Published: June 2018

The paste thickener could increase the water recovery and reduce the environmental impacts in tailings dam. The present work aimed to find the appropriate scale-up factor for bed depth to design paste thickener for copper tailings, using a lab glass cylinder and an operating pilot column. The thickening tests were carried out on the flotation tailing samples obtained from the Sarcheshmeh and Miduk copper mines located in Iran. Based on the industrial conditions, the values of influential parameters for paste thickener used in these experiments were pH=11 and feed solid=10 %. Flocculant type was NF43U and used as 25g/t with dosage of 0.25 gt. The unit area of Sarcheshmeh and Miduk paste thickeners were designed as 0.057 and 0.047m2/t/day, respectively. Based on the dry feed rates to each paste thickener as 7920 and 4320 t/day, the thickener's diameters were determined as 23.9 and 16.1 meters which are similar to the actual thickener’s diameters (24 and 16 meters), respectively. In addition to unit area, the bed depth is also important in the paste thickeners design. Hence, the ratio of industrial to lab unit bed volume for Sarcheshmeh paste thickener was obtained 75 which was equal to the ratio of industrial to lab bed depth (bed depth scale-up factor exclusively for copper flotation tailings). This procedure was validated by using the Miduk sample. The bed depth in the paste thickeners was determined as 7.5 meters, by using the bed depth scale-up factor which was comparable to the actual bed depth (8 meters). This research confirmed that the bed depth scale-up factor is able to correctly determine the bed depth of industrial paste thickeners for copper tailings.

Published: June 2018

<p>Using daily data of oil prices and exchange rates of 14 countries for the period January 1999 to November 2014, this study examines the dynamic correlation between oil prices and exchange rates by DCC-GARCH model. The results show the significant negative correlation between oil prices and exchange rates over the period. These results imply that the increase of oil price is coinciding with US dollar depreciation and vice versa. This correlation strengthens in negative direction during financial crisis period, while it shifts to an upward trend after financial crisis period.</p>
Continuous- discrete mathematical model for control of growth of a plant population in a given time period under a given budget
Authors: Bhattacharya Dilip Kumar 
Published: June 2018

The paper discusses an economically viable way of controlling biomass of a vegetable plant population under the use of fertilizer in a given span of time under a given budget of expenditure. The span of time is divided in some suitable consecutive periods of equal duration P, called cohorts. The treatment is done on the available population of plant at the beginning of each cohort for a suitable time; the continuous dynamics in the change of biomass for this time period is governed by an ordinary differential equation involving total effort exerted in treating the initial population. Taking this improved value at the end of the time period as the initial value, the biomass of the population is allowed to move under its normal continuous dynamics given by Logistic growth equation for the rest of the time of that cohort. The final concentration of the biomass at the end of the first cohort is obtained by following the above two types of dynamics. This is also considered as the starting biomass for the next cohort. The same process adopted for the first cohort is repeated for calculating the improvement of the biomass in the second cohort and the whole process is repeated till the end of the final cohort is reached. Next an objective function is formed for the given span of time. This measures the net profit in getting improvement in the weight of the biomass less the cost involved in the process of improving the weight of the biomass for the given period of time. As the analysis is done in considering different cohorts at regular intervals of time, so it is a discrete model. As within each cohort, the dynamics takes place continuously, so it is a continuous model too. As a whole, the model is found to be a continuous- discrete model. Hence method of optimal control for continuous-discrete model is used to determine how the treatment at the starting of each cohort be adjusted, depending on the allocated budget, so that the total net profit is maximum.

<p><span lang="EN-US">Fire is one of the most serious hazards for forests on earth. Despite each kind of technological development and equipment, fire activity has an increasing trend because of especially climate change and socio-economic reasons. Although fire extinguishing organizations, today, try to suppress this increasing risk with a maximum effort, the big fires in some places cause the enormous areas to get burned. The fires as big as natural disasters cannot be extinguished most of the time in spite of any efforts or methods when the extreme fire weather conditions come together with inflammable matters and ignition sources. </span></p><p><span lang="EN-US">In this study, the number and area of forest fires in Turkey were investigated through statistical quality control method. Despite the decreasing trend of forest fires in terms of area size, the possibility of large fires always exists in the whole Mediterranean Region due to the socio-economic conditions such as increasing human population, migration and any changes that could affect fire activity in climate conditions. As a result of the study, it is seen that there is an overall increase in the number of fires while the burned area decreases. Out-of-control behaviors in control graphs are not in a continuous trend but sometimes exceed the control limits. This condition is seen to be positive as a trend but also points to the possibility of unexpected annual burned area and the number of fires.</span><strong></strong></p>

Published: June 2018

Background:
This article proposes the design and implementation of a MMIC (monolithic
microwave integrated circuits) Power amplifier using the ED02AH process.

Methods:
The MMIC ED02AH technology have been developed specifically for microwave applications
up to millimeter waves, and for high-speed digital circuits. The use of a single branch of a power
amplifier can produce high distortion. In the present paper, the Linear amplification with nonlinear
components (LINC) method is introduced and applied as a solution to linearize the power amplifier, it can
simultaneously provide high efficiency and high linearity. To validate the proposed approach, the design
and characterization of a 5.25 GHz LINC Power Amplifier on MMIC technology is presented.

Results:
Good results have been achieved, and an improvement of about 37.50 dBc and 59 dBc
respectively is obtained for the Δlower C/I and Δupper C/I at 5.25 GHz.

Conclusion:
As a result of this method, we can reduce the Carrier Power to Third-Order Intermodulation
Distortion Power Ratio. Excellent linearization is obtained almost 37.6 dBc for Δlower C/I and 58.8 dBc
for Δupper C/I.

DATABASE SYSTEM SUGGESTIONS FOR THE INTERNET OF THINGS (IOT) SYSTEMS
Authors: KALAY Mustafa Utku 
Published: June 2018

Internet of
Things (IoT) is an interconnection of different types of information assets in
which data is continuously generated and transmitted over the Internet.
Technologies of the sensor, RFID, GPS, mobile devices, and Internet-enabled
actuators play a significant role in IoT systems. IoT brings out new challenges
in terms of data and information management because it is not easy to collect
and manage a large amount of heterogeneous data that is aggregated at very high
velocity as well as to retrieve and manage the information that is hidden
within this large volume of data. In this
paper, I discuss the main factors affecting the efficiency of data management
in IoT systems, specifically query processing and transaction management. There
are many lessons learned from traditional database systems, distributed
systems, and sensor networks, however, traditional solutions are often
inadequate to meet the needs of applications in such a complex ecosystem,
namely IoT. In traditional database systems, for instance, query operations are
usually local, and execution costs depend on the current processor power and
other resource constraints (i.e. memory). On the other hand, transaction
management mechanisms guarantee the ACID properties in order to provide overall
data integrity. It is apparent that different types of IOT applications that
operate on heterogeneous, streaming, real-time, and geographically distributed
large data will significantly change the well-known aspects of querying and
transaction management. Context-aware querying, distributed querying, MapReduce
computing model and flexible transaction models such as web-based transaction
handling are some of the current issues discussed in this paper. With the succinct yet comprehensive information
presented in this work, I intend to provide a guide for researchers in the IoT
systems, especially in the context of database systems.

Authors: SoutoMaior JR , de Moraes SLD , Lemos CAA , Vasconcelos BC do E , Montes MAJR , Pellizzer EP 
Published: June 2018

SUMMARY

Objective:
A systematic review and meta-analyses were performed to evaluate the efficacy of tooth color change and sensitivity of teeth following in-office bleaching with and without light gel activation in adult patients.

Methods:
This review was registered at PROSPERO (CRD 42017060574) and is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Electronic systematic searches of PubMed/MEDLINE, Web of Science, and the Cochrane Library were conducted for published articles. Only randomized clinical trials among adults that compared in-office bleaching with and without light activation with the same bleaching gel concentrations were selected. The outcomes were tooth color change and tooth sensitivity prevalence and intensity.

Results:
Twenty-three articles from 1054 data sources met the eligibility criteria. After title and abstract screening, 39 studies remained. Sixteen studies were further excluded. Twenty-three studies remained for qualitative analyses and 20 for meta-analyses of primary and secondary outcomes. No significant differences in tooth color change or tooth sensitivity incidence were found between the compared groups; however, tooth sensitivity intensity decreased when light sources were applied.

Conclusion:
The use of light sources for in-office bleaching is not imperative to achieve esthetic clinical results.

Authors: Faraj Nask Mohamad , A. Qadir Rebin 
Published: June 2018

The root-knot nematode incited by Meloidogyne incognita is one of the top diseases affecting tomato production worldwide. Nematicides can be effectively used to control the disease, but is costly and harmful to human life and environmental pollution. Alternatively resistant cultivars can be used inexpensive and eco-friendly. Resistance evaluation of five tomato cultivars (Red Rock, King Rock, Presto F1, Super Queen and Super Regina) were tested using randomized complete block design with five replications and three nematode inoculums (0, 500 and 1500 egg/second juvenile per pot). The statistical analysis gave significant differences among the genotypes, nematode densities level with their interactions. Among genotypes, Red Rock recorded significantly highest plant height (57.0) cm, Presto F1 (37.8) cm, King Rock (35.2) cm, Super Regina (30.1) cm and Super queen showed lowest (25.4) cm. As an alternative for managing the nematodes, further experiments are required in the field for applying plant resistances.

With the continuous development of facilities and horticulture, the area of vegetable planting in facilities increased year by year. Watermelon (Citrullus vulgaris Schrad) as the main cultivars within the facility, the continuous cropping problem is very serious, resulting in continuous cropping obstacles become increasingly obvious, the incidence of fusarium wilt increased year by year. Grafted watermelon roots developed to improve the growth of grafted roots of the conditions, resulting in robust plant growth. At the same time, the use of diﬀerent purposes of the rootstock can make watermelon in diﬀerent soil conditions under normal growth, such as the use of low temperature, drought, salt tolerance, barren and other characteristics of the rootstock. Secondly, the rootstock of the strong absorption of water absorption capacity, to promote the growth of grafted watermelon plants strong, large watermelon fruit, high yields. In addition, grafted watermelon seedlings grow fast early, for early maturing cultivation and overcome the seedless watermelon early growth slow defects is extremely favorable. So the use of pumpkin as a watermelon grafting rootstock, can eﬀectively improve the eﬀect of watermelon resistance to Fusarium wilts. And provide the theoretical basis and scientific basis for the further study of photosynthetic characteristics, disease resistance breeding and eﬀective control of watermelon. In this experiment, the watermelon varieties with diﬀerent resistance to fusarium wilt were selected, and the anti-fusarium wilt watermelon was studied systematically. There are changes in physiological characteristics during growth and development. In conclusion, grafting promotes the growth of watermelon and physiological characteristics of the index rose.
