Authors: Singh Vijay Kumar , Hussain Md. Zahid , Kumar Subodh
Published: May 2021

Background: The morphological knowledge of the mandibular foramen is very important during
dental procedures involving lower jaw, as structures that pass through this foramen are at risk. Inferior
alveolar nerve (IAN) block is the most frequently used nerve block technique in dental practice. Location of mandibular
foramen is clinically important in Inferior alveolar nerve (IAN) block, dentoalveolar surgery planning, and various endodontic
treatments. Present study aimed to locate the precise location of mandibular foramen in relation to the borders of the
mandibular ramus, its distances from different bone landmarks on internal surface of ramus of dry mandible and incidence of
occurrence of accessory mandibular foramen in local population. Material And Methods: Present study was a cross-sectional
study of 50 (fty) dry adult human mandibles, obtained from the dissection room of the department of Anatomy, NMCH, Patna,
Bihar. Location of MF(Mandibular foramen) from various parameters was determined with digital Vernier calipers. The
presence of accessory mandibular foramen in and around mandibular foramen on the medial surface of mandibular ramus
was by simple visual observation with the help of a magnifying lens and their prevalence rate was noted. All the above
parameters were carefully documented and statistically analysed. Statistical analysis was done using SPSS version 23.
Student's t test was used as test of signicance to compare the mean values of right and left sides and a P-value less than 0.05
was taken to be statistically signicant. Results: Total 50 dry adult human mandibles were studied. The mean distance of
mandibular foramina to anterior border of ramus was 16.97 ± 2.13 (R) mm and 17.04 ± 2.72mm(L), to posterior border was (R):
13.73 ± 2.28 mm and (L): 14.16 ± 2. 05 mm, to mandibular notch was (R): 20.50 ± 2.11 mm and (L): 20.10 ± 2.82 mm and to
inferior border was (R): 26.93 ± 3.09 mm and (L): 26.37 ± 4.25 mm. We noted that there was no signicant difference in the
values on the right and left sides (p>0.05). All mandibles (100%) have bilateral mandibular foramen. Unilaterally Single
Accessory mandibular foramen was present in 11 (22%) mandibles. Unilaterally double accessory mandibular foramen was
present in 06 (12%). Bilateral double accessory mandibular foramen was noted in 02(04%) mandibles only. Bilateral single
accessory mandibular foramen was noted in 04(08%) mandibles. Conclusion: Present study provides valuable information
regarding distances between mandibular foramen and surgically encountered anatomical landmarks, which is very useful to
dental surgeons.

well as intra-operative and post-operative analgesia while maintaining haemodynamic stability, arousable sedation
and mild respiratory depression.
MATERIALS AND METHODS: Eighty patients aged between 18 and 60 years with ASA grade I or II posted for
elective upper limb surgeries were included in the study and were randomly divided into 2 groups with forty
patients in each. Group A received 0.5% ropivacaine (31 mL) and Group B received 0.5% ropivacaine +
dexmedetomidine 1microgram/kg (31mL). Both groups were compared for onset time and duration of sensory
blockade, onset time and duration of motor blockade , total duration of analgesia and associated side effects.
CONCLUSION : Dexmedetomidine as an adjuvant to ropivacaine in the supraclavicular brachial plexus block for
upper limb surgeries , significantly shortens the onset time and prolongs the duration of sensory and motor
blocks, with longer duration of post-operative analgesia , with associated significant sedation and a few
manageable side effects like bradycardia and hypotension.

Block-Sparse Recovery with Optimal Block Partition
Authors: Kuroda Hiroki , Kitahara Daichi
Published: May 2021

This paper presents a convex recovery method for block-sparse signals whose block partitions are unknown a priori. We first introduce a nonconvex penalty function, where the block partition is adapted for the signal of interest by minimizing the mixed l2/l1 norm over all possible block partitions. Then, by exploiting a variational representation of the l2 norm, we derive the proposed penalty function as a suitable convex relaxation of the nonconvex one. For a block-sparse recovery model designed with the proposed penalty, we develop an iterative algorithm which is guaranteed to converge to a globally optimal solution. Numerical experiments demonstrate the effectiveness of the proposed method.

A Simulink-based Channel Emulator for Underwater Acoustic Communications
Authors: Dey Indrakshi
Published: May 2021

The primary contribution of this paper is to develop a realistic yet mathematically tractable channel emulator for underwater acoustic communications (UWAC) channels. Our proposed emulator is based on the Wide-Sense Stationary Uncorrelated Scattering (WSSUS) assumption, where the channel samples are generated using finite sum-of-sinusoids (SOS) with uniformly distributed phases. The MATLAB-based Simulink platform and its associated block-set elements are used to generate numerical plots for amplitude distribution, Doppler frequency and channel impulse response. This Simulink-based design offers an added advantage over prevalent UWAC channel simulators, as it can be directly adapted to FPGA platform for hardware implementation.
Data-Driven Capacity Planning for Vehicular Fog Computing
Authors: Mao Wencan , Akgul Ozgur Umut , Mehrabidavoodabadi Abbas , Cho Byungjin , Xiao Yu , Ylä-Jääski Antti
Published: May 2021

The strict latency constraints of emerging vehicular applications make it unfeasible to forward sensing data from vehicles to the cloud for processing. To shorten network latency, Vehicular fog computing (VFC) moves computation to the edge of the Internet, with the extension to support the mobility of distributed computing entities. In other words, VFC proposes to complement stationary fog nodes co-located with cellular base stations with mobile ones carried by moving vehicles. Previous works of VFC mainly focus on optimizing the assignments of computing tasks among available fog nodes. However, capacity planning, which decides where and how much capacity to deploy, remains an open and challenging issue. The complexity of this problem comes from the mobility of vehicles, the spatio-temporal dynamics of vehicular traffic, and the computing resource demand generated by varying vehicular applications. To solve the above challenges, we propose a data-driven capacity planning framework that optimizes the deployment of stationary and mobile fog nodes to minimize the installation and operational costs under the quality-of-service constraints, taking into account the spatio-temporal variation in computing demand. Through real-world experiments, we analyze the cost efficiency potential of VFC in long term and demonstrate that the performance loss of VFC is below $6\%$ compared to stationary deployment with equal network capacity. We also analyze the impacts of traffic patterns on the potential cost saving. The results show when the traffic density is higher, more operational costs will be saved in the long run due to more dense deployment of mobile fog nodes.

The geospace stratification substantiate and its spatial differences reveal based on the analysis of the economic growth dynamics. The impact of the COVID-19 pandemic on the slowdown in economic growth confirmed and its negative consequences for the investment sphere clarified, because the ability of countries to respond adequately to these processes is different. It has been determined that under the globalization influence, the world acts as a single whole, and the core of developed countries and the periphery is formed as well as local civilizations are transformed. Attention focuses on the research of the values problems that determine the state of society development. The research of the essential characteristics of civilizations carried out and the ideas of the main European civilizational schools characterized. Based on M. Rokeach’s concept, the features that characterize values are determined. It confirmed the values that dominate in society are the main element of culture. The model for measuring the cultural variability of the cross-cultural plane, which was developed by the Dutch psychologist G. Hofstede, is detailed, and the influence of cultural characteristics on the new economy formation is analyzed. The «World Values Survey» study has been assessed. It confirmed that, due to the impossibility of full-fledged self-realization of the individual, migration processes activated and their analysis shows a tendency towards growth. It substantiated that in the modern world the questions about the nature of the socio-cultural integrity of civilizations and civilizational ecumene, associated with religious differences and demographic processes, remain unresolved. An assessment of the demographic situation in the world carried out and its growing dynamics and regional asymmetries clarified. A spatial analysis of the distribution of countries in the global space with dominant religions carried out and the main trends in the world religions development revealed. The role of strengthening the intangible component in the structure of modern economic reproduction argues. It confirmed that the potential of the countries and the world development as a whole takes place in the process of deepening cross-civilization-integration processes. The main civilizational challenges of global economic development are formulated, they are formed under the multi-vector processes in the world, including: spatial asymmetry of countries’ development, universalization of values, socio-cultural differences, ethnic problems, religious differences, demographic and migration processes.

The clear outline of the economic policy motives in the tourism industry of Ukraine, the specification of the purpose of entering the domestic market of tourist services, the formation of the optimal strategic model based on adequate marketing measures, and the opportunity to optimize the process of managing the marketing activities of domestic tourism businesses are the prerequisites for the intensification of marketing activities in tourism. The purpose of this article is to define the role of marketing as a tool in managing the innovative development of the tourism sector of the region. The article proposes a method of a step-by-step study of the marketing environment for domestic touristic entities. The essence of this method is to determine the sequence of research of the target domestic market by business entities based on the analysis of several important factors of the marketing environment. The paper proves that determining the model of the presence of domestic businesses in the market is an important tool for efficient marketing. Marketing analysis has shown that the state tourism policy is the determining factor in the market of tourist services in Ukraine. The directions of activity of the regional marketing stimulation authority are determined. Most legal regulations governing tourism are not properly enforced, which hampers the solution of many pressing problems in the tourism industry. Measures to improve the regulatory framework should be aimed at creating favorable conditions for the development of domestic tourism business and real economic mechanisms to stimulate the development of the tourism industry. Today, the domestic tourist market, including the market of industrial tourism services, faces the task of integration into the European tourism space. At the same time, in order to achieve the possible benefits of integrating cooperation, Ukraine's tourism policy should be aimed at meeting the requirements of the Member States of the European Community and providing the necessary radical changes at all levels of management of the industrial tourism market.

Elementos do saber profissional do professor: uma geometria para ensinar do final século XIX
Authors: Santos Fortaleza Francisca Janice dos , Chaves Rocha Maria Lúcia Pessoa
Published: May 2021

Este artigo apresenta resultados parciais da tese de doutoramento da primeira autora, que está alinhada a um projeto amplo de investigação. A tese objetiva caracterizar uma geometria para ensinar a partir de manuais de pedagogia direcionados à formação de professores dos primeiros anos escolares, 1870-1920. Neste artigo, pretendemos caracterizar a geometria para ensinar que se manteve estável como elemento do saber profissional do professor na última década do século XIX, considerando os manuais de Affreixo e Freire (1890) e Coelho (1892). Essa caracterização aconteceu conforme determinações sobre como transformar informações dispersas em saberes sistematizados. Observamos que as orientações para ensinar geometria sistematizadas pelos autores estão pautadas em princípios do método intuitivo que mobilizam as formas geométricas planas e espaciais. Então, sistematizamos elementos de uma geometria para ensinar que nos levaram a caracterizar a geometria que se manteve estável enquanto saber da cultura profissional do professor como geometria intuitiva para ensinar.

SPATIAL ANALYSIS OF PROSTATE CANCER INCIDENCE IN IRAQ DURING 2000-2015
Authors: Mohammed Al-Hashimi Muzahem
Published: May 2021

Prostate cancer incidence rates have evidenced a substantial increase in Iraq over the past sixteen years. Geographic variation of prostate cancer in Iraq has not been explored. We examine the geographic incidence patterns of prostate cancer in Iraq using the global index of spatial autocorrelation, Getis-Ord Gi* and Anselin Local Moran’s  to detect hotspots, coldspots, and spatial outliers of prostate cancer rates. We calculated the age-adjusted incidence rates (AAIRs) according to district level for three periods (2000-2004, 2005-2009, and 2010-2015). Disease maps were produced to explore whether prostate cancer incidence clusters by district, and where hotspots and coldspots occur. Results highlight several districts of Iraq where the burden of prostate cancer incidence is especially high. In 2005-2009, the spatial autocorrelation analysis revealed a prostate cancer incidence hotspot in Al-Rissafa, Al-Manathera, Al-Kufa, Al-Hilla, Al-Hindiya, and Kerbela district. In 2010-2015, hotspots were seen in Al-Mussyab, Al-Hilla, Al-Hindiya, Al-Rissafa, Al-Adhamiya, Al-Sadir, and Daquq district. Examining spatial pattern of prostate cancer AAIRs is critical to government efforts to focus on those regions, and to understanding and targeting prostate cancer

Published: May 2021

In keeping up and expanding soil fertility by applying siderite (green manure), increasing the yield of cotton by planting and cultivating pisum, pea, rapeseed, and grain as siderite crops from selected plants; amid cultivation, 39-51 tons of green biomass per hectare was collected in summer and 17-22 tons in autumn, and their effect on weed numbers were determined. In this case, in the experimental field, more perennial weeds were found, such as salomalaykum (Cyperus rotundus L.), field bindweed (Convolvulus arvensis L.), ajrik (Cynodon dactylon (L.) Pers.), and annuals were found in semizoot (Portulaca oleracea L.), white sorghum (Chenopodium album L.), common rosemary (Amaranthus retleflexus L.), ituzum (Solanum nigrum) and others were observed. As a result, the number of yearly and perennial weeds beneath the influence of summer sideration diminished by 2.4-2.6 units compared to the control option before the 1st cultivation between cotton rows, and by 4.6-4.7 units before the final irrigation, or under the influence of autumn sideration. In accordance with the over, a decrease of 2.8-3.1 units was accomplished, and before the final irrigation - to 5.0 units. The most noteworthy reduction in weeds was observed in rapeseed and barley variants utilized as siderates in both experiments.
