como los helodermátidos (escorpión y monstruo de Gila), los eláfidos (coralillo, serpiente marina, etc.) y los vipéridos (cascabel, zolcuate, etc.); o con dientes agudos, como en los crocodílidos.

The ONIOM (MP2:PM3) model in combination with local implementation of MP2 single-point energy evaluation was used to model the C60–water complex. In agreement with experimental data, stabilization of the complex can be described in terms of interaction between the lone electron pair of water oxygen and π*-orbitals of fullerene with electron correlation being the most important contribution to the complex stabilization. It was found that for qualitatively correct description of C60–water complex geometry it is essential to have at least 12 carbon atoms of C60 molecule and water molecule in high MP2 ONIOM layer and use a basis set of at least 6-31+G(d,p) quality. © 2003 Wiley Periodicals, Inc.

Benzene, pyrimidine, and naphthalene dimers have been studied at canonical MP2, LMP2, and MP4(SDTQ) levels of theory. It has been shown that the LMP2 method is superior to canonical MP2 due to reduced BSSE. Thus, basis set limit-extrapolated LMP2 binding energies of T-shaped and parallel displaced (PD) benzene dimers are nearly the same, as has been found in higher level ab initio calculations. MP4(SDTQ) binding energies calculated at LMP2 optimized geometries are always more negative than those calculated for MP2-optimized geometries. MP4(SDTQ)/CC-pVDZ-corrected complete basis set-extrapolated LMP2 binding energies of T-shaped and PD dimers of benzene and naphthalene were found to be −2.80, −2.59 and −4.39, −6.29 kcal/mol, respectively.

The complex formation between fullerene C60 and simple donor molecules such as dimethyl ether, dimethylamine, dimethylsulfide, furan, pyrrole, and thiophene has been studied applying the hybrid MP2/6-31G(d′):PM3 ONIOM approach for geometry optimization. Local implementation of Moller–Plesset perturbation theory in combination with 6-31G(d) and 6-311G(d,p) basis sets was used for binding energies estimation of fullerene complexes. Two factors were found to contribute most to the complex stability: the polarizability and molecular volume of donor molecule. As follows from positive stabilization energies at the Hartree–Fock level, the stabilization of fullerene complexes is entirely due to dispersion interactions in accordance with available experimental data. The calculations show that for donors of similar molecular volume the binding energy of molecular complex increases with polarizability of donor molecules. Similarly, for such complexes the partial charges on molecules increase with decreasing of ionization potentials of donor molecules. © 2002 Wiley Periodicals, Inc. Int J Quantum Chem, 2002

Background Congenital scoliosis (CS) is defined as lateral curvatures of the spine provoked by the anomalous development of the vertebral bodies. It is associated with neuromuscular anomalies, which can be genetic, caused by the compensation of discrepancies in the length of the extremities or intrarachidian anomalies. Methods This study was carried out in 2-year-old female, showed alterations in the gait, mainly in the hind limbs, a clumsy gait and a slight claudication in the right hindlimb. To perform the imaging study were: X-Ray projections and Computerized Axial Tomography, neurophysiological evaluation was performed by means somatosensory-evoked potentials of the tibial nerve (SEPTN). Results The results showed an enlargement of the latencies from the L5 to the cortex, mainly in the left afference, correlated with the imaging studies. Conclusions There is no doubt that the concurrent use of different diagnostic tools complements knowledge regarding the physiopathogenesis of these osteopathologies.

1. A multi-wavelength photometric catalog of about 38 000 sources from 2 μm to 1.1 mm in a 1 square degree are of the Carina South Pillar Region has been constructed. This catalog is based on millimeter observations with the bolometer array AzTEC as a visitor instrument to ASTE telescope and IR public available data. It is found that 118/38000 of the total sources in the region are millimeter AzTEC sources. 2. This work is focused on the population of 118 millimeter point-like sources with and without IR counterpart, which are identified as either YSO candidates (YSOc) or as possible starless cores (Enoch et al., 2008, and references therein), respectively. After a visual inspection of 52/118 millimeter sources with S/N > 4 (or integrated flux > 300 mJy), a total of 12 YSOc and 40 starless cores are reported. 3. A primary observational classification of embedded sources, based on estimations of the IR index αIR _d log (λF λ) /d log λ (λ from 2.12 to 24 μm), gives about 33 700 objects classified as Class III, 2300 as Class II and 900 as Class 0/I. 4. With the help of NIR diagnostic diagrams, a mean extinction value AV ~15 mag from embedded main sequence stars is estimated. Furthermore, the MIR diagrams show also a more embedded young object population with larger AV values. Although a complete study based on mid-IR and millimeter interstellar extinction maps are necessary to better estimate individual AV values, the extinction estimated from NIR photometry provides an acceptable constrain to physical parameters from the fitted models (Robitaille et al., 2007) to the YSOc sample. 5. In summary, 17% of AzTEC sources (S/N > 4) lie within a pillar body, and only 3-4 associated with the pillar head. Also 15% are located within an irradiated edge structure. Almost 40% show IR sources near or associated the millimeter emission, and 25% show more than one source related to the millimeter emission. All of these sources are good candidates to be observed with larger angular resolution (e.g., LMT, ALMA).

Background Regarding the good practice in the laboratory work, it is essential to have a broad spectrum of biochemical and hematological references in pregnant females to determine the health status of the colony. Objective To establish reference values to reveal changes in hematology and blood chemistry in pregnant rhesus monkeys (Macaca mulatta) in their first trimester of pregnancy. Methods Twenty-eight females in reproductive stage were used, divided into two groups: 14 pregnant macaques in their first trimester and 14 non-pregnant used as the control group. Blood samples were collected for the hematological test and blood chemistry. Results The results showed significant difference in the blood chemistry for the following parameters: glucose, total bilirubin, and total protein. The hematological evaluation revealed significant difference in leukocytes and neutrophils. Conclusions These findings offer a reference range and provide a basis for improvement in techniques and refinement of clinical processes in these specimens.

Somatosensory evoked potentials (SSEP) have been described as excellent indicators of the degree of medullar injury in degenerative and metabolic diseases of the central nervous system (CNS). The prevalence of neural tube defects (NTD) is 6 cases/10,000 live newborns worldwide. It is thought that genetic as well as environmental factors contribute to the etiology of NTD. The objective of this study was to analyze and compare the latencies obtained by means of SSEP in a clinically healthy monkey vs. rhesus monkeys with intrauterine surgery in order to simulate surgically the neural tube defect (myelomengocele) by performing an intrauterine laminectomy and in which later the defect was corrected.This study was performed using three non-human primates of the Macaca mulatta species. There were practice intrauterine surgeries in two monkeys to simulate the neurological defect produced by myelomeningocele, using the third monkey as control. For statistical methodology four monkeys were used. They were born by natural birth without any surgical manipulation. With the cesarean-obtained products, stimulation was performed of the tibial and median nerve.We observed that the hind limbs were the most affected, in particular, the left afferent of the monkey. The spinal cord was exposed to amniotic fluid, and there were no significant differences in the forelimbs.The use of SSEP provides valuable information regarding preservation of sensorial functions in a variety of experimental neurological abnormalities.

Strabismus has been related to different alterations of brain functions and learning in children. Early treatment for visuomotor functions may improve the executive areas of intelligence. We undertook this study to demonstrate changes of visuomotor function and intelligence in children after strabismus treatment.This is a prospective study of patients with strabismus, before and after treatment. We applied the Human Figure Test, Visuomotor Bender Test, and Intelligence Test.We included nine children with an average age of 8.7 years (± 2.4 years). Stereopsis result was 724 arc sec. Visual acuity was 0.16 logMAR ± 0.15. Verbal intelligence was 91.1 ± 11, executive intelligence (EI) was 86.7 ± 8, and global intelligence (GI) was 91 ± 10. Correlation coefficient of EI was significantly related to stereopsis (-0.2), visual acuity (-0.1) and Bender (-0.1). GI results were higher than statistical prognosis (88.16 for x = 90).We demonstrated improvement in binocularity and psychoadaptive areas related to EI after strabismus and amblyopia treatment.
