Predisposing factors associated with teenage pregnancy in Lake Victoria Islands and Mountain districts of Uganda

Introduction There is a high teenage pregnancy rate in Lake Victoria Island and Mountain districts of Uganda. Teenage pregnancy leads to unsafe abortions, infant and maternal mortality, high rate of unemployment, and school drop-outs. This paper aims at establishing the factors influencing teenage pregnancy in Uganda Lake Victoria Island shoreline area and mountain districts. Methods The analysis focused on 405 girls aged 15–19 years, generated from the 2016 Uganda demographic and Health Survey. The chi-square test statistic was used to establish factors associated with teenage pregnancy. Unadjusted and adjusted binary logistic regression analysis were conducted on explanatory variables to establish the predictors of teenage pregnancy in the Lake Victoria Island districts and the mountain districts. Statistical significance was considered at 5% level. Results The findings show that teenage pregnancy rate was at 48% in the Lake Victoria Island districts and at 24% in the mountain districts. Predictors of teenage pregnancy include; aged 18 – 19 years (AOR=4.78, p=0.000, 95% CI 2.85 – 8.01), being in a female-headed household (AOR=0.46, p=0.004, 95% CI 0.25 – 0.85), being in a “working” occupation (AOR=2.22, p=0.005, 95% CI 1.28 – 3.85), belonging to the “rich” quintile (AOR=0.54, p=0.03, 95% CI 0.31 – 0.97) and knowledge of any family planning methods (AOR=18.37, p=0.008, 95% CI=2.17 – 155.5). , Conclusion The factors associated with high teenage pregnancy in the Uganda Lake Victoria Island shoreline area and mountain districts include; age, sex of household head, occupation (not working), socio-economic status and knowledge of family planning methods. There is need for programs that promote contraceptive use among teenagers and household wealth creation projects, with special attention to dwellers in remote and hard-to-reach areas of the country.
Termite Mound Clay as Material for Grain Silo Construction

Silos are the most appropriate structures for the bulk storage of grains. Their performances are greatly influenced by the materials of construction and the climatic environment where they are used. Under the warm and humid climate prevalent in Nigeria, metal silos which are the predominant structures used for grain storage experience moisture condensation, resulting in grain deterioration. There is therefore the need to source for construction materials that will eliminate moisture condensation, durable, easy to construct, cheap and readily available to farmers. Termite mound clay was identified as a potential material. A 5.6m3 silo was designed and the prototype constructed with treated termite mound clay bricks. Temperatures were measured inside and outside the silo and the quality of grain stored in the silo was monitored over a period of two months. Viability tests of stored grain were also undertaken. Minimum and maximum temperatures outside the silo were 21oC and 36oC as against 20oC and 30oC inside the silo. Temperature fluctuation within the silo was 9.5 oC compared with 10.3 oC outside. Grain quality was maintained during the storage period, the viability before and after storage were 88% and 84% respectively. The treated termite mound clay silo demonstrated great potential for reducing temperature fluctuations and maintaining grain quality in storage. It is recommended that the simulation of moisture content, relative humidity and temperature profiles under full load should be undertaken. A comparative evaluation of the silo performance with those of other materials of silos construction should also be undertaken.

Pulse propagation along conductors in low-density, cold plasmas as applied to electrodynamic tethers in the ionosphere

PULSE PROPAGATION ALONG CONDUCTORS IN LOW–DENSITY, COLD PLASMAS AS APPLIED TO ELECTRODYNAMIC TETHERS IN THE IONOSPHERE by Sven Gunnar Bilen Chairperson: Brian E. Gilchrist This research characterizes the general propagation behavior of high–voltage elec- tromagnetic pulses along conductors in low–density, cold plasmas. As a specific ap- plication, this characterization uses electrodynamic tethers in the ionosphere. Elec- tromagnetic pulses are produced along the tether–plasma system as it transitions from open– to closed–circuited states and as it is driven by radio–frequency voltage sources. These perturbations take a finite amount of time to propagate along the tether and, as they do so, they affect the surrounding ionospheric plasma. This in- teraction in turn affects the tether’s transmission–line characteristics. The dynamic evolution of the sheath is examined as the pulse front travels past a given section of tether and disturbs the local sheath. Present tether transmission–line models assume, as a first–order approximation, that the plasma–sheathed tether can be modeled as a simple rigid coaxial transmis- sion line. This has proven acceptable for tethers with low induced or driven voltages. An improved model is needed, however, when steady–state plasma–sheath dynamics cannot be assumed, such as for longer deployed tether lengths, which have higher induced emf, or higher driven voltages. A dynamic circuit model of the plasma–sheathed tether is developed with know- ledge gained from theoretical analyses, experimental results, and particle–in–cell computer simulations. Using this dynamic–sheath model as their basis, lumped– element transmission–line parameters for capacitance and inductance per unit length are derived for the plasma–immersed tether where it was found that capacitance is a function of voltage but inductance is approximately constant. These parameters are included with per–unit–length resistance and induced–emf elements to form the complete lumped–parameter model. The tether circuit model is implemented in the SPICE circuit simulation program. This implementation allows examination of the tether’s transmission–line characteristics as well as pulse propagation and mor- phology. Previously developed models of satellite and Orbiter interactions with the plasma based on Tethered Satellite System mission data can be used with this circuit model as the endpoints of the complete electrodynamic–tether system.
Evaluation of indoor environment conditions in offices located in buildings with large glazed areas

Abstract The field study was carried out during the heating season in two Lithuanian office buildings with large glazed areas. The methodology was prepared for evaluating indoor microclimate parameters while using objective and subjective evaluation. The results show that the average temperature in all tested offices was in the range of optimal zones, but in some offices the average temperature was not in compliance with the recommended temperature for offices. During the subjective evaluation, respondents working in these offices identified complains because of too high temperatures, stuffy air and irritation in eyes. The average relative humidity measured in all tested offices was not in compliance with the optimal requirements. Such SBS symptoms as irritation in eyes, cough and dry skin of the hands were identified as the most frequent symptoms in the second tested building. Main indoor microclimate problems arising in buildings with large glazed areas were related to overheating indoor spaces because .
Tunable microwave and millimetre-wave metamaterial structures and applications

Novel designs of metamaterial structures as well as novel techniques and configurations for tuning metamaterials are presented in this PhD thesis. The proposed tuning techniques overcome the challenges that exist in other tuning techniques available thus far. Moreover, possible applications of tunable metamaterials in communication systems are proposed. Initially, tunable Electromagnetic Band-Gap (EBG) structures are proposed for low frequencies operation (3GHz to 6GHz) employing a novel biasing technique for varactor diodes. Subsequently, the proposed tunable EBG structures are applied to closely spaced antennas, achieving isolation enhancement for MIMO systems. Moreover, a new technique of tuning High Impedance Surface (HIS) structures is presented, with low-loss performance and no parasitic effects, based on employing two types of piezoelectric actuators, each type being suitable to a different frequency band. Particularly, bender piezoelectric actuators are used for configurations operating at low mm-wave frequencies (~15GHz) and stack multilayer actuators for operation at higher mm-wave frequencies (60GHz) where achieving a low loss performance is even more challenging. Two tunable antenna designs are also proposed incorporating both tunable HIS structures (at 15GHz and 60GHz). Finally, novel configurations of tunable Frequency Selective Surfaces (FSS) are proposed based on the concept of piezoelectric actuators to obtain a tunable response. Again, this is carried out for two operating bands, 15GHz and 60GHz. The particular designs of tunable HIS and FSS, are directly scalable to even higher frequencies (THz), offering a promising solution at this band.
A Panoramic Study of the Morphology of Mandibular Condyle in a Sample of Population from Basrah City

A panoramic study of the morphology of mandibular condyle in a sample of population from Basrah city. Int. J. Morphol. , 38(6) :1707-1712, 20202. SUMMARY: The study aims to evaluate the morphological variation of mandibular condyle This analysis was composed of 450 digital orthopantomograms taken for routine investigation to assess the morphology of 900 condylar heads. Condylar morphology was classified into four types (oval, bird beak, diamond and crooked finger). Most common occurring shape were evaluated, symmetry of condylar shape and most common combinations of the condylar shapes present in population were assessed. Out of 900 mandibular condyle, type 1(oval) of condyle was the most commonly appearing shape (56 %), followed by type 3 (diamond), type 2(bird beak) and finally type 4 (crooked finger). Symmetry was seen in 74.2 % of the total sample with the oval-oval was the most commonly occurring. Routine use of orthopantomography can assist dentist in assessment of condylar morphology alterations. Oval shape was the most common in all age groups in males and females. More studies on Iraqi population evaluating mandibular condyle are needed to provide standardized values for mandibular anatomical parts.
Design of Morphing Leading and Trailing Edge Surfaces for Camber and Twist Control

The application of morphing structures in conventional aircraft is a method to improve aircraft performance by both reducing the total fuel consumption for a given mission profile, or by allowing one type of aircraft to perform a wider range of missions. The current generation of aircraft does not widely use morphing technology to optimize flight performance, instead specialized types are developed specifically for one target mission. This report shows the process of integrating a span, twist and camber morphing system into an unmanned testbed as part of the CHANGE project. First several configuration concepts are proposed and evaluated which allow the twist/camber system to be developed independently from the span extension system. This results in a wing design where the leading and trailing edges contain the morphing mechanism, while the central wing box provides space for the span extension mechanism. The application of morphing surfaces is also limited to the inboard wing sections, as the internal volume of the tips is dedicated entirely to housing the extending wing sections. Several options for the morphing mechanisms are discussed and traded off, though eventually a novel system is developed based on open section torsion for twist control and sheet bending for camber control. The magnitude of the deformation required to meet pre-determined target shapes is calculated via numerical simulation, as are the forces which are imparted on the structure and the actuators by elastic loads. Aerodynamic loads are also calculated. Finally, a detail design is proposed for both the leading and trailing edge mechanisms which satisfies the required camber and twist ranges while taking into consideration the maintainability of the structure and availability of parts. The design consists of a GFRP skin of which the top surface acts as a compliant hinge. The lower surface of the skin is supported and constrained by an internal mechanism, while actuation is provided by electric servos. The symmetry of the final design allows for left to right interchangeability of the entire control surface.
First CFOA-based explicit-current-output quadrature sinusoidal oscillators using grounded capacitors

To date, no current-feedback operational amplifier (CFOA)-based sinusoidal oscillator has been reported which provides all the following features simultaneously: (i) current-mode quadrature sinusoidal oscillator providing two explicit-current-outputs (ECOs) from high output impedance terminals, (ii) employing no more than three CFOA ICs and six passive components, which include two grounded capacitors, (iii) offers independent tuning of the condition of oscillation (CO) via a resistor and (iv) provides tunability of the ratio of amplitudes of the generated quadrature ECOs via a separate resistor. To the best of authors' knowledge, this article reports first CFOA-based QOs in current-mode (i.e. providing two ECO signals). Experimental results using AD844 CFOA ICs from Analog Devices have been included to verify the workability of the proposed oscillator circuits. An example automatic gain control (AGC) loop to regulate the oscillation amplitude and control the THD has also been used and verified using SPICE simulations using the AD844 macro-model.
Proposed Model of Attitude Toward Advertising Through Sport

When attending or watching sporting events, amateur or professional, people are exposed to a variety of advertising. People form attitudes toward advertising that influence their decision making processes to purchase a particular advertiser’s product. The current study examines a new construct, attitude toward advertising through sport, derived from Pollay and Mittal’s (1993) model of attitude toward advertising in general. Through an exploratory investigation a scale to measure attitude toward advertising through sport is tested. The preliminary results from several stages provide support for the conceptualization and measurement of the belief dimensions proposed to influence attitudes toward advertising through sport. The assessments of the structural equation model reveal that respondents’ perceived beliefs of product information and hedonism/pleasure about advertising through sport play significant roles in accounting for their overall attitude toward advertising through sport.
Inland Container Logistics and Interports. Goals and Features of an Ongoing Applied Research

In a container transportation and logistics network, we define an interport as a common user hub facility located in the hinterland of one or several seaports, and where different services are available to carriers and shippers, such as: container stuffing and unstuffing, rail-road trans-shipping, temporary storage of import/export full and empty units, customs clearance and inspection, container tagging and sorting, container and vehicle maintenance and repair, and even the opening, manipulation and processing of the containers' content for later marketing efforts at ultimate destinations. The interport's functions thus range from simple cargo consolidation/deconsolidation and intermodal switching to customs operations and advanced quasi-manufacturing and distribution logistic services (assembly, kitting, packaging, labelling, quality control, reverse logistics, city logistics, etc.). Interports represent an innovation posing challenges and opportunities for many operators involved in freight transport, logistics, manufacturing and trade.In the following sections, after a brief general presentation of some main features of the containerisation and intermodality, we focus on inland container logistics and interports. More specifically, we deal with issues related both to the meaning of the term "interport" and the functions of this new kind of inland freight node with reference to the case of Italy and by considering the recent evolutions in container transportation and logistics networks. Furthermore, we introduce some preliminary topics related to the interport-seaport system in Campania, a region lying in Southern Italy, by describing some technical and organisational features of the regional rail freight network and in particular of the interport-seaport railway connections. We also illustrate the case of Marcianise in Campania as a relevant example of Italian interport. Finally, we describe the main goals and features of an ongoing research concerning an empirical application of a mathematical programming model to optimize the distribution of container flows through the Campania seaports and interports.
Outcome Comparison of Arthroscopic versus Mini-open Technique for Ankle Arthrodesis

Background Ankle arthrodesis is considered to be the gold standard for the treatment of end-stage ankle diseases. At present, the commonly used methods of ankle arthrodesis include open ankle arthrodesis, arthroscopic ankle arthrodesis and mini-open ankle arthrodesis. The authors analyze and compare the clinical efficacy and related complications of arthroscopic ankle arthrodesis and mini-open ankle arthrodesis in the treatment of end-stage ankle disease. Methods From January 2007 to June 2018, 56 patents with end-stage ankle joint pathology were treated with arthroscopic ankle arthrodesis and mini-open ankle arthrodesis. There were 30 cases in arthroscopy group, including 19 males and 11 females with an average age of 49.6 years old (ranged, 32 to 71); while 26 cases in mini-open group, including 18 males and 8 females with an average age of 48.3 years old (ranged, 43 to 65). The operative time was calculated with use of computerized operative and anesthetic records. The pain visual analogue score (VAS), American Orthopedic Foot ༆ Ankle Society ankle and hind foot score (AOFAS), fusion rate, complications rate, length of hospital stay, operation time, and tourniquet time were compared between the two groups of patients. Results 51 patients were followed up for 15–35 months (mean, 22.5 ± 1.5) months. The bony fusion was achieved in all patients. The average time to fusion was 12.4 weeks (range, 10–16 weeks). The VAS score 3 days post-operation was (6.37 ± 0.69) points in the arthroscopy group and (7.61 ± 1.05) points in the mini-open group, there was significant difference between the two groups (P < 0.05). The VAS score and AOFAS score between the two groups pre- and post-operation have statistically significant differences (P < 0.05). At the last follow-up, VAS score was (1.55 ± 0.57) in the arthroscopy group and (1.43 ± 0.73) in the mini-open group, and there was no significant difference between the two groups (P > 0.05). The AOFAS score was (85.32 ± 2.96) points in the arthroscopy group and (86.72 ± 3.05) points in the mini-open group, and there was no significant difference between the two groups (P > 0.05). Arthroscopic ankle fusion was associated with a shorter tourniquet time and shorter length of hospital stay compared to mini-open ankle fusion (P < 0.05); however, there was no significant difference between two groups in terms of operation time (P > 0.05). Wounds healing was satisfying during the follow-up in the arthroscopy group. But the wounds healing was delayed in two patients of the small incision group. All patients were satisfied with the surgery. Conclusion Arthroscopic ankle arthrodesis and mini-open ankle arthrodesis have satisfactory curative effect and fusion rate. Arthroscopic assisted ankle arthrodesis has more advantages, including small incision, less injury, and low morbidity.
The seasonal cycle and break-up of landfast sea ice along the northwest coast of Kotelny Island, East Siberian Sea

Abstract Arctic landfast sea ice (LFSI) represents an important quasi-stationary coastal zone. Its evolution is determined by the regional climate and bathymetry. This study investigated the seasonal cycle and interannual variations of LFSI along the northwest coast of Kotelny Island. Initial freezing, rapid ice formation, stable and decay stages were identified in the seasonal cycle based on application of the visual inspection approach (VIA) to MODIS/Envisat imagery and results from a thermodynamic snow/ice model. The modeled annual maximum ice thickness in 1995–2014 was 2.02 ± 0.12 m showing a trend of −0.13 m decade−1. Shortened ice season length (−22 d decade−1) from model results associated with substantial spring (2.3°C decade−1) and fall (1.9°C decade−1) warming. LFSI break-up resulted from combined fracturing and melting, and the local spatiotemporal patterns of break-up were associated with the irregular bathymetry. Melting dominated the LFSI break-up in the nearshore sheltered area, and the ice thickness decreased to an average of 0.50 m before the LFSI disappeared. For the LFSI adjacent to drift ice, fracturing was the dominant process and the average ice thickness was 1.56 m at the occurrence of the fracturing. The LFSI stages detected by VIA were supported by the model results.
Demandas em orientação profissional: um estudo exploratório em escolas públicas

Claims in Vocational Guidance: An exploratory study in public schools The article presents a research report aiming at identifying new claims in the vocational guidance field to support the development of new models of actuating, through a public high school students' sample, from the suburban east side of Sao Paulo city. The students' sample was characterized by their family professional history (which determinates their future), and their claim in the work world (expectations and future wishes), using for the data collection questionnaires, some writing about the future, and vocational guidance groups. The main findings have pointed out that the participants expect some guidance related to their immediate insertion in the work market and some help in the planning of their professional life project, signaling the need of new paradigms in the professional guidance field, as opposed to the
