Clinical case studies: are they still necessary?
Authors:   Burdenko National Medical Research Center for Neurosurgery, Moscow, Russia, Likhterman Leonid B.
Published: January 2022

Clinical case studies and the history of their emergence and development are analyzed. Evidence is provided for the risk of clinical case studies’ abandonment due to universal availability of medical imaging methods. Contribution of clinical case studies both to appropriate treatment tactics and to physician’s knowledge and experience is shown. In the context of preventive medicine, when the morphological substrate of the disease is detected in apparently healthy individuals, clinical case studies make it possible to perform preemptive surgery or to avoid it on a reasonable basis, thereby helping to resolve the situation of incidental findings to the benefit of the patient.
Current needs and new opportunities for glycemic control in type 2 DM. Focus on variability
Authors:   Pirogov Russian National Research Medical University, Demidova Tatiana Yu. , Ostroumova Olga D. ,   Russian Medical Academy of Continuous Professional Education, Moscow, Russia
Published: January 2022

Hypoglycemia associated with diabetes mellitus results in numerous types of microvascular dysfunction and increases cardiovascular risk in patients with DM of all ages. The glycemic control improvement results in substantially decreased risk of any diabetes-associated outcomes or microvascular complications. The most important parameters for type 1 and type 2 DM control used by clinicians are the components of the indicators “classic triad”: glycated hemoglobin (HbA1c), postprandial glucose (PPG), fasting plasma glucose (FPG). It appears increasingly necessary to teach diabetic patients to self-monitor blood glucose in order to achieve the target ranges of these indicators. In that regard, the patients have been helped by modern technologies.

Risks, urological complications and possible ways to overcome the COVID neuroinfection (clinical lecture)
Authors:   Sechenov First Moscow State Medical University (Sechenov University), Moscow, Russia, Borisov Vladimir V.
Published: January 2022

In patients with coronavirus infection, the nervous system involvement is very diverse. It undeniably directly affects the function of genitourinary system and other body systems. This can be most prominently manifested in urination, the complex and complicated process of bladder emptying. These symptoms are well-known and can be identified from the very first minutes of doctor-patient communication under the condition of knowledge about the symptoms and willingness for focused identification. Conscious control of urination requires complex interactions between the autonomic (sympathetic and parasympathetic) and the somatic nervous system. Medical history is important for diagnosis. On the one hand, the information obtained is twice as subjective, being the physician’s subjective assessment of the patient’s subjective perceptions. However, one should not forget about the need for individual approach to diagnosis taking into account each patient’s characteristics. Drug therapy should be accomplished only through the joint effort of urologist and neurologist during both therapy and rehabilitation.

X-ray computed tomography study for drill core of the Drazhnoe
orogenic-type gold deposit (Sakha (Yakutia), Russian Federation)
Authors: Chikatueva Victoria , Stepanov Nikita , Chitalin Andrey , Korost Dmitry
Published: January 2022

Orogenic gold-quartz deposits have a clear structural

control and are accompanied by wallrock metasomatic

alteration. However, in detailed modeling of such deposits,

there is often a mismatch between the structural

plans for high-grade ore zone distribution and metasomatite

zones, and the latter are not always associated

with faults. This is explained by the evolution of the hydrothermal

process and the pulsating nature of the development

of the territory. In the early stages of the mineral

deposit study, it is very important to reliably determine

the distribution of ore zones, since the correct targeting

of the drilling program and the economic deposit

assessment depend on it. The problem can be solved using

the method of X-ray computed tomography (СТ) in the

core study.

This paper presents the methodology of studying fullsize

core samples of gold deposits by using CT. A core

sample characterizing the central part of ore body of

Drazhnoye deposit (Tarynskoye ore field, Republic of Sakha

(Yakutia)) was used as the study material. The sample

studied was scanned by a SIEMENS Somatom Perspective

tomograph at two energies (80 and 130 keV). As

a result, a detailed three-dimensional stereological model

of the core was obtained, which made it possible not

only to study the distribution of ore minerals in the volume

of the entire sample, but also to identify vein bodies

of different ages, as well as to study their morphology

and trace the distribution patterns of ore mineralization

in them. Based on the study results, we can offer a

preliminary interpretation of ore mineralization and

vein formation sequence.

Published: January 2022

Rheumatoid arthritis (RA) is a chronic joint inflammatory disease that involves various pro-inflammatory mediators and cytokines. This study explores the correlation among various biochemical and immunological parameters for the male patients with RA and performs a predictive equation that would correlate these parameters together. The study involved 44 male patients suffering from RA with the same number of healthy controls. Consent was achieved for all patients and controls, together with a general examination including complete blood count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and RF. Moreover, lipid profile, kidney function tests, specific enzymes and the following parameters have been detected, which were hypothesised to negatively impact RA disease such as TGF-β1, vitamin E, VE-cadherin, interleukin 33 and TIMP-1. Various enzymatic-linked immunosorbent assays (ELISAs), spectroscopic, serological, and haematological methods were used to quantify these parameters. Our results have revealed a significant positive correlation between ESR, RF, VE-cadherin and vitamin E, specifically type α-tocopherol that are associated with the non-biochemical parameters such as BMI, waist length, hip length, thorax and age. The important parameters revealed correlated with RA were used to generate two predictive equations to help the physicians confirm whether a patient is diagnosed with RA directly. In addition, the study revealed some parameters that would have a positive effect on RA patients, such as TGF-β1, vitamin E and VE-cadherin, which have shown a decrease in their values compared to the controls. In contrast, other parameters showed an increase in RA patients, and therefore they can be useful biomarkers for RA disease.

Published: January 2022

The revolution of Malaysian Construction 4.0 through emerging technologies has brought a paradigm shift that has digitalized the construction sector. There is a need to adopt a computerized protocol to assist in automating the performance of a contract to meet future digital challenges. Therefore, this paper aims to serve as a pioneer study to investigate the implementation of the Malaysian construction industry to adopt smart contracts. This study adopted a qualitative scientific methodology, whereby a systematic review was conducted to gather the benefits and challenges of implementing smart contracts in the construction industry. Further, interview sessions were arranged to collect data from the construction contract management experts. The research findings unveil that due to the self-executing attribute of smart contracts, the implementation of smart contracts could provide a better apportionment of risks in a contract. The study also finds that the challenges in implementing smart contracts are severe. For instance, the smart contract is irreversible and immutable and prone to human error. The study concludes that it is more suitable to apply and implement a smart contract to a short-term contract that is not subjected to variation. Furthermore, a smart contract can enhance the efficiency in managing the contracts, such as reducing time and managing the conflicts and disputes that arise during the contract duration. The developed implementation framework is significant for the construction personnel, especially those dealing with the contract administration. The implementation of smart contracts in construction could boost contract administration and management discipline via investment in this new technology.
Compression and Flexural Behavior of ECC Containing PVA Fiber
Authors: Siong Wee Lee , Md Zain Mohd Raizamzamani , Chai Lian Oh , Saari Nadiah , Yahya Norrul Azmi
Published: January 2022

Research on Engineered Cementitious Composites (ECC) is overwhelming owing to its wide structural applications that can serve multi-functional purposes in civil and nvironmental infrastructures. Compared to other high-performance fiber reinforced concrete, ECC yields superior tensile ductility and multiple cracking behaviors when subjected to tensile loadings even with low to moderate volume of fibers. This paper presents the flexural properties of ECC made of cement, an industrial by-product, such as ground granulated blast-furnace slags (GGBS), local silica sand, polyvinyl alcohol (PVA) fiber, water, and superplasticizer (SP). Two series of ECC mixtures (ECC-G50 series and ECC-G60 series) and one control mixture were designed. The effect of two different fiber contents in volume fraction was investigated for the two series of ECC mixtures. The compression and flexural tests were conducted on ECC and control specimens after 28 days of curing. A compression test revealed that almost all ECC mixtures improved compressive strength between 20% to 30% compared to the control specimens. In addition, all ECC plate specimens demonstrated excellent strain-hardening states (i.e., displacement capacity at least ten times greater than the control specimens) and multiple fine-cracks failure modes after the three-point bending test. The increase in fiber content slightly reduced the compressive strength but enhanced the flexural behavior of the ECC-G50 series. However, this observation is not discovered in the ECC-G60 series. Outcomes of this research assist material scientists on the content of PVA fiber and GGBS used in making ECC.
Effect of Water Absorption on Flexural Properties of Kenaf/Glass Fibres Reinforced Unsaturated Polyester Hybrid Composites Rod

Published: January 2022

This study investigates the effect of water absorption on the flexural strength of kenaf/ glass/unsaturated polyester (UPE) hybrid composite solid round rods used for insulating material applications. Three volume fractions of kenaf/glass fibre 20:80 (KGPE20), 30:70 (KGPE30), and 40:60 (KGPE40) with three different fibre arrangement profiles of kenaf fibres were fabricated by using the pultrusion technique and were aimed at studying the effect of kenaf fibres arrangement profile and its content in hybrid composites. The fibre/ resin volume fraction was maintained constant at 60:40. The dispersion morphologies of tested specimens were observed using the scanning electron microscope (SEM). The findings were compared with pure glass fibre-reinforced UPE (control) composite. The water absorption results showed a clear indication of how it influenced the flexural strength of the hybrid and non-hybrid composites. The least affected sample was observed in the 30KGPE composite type, wherein the kenaf fibre was concentrated at the centre of a cross-section of the composite rod. The water absorption reduced the flexural strength by 7%, 40%, 24%, and 38% of glass/UPE (control), 20KGPE, 30KGPE, and 40KGPE composites, respectively. In randomly distributed composite types, the water absorption is directly proportional to the volume fraction of kenaf fibre. At the same time, flexural properties were inversely proportional to the volume fraction of kenaf fibres. Although the influence of water absorption on flexural strength is low, the flexural strength of pultruded hybrid composites was more influenced by the arrangement of kenaf fibre in each composite type than its fibre loading.

Computational Fluid Dynamic Analysis of Vortex Generators on MAV.
Authors: Raghavender Vadla , Vatte Priyanka , Varun V , Reddy M. Pala. Prasad
Published: January 2022

Micro Vortex generators are very small components deployed on the wings to control airflow over the upper surface of the wing to affect the boundary layer over it. These are employed onto a Micro aerial vehicle (MAV) of fixed wing type with an S5010 which is a low Reynolds number airfoil. This airfoil provides good aerodynamic results as compared to many low Reynolds number airfoils. Micro vortex generators are used to enhance the performance through controlling airflow at different speeds and angle of attack.

The comparison of a half part of the MAV wing which is designed in CATIA, with and without the vortex generators on its leading edge at 10% of its chord length is done to show how the vortex generators improve the performance and control authority at different speeds and angle of attacks. These are shown with the velocity and pressure distribution around the wing by considering laminar flow in the simulation.

Deer Use of a Right-of-Way in Central Pennsylvania, U.S.
Authors: Yahner Richard
Published: January 2022

The purpose of the State Game Lands (SGL) 33 Research and Demonstration Area, since its inception in 1953, has been to compare the effectiveness of commonly used mechanical and herbicidal maintenance treatments on vegetation and wildlife on a right-of-way (ROW). White-tailed deer (Odocoileus virginiana) use of the SGL 33 Research and Demonstration Area, Center County, Pennsylvania, U.S. was reported over 20 years ago. As part of a 2-year study before and just after maintenance of the SGL 33 ROW, I examined deer use of the ROW in 2006 to 2007. Deer can have a positive impact on a ROW by browsing on undesirable trees (those capable of growing tall) in wire and border zones of a ROW and providing aesthetic value to a ROW; however, deer can have a negative impact on adjacent forest health by feeding on herbaceous and woody vegetation. In this study, I determined relative use by deer of the ROW, which is maintained by the wire-border zone method and using integrated vegetative management. Deer use of the ROW in 2006 to 2007 was minimal, which I attribute primarily to the lack of grass cover type as a food resource.
Forces and Stresses Generated During Rigging Operations
Authors: Kane Brian , Brena Sergio , Autio Wesley
Published: January 2022

Rigging is one of the most dangerous aspects of arboriculture, yet there are no robust studies of the forces and stresses generated during rigging. Compounding the inherent danger of rigging is the structurally-deficient condition of many trees that are removed using rigging. Red pines (Pinus resinosaAit.) (n= 13) were removed using conventional techniques, and forces at the block and in the rope were measured as the top, and four subsequent pieces were rigged with a block and Port-A-Wrap. Stress in the trunk at breast height was calculated from strain measurements and each tree’s modulus of elasticity. Multiple regression was used to determine which independent variables (mass of piece, fall distance and fall ratio, notch angle and depth) best predicted forces. Tops and pieces exhibited different relationships with mass, which was the best predictor of force at the block and tension in the rope. Other variables were not as important and exhibited counter-intuitive relationships with forces. There were few differences in stress generated when removing tops and pieces, which appeared to be due to greater deflection higher in the trunk when tops were removed.

Published: January 2022

A random 10% sample of communities in highly-impacted counties from the 2004 and 2005 Florida, U.S. hurricane seasons were used to study tree debris generation and damage from seven hurricanes. Woody debris amounts in cubic meters (m3) (cubic yards; yd3) as well as rates and costs for cleanup, tree removal and pruning were obtained for these events. Average debris generation per 30.5 m (100 ft) of street segment ranged from 0.59 m3(0.77 yd3) for low damage, 3.4 m3(4.44 yd3) for moderate damage, and 17.47 m3(22.85 yd3) for high damage levels; cost of removal and disposal averaged $28.25 per m3($21.47 per yd3). Most communities used unit costing to account for tree removal and pruning rates, averaging 2% and 28% of street trees, respectively. Tree canopy, wind speed, and percentage of urban developed land all had a significant effect on debris amount. Florida communities with a greater tree density generated decreased amounts of debris during the 2004 and 2005 hurricane season. These results can be used to help communities plan for hurricane management activities and estimate potential damages to their tree resource.
Relative Growth and Water Use of Seedlings from Three Italian Quercus Species
Authors: Struve Daniel , Ferrini Francesco , Fini Alessio , Pennati Laura
Published: January 2022

A species’ water use characteristics and growth habits are important to urban foresters. Seedlings from three species (and two sources)—Quercus cerris L., Q. pubescens Willd., and Q. robur L.—were container-grown and subjected to a three day water use trial under nonlimiting soil moisture conditions. Water use varied among species and between sources within a species. Larger seedlings used more water than smaller seedlings; Q. robur seedlings were the tallest, 70.5 cm (27.8 in), and had the greatest water use seedling, 73.4 g (2.5 oz) water, while Q. pubescens and Q. cerris seedlings were shorter, 46 and 45 cm (18.1 and 17.7 in), and averaged 47.5 and 44.9 g (1.68 and 1.58 oz) water, respectively. Quercus pubescens seedlings had the highest water use cm-2 leaf area (0.111 g); Q. cerris seedlings had the highest height-adjusted water use (1.4 g water cm-1 height). There were significant differences in water use between sources within species. Principal component analysis, using 20 variables, showed that seedlings of Q. robur and Q. pubescens sources clustered while seedlings of the two Q. cerris sources were separate from each other and the Q. robur and Q. pubescens sources. The clustering reflected the proportionally greater distribution of dry weight to shoot growth and correspondingly less to root growth of the Q. robur and Q. pubescens seedlings, than that for Q. cerris seedlings. The results are related to the species’ relative value to nursery producers and to the potential value to urban forest managers and the potential for cultivar development.
Tree Care and Topping Beliefs, Knowledge, and Practices in Six Western U.S. Cities
Authors: Kuhns Michael , Reiter Douglas
Published: January 2022

A survey of households was conducted in six cities in the interior western United States to determine homeowners’ knowledge of tree biology and tree care and their knowledge and practice of topping. Tree biology and tree care knowledge was low, depending on the specific subject, and few respondents had any formal training in tree care. Respondents’ topping knowledge was moderate to poor if they had topped trees before, regardless of whether they received a topping-related educational brochure. Those who had not previously topped trees were fairly knowledgeable and the brochure increased knowledge in some cases. Topping was fairly commonly practiced, even by those who cared about trees, and often was done for safety and to improve tree appearance and tree health. Amongst those who had topped trees, the survey explored who performed the topping, why it was done, and their satisfaction with the practice. Examples of ways the tree care industry and others may be contributing to misunderstanding, such as inconsistent practices, are discussed. Recommendations are made for changing knowledge and attitudes about tree care as well.
Carbohydrate Injections as a Potential Option to Improve Growth and Vitality of Live Oaks
Authors: Martínez-Trinidad Tomás , Watson W. Todd , Arnold Michael , Lombardini Leonardo , Appel David
Published: January 2022

This study evaluates the effects of carbohydrate injections on the growth and vitality of live oak (Quercus virginiana P. Miller). Glucose, sucrose, or a 50:50 mixture of both carbohydrates at increasing concentrations [0, 40, 80, and 120 g/L (0, 5.3, 10.6, and 16.0 oz/gal)] were injected into live oaks. Trunk and root growth, net photosynthesis, root and twig carbohydrate concentration, and chlorophyll fluorescence were monitored. Isotope composition of twig and root samples was measured as an indicator of injected carbohydrate distribution. There were significant differences (P < 0.05) in trunk growth among types of carbohydrates, but no significant differences for carbohydrate concentrations. The mixtures of sucrose and glucose had the largest effect on growth compared to either sugar alone, suggesting that glucose and sucrose alone were used in processes other than trunk growth. 50:50 mixtures caused a greater effect on overall mean growth indices than either sugar alone. Glucose content in twigs and starch in roots were significantly different (P < 0.05) among overall means for concentrations with increased levels found in trees treated with the greatest concentrations. Chlorophyll fluorescence Fv/Fm revealed highly significant differences (P < 0.001) among overall concentrations. Carbon isotope values did not reveal a definite trend that corroborated the exogenous carbohydrate distribution. Results from this experiment suggest that carbohydrate trunk injections can have an impact on growth and vitality of live oak.
Pressurized-Canister Trunk Injection of Acephate, and Changes in Abundance of Red Elm Bark Weevil (Magdalis armicollis) on American Elm (Ulmus americana)
Authors: Booth Michael , Johnson Dan
Published: January 2022

Portable pressurized injection vials (Ecoject System) were used in an experiment to assess injection of acephate into elm trees (Ulmus americana) as a means of reducing within-tree abundance of red elm bark weevil (REBW), Magdalis armicollis. A total of 25 elm trees were treated, each paired with an untreated tree. A total of 400 pressurized canisters were used in the study. REBW population density, as indicated by sticky-paper trap catches, on treated and untreated trees did not differ significantly at the time of trunk injection. Two weeks after injection, the average REBW trap catch on the 25 untreated trees had increased, whereas the average trap catch on the 25 treated trees had decreased. The resulting average trap catch from the treated trees was significantly lower than that of the control trees. Although subsequent declines in REBW populations precluded a longer record of the effects of tree injection, the significant reductions apparent in the first two weeks following injection indicated the method was effective in reducing REBW abundance. The impact on REBW populations was detectable even though treated and untreated trees were contiguous, indicating that selective treatment of individual trees could be part of an effective operational treatment for REBW management. No phytotoxic effects were detected by spectrophotometric assessment of leaf chlorophyll.

The aim of this work was to investigate the drought tolerance of different Tilia species and of different cultivars of Acer platanoides grown during the establishment phase, and to evaluate irrigation effect on their growth and physiology. In winter 2004–2005, 168 trees [8–10 cm (3–4 in) circumference] of Tilia platyphyllos, T. cordata, T. × europaea, T. tomentosa, Acer platanoides ‘Summershade’, A. platanoides ‘Deborah’, and A. platanoides ‘Emerald Queen’ were planted in the field. Eighty-four plants were irrigated with a drip irrigation system (4 l/h) and eighty-four were not. Height, trunk diameter, and shoot elongation were measured at the end of the growing season in 2005, 2006, and 2007. Leaf gas exchange and chlorophyll fluorescence were measured monthly during the 2006 and 2007 growing seasons. Leaf greenness index content was measured in 2006 and 2007. Results indicate that T. tomentosa and T. cordata are more drought tolerant during establishment than T. platyphyllos, while Acer platanoides ‘Summershade’ is less drought tolerant during establishment than the cultivars ‘Emerald Queen’ and ‘Deborah’.
Threshold value estimation of journey-distance using generalized polynomial function
Authors: Subhojit Roy
Published: January 2022

The present work demonstrates an experience in estimating the threshold value of journey distances travelled by transit passengers using generalized polynomial function. The threshold value of journey distances may be defined as that distance beyond which passengers might no more be interested to travel by their reported mode. A knowledge on this threshold value is realized to be useful to limit the upper-most slab of transit fare, while preparing of a length-based fare matrix table. Theoretically, the threshold value can be obtained at that point on the cumulative frequency distribution (CFD) curve of journey distances at which the maximum rate of change of the slope of curve occurs. In this work, the CFD curve of the journey distance values is empirically modelled using Newton’s Polynomial Interpolation method, which helps to overcome various challenges usually encountered while an assumption of a theoretical probability distribution is considered a priori for the CFD.
Road Safety Resource Allocation Using Interactive Multiobjective Optimization
Authors: Augeri Maria Grazia
Published: January 2022

A model is proposed for allocating safety resources to various hazard sites. Due to budget constraints, allocation of resources for necessary countermeasures is a critical issue in safety improvement programs. Therefore, the Decision Maker needs a tool that can prioritize the identified countermeasures looking at several objectives, the most important of which are: reducing the number of accidents and minimizing the costs. A number of countermeasures could be implemented simultaneously in the same location and this was considered, so that the solution that best optimizes the objectives was selected. Since the considered objectives are not commensurable, a new methodology with interactive multi-objective optimization in the case of 0-1 integer variables was proposed, based on the application of a logical preference model built using dominance-based Rough Set Approach (IMO-DRSA). Finally, an application of the methodology is presented considering a sample of Italian urban intersections and a set of mutually exclusive alternatives at each location.
