Development of public transport system as a factor in greening the urban environment
Authors: Kinsht A. , Malova E.
Published: June 2021

Public transport is not only an element of a city ensuring the territorial integrity, but also a factor that significantly affects the quality of the urban environment. Improvement of the public transport system and optimization its types make it possible to rebuild the urban space, providing territories for public, recreational and other functions of the city. The transport infrastructure in the urban environment without these functions results in negative consequences.

The aim of the work is to identify the advanced trends in the organization of the public transport system based on the experience of cities with a high level of urban comfort.

It is shown that without the interaction with external and internal components of the urban and transport systems, the infrastructure of public transport cannot be considered, since transport becomes a competitor for land resources for pedestrian, cycling infrastructure and landscaping. It is found that the optimization of the transport system must be oriented towards the accessibility of urban areas at any time, expanding pedestrian and green areas and reducing the negative impact on the urban environment.

Authors: Makhortova A. S. , Astakhova E. S.
Published: June 2021

The paper deals with the bicycle center infrastructure in a city, which becomes popular every year, but is not yet studied properly. Little attention is devoted to the spatial development for two-wheeled vehicles, so there are many problems to be discussed and solved.

The purpose of this paper is to determine the types of bicycle centers in the structure of a city, from the main and central to regional and peripheral that connect all urban areas. Moving along the bicycle paths from home to a large bicycle center and back to home, one can communicate in bicycle centers. Less functional peripheral centers provide repair services, bicycle rental and small recreation. The city of Rostov-on-Don is taken as an example.

The following parameters are determined: optimum distance between bicycle centers of different types, their functional content, bicycle center location in the city. In the future, it is possible to arrange such centers in any city due to their unification.

The model of the bicycle center network is proposed for the city of Rostov-on-Don, that are characterized by different area and multifunctional purposes for each district to attract people. The main bicycle center includes sports grounds, bicycle track, rock climbers, skate park, gyms, ski jumping hall and other sports facilities. Roof-top bike trails, amphitheater with a street stage, art spaces, go-karting can be arranged on the territory of these centers.

Authors: Gul Shabnam , Asghar Muhammad Faizan
Published: June 2021

The concept of propaganda and lobbying is not new to researchers. Historically, propaganda was used by many states to manipulate policies in their own favors and to oppose the other states. During WW1, WW2 and the Cold war, media was used as a propaganda tool to demoralize opponents. Gradually lobbying was initiated as foreign policy tools. Like Israel, Saudi Arabia and Russia was the most powerful lobbyist in the USA. Indian lobbyist started an anti-Pakistan campaign in the USA based on rivalry since the creation of Pakistan. This is true focuses on destabilization of the US-Pakistan relationship and to weaken the strong lobbyism between the US and Pakistan.

Restoration of sagittal alignment in high-grade isthmic spondylolisthesis using the reverse Bohlman technique with anterior lumbar interbody fusion using a hyperlordotic cage at L4–5: illustrative case
Authors: Ishmael Terrence , Arlet Vincent , Smith Harvey
Published: June 2021

BACKGROUND

Circumferential fusion with or without reduction is the preferred treatment for high-grade isthmic spondylolisthesis. Reduction presents significant risk of neurological injury. The authors present one case in which the “reverse Bohlman” technique was used with the addition of a hyperlordotic interbody cage at L4–5 as a means to correct sagittal malalignment while avoiding the reduction of L5 on S1.

OBSERVATIONS

The patient was a 22-year-old woman with a long-term history of lower back pain and bilateral L5 radiculopathy secondary to high-grade isthmic lumbar spondylolisthesis. She underwent anterior lumbar interbody fusion using the reverse Bohlman technique plus a hyperlordotic interbody cage at L4–5, followed by decompression and posterior spinal instrumentation and fusion from L4 to the pelvis. At 2-year follow-up, she was found to have complete resolution of symptoms with clinical and radiographic evidence of fusion. Her spinopelvic parameters had significantly improved.

LESSONS

The reverse Bohlman technique with the addition of a hyperlordotic interbody cage at L4–5 is a potential alternative treatment method to correct sagittal malalignment while avoiding possible injury to the L5 nerve roots that can be seen in the reduction of high-grade isthmic spondylolisthesis.
Trigeminal neuralgia induced by brainstem infarction treated with pontine descending tractotomy: illustrative case
Authors: Shanker Rachyl M. , Kim Miri , Verducci Chloe , Rezaii Elhaum G. , Steed Kerry , Mallik Atul K. , Anderson Douglas E.
Published: June 2021

BACKGROUND

While cases of trigeminal neuralgia induced by a brainstem infarct have been reported, the neurosurgical literature lacks clear treatment recommendations in this subpopulation.

OBSERVATIONS

The authors present the first case report of infarct-related trigeminal neuralgia treated with pontine descending tractotomy that resulted in durable pain relief after multiple failed surgical interventions, including previous microvascular decompressions and stereotactic radiosurgery. A neuronavigated pontine descending tractotomy of the spinal trigeminal tract was performed and resulted in successful pain relief for a 50-month follow-up period.

LESSONS

While many cases of ischemic brainstem lesions are caused by acute stroke, the authors assert that cerebral small vessel disease also plays a role in certain cases and that the relationship between these chronic ischemic brainstem lesions and trigeminal neuralgia is more likely to be overlooked. Furthermore, neurovascular compression may obscure the causative mechanism of infarct-related trigeminal neuralgia, leading to unsuccessful decompressive surgeries in cases in which neurovascular compression may be noncontributory to pain symptomatology. Pontine descending tractotomy may be beneficial in select patients and can be performed either alone or concurrently with microvascular decompression in cases in which the interplay between ischemic lesion and neurovascular compression in the pathophysiology of disease is not clear.

INVESTIGATION OF THE IMPACT OF THE THERMOSONICATION OPERATION ON DOOGH QUALITY AND ON THE SURVIVAL OF KLUYVEROMYCES MARXIANUS
Authors: DIDAR Zohreh
Published: June 2021

Doogh is an Iranian drink produced from yoghurt. Swelling is an undesirable change of Doogh, usually caused by Kluyveromyces marxianus. The aim of this study was the investigation of the effect of the thermosonication process on Kluyveromyces marxianus survival as well as the determination of the impact of this process on other quality parameters (viscosity and serum separation). For this reason, Kluyveromyces marxianus (about 105 cells per milliliter) inoculated into Doogh samples, thereafter samples being exposed to various thermosonication process conditions. Results showed that the thermosonication operation resulted in the reduction of the yeast population of Doogh samples. The lowest yeast population was observed in the sample subjected to acoustic density=1w/ml, T= 60°C and t=30min (1.7±0.01CFU/ml). Other operation conditions also had impact on yeast survival. Thermosonication also had significant effects on the viscosity of the Doogh samples. Serum separation of samples was also measured and observation implied changing serum separation magnitude between different samples in comparison with the control sample.

This paper considers the economic and social aspects of organizing the functioning of small forms of green tourism. The importance of developing this type of recreational business as a form of self-realization of peasant farms has been proven. The role of rural entrepreneurship as a factor of regional development has been substantiated. The paper proposes the means to improve the procedure of estimating the efficiency of small forms of entrepreneurial activity. It has been recommended to use indicators that imply an alternative form of estimating the costs of labor by the members of a peasant farm. This paper has proposed a model of a green farm as a form of alternative self-actualization of peasant farms. The positive impact on the level of income of peasants in the case of its practical implementation has been substantiated. The need has been indicated to create a system of appropriate information support for subjects of green tourism at the regional level.
TREE SPECIES CULTIVATION ON SUBSISTENCE AGRICULTURAL FIELDS IN NORTHWESTERN ETHIOPIA
Authors: MELAKU Alebel
Published: June 2021

The study was intended to identify species preferences, the relationship between livelihood status and tree planting, and the major tree growing patterns of smallholder subsistence farmers in rural Ethiopia. Data was collected through household interviews and the total enumeration of all tree species on respondents’ landholdings. A total of 23 tree species were recorded integrated within the farming landscape as boundary plantings, scattered on crop fields, around the homestead and woodlots. There was a significant difference in the mean number of trees per household across the three wealth classes. Among the three wealth classes, the medium wealth category households have a relatively higher number of tree species than rich and poor households. Considering the ever-increasing population and the resulting demand for construction poles, fuelwood, household utensils, farm implements, and the fast-growing performance of the species, Eucalyptus camaldulensis Dehnh. was the first preferred tree species to households for planting. Tree integration in the farming landscape should be recognized since it will be invaluable in developing plans for agroforestry interventions. However, exotic tree species have dominated the status of indigenous tree species. Then, there should be a continuous and detailed extension system to upgrade the traditional management system and the tree selection to be integrated.
Algorithmic support of the system of external observation and routing of autonomous mobile robots
Authors: Egortsev M. V. , Diane S. A. K. , Kaz N. D.
Published: June 2021

This article presents the algorithmic support of the external monitoring and routing system of autonomous mobile robots. In some cases, the practical usage of mobile robots is related to the solution of navigation problems. In particular, the position of ground robots can be secured using unmanned aerial vehicles. In the proposed approach based on the video image obtained from an external video camera located above the working area of mobile robots, the location of both robots and nearby obstacles is recognized. The optimal route to the target point of the selected robot is built, and changes in its working area are monitored. Information about the allowed routes of the robot is transmitted to third-party applications via network communication channels. Primary image processing from the camera includes distortion correction, contouring and binarization, which allows to separate image fragments containing robots and obstacles from background surfaces and objects. Recognition of robots in a video frame is based on the use of a SURF detector. This technology extracts key points in the video frame and compares them with key points of reference images of robots. Trajectory planning is implemented using Dijkstra’s algorithm. The discreteness of the trajectories obtained using the algorithm for finding a path on the graph can be compensated for on board autonomous mobile robots by using spline approximation. Experimental studies have confirmed the efficiency of the proposed approach both in the problem of recognition and localization of mobile robots and in the problem of planning safe trajectories.

Introduction: Viola plant has been used traditionally to treat neurological disorders. We aimed at determining whether pretreatment with Viola spathulata extract can alleviate the severity of ischemic-reperfusion damages and exert its protective effects through the regulation of a sodium/calcium exchanger (NCX3) gene expression in a rat brain. Methods: Male Wistar rats were divided into two main groups: one main group for evaluating Neurologic Deficit Score (NDS) and Infarct Volume (IV) and the other group for the evaluation of NCX3 gene expression in the brain tissue. The latter group was subdivided into the intact, control (vehicle), sham, V5, and V10. The vehicle (control) subgroup received Dimethyl Sulfoxide (DMSO), and V5 and V10 subgroups received V. spathulata extract at the doses of 5 and 10 mg/kg (IP), respectively, for 7 days. After pretreatment, we carried out Middle Cerebral Artery Occlusion (MCAO) for 60 min. Results: In the V5 and V10 subgroups, NDS and IV significantly decreased. MCAO upregulated NCX3 gene expression in the core, penumbra, and subcortical regions compared with the intact subgroup. The V5 subgroup significantly downregulated the NCX3 gene expression level in the core compared with the control subgroup. The V10 subgroup showed downregulation of the NCX3 gene expression level in the core, penumbra, and subcortex compared with the control subgroup. Conclusion: V. spathulata extract may have a neuroprotective role against MCAO-induced ischemic brain damage, possibly by preventing the alteration of NCX3 gene expression level.

Era l'ancoraggio territoriale a far lievitare forme peculiari di economie esterne, di vantaggi competitivi e di dinamiche endogene. Negli ultimi decenni, tuttavia, questi sistemi hanno attraversato cambiamenti multi-dimensionali a molteplice scala. Le nuove connotazioni strutturali - tra cui la prossimitŕ cognitiva, la

, la complementaritŕ di contratti formali e accordi informali nelle collaborazioni tra imprese, le reti translocali - richiedono un differente quadro teorico e comportano diverse implicazioni di policy. Il quadro teorico pone al centro la co-evoluzione di tecnologie, modelli organizzativi, culture e istituzioni. Entro la molteplicitŕ di traiettorie rese possibili da tale co-evoluzione, ciascun Ssl è sia correlato ad un sistema socio-tecnico che ne limita le dinamiche di mutamento, sia inserito in percorsi lungo i quali puň accedere in modi discontinui ad orizzonti tecno-economici lontani. Le implicazioni di policy debbono pertanto riferirsi alle traiettorie innovative che l'attuale transizione socio-tecnica globale rende possibili ad uno specifico gruppo di Ssl, che è nel nostro caso la Toscana. Sul piano strategico operativo - considerando i limiti politici e civili della societŕ in oggetto - tentiamo di cogliere alcuni cruciali "colli di bottiglia" che bloccano la percezione e il perseguimento degli interessi collettivi di lungo periodo. Questi blocchi riguardano la miopia cosě degli imprenditori come delle istituzioni pubbliche nei riguardi del potenziale tecnico-scientifico effettivamente accessibile e dei percorsi evolutivi che converrebbe imboccare; l'inadeguatezza delle forme istituzionali entro cui vengono prodotti e gestiti i beni comuni o

; la carenza di appropriati modi per capitalizzare le imprese innovative. Per ognuno di tali lock-in avanziamo proposte costruttive percorribili.
Innovazione e Ricerca e Sviluppo: la questione dell'organizzazione e del lavoro
Authors: Butera Federico
Published: June 2021

L'innovazione è un fenomeno più ampio di quello della ricerca e sviluppo: l'autore ne illustra le diverse tipologie. L'Italia dispone di una quota di risorse destinata alla R&S inferiore a tutti i Paesi sviluppati; i finanziamenti pubblici sono in proporzione più alti di quelli di altri Paesi; l'Italia, per numero di brevetti e di marchi comunitari registrati, è invece in una buona posizione e in costante crescita; forte è il contributo delle grandi imprese alla brevettazione, mentre modesto è quello delle medie imprese, praticamente nullo quello delle piccole imprese; tuttavia, il volume di innovazioni generate è molto più elevato: le innovazioni di processo (marketing, organizzazione, metodi, tecnologie di produzione, etc.) non brevettate e le innovazioni di prodotto incrementali sono molto più numerose del numero dei brevetti. L'articolo esamina le caratteristiche organizzative della Ricerca e Sviluppo che sono diverse da quelle di altre funzioni di impresa ma che hanno anticipato nuovi modelli organizzativi e in particolare le organizzazione organiche e quelle in rete. Viene presentato il modello di funzionamento basato sulle 4C originato nella R&S e poi diffuso nelle moderne organizzazioni: Cooperazione autoregolata, Conoscenza condivisa, Comunicazione estesa, Comunitŕ di lavoro.

Authors: Giullari Barbara , Masi Sara Elisabetta
Published: June 2021

Il paper illustra una ricerca che ha per oggetto lo studio del processo di policy making per la realizzazione del Programma regionale per la ricerca industriale, l'innovazione e il trasferimento tecnologico della Regione Emilia Romagna. La trattazione riflette sulla sfida posta dal passaggio da politiche lineari dell'innovazione a politiche sistemiche in cui l'innovazione è elemento cruciale degli output, ma anche ingrediente fondamentale del processo di

. In questa prospettiva il focus del lavoro di ricerca consiste nella ricostruzione del rapporto tra attori e contesto istituzionale per esplorare i processi di

che producono innovazione e l'individuazione del ruolo di imprenditori di policy.L'impostazione dell'analisi ha inoltre consentito di evidenziare le criticitŕ della retorica della convergenza nei processi di

locale dell'economia, attraverso lo studio comparato di due contesti locali in cui la politica per l'innovazione oggetto di studio è stata realizzata.
Quando la ricerca da pubblica si fa privata. Innovazioni organizzative in un caso studio
Authors: Murgia Annalisa , Tomasin Paolo
Published: June 2021

Lo studio dell'innovazione è un'area di ricerca in rapida crescita degli studi organizzativi. Tra i diversi punti di attenzione, la distinzione tra organizzazioni pubbliche e private ha rappresentato per lungo tempo uno dei temi maggiormente discussi. All'interno di questo ambito di studio, questo contributo si pone l'obiettivo di comprendere se la trasformazione di un istituto di ricerca da ente pubblico a fondazione privata costituisca di per sé un'innovazione organizzativa. Gli autori presentano uno studio di caso in cui vengono esplorate le dinamiche di trasformazione a partire da tre specifiche, ma interdipendenti, angolazioni: i processi di

; l'introduzione del primo contratto collettivo di lavoro privato della ricerca; le procedure amministrative e contabili. L'ultima parte è dedicata a rispondere in modo complessivo alla domanda di ricerca alla base di questo studio.
Il pre-embrione (non) è uno di noi: breve storia di una innovazione inter-organizzativa tra istituzioni, comunitŕ professionali e tecnologie
Authors: Perrotta Manuela
Published: June 2021

Innovazione e cambiamento sono temi centrali all'interno della sociologia del lavoro e dell'organizzazione, in particolare in relazione alla continua evoluzione delle nuove tecnologie. Il paper intende offrire un contributo teorico ed empirico al filone di ricerca degli Innovation Studies a partire da un caso empirico: l'emergere di un "nuovo oggetto scientifico" - il pre-embrione - come innovazione organizzativa all'interno di un network di elementi eterogenei distribuiti tra il setting istituzionale, le comunitŕ professionali coinvolte e le tecnologie della riproduzione assistita. Il caso appare particolarmente interessante alla luce di un approccio all'innovazione ispirato all'Actor Network Theory, poiché permette di analizzare un tentativo (fallito) di (ri)stabilizzazione del sistema attraverso l'attivazione di un network basato sull'appartenenza a diverse comunitŕ professionali, sulla mobilitazione di conoscenze scientifiche e sulla creazione discorsiva di un nuovo oggetto.
L'imprenditoria femminile come strumento di innovazione per lo sviluppo locale
Authors: Bertolini Sonia , Goglio Valentina
Published: June 2021

La valorizzazione dell'occupazione femminile è considerato un obiettivo strategico per lo sviluppo del paese, ma persistono ancora numerose difficoltŕ per le donne ad accedere a determinate posizioni ed occupazioni, in particolare la presenza delle donne rimane minoritaria nel campo dell'imprenditoria. Il presente articolo si propone di mostrare come l'imprenditoria possa essere una delle modalitŕ attraverso le quali far crescere l'occupazione femminile e contribuire all'innovazione dei sistemi produttivi locali. In particolare, la ricerca si concentra sul territorio della provincia di Cuneo, un contesto locale di "successo economico" ma allo stesso tempo portatore di valori tradizionali. I risultati di ricerca fanno emergere l'importanza del capitale sociale e delle politiche per il suo sostegno. In questo quadro è cruciale il contesto istituzionale in cui le imprese si collocano ed il contributo che le istituzioni pubbliche possono dare per una "costruzione sociale dell'innovazione".
Reti, attori, politiche e beni collettivi nei processi di riaggiustamento industriale in Lombardia
Authors: Tajani Cristina
Published: June 2021

Le reti formalizzate tra imprese e quelle tra imprese e istituzioni sono un fenomeno su cui la letteratura si è interrogata a lungo utilizzando sia una prospettiva economica, sia sociologica e organizzativa. Scopo del presente articolo è quello di indagare, in primo luogo, i meccanismi che presidiano la formazione di queste reti, al fine di meglio comprendere chi siano gli attori che gestiscono questi processi e il ruolo delle politiche (in particolare le modalitŕ di finanziamento all'innovazione) nella nascita della rete. In seconda battuta si guarderŕ ai beni collettivi per la competitivitŕ ricercati e generati da queste aggregazioni e al ruolo giocato, nella loro produzione, dai soggetti pubblici o misti a livello territoriale. L'obiettivo è quello di capire quali siano i beni collettivi funzionali alla riorganizzazione su base territoriale dell'economia e se - e in che modo - le istituzioni del territorio riescano a contribuire alla loro produzione. L'analisi si appoggerŕ sulla comparazione tra due casi di reti tra medie imprese di recente formazione, entrambe situate in Lombardia, ed entrambe sorte come esito intenzionale della gestione di importanti crisi aziendali.

The COVID–19 lockdown provided the opportunity to measure species biodiversity in urban environments under conditions divergent from regular urban rhythms. For 90 days, including weeks of strict lockdown and the subsequent relaxation of restrictions, we measured the presence and abundance of birds that were active at night at two sites in the city of Cali, Colombia. Our results show that species richness of nocturnal birds decreased 40 % to 58 % during the weeks with more human activity, adding further evidence to the biodiversity responses of the ‘anthropause’ on urban environments.

This research sought to determine the ideal percentage of soaking water from the tannery industry as a nutrient source for the microalgae Chlorella sp.; evaluating the effect of the initial concentration of 15, 30, 45, 60 and 75% of soaking water in contact with the microalgae in a first phase and a new evaluation with 30, 45 and 60% of soaking water using the adapted microalgae from the first phase into the second. Cell density over time was determined by cell counting in a neubauer chamber until reaching the stationary phase in all samples. The results show that the microalgae adapted to the effluent used present growth kinetics more similar to that of microalgae grown in a conventional medium. In the same way, it was determined that a better cell growth was obtained with a 30% concentration of soaking water. It is concluded that the use of soaking water is an efficient way to cultivate microalgae, thus helping to reduce pollution from tannery effluents.
