В настоящее время актуальной задачей является поиск экологически безопасных и экономически доступных источников энергии для многоцелевого использования. Одним из таких ресурсов является многолетнее растение из семейства Мятликовые – мискантус гигантский (Miscanthus giganteus), который отличается значительным нарастанием надземной массы по С4-фотосинтезу, но не может реализовать свои потенциальные возможности как культура с высокими темпами фотосинтетической деятельности, поскольку в год посадки слабо конкурирует с сорняками. Поэтому изучали способы борьбы с сорным компонентом в агроценозе мискантуса на светло-серой почве коллекционного участка ФГБОУ ВО Пензенский ГАУ. В годы проведения исследований, характеризующихся различными гидротермическими условиями (ГТК 0,64-1,29), установлено, что гербициды системного действия Балерина и Магнум по фону Торнадо 500 способствуют увеличению площади листовой поверхности мискантуса в первый год жизни до 18,36…19,09 тыс. м2/га, фотосинтетического потенциала до 496,1…508,7 тыс. м2∙сут./га. Максимальные показатели чистой продуктивности фотосинтеза 0,62…0,85 г/м2∙сут. отмечены в конце июня. За счет двукратной химической прополки снижение засоренности ведет к получению максимальной урожайности надземной массы 8,92…9,09 т/га. Наибольший сбор сухой массы 2,13…2,97 т/га получен при использовании Торнадо 500 в сочетании с гербицидами Балерина и Магнум.
Currently, an urgent task is to find environmentally friendly and economically accessible energy sources for multi-purpose use. One such resource is a perennial plant from the bluegrass family, Miscanthus giganteus, which has a significant increase in above-ground mass by C4-photosynthesis, but cannot realize its potential as a crop with high rates of photosynthetic activity, because in the year of planting it competes poorly with weeds. Therefore, we studied ways to control the weed component in the agrocenosis of miscanthus on the light gray soil of the collection area of Penza State Agrarian University. In the years of the research, characterized by different hydrothermal conditions (HTC 0.64-1.29), it was found that the herbicides of systemic action Balerina and Magnum in the background of Tornado 500 contribute to an increase in the leaf area of miscanthus in the first year up to 18.36...19.09 thousand m2/ha, in the photosynthetic potential to 496.1...508.7 thousand m2∙day/ha. The maximum values of net productivity of photosynthesis (0.62...0.85 g/m2∙day) were observed at the end of June. Due to the double chemical weeding the decrease of weeds leads to the maximum yield of above-ground mass - 8.92...9.09 t/ha. The highest dry matter yield of 2.13...2.97 t/ha was obtained using the Tornado 500 in combination with the herbicides Balerina and Magnum.

Objective: Radiation dose to pediatric patients have been widely reported, it is however necessary that imaging expert keep doses as low as possible to forestall stall long term cancer risk. This study is aimed at determining pediatric entrance surface dose (ESD), 75th percentile ESD, absorbed dose (D) and effective dose (E) for 0-15 years.
Material and Methods: The study used a digital radiography (DR) unit with a grid system for each chest X-ray. The thermoluminescent dosimeter (TLD) used was encapsulated in transparent nylon, it was then attached to the patient skin (chest wall) and the second was placed directly at the posterior end of it.
Results: The mean ESDs for the 4 age groups were as follows: 0- < 1 (1.54±0.74mGy), 1- < 5 (1.53±0.83mGy), 5- < 10 (0.55±0.39mGy) and 10- ≤15 (1.30±0.57mGy), with an overall mean of 1.23mGy. The 75th percentile ESD for each age group above 10 patients (excluding 5- < 10yrs) was 2.18, 2.19 and 1.75mGy respectively. The absorbed dose (D) ranged from 0.03-2.39mGy. The mean effective dose (E) for the 4 age groups was 0.18±0.03mSv. There was a good correlation between ESD and D (P = 0.001). A One-Way ANOVA shows that the field size and focus to film distance (FFD) affected the ESD and D (P < 0.001) respectively. The risk of childhood cancer from a single radiograph was of the order of (1.54-23.4) ×10-6.
Conclusion: The 75th percentile ESD, E and childhood risk of cancer was higher than most studies it was compared with. The study reveals that machine parameters such as the field size and FFD played a major role in dose increase. Protocol optimization is currently needed for pediatric patients in the studied facility.

Our Nephrology Department during the spring period on the first wave of COVID-19 was the referral Dialysis Unit for Covid-19 positive HD patients in the district area of Athens, Greece. This study aims to report the characteristics, rates, and outcomes of all patients affected by infection with SARS-CoV-2 undergoing HD and treated under our care. 22 Covid-19 positive HD patients were treated under the care of our facility during the period 8 April 2020-17 June 2020. 16 patients were symptomatic at admission and 13 patients were admitted with or developed during their stay pleural effusions. 12 patients (8 male) of our group died during their hospitalization. The mean age of our patients was 74.5 years. It has to be pointed out that 13 patients were over 75 years old. Mean age was higher in those who died compared with those who were discharged with double negative Covid-19 tests (79 vs 74,5 years old respectively). It seems that despite the fact that the immune response of this population has not been clearly clarified, age comorbidities and above all end-stage renal disease by its self is a significant and unpredictable risk factor for clinical outcome of HD patients with COVID-19 infection.

. In this paper we discuss the theoretical principles the method of design characteristics optimization of high-speed passenger catamarans. The goal of the paper is to determine the role and place of the proposed method in the development of sea passenger traffic and island tourism in the Socialist Republic of Vietnam and to illustrate its capabilities in relation to the interests of different participants of process. As a rule, the existing ships are purchased on the secondary market, and new ones are often designed and built at foreign shipyards. This is a reason to develop the design methods that take into account the regional characteristics of Vietnam. The novelty of this research is based on the fact that the proposed method takes into account the regional features, combines mathematical and optimization models of various design levels and allows to take into account the interests of participants of a program for development of maritime transport infrastructure and tourism in Vietnam. The theoretical principles of ship theory, ship design, mathematical programming and statistics were used for the method development.
In this paper we present the results of design characteristics optimization of high-speed passenger catamarans and comparative analysis of these results with the main dimensions of modern high-speed passenger catamarans. The proposed method can be used in the design and assessment of the economic efficiency of high-speed passenger catamarans. The results can be used in Vietnam government program oriented to development of sea transport infrastructure and tourism.

Published: March 2021

It is common to find multiple network interfaces connected to different Internet Service Providers (ISPs) in devices such as smartphones. Multipath TCP (MPTCP) enables TCP connections to use all these network interfaces in a single TCP connection in an application transparent manner. MPTCP schedules traffic of one TCP connection over subflows created over these network interfaces. It is evident that this requires some scheduling policy. There have been some attempts to allow applications to decide on the scheduling policy. However, this violates the application transparency of MPTCP, and applications do not have all the information required to decide on such a policy. In addition, this allows the applications to monopolize the network connection thus posing a security threat as well. We argue that only the owner of the device (the user) has the right to make that policy decision and only the user can make an informed decision on the scheduling policy. For example, the user has the information on the monetary cost of the connections through different interfaces. In this paper we present a mechanism that allows the user to provide hints to the TCP scheduler to alter its scheduling policy. While this is not a mechanism to implement generic scheduling policies, it demonstrates how a user can guide the scheduling policies. As a proof of the concept, we demonstrate how MPTCP scheduler can be influenced to select a less stable and lossy path over a stable path based on a user preference.

Context
Hypertrophy of the infrapatellar fat pad (IFP) in idiopathic knee osteoarthritis has been linked to deleterious synovial changes and joint pain related to mechanical tissue impingement. Yet little is known regarding the IFP's volumetric changes after anterior cruciate ligament reconstruction (ACLR).

Objectives
To examine changes in IFP volume between 6 and 12 months after ACLR and determine associations between patient-reported outcomes and IFP volume at each time point as well as the volume change over time. In a subset of individuals, we examined interlimb IFP volume differences 12 months post-ACLR.

Study Design
Prospective cohort study.

Setting
Laboratory.

Patients or Other Participants
We studied 26 participants (13 women, 13 men, age = 21.88 ± 3.58 years, body mass index = 23.82 ± 2.21 kg/m2) for our primary aims and 13 of those participants (8 women, 5 men, age = 21.15 ± 3.85 years, body mass index = 23.01 ± 2.01 kg/m2) for our exploratory aim.

Main Outcome Measure(s)
Using magnetic resonance imaging, we evaluated the IFP volume change between 6 and 12 months post-ACLR in the ACLR limb and between-limbs differences at 12 months in a subset of participants. International Knee Documentation Committee subjective knee evaluation (IKDC) scores were collected at 6-month and 12-month follow-ups, and associations between IFP volume and patient-reported outcomes were determined.

Results
The IFP volume in the ACLR limb increased from 6 months (19.67 ± 6.30 cm3) to 12 months (21.26 ± 6.91 cm3) post-ACLR. Greater increases of IFP volume between 6 and 12 months were significantly associated with better 6-month IKDC scores (r = .44, P = .03). The IFP volume was greater in the uninjured limb (22.71 ± 7.87 cm3) than in the ACLR limb (20.75 ± 9.03 cm3) 12 months post-ACLR.

Conclusions
The IFP volume increased between 6 and 12 months post-ACLR; however, the IFP volume of the ACLR limb remained smaller than that of the uninjured limb at 12 months. In addition, those with better knee function 6 months post-ACLR demonstrated greater increases in IFP volume between 6 and 12 months post-ACLR. This suggests that greater IFP volumes may play a role in long-term joint health after ACLR.

Published: March 2021

This study used remote sensing and Geo-graphical Information System (GIS) to assess the status of Awoja watersheds in Ngora district of Eastern Uganda. Landsat ETM Images covering the whole of Ngora district and part of Lake Kyoga of two time periods was carried out in the period April to July 2015. This wasacquired using USGS Earth Explorer. The images were processed and enhanced with ERDAS 2014 software to aid information extraction and analysis. Land cover change analysis was performed using ENVI 5.3 software. Supervised classification method with maximum likelihood algorithm was performed to obtain land use/ cover types. Five land use/cover types were identified: open water, wetland, tree cover, agriculture and built up area. The findings indicate a fivefold increase in built up area by 154.27km2 (i.e. 375%) and open water increased by 8.7 km2 (i.e. 55.33%). Wetland, tree cover and agriculture reduced in area by -1.0km2 (i.e. 5.1%), - 48.07 km2 (i.e. 34.46%) and -114.0km2 (i.e. 51.05%), respectively. These changes mainly resulted from deforestation, wetland encroachment, poor attitude and over population. Unless, appropriate watershed restoration strategies are designed through afforestation, law enforcement on culprits, continuous sensitisation of the watershed community on the causes of degradation, the over 1,700,000 individuals whose livelihoods depend on Awojawill continue to suffer the effects of degradation. There is need to advocate for non-consumptive projects as alternative sources of income. Keywords: Remote sensing, GIS, Watersheds.

Published: March 2021

Zooplankton community constitutes one of the keystone organisms that are crucial in understanding aquatic ecosystem responses to environmental distresses. The objective of this study was to contribute to the understanding of zooplankton ecological conservation status and assessment of potential impacts of the proposed Hydropower plant on the zooplankton community in River Aswa, Nwoya District, in Uganda. Baseline information on aquatic micro-invertebrate diversity, abundance and distribution along the affected river section was generated. Two copepods and four species of rotifers were recorded. The Intake site had the highest diversity (six species) while Powerhouse hadfour species. Of the species encountered, Keratella tropica registered the highest abundance—1,025 and 732 individuals m-2 at the Powerhouse and Intake sites, respectively. Total zooplankton densities were comparable with Intake (2,773 individuals m-2) and Powerhouse (2,311 individuals m-2). The zooplankton taxa do not appear in the IUCN Red List in the Catalogue of Life. Therefore, the proposed construction of a hydropower plant may not pose zooplankton conservation problems.
