A Methodology for Modelling of Steady State Flow in Pelton Turbine Injectors
Authors: Bajracharya Tri Ratna , Shrestha Rajendra , Timilsina Ashesh Babu
Published: February 2020

Pelton turbine is a high head-impulse type turbine. The high-speed jet strikes the symmetrical semi ellipsoidal buckets, thus transferring the momentum within short period of time, impulse. The conversion of potential energy of water to kinetic energy in the form of jet is done by a nozzle with internally fitted spear or needle, the assembly in known as injector. The jet quality includes but is not limited to jet velocity, velocity distribution ‘velocity profile’, core location etc. In this study, the modeling of flow in Pelton turbine injector is done by commercial Computational Fluid Dynamics (CFD) solver on a three-dimensional flow domain. The results obtained from CFD modelling are then compared against the experimental observations and previously published literatures. The jet streamline, jet velocity profile and jet core location are then studied. As observed experimentally, the mean jet diameter reduces as the nozzle opening decreases. In addition, like the experimental observations, the jet first contracts and then expands. The diameter of the contraction is then normalized with nozzle exit diameter and is plotted for both experimental observations as well as the results of the numerical simulation. The maximum error between experimental and numerical analysis of jet contraction is 20%. The jet core is located at region axially ahead of needle tip.

Panchase Protected Forest (PPF), situated at the junction of three districts Kaski, Syangjaand Parbat with an elevation range of 900-2517m representing mid hills of Nepal. This study was carried out with an aim of documenting the flowering plant diversity of the Panchase Protected Forest, Kaski district, comprising three VDCs, Bhadaure Tamage, Chapakot and Pumdi Bhumdi. General survey, covering all seasons was organized (from June 2014 to May2015) for collecting the plant species. Published literatures and herbarium specimens were also consulted for documenting the species. Identification of the collected specimens was made through consulting relevant literatures, herbarium specimens and expert consultation. A total of 613 species belonging to 393 genera and 111 families have been documented from this area. The dominant family was Orchidaceae (49 genera and 125 species) followed by Poaceae (25 spp.), Asteraceae (25 spp.) and others. Six endemic plants, Begonia flagellaris (Begoniaceae), Eria pokharensis, Gastrochilus nepalensis, Oberonia nepalensis, Odontochilusnandae and Panisea panchaseensis (Orchidaceae) were also reported. Similarly, presentresearch revealed two taxa as new record for flora of Nepal, Dischidia bengalensis Colebr. (Apocynaceae) and Phreatia elegans Lindl. (Orchidaceae). The present findings suggest that PPF is one of the hotspot for floral diversity representing mid hills of Nepal and this pristine habitat for orchid should be developed as ‘Orchid Sanctuary’.

Published: February 2020

Understanding people’s knowledge and their dependency on wetland forms the basis of conserving them. The paper assessed the status of wetland in Rampur and local peoples’ dependency on it, conducted in the year of 2013. Study revealed that majority of respondents noticed change in wetland in past years and in their priority, drying ranked first followed by decrease in acreage, and biodiversity loss. It was found that factors responsible for these changes were drought, encroachment, flooding, erosion and succession by invasive weed species. Study found that local peoples have several impacts on wetland which were conversion for agriculture, discharge of pollutants, overexploitation of aquatic resources, overgrazing conversion for residential development, and conversion for aquaculture. However, Negative impacts of wetland were flooding, foul smell, incidence of insect pest/disease, coldness in winter, and bank cutting. It was found that people dependent on wetland for farming, fodder collection, fuel wood collection, medicinal plants, religious purpose, fishery, livestock grazing, wild edible plants, irrigation, commercial fishery and recreation. Study showed that local peoples have knowledge about several aspects of wetland and they are dependent for their livelihood. Therefore, in order to protect wetland from degradation, conservation and management activities need to be implemented properly with the involvement of local peoples.

Published: February 2020

Different parts of plant have been used since many decades by humans for catching fishes. In this investigation, ‘ketuke ‘leaf effect was observed on behavioral change and histological alterations in the kidney of Clarias batrachus. Few fishes were kept as control i.e. not exposed to plant piscicide. The other fishes were exposed to 3gm per 30 liters of water for 24 and 48 hrs. In exposed fish’s restlessness, vigorous movement, excessive secretion of slime and loss of appetite was seen. Histologically, glomerular contraction, clumping of melanomacrophages, degeneration of epithelial tissue along with the degeneration of renal tubules and others were seen. Increase in the Bowman’s space was one of the noticeable changes. Extract accumulation was seen in the tissues. Exposure to sub lethal concentrations of Ketuke (Agave americana), caused duration dependent histopathological alterations in the kidney of Clarias batrachus which is discussed in the paper.

Natural Disasters Versus Anthropogenic Activities in Nepal Himalayas: Case Study from Ghatte Khola , Myagdi
Authors: Gurung Narayan
Published: February 2020

In the Himalayas, geo-hazards are natural events occurring more or less frequently and of a greater or lesser magnitude. But when natural hazards affect people and property, then it becomes disasters. It’s believed that natural disasters as such do not exist. Everything is just natural hazard and anything can turn into disasters due to anthropogenic activities. Thus, natural phenomenons are hazards while disasters are anthropogenic. In this regard, a case study was being conducted in the Ghatte Khola (Dana) of Myagdi District in Western Central Nepal, where in a context of growing population and haphazard construction of infrastructures, natural dynamics have turned into disasters. The Ghatte Khola is an intermittent, right bank tributary of the Kali Gandaki, which behaves occasionally as a debris flow, in relation with slope instabilities that affect its upstream catchment. The debris flows are usually triggered during heavy cloudbursts, and can cause damages and losses downstream, along the wide alluvial fan built at the tributary junction and upon which Dana village (Myagdi District) is settled. Inhabitants are aware of this ephemeral, yet threatening behaviour of the stream that may also affect the Kali Gandaki valley upstream from the confluence (Lat. 28°32'22" N and Long. 83°39'03" E). The Ghatte Khola is often affected by debris flows bringing sediment fluxes that are eroding its banks every year. A motor bridge was being built over Ghatte Khola near the confluence with Kali Gandaki and further, a large electric power station is being built on the right bank of Ghatte Khola. Sadly, the bridge was washed away by the flash flood in Ghattekhola on 25th May 2019. This study was focused on vulnerability of these man made infrastructures and their future on Ghatte Khola debris flow dynamics, with hazard that might occasionally transform into disaster.

The article presents data on the development in the lumen of the pancreatic duct of condensed protein masses in people who died from the development of severe acute pancreatitis. 10 pancreas (areas of the head, body and tail, ductal system of the pancreas) of people who died of acute pancreatitis were subjected to histological examination. The material was fixed in 10% formalin solution, carried out in alcohols of increasing strength and enclosed in celloidin. The sections were stained with hematoxylin and eosin. A histological examination revealed that the condensed masses were represented by heterogeneous protein formations, cells of desquamated ductal epithelium, blood elements, fibrin threads. They completely filled the lumen of the pancreatic ducts and stopped the movement of pancreatic secretion. The data on the treatment of severe pancreatitis in experimental studies using the method of bougie and washing the pancreatic ducts with a novocaine-contrical mixture are presented. Two methods are proposed for restoring the permeability of the pancreatic duct in pancreatic necrosis in humans. Possible ways of the formation of fistulas and cysts are suggested, as a complication in the severe course of acute pancreatitis.
Structural and hemodynamic changes in the carotid arteries in young healthy individuals with concentric remodeling of the left ventricle and with normal heart geometry
Authors: Sheremta B.V. , Osovskaya N.Yu.
Published: February 2020

Remodeling of the heart and blood vessels is a complex multifactorial process that determines the prognosis of a patient with different cardiovascular pathologies. The aim of this work is to study in a comparative aspect the features of the hemodynamics of the carotid arteries as marker vessels of the elastic type and the daily blood pressure profile in young healthy individuals with concentric remodeling of the left ventricle and with normal heart geometry. The study involved practically healthy individuals from 18 to 42, aged 25.3±0.6 years, 56 (73.7%) men and 20 (26.36%) women. All study participants were divided into two equal groups depending on the value of the relative wall thickness of the left ventricle (RTW) for 38 people: for RTW>0.42 (concentric remodeling of the left ventricle) and for RTW≤0.42 (normal geometry of the left ventricle). The following research methods were used: echocardiography, 24-hour blood pressure monitoring, duplex scanning of the neck vessels. Statistical analysis of the study results was calculated using the methods of variational statistics using the StatSoft complex “Statistica” v.12. Although the average daily values of blood pressure and the degree of its nightly decline in both groups did not differ significantly, the speed of the morning rise and the variability of systolic pressure were significantly higher in patients with concentric remodeling than without it. That is, even in the absence of symptoms of cardiovascular disease and a history of a rise in blood pressure, the hemodynamic factor of a fast morning increase in blood pressure can take part in the formation of changes in the geometry of the heart in practically healthy young people. Changes in the speed-time parameters of blood flow in the common carotid arteries in the absence of wall thickening (intima-media complex) and a parallel increase in the lumen of the internal jugular veins found in the study indicate structural and hemodynamic vascular remodeling associated with concentric remodeling of the left ventricle in young, practically healthy persons.
The possibilities of pharmacological correction of the disturbance of carbohydrate metabolism in brain rates with traumatic brain injury
Authors: Semenenko S.I.
Published: February 2020

The development and introduction into practice of emergency neurology of new drugs capable of influencing the secondary damage of neurons in patients with traumatic brain injury (TBI) has significantly affected the recovery of such patients. The aim of the study was to evaluate the magnitude of the cerebroprotective effect of amantadine sulfate on the index of impaired carbohydrate metabolism of the brain against the background of experimental TBI. The experimental TBI model of severe severity was caused by the action of a carbon dioxide flow under pressure created using a gas balloon pneumatic gun. The therapeutic effect of amantadine sulfate on model TBI was evaluated using a dose of 10 mg/kg. The pseudoperated animals and control group received 0.9% NaCl solution at a dose of 2 ml/kg i/v. The obtained results were processed by the method of variational statistics using Student's t-test, changes of indicators were considered probable at p≤0.05. In the course of the experiment, it was found that the treatment of rats with model TBI with 0.9% NaCl solution did not significantly contribute to the restoration of impaired energy metabolism (p<0.05) and did not reduce the manifestation of metabolic acidosis in the damaged brain (p<0.05). The use of amantadine sulfate in TBI rats significantly better corrects carbohydrate metabolism disorders than 0.9% NaCl solution and contributes to the reduction of metabolic acidosis in the damaged brain (p<0.05).
Bowel decompression in the treatment of patients with acute colonic obstruction
Authors: Nepomniashchyi V.V.
Published: February 2020

According to literature data acute intestinal obstruction is characterized by a great number of neglected forms comprising 5–70% cases with the given pathology. A number of radiological signs in the way of Kloiber’s bowls and intestinal arches simply confirm this and testify of colon motor activity decompensation. To date there are no objective diagnostic criteria providing indications to intestinal decompression before the operation. Intestinal intubation, its types and indications to its fulfilment are based only on the experience and intuition of the operating surgeon. Aim — to define clinical efficiency of the intestinal wall impaired contractility diagnostics method in the treatment of patients with acute colonic obstruction. Medical histories analysis of 166 patients with obstructive intestinal obstruction was carried out. Assessment of intestinal motor activity compensation was carried out with the help of echographic criteria — the number of enlarged small bowel loops, intestinal lumen width, wall thickness, distance between Kerckring folds, number of peristaltic movements per minute. According to the suggested method 3 groups of patients were distinguished — with compensated motor activity (32 (19%) patients), with sub-compensated motor activity (61 (36.5%) patients) and with intestinal decompensated motor activity (73 (44.4%) patients). Wherein the greater number of patients with obstructive ileus (135 (81%) patients) got into the hospital with sub- and decompensated intestinal motor function. In the group of patients with compensated muscular tone intestinal decompression was not carried out, in the second group with sub-compensated intestinal tone decompression was carried out simultaneously in 13 (7.8%) patients, and in 9 (5.4%) a nasojunal probe was installed for 2–3 days, in the third group intestinal intubation was done in 63 (38%) patients. Post-operative mortality was 3.2%. Thus, echographic criteria allow establishing the degree of intestinal impaired motor function before the operation in patients with acute intestinal obstruction which decompression depends upon its state.
Constitutional features of the occurrence and course of psoriasis (analysis of scientific literature)
Authors: Al-Qaraleh Obadeh Bassam Abdel-Rahman
Published: February 2020

The purpose of the work is to analyze the scientific literature on the constitutional features of the occurrence and course of psoriasis. The analysis of modern scientific literature in the scientific databases PubMed, eLIBRARY.RU and Web of Science was carried out. A review of the literature indicates the current state of the problem of such a disease as psoriasis, which is not only a skin lesion but also a serious socio-psychological problem. Given its chronic nature, lack of etiopathogenetic treatment, and knowing the trigger factors in the right way, it would be a good idea to look for early predisposition for the disease and to form risk groups for such individuals. Ideal in terms of efficiency and cheapness, given the results of the above studies, could be anthropological studies. The study of the constitutional features of the occurrence and course of psoriasis for the population of Ukraine is thus a priority and topical area of research.

OBJECTIVE

Patients with metastatic thyroid cancer have prolonged survival compared to those with other primary tumors. The spine is the most common site of osseous involvement in cases of metastatic thyroid cancer. As a result, obtaining durable local control (LC) in the spine is crucial. This study aimed to evaluate the efficacy of spine stereotactic radiosurgery (SSRS) in patients with metastatic thyroid cancer.

METHODS

Information on patients with metastatic thyroid cancer treated with SSRS for spinal metastases was retrospectively evaluated. SSRS was delivered with a simultaneous integrated boost technique using single- or multiple-fraction treatments. LC, defined as stable or reduced disease volume, was evaluated by examining posttreatment MRI, CT, and PET studies.

RESULTS

A total of 133 lesions were treated in 67 patients. The median follow-up duration was 31 months. Dose regimens for SSRS included 18 Gy in 1 fraction, 27 Gy in 3 fractions, and 30 Gy in 5 fractions. The histology distribution was 36% follicular, 33% papillary, 15% medullary, 13% Hurthle cell, and 3% anaplastic. The 1-, 2-, and 5-year LC rates were 96%, 89%, and 82%, respectively. The median overall survival (OS) was 43 months, with 1-, 2-, and 5-year survival rates of 86%, 74%, and 44%, respectively. There was no correlation between the absolute biological equivalent dose (BED) and OS or LC. Patients with effective LC had a trend toward improved OS when compared to patients who had local failure: 68 versus 28 months (p = 0.07). In terms of toxicity, 5 vertebral compression fractures (2.8%) occurred, and only 1 case (0.6%) of greater than or equal to grade 3 toxicity (esophageal stenosis) was reported.

CONCLUSIONS

SSRS is a safe and effective treatment option with excellent LC and minimal toxicity for patients with metastatic thyroid cancer. No association with increased radiation dose or BED was found, suggesting that such patients can be effectively treated with reduced dose regimens.
What is the incidence of cauda equina syndrome? A systematic review
Authors: Hoeritzauer Ingrid , Wood Matthew , Copley Phillip C. , Demetriades Andreas K. , Woodfield Julie
Published: February 2020

OBJECTIVE

Cauda equina syndrome (CES) is a surgical emergency requiring timely operative intervention to prevent symptom progression. Accurately establishing the incidence of CES is required to inform healthcare service design and delivery, including out-of-hours imaging arrangements.

METHODS

A systematic literature search of MEDLINE, EMBASE, and Scopus was undertaken to identify original studies stating the incidence of CES, and the estimates were combined in a meta-analysis as described in the protocol registered with PROSPERO (registration no. CRD42017065865) and reported using the PRISMA guidelines.

RESULTS

A total of 1281 studies were identified, and 26 studies were included in the review. Data about CES incidence were available from 3 different populations: asymptomatic community populations, patients with nontraumatic low-back pain, and patients presenting as an emergency with suspected CES. The incidence of CES was 0.3–0.5 per 100,000 per year in 2 asymptomatic community populations, 0.6 per 100,000 per year in an asymptomatic adult population, and 7 per 100,000 per year in an asymptomatic working-age population. CES occurred in 0.08% of those with low-back pain presenting to primary care in 1 study, and a combined estimate of 0.27% was calculated for 4 studies of those with low-back pain presenting to secondary care. Across 18 studies of adults with suspected CES, 19% had radiological and clinical CES. Difficulties in comparison between studies resulted from the heterogeneous definitions of CES and lack of separation of more advanced CES with retention, which is unlikely to be reversible. In the studies of patients with suspected CES, the small sample size, the high number of single-center studies (18/18), the high number of studies from the United Kingdom (17/18), the retrospective nature of the studies, and the high number of abstracts rather than full texts (9/18) reduced the quality of the data.

CONCLUSIONS

From current studies, it appears that CES occurs infrequently in asymptomatic community populations and in only 19% of those presenting with symptoms. Determining accurate incidence figures and designing a bespoke service for investigation of patients with suspected CES would require a consensus clinical and radiological definition of CES and international multisite studies of patient pathways of investigation and management.

Published: February 2020

BACKGROUND:

Radical cystectomy (RC) often requires a prolonged course of opioid medications for postoperative pain management. We implemented a Reduced Opioid Utilization (ROU) protocol to decrease exposure to opioid medications.

OBJECTIVE:

To determine the impact of the ROU protocol on opioid exposure, pain control, inpatient recovery, and complication rates among patients who underwent RC.

METHODS:

The ROU protocol includes standardized recovery pathways, a multimodal opioid-sparing pain regimen, and improved patient and provider education regarding non-opioid medications. Opioid exposure was calculated as morphine equivalent dose (MED), and was compared between RC patients following the ROU protocol and patients who previously followed our traditional pathway. Opioid-related adverse drug events (ORADEs), pain scores, length of stay, and 90-day complications, readmission, and mortality were also compared between cohorts.

RESULTS:

104 patients underwent RC, 54 (52%) of whom followed the ROU protocol. ROU patients experienced a statistically significant decrease in opioid exposure in the post-anesthesia care unit ( p = 0.003) and during their postoperative recovery (85.7±21.0 MED vs 352.6±34.4 MED, p < 0.001). The ROU protocol was associated with a statistically significant decrease in ORADEs after surgery. There was no significant difference in average pain scores, length of stay, readmissions, or 90-day complication or mortality rates.

CONCLUSIONS:

The ROU protocol decreased opioid use by 77% without compromising pain control or increasing the rate of complications. This study demonstrates the efficacy of non-opioid medications in controlling postoperative pain, and highlights the role providers can play to decrease patient exposure to opioids after RC surgery.
The state of the late Protestant denominations
Authors: Yarotskiy Petro
Published: February 2020

Late Protestantism - Baptists, Pentecostals, Adventists, and Jehovah's Witnesses have existed in Ukraine for over a hundred years. Under Soviet rule, these denominations were under constant administrative pressure, subject to party-ideological criticism, atheistic propaganda. The Pentecostals were virtually banned and non-registrable, since they were forcibly annexed by evangelical Baptist Christians after the August 1945 state agreement initiated by the Moscow authorities. From the very beginning of the establishment of Soviet power in Western Ukraine (1939), Jehovah's Witnesses were declared an "anti-Soviet sect" and were therefore banned. In March 1951, an act of genocide was committed against Jehovah's Witnesses: according to the "Memorandum Note of the USSR Ministry of State Security", approved by J. Stalin's personal signature, all Jehovah's Witnesses, together with their families (7650 persons), were sent from Ukraine to eternal settlement in Siberia. without the right of return to Ukraine, and their homes and property were confiscated by the state.

All these changes are taking place against the background of global transformations in the modern world, which is becoming increasingly open to interactions and interactions between its various elements, pluralistic and multicultural, in which different religious traditions freely coexist. At the same time, it shows discrimination against certain groups of people called minorities. Minorities are increasingly experiencing political, cultural, economic and physical oppression, and even genocide.

Published: February 2020

The peat waters area such as swamps, lakes and rivers, are essential habitat for many fish which consumed by Arut-Kumai residents who live in the city of Pangkalan Bun. Fish species diversity and its potential are not yet widely known, therefore it needs to be revealed. The research aims to reveal fish biodiversity and its potential in the peat waters of the Arut Lamandau-Kumai River Basin, west Kotawaringin Regency. The study was conducted in October-December 2017. Fish samples were captured by using cast net, gill nets, hooks and rods, fish traps. During the study period, a number of 95 fish species belonging to 50 genera, 23 families dan 6 orders were collected. The most common family was Cyprinidae, followed by Siluridae, Osphronemidae, Chanidae dan Bagridae. Dominant genera were Osteochilus and Rasbora, Kyrptopterus, Betta Channa. As many as 70 species as consumption fish, 53 species as ornamental fish, while 56 species have the potential as aquaculture fish. The fish habitat in the Arut-Lamandau river is a peat area that stretches in the buffer zone of the eastern part of the Lamandau River Wildlife Reserve, that has been transformed into an oil palm plantation. In addition, logging activity is occurred mainly in peat ecosystem areas in production forest areas. These activities are thought to cause a reduction fish population in Arut-Kumai peat waters.

Banyak informasi yang menyebutkan bahwa Islam masuk ke Indonesia melalui jalur tarekat. Ajaran-ajaran tarekat yang berakar dari tradisi tasawuf ini kemudian menyebar, seperti benih yang tumbuh di lahan yang subur. Ini yang menyebabkan bahwa kajian dan pengamal tarekat di Indonesia tidak pernah sepi dari peminatnya. Di Indonesia, sebelum abad ke 18 dan 19, tarekat tumbuh dalam lingkungan istana. Namun setelah penjajahan kolonial Belanja berhasil menancapkan kuku kekuasaannya di Indonesia, tarekat bergeser ke pedalaman, dipelajari dan dipraktekkan di lingkungan pesantren. Pesantren memang memiliki akar sejarah yang panjang di Indonesia, khususnya dalam hal penyebaran agama Islam. Di samping itu, pesantren juga punya peran signifikan dalam konteks pendidikan keagamaan Islam. Beragaman khazanah intelektual Islam seperti aqidah, fiqh, tafsir, hadis, tasawuf dan lain sebagainya diajarkan dalam pesantren. Di samping itu, tarekat juga menjadi magnet lain bagi pertumbuhan pesantren di Nusantara. Tarekat memang tidak semata disuguhkan dalam konteks kajian ilmiah. Ia juga disuguhkan menjadi praktek yang hidup di tengah-tengah masyarakat untuk membimbing umat Islam berjalan untuk berjumpa dengan Allah dan memperbaiki akhlak melalui berbagai latihan tarekat. Pengajaran tarekat membutuhkan kedekatan antara murid dengan seorang mursyid. Dalam konteks itulah, pesantren menjadi lahan yang cocok bagi pengajaran tarekat, khususnya di Indonesia.Kata Kunci: Tasawuf, Tarekat, Mursyid, Kiai dan Pesantren

The technological equipment under consideration relates to air-cushioned out-door vehicles operating from the workshop pneumatic network. Their designs are based on the modular principle. A typical design of such equipment equipped with inflatable balloon fences is presented. The effectiveness of their use in aircraft construction is shown. When performing interoperational movements, they provide savings in production space due to the compact placement of aircraft in assembly shops. When performing mounting and docking operations, the proposed equipment does not require accurate combination of mating units and simplifies the process of docking heavy units. The equipment also allows for cyclic ground tests of a rotary wing of an aircraft with loads close to flight. This eliminates possible emergency situations during flight tests and ensures the safety of expensive products. When performing loading and unloading operations, the use of air cushions allows to reduce the weight of loading equipment, as well as reduce the time and cost of these operations. Most researchers consider the flow to be viscous and laminar due to small flow gaps be-tween the balloon guard and the floor supporting surface. A new approach is pro-posed here. It is based on a turbulent regime of outflow from an air cushion. This is confirmed by replacing the real air path with an equivalent circular section. As a result, the configuration of the outlet channel is transformed into a short confuser diffuser nozzle with a small length along the flow. And such resistances are considered turbulent. As the first turbulent throttle acts as an air flow regulator at the en-trance to the support. Proceeding from this, calculation methods are proposed that allow one to determine expendable, energy, and specific indicators of both individual modules on air cushions and systems based on them. The information necessary for the designer is given to solve current problems in aircraft construction and other are-as of technology.

The existing tools and models for managing stakeholders of the project are analyzed. It is known that effective interaction with stakeholders positively affects on various aspects of project management. The article focuses on the need for stakeholder analysis as an integral part of the project. Great interest in this topic is related to the fact that the best results are shown by organizations that in the course of their work create value for all stakeholders. It is known that in the fifth edition of the PMBoK standard, stakeholder management was highlighted as a new independent branch of project management knowledge. Today, existing methods are intended for the level of contractors: project managers, management team, office professionals. But for the upper echelons of power there are no relevant management models. But this is the level of strategic decisions, on which about 50% of the success depends on.The article discusses theoretical and methodological approaches and stakeholder analysis models that allow to identify, evaluate the characteristics of the importance, strength, relevance of stakeholders and, depending on this, outline a strategy for managing interaction with them. It is concluded that existing methods, as a rule, consider the relationship between stakeholders and companies, but do not take into account the specifics of the project. Analyzed models and tools can be divided into 3 categories: quantitative, qualitative and complex. Quantitative models generate numerical data that can be converted to numbers. Qualitative models produce non-numerical data (visualization). Comprehensive - Combine several qualitative and quantitative models, or a combination of them. In addition, quantitative models are often complex tools that can only be used as part of an automated computing system.Thus, the development of effective methods for managing stakeholders in projects and programs is an urgent task.

Quaestio facti e Quaestio iuris
Authors: Ubertis Giulio
Published: February 2020

L’epistemologia giudiziaria studia i metodi e la validità della conoscenza nella ricostruzione giudiziale del fatto. Quindi, riguarda particolarmente la quaestio facti. Ma non si può ignorare l’indissolubile nesso esistente tra quest’ultima e la quaestio iuris. Anche la competenza di legittimità della Corte di cassazione può fondarsi non su una separazione tra questioni di fatto e questioni di diritto, ma sul divieto di svolgere attività probatoria o sulla limitazione, ad esempio, delle violazioni processuali che può esaminare.
