    The paper analyses traditional quality control methods for business processes and their efficiency in respect to semi-structured process. We update a classical methodology to handle semi-structured processes: improve its execution and operational efficiency in a company. We propose Some new methods: under the Define step – a new method for describing business processes with the help of semantic maps; under the Measure step – a new method for the automated detection of non-random deviations (bottlenecks, errors); under the Analyse step – a new method for automated experts search to identify the root causes of business process problems based on an analysis of the information field

    In modern conditions of falling business activity of enterprises and falling incomes of the population, the growing trend of electricity shortages persists. This need may be aggravated by the high level of deterioration of equipment at Russian thermal power plants. All world practice shifts the guidelines for expanding electricity production towards the creation of a market for pre-fabricated renewable energy sources. In the article, the authors focused on justifying the need for the massive construction of wind power plants as an alternative source of energy. Today, «traditional» energy sources cannot meet the growing demand in remote areas of the Tyumen region with districts in the context of the spread of modern information technologies and the process of digitalization of public services. The current situation also imposes significant restrictions on the intensity of the development of the process of educational technologies in remote settlements. In this connection, the authors of the article decided to conduct an analytical study to substantiate the ways of territorial development through the launch of projects for the construction of compact wind power plants as an alternative source of energy in providing resources to remote settlements

    BackgroundOlfactory groove meningioma (OGM) is frequently associated with neuropsychological and behavioral impairments. However, there is currently a lack of evidence on the pathobiology of these functional alterations. In this study, our objective was to evaluate functional connectivity disturbances in patients with OGMs compared to healthy controls.MethodsNineteen patients with OGMs and twenty healthy controls were enrolled. The seed-based functional connectivity analysis used the main hubs of the default mode network (DMN), salience network (SN), and fronto-parietal network (FPN) as seeds. Region-of-interest (ROI)-to-voxel second-level analysis was conducted, revealing the most significant clusters of differences in brain functional connectivity between the groups.ResultsPatients with OGMs demonstrated significant alterations in resting-state functional connectivity within the DMN, SN, and FPN compared to controls. Specifically, within the DMN, we identified abnormal connectivity patterns involving the medial prefrontal cortex bilaterally, posterior cingulate cortex bilaterally, and right posterolateral cortex. In the SN, we observed enhanced functional connectivity between the anterior cingulate cortex bilaterally and left frontal, temporal, and insular regions. Additionally, the FPN exhibited disrupted connectivity of the right posterior parietal cortex with other brain areas. Notably, some connectivity changes were related to perilesional edema volume, visual acuity, and clinical metrics (KPS and MoCA scores).ConclusionWe revealed significant alterations in DMN, SN, and FPN function in patients with olfactory groove meningiomas compared with controls. These changes were associated with clinical variables and lesion characteristics. To our knowledge, this is the first report on rs-fMRI alterations in patients with olfactory groove meningiomas

    Представлена сравнительная характеристика содержания биогенных элементов и органического вещества, а также количественных показателей фитопланктона Пензенского (Сурского) водохранилища в периоды 1984–1992 и 2016–2019 гг. В настоящее время содержание фосфатов увеличилось в 3 раза, концентрация минерального азота осталась на прежнем уровне. Сезонная динамика фосфора и минерального азота различалась: максимальные концентрации фосфатов наблюдали летом и осенью, а азота – в паводковый период. Доминирующим источником генезиса фосфора сейчас являются, вероятно, внутриводоемные процессы. Преобладающей формой минерального азота в 2016–2019 гг. стали нитраты, весенний максимум которых свидетельствует о преимущественном поступлении с паводковым стоком. Соотношение минеральных форм N и Р указывает на то, что фосфор не лимитирует развитие водорослей. В отдельные периоды (лето 2017–2018 гг.) наблюдали достоверную отрицательную связь между величиной биомассы водорослей и содержанием общего железа в воде (r = -0,81, р = 0,016). «Цветения» воды в течение последних лет не отмечалось. В 2019 г. численность Cyanoprocaryota возросла, но биомасса их на отдельных участках не превышала 2,18–2,42 мг/дм3. В доминирующем комплексе цианопрокариот в 2019 г. практически отсутствовал Microcystis aeruginosa (Kütz.), но появился Planktothrix agardhii (Gom.) Anagn. et Kom., устойчивый к малой освещенности и низкому соотношению азота и фосфора. Доля легкоокисляемого органического вещества в общем органическом веществе как в конце XX в., так и в последнее время характеризует водохранилище как стабильно эвтрофное, тем не менее количественные характеристики фитопланктона в последние годы свидетельствуют об уменьшении трофностиThe present study provides comparative characterization of the contents of nutrients and organic matter and quantitative parameters of phytoplankton of the Sura (Penza) reservoir during 1984–1992 and 2016–2019. At present, the content of phosphates has increased by 3 times while the concentration of mineral nitrogen has remained unchanged. The seasonal dynamics of phosphorus and mineral nitrogen are different: the maximum phosphate concentrations are observed in summer and autumn, but nitrogen is the highest during the flood period. At the present time, phosphorus is mainly generated in intra-reservoir processes. Nitrates were the predominant form of mineral nitrogen in 2016–2019, and their spring maximum suggests predominant intake with the flood flow. The ratio of the mineral forms of nitrogen and phosphorus indicates that, at the present time, phosphorus is not the element that limits the development of algae. In certain periods (summer 2017–2018), a significant negative relationship was observed between the algal biomass and the total iron content in water (r = -0.81, p = 0.016). No Cyanoprocaryota “blooms” have been observed in recent years. In 2019, the abundance of Cyanoprocaryota increased, but in some regions, biomass was no more than 2.18–2.42 mg/dm3. In 2019, the dominant Cyanoprocaryota group did not contain Microcystis aeruginosa (Kütz.), but a new species was identified – Planktothrix agardhii (Gom.) Anagn. et Kom., which is resistant to low light and the low nitrogen to phosphorus ratio. The proportion of readily oxidized organic matter in the total organic matter, both at the end of the 20th century and recently, characterizes the reservoir as stably eutrophic, although the quantitative characteristics of phytoplankton in recent years indicate declining trophic statu

    В статье представлены данные, полученные при изучении бактерий, выделенных из ризосферы орхидеи Epipactis atrorubens (Hoffm.) Besser. Проведен сравнительный анализ некоторых морфологических, физиологических и биохимических характеристик ризобактерий растений, произрастающих в двух биотопах на серпентинитовых породах: в естественном лесном фитоценозе (фоновый участок) и на отвале после добычи асбеста (Свердловская область, Средний Урал). Оценка ростстимулирующей (PGP) активности выделенных штаммов не показала достоверных различий между исследованными участками по способности ризобактерий к синтезу индолил‑3-уксусной кислоты (ИУК) и солюбилизации фосфатов. Однако доля изолятов, способных к азотфиксации, была выше в ризосфере E. atrorubens, произрастающего на отвале, по сравнению с фоновым местообитанием. Устойчивость изолятов к тяжелым металлам оценивали по максимальной концентрации металла (400, 600 и 1000 мг/л соответственно для Ni, Cu и Zn), при которой отмечался рост бактерий. Показано, что ризобактерии с отвала оказались более устойчивыми к повышенным концентрациям металлов по сравнению с естественным лесным фитоценозом. На основе молекулярно-генетического анализа изолятов с наиболее выраженной PGP‑активностью (ИУК >1,0 мг/л; PO4 3- >50,0 мг/л) обнаружено сходство между изученными местообитаниями по родовой принадлежности ризобактерий E. atrorubens: выделенные штаммы принадлежали преимущественно к родам Buttiauxella и Pseudomonas. В модельных экспериментах протестирована ростстимулирующая способность четырех отобранных штаммов на семенах циннии. Инокуляция семян Pseudomonas sp. и Buttiauxella sp. не оказывала значимого влияния на их всхожесть, однако Buttiauxella sp. способствовала увеличению длины проростков в сравнении с контролем (в среднем на 25 %). Сделано предположение, что отобранные изоляты ризобактерий E. atrorubens, благодаря их ростстимулирующей активности и металлоустойчивости, могут способствовать натурализации орхидеи на техногенно нарушенной территорииThe article presents data obtained in the study of bacteria isolated from the rhizosphere of the orchid Epipactis atrorubens (Hoffm.) Besser. Analysis was carried out to compare some morphological, physiological, and biochemical characteristics of plant rhizobacteria growing on serpentine rocks in two biotopes: in the natural forest community (control habitat) and on the asbestos mine dump (the Sverdlovsk region, Middle Urals). An assessment of the plant growth promoting (PGP) activity of the isolated strains did not show significant differences in the ability of rhizobacteria to synthesize indol‑3-acetic acid (IAA) and solubilize phosphates between the study sites. However, the proportion of isolates capable of nitrogen fixation was higher in the rhizosphere of E. atrorubens growing on the dump compared to the control habitat. The tolerance of isolates to heavy metals was assessed by the maximum metal concentration (400, 600, and 1000 mg/L, respectively, for Ni, Cu, and Zn) at which bacterial growth was observed. Rhizobacteria from the dump were found to be more resistant to elevated concentrations of metals compared to their counterparts from the natural forest community. The molecular genetic analysis of isolates with the highest PGP‑activity (IAA >1.0 mg/L; PO4 3- >50.0 mg/L) revealed that most of the E. atrorubens rhizobacteria in both habitats belonged to the genera Buttiauxella and Pseudomonas. In model experiments, the PGP ability of four selected strains was tested on zinnia seeds. Seed inoculation with Pseudomonas sp. and Buttiauxella sp. did not have any significant effect on their germination; however, Buttiauxella sp. contributed to the increase in the length of seedlings compared with the control (by 25 %, on average). It has been suggested that the selected isolates of E. atrorubens rhizobacteria, due to their growth promoting activity and metal tolerance, can facilitate naturalization of the orchid in an industrially disturbed are

However, previous findings have been inconsistent, partially due to low statistical power and the heterogeneity of depression. In the largest multi-site study to date, we examined WM anisotropy and diffusivity in 1305 MDD patients and 1602 healthy controls (age range 12-88 years) from 20 samples worldwide, which included both adults and adolescents, within the MDD Working Group of the Enhancing Neuroimaging Genetics through Meta-Analysis (ENIGMA) consortium. Processing of diffusion tensor imaging (DTI) data and statistical analyses were harmonized across sites and effects were meta-analyzed across studies. We observed subtle, but widespread, lower fractional anisotropy (FA) in adult MDD patients compared with controls in 16 out of 25 WM tracts of interest (Cohen's d between 0.12 and 0.26). The largest differences were observed in the corpus callosum and corona radiata. Widespread higher radial diffusivity (RD) was also observed (all Cohen's d between 0.12 and 0.18). Findings appeared to be driven by patients with recurrent MDD and an adult age of onset of depression. White matter microstructural differences in a smaller sample of adolescent MDD patients and controls did not survive correction for multiple testing. In this coordinated and harmonized multisite DTI study, we showed subtle, but widespread differences in WM microstructure in adult MDD, which may suggest structural disconnectivity in MDD
