Expansión metropolitana de la ciudad de Managua
Authors: Gutiérrez Lanza Danna
Published: December 2021

Este artículo indaga sobre los factores y características del fenómeno de expansión urbana a fin de encontrar en las cualidades la lógica explicativa al desarrollo urbano más allá de la dimensión física del mismo. Los resultados permiten caracterizar una expansión a nivel metropolitano que comparte características de desarrollo espacial con el resto de las ciudades en Latino América, y que encuentra su impulso en un modelo de urbanismo neoliberal, a saber: acelerado crecimiento suburbano, caracterizado por su baja densidad y su extensión más allá de los límites urbanos.

La transferencia de facto de las capacidades de gestión desde las entidades estatales hacia el mercado como agente primario del desarrollo urbano han dado como resultado una expansión urbana horizontal que profundiza las desigualdades urbanas y las inequidades sociales en una ciudad que cada vez más se caracteriza por un desarrollo fragmentado de enclaves funcionales y llevado hacia adelante a través de la inversión en innovaciones espaciales.

En Nicaragua, específicamente en la ciudad de Managua, es posible observar cómo estas condiciones consolidan la tendencia al aislamiento y la fragmentación del tejido urbano. La inversión privada sobre ejes viales y a través de proyectos habitaciones como “innovaciones espaciales” avanzan a través de la habilitación de tierra no urbanizada, incidiendo en cambios en la relación funcional entre los centros urbanos y entre estos y las zonas habitaciones en las áreas interurbanas.

Study and Analysis of Photonic Crystal Fiber for Broadband Laser Source Design
Authors: Faisal Mohammed , Kabir SK.M. Jahangir
Published: December 2021

Photonic Crystal Fiber (PCF) has been a topic of extensive research in the field of nonlinear fiber optics. It is due to its combination of linear and nonlinear properties which ultimately results in the phenomenon having various types of applications. One of the phenomena is supercontinuum generation that has been extensively studied numerically and experimentally over the last few decades as it has important applications in the field of medical imaging and sensing. In this paper, we numerically analysed and studied PCF of hexagonal core with various parameters and propose our novel ‘Star in Hexagon’ design as a good candidate for the broadband supercontinuum generation and hence a broadband laser source. We numerically pumped a long 10 mm PCF of this kind at 3.1 um wavelength with a pulse having a power of 4000 W and a temporal width of 50 fs. A broadband supercontinuum ranging from 1.7 um to 18 um was obtained. The generated spectrum is quite well in the mid-infrared region. Hence it can be utilised for Mid – Infrared (MIR) applications.

Published: December 2021

A reasonable number of studies on the effect of Female life expectancy (FLE) upon the quality of women's lives in developed countries have been done. Bangladesh lacks such a study. We explore the effect of decreasing fertility and childhood mortality rates on FLE in Bangladesh and evaluate the potential impthe act of the demographic transition on GDP. Also, we investigate the trends and patterns of different factors from 1995 to 2018. Partial Least Squares-Structural Equation Modeling (PLS-SEM) is functioned to fit an appropriate model to link fertility, GDP, and childhood mortality with FLE. The significance of the relationships has also been assessed. Results indicate that declines in fertility and childhood mortality have made significant improvements in FLE. The prospects of demographic transition due to fertility decline have been analyzed, and challenges to achieve it are highlighted.

Authors: Battagliola Davide
Published: December 2021

This contribution aims to offer new insights into the context of the manuscript Paris, Bibliothèque nationale de France, fr. 1822. Keith Busby has recently ascribed this miscellany of Old French moral texts (sole witness of Jofroi de Waterford’s translations) to the Irish city of Waterford. The paper discusses this hypothesis, focusing on the codicological and historical aspects of the manuscripts. Moreover, the article presents my research on the (probably Anglo-Norman) redaction of the Livre de Moralitez transmitted by the codex.

Architravi scolpiti del XII secolo a Piacenza
Authors: Ferrari Jessica
Published: December 2021

Il saggio è dedicato all’analisi stilistica e iconografica di alcuni architravi scolpiti che ornano i portali delle chiese di Piacenza, una delle località più vivaci nel panorama artistico nord-italiano del XII secolo. L’eredità delle opere realizzate per la cattedrale cittadina dalla bottega di Nicholaus riecheggia nei rilievi delle chiese di San Matteo, Sant’Ilario e dell’inedito portale di Santo Stefano.

Attraverso lo studio delle testimonianze storiche superstiti, il confronto con opere del medesimo periodo e contesto e una rinnovata attenzione per i contenuti iconografici, l’intento del saggio è quello di dimostrare la portata simbolica delle raffigurazioni ospitate sugli architravi. Un’attenzione particolare è riservata alla inusuale iconografia dell’Incredulità di san Tommaso presente sul portale della chiesa di Sant’Ilario. Il tentativo di rilettura delle iscrizioni e l’inquadramento di tale opera nel contesto socio-culturale della Piacenza di tardo XII secolo permette di formulare nuove ipotesi sulla connessione tra scelte iconografiche, istanze di rinnovamento spirituale della società e rituali liturgici, sottesa alla realizzazione di sculture che ornano significativamente le porte di accesso ai luoghi sacri, vie di salvezza per i fedeli penitenti.

This study was carried out to investigate the effect of two different doses of oxytocin on weight. Adult male rabbits (15) were weighed and provided with food twice daily for 3 weeks to determine the amount of food consumed daily and the time spent feeding by each rabbit.  After 3 weeks the rabbits were weighed and divided randomly into 3groups: the control group, the low dose group, and the high dose group. The animals were injected daily for 3 weeks. During that time the amount of food consumed and the time spent feeding in both periods were determined. After the end of the treatment period the rabbits were weighed, and sacrificed. The results of this study showed that before treatment the rabbits consumed more food in the evening period than they did in the afternoon period. The mean time spent feeding in the evening period was slightly higher than that spent in the afternoon period; however, this difference was not statistically significant. After treatment, there was still significant difference between the means of the consumed food in the afternoon and the evening period for the control group. The mean amounts of food consumed in both periods by the treated groups were slightly reduced, but this reduction was not statistically significant. Furthermore, the mean time spent feeding in the evening period was slightly higher than that of the afternoon period for the 3 groups; however, these differences were not significant. The mean weight of the control group was slightly increased after treatment with the hormone; and the mean weights of the treated groups were slightly reduced after treatment. However, changes in body weighs were not statistically significant.

تعد المبيدات الكلورينية العضوية من أكثر الملوثات توافرا في البيئة نظرا لثباتها العالي، وانتقالها خلال سلسلة الغذاء، وتراكمها في أنسجة الكائنات الحية. ونظرا لعدم وجود بيانات عن مستويات متبقيات هذه المبيدات، وكذلك العناصر الثقيلة في الخضروات، والفاكهة والموجودة في السوق الليبي بالمنطقة الشرقية، ومعرفة مدي خطورتها علي صحة المستهلك، وذلك بمقارنتها بالحدود القصوى المسموح بها عالمياً، لذلك تم إجراء تحليل لمتبقيات هذه المبيدات مثل(BETA HCH - gamma HCH - DELTA HCH – Chlordene- Dicofol- Endosulfan - P,P´ –DDE - P´P´- DDD - Endrin -Heptachlor) والمعادن الثقيلة على بعض أنواع الخضر، والفاكهة في مدن: درنة، البيضاء، والمرج، حيث أوضحت النتائج وجود فروق معنوية بين العينات المجمعة خلال الفصول المختلفة من السنة، حيث كانت عينات فصل الربيع أكثر العينات تلوثاً بمتبقيات المبيدات علي الخضروات، يليها الخريف، ثم الصيف، كما أوضحت النتائج أن الخضروات، والفاكهة بمنطقه درنة أكثر تلوثاً بمتبقيات المبيدات الكلورينية، يليها البيضاء، ثم المرج ، وعلي الجانب الآخر بالنسبة للمعادن الثقيلة كان الطماطم أكثرها تلوثا بمعدن الرصاص، والتي كانت تختلف عن الخيار، والفلفل، والسلاطة أما محصول الكوسة فكان أكثر الخضروات تلوثاً بعنصر الزنك، وأقل المحاصيل تلوثاً بالرصاص، وبمقارنة مستويات التلوث بالحدود القصوى المسموح بها عالمياً لم تظهر جميع الخضروات، والفاكهة المختبرة احتواءها على كميات أعلى من الحد المسموح به عالمياً في جميع المناطق، و جميع المواسم، ماعدا مبيد الدايكوفول، والكلوردان ,والهبتاكلور فقد وجدت بتركيزات أعلى من الحدود المسموح بها على بعض أنواع الخضروات مثل: الطماطم، والكوسة.
Post-Fire Vegetation Recovery in Elwasita Area of Al-Jabal Al-Akhdar-Libya - Based on Remote Sensing Information
Authors: Masoud Moussa
Published: December 2021

Satellite-based remote sensing technologies and Geographical Information Systems (GIS) present operable and cost-effective solutions for mapping fires and observing post-fire regeneration. Elwasita wildfire, which occurred during April and May in 2013 in Libya, was selected as a study site. This study aims to monitor vegetation recovery and investigate the relationship between vegetation recovery and topographic factors by using multi-temporal spectral indices together with topographical factors. Landsat 8 (OLI and TIRS) images from different data were obtained which were for four years; April 2013, June 2014, July 2015, and July 2016, to assess the related fire severity using the widely-used Normalized Burn Ratio (NBR).  Normalized difference Vegetation Index (NDVI) was used to determine vegetation regeneration dynamics for four consecutive years. Also, the state of damage, vegetation recovery and, damage dimensions about the burned area were capable of being effectively detected using the result of supervised classification of Landsat satellite images. In addition, aspect, slope, and altitude images derived from Digital Elevation Model (DEM) were used to determine the fire severity of the study area. The results have found that it could be possible to figure out the degree of vegetation recovery by calculating the NDVI and NBR using Landsat 8 OLI and TIRS images. Analysis showed that it mainly oriented towards the northwest (47%), north (29%), and northeast (12%). The statistical analysis showed that fire was concentrated on the incline by 76%, and the most affected areas are those between 200 m-450 m above sea level, with a percentage of 80%. It is expected that the information can be acquired by various satellite data and digital forests. This study serves as a window to an understanding of the process of fire severity and vegetation recovery that is vital in wildfire management systems.

Nanotechnology presents a tremendous opportunity to boost the field of wood preservation through implementing modern and unique metal biocides with improved properties. Nano form of Copper oxide, Zinc oxide and Copper sulphate were made by mechanical milling in the high energy planetary ball mill with 450 rpm for 12 hours. Among the three tested nanobiocides Copper sulphate at 0.5% concentration provided protection to the plywood against wood destroying organisms without sacrificing the bond quality of plywood. This is the first report to develop and test the efficacy of nanobiocide against wood destroying organism in India.
Effect of Altitude and Age of Chir Pine Stands on Litter Production in Mid Hills of Himachal Pradesh
Authors: Sharma J. , Sharma Sandeep
Published: December 2021

The litterfall under different aged (sapling, pole and mature) Chir pine stands were studied at two sites viz. Nauni and Moti Kona (Kasauli) having altitudes 1250-1275m and 1720-1745m amsl., respectively in the mid hills of Himachal Pradesh throughout the year. The litter comprised of needles, twigs / branch and bark under sapling and pole stands of Chir pine whereas cones were also the part of the total litter production under mature stands at both sites. The litterfall was maximum under mature stands followed by pole and sapling stands at Site-I whereas it was maximum under pole stand followed by mature and sapling stands at Site-II. The needles had the maximum share (93 to 99%) in the total litter under all the Chir pine stands. The average annual litter production under sapling,pole and mature stands was 64.68, 73.49 and 102.01 q/ha, respectively at Site-I whereas at Site-II, it was 33.34, 55.20 and 37.84 q/ha, respectively. The needle fall was maximum in summer months i.e. April and May under all the Chir pine stands at both the sites and it was about 60 to 70 per cent of the total litterfall of the year. The information generated from the present study may be beneficial for devising management strategies for Chir pine needle litter and can also help in making the strategies for fire control in Chir pine forests of mid hills of Himalayas.

Model-Image Registration of Parametric Shape Models: Fitting a Shell to the Cochlea
Authors: Baker Gavin , Barnes Nick
Published: January 2022

Mathematical models are often used to describe natural phenomena, organisms and anatomy. This paper presents a Model-Image Registration framework that can be used to evaluate models of anatomical shape. An optimisation process is applied to the model parameters to fit the model to an organ of interest in a volumetric image. The fit is obtained by maximising a metric that measures how closely the model surface atches the image edge features, according to gradient magnitude and orientation with respect to the surface normal. The system was tested using a spiral shell model, with generated data as ground truth, and also with CT scans of the temporal bone. The parameters converge to within a close tolerance after a few hundred iterations on the test data, and show promising results on registering with the clinical data.

Earthquake source parameter estimation using synthetic waveform modelling
Authors: DATTATRAYAM R.S.
Published: December 2021

Fault plane solutions and focal depths for three crustal events occurring in the Himalayan collision zone have been obtained using synthetic waveform modelling. Two crustal events with their epicenters in the Tibetan plateau show large component of normal faulting with east-west trading T-axes. The third event with It’s epicenter north of Main Boundary Thrust (MBT) shows reverse faulting with the nodal planes paralleling the local structural trend. All the three crustal events studied have occurred at shallow focal depths of less than 15 km. The Inferred source parameters of these events are discussed In the light of active tectonics of the region.

Authors: RAO P. RAJESH , SAXENA R. C. , BANERJEE S. K.
Published: December 2021

Consequent to installation of 10 cyclone detection radars and availability of INSAT observations availability of fixes* of cyclones by two or more radars and satellite has become a common feature during tracking of cyclones. Generally these fixes differ from each other to some extent. The paper presents a study of tracks of four cyclones in Bay of Bengal as determined by coastal radars and satellite. It is seen that satellite fix is generally closer to coast as compared to radar fix. Amongst radar fixes, the fix of radar closest to the storm may be considered as best fix of the system.

Published: December 2021

A methodology has been presented to compute basal crop coefficient from soil moisture and heat unit accumulations, for wheat in the humid region of northeast India. In developing the method data from 1976-77 to 1981-82 crop seasons for the Sonalika variety of wheat from germination to maturity have been used and tested on independent data set for 1982-83 and 1985-86 crop seasons.

 

Milk stage to physiological maturity stage is found to use maximum fraction of heat unit totals. The largest value of basal crop coefficient is about I 5 occurring during milk stage of the crop growth. Very high correlation is noticed between the actual ET and those computed from the model.

Authors: SINGAL S. P. , GERA B. S. , OJHA V. K.
Published: December 2021

A monostatic sodar was set up at Jodhpur, the extreme end of the monsoon trot*, to study the thermal boundary layer up to a height of 700 m. This effort was a part of the co-ordinated multi institutional project to study the monsoon dynamics. The usual structures of thermal plumes, ground based stable layers, elevated/multi- layers with or without undulations and dot echoes were seen. However, erosion of the inversion layer normally observed in the morning in the form of a rising layer over land areas was absent all through the period of observation from June to August 1990. In the paper, a study of the observed data in relation to the rainfall activity has been made. A preliminary examination shows that sodar structures may provide addi• tional information, not available normally through the conventional meteorological tools.

Published: December 2021

Variations of radio refractive index (RRI) in the lower troposphere over Bombay and Thiru-vananthapuram have been studied for the months from April to July for the years 1979 to 1987. It is seen that in most of the years, the radio refractive index at 900 hPa over Bombay increased significantly prior to onset of monsoon over Kerala (Thiruvananthapuram) and well in advance of the arrival monsoon over Bom-bay. Variation of RRI at 850 hPa level over Bombay also shows significant increase a few days later than at 900 liPa level. At higher levels no such significant changes are observed. The KM value over Thinivanantha-purain at 900 hPa or at 850 hPa does not show significant rise from pre-monsoon to monsoon months. The results show a slight decreasing trend during the same period.

Authors: DATTATRAYAM R.S. , SENO TETSOZO
Published: December 2021

Slip vectors of thirty-nine thrust events occurring along the Himalayan collision zone have been compared with the velocity vectors between the Indian-Eurasian plates derived from the RM 2 and NUVEL 1 models, The observed deviations of the slip vector from the velocity vector have been interpreted in terms of a simple kinematic model according to which the eastern and western blocks of south Tibet are separating from each other, From the model it is estimated that the western and eastern blocks of Tibet are moving at the rate of 3.6 cm/year westwards at 76°Eand 2.6 cm/year eastwards at 94°E with respect to Eurasia respectively, resulting in an east-west extension, projected to the trend at 85°E, at the rate of 5, 5 cm/year. This would correspond to a strain rate of about 6.9 x 10-8year in central Tibetan region.

Published: December 2021

Meteorological data (1971-2000) for twenty seven (27) well distributed locations in India, have been utilized to compute average monthly rainfall (RF) and potential evapotranspiration (PET). In the present study, potential evapotranspiration (PET) has been calculated by using FAO recommended Penman-Monteith equation. An attempt has been made to identify the months of water deficit / surplus and these have been discussed in relation to crop planning for both seasons Monsoon or Kharif (June to September) and Rabi (October to February).In northwest, west and central zone, water deficit is observed at several stations in Kharif and all stations in Rabi. The average RF/PET ratio in this zone is 0.53 indicating that except in Pantnagar and Adhartal (0.94), crop selection and planning do not favour crops requiring more water. During Kharif season RF/PET ratio of several stations, except Hissar and Jodhpur, is more than 1, suggesting successful cropping with rainfall. In east and northeast zone, water surplus is observed at all the stations in Kharif. Water deficit in Rabi occurred at most of the places during December, January and February. RF/PET ratio during Kharif season ranges between 1.44 and 5.93 suggesting none of the stations undergo water deficit during the crop growing period. For the stations selected in south zone, water deficit in Kharif occurred at many places in the months of June, July and August. Water deficit in Rabi occurred at many places during January and February. During Kharif RF/PET ratio is less than 1 except for Rajamundry and Pattambi. This emphasizes the need for proper crop selection for successful cropping with limited moisture.
Correlation between glycated hemoglobin HbA1c and serum lipid profile in patients with type 2 diabetes
Authors: Alboueishi Asmaa
Published: December 2021

Background: Hyperlipidemia is a common risk factor for diabetes that leads to cardiovascular disease, one of the causes of death of diabetic patients. Theaimof this study was to investigate the association between HbA1c levels and serum lipids in Libyan patients withtype 2 diabetes. Material and methods: The study was conducted in 2019 on 325 patients (174 males, 151 females) with type 2 diabetes referred to a private clinical laboratory in Tripoli, Libya. Blood samples were collected for measurement of HbA1c, fasting blood glucose and serum lipid concentrations. Diabetes was defined according to the American Diabetes Association criteria.The data were analyzed using an independent t-test and Pearson’scorrelation test.Results: The ages of the patients ranged from 40 to 83 years, with a mean of 51.52 ± 14.32 years SD. No significant correlation between HbA1c and age was noted (r=0.011, p=0.063). There was a significant positive correlation betweenHbA1c level and fasting blood glucose (r =0.641, p=0.000), low-density lipoprotein (r = 0.240, p = 0.000), total cholesterol (r = 0.223, p = 0.000) and triglycerides(r=0.140,p 0.067). The correlation between HbA1c and high-density lipoprotein-C was negative but not significant (r= -0.088, p = 0.123). Conclusion: HbA1c could be used as a predictor of dyslipidemia and thus it may serve as anindicator of the development of cardiovascular disease in patients with type-2 diabetes mellitus.
