Authors:   Huai Hao Khor, Pei-Fen Lin
Published: March 2022

Sphenoid wing meningiomas commonly present with headaches and visual changes. Some presentations may vary depending on the meningioma’s site of growth. Here we present a gentleman with no headaches, a very mild proptosis that went unnoticed, together with a rapid visual loss that progressed over 4 months. Prior to presenting at the eye casualty, he has been assessed by other doctors and opticians, who diagnosed his fundal toxoplasmosis scar as the cause of his visual loss. Only through a thorough examination and measurement, did the mild proptosis become a significant part of the investigations and diagnosis. Neuroradiological investigations confirmed a diagnosis of spheno-orbital meningioma, for which he underwent 2 surgeries to achieve satisfactory debulking of the mass. This case report is to highlight the importance of having a systematic approach when reviewing patients with proptosis, and to always explore other potential causes for visual loss. A brief review of literature looking at the various causes of unilateral proptosis and different presentations of spheno-orbital meningiomas is included.

The article describes the biological, morfological and economically valuable features of eastern persimmon grades from the General Collection of FRS SSC RAS. The collection includes 23 cultivars. As a result of many years of research highlighted varieties, which contitute pistillate, staminate and formed not every year flowers. It has been established, that in order to obtain heavy yields and quality fruits, most varieties of eastern persimmon need pollination. Varieties in need of compulsory pollination have been identified (‘Hiakume’, ‘Zenji-Maru’, ‘Kuro-Kuma’, ‘Geili’). On quality of fruirts all gradres are devided into three groups – tart ( ‘Seedles’, ‘Hachia’, ‘Tamopan big’, ‘Gosho’, ‘Nitari’, “MVG Omarova”, ‘Kiara constant’,‘Nikitskaya burgundu’, ‘Roman Kosh’, ‘Gora Goverla’, ‘Gora Rodgers”, ‘Novelty, ‘Rojo Brilliante’), not tart (‘Djiro’, ‘XX Century’, ‘Fuyu’, ‘Geili’), and varying (‘Khostinskiy, ‘Hiakume’, ‘Zenji-Maru’, ‘Kuro-Kuma’, ‘Kiara varying ’, Hybrid №39).By weight of the fruit, varieties are divided into three groups - small (100-120 g), medium (120-160 g), large (160-200 and more grams). To increase the conveyor of entry into the market of fresh persimmon fruits, varieties of different maturation period are highlighted - early (October), middle (late October - early november) and late (late November - early December). Low-growth varieties (2.5-3.0 m) are distinguished; strong varieties (4 meters or more) and medium-layered varieties that prevail in the collection (3.0-4.0 m).Two new varieties of eastern persimmon bred – ‘Khostinskiy’ and ‘MVG Omarova’. Fruits are characterized by high sugar content - 26.80%, which is 8-10% higher than in other varieties. Hybrid №39 is highlighted as promising, is a candidate in the variety and undergoing testing in State breeding centers.

The problem of today is the high concentration of cars in cities, associated with the growth of the number of personal cars. The capacity of city streets is much less than the number of cars, so traffic is accompanied by traffic jams in front of traffic lights. It is concluded, that with such a rhythm of movement, time losses, wear of engine parts and vehicle systems and harmful emissions significantly increase.
Device for prevention of mobile machine engines starting in the rack with violation of instruc-tions
Authors: Shkrabak Roman Vladimirovich
Published: March 2022

The agro-industrial complex is a stable consumer of mobile means of mechanization in a wide variety of industry activities almost every day and around the clock. This is required by various types of life, dictated by the specifics of production (livestock, poultry, horticulture, open and closed ground, storage, processing and sale, etc.). The needs of production are characterized by a variety of units, the prevailing of which are tractors, automobiles, harvesters. All of them are powered by combustion engines and transmissions with different numbers of gears. The frequency of using the latter is dictated by the type of work and their technology. The practice of using such units is characterized by their frequent installation and engine shutdown (technological and technical failures, technological needs, breaks, etc.). The operating requirements provide for the fixation of the units when parked with a hand brake and a gear engaged, excluding spontaneous rolling due to the relief of wind loads, etc. when diesels are started by starting engines and when operators are between the front and rear wheels. Such assaults usually end in severe or fatal outcomes, the number of which in the agro-industrial complex is averaged about 45 people annually. In order to exclude such a situation, an innovative locking device has been proposed that excludes automatically stated situations and related injuries. The performance of the device has been confirmed by laboratory tests.
Entropy Analysis for Modbus Traffic over TCP/IP in Industrial Control Systems
Authors: Day Logan , Ghosh Tirthankar , Bagui Sikha , Bagui Subhash
Published: March 2022

Anomalies in network traffic are usually detected by measuring unexpected deviation from what constitutes a baseline. Several statistical techniques have been proposed to create baselines and measure deviation. However, simply looking at traffic volume to find anomalous deviation may result in increased false positives. Traffic feature distributions need to be created, and deviations need to be measured for these features. An effective approach to finding anomalous deviations starts with entropy analysis on these features. In this paper, we presented an initial entropy analysis on an industrial control system network using selected features with datasets obtained from an HVAC system. We started with the fundamental question: whether a preliminary entropy analysis on Modbus-over-TCP data using only a few TCP/IP features without going into the Modbus traffic itself gives us information about an anomaly in the network. We acknowledge that the initial entropy analysis provides only a starting point that would lead to several questions and investigating relevant issues resulting in an optimal system design and implementation. *

Authors: Vadwala Ayushi , Jin Ying
Published: March 2022

There is a lot of uncertain and imprecise information in a real-world scenario. Graph database systems based on the graph model support crisp and precise data. This paper presents a system structure that processes fuzzy quantified queries in the context of a graph database. Fuzzy logic allows decisions to be taken more realistically. A specific form of structural quantified query is designed and demonstrated in this paper, which then can be expressed as an extension to the Neo4j Cypher query language. In addition, this research built an active rule system on top of the graph database that reacts to event occurrences automatically. This paper presents our approach of supporting temporal event handling using fuzzy active rules and fuzzy query processing over Neo4j graph database systems.

Published: March 2022

In recent days, the uses of Internet of Things (IoT) applications have been growing enormously. IoT considers the integration of business process models or process execution with resources of intelligent devices. The concept of process meta store (PMS) [1] optimizes the interactions between IoT devices and business processes. However, the mechanism of PMS highly depends on the meta-information of the system, associated devices, and interactions among them. In this context, a novel semantics of meta- information of process store (MIPS) for IoT-based applications is proposed in this paper. The semantics of various MIPS elements and their relationships are described using a class diagram. Further, a B+ tree-based indexing approach for the MIPS semantic is presented for efficient searching of meta-information. The semantics of MIPS are illustrated using the case study related to the clinical decision support system (CDSS). Moreover, a detailed comparative analysis has been carried out to show the expressiveness of MIPS.
Carbon Bed Interflow Performance Prediction Using Variable Hypothetic Pressure Wave Cycles Model
Authors: Caryana Yusep K
Published: March 2022

The nature of low productivity of CBM well experiences represent low interflow performace over matrix and fractures in coal bed. Therefore, to increase CBM well production rate, it is necessary to improve the interflow performace. An approach to improve the interflow performance is to find out the possibility of increasing gas flowrate in carbon bed taken into account factors dominantly effect on the performance. For this purposes, Variable Pressure Wave Cycles Hypothetical Model has been developed based on Pressure-Swing adsorption - desorption (PSA) technique commonly applies in natural gas separation using carbon active bed. Preliminary simulation of the model has been carried out using data related to carbon bed taken from previous studies. Variables in the simulation are kinetic constant and hypothetic pressure waves generated which is required to increase gas flow rate in the bed. The simulation results demonstrate the possibility of interflow performance improvement in carbon bed. However, this improvement is asymptotically limited to maximum amount of gas desorbed from carbon bed as well as Langmuir Isotherm pattern application for gas desorption from coal. Moreover, the simulation of the model shows the sensitivity of gas interflow performance to hypothetical pressure waves generated and kinetics controlling adsorption/desorption mechanism and mass transport in carbon bed.

Published: March 2022

Oil sludge from petroleum industry effluent is classified as hazardous waste and requiredspecial treatment before discharge to the environment. Biodegradation using bacterialactivities is a general treatment for oil sludge processing. However, the bacterial abilityin oil sludge biodegradation is blocked by non-aqueous phase liquid of oil sludge. Twopossible ways of enhancing the bioavailability of oil sludge are surfactants application and slurry bioreactors system. The objective of this study is to obtain the surfactant which can increase oil sludge biodegradation using simple slurry bioreactor. The surfactant selection obtained Emulsogen LP (58% effectiveness) which was examined based on HLB value, nonionic character, and surfactant effectiveness. Emulsogen LP is readily biodegradable which reached 93% biodegradability in 15 days. The biodegradation test showed that Emulsogen LP addition on its Critical Micelle Concentration (10 mg/L) enhanced oil sludge biodegradation in 3 bacterial cultures of Pseudomonas aeruginosa, Bacillus subtilis, and Actinobacter baumanni after 48 hours. By surfactant addition, oil sludge biodegradation reached 37-49% whereas without surfactant addition it only reached 28-33%. The highest oil sludge biodegradation was obtained in P. aeruginosa cultures with Emulsogen LP addition (49%). The surfactant addition had no effect on microbial growth. Moreover, P. aeruginosa population was increased by surfactant addition.

Published: March 2022

Combustion of gas with diffusion system is widely used in many residential gas appliances like stove, engine furnaces and industrial furnaces. Phenomenon of lifted flame is often happened at diffusion flame where the stream of fuel and air into combustor flow separately. Hence the combustion process needs time so that mixing of air and fuel reach the condition ready for burnt. This condition make the burner tip protected from high thermal load and more safe to operate. In this paper, propane was ejected into quiescence air through nozzle having 1.8 mm holes diameter. Fuel flow rate was increased until liftoff conditions exceed; hereinafter flow rate of fuel was made constant at 69 ml/s and air was ejected around of fuel with axis symmetric flow. Liftoff behavior of diffusion flames was investigated for various air flow rate: 17.9 ml/s – 89.9 ml/s. Lifted distance decreased from 130 mm to 90 mm when air was injected with flow rate of 19.1 ml/s, however, it increased to 100 mm when air flow rate increased to 35.9 ml/s. Cold-flow simulation showed the moderate air flow rate give a faster density degradation at axial line compared to larger air flow rate. It means moderate flow rate of air support a better air-fuel mixing than faster one.
Carbon Capture And Storage (Ccs) - Enhanced Oil Recovery (Eor): Global Potential In Indonesia
Authors: Iskandar Utomo Pratama , Syahrial Ego
Published: March 2022

Total global CO2 emissions from fossil-fuel will still increase in the next ten decades. These are attributed to the heavy reliance of human activities with fossil fuels. The uncontrolled CO2 emissions from combustion of fossil fuels cause the CO2 concentration alteration in the atmosphere. As the result, this phenomenon cause global warming and change the climate globally. In the future, CO2 emissions are predicted in range from 29 to 44 GtCO2/year in 2020. Therefore it is necessary to abate the CO2  missions to the level that would prevent dangerous anthropogenic interference to the global climate system. The growth of energy efficiency improvements, the switch to less-carbon intensive fuels and renewable resources employment is still low in the context CO2 emissions mitigation. Carbon Dioxide Capture and Storage (CCS) as a third option for these mitigation options might facilitate achieving CO2  missions stabilization goals. As a part of the commitment and participation on combating the global warming, Indonesia has signed the Kyoto Protocol in 1998 and ratified it in 2004 through Law No. 17/2004. On the other side, Indonesia oil production has been declining since in the last ten years but demand for this energy is still high. In this frame CCS-Enhanced Oil Recovery (EOR) by CO2 injection might answer the global warming challenges and alongside contribute to increase the oil production in the near future. This paper presents a preliminary study of CCS-EOR potential in Indonesia. A brief explanation of geological setting and reservoir screening for site selection also presented. Then some discussions about CCS-EOR global potential will be highlighted as well as the analysis. It is hoped that this study would provide a standard guideline for determining CCS- EOR potential in Indonesia.

Distributed Leadership Theory for Investigating Teacher Librarian Leadership
Authors: Johnston Melissa P.
Published: March 2022

The ever-evolving and complex technological environment of 21st century schools and the new leadership capacities that accompany it have signified a paradigm shift in leadership. Distributed leadership has emerged as a possible method for dealing with the increased responsibilities and pressures placed upon school principals. Distributed leadership theory is proposed as a means of in-depth analysis of the practice of school leaders in order to understand the dynamics of leadership practice and proposes that leadership function is stretched over the work of a number of individuals (Spillane, 2006). This theory, the concepts, propositions it contains, and the research evolving from it present a means for exploring and analyzing the leadership activities, actions, and roles of teacher librarians. The applicability of distributed leadership to teacher librarian leadership will be demonstrated through this report of research that applied distributed leadership theory to investigate the enablers and barriers to teacher librarian technology integration leadership.

Analysis on household benefits of cocoa rehabilitation and regression in Liberia Cocoa Belt
Authors: David P. Tokpah
Published: March 2022

The status of smallholder cocoa farms in Liberia's cocoa belt is investigated in the present study (Bong, Lofa, and Nimba Counties). Furthermore, the first part of the study focused on a household survey among cocoa farmers, with the results published in a separate report in 2016, and the second part of the study focused on road rehabilitation, cocoa marketing, and the state of cocoa farms. Farmers reported that the quality of their cocoa farms had improved slightly. Farm management practices remain at a basic level, resulting in low productivity (e.g., everyday input use and the predominance of local cocoa varieties). On cocoa farms, pests and diseases such as rodents and black pod disease are common. In terms of cocoa production and income, there are significant regional differences, with Lofa farmers producing and earning the least compared to other cocoa farmers in Bong and Nimba Counties. Cocoa farm rehabilitation appears to be more closely linked to cocoa income than cocoa production. The effects of cocoa rehabilitation that can be seen are still inconclusive. Cocoa production and revenue have increased since the baseline study, and this is true for both participants and non-participants in cocoa rehabilitation projects. The value of a household's goods and assets has no strong relationship with cocoa rehabilitation or cocoa revenues. These outcomes at the household level are strongly linked to household characteristics (gender and head of household, household size, and permanent illness within the household). According to a study on household food security and cocoa income, cocoa rehabilitation could indirectly contribute to food security. Secondary and primary roads in Lofa County, Guatemala, are being repaired, which helps people have enough food to eat. The findings show that cocoa farm conditions need to be improved; cocoa practices are still at a basic level, so more investment is needed to make significant changes in Liberia's cocoa sector. It is not so much a question of whether or not farmers are interested in cocoa rehabilitation, but rather whether or not they are aware of and eligible for assistance.

Indomethacin, an anti-inflammatory agent used for pain, fever and inflammation, causes severe lesions in the gastrointestinal tract in humans and animals. For this reason, there has been an increase in the search for new compounds that can help prevent and/or alleviate these lesions caused by indomethacin. The aim of the present study is to evaluate the gastroprotective effect of Juglans regia administration against indomethacin induced gastric lesion. A total of forty rats were divided equally among four groups for the experiments. Groups were designed as Control (C), Indomethacin (IND), Juglans regia + Indomethacin (JR+IND), and Pantoprazole + Indomethacin (PAN+IND). Following the 7-day adaptation period, substance applications (pantoprazol and Juglans regia extract) were made for 10 days. In the IND, JR+IND and PAN+IND groups were administered indomethacin 100 mg/kg single dose on day 11th. Indomethacin caused significant increases in the stomach IL-6 and TNF-α levels compared with the C group (respectively, p<0.001, p<0.01). In the PAN+IND and JR+IND groups showed a significant lower in the IL-6 levels compared with IND group (respectively, p<0.001, p<0.01). The C-reactive protein (CRP) and Cyclo-oxygenase-2R (COX-2R) levels of IND group were increased compared to C group (p<0.001). There was a significant decrease in CRP and COX-2R levels after PAN and JR treatment compared with IND (p<0.001). COX-2, CRP and proinflammatory cytokines is seen as the main target for the treatment of inflammatory diseases. As a result; it was determined that JR has a protective effect, which may be related to decrease inflammatory markers, against of gastric damage caused by indomethacin.
Features of water vapor sorption by cellulose materials
Authors: Michael Jacob Ioelovich
Published: March 2022

In this research, the sorption of water vapor (WV) by various cellulose samples (microcrystalline cellulose, cotton cellulose, Kraft pulp, mercerized cellulose, and rayon fibers) has been studied. The sorption isotherms of WV for various samples have a sigmoid shape. To describe such isotherms, various models have been proposed, including mono- and multimolecular adsorption, formation of hydrates and solid solutions, as well as mixed models combining various sorption mechanisms. After critical analysis of known models, the improved absorption model was proposed to explain the interaction of VW with cellulose samples. It was confirmed that crystallites are inaccessible for water, and therefore water molecules can be trapped only by polar groups of non-crystalline (amorphous) domains of cellulose materials. The developed model permitted obtaining the general absorption isotherm of water molecules in amorphous domains of cellulose. Moreover, the equation was derived, which describes both the general isotherm and isotherm of any semi-crystalline cellulose sample, when its crystallinity or amorphicity degree was pre-determined. Based on the proposed absorption model, various characteristics can be found, e.g., degrees of amorphicity and crystallinity, the maximum amount of absorbed water, the specific surface area of wet cellulose sample, the amount of capillary condensed water, etc.

The forests of Papua are large enough to support a diverse range of flora and fauna and other natural resources such as mining materials. PT-Freeport Indonesia, one of the world's largest mining companies, has an ex-mining area (tailing) managed as a reclamation area. Regular biotic and abiotic factor interactions will aid in the success of reclamation efforts. Soil organisms, which act as decomposers, are biotic factors that contribute to soil fertility and bioindicator. Collembola is a soil microorganism that is very important in marginal soils and can help soil fertility naturally. This study aims to assess the differences between the Collembola communities in the tailings and plantation areas. The method employs a literature review, which refers to a literature review, and it uses secondary data from the PT-Freeport Indonesia Biodiversity and Reclamation Sub Division. Collembola population and diversity are classified as low in the tailings area, presumably due to limiting factors for the sub-alpine and alpine ecosystem types, making it longer. Unlike in the tailing area, the Collembola population and diversity are classified as moderate to high in the plantation area because of litter availability as a source of nutrients for Collembola activities.

As an archipelago dominated by small islands, Maluku has a high wealth of biological and non-biological natural resources.  This is influenced by the region's geographical location between the Asian zone and the Australian zone, the Oriental area. One of the indicators that can be used to find out is Australian wild animals and Asian wild animals in Maluku. Traditional people in Maluku, since their ancestors have been conservation of natural resources causing its availability can still be enjoyed by the current generation. The research aims to find out the forms of legal protection and the process of application to natural resources in the South Leitimur Subdistrict. The observed variables are traditional forms of conservation and their application process. The study required 27 people as respondentsâ€”research using direct and indirect Survey methods.  Data collection is done by conducting interviews, filling out question lists and field observations. The data collected includes primary and secondary data. The results showed that traditional forms of conservation of natural resources in the South Leitimur Subdistrict are Sasi, Sacred Places, and Pamali. The application process has similarities that Sasi is applied at sea and on land. At the same time, Pamali and sacred places are prohibited from being crossed because it is believed to be dangerous or full of mystery.

This research aims to analyze the success rate of community forest management, analyze driving factors and inhibitory factors, and formulate strategies for the development of community forest management. The data obtained is identified and reviewed through a table of criteria and indicators then analyzed descriptively through the Methods of Force Field Analysis and Analysis Hierarchy Process. The results showed that community forest management in the Kindang District of Bulukumba Regency succeeded with 2.2. The driving factors of community forest management are stakeholder assistance, community involvement in land use, internal rules of groups and work programs, the service of productive economic tools, and the implementation of a good agroforestry system. The inhibition factor consists of the involvement of members of forest farming groups in non-maximal management, non-routine meetings, no socialization related to community forest policy, utilization of natural attractions has not been optimal, the lack of socialization of forest protection and security, and non-participatory patrol activities. The proper management development strategy consists of conducting regular meetings involving various parties, socializing related to community forest policy, applying each group of forest farmers in strengthening human resource capacity, land use, and maximum productive economic tool assistance, the preparation of a master plan of tourist attractions and participatory forest protection and security activities.

Natural antioxidants – an alternative for reduction of nitrites in cooked meat products
Authors: Kolev Nikolay Delchev
Published: March 2022

Nature is a source of natural additives that can be incorporated into the meat products’ matrix. Extracts from spices, herbs, nuts, fruits and vegetables are most common. The extracts can be from whole, individual parts, and from various waste products. Those extracts can be used in meat products for various purposes. They are rich in substances with antioxidant properties, such as anthocyanin, vitamins and polyphenols. Those substances are capable of inhibiting lipid and pigment oxidation, prolonging shelf life and at the same time having a positive effect on organoleptic characteristics. Sodium nitrite is almost essential ingredient in production of cooked meat products. Strict regulated use, the existing risk of carcinomas and even the direct toxicity of nitrites lead to increased interest in search of natural antioxidants. It is believed that they can maintain the quality characteristics of meat products with reduced nitrite content. In the past decade there is a growing interest in the search for, certification and implementation of safe natural additives. The growing demand for the so-called "clean label" foods is the driving force for many of the conducted researches in the last two decades.
