Factors Affecting Characteristic Length of the Combustion Chamber of Liquid Propellant Rocket Engines
Authors: Khan Tajwali , Qamar Ihtzaz
Published: February 2020

Optimum characteristic length of the combustion chamber of liquid rocket engine is very important to get higher energy from the liquid propellants. Characteristic length is defined by the time required for complete burning of fuel. Combustion reactions are very fast and combustion is evaporation dependent. This paper proposes fuel droplet evaporation model for liquid propellant rocket engine and discusses the factors which can affect the required size of characteristic length of the combustion chamber based on proposed model. The analysis is performed for low temperature combustion chamber. A computer code based on proposed model is generated, which solve analytical equations to calculate combustion chamber characteristic length under various input conditions. The analysis shows that characteristic length is affected by combustion chamber temperature, pressure, fuel droplet diameter, chamber diameter, mass flow rate of propellants and relative velocity of the droplet in the combustion chamber.

This study deals with the evaluation of soil engineering characteristic along the proposed route of Jalalpur irrigation project. The proposed JIP (Jalalpur Irrigation Project) is located along the right bank of Jhelum River in Tehsil PDK (Pind Dadan Khan) and Tehsil Khushab of District Khushab. JIP is funded by ADB (Asian Development Bank). The JIP will enhance crop production in Tehsil PDKand Khushab. Farmers will be benefited through JIP as they will get regular supply of water through canal. It will also create job opportunities for local people and will lead to the prosperity of the Project area. Detailed soil investigation along proposed route was carried out by M/S GEO BAND. Straight rotary method of drilling was used. The recovered soil samples and water samples were tested in laboratories. The detailed engineering analysis was performed and soil parameters along with bearing capacities are suggested. Results have indicated variations in SPT values along the proposed route. The top layer of soil along proposed route is mostly Silty Clay with variation along the depth. The proposed bearing capacity for shallow foundation is 1.25 ton/ft2 (120 kN/m2) at depth of 5ft (1.5 m) beneath footing, and for bored piles having diameter of 2.5 ft (0.76 m) at a depth of 50 ft (15 m) is recommended as 70 ton (685 kN).

Published: February 2020

From last epoch till to date, AISI 4340 and AISI 4140 have been widely used in different engineering applications. These applications include bolt, screws, gears, drive shafts, crane shaft and piston rods for engines due to its upright mechanical properties, cost-effective and easily available in market. In present work, deep cryogenic treatment effect on the mechanical properties of AISI 4340 and AISI 4140 have been studied. Present work was carried out at laboratory scale and can be extended for mass production. Our work is simple, straight forward safe and economical. In our work, samples were heat treated in simple muffle furnace and followed by cryogenic treatment in liquid nitrogen. Before cryogenic treatment, all samples were normalized at 860°C to obtain homogenized micro structure. Samples were also compared conventionally heat treatment with quenched in oil quenchant. Experimental results showed that after cryogenic treatment with tempering treatment, one could easily increase the tensile strength, impact toughness and hardness. Advanced optical microscopy (IMM 901) and SEM (Scanning Electron Microscopy), FIT Quanta 200 methods have also been deployed to reveal and interpret the internal structure of samples. It was found from micro structure that cryogenic treated sample increases the impact strength, hardness and tensile strength as compared conventional heat treated quenching approaches.
Heritage at Stake: Discourse Concerning the Causes of Damages Occurred to the Historic Hostel Structures Built in British Era in Karachi
Authors: Soomro Tania Ali , Soomro Mohsin Ali , Kanwal Hummaira
Published: February 2020

Karachi being the first born city of the colonial architecture in Sindh Pakistan has the honor of housing very important and diverse ornamental architectural master pieces. Along with the commercial nucleus; Karachi emerged as a regional educational hub after the partition of the Indian subcontinent in 1947 with several hostel structures and studio apartments. These structures are among the better examples of the pre-colonial and post-colonial architectural influence in the region. Few of them (still surviving) are incorporated in the national list of protected heritage under Sindh Cultural Heritage Preservation Act 1994. This research paper is focused on “the lost importance of the three different hostel (boys’ hostels only) premises in the historic core of the city of Karachi”. Despite possessing similar functions in the past and having the same status of the declared protected heritage at present, each of them has different use and conservation status at present. None of the buildings have endured the original function. This research focuses the reasons of the non-continuation of the original function and the impairments caused to the buildings due to this reason. Methodology followed for the research includes analysis of available archives, physical observation, photographic documentation and interviews with the local inhabitants of the neighborhood. The results and the findings of this research portray that eroding hostel culture has subjected those structures to slow and painful death of their original purpose. These buildings, once popular in the area, are now fading fast and perhaps will cease to exist in the near future unless the immediate precautionary measures are taken. The main conclusion drawn in this paper is that “it is important to preserve those historic premises as they are of significant historic character that remained associated with a number of key political and social personalities of the region. Moreover, they play a vital role in the general architectural value of the region”.

Published: February 2020

In this study, the structural integrity of liquid metal fast reactor fuel
assembly has been established for different parameters considering the
optimum fuel design. Analytical calculation of added mass effect due to lead
bismuth eutectic and verification through previously presented theories, has
been established. The integrity of the hexagonal wrapper of fuel assembly
has been guaranteed over the entire operating temperature range. Effect of
temperature on the density of lead bismuth eutectic, the subsequent
change in added mass of lead bismuth eutectic, the effect on natural
frequencies and effect on stresses on wrapper, has been studied in detail. A
simple empirical relationship is presented for estimation of added mass
effect for lead bismuth eutectic type fast reactors for any desired
temperature. An approach for assessment of fast reactor fuel assembly
performance has been outlined and calculated results are presented. Nuclear
seismic rules require that systems and components which are important to
safety, shall be capable of bearing earthquake effects and their integrity
and functionality should be guaranteed. Mode shapes, natural frequencies,
stresses on wrapper and seismic aspect has also been considered using
ANSYS. Modal analysis has been compared in vacuum and lead bismuth eutectic

Authors: Chen Xiaohua , Wang Zhanshan , Yang Yan , Zhang Guangcai
Published: February 2020

The ring hoop tension test is an important test method for evaluating the deformation performance of tube. The mechanical model of the hoop tension test is established under the condition that deformation caused by the friction of the die is unequal. The mechanical model is input into the finite element model and compared with the tube uniaxial hoop tensile test. The mechanical model simulation obtained by this method has a better coincidence with the experimental data. Through further analysis of the bulging test of the process, it is proved that the established hoop mechanical model can accurately reflect the plasticity variation characteristics of the tube deformation.
Image encryption algorithm for torsional components of generator based on compound chaotic model
Authors: Shao Yu
Published: February 2020

In order to solve the problem that the image encryption algorithm cannot eliminate the strong correlation between adjacent pixels in the image, with poor ability to resist attack and low efficiency, an Image encryption algorithm for torsional components of generators based on complex chaotic model is proposed. Extracting the RGB torsional vibration component of the image for discrete cosine transform transformation, it is then rotated and fused to complete the initial encryption of the image information. In order to further enhance the security of image information, 2-D discrete cosine transform and 2-D compressed sensing measurement are applied to the initial encrypted image information. The real number matrix of measurement is merged into the complex value matrix, and the adaptive random phase coding is applied. The image information complex chaotic encryption model is constructed according to the coding result, so as to eliminate the strong correlation between the adjacent pixels. Particle swarm optimization is used to co-ordinate and optimize the parameters of the compound chaotic encryption model to improve the encryption performance of the model. Experimental results show that the pixel has low correlation, high security and strong ability to resist attacks after encrypting with this algorithm.

Published: February 2020

Objectives

To assess the effects of piezocision on the rate of mandibular second molar protraction.

Materials and Methods

Thirty-one subjects (average age: 22.26 ± 5.63 years) who presented with at least one extracted mandibular first molar were selected to participate in the study. The subjects were subdivided into one of two groups, 22 molars each: group 1, where piezocision was performed immediately before molar protraction and group 2, where molar protraction was performed with no piezocision. Piezocision was performed by making two vertical incisions mesial and distal to the extraction space, and bone cuts were done with a length up to the mucogingival line at a depth of 3 mm. The rate of second molar protraction, duration of space closure, and level of interleukin-1-β (IL-1β) in gingival crevicular fluid (GCF) during the first month of space closure were recorded.

Results

During the first 2 months after surgery, the rates of second molar protraction were 1.26 ± 0.12 mm/month and 0.68 ± 0.19 mm/month in the piezocision and no piezocision groups, respectively (P < .001). Duration of lower first molar space closure was 9.61 ± 0.98 months in the piezocision group and 10.87 ± 1.52 months in the no piezocision group (P < .01). The level of IL-1β in GCF was higher in the piezocision group compared to the no piezocision group, up to 1 week after surgery (P = .02).

Conclusions

Although piezocision doubled the rate of second molar protraction during the first 2 months after surgery, overall second molar protraction was increased by only 1 month.

Authors: Tan Ayten , Çokakoğlu Serpil
Published: February 2020

Objectives

To evaluate the effects of adhesive precoated (APC) flash-free brackets on enamel demineralization and periodontal status in patients during fixed orthodontic treatment.

Materials and Methods

Thirty patients, age 12 to 18 years, who had Angle Class I or Class II malocclusion with mild to moderate crowding in the permanent dentition were selected for this study. APC flash-free and conventional ceramic brackets were bonded for a split-mouth study design. The quadrant allocation was randomized. Demineralization records were obtained immediately after bonding (T0), 1 month after bonding (T1), and 6 months after bonding (T2). Clinical periodontal measurements, including gingival index, plaque index, and bleeding upon probing, were obtained before bonding (T0) and at the same time points (T1 and T2). Data were analyzed using Mann-Whitney U and Friedman tests to compare parameters between groups and times.

Results

Demineralization values decreased on most sides of the brackets for both groups between T0 and T1. In the conventional group, there was significantly higher demineralization on more sides compared with flash-free brackets between T1 and T2. With one exception, the decreased values were found in the incisal/occlusal sides of all brackets at T2. All periodontal parameters showed significant increases after 6 months of treatment in both groups. Intergroup comparison showed no significant differences in demineralization or periodontal measurements at any of the time points.

Conclusions

The effects of APC flash-free and conventional brackets on enamel demineralization and periodontal health did not differ from each other.

Published: February 2020

Mantle vegetation includes plant communities dominated mostly by shrubs and occurs in habitats where the typical tree layers meet difficulties to evolve. This study was conducted in three areas of Bulgaria – Western Balkan Range, Western Sredna Gora Mt. and the Fore-Balkan. Numerical classification and ordination were performed by PC-ORD and JUICE software packages. Diagnostic species were determined by calculating the Phi-coefficient. Two associations and one plant community of the Berberidion alliance were recognized – Corno-Ligustretum Horvat ex Trinajstić ---amp--- Z. Pavletić 1991, Pruno spinosae-Ligustretum vulgaris Tüxen 1952 and Elytrigia repens-Crataegus monogyna community. The latter considered as a successional stage of shrub encroachment into the grasslands. Its species composition is very close to that of the ass. Corno-Ligustretum. The species composition of ass. Pruno-Ligustretum represents a mixture of species characteristic for dry and mesic grasslands, fringe and forest vegetation. The Crataego-Prunetea class is still poorly studied in Bulgaria and much more data from all regions in the country have to be collected.

Vegetation succession in extensive abandoned tall-trunk cherry orchards: a case study on Kaňk Mountain near Kutná Hora (Czech Republic)
Authors: Šantrůčková Markéta , Dostálek Jiří , Frantík Tomáš
Published: February 2020

Extensive tall-trunk orchards, an important element of the central European landscape since the Middle Ages, conserve potential for the future regarding their biodiversity, land use policy and agricultural value. For these reasons, extensive tall-trunk orchards are interesting with regard to nature conservation. Once the management of these low-productivity vegetation sites ceases, the habitat is threatened by successive overgrowth by shrub vegetation. Taking abandoned tall-trunk cherry orchards with dry/mesophilous grassland undergrowth in the locality of Kaňk as an example, the degree of colonization of orchards by woody species and differences in the structure of vegetation cover in different periods after abandonment were monitored. The results showed that the cover of cherry trees in orchards abandoned before 1990 was approximately 30% lower than in orchards abandoned after 2000. The cover of the herb layer in orchards abandoned before 1990 was approximately 60% lower than in orchards abandoned after 2000. The species diversity of orchards abandoned before 1990 was statistically significantly lower than that of orchards abandoned after 2000. The total cover of all species in habitat in areas of medieval ore extraction was approximately 50% lower than that in land originally used for farming.

It argues that, despite some views presented in the doctrine of international law, claims of a quasi-customary international law are without foundation in the current state of international law. The paper is divided into three parts. The first part presents the views of legal doctrine concerning the customary law as contributed/created by non-state actors. The second section argues that ANSAs do not form practice and opinio juris which would allow them to create their ‘own’ customary law. The final part presents the possible challenges and consequences of including ANSAs in the process of formation of customary international law as created by States. In summary the conclusions posit that it could be potentially very harmful for international humanitarian law and the protection of human rights.

Introduction: Cystic congenital malformations of the seminal vesicle are unusual. More than half of them are associated with ipsilateral renal agenesis. This disease was first described by Zinner in 1914, and since then, more than 200 cases have been reported. Most of the patients with this congenital disease present few symptoms until the middle-age.

Case presentation: A 61-year-old male was referred to the Urology Clinic with intermittent pain and sensibility in his lower left abdomen in the last 12 months accompanied by intermittent bowel obstruction. The digital rectal examination could not assess the prostate due to a rectal stenosis. On computed tomography and magnetic resonance imaging (MRI) a cystic tumor with close relations with the bladder wall and prostate, associated with left kidney agenesis was identified. The cystic tumor was surgically removed. The histopathological examination of the tumor revealed a multilocular seminal vesicle cyst, with a muscular wall.

Conclusions: Seminal vesicle cysts combined with ipsilateral renal agenesis are rare urological anomalies. Imaging allows a comprehensive investigation of renal and seminal vesicle anomalies. MRI seems to better visualize cysts and differentiate them from ureteroceles, while the histopathological examination contributes to a correct diagnosis. A multidisciplinary team (urologists, radiologists, and morphologists) is necessary for the proper diagnosis of Zinner’s syndrome.
