Published: June 2019

Land surface deformation in metropolitan areas, which can cause varying degrees of hazard to both human lives and to properties, has been documented for decades in cities worldwide. Xuzhou, is one of the most important energy and industrial bases in eastern China, and has experienced significant land subsidence due to both excessive extraction of karst underground water and exploitation of mineral resources in recent decades. Furthermore, Xuzhou has recently undergone rapid urbanization in terms of urban expansion and underground construction, which could induce additional pressure on the urban land surface. However, most previous research on land surface deformation in the Xuzhou urban areas has been conducted based on traditional ground-based deformation monitoring techniques with sparse measurements. Little is known about the regional spatiotemporal behavior of land surface displacement in Xuzhou. In this study, a detailed interferometric synthetic aperture radar (InSAR) time series analysis was performed to characterize the spatial pattern and temporal evolution of land surface deformation in central areas of Xuzhou during 2015–2018. A method based on principal component analysis was adopted to correct artifacts in the InSAR signal. Results showed the correction strategy markedly reduced the discrepancy between global navigation satellite systems and InSAR measurements. Noticeable land subsidence (−5 to −41 mm/yr) was revealed widely within the Xuzhou urban areas, particularly along subway lines under construction, newly developed districts, and in old coal goafs. Remarkable consistent land uplift (up to +25 mm/yr) was found to have significantly affected two long narrow areas within the old goafs since 2015. The possible principal influencing factors contributing to the land surface displacements such as subway tunneling, building construction, mining, underground water levels and geological conditions are then discussed.

Published: June 2019

Wearable technology can be employed to elevate the abilities of humans to perform demanding and complex tasks more efficiently. Armbands capable of surface electromyography (sEMG) are attractive and noninvasive devices from which human intent can be derived by leveraging machine learning. However, the sEMG acquisition systems currently available tend to be prohibitively costly for personal use or sacrifice wearability or signal quality to be more affordable. This work introduces the 3DC Armband designed by the Biomedical Microsystems Laboratory in Laval University; a wireless, 10-channel, 1000 sps, dry-electrode, low-cost (∼150 USD) myoelectric armband that also includes a 9-axis inertial measurement unit. The proposed system is compared with the Myo Armband by Thalmic Labs, one of the most popular sEMG acquisition systems. The comparison is made by employing a new offline dataset featuring 22 able-bodied participants performing eleven hand/wrist gestures while wearing the two armbands simultaneously. The 3DC Armband systematically and significantly ( p < 0.05 ) outperforms the Myo Armband, with three different classifiers employing three different input modalities when using ten seconds or more of training data per gesture. This new dataset, alongside the source code, Altium project and 3-D models are made readily available for download within a Github repository.

Authors: Yang Jing , Sun Yizhong , Shang Bowen , Wang Lei , Zhu Jie
Published: June 2019

With the availability of large geospatial datasets, the study of collective human mobility spatiotemporal patterns provides a new way to explore urban spatial environments from the perspective of residents. In this paper, we constructed a classification model for mobility patterns that is suitable for taxi OD (Origin-Destination) point data, and it is comprised of three parts. First, a new aggregate unit, which uses a road intersection as the constraint condition, is designed for the analysis of the taxi OD point data. Second, the time series similarity measurement is improved by adding a normalization procedure and time windows to address the particular characteristics of the taxi time series data. Finally, the DBSCAN algorithm is used to classify the time series into different mobility patterns based on a proximity index that is calculated using the improved similarity measurement. In addition, we used the random forest algorithm to establish a correlation model between the mobility patterns and the regional functional characteristics. Based on the taxi OD point data from Nanjing, we delimited seven mobility patterns and illustrated that the regional functions have obvious driving effects on these mobility patterns. These findings are applicable to urban planning, traffic management and planning, and land use analyses in the future.

Published: June 2019

Falls are the major cause of fatal and non-fatal injury among people aged more than 65 years. Due to the grave consequences of the occurrence of falls, it is necessary to conduct thorough research on falls. This paper presents a method for the study of fall detection using surface electromyography (sEMG) based on an improved dual parallel channels convolutional neural network (IDPC-CNN). The proposed IDPC-CNN model is designed to identify falls from daily activities using the spectral features of sEMG. Firstly, the classification accuracy of time domain features and spectrograms are compared using linear discriminant analysis (LDA), k-nearest neighbor (KNN) and support vector machine (SVM). Results show that spectrograms provide a richer way to extract pattern information and better classification performance. Therefore, the spectrogram features of sEMG are selected as the input of IDPC-CNN to distinguish between daily activities and falls. Finally, The IDPC-CNN is compared with SVM and three different structure CNNs under the same conditions. Experimental results show that the proposed IDPC-CNN achieves 92.55% accuracy, 95.71% sensitivity and 91.7% specificity. Overall, The IDPC-CNN is more effective than the comparison in accuracy, efficiency, training and generalization.

Authors: Bukvic Anamaria
Published: June 2019

The cognitive dissonance between the need for relocation as an adaptation strategy and the reluctance to consider this option among stakeholders may result in maladaptation in communities highly vulnerable to coastal hazards. This study presents an interactive communication tool, Coastal Relocation Leaf (CRL), designed to facilitate an understanding of the circumstances that may lead to relocation. The tool is designed to allow users to explore “what-if” scenarios, fostering further conversation about the complexities and trade-offs associated with the possibility of relocation in coastal communities. The tool is visualized using the Adobe Flash platform and refined using expert evaluation.
ICT Implementation of Small- and Medium-Sized Construction Enterprises: Organizational Characteristics, Driving Forces, and Value Perceptions
Authors: Lu Hao , Pishdad-Bozorgi Pardis , Wang Guangbin , Xue Yingxia , Tan Dan
Published: June 2019

This study discusses the organizational characteristics, driving factors, and value perceptions of small- and medium-sized construction enterprises in information and communication technology (ICT) implementation and investigates how the heterogeneous impacts of these features on subsequent ICT implementation practices are manifested. Based on questionnaire responses provided by 338 respondents from the Chinese construction industry, these associations were empirically tested using statistical methods, such as t-test, ANOVA, and correlation test. The analysis results indicate that the engagement of small- and medium-sized enterprises (SMEs) in ICT is a function of their annual sales turnover and the location in which they are operating, but no correlation was found with age, ownership structure, or business type. Moreover, strategic orientation was found to be the most effective driver in determining SMEs’ ICT-level, followed by pressures from competitors, incentive and mandatory policies from the government, intentions to improve work efficiency and quality, and ICT requirements from clients and partners, in that order. The findings further reveal that the differences in value perceptions generated after the adoption of ICT is the reason why SMEs tend to adopt less expensive ICT, that is, to use packaged rather than customized ICT, which can improve efficiency quickly, without considering the long-term benefits of the selected ICT. These findings provide insights for researchers and policymakers, allowing them to develop an in-depth understanding of the stimuli that are advantageous in ICT implementation in construction SMEs in developing countries.

Authors: Chen Wen-Ching , Chiou Tai-Ying , Delgado Aileen L. , Liao Chien-Sen
Published: June 2019

The study aims to develop novel biofungicide formulations against rice blast disease. A total of 300 rhizobacteria strains were isolated from rice field soil and were examined for the inhibition of Magnaporthe oryzae growth in a vitro test. Among them, only six rhizobacteria showed inhibition against M. oryzae. The three strains that showed the highest inhibition were Bacillus subtilis 5, B. cereus 3S5, and Pseudomonas fluorecens 10S2. A rice hull mixture and liquid medium were mixed with the above-mentioned bacterial suspensions into three bacterial formulas and tested separately on the rice cultivar UPLRi-5 after infection by M. oryzae under a controlled condition. The three novel biofungicide formulas significantly inhibited rice blast disease intensity with a mean disease control rate being approximately 31% higher than the control. The formulas proved to be effective and should be considered as promising novel treatments for rice blast disease.
A System Dynamics-Based Approach to Help Understand the Role of Food and Biodegradable Waste Management in Respect of Municipal Waste Management Systems
Authors: Babalola Micky A.
Published: June 2019

The long-term plan of any city in Japan is to become a material recycling society. The use of all types of municipal waste is essential in maximizing the full potential of material recovery. As such, municipalities are responsible for managing their waste, including food and biodegradable waste (FBW), and this results in some complex schemes. This study uses the system dynamics approach to illustrate and investigate the benefits of separate treatment of FBW. At the same time, to understand the dynamic interactions between all aspects and elements of the current municipal solid waste management system in Oita City. The developed model includes total environmental benefit, motivation to manage waste and resources, and yield from treatment facilities. The result shows that with the introduction of an anaerobic digester (AD) plant for FBW increases the efficiency of incineration. Furthermore, the result indicates that strengthening the regulation of waste sorted and the reduction in the amount of FBW treated in incineration will improve the current system. This study concludes that any policy or regulation less than the proposed result will yield less benefit. Thus, strengthening regulation is a crucial part of the sustainability of FBW management in the long run.

Sulfation–Roasting–Leaching–Precipitation Processes for Selective Recovery of Erbium from Bottom Ash
Authors: Ponou Josiane , Garrouste Marisol , Dodbiba Gjergj , Fujita Toyohisa , Ahn Ji-Whan
Published: June 2019

Bottom ash (BA) is mainly composed of compounds of Al, Fe, Ca, and traces of rare earth elements (REEs). In this study, the selective recovery of erbium (Er) as REEs by means of sulfation–roasting–leaching–precipitation (SRLP) using BA was investigated. A pre-treatment process of sulfation and roasting of BA was developed to selectively recover REEs using ammonium oxalate leaching (AOL) followed by precipitation. Most of the oxides were converted to their respective sulfates during sulfation. By roasting, unstable sulfates (mostly iron) decomposed into oxides, while the REE sulfates remained stable. Roasting above 600 °C induces the formation of oxy-sulfates that are almost insoluble during AOL. Dissolved REEs precipitate after 7 days at room temperature. The effects of particle size, roasting temperature, leaching time, and AOL concentration were the important parameters studied. The optimal conditions of +100–500 μm particles roasted at 500 °C were found to leach 36.15% of total REEs in 2 h 30 min and 94.24% of the leached REEs were recovered by precipitation. A total of 97.21% of Fe and 94.13% of Al could be separated from Er.
In a Search for Equity: Do Direct Payments under the Common Agricultural Policy Induce Convergence in the European Union?
Authors: Volkov Artiom , Balezentis Tomas , Morkunas Mangirdas , Streimikiene Dalia
Published: June 2019

The European Union (EU) is an integrated alliance of equally treated Member States sharing mutual values, legal principles and markets. Close cooperation, deep integration and convergence are the major priorities for the EU. Anyway, these principles are not always reflected in the EU-wide policies which are implemented through financial support mechanisms. The direct payments financial support mechanism under the Common Agricultural Policy, the main instrument for promoting convergence in development of Member States’ agricultural sectors and rural sustainability, faces critique for failing to meet its objectives. One of the major deficiencies of the direct payments scheme is that it allocates more resources to already developed agricultural sectors of the older Member States and less resources to developing ones thus increasing the divergence among the Member States. The aim of this paper is to suggest new mechanisms for direct payment funds redistribution across the EU Member States which are based on the methodological principles that would more precisely correspond to the aims of convergence, transparency and fair redistribution. The results show that, regardless of the method chosen (to support more or less effective agricultural sectors of EU Member States), the proposed methodology lowers differences in direct payment rates among the EU Member States by two-fold. This ensures correspondence to the goal of convergence within the EU.
Italy without Urban ‘Sprinkling’. A Uchronia for a Country that Needs a Retrofit of Its Urban and Landscape Planning
Authors: Romano Bernardino , Fiorini Lorena , Marucci Alessandro
Published: June 2019

The research presented in the work is linked to important production of data over 10 years of activity that allowed us to trace the configuration of Italian urban settlements in the 1950s. Starting from this information, the paper puts forward a uchronian reconstruction of the physiognomy of the national territory asking if—instead of the weak urban development policies implemented for over half a century—a more purposeful method of planning and designing settlements had been chosen in the Sixties to favor their aggregation and protect the country’s huge landscape heritage. From the model used, important indications emerge for control and management of retrofit (de-sprinkling) policies of which the need has been felt in recent years, as suggested by repeated messages from European bodies, the scientific community, associations and some politicians. The uchronic scenario is constructed starting from the settlement configuration of the 1950s, developing a model of maximum aggregation for the urbanized parts that were intervened in between this period and 2000, simulating a geography that maintains the quantities of soil transformed over the last 50 years. It emerges from the processing of the data that the Italian territory would have retained its low settlement density areas almost intact at the same level as in the 50s, that is to say 73% of the entire peninsular territory. It would also have preserved a large part of its free peninsular and insular coastline at about 60–70%, against the present day 45%.

Published: June 2019

Given a graph G = ( V , E ) , a function f : V → { 0 , 1 , 2 , ⋯ } is said to be a total dominating function if ∑ u ∈ N ( v ) f ( u ) > 0 for every v ∈ V , where N ( v ) denotes the open neighbourhood of v. Let V i = { x ∈ V : f ( x ) = i } . We say that a function f : V → { 0 , 1 , 2 } is a total weak Roman dominating function if f is a total dominating function and for every vertex v ∈ V 0 there exists u ∈ N ( v ) ∩ ( V 1 ∪ V 2 ) such that the function f ′ , defined by f ′ ( v ) = 1 , f ′ ( u ) = f ( u ) − 1 and f ′ ( x ) = f ( x ) whenever x ∈ V \ { u , v } , is a total dominating function as well. The weight of a function f is defined to be w ( f ) = ∑ v ∈ V f ( v ) . In this article, we introduce the study of the total weak Roman domination number of a graph G, denoted by γ t r ( G ) , which is defined to be the minimum weight among all total weak Roman dominating functions on G. We show the close relationship that exists between this novel parameter and other domination parameters of a graph. Furthermore, we obtain general bounds on γ t r ( G ) and, for some particular families of graphs, we obtain closed formulae. Finally, we show that the problem of computing the total weak Roman domination number of a graph is NP-hard.

One way to overcome it is to combine together several approaches such as molecular modeling and experimental structural biology techniques. Indeed, the interplay between structural and dynamical properties of the system is crucial to unravel the function of molecular machinery’s. In this review, we focus on how molecular simulations along with structural information can aid in interpreting biological data. Here, we examine two different cases: (i) the endosomal translocation toxins (diphtheria, tetanus, botulinum toxins) and (ii) the activation of adenylyl cyclase inside the cytoplasm (edema factor, CyA, ExoY).

Published: June 2019

Sn-Cu alloy powders were prepared via a simple chemical reduction method for the negative electrode materials in lithium-ion batteries. The addition of Cu can suppress the growth of Sn particles during synthetic process. Furthermore, the Cu also acts as a matrix phase against the volume change during cycling. With increasing amount of the Cu, a stable Cu6Sn5 phase formed in the Sn-Cu alloy and its cycle performance greatly enhanced depending on the Cu content. To promote the generation of the Cu6Sn5 phase, the synthesis temperature is raised to 60–100°C from the ambient temperature. The Sn-Cu alloy powders prepared at elevated temperatures showed remarkable cycle performances. The Sn-Cu alloy powder obtained at 60°C exhibited a significantly high volumetric capacity of over 2,000 mAh/cc at the 50th cycle.

Published: June 2019

The inhibition performance of sodium gluconate (SG), cetyltrimethylammonium bromide (CTAB) and their mixture (SG/CTAB) on the corrosion behavior of α-brass in 0.5 M H2SO4 solution has been investigated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), Scanning Electron Microscope with Energy-Dispersive Spectrometer (SEM-EDS), Inductively Coupled Plasma Spectrometry (ICPS) and molecular dynamics (MD) simulation techniques. The results reveal that SG with 5ppm CTAB, noted SG/CTAB, acts as a good corrosion inhibitor and its inhibition efficiency reached 89% after 24 h immersion in sulfuric acid solution, but slightly decreased at higher temperatures. The polarization curves displayed that SG/CTAB acts as a cathodic-kind inhibitor. Electrochemical impedance spectroscopy (EIS) studies revealed that the addition of 5ppm CTAB to different concentrations of SG considerably increases the corrosion resistance of α-brass. The SEM-EDS and ICPS analyses support the experimental results. Further, molecular dynamics (MD) simulations were used to understand the adsorption profiles of SG/CTAB on Cu(111) and Zn(111) surfaces.

Authors: Song Woo Jae , Choi Seung Geon , Lee Eun-Sang
Published: June 2019

Nitinol is an alloy of nickel and titanium. Nitinol is one of the shape memory alloys(SMA) that are restored to a remembered form, changing the crystal structure at a given temperature. Because of these unique features, it is used in medical devices, high precision sensors, and aerospace industries. However, the conventional method of mechanical machining for nitinol has problems of thermal and residual stress after processing. Therefore, the electrochemical machining(ECM), which does not produce residual stress and thermal deformation, has emerged as an alternative processing technique. In addition, to replace the existing experimental planning methods, this study used deep neural network(DNN), which is the basis for AI. This method was shown to be more useful than conventional method of design of experiments(RSM, Taguchi, Regression) by applying deep neural network(DNN) to electrochemical machining(ECM) and comparing root mean square errors(RMSE). Comparison with actual experimental values has shown that DNN is a more useful method than conventional method. (DOE - RSM, Taguchi, Regression). The result of the machining was accurately and efficiently predicted by applying electrochemical machining(ECM) and deep neural network(DNN) to the shape memory alloy(SMA), which is a hard-mechinability material.

Published: June 2019

The crystal structure of γ Cu₂ (OH)₂ CrO₄, the monoclinic form of copper hydroxy chromate, has been investigated by the « heavy atom » method. The refinement carried out by the least-squares method, leads to good agreement between calculated and observed structure factors (R = 0,10). In this structure the coordination polyhedron of copper is a deformed octahedron. The oxygen and OH form a distorted hexagonal close packing array in which Cu⁺⁺ and Cr[vi] partially fill the octehedral and tetrahedral sites. There are two cationic layers : in the first one the octahedral sites are half filled by Cu⁺⁺ ions, in the second one 1/4 of the octahedral sites are filled by Cu⁺⁺ and 1/8 of the tetrahedral sites by Cr[vi].

A study of the bonding shows perfect cohesion of the structure, which explains the great stability of this form, as opposed to the other metastable β form in which cohesion is very poor.

Published: June 2019

An X-ray study has been undertaken of a member of the arsenopyrite-glau-codot series with a composition (Co₀,₂₅ Fe₀,₇₅) AsS.

Weissenberg and precession photographs show that the crystal is monoclinic. The axes ' a ' and ' b ' are close to those of arsenopyrite, FeAsS, but ' c ' varies according to the Co-Fe ratio. The angle β is 90°.

The dispersion curves of the principal reflectivities of this strongly absorbing crystal have been determined by microreflectivity measurements of the three directions [001], [010] and [100] for 19 wavelengths. These reflectivities, in air, are around 50 %. The anisotropy is weak (~ 0.5 %) on the face (001) and could be taken to indicate uniaxial optical symmetry of the crystal. The optical parameters have been calculated for each wavelength and each orientation studied. The refractive indices ' n ' vary between 2.7 and 4.9. The absorption coefficients are close to 2.8 with only slight dispersion. The weak anisotropy of the face (001) is confirmed by its birefringence and biabsorption which are small for a strongly absorbing mineral.

The core of the crystal is zoned and the reflectivity R[001] increases slightly with increase in the Co content determined by electron microprobe point analysis. Finally, the Vickers microhardness varies between 730 and 1150 according to the orientation measured and the charge used.

Purpose of the study. Justification of the effective treatment tactics of the wounded with the gunshot fractures of the long bones.

Materials and methods. The examination and treatment of 123 wounded with gunshot fractures were performed. All wounded were divided into 3 groups according to clinical observation. For the first clinical group the traditional treatment of the combat fractures with osteometallosynthesis out of injury zone was done. In the second group, treatment was added with negative pressure therapy. In the third clinical group Wounded got a VAC-associated therapy with the proposed of counter-drainage of wounds with the flow-washing irrigation with antiseptic solutions Decasan + 3% hydrogen peroxide. A bacteriological study of the wounds` exudates was carried out, and the sensitivity of microorganisms to antibiotics was determined.

Results. The assay of microbiological investigation of the wounds of patients, which got explosive and mineexplosive injuries, demonstrated a predominance gramnegative microflora in the wound microbiocenoses such as Acinetobacter spp. (53% of cases) and Pseudomonas spp. (15% of cases). Gram-positive cocci were isolated from 22,2% of cases. The analysis of the antibiotic sensitivity data of gram-negative nonfermentative rods showed a high level of resistance to most antibacterial. All strains of acinetobacteria and pseudomonads were susceptible to polymyxin B and colistin, but resistant to unprotected and protected aminopenicillins (amoxicillin/clavulanate, ampicillin/ sulbactam). Acceleration of regenerative processes in the wound under the influence of VAC-therapy (formation of healthy granulations, disappearance of edema) in patients with negative pressure suppression (II HS, III HS) led to a reduction of hospitalization period, which took in average 7,8 ± 1,2 days, that was 5,2 ± 0,8 days less than in a control group. In the third group of wounded, a mixture of Decasan and 3% hydrogen peroxide in the proportion of 3 : 1 was used for rinsing of wounds. On the third day tissue edema decreased in 94,45% of the wounded in that observation group, while in the second clinical group it was observed in 88,89% of patients. The duration of the hydration phase in the wound process was reduced to 5,7 days. The period of complete healing of the wounds was shorter for 2,5 days. The period of indoor stay of the wounded of this group in the hospital decreased from 14,97 to 10,8 days.

Conclusions. Prevalence of gram-negative microorganisms in a gunshot wound and their high degree of resistance to antibiotics should be noticed when one takes a decision about empirical antibiotic therapy in the wounded. Observed clinical results of the proposed negative pressure therapy with counter-drainage of wounds by setting of flow-washing irrigation with a mixture of antiseptics Decasan and 3% hydrogen peroxide allow recommending this scheme for treatment of wounded with gunshot fractures of long bones.

The acute cholangitis was observed in 35 patients, which was caused of the biliary sepsis in 10 cases. The patients were divided into three groups: group I (n = 95), where endoscopic methods of biliary decompression were used; group II (n = 48), where biliodigestive anastomoses were formed; and group III (n = 57), where the external drainage of bile ducts was conducted.

Results. The patients of the group I demonstrated a gradual decrease of bilirubin and alkaline phosphataselevels, whichreachedthenormalreadings on Day 7. The patients of the group II demonstrated normal levels of bilirubin and alkaline phosphatase on Day 14. The patients of the group III demonstrated rapid decrease of bilirubin and alkaline phosphatase levels, which reached the normal readings on Day 28. The transaminase level in each group of patients had reached the norm earlier.

Conclusions. Priority is given to stage surgical tactics in patients with obstructive jaundice complicated of the acute cholangitis and biliary sepsis. Single-stage correction is recommended for patients with hyperbilirubinemia of less than 200 mcmol/l and duration of jaundice for less than 14 days, in the presence of compensated or subcompensated co-occurring pathology as well as in the absence of acute cholangitis.

Lo que los juristas no dicen. Normas no expresadas y despositivización
Authors: Barberis Mauro
Published: June 2019

Uno de los problemas más intrigantes de la reciente teoría del derecho está representado por las reglas implícitas y/o no expresadas. Sin embargo, el tema, propuesto por Riccardo Guastini en los años noventa del siglo pasado, incomoda a otros juristas y teóricos: de hecho, lo discuten casi solo los genoveses y sus amigos, como veremos. El artículo reconstruye la tematización del problema, estrechamente relacionado con otros típicos temas «genoveses», como son la distinción interpretación/construcción y el mismo concepto de marco de Kelsen. Aquí se distinguen, especialmente, las normas implícitas de las normas (totalmente) no expresadas, volviendo a definir las primeras como una variable dependientede su aplicación judicial, y considerando las segundas como un elemento del proceso que llamo despositivización del derecho.

La Fenología es la ciencia que estudia los eventos periódicos naturales que ocurren en los seres vivos incluyendo sus relaciones con los fenómenos meteorológicos. Registra la actividad biológica visible de los organismos y la relaciona con el sistema climático del lugar. En el presente trabajo se determinó la fenología y los requerimientos biometeorológicos de Erytrhina crista-galli (Ceibo) y Handroanthus heptaphyllus (Lapacho rosado) en el sur de la provincia de Santa Fe (Argentina). El estudio se realizó durante los años 2014, 2015 y 2016, en el Parque Villarino de la Facultad de Ciencias Agrarias de la UNR. Las observaciones se llevaron a cabo en cinco ejemplares de E. crista-galli y en tres de H. heptaphyllus. Las etapas fenológicas observadas fueron: brotación, floración, fructificación y caída del follaje. E. crista-galli presentó una floración bimodal, siendo el primer episodio el más intenso, con una duración media de 31 días. El segundo evento mostró menor intensidad y fue más prolongado, durando 57 días en promedio. En H. heptaphyllus la etapa de floración se registró antes de que emerjan las hojas, con una duración promedio de 33 días. Para las dos especies, esta fase fenológica fue la más acotada. La temperatura base calculada para E. crista-galli fue de 10°C y para H. heptaphyllus de 11°C, para todo el ciclo.

According to the results of systematic reviews of WHO, maternal mortal-ity associated
with massive bleeding almost reached 30% and has no tendency to decrease. Among the causes of massive obstetric hemorrhage, the most challenging ones are uterine hypotension and morbidity adherence placenta. Most severe complication for placentation is placenta increta in the uterine wall. Over the past 50 years, the number of cases with morbidity adherence placenta has in-creased tenfold. By all indications, this pathology has taken on the character of an epidemic and is one of the main causes for massive blood loss and blood transfusion, as well as peripartum hysterectomy. For surgical hemostasis in this pathology we apply X-ray vascular methods (temporary balloon occlusion of large vessels, vascular embolization), ligation of the iliac, uterine, ovarian arteries, various versions of distal hemostasis, including the use of uterine turnstiles, intrauterine and vaginal cylinders, compression sutures. However, data confirm-ing the advantage of any specified methods are not enough. The risk of massive bleeding is high while using any of these methods. The article analyzes the blood saving methods existing at the present stage and possibility of these methods usage in obstetrics. Besides, we describe efficacy and safety of their use in massive blood loss, including the surgical treatment of morbidity adherence placenta.
