Potassium–calcium antagonistic interaction under tomato magnesium deficiency and magnesium fertiliser regulation in solar greenhouse
Authors: Yan B. , Sun Y.Y. , Wei Y. 
Published: August 2020

This study sought to clarify the antagonistic interactions of potassium (K) and calcium (Ca) to magnesium (Mg) under a deficiency of Mg in tomato. Tomato leaves and soil samples that had differing levels of Mg deficiency were collected to study the relationship between symptoms of Mg deficiency and contents of soil K and Ca. Four different Mg fertiliser treatments were conducted to analyse the regulation of Mg for soil K, Ca and Mg. The results showed the following: (1) The yield of tomatoes decreased significantly with an increase in Mg deficiency, and the yield of tomatoes with moderate (MD) and severe (SD) Mg deficiency decreased by 38.02% and 59.53%, respectively, compared with treatments without Mg deficiency (ND). (2) The cation saturation ratio of K+ (CSRK+) was significantly higher with MD and SD compared with ND, while the CSRMg2+ was lower. The soil K/Mg and Ca/Mg values were higher than the critical value of imbalance. (3) The soil exchangeable K, CSRK+, Ca/Mg and K/Mg under SD increased significantly when compared with that under ND. (4) The content of Mg in tomato leaves and its yield were significantly negatively correlated with soil exchangeable K, CSRK+ and K/Mg. (5) With the increase in application of Mg fertiliser, the soil exchangeable K content, K/Mg and CSRK+ decreased significantly, while the Ca/K increased. The soil exchangeable K content, K/Mg and CSRK+ with 90 kg/ha MgSO4 and 234 kg/ha K2O applied (M2K1 treatment) were the lowest among all treatments. (6) The yields of tomatoes and uptake of Ca and Mg increased as supply of Mg increased. (7). Reducing the application of K was a much more efficient way to decrease soil K/Mg and restore cation imbalance than providing Mg fertiliser in calcareous soil.

Published: August 2020

Using bioinspired models and methods is one of approaches for solving tasks of swarm robotics. In this paper one of such tasks, modeling of foraging, and it’s solving by creating analogues of social structures of ants and models of feeding behavior are considered. The most important characteristics of ants’ colonies for modeling were defined – individuals number in society and it’s structure, workers’ speed, a communication distance and working area size. Besides, existing experimental basis (a group of robots and a polygon) was estimated for a usage as a hardware platform for experiments. Several models of feeding behavior were considered: a model without foragers’ functions differentiation and a model with differentiation on active and passive ones. Active foragers look for resources by themselves, then they involve passive foragers; passive foragers are settled on a base, while are not involved in harvesting.
A set of finite state machines describe the behavior of agents: basic automatons (provide basic behavior functions) and a meta- automaton, that switches with some conditions an execution of basic automatons. Basic movements were tested on experimental basis. A complex test of models were conducted in a simulation program Kvorum. An analogue of real polygon was made in the program. Modeling consists of series of experiments for every model in which agents must harvest resources. Series differ from each other by number of agents. For models’ quality estimation a ratio of received energy to average obtaining time. Experiments settle that model with functions differentiation works more effective.

Background and Aim: Tinnitus can affect daily life. The evaluation of the affected aspects of life quality is highly dependent on the sub­jects’perception. Self-report questionnaires have been used to identify these affected aspects. In the present study, the relationship between the Persian versions of tinnitus functional index (TFI-P) and tinnitus handicap inventory (THI-P) was investigated.
Methods: This is a comparative cross-sectional study conducted on 28 hearing-impaired and 27 normal hearing subjects with tinnitus in aged 18−60 years selected according to the inclusion criteria. Both groups completed the TFI-P and THI-P.
Results: There was a significant and relatively strong relationship between the total scores of THI-P and TFI-P (r = 0.65) and also between the emotional subscale of TFI-P and the cata­strophic subscale of THI-P (r = 0.73). More­over, there was a moderate relationship between age factor and total score of TFI-P (r = −0.32), and between the cognitive subscale of TFI-P and age (r = 0.40). However, no significant difference was found between hearing-impaired and normal hearing subjects in terms of the total score and subscale scores of TFI-P. Fur­thermore, we found a significant difference bet­ween female and male subjects in terms of the relaxation subscale of TFI-P, and between dura­tion of tinnitus and the quality of life subscale (r = 0.33).
Conclusion: The scores of the THI-P and TFI-P questionnaires are related to each other and they can be used for measuring the negative effects of tinnitus.

Published: August 2020

Background and Aim: Auditory rehabilitation is an essential step after hearing aid fitting for children with hearing loss. The aim of this study was to evaluate the auditory rehabilitation results based on auditory verbal therapy approach in children with severe to profound sensory-neural hearing loss. Auditory verbal therapy is a popular approach for rehabilitation children with hearing loss.
Methods: This is a retrospective study that eva­luates the results of auditory rehabilitation of 19 children with severe to profound hearing loss. Most children were about three years old at the beginning of the rehabilitation process. They were received bilateral hearing aid and auditory rehabilitation based on auditory verbal therapy (AVT) approach. Each case progress was meas­ured by Newsha developmental scale.
Results: All of the children showed progress during the AVT program (p < 0.05). The Newsha developmental scale showed that hearing and receptive language categories had more progress. The progress was similar between male and female participants and there was no difference in all of categories (p > 0.05).
Conclusion: The AVT approach is beneficial for rehabilitation of older children with bilateral sev­ere to profound sensory-neural hearing loss. The progress was observed in all categories of Newsha developmental scale.

Assessment of CT Imaging Protocols Impacts on Calculation of Point Dose in Water Phantom Using Radiotherapy Treatment Planning System
Authors: Fallah Mohammadi Gholamreza , Mihandoost Ehsan 
Published: August 2020

Purpose: Point dose calculation in the Treatment Planning System (TPS) is performed using Computed Tomography (CT) images because CT images data have the tissue electron density information. The effect of CT imaging protocols on the calculation of point doses in TPS is one of the most important subjects that was evaluated in this study.
Materials and Methods: CT scan imaging was performed from cylindrical water phantom using three scanner systems and different imaging technical parameters. The CT images data were irradiated in TPS to delivering a 200 cGy radiation dose to the center of the phantom with 6 and 15MV X-Ray photon energy with multiple radiation fields and Monitor Unit (MU) were separately calculated. In the TPS, a virtual water phantom with the same characteristic as CT image phantom was simulated and irradiated with similar conditions. The difference in MU values obtained from two irradiation methods in TPS was compared with Wilcoxon nonparametric test.
Results: Variations of mA, kV, Pitch, slice thickness, and kernel as CT imaging parameters have not significantly affected radiotherapy point dose calculation (<2%). CT imaging protocols as a thin slice, 80 kV, and sharp kernel have the greatest difference between CT image-based calculation and designed phantom calculation in TPS where wedge field and 6 MV photon energy were used.
Conclusion: The use of CT images obtained with multiple protocols can be used without having a significant effect on the dose calculations of the treatment planning system.

An experimental assessment has been made of the influence of electro-erosive modification modes for worn working surface of an cutter on the restoration of its cutting ability. The paper provides basic information on dental cutters. The provisions of the experimental research methodology are described, including a description of a device for modifying the worn surface of a dental cutter and a device for determining its cutting ability. Experimental data are presented and analyzed that reflect an effect on restoration of a cutting ability of a worn surface of a dental cutter, voltage of a storage capacitor and number of holes applied to it during its modification. Rational modes of modifying a worn-out surface of a dental mill that provide the greatest recovery of its cutting ability have been determined in the paper. It has been shown that with increasing voltage, the energy of the electric discharge acting on the treated surface increases, which leads to the formation of a single hole of a larger size on it, including metal flows along its edge that extend beyond the initial contour of the worn cutter teeth. These metal flows on the modified surface of the cutter play the role of peculiar cutting and deforming elements. It has been revealed that in the process of modifying the worn surface of the cutter, it is necessary to ensure that there is no overlap of the holes formed on it, i.e. the distance between the centers of adjacent holes should be greater than or equal to the size of metal deposits at their edges. In this case, the metal flows retain their original shape and have the highest height at these pulse parameters, which ensures a higher cutting ability of the modified cutter surface than when the holes are overlapped.

A large variety of machine operating conditions leads to a difference in the wear rate even for their units being of the same type. Operational time terms of single-type units and machines are not the same, and therefore, numerical expressions of operational reliability will be probabilistic values. Incomplete restoration of original properties of a unit, a negligent repair, a poor maintenance usually lead to the fact that any of several parts independently one from another can determine reliability of a machine (a unit). This is especially important to consider when manufacturing packaging in order to avoid rejects. The operational reliability of modern machines consisting of hundreds, and sometimes thousands of parts, wear processes of which are in a complex relationship, depends on a number of factors. A study on reliability of main components and equipment devices is an urgent task. Successful operation of printing equipment is possible only if there is a clear organization of preventive work, ensuring preparation of printing machines for printing and post-printing processing. High-performance equipment, such as die-cutting presses, should be regularly inspected, adjusted and maintained in such a way as to obtain standard results at the output. The paper has studied reliability of main components and devices of die-cutting presses based on calculation of failure probability. Calculations have been carried out by analogy with the calculation of the probability of events in the fault tree. Failure diagrams of devices and units of die-cutting presses have been built in the paper. Based on the analysis of the failure probability for main components and devices, graphs of residual life for equipment operation on its life cycle have been constructed in the paper.
Technology Focus: Wellbore Tubulars (July 2020)

Why steel casing or tubing? What does that choice have to do with sustainability? Is it time to change? These are a few of the questions we need to think about to move from the status quo, and we need to use technology, engineering, and innovation to reduce not only the surface footprint but also the downhole footprint.
Composites are making inroads and continue to replace steel in other industries such as aerospace, automotive, and the renewable-energy segment. The follow-up question is, “Is it sustainable and relevant to our industry under harsher and deeper environments?” Different types of components exist, including reinforcement and the matrix, that can be adjusted and modified to be used for downhole conditions without compromising well integrity.
There are compelling answers to those questions. Composites have high strength-to-weight ratios that result in low weight and high energy absorption. They have high stiffness and high durability, including corrosion resistance, less fracture toughness, and dimensional stability. Added distinctive advantages of composites are that they are excellent electric and thermal insulators.
On the other hand, there are challenges very specific and unique to our industry such as anisotropic properties, modulus matrices, ability to with-stand thermomechanical loading, unknown stress/strain under tension/compression, unknown failure envelopes under internal pressure, bending loads, external pressures, tensile loads, and torsional load conditions. Addition-al challenges include material-properties degradation under wear conditions and composite-to-metal joining if necessary. For this, a phased approach may be necessary. Development of new products will require conservative design consisting of modeling with improved physics and improved models with experimental results involving compression state, buckling, and collapse for various slenderness ratios. Nonetheless, we are making inroads with composites.
Looking to the future and considering sustainability, switching to composite casings in the coming years is necessary. I have selected papers that are structured toward using composites and, to some extent, answering the questions I have raised.
SPE Strong: Strengthening Our Core: SPE Strong: Getting Stronger

Published: August 2020

I am both sad and joyous that this will be my last JPT column as your SPE President. I am sad because this signals that my journey as president is concluding, and I am joyous because the time it took to write these columns can be put toward other ambitions such as improving my golf game or my skeet skills. Trust me, those items are in dire need of improvement!
Members often ask me if I am disappointed with how the latter portion of my presidency was affected by the pandemic and the crash of oil prices. To be honest, I am not disappointed. I was able to visit many sections as President-Elect and speak at many events; however, the role of SPE President is much greater than that. This time was critical to serve as chair of the SPE Board and guide our society through an inflection point, requiring us to anticipate how to deliver on our mission to our members in a post-pandemic world. Compounding the complexity is SPE’s worst financial crisis in its history due to mass event cancellations, postponements, and loss of sponsorships. If ever there was a time to lead the society through an unprecedented challenge, it is now. I am grateful to be at the helm during these times. With a resilient board of directors and dedicated SPE staff by my side, I am eager to help steer SPE out of these very rough waters. Ironically, many board and staff members became closer while working remotely. We were able to “visit” one another’s homes during our calls, see each other’s casual attire, and even “meet” a few wandering pets who occasionally appeared onscreen.
When I accepted the presidential gavel at the conclusion of the 2019 ATCE, I challenged the board committees, SPE staff, and our members to strengthen five core areas of our society as part of a campaign I called “SPE Strong.” The phrase and its adaptation “SPE Stay Strong” have been used in messaging hope and guidance to our members.
As I am writing this, I still have approximately 4 months left in my presidency and nearly 1.5 years on the board to accomplish all my goals. However, I will use this opportunity to share the status of each goal and the pandemic’s impact on it.
Strengthen the Quality of our Technical Content
While I raised the issue of technical quality in our offerings, there were some initiatives already underway. More program committee members are taking responsibility for working with authors to improve the quality of papers and presentations prior to publication. We are now able to track the number of papers flagged for recommended revision, which will serve as a benchmark for monitoring progress on quality improvement.
