Published: January 2021

Near real-time urban traffic analysis and prediction are paramount for effective intelligent transport systems. Whilst there is a plethora of research on advanced approaches to study traffic recently, only one-third of them has focused on urban arterials. A ready-to-use framework to support decision making in local traffic bureaus using largely available IoT sensors, especially CCTV, is yet to be developed. This study presents an end-to-end urban traffic volume detection and prediction framework using CCTV image series. The framework incorporates a novel Faster R-CNN to generate vehicle counts and quantify traffic conditions. Then it investigates the performance of a statistical-based model (SARIMAX), a machine learning (random forest; RF) and a deep learning (LSTM) model to predict traffic volume 30 min in the future. Tests at six locations with varying traffic conditions under different lengths of past time series are used to train the prediction models. RF and LSTM provided the most accurate predictions, with RF being faster than LSTM. The developed framework has been successfully applied to fill data gaps under adverse weather conditions when data are missing. It can be potentially implemented in near real time at any CCTV location and integrated into an online visualization platform.

Published: January 2021

Computation offloading enables intensive computational tasks in edge computing to be separated into multiple computing resources of the server to overcome hardware limitations. Deep learning derives the inference approach based on the learning approach with a volume of data using a sufficient computing resource. However, deploying the domain-specific inference approaches to edge computing provides intelligent services close to the edge of the networks. In this paper, we propose intelligent edge computing by providing a dynamic inference approach for building environment control. The dynamic inference approach is provided based on the rules engine that is deployed on the edge gateway to select an inference function by the triggered rule. The edge gateway is deployed in the entry of a network edge and provides comprehensive functions, including device management, device proxy, client service, intelligent service and rules engine. The functions are provided by microservices provider modules that enable flexibility, extensibility and light weight for offloading domain-specific solutions to the edge gateway. Additionally, the intelligent services can be updated through offloading the microservices provider module with the inference models. Then, using the rules engine, the edge gateway operates an intelligent scenario based on the deployed rule profile by requesting the inference model of the intelligent service provider. The inference models are derived by training the building user data with the deep learning model using the edge server, which provides a high-performance computing resource. The intelligent service provider includes inference models and provides intelligent functions in the edge gateway using a constrained hardware resource based on microservices. Moreover, for bridging the Internet of Things (IoT) device network to the Internet, the gateway provides device management and proxy to enable device access to web clients.

Published: January 2021

Considering the complexity of the physical model of wildfire occurrence, this paper develops a method to evaluate the wildfire risk of transmission-line corridors based on Naïve Bayes Network (NBN). First, the data of 14 wildfire-related factors including anthropogenic, physiographic, and meteorologic factors, were collected and analyzed. Then, the relief algorithm is used to rank the importance of factors according to their impacts on wildfire occurrence. After eliminating the least important factors in turn, an optimal wildfire risk assessment model for transmission-line corridors was constructed based on the NBN. Finally, this model was carried out and visualized in Guangxi province in southern China. Then a cost function was proposed to further verify the applicability of the wildfire risk distribution map. The fire events monitored by satellites during the first season in 2020 shows that 81.8% of fires fall in high- and very-high-risk regions.

Published: January 2021

Detection of the loading volume of mining trucks is an important task in open pit mining. Aiming at the addressing the current problems of low accuracy and high cost of the detection of the loading volume of mining trucks, this paper proposes a mining truck loading volume detection model based on deep learning and image recognition. The training and test data of the model consists of 6000 sets of images taken in a laboratory environment. After image preprocessing, the VGG16 network model is used to pre classify the ore images. The classification results are displayed and the possibility of each category is determined. Then, the loading volume of mining trucks is calculated by using the classification results and the least squares algorithm. By using the labeled image data of five kinds of mining truck loading volume, the arbitrary loading volume detection of mining trucks is realized, which effectively solves the problem of a lack of labeled data types caused by the difficulty in obtaining mine data. Root mean square error (RMSE) and mean absolute error (MAE) are used to evaluate the fitting effect of the model. The experimental results show that the model has high prediction accuracy. The average absolute error is 17.85 cm3. In addition, this paper uses 400 real mining truck images of open-pit mines to verify the model and the average absolute error is 2.53 m3. The experimental results show that the model has good generality and can be applied well to the actual production of open-pit mines.
Micro Non-Uniform Linear Array (MNULA) for Ultrasound Plane Wave Imaging
Authors: Tang Yujia , Li Zhangjian , Cui Yaoyao , Yang Chen , Lv Jiabing , Jiao Yang
Published: January 2021

Ultrasound plane wave imaging technology has been applied to more clinical situations than ever before because of its rapid imaging speed and stable imaging quality. Most transducers used in plane wave imaging are linear arrays, but their structures limit the application of plane wave imaging technology in some special clinical situations, especially in the endoscopic environment. In the endoscopic environment, the size of the linear array transducer is strictly miniaturized, and the imaging range is also limited to the near field. Meanwhile, the near field of a micro linear array has serious mutual interferences between elements, which is against the imaging quality of near field. Therefore, we propose a new structure of a micro ultrasound linear array for plane wave imaging. In this paper, a theoretical comparison is given through sound field and imaging simulations. On the basis of primary work and laboratory technology, micro uniform and non-uniform linear arrays were made and experimented with the phantom setting. We selected appropriate evaluation parameters to verify the imaging results. Finally, we concluded that the micro non-uniform linear array eliminated the artifacts better than the micro uniform linear array without the additional use of signal processing methods, especially for target points in the near-field. We believe this study provides a possible solution for plane wave imaging in cramped environments like endoscopy.

Published: January 2021

This paper presents the design, development and testing of a low-cost Structural Health Monitoring (SHM) system based on MEMS (Micro Electro-Mechanical Systems) triaxial accelerometers. A new control system composed by a myRIO platform, managed by specific LabVIEW software, has been developed. The LabVIEW software also computes the frequency response functions for the subsequent modal analysis. The proposed SHM system was validated by comparing the data measured by this set-up with a conventional SHM system based on piezoelectric accelerometers. After carrying out some validation tests, a high correlation can be appreciated in the behavior of both systems, being possible to conclude that the proposed system is sufficiently accurate and sensitive for operative purposes, apart from being significantly more affordable than the traditional one.
Quantifying Coordination and Variability in the Lower Extremities after Anterior Cruciate Ligament Reconstruction
Authors: Park Sangheon , Yoon Sukhoon
Published: January 2021

Patients experience various biomechanical changes following reconstruction for anterior cruciate ligament (ACL) injury. However, previous studies have focused on lower extremity joints as a single joint rather than simultaneous lower extremity movements. Therefore, this study aimed to determine the movement changes in the lower limb coordination patterns according to movement type following ACL reconstruction. Twenty-one post ACL reconstruction patients (AG) and an equal number of healthy adults (CG) participated in this study. They were asked to perform walking, running, and cutting maneuvers. The continuous relative phase and variability were calculated to examine the coordination pattern. During running and cutting at 30 and 60°, the AG demonstrated a lower in-phase hip–knee coordination pattern in the sagittal plane. The AG demonstrated low hip–knee variability in the sagittal plane during cutting at 60°. The low in-phase coordination pattern can burden the knee by generating unnatural movements following muscle contraction in the opposite direction. Based on the results, it would be useful to identify the problem and provide the fundamental evidence for the optimal timing of return-to-sport after ACL reconstruction (ACLR) rehabilitation, if the coordination variable is measured with various sensors promptly in the sports field to evaluate the coordination of human movement.

Published: January 2021

Face recognition is a technology with great potential in the field of robotics, due to its prominent role in human-robot interaction (HRI). This interaction is a keystone for the successful deployment of robots in areas requiring a customized assistance like education and healthcare, or assisting humans in everyday tasks. These unconstrained environments present additional difficulties for face recognition, extreme head pose variability being one of the most challenging. In this paper, we address this issue and make a fourfold contribution. First, it has been designed a tool for gathering an uniform distribution of head pose images from a person, which has been used to collect a new dataset of faces, both presented in this work. Then, the dataset has served as a testbed for analyzing the detrimental effects this problem has on a number of state-of-the-art methods, showing their decreased effectiveness outside a limited range of poses. Finally, we propose an optimization method to mitigate said negative effects by considering key pose samples in the recognition system’s set of known faces. The conducted experiments demonstrate that this optimized set of poses significantly improves the performance of a state-of-the-art, cutting-edge system based on Multitask Cascaded Convolutional Neural Networks (MTCNNs) and ArcFace.
Serial MTJ-Based TMR Sensors in Bridge Configuration for Detection of Fractured Steel Bar in Magnetic Flux Leakage Testing
Authors: Jin Zhenhu , Mohd Noor Sam Muhamad Arif Ihsan , Oogane Mikihiko , Ando Yasuo
Published: January 2021

Thanks to high sensitivity, excellent scalability, and low power consumption, magnetic tunnel junction (MTJ)-based tunnel magnetoresistance (TMR) sensors have been widely implemented in various industrial fields. In nondestructive magnetic flux leakage testing, the magnetic sensor plays a significant role in the detection results. As highly sensitive sensors, integrated MTJs can suppress frequency-dependent noise and thereby decrease detectivity; therefore, serial MTJ-based sensors allow for the design of high-performance sensors to measure variations in magnetic fields. In the present work, we fabricated serial MTJ-based TMR sensors and connected them to a full Wheatstone bridge circuit. Because noise power can be suppressed by using bridge configuration, the TMR sensor with Wheatstone bridge configuration showed low noise spectral density (0.19 μV/Hz0.5) and excellent detectivity (5.29 × 10−8 Oe/Hz0.5) at a frequency of 1 Hz. Furthermore, in magnetic flux leakage testing, compared with one TMR sensor, the Wheatstone bridge TMR sensors provided a higher signal-to-noise ratio for inspection of a steel bar. The one TMR sensor system could provide a high defect signal due to its high sensitivity at low lift-off (4 cm). However, as a result of its excellent detectivity, the full Wheatstone bridge-based TMR sensor detected the defect even at high lift-off (20 cm). This suggests that the developed TMR sensor provides excellent detectivity, detecting weak field changes in magnetic flux leakage testing.
Analyse spectrale directe des minéraux
Authors: Gramont Arnaud de
Published: January 2021

Un grand nombre de minéraux métallifères, dont une partie seulement ont fait l’objet de ce travail, peuvent donner, avec l’étincelle de la bobine de Rhumkorff et du condensateur, de bons spectres de lignes brillantes.

Non seulement les métaux, mais aussi les métalloïdes donnent leurs raies dans l’étincelle condensée.

Les éléments contenus en faibles quantités sont facilement discernables par ce procédé.

Plusieurs corps, et notamment le fer, donnent dans ces conditions des raies qui n’avaient jusqu’ici été observées que dans l’arc électrique.

En supprimant le condensateur, les spectres des métalloïdes disparaissent, et ceux des métaux se réduisent aux raies les plus brillantes.

Les minéraux non conducteurs, mais volatilisables dans l’étincelle, fournissent également de bons résultats par cette méthode.

Les sels fondus que j’ai eu l’occasion d’étudier donnent avec l'étincelle condensée des spectres élémentaires, où les raies des métalloïdes sont brillantes et facilement discernables, comme celles des métaux.

Dans l’étude des spectres de comparaison, destinés à préciser les raies des éléments visibles dans les conditions où j’opérais, j’ai repris avec une plus grande approximation, notamment pour le soufre et le sélénium, les mesures qui avaient été faites antérieurement. Pour les autres métalloïdes et pour les métaux j’ai mesuré directement des raies qui n’avaient pas été signalées par les différents expérimentateurs, depuis MM. Plücker et Hittorf, ou Huggins. Ceux-ci les avaient, ou figurées seulement dans leurs planches, ou calculées dans une unité arbitraire.

Pour le soufre, enfin, j’ai montré qu’on pouvait obtenir facilement son spectre de lignes à l'air libre et dans les conditions ordinaires de température et de pression, sans recourir aux tubes de Plücker ou aux tubes à gaines.

Neste trabalho objetivou-se, avaliar a modelagem de efeitos mistos para estimativa do volume de eucalipto em sistema de integração Lavoura-Pecuária-Floresta (iLPF). Os dados foram coletados em uma área experimental de iLPF, implantada pela Empresa Brasileira de Pesquisa Agropecuária-EMBRAPA Agrossilvipastoril, localizada no município de Sinop, estado do Mato Grosso. Para alcançar os objetivos proposto, 186 árvores com 51 meses de idade foram cubadas para a modelagem do volume com regressão não linear tradicional (RT) e modelagem de efeitos mistos (MEM). O desempenho da modelagem foi avaliado por meio de indicadores estatísticos e análise gráfica. As duas técnicas avaliadas apresentaram resultados semelhantes com um pequeno ganho em precisão pela MEM. Desta forma, a MEM apresenta grande potencial de utilização em modelagem florestal, uma vez que apresenta maior acurácia de ajuste para estimativa do volume de eucalipto em integração Lavoura-Pecuária-Floresta.

Conceptual design of automated control systems (ACS) is an important stage in their development and creation. The miscalculations made here, as a rule, cannot be compensated in the subsequent project stages. Despite this, at the moment there is no sufficiently developed theory of conceptual design of promising ACS. As a rule, when forming the concept (control space) of a new ACS, either use a proto-type, or fundamentally new conceptual solutions are developed. The paper presents an attempt to develop a methodology for the conceptual design of an automated control system, which expands the designer’s creative capabilities, streamlining his reasoning and reducing the dimension of the synthesis problem. A template is proposed for creating a parametric concept of ACS with its subsequent detailing through the use of the categorical analysis method. The method is demonstrated on the development example of ACS concept by a group of unmanned aerial vehicles (UAV). A constructive scheme of management information, including data groups and relationships between them is considered. Data groups are formed taking into account the multidimensionality of the management process, where aspects (points of view) are generated using the categorical analysis apparatus. The interpretation of 32 categorical subsets is proposed, revealing 32 aspects of the UAV groups usage. On the example of the UAV functioning aspect, concerning the fire and electronic suppression of the enemy’s air defense, performed as an element of combat support for the process of solving the main tasks, the data on the state of the UAV group was detailed. For the formed metric system, groups of information transformation procedures are defined. It is advisable to use the presented results to create adaptive polyaspect special software for ACS by a UAV group.

Damage to the liver is a common clinical consequence of chronic diabetes mellitus type 2 (DM2). This study evaluates whether ultrasound shear wave elastography and hemodynamics of the portal vein and the hepatic artery can complement traditional clinical work-up data for the monitoring of liver health among DM2 patients.
Methods: Sixty-four (64) participants (31 controls and 33 patients with confirmed type 2 diabetes mellitus) between 21 to 74 years of age were recruited. Liver size, stiffness and hemodynamics of the portal vein and the hepatic artery were evaluated. Glycated hemoglobin (HbA1c), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) were monitored. Student’s t-test was employed with significance attained at p <0.05.
Results: Asymptomatic significant differences were detected among DMT2 patients: (1) Largest Liver size (p=0.04); (2) Higher liver stiffness (p=0.04); (3) Higher alkaline phosphate levels (p=0.03); (4) Higher HbA1c levels (<0.001) and (7) presence of moderate to severe liver fibrosis. DM2 F1 stage has higher liver stiffness (0.006) and HbA1c levels (<0.001).

Published: January 2021

We report an uncommon case of bilateral impending central retinal vein occlusion (CRVO) in a young girl with newly diagnosed chronic myeloid leukaemia (CML) and its successful reversal with leukapheresis. A young girl presented with vomiting and fever. Examination revealed hepatosplenomegaly and multiple enlarged lymph nodes. Investigations show severe hyperleukocytosis and anaemia. Bone marrow aspirate and trephine biopsy confirmed CML in the chronic phase. She was promptly referred to the ophthalmology team for assessment of vasculopathy. Bilateral fundus showed swollen and hyperaemic optic discs. There were dilated and tortuous retinal venules with perivascular white cell extravasation, scattered intraretinal haemorrhages, and Roth spots at mid-periphery. She received four cycles of leukapheresis and, consequently, her leukocytes reduced dramatically with associated significant improvement in fundus findings.

This case highlights uncommon impending CRVO in a young girl and the dramatic improvement in fundus signs following leukapheresis that halted and reversed the progression of impending CRVO.

Published: January 2021

Thirty-six strains of phosphate-solubilizing bacteria (PSB) isolated from the rhizosphere and rhizoplane of corn (Zea mays L.) crops in different states of México were subjected to phenotypic and genotypic characterization. The phosphate-solubilizing activity of each strain was first evaluated using tricalcium phosphate as the phosphorus source in the NBRIP-BPB culture medium. Phosphatesolubilizing capacity was also evaluated by adding the pH buffering agent MES (2-[Morpholine] ethanosulfonic acid) to the growth medium. Amplified ribosomal RNA restriction pattern analysis (ARDRA) was used to evaluate the genetic diversity. From the data matrix obtained, a dendrogram was built using the UPGMA method. The 16S rRNA gene of the BUAP29, BUAP36 and CP08 strains was amplified, cloned and sequenced for taxonomic identification. The 36 bacterial strains exhibited different levels of tricalcium phosphate solubilizing activity. Only BUAP33, BUAP17 and BUAP21 strains did not show the typical solubilization halo when the MES buffering agent was added to the growth medium. The analysis of ARDRA patterns as well as the dendrogram exhibited a large genetic diversity among the 36 PSB analyzed, with BUAP36 and BUAP15 strains showing 100 % similarity. The 16S rRNA gene sequence alignment of CP08, BUAP29 and BUAP36 strains showed 99 % identity with the sequences of Advenella incenata strain R-16599 (NCBI accession number AY569458.1), Burkholderia sp (NCBI accession number AY353696) and Burkholderia gladioli strain 223-1 (NCBI accession number DQ355168.1), respectively. In this study the A. incenata strain is reported as a PSB for the first time.

En este trabajo se analizó la expresión fenotípica y genotípica de 90 cruzas simples directas (A x B) de maíz (Zea mays L.) formadas por el apareamiento de 10 líneas del Grupo Enano (A) con nueve líneas normales (B) QPM (Quality Protein Maize), más las 90 cruzas recíprocas (B x A). Las cruzas se evaluaron en tres ambientes contrastantes en 2004. Se utilizó el promedio de altura de planta (cm) y rendimiento de mazorca (t ha-1) a través de localidades para analizar la expresión de las cruzas, y estimar la aptitud combinatoria de líneas y cruzas en las combinaciones A x B y B x A. Se encontraron diferencias (P ≤ 0.01) entre cruzas, así como en los componentes de los grupos A x B y B x A, en las líneas, probadores y la interacción líneas x probador dentro de cada grupo, para las dos variables en estudio, así como en el contraste entre los grupos A x B vs. B x A. Esto indica la variabilidad de las líneas en cada grupo, la importancia de su interacción y la diferencia ente los efectos directos y recíprocos en cruzas. La expresión de las cruzas entre líneas de los dos grupos germoplásmicos estuvo determinada por efectos aditivos de las líneas QPM, principalmente con 70.2 y 61.5 % de la variación en altura de planta y rendimiento de mazorca, respectivamente. Al combinar líneas entre estos dos grupos germoplásmicos no emparentados genéticamente, cambió el orden de participación de los progenitores y determinó diferencias en la expresión fenotípica, y en la estimación de los efectos genéticos de las líneas y sus cruzas. El orden de cruzamiento modificó los valores estimados de aptitud combinatoria general en el Grupo Enano y los efectos no-aditivos de los dos grupos de líneas, ya que en la aptitud combinatoria específica se obtuvieron correlaciones del orden de rs = 0.184 y rs = 0.252* para altura de planta y rendimiento de mazorca.

El estado de Nuevo León en México es centro de origen de Persea americana Mill. spp. drymifolia, como lo evidencian los vestigios de frutos encontrados en cuevas de la Sierra Madre Oriental. En este estado aún es posible encontrar plantas creciendo en hábitat silvestre y con características contrastantes a las de las variedades nativas que se cultivan en huertas familiares y de traspatio. Esta diversidad representa una fuente valiosa de genes y combinaciones genéticas que puede utilizarse en programas de mejoramiento de Persea. Debido a que esta diversidad genética no se ha caracterizado, se planteó su estimación en 42 árboles de aguacate nativo con base en características de peso, longitud y diámetro de fruto, peso, longitud y diámetro de semilla y, longitud y diámetro de la cavidad de la semilla, además de las relaciones longitud/diámetro de fruto y peso de semilla/peso de fruto. De éstas, sólo los pesos de semilla y fruto, y las longitudes de cavidad de semilla y de fruto fueron clasificatorios para la especie. Los resultados hicieron evidente que la clasificación de la diversidad con estos caracteres morfológicos de frutos no quedó bien representada. Para evaluar de forma directa la diversidad genética, se generaron AFLP que permitieron diferenciar cinco variedades en el análisis de agrupamiento; el no agrupamiento de variedades denominadas con el mismo nombre local permitió detectar diferencias genéticas dentro de variedades de la raza mexicana. Cuando los datos moleculares se analizaron en forma conjunta con los datos morfológicos, se logró diferenciar once variedades, y se repitió el esquema de no agrupamiento de variedades con el mismo nombre local. La utilidad de los AFLP en el análisis de diversidad genética entre variedades de P. americana de la raza mexicana quedó evidenciada con estos resultados.

Con el fin de cuantificar a Escherichia coli y determinar la presencia de Salmonella, se tomaron y analizaron 51 muestras de agua y 23 muestras de suelo en cuatro regiones del Valle de Culiacán, Sinaloa, México. Además, se determinó el perfil de resistencia de Salmonella a ampicilina, ciprofloxacino, trimetoprim-sulfametoxazol, tetraciclina, estreptomicina y gentamicina, y de los últimos tres antimicrobianos en E. coli. En las muestras de suelo analizadas hubo ausencia de E. coli y Salmonella, mientras que en las de agua se logró aislar 20 cepas de Salmonella. La serotipificación mostró que 13 cepas de Salmonella fueron Typhimurium, 2 de Infantis, 1 de Anatum, 1 de Agona, 1 de Oranienburg, 1 de Minnesota y 1 de Give. De las muestras de agua analizadas 98 % estaban contaminadas con E. coli, con mínimos de 4 UFC/100 mL, máximos de 4.5 x 105 UFC/100 mL y un promedio de 1.6 x 104 UFC/100 mL, de las cuales se seleccionaron cepas para evaluar el perfil de resistencia a antimicrobianos. Todas las cepas de Salmonella fueron susceptibles a ampicilina, ciprofloxacino y trimetoprim-sulfametoxazol y 12 presentaron resistencia a tetraciclina. De las 46 cepas de E. coli analizadas, nueve fueron resistentes a tetraciclina, 38 fueron resistentes a estreptomicina y sólo una cepa fue resistente a gentamicina; mientras que 23 cepas presentaron resistencia intermedia. Todas las cepas de Salmonella tuvieron altos niveles de resistencia a CuSO4•5H2O en dosis entre 1200 y 1600 µg mL-1 del antimicrobiano. El presente estudio demostró la existencia de diversos serotipos de Salmonella y altos niveles de E. coli en agua del Valle de Culiacán.

En el Estado de San Luis Potosí el principal problema para la producción de granos es la poca disponibilidad de agua de riego y las lluvias escasas e irregulares, por lo que se requieren cultivos alternativos que se ajusten a la escaza humedad disponible. El objetivo de esta investigación fue determinar la adaptación y estabilidad del rendimiento de tres híbridos enanos y cuatro variedades de porte normal de mijo perla (Pennisetum americanum L. Leeke). La evaluación se desarrolló en seis ambientes de riego y cinco de temporal o secano en el Altiplano, la Zona Media y la Planicie Huasteca del Estado de San Luis Potosí, ubicados a 1880, 1000 y 40 msnm, respectivamente, durante 2006 y 2007. Los genotipos se establecieron en un diseño de bloques completos al azar con tres repeticiones en cada ambiente. Se registró el rendimiento de grano, días a madurez, altura de planta, excersión, índice de cosecha, número de semillas por panícula y peso de semilla. Mediante el método de Eberhart y Russell se estimaron los parámetros de estabilidad bi y S2di. En condiciones de riego, la Zona Media fue el mejor ambiente de producción, seguida de la Planicie Huasteca y el Altiplano; mientras que en temporal el mejor ambiente fue la Planicie Huasteca, seguida de la Zona Media y Altiplano. Los híbridos mostraron mayor estabilidad de rendimiento que las variedades en ambientes de riego; en contraste en temporal las variedades fueron más estables que los híbridos. La variedad ‘ICMV-93191’ y el híbrido precoz ‘68AI x 086R’ mostraron buena estabilidad de rendimiento en ambientes desfavorables, por lo que representan alternativas viables para reducir las pérdidas de cosechas en las regiones semiáridas del estado.

Published: January 2021

Lupinus elegans Kunth is a common species in the West-Central region of México. L. elegans has been used for the restoration of degraded conifer forests because it creates microenvironments suitable for the establishment of coniferous species by increasing nitrogen concentrations in the soil. In this study we determined the genetic variation of L. elegans populations using RAPD markers. One hundred and fifty individuals were collected from five populations in Michoacán: Llano de Pario, Charapan, Pico de Tancítaro, San Nicolás and Villa Madero. Results indicate genetic variation (h) about 0.20 with 60 % polymorphism. The molecular analysis showed higher genetic variation within (59 %) than between (41 %) populations. A Neighbor Joining tree was generated based on Nei's genetic distances, and the resulting tree clustered the populations of Llano de Pario and San Nicolás, followed by populations of Tancítaro, and lastly clustered Villa Madero and Charapan. No correlation was found between genetic and geographic distances. Common garden experiments indicate that plants from the local population out perform introduced plants. These results suggest that although L. elegans is a species with a considerable geographic range, seed collection for restoration purposes should be done from the closest (geographical)population possible.

A partir de un estudio de 120 poblaciones de maíz (Zea mays L.) nativas del Istmo de Tehuantepec, Oaxaca, México, previamente caracterizadas morfológicamente, se seleccionaron 40 poblaciones representativas para analizar su diversidad genética mediante polimorfismos de 19 loci de isoenzimas. Las 40 poblaciones correspondieron a dos grupos; el primero, integrado por 21 poblaciones de maíz de la raza Zapalote Chico; y el segundo, por 19 poblaciones conocidas localmente como Maíz Grande. Ambos grupos fueron a su vez subdivididos en tres subgrupos cada uno identificados como precoz, intermedio y tardío. Los estimadores de la diversidad genética mostraron valores altos para el grupo de poblaciones de Maíz Grande, con mayor número de alelos por locus, polimorfismo y heterocigosidad esperada, así como una diferenciación genética entre sus poblaciones mayor que la de Zapalote Chico. En Zapalote Chico se observó que el subgrupo tardío presentó los valores más bajos para los estimadores de diversidad genética y de diferenciación genética entre sus poblaciones, mientras que en el subgrupo intermedio tales valores fueron altos. Entre los tres subgrupos de Maíz Grande el subgrupo precoz presentó los valores más bajos diversidad y de diferenciación genética entre sus poblaciones, mientras que el tardío tuvo un mayor número de alelos por locus, y el intermedio presentó los valores más altos para polimorfismo, heterocigosidad esperada y una mayor diferenciación genética entre sus poblaciones.

Se analizó la sobrevivencia de Salmonella typhimurium sola y asociada con Rhizopus sp. en frutos de melón 'Cantaloupe' (Cucumis melo L.) var. reticulatus durante el almacenamiento en frío con atmósferas controladas (AC). Frutos de tamaño uniforme se inocularon con 8.2 log10 UFC de una cepa de S. typhimurium ATCC2356, resistente a kanamicina (Km), y se almacenaron en las atmósferas: AC1 con O2 3 %, CO2 12 % y N2 85 %; AC2 con O2 5 %, CO2 15 % y N2 80 %; y aire con O2 20.95 %, CO2 0.03 % y N2 78.08 %, a 3.7 ºC y humedad relativa (HR) de 93.6 ± 5.9 % por 192 h. Cada 48 h se extrajo un fruto en el que se tomaron muestras de tejido inoculado para pruebas de detección en agar entérico Hektoen con Km (50 μg mL-1). Los resultados mostraron que S. typhimurium puede sobrevivir en la superficie del fruto en las atmosferas refrigeradas AC1, AC2 y aire; sin embargo, bajo estas condiciones la población bacteriana registró un decremento (P ≤ 0.05) de 3.7, 4.3 y 4.75 log10 UFC por fruto, respectivamente. La presencia de Rhizopus sp. no afectó la capacidad de sobrevivir de la bacteria ni el nivel de su población en AC2 y aire en condiciones similares de temperatura y HR. Se evidencia así la capacidad de S. typhimurium para sobrevivir en atmósferas con alta concentración de CO2 y condiciones adversas de temperatura, así como de la importancia de prevenir la contaminación del melón 'Cantaloupe' durante su producción y comercialización.
PROCEDIMIENTO PARA EL ANÁLISIS DE EQUILIBRIO PARCIAL DE LAS EXPORTACIONES MEXICANAS DE MANGO (Mangifera indica) A EE. UU.

EE. UU. es el principal importador de mango (Mangifera indica L.) en el mundo, y México es su principal proveedor. La participación de México en las importaciones de mango en el mercado estadounidense ha disminuido, al tiempo que Perú, Brasil y Ecuador han aumentado su participación. Aquí se analiza el mercado internacional de mango entre EE. UU. y México con un modelo de ecuaciones simultáneas. Se simula un incremento de las exportaciones de mango de 20 %, suficiente para causar un decremento en el precio interno de EE. UU. Los resultados muestran que dicho descenso en precio puede ser acomodado por un incremento en ingreso; cuando se considera un incremento en costo por la mayor producción, la relación beneficio costo resulta mayor que la unidad.
اعمال السيادة في ظل التطور التشريعي والقضائي في النظم المقارنة

Acts of sovereignty means a group of acts performed by the executive authority, and shall not be subjected to the Judicial review by cancelation or compensation.

    Therefore, the acts of sovereignty - in such situation - considered to be out of legitimacy, and have been subjected to a great criticism by the French jurisprudence and then the Egyptian jurisprudence on the bias that the executive authority may employ the idea of acts of sovereignty in its favor, by performing whatever acts in the form of sovereignty, that shall be sufficient to make such acts out of legitimacy and law rules, in such case the judiciary shall not have the right of cassation, or contestations against such acts nor the seeks of compensation because of the damages resulted by such acts. Hence the seriousness of this theory appears which was created by the French judiciary.

     The idea of acts of sovereignty has played an important role in the conflict of the state authorities, and highlighted the importance of the legitimacy principle, and the legality of the

state through theJurisprudential disagreements and discussions.

     Although that such theory was created in the French administrative judiciary, it could be found in other judicial systems of other countries such as Egypt and Iraq. And although the weakness of such theory, it could be alive until now, furthermore, it could have a power in many common legal systems. Because of the absence of the administrative judiciary in Iraq, the researchers could not practice such theory with its activities. As the second amendment law was issued of the law of council of state No.(106) in 1989, announcing the administrative judiciary by establishing a court (for the first time) in which the cassation in the trueness of the orders and decisions issued by the employees and administrative bodies shall be performed.
تراجع معيار جنسية المدعي عليه في مسائل الاحوال الشخصية
Authors: الامين خير الدين

شهدت الفترة الاخيرة في حياة القانون الدولي الخاص توسع اخذ بالازدياد في مجال تبني ضابط الإرادة في علاقات الاحوال الشخصية, حيث يسمح القانون الدولي الخاص المعاصر للأطراف، في بعض الاحيان ، باختيار القانون الواجب التطبيق على علاقاتهم الشخصية. وهذا التوجه بدأ العمل به على الصعيدين: التشريعات الوطنية المقارنة والاتفاقيات الدولية, والمثال بالنسبة للتشريعات الوطنية, القانون الدولي الخاص البلجيكي لعام 2004 ومجموعة اخرى من قوانين دول امريكا الشمالية وكذلك القانون الالماني, حيث تم الاعتراف بضابط الإرادة في مسائل الاحوال الشخصية والإرث في مجال تحديد القانون الواجب التطبيق , اما على صعيد الاتفاقيات الدولية, فقد لاحظنا ان لائحة روما الثالثة تمثل مرحلة مهمة لتراجع معيار الجنسية امام معيار قانون الارادة, حيث بات هذا المعيار هو من يحدد كيفية الوصول الى الاحكام الموضوعية في القانون الواجب التطبيق.

 اما بالنسبة للهدف المباشر من معالجة هذا الموضوع, هو معرفة مدى امكانية تعديل المادة 19 من القانون المدني العراقي النافذ, وذلك بمنح الأطراف امكانية تحديد القانون الواجب التطبيق على منازعاتهم مع الاخذ بنظر الاعتبار بعض المحددات المعروفة في القانون الدولي الخاص, من مثل فكرة النظام العام ونظرية الغش نحو القانون وغيرها.
المعلومة الداخلية للشركة المساهمة وموقف التشريع العراقي والتشريعات المقارنة من حظر افشائها

هناك القليل من الأشخاص على اطلاع على المعلومات الداخلية للشركة ، وذلك من خلال المركزالوظيفي الذي يشغلونه في تلك الشركة ، أو قد يكون من خلال ارتباطهم بعلاقات مع أشخاص مطلعين عليها.

    فاذا تمت عملية بيع الأسهم أو شرائها بناءا على تلك المعلومات والتي كان المركز الوظيفي للمطلع او علاقاته مع مطلعين عليها سبباً في الحصول عليها ومما سيؤديه ذلك من جمع أرباح على حساب أشخاص ليس لديهم اطلاع على تلك المعلومات سيعمل ذلك كله إلى انتهاك العدالة في السوق المالي، حيث ان عدم حصول شخص اخر على تلك المعلومات لم يكن عائداً إلى قله مقدار الجهد المبذول من قبله لمعرفة مدى تأثير هذه المعلومات في أسعار الأسهم،او قلة خبرته في السوق المالي  وإنما يعود الى وظيفة ومنصب المطلع او علاقته بمطلعين على المعلومات الداخلية  الأمر الذي يقوض الثقة بسوق الأوراق المالية، وهذا ينعكس بدوره الى  إحجام أشخاص كثيرين عن الاستثمار في الأسهم، والتخبط في النمو الاقتصادي.

Баарыбызга маалым болгондой аркылуу мамиле этишке мүнөздүү категория. Мамиле категорияларынын эӊ негизги өзгөчөлүгү - кыймыл-аракеттин субъектиси менен объектисинин ортосундагы мамиле, б.а. сүйлөмдө ээлик милдет аткарган сөздүн же кыймыл-аракеттин чыныгы аткаруучусунун субъект же объект экендигин аныктайт. Алардын ичинен аркылуу мамиле кыймыл-аракеттин башка бирөө тарабынан иштелгенин билдирет. Биз бул эмгегибизде кыргыз тилиндеги мамиле категорияларынан -

Категория залога - есть необходимая категория языковой мысли, присущая общению. Важнейшей особенностью категорий залога является отношение между субъектом и объектом действия. В
предложении данная категория определяет, является ли реальный исполнитель слова или действия, выполняющий функцию, субъектом или объектом, и означает ли что действие было разработано кем-то другим. В этой статье мы проанализируем категорию залога с исторической и семантической точек зрения в кыргызском языке. Определяя значения, мы будем анализировать историю этих залогов от древнего Коктюрского времени до наших дней и подробно обсуждать лингвистические методы, с помощью которых они сформированы. Наша статья основана на материале кыргызского и турецкого языков.
The collateral category is a necessary category of linguistic
thought inherent in communication. The most important feature of the categories of collateral is the relationship between the subject and the object of the
action. In a sentence, this category determines whether the real performer of a word
or action performing a function is a subject or an object, and means that the
action was designed by someone else. In this article, we will analyze the category of collateral from a historical and semantic point of view in the Kyrgyz language. By defining the meanings, we will analyze the history of these pledges from ancient Cocturian times to the present day and discuss in detail the linguistic methods by which they were formed. Our article is based on the material of the Kyrgyz and Turkish languages.

Понятие "воспитание" - одно из ведущих в педагогике. Оно употребляется в широком и в узком смыслах. Воспитание в широком смысле рассматривается как общественное явление, как воздействие общества на личность. В данном случае воспитание практически отождествляется с социализацией. Воспитание в узком смысле рассматривается как специально организованная деятельность педагогов и воспитанников по реализации целей образования в условиях педагогического процесса. Деятельность педагогов в этом случае называется воспитательной работой. В статье говорится, что «национальные требования и новаторские качества”, являющиеся источниками содержания воспитательной работы, важны для того, чтобы в будущем учащиеся стали патриотами страны, а также для использования в школах образовательной системы гуманистического образования.
The concept of "education" is one of the leading in pedagogy. It is used in a broad and narrow sense. Education in a broad sense is viewed as a social phenomenon, as the impact of society on the individual. In this case, education is practically equated with socialization. Upbringing in a narrow sense is considered as a specially organized activity of teachers and pupils to realize the goals of education in the conditions of the pedagogical process. The activity of teachers in this case is called educational work.
The article says that “ethnopedagogy and innovative qualities”, which are
the sources of the content of educational work, are important for future students
to become patriots of the country, as well as for use in schools of the educational
system of humanistic education.
