Published: February 2020

In Europe, cowpox virus (CPXV) infection in South American camelids occurs as a so-called spill-over infection. Although infected animals generally have a mild form of the disease and survive, cases of fatal generalised CPXV infection have also been described. Prevention by prophylactic vaccination is the only way to protect animals from disease. In the present study, modified vaccinia virus Ankara (MVA) vaccine, which has been successfully used in many animal species, was used in a prime-boost vaccination regimen in two alpaca herds with a history of CPXV infection. The focus of the study was the prevention of further clinical cases, and to determine the safety and immunogenicity of the MVA vaccine in alpacas. The MVA vaccine was well tolerated and safe in the 94 animals vaccinated. An indirect immunofluorescence assay (IFA) using MVA as an antigen showed that the seroprevalence of antibody after booster vaccination was 81.3% in herd I and 91.7% in herd II. Detectable antibody titres declined to 15.6% in herd I and 45.8% in herd II over a 12-month period after booster vaccination. Animals could be divided into four groups based on individual antibody titres determined over one year: Group 1 consisted of 19.3% of animals that were seropositive until the end of the trial period; Group 2 consisted of 58.0% of animals that were seropositive after booster vaccination, but seronegative one year later; Group 3 consisted of 14.7% of animals that were not seropositive at any time point; and Group 4 consisted of 7.9% of animals that were seropositive after initial immunisation, seronegative six months later, but seropositive or intermediate in IFA one year after immunisation, likely because of natural exposure. In new-born crias born to MVA-vaccinated mares, specific maternal antibodies were detected in 50.0% of animals up to 14 weeks of age. Our results confirm that MVA vaccination is a feasible tool for the prevention of CPXV disease in alpacas. Long-term studies are needed to verify future vaccination regimen in CPXV affected herds.

Cowpox virus (CPXV) belongs to the genus Orthopoxvirus in the Poxviridae family and is endemic in western Eurasia. Based on seroprevalence studies in different voles from continental Europe and UK, voles are suspected to be the major reservoir host. Recently, a CPXV was isolated from a bank vole (Myodes glareolus) in Germany that showed a high genetic similarity to another isolate originating from a Cotton-top tamarin (Saguinus oedipus). Here we characterize this first bank vole-derived CPXV isolate in comparison to the related tamarin-derived isolate. Both isolates grouped genetically within the provisionally called CPXV-like 3 clade. Previous phylogenetic analysis indicated that CPXV is polyphyletic and CPXV-like 3 clade represents probably a different species if categorized by the rules used for other orthopoxviruses. Experimental infection studies with bank voles, common voles (Microtus arvalis) and Wistar rats showed very clear differences. The bank vole isolate was avirulent in both common voles and Wistar rats with seroconversion seen only in the rats. In contrast, inoculated bank voles exhibited viral shedding and seroconversion for both tested CPXV isolates. In addition, bank voles infected with the tamarin-derived isolate experienced a marked weight loss. Our findings allow for the conclusion that CPXV isolates might differ in their replication capacity in different vole species and rats depending on their original host. Moreover, the results indicate host-specific differences concerning CPXV-specific virulence. Further experiments are needed to identify individual virulence and host factors involved in the susceptibility and outcome of CPXV-infections in the different reservoir hosts.

Published: February 2020

Porcine epidemic diarrhea virus (PEDV), being highly virulent and contagious in piglets, has caused significant damage to the pork industries of many countries worldwide. There are no commercial drugs targeting coronaviruses (CoVs), and few studies on anti-PEDV inhibitors. The coronavirus 3C-like protease (3CLpro) has a conserved structure and catalytic mechanism and plays a key role during viral polyprotein processing, thus serving as an appealing antiviral drug target. Here, we report the anti-PEDV effect of the broad-spectrum inhibitor GC376 (targeting 3Cpro or 3CLpro of viruses in the picornavirus-like supercluster). GC376 was highly effective against the PEDV 3CLpro and exerted similar inhibitory effects on two PEDV strains. Furthermore, the structure of the PEDV 3CLpro in complex with GC376 was determined at 1.65 Å. We elucidated structural details and analyzed the differences between GC376 binding with the PEDV 3CLpro and GC376 binding with the transmissible gastroenteritis virus (TGEV) 3CLpro. Finally, we explored the substrate specificity of PEDV 3CLpro at the P2 site and analyzed the effects of Leu group modification in GC376 on inhibiting PEDV infection. This study helps us to understand better the PEDV 3CLpro substrate specificity, providing information on the optimization of GC376 for development as an antiviral therapeutic against coronaviruses.
Effect of Incident Acoustic Pressure Amplitude on the Transmission Loss of Helmholtz Resonators
Authors: Sachedina Karim , Lato Thomas , Mohany Atef , Hassan Marwan
Published: February 2020

Acoustic transmission loss is a common parameter utilized throughout several studies to evaluate the acoustic characteristics of a given test element. Transmission loss has been frequently referred to as a source independent parameter. However, this work presents evidence that the incident acoustic pressure amplitude does, in fact, have an effect on the measured transmission loss for some passive damping devices. The transmission loss was experimentally measured utilizing the two-source location method and the specimens tested include an expansion chamber, a quarter wave resonator, a Herschel–Quincke tube and various Helmholtz resonators. When varying the power supplied to the acoustic source, it was noted that all the devices exhibited nearly constant values of transmission loss, with the exception of the Helmholtz resonators. The Helmholtz resonators had a significant variance of transmission loss with respect to the acoustic source power. This decrease in performance is caused by the “jet-flow” phenomenon occurring at the Helmholtz resonator neck, which results in increased acoustic losses. The present work illustrates that the assumption of source independence, which is often made when using transmission loss to evaluate damping devices, must be taken with caution, as this assumption is case dependent and may be crucial when scaling experimental studies to an industrial setting.

Abstract - Fire search and obstacle avoidance robot are types of mobile robots that can find targets in the form of fire by tracing walls. For this robot, the navigation system uses navigation using walls. Navigation using walls is an algorithm to guide robots by navigating along walls. This system works by adjusting the distance from the wall to the robot. If a change occurs, the robot moves to adjust the distance again. This robot consists of several main components to support it when navigating through walls to reach the target. This robot consists of a flame sensor placed on the front that serves as a detector for targets in the form of fire. In addition to the flame sensor, three ultrasonic sensors are located on the left, front and right of the robot. These three ultrasonic sensors function as wall detectors. Based on the test, the percentage of success of the robot reaches the target of fire by tracing the wall of the right side is 100% in room II, in room III 70%, in room IV 70% Whereas by tracing the left wall, the percentage of success in room II is 60%, in room III 70%, in room IV 100%. The success percentage of robots reaching the target with the right search method is 80% and the left is 76.667%.

Automatic Coffee Mixer Simulator with Tunning PID Methode on LabVIEW
Authors: Rustandi Ade
Published: February 2020

Abstract - Coffee is a drink that many people consume as an encouraging and casual meal. Coffee consumption can eliminate boredom due to daily activities. Therefore, coffee is very beneficial for people who enjoy coffee. But in serving doses of making coffee drinks in stalls or cafes still use manual methods, so the dose of coffee is not right. Every time you make a large amount of coffee drinks there may be several coffee drinks with different flavors. Therefore an automatic coffee maker is made so that the resulting coffee drink has the same taste. The system design for automatic coffee drink makers uses the LabVIEW application program, with the PID controller method to get the coffee content that you want to serve. The parameters of the content to be regulated are coffee, milk and sugar by setting the value of Kp = 398.52; Ki= 3.06; and Kd= 0.765. By setting a point, the value of the mixed content will remain stable as desired. Keyword : PID, Tunning PID, Coffe Mixer Simulation, LabVIEW, PID simulation, Coffe Mixer PID
In Situ Exfoliation and Pt Deposition of Antimonene for Formic Acid Oxidation via a Predominant Dehydrogenation Pathway

Published: February 2020

Direct formic acid fuel cell (DFAFC) has been considered as a promising energy conversion device for stationary and mobile applications. Advanced platinum (Pt) electrocatalysts for formic acid oxidation reaction (FAOR) are critical for DFAFC. However, the oxidation of formic acid on Pt catalysts often occurs via a dual pathway mechanism, which hinders the catalytic activity owing to the CO poisoning. Herein, we directly exfoliate bulk antimony to 2D antimonene (Sb) and
in situ
load Pt nanoparticles onto antimonene sheets with the assistance of ethylenediamine. According to the Bader charge analysis, the charge transfer from antimonene to Pt occurs, confirming the electronic interaction between Pt and Sb. Interestingly, antimonene, as a cocatalyst, alters the oxidation pathway for FAOR over Pt catalyst and makes FAOR follow the more efficient dehydrogenation pathway. The density functional theory (DFT) calculation demonstrates that antimonene can activate Pt to be a lower oxidative state and facilitate the oxidation of HCOOH into CO
2
via a direct pathway, resulting in a weakened intermediate binding strength and better CO tolerance for FAOR. The specific activity of FAOR on Pt/Sb is 4.5 times, and the mass activity is 2.6 times higher than the conventional Pt/C.

Tulisan ini membahas tentang pembaharuan hukum perkawinan tentang batas minimal usia pernikahan dan akibat hukumnya. Masalahny adalah faktor apa saja yang menyebabkan pernikahan di bawah umur dan dampak apa saja dari pernikahan di bawah umur tersebut. Permasalahan ini akan dikaji dengan menggunakan metode penelitian dengan pendekatan kualitatif. Penelitian ini ditemukan bahwa tidak ada pengaturan hukum yang khusus menyangkut perkawinan anak dibawah umur. Anak dibawah umur menurut sistem hukum di Indonesia yaitu Undang-Undang Perkawinan (UUP) di Indonesia adalah anak yang berusia 19 (sembilan belas) tahun untuk pria dan wanita. Walaupun telah ditegaskan mengenai batas usia minimum diperbolehkan menikah oleh Undang-Undang, namun disisi lain diberikan pengecualian untuk itu. Pengecualian itu disebut dengan pemberian dispensasi kawin untuk anak dibawah umur. Anak dibawah umur yang mendapat dispensasi kawin boleh melaksanakan perkawinan walaupun masih dibawah umur. Anak dibawah umur yang mendapat dispensasi kawin setelah melaksanakan perkawinan, dianggap dewasa dan dianggap cakap dalam melakukan suatu perbuatan hukum, atau ia nya tidak berada dibawah pengampuan orangtuanya lagi
Measurement-Based 5G Millimeter-Wave Propagation Characterization in Vegetated Suburban Macrocell Environments
Authors: Zhang Peize , Yang Bensheng , Yi Cheng , Wang Haiming , You Xiaohu
Published: February 2020

An empirically based analysis of propagation characteristics in two vegetated suburban areas with different types and fractions of vegetation cover in 5G millimeter-wave bands is presented. A basic distance-dependent path loss model with a Gaussian random variance for shadow fading is utilized in accordance with the maximum-power directional and omnidirectional measurement data, therein exploiting significant path loss exponents in the presence of vegetation. In comparison with the existing ITU-R and 3GPP models, the effect of dense-leaved trees on path loss prediction is similar to that of buildings, whereas these standard models are inapplicable for sparse obstacle-line-of-sight (OLoS) links. Consequently, an azimuth-angle-based path loss characterization is proposed considering the antenna pattern, beam misalignment, and blockage effects. Moreover, several composite and cluster-level small-scale channel parameters, such as the number of clusters, delay spread, and angular spread, are extracted. Analysis of the first-arrival cluster in the OLoS setting reveals that forward scattering through foliage is still dominant and is expected to produce a larger azimuth angular spread of the arrival and compact multipath components in the time domain compared with line-of-sight and reflected clusters. Measurement results improve existing 3GPP channel models for suburban macrocell scenarios in millimeter-wave bands.

Published: February 2020

As the fifth-generation (5G) mobile communication

is utilizing millimeter-wave (mmWave) frequency bands, electromagnetic field (EMF) exposure emitted from a 5G mmWave mobile handset should be evaluated and compliant with the relevant EMF exposure limits in terms of peak spatial-average incident power density. In this work, a fast power density (PD) assessment method for a 5G mmWave mobile handset using the equivalent currents (EQC) method is proposed. The EQC method utilizes the intermediate-field (IF) data collected by a spherical measurement system to reconstruct the EQCs over a reconstruction surface, and then computes the PD in

close proximity of the mobile handset with acceptable accuracy. The performance of the proposed method is evaluated using a mmWave mobile handset mock-up equipped with four quasi-Yagi antennas. The assessed PD results are compared with those computed using full-wave simulations and also those measured with a planar near-field (NF) scanning system. In addition, three influencing factors related to the accuracy of the EQC method, namely, the angular resolution, the phase error, and the handset

position in the IF measurements, are also analyzed. The proposed method is a good candidate for fast PD assessment of EMF exposure compliance testing in the mmWave frequency range.

La Etnobotánica y el paisaje del maguey como recurso natural para el desarrollo del poblado de San Gabriel Azteca de Zempoala Hidalgo, México
Authors: Ríos Martínez Alicia , López de Juambelz Rocío
Published: February 2020

San Gabriel Azteca es un pequeño poblado localizado en el estado de Hidalgo que en décadas anteriores perteneció a una prolífica zona pulquera sobre la cual basó su economía. El maguey es una planta que crece naturalmente en el sitio y de la cual se obtienen múltiples productos entre ellos el pulque, por lo que el paisaje rural estuvo dominado por este cultivo. Actualmente la región presenta una evolución de este paisaje, lo que ocasiona una progresiva pérdida de esta «cultura del maguey» que daba identidad al poblado a través de diferentes usos como: los comestibles, los domésticos, la medicina tradicional, la construcción y el uso agrícola. La etnobotánica del maguey permite dar otras alternativas de desarrollo económico y con ello revalorar esta planta tan ligada a la cultura mexicana de la cual se obtienen múltiples beneficios, entre ellos la recuperación ecológica de la región que comienza a degradarse.

Di dalam quran menjelaskan kualitas serta nilai manusia dengan menggunakan empat jenis istilah yang satu sama lain saling berkaitan yaitu al-insaan, an-naas, al-basyar, dan bani adam. Manusia yang dijuluki sebagai al-insaan karena dia sering menjadi pelupa sehingga diperlukan teguran dan peringatan. Kemudian an-naas (terambil dari kata annaws
yang berarti gerak, dan ada juga yang berpendapat bahwa ia berasal dari kata unaas yang berarti nampak) digunakan untuk menunjukkan sekelompok manusia baik dalam arti jenis manusia atau sekelompok tertentu dari manusia. Selanjutnya disebut al-basyar, karena dia cenderung perasa dan emosional sehingga perlu disabarkan dan didamaikan. Manusia disebut sebagai banii Aadam karena dia menunjukkan pada asalusul
yang bermula dari nabi Adam as sehingga dia bisa tahu dan sadar akan jati dirinya. Misalnya, dari mana dia berasal, untuk apa dia hidup, dan ke mana ia akan kembali. Penggunaan istilah banii Aadam menunjukkan bahwa manusia bukanlah merupakan hasil evolusi dari makhluk anthropus (sejenis kera). Hal ini diperkuat lagi dengan panggilan kepada Adam dalam quran oleh Allah dengan huruf nidaa (Yaa Adam)

Abstract
Bediuzzaman Said Nursi’s thoughts and activities on da’wah had been an unique model of the responses to western modernization in Turkey after the declining Ottoman Empire in nineteenth and early-twentieth centuries. Nursi intended to provide an Islamic answer based on Qoranic values to the attacks of westernization and secularization by several strategies of da‘wah with using cultural and political approach. He also had used special methods which can be summarized with three phrases: mânevi jihad (jihad of the word), publicated writings, and positive action. His thoughts and activities on da‘wah had impacted strongly on rising The Nur Community (Nurculuk) as the most significant religious and social movement with millions of adherents and a strong institusional system throughout the country. The Nur Community had published largely Nursi‘s thoughts round of the world and paid attention to realize his Risale-i Nur’s doctrines in serving of all human being in their daily life in the modern era.

Published: February 2020

The objective of the study is the low-pressure membrane process for treating aqueous solutions containing food dyes and surfactants. The influence of surfactants (SDS � sodium dedecil sulphate, SO � sodium octanoate) in the separation of synthetic food dyes (E104 � quinoline yellow) was analyzed. Polysulfone and polysulfone-polyaniline membranes were used. Dye and surfactant concentrations used were 10% (equivalent to 100g/m3). The pressures used in the ultrafiltration process were 0.1, 0.2 and 0.3 MPa. When dye containing solutions were passed through the membranes, an increase in their flux was observed. The presence of surfactants in the solutions lead to a decline in flux when pressures of 0.1 and 0.2 MPa were used, but an improvement could be seen as the pressure increased to 0.3 MPa, for both dead-end and cross-flow filtration. Using only dead-end alternative, higher fluxes were achieved for both membranes, but it decreases with time due to accumulation on the membrane surface. The use of cross-flow filtration did not allow accumulation on the membrane surface so that the flux was constant in time.The use of anionic surfactants improved the food dye retention. The interactions between membranes and surfactants can be an important factor supporting the efficiency of the ultrafiltration.

The controlled the solvo-hydro-thermal titanium dioxide synthesis moderated by dimedone from organometallic precursors is approached in order to obtain nanoparticles compatible with the polymeric systems used in the dental technique. The experiments carried out with relation to the production of titanium dioxide nanoparticles using the solvo-hydro-thermal synthesis allowed the production of three types of materials by means of varying the nature of the used solvent: methanol, ethanol and propanol (TiO2-M, TiO2-E and TiO2-P).The characterisation using electron microscopy (SEM and HRTEM), X-ray analysis, FTIR and UV-Vis spectrometry show that the diameter of the produced nanoparticles is less than 15 nm and decreases in the order: dpMethanol ] dpEthanol ] dpPropanol. The nanoparticles contain trace organic substances which the smaller they are, the bigger the alcohol chain used as a solvent is. The adsorption of a target dye showed increasing values with the increasing number of atoms in the hydrocarbon alcohol chain. The highlighted characteristics suggest the possibility of using the synthesised nanoparticles in the production of hard implants for dental reconstruction.
Complex Systems of Distillation Columns Used in the Production of the Propylene Oxide
Authors: Nicolae Marilena
Published: February 2020

Complex systems of distillation columns were intensively studied within last decades and continue to show interest for researchers and for industrial application. The first designed complex distillation column with heat integration was the Petlyuk column and the development of complex systems of columns continued up to dividing wall columns (DWC) which are increasingly being used in industry. DWC are usually used to separate three products, components or fractions, from a multicomponent mixture. This study attempts to find the best fitting of complex systems of columns in the process of propylene oxide (PO) obtaining using the method of propylene chlorination and presents a proposed variant of separation which can lead to a reduced energy consumption. The fabrication of PO through this method lead to a multicomponent mixture which is separated in two main products: propylene oxide (PO) and heavier components containing as valuable compound 1,2 dichloropropane (DCP). Both products, PO and DCP, have important uses in the chemical industry. The study of complex schemes of columns used for PO separation was assessed by simulation using a simplified method based on Fenske � Underwood - Gilliland correlation (F.U.G.) [1]. The systems studied in this work include the following configurations of columns: column with prefractionator, column with partially coupled prefractionator, the Petlyuk column, the dividing wall column, column with side striper, column with side rectifier, the direct and the indirect sequence.

Pyrazol derivative containing 2-fluorophenyl group 2a was converted into carboxylic chloride derivative 3a by thionyl chloride and then the compound 4a was obtained from reaction ammonia with compound 3a. In the next step, 4-benzoyl-1-(2-fluorophenyl)-5-phenyl-1H-pyrazole-3-carboxylic acid 2a was reacted with MeOH/H2SO4, EtOH/H2SO4, 2-nitrophenylhydrazine and 3-nitrophenylydrazine to give 5a,b and 6a,b pyrazol derivatives, respectively. The structures regarding all compounds synthesized were determined by the IR, NMR and elemental analysis method.

Recipient type products from energetic and chemical industry undergo a wide combined process of corrosion and ware, due to working environment. In order to put this products back in use, in a shorter period of time, welding reconditioning procedures are applied which mainly aim to restore the geometrical configuration but also the characteristics growth. Any welding technology applied, involves melting a filler material but also a part of the base material, mixing them, thereby obtaining the welded joint. The paper present the experimental results obtained in determining the optimal parameters for Metal Active Gas welding deposit that are going to be used for the restoration of some components from energetic and chemical industry and that are highlighting the dependence between the deposit parameters and the chemical composition of the juncture.

Manufacturing of Portland cement consists of high volume of natural aggregates which depleted rapidly in today construction field. New substitutable material such as bottom ash replace and target for comparable properties with hydraulic or pozzolanic properties as Portland cement. This study investigates the replacement of different sizes of bottom ash into Portland cement by reducing the content of Portland cement and examined the mechanism between bottom ash (BA) and Portland cement. A cement composite developed by 10% replacement with 1, 7, 14, and 28 days of curing and exhibited excellent mechanical strength on day 28 (34.23 MPa) with 63 mm BA. The porous structure of BA results in lower density as the fineness particles size contains high specific surface area and consume high quantity of water. The morphology, mineralogical, and ternary phase analysis showed that pozzolanic reaction of bottom ash does not alter but complements and integrates the cement hydration process which facilitate effectively the potential of bottom ash to act as construction material.

The relations for calculus of: 10M HNO3 solution flow, isotopic transport, 15N molar fraction at the bottom of the separation column, product flow, interphasic transfer velocity, height equivalent to the theoretical plate and sulfur dioxide flows in both stages of the product refluxer are presented for 15N separation column with different diameters and 10M HNO3 feeding flow rates, operated at pressure up to 1.5 atm. In order to produce the isotope 15N at 99 at. % 15N by isotopic exchange in Nitrox system it is desirable to operate the production plant at biggest flow of 10M HNO3 solution, which allows the 15N production at that concentration on a given plant. That will be possible by operating the plant at pressure as it is shown in this work. At 0.8 atm pressure (1.8 atm absolute) the isotopic separation at higher flow rates would be practically equal with that obtained at lower flow rates and atmospheric pressure. For constant: HETP = 10.85 cm, 15N molar fraction of the feeding 10M HNO3, Nf = 0.00365, and of the product, Np = 0.12, the variation of the primary separation column product and of the 15N production plant, as a function of the feeding flow with 10M HNO3 solution, are also presented.

Technological developments have led to the implementation of novel digitalized manufacturing methods for the production of metallic structures in prosthetic dentistry, less studied to date. The objective of the study was to assess the morphological characteristics and corrosion properties of selective laser sintered (SLS) and selective laser melted (SLM) cobalt�chromium (Co�Cr) dental alloys related to the surface processing and pH variations. For the experimental analyses metallic specimens made of Co-Cr dental alloys were prepared using SLS and SLM, as indicated by the manufacturers. The morphology and the topography of the samples were investigated by scanning electron microscopy and atomic force microscopy. Electrochemical measurements were made and the values for corrosion potential (Ecorr), corrosion current (icorr) and corrosion rate were calculated. The immanent advantages of additive technologies are accompanied by porosities resulted after the deposition of the fine metallic powder, especially for the SLM method. Considering the corrosion current density value a parameter which provides information on the kinetics of the corrosion process, SLS samples showed better performance under pH variations. Surface processing can result in an improvement in the corrosion performance also for extreme pH values. Given that the microstructure and corrosion behavior was significantly different, further differences in the clinical behavior of prosthetic restorations manufactured using SLS and SLM additive techniques are anticipated.

Complex ceramic superficial ceramic layers (Al2O3, SiO2, YO, ZrO2) were obtained by atmospheric plasma deposition, industrial wide application method, on a metal support Fe-C (FC 250). The substrate was sandblasted mechanically prior to depositing 6 successive layers of ceramic material. The obtained layers were analyzed structurally (scanning electron microscopy, SEM), chemical (spectroscopy of X-ray, EDAX) and mechanically (scratch tests) to characterize the new compound material obtained (thin layer-substrate). It was observed from the experimental results that there was a relationship between the state of the surface of the substrate and the adhesion of the ceramic layers to the metal surface.

Anaerobic digestion is a complex process that allows the conversion of organic wastes into biogas with minimal costs and benefits for the environment. The goal of this study is to evaluate the anaerobic digestion potential of two common agricultural biomass wastes (degraded corn and degraded wheat) used as single substrates or as co-substrates together with wastewater from a waste water treatment plant. The results reveal that the co-digestion is an improved solution, both in terms of biogas amount produced and its methane concentration. Two kinetic models (modified Gompertz model and logistical growth model) were applied to study the methane production. For each case, the kinetic parameters were estimated. One demonstrates that the modified Gompertz model fitted very well the measured methane potential, for all studied cases.

The progress of fundamental medical sciences, of other medical and surgical specialties enabled a fast development pace of modern maxilla-facial surgery. Oro-maxilla-facial surgery bring together science and art in order to prevent, diagnose and cure disease, to reconstitute shapes and restore functions of the oro-maxilla-facial area often by surgery. Apical surgery is a standard surgical procedure including incision of the apex and resection of the apical and periapical diseased site, preceded or not by the correct endodontic treatment and the adequate root canal obturation. Periapical pathology is maintained in an endodontic treatment considered correct, being resolved by endodontic surgery with apicoectomy and avoiding extracting the causal tooth. In this way the area is kept as favorable as possible for future prosthetic works. It is achieved mostly in monoradicular teeth and this intervention is suitable for molars, yet the topography and the morphology of the molars make the surgery more difficult. Oral surgery and endodontics have accumulated a rich experience in maintaining the teeth on the arch for as long as possible. The study material for endodontic case selection, examination and resolving is gathered from the Clinic of Oral and Maxillo-Facial Surgery of the Spiridon Teaching Hospital over a period of two years, from 2014 to 2016; the study group for endodontic therapy and surgery comprises 59 patients. To receive apicoectomy, the tooth and its periodontium should meet certain conditions after apicoectomy, the operated root needs to keep an osseous implantation length equal to two thirds or at least half its initial length. Complex oral rehabilitation of various clinical cases met in dental surgery is a challenge for the dental surgeon due to the various degrees of impairment of all system elements. The emerging malfunction is difficult to diagnose and to treat, asking for dental surgeon�s special experience and clinician skills.

The general warming of climate disturbed the evolution of natural factors: water and soil, climate changes in the vineyard ecosystems and the summers became hotter and drier, the autumns are longer, the winters are shorter and seldom excessive, droughts are common and wet periods are excessively rainy. Soil contains plant nutrients, minerals, organic matter and seeds. It can also contain pesticides and toxic heavy metals. Building disturbs and loosens soil and can create large volumes of dust and debris. We consider that the results of these researches will have a special utility for both private farmers and companies, because in this area of NE region of Romania the viticulture has tradition and brings important income to growers. The goal of this paperwork was to analyses the influence of some factors such as variety of grapes and applied agro techniques on the growth and development of the grapevine and especially the impact of the applied technology on the productive potential of the surface unit, in order to improve some maintenance technologies of this species and the choosing of the best varieties which respond the best to the climate changes. The suitability of the grapevine culture results from the interference of the main ecological requirements of the species: light (light energy), temperature (solar energy), water (soil and air humidity), soil (root culture medium), nutrients and the air (the composition) for growth and development and the natural setting, which the area can offer to the studied species. The crop yield depends primarily on variety, on the interaction with the pedo - climatic factors and the applied technology. The necessity of the chosen topic is justified by the importance of the technological factors on the grapevine culture.
