Published: May 2018

Cinco días antes de su muerte el 11 de febrero de 1587, María de Mendoza, VII condesa de Ribadavia, otorgaba en carta de donación a su hija María Sarmiento, duquesa de Sessa, la posesión de todos sus bienes libres no sujetos al mayorazgo familiar. Este artículo pretende reconstruir el relato de esta rica herencia y explicar cómo fue el proceso por el que el palacio familiar en Valladolid fue vaciado por la duquesa.
A One-dimensional Model of Thermo-electroelasticity in Extended Thermodynamics
Authors: Saber Abou-Dina Moustafa , Ahmed F. Ghaleb Ahmed
Published: May 2018

The subject of thermo-electroelasticity involves many complications due to the multiple ways in which the mechanical, thermal and electric fields can interact, some of these involving non-linearities. In extended thermodynamics, an additional difficulty arises due to the requirement of finiteness of the speed of propagation of the thermal disturbances. This implies, as may be observed in the extensive literature on the subject, a re-visiting of the basic postulates of thermodynamics, ultimately leading to the desired generalization. There are only a few nonlinear models dealing with this subject. In order to consider general nonlinear models, it is necessary to study linear ones first, as they represent most of the basic features of the studied phenomena. This is particularly true when the problem is tackled numerically through iteration methods, in which case the starting field equations are linear.Here we study a one-dimensional system of equations of thermo-electroelasticity in extended thermodynamics and in the quasi-electrostatic regime. The nonlinear equations are given for reference only. The mixed character, parabolic-hyperbolic, of the associated linear system is established through the study of the characteristic curves. Two speeds of wave propagation are given in evidence, one for the usual coupled thermoelastic wave, and the other for a second sound. Parabolicity is due to the quasi-static distribution of the electric field. An example concerning the half-space is treated numerically by the Cranck-Nicolson method. The curves presented clearly illustrate the propagation of two types of waves, the usual coupled thermoelastic wave, and a faster wave generated by the second sound. It is hoped that the present study will clarify the basic features of the solution, as a prelude to tackling more sample, nonlinear equations.

Authors: A. Hajji Mohamed , Al-Mdallal Qasem
Published: May 2018

In this paper we consider a system of delay differential equations as a model for the dynamics of tumor-immune system interaction. We carry out a stability analysis of the proposed model. In particular, we show that the system can have up to two steady states: the tumor free steady state, which always exist, and the tumor persistent steady state, which exists only when the relative rate of increase of the tumor cells exceeds the ratio between the natural proliferation rate and the relative death rate of the effector cells. We also determine an upper bound for the delay, such that stability is preserved. Numerical simulations of the system under different parameter values are performed.
Development of a Mathematical Model for Simulation of Macroalgae Farming in the Coastal Areas
Authors: Lababpour Abdolmajid
Published: May 2018

A mathematical model consisting of a system of three coupled partial differential equations (PDEs) was proposed to estimate the concentrations of nitrogen, phosphorous and macroalgae biomass in coastal open waters. However, some simplifying assumptions were used in the model to cope with the complexity of real conditions. For the macroalgae biomass, the system works as a batch mode, while input and output were accounted for nitrogen and phosphorous. The MATLAB pdepe feature, applying the ﬁnite element method was used in model solving and the simulation of model equations. The program was split into four functions that included the solver and post-processing of the results, a function containing the PDEs, a function setting the initial conditions, and one setting the boundary conditions. For model validation, the experimental measurement of nitrogen, phosphorous and macroalgae biomass concentrations of Bandar Abbas coastal open waters were analyzed by standard methods at three depths of 1, 5 and 10 m. The predictive values of the developed model demonstrated its applicability for the management of coastal macroalgae cultivation systems by assessing the impact of nitrogen and phosphorous strategies on the farming system.
A New Second Order Approximation for Fractional Derivatives with Applications
Authors: M.Nasir Haniffa , Nafa Kamel
Published: May 2018

We propose a generalized theory to construct higher order Grünwald type approximations for fractional derivatives. We use this generalization to simplify the proofs of orders for existing approximation forms for the fractional derivative.  We also construct a set of higher order Grünwald type approximations for fractional derivatives in terms of a general real sequence and its generating function. From this, a second order approximation with shift is shown to be useful in approximating steady state problems and time dependent fractional diffusion problems. Stability and convergence for a Crank-Nicolson type scheme for this second order approximation are analyzed and are supported by numerical results.
Heat Transfer in Fe3O4-H2O Nanofluid Contained in a Triangular Cavity Under a Sloping Magnetic Field
Authors: M.Rahman Mohammad
Published: May 2018

Numerical simulation is performed to explore the convective heat transfer characteristics of Fe3O4-H2O nanofluid contained in a right-angle triangular cavity considering three types of thermal boundary conditions at the bottom wall. No heat is allowed to escape through the insulated vertical wall, whereas the inclined wall is kept colder than the bottom one. A sloping magnetic field whose strength is unvarying acts upon the cavity. The physical model is converted to the mathematical form through coupled highly nonlinear partial differential equations. These equations are then transformed into the non-dimensional form with the help of a group of transformations of variables. A very robust pde solver COMSOL Multiphysics that uses the ﬁnite element method (FEM) of Galerkin type is applied to carry out the numerical calculation. Heat transfer escalation through middling Nusselt number at the lowermost cavity wall is explored for diverse model parameters and thermal circumstances. The outcomes lead us to conclude that a higher degree of heat transfer is accomplished by reducing the dimension of nanoparticles and aggregating the buoyancy force through the Rayleigh number. It is highest when there is a magnetic field leaning angle of 900 and the lowermost wall is heated homogenously.

The Mathematical Modelling of a Fixed Source of Dust
Authors: S.M. Al-Mashrafi Khaled
Published: May 2018

A mathematical model for the diffusion of dust particles emitted from a fixed source is investigated using the atmospheric diffusion equation. This model poses an initial boundary value problem with a second order linear partial differential equation. The steady state case of this problem when the uniform source is situated at ground level was examined by Sharan et al. [1]. The solution of the unsteady case in closed form for a time dependent source is derived. Two special cases, in which the source function of time is explicitly given and special values of the diffusion parameters are taken, are examined in detail. In the case when diffusion is present only in the vertical direction, it is shown that for small times, the particles spread with a front that travels with the speed of the wind. When diffusion is present only in the direction of the wind, there is no discontinuity front and the particles diffuse slowly into the direction of the wind. The solutions for the special cases considered are examined for large values of time. It is found that the solution approaches that of the corresponding steady state solution of the equation.

Authors: Roata Ene Cristian , Morosanu Corneliu , Makkai-Popa Silviu-Tiberiu , Morarasu Stefan , Lunca Sorinel , Dimofte Gabriel
Published: May 2018

Introduction. Distal Hypoperfusion Ischemic Syndrome (DHIS) is a multifactorial debilitating condition causing peripheral ischemia and potentially tissue necrosis. In an effort to further refine its surgical treatment we aim to describe a modified, simple and reliable technique for managing DHIS in patients with arteriovenous fistulas. Materials and Methods. Twenty-nine consecutive patients with DHIS operated by a single surgical team over a period of 7 years were included in the study. All patients underwent the same surgical technique: stenotic ligature. Outcomes were analyzed clinically and the effectiveness of the procedure was proven using McNemar test. Clinical variables were statistically analyzed in SPSS 17.0 for Windows. Results. The technique we used consists in performing a stenosing ligature on the vein, using a 0-silk suture, and adjusting the suture in order to achieve either a radial pulse or capillary pulse, while maintaining a good thrill at palpation of the vein. The procedure was successful in 83% of patients proved by immediate symptomatic relief. Paired data analysis showed significant decrease of all symptoms: cold extremity (p=0,021), paraesthesia (p less 0,001), pain (p less 0,001). History of coronary artery disease, arteriopathy or the absence of radial pulse is statistically correlated with an increased risk of developing DHIS. Conclusions. Stenotic ligature is a simple, cheap and reliable technique for managing DHIS with lower septic risks which can be easily performed under local anesthesia.

Published: May 2018

Introduction. Abnormal uterine hemorrhages (AUH) are the most common symptom for presentation to gynecologist. Any uterine bleeding other than menstrual bleeding, which concerns the duration, frequency, quality or quantity of the bleeding is considered abnormal. Material and Methods. We realized a retrospective study based on medical records of the patients admitted for abnormal uterine hemorrhage at “Saint John” Emergency Clinical Hospital, “Bucur” Maternity between 2013 and 2016. From the patients with AUH, we focused on those who underwent hysteroscopies. Results. Our study included 146 patients. The age of patients varied from 22 to 71 years. Abnormal uterine bleeding was most prevalent among women of 40-50 years (20%), and the mean age was 42.65%. 82.88% from our patients had obstetrical history and only 17.12% didn’t give birth either as an option, or from primary or secondary infertility. 7.53% of the patients were hypertensive and 5.48% had endocrine pathology. All patients underwent diagnostic hysteroscopy and 4.79% patients therapeutic hysteroscopy. The therapeutic measures that were made are: hysteroscopic resection of the endometrium (47.3%), excision of polyps (36.99%), sinechiolysis (8.22%) and myomectomy (2.71%). The diagnoses were 46.48% endometrial polyp, 13.7% intramural leiomyoma, 13.7% IUD (intrauterine device) and 9.59% intrauterine synechiae, while 15.06% cumulated for uterine septum, endometrial hyperplasia, cervical polyp, foreign intrauterine bodies, secondary infertility, dysfunctional metrorrhagia. Conclusions. In patients with abnormal uterine hemorrhages, hysteroscopy provides the most accurate diagnosis and can reduce the burden of hysterectomy in many cases.

Published: May 2018

Objectives. Vulvar cancer is a rare gynecological malignancy, with an incidence of 1.5 per 100 000 women/year. The most common vulvar cancer is developed in squamous cells, the most encountered type of skin cells. Case report. We report a case of a 72-year-old female admitted in the Department of Plastic Surgery of Emergency Clinical Hospital “Prof. Dr. Agrippa Ionescu” with a 5/4.2 cm painful ulcerated tumoral mass located in the vulvar area. The lesion slowly increased in size over the past 12 months. The tumour was surgically removed with oncological safety margins and sent for histopathological evaluation. The histopathological examination revealed an ulcerated squamous carcinoma with lymphovascular and perineural invasion, but with negative margins. Postoperative results were favorable, and no local or general complications were observed. Conclusion. We highlight this case due to its unusual presentation in the clitoral area. Moreover, considering the potential for recurrence we point out the importance of the radical vulvectomy with regional lymphadenectomy and histopathological examination, in order to put a precise diagnosis and ensure the best possible treatment for the patient.
Subcutaneous metastasis from endometrial cancer; case report and literature review
Authors: Bacalbasa Nicolae
Published: May 2018

Subcutaneous metastases from endometrial cancer are rare situations, only few cases being described so far. The main incriminated mechanisms leading to the apparition of such lesions include hematogenous and lymphatic spread. We present the case of a 66-year-old patient known with previous history of stage IIIA endometroid endometrial carcinoma initially treated by surgery and adjuvant chemotherapy who developed at 18 months follow-up a distant subcutaneous oligometastasis. At this time the patient was resubmitted to surgery, the lesion being successfully removed. The histopathological result confirmed the endometrial cancer origin of this lesion. Subcutaneous and cutaneous metastases from endometrial cancer are rare eventualities which are usually diagnosed as part of systemic dissemination of this malignancy; in these cases, the patient is only candidate for oncological treatment with palliative intent. In some cases, in which the lesions occur as oligometastatic disease, surgery might be performed with curative intent. In our case the diagnostic of the subcutaneous lesion as oligometastatic disease transformed the patient in a perfect candidate for curative oncological surgery.

Published: May 2018

Colorectal cancers are one of the most frequent malignancies worldwide. Significant differences are described in relation to the location of tumors within the colon. Thus, between right and left colon cancer there are epidemiological, clinical, genetic, evolutionary and prognostic differences. Considering these premises, right and left colon cancers can be seen as distinct pathological entities. In right colon cancer the initial phases are often asymptomatic and the presence of symptoms is in relation to advanced phases and complications. We report the case of a 64-year-old man with no significant medical history who was admitted and operated as an emergency for stenotic and perforated tumor of the right colon. Operative exploration revealed distended small bowel loops and caecum up to the ascending colon where a stenosing tumor is found. The tumor extends to a small bowel loop and also exhibit a perforation. Right hemicolectomy was performed, with favorable postoperative evolution and discharge on 7th day.

Published: May 2018

Basal Cell Carcinoma is the most common human malignant neoplasm. Vulvar basal cell carcinoma is rare, accounting for less than 5% of all vulvar neoplasms. Vulvar basal cell carcinomas are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They are usually diagnosed late because they are often asymptomatic. However, these tumours may appear in areas which are normally covered with ultraviolet light. We present the case of a 60 years old woman diagnosed with invasive breast cancer for which she underwent surgery followed by chemotherapy and radiotherapy. The patient presented to our department with an ulcerated vulvar lesion. On inspection, the tumour measured 3/2 cm and was located on the left labium majus. The biopsy confirmed the diagnosis of vulvar basal cell carcinoma and a wide local excision was performed with no relapse at one year. In conclusion, early detection of BCC’s is critical to allow complete surgical cure so any abnormality on the vulva should be biopsied. A wide safety margin of 1cm should be achieved when resecting the tumour and the physician should keep in mind that the BCC’s of the vulva has a high recurrence rate. Previous chemotherapy is not associated with this type of non-melanoma skin cancer.

Published: May 2018

Objective. The purpose of this paper is to review the current concepts in the literature regarding the beneficial effects of adjuvant surgery after concurrent radio-chemotherapy for locally advanced cervical cancer. Method. Research of the literature was performed using PubMed databases in order to find articles relevant to the central topic. The PICOS criteria were used to filter the results. The paper was then structured according to the PRISMA guideline. Results. 50 individual papers were analyzed and sorted according to their relevance for the topic. 18 were classified as relevant. There was little agreement as to how beneficial adjuvant hysterectomy is in locally advanced cervical cancer after chemoradiotherapy. Some articles concluded that patients with a total clinical response after initial treatment might have superior progression-free survival and overall survival after surgery. 2 articles underlined the importance of accurate restaging after primary treatment. The lack of benefit for surgery in patients with bulky disease or persistent adenopathies was agreed upon in all cases. Conclusions. The decision for adjuvant hysterectomy with or without lymphadenectomy is a controversial one and has to be personalized and taken in a multidisciplinary team.

Authors: Poluakan Lingkan Claudia , Purwaningrum Pramiati , Indrawati Dwi
Published: May 2018

Tangerang City is one of the cities in Banten Province. The dense population causes an increase in the volume of waste, so an adequate Solid Waste Facility (SWF) is needed. Solid Waste Facility is the place to process and return the waste to the environment. Rawa Kucing SWF is one that serves Tangerang City with an area of 37.7 hectares, divided into four landfill zones and landfill support facilities. With the remaining land that can be used to build a new landfill, it is necessary to conduct a study on the feasibility of Rawa Kucing SWF if it is still feasible as seen by the environmental conditions or not. In the Regulation of the Minister of Public Works Number 3 of 2013, there is a land suitability assessment for taking decision of SWF whether it is to be rehabilitated or should be closed known as the Integrated Risk Based Approach (IRBA). The result of the environmental risk index assessment based on IRBA is 599.03, which means that mean Rawa Kucing SWF is included in moderate hazard category. The recommended action in this category is that the TPA is continued and rehabilitated into gradually controlled landfill. Currently, the Rawa Kucing SWF has applied controlled landfill method, so the effort to develop the landfill method into sanitary landfill method can be done gradually to reduce adverse impact to the environment. Technology such as Waste-to-Energy (WtE) Plants can also be considered to reduce the waste load entering the landfill.

Published: May 2018

Source of raw water used at Badak Singa Water Treatment Plant come from surface water such as Cisangkuy River. This source of raw water is affected by conditions in the upstream, pollution along the stream, climate and weather. In the drinking water supply system, turbidity is one important factor for several reasons such as aesthetic factor, burden to filtration, and interfere the disinfection process. Electro coagulation is one of water treatment method that combines the process of coagulation, flotation, and electrochemical. Aims: This research aims to see at the ability of the electro coagulation process in reducing turbidity as an alternative to substitute the conventional coagulation system. Methodology and results: This research carried out by testing electro coagulation with variations in mixing, current density produced by voltage 10, 20 and 30 volt and detention time 5, 10, 20 and 30 minute to reduce the initial turbidity of 100 NTU. The result are that: the efficiency of electro coagulation with mixing is better than electro coagulation without mixing to reduce the initial turbidity of 100 NTU; the final turbidity value of the processing result is better as the length of detention time used and meet the quality standard from detention time of 10 minute; the higher the current density given and the longer the detention time used, the higher the processing efficiency and the formed flock volume is deposited.  Conclusion, significance and impact study: A good turbidizing removal process using electrocoagulation requires the agitation process and long detention time.
Study on the Optimum Flushing Volume of the Sewer System in South Tangerang City
Authors: Marsudi Maudi Larasati , Tazkiaturrizki T. , Winarni W.
Published: May 2018

Aims: This planning aims to obtain the optimum flush volume on the design of sewerage in South Tangerang City. Methodology and results: Factors affecting this flushing are the length of pipelines, the service area, and topographic conditions. The sewer drain that needs flushing is Line 1–WWTP since the minimum velocity is not eligible due to its relatively low average topographic slope. The flushing is required particularly for the Section 1–2. Hence, two alternatives were devised by dividing the Population Equivalent (PE) in Section 1–2 into three segments. Those alternatives were differentiated by the PE—20%, 5%, and 75% for Alternative 1; whereas 10%, 15%, and 75% for Alternative 2. Alternative 1 requires flushing on Section 1–1.1 since it has a dmin of 7 cm and vmin of 0.2585 m/s, yielding a flush volume of 3.94 m3 (0.0193 m3/s). Section 1.1–1.2 still needs flushing because this channel has a vmin of 0.4281 m/s and a qualified dmin of 15 cm, generating a flush volume of 7.89 m3 (0.2113 m3/s). Flushing is not necessary for Section 1.2–2 due to its sufficient dmin of 63 cm and vmin of 0.88 m/s. Alternative 2 requires flushing on Section 1–1.1 since it has a dmin of 7 cm and a vmin of 0.2585 m/s, resulting in a flush volume of 2.63 m3 (0.0193 m3/s). Section 1.1–1.2 still requires flushing on account of its vmin of 0.3877 m/s and the yielded flush volume of 18.4 m3 (0.2625 m3/s), though its dmin of 13 cm complies with the standard. Section 1.2–2 does not need flushing as it already has a dmin of 63 cm and a vmin of 0.88 m/s. The total flush volumes for Alternative 1 and Alternative 2 are 11.83 m3 and 21.04 m3, respectively. Conclusion, significance, and impact of the study: The total flush volume for Alternative 1 is 11.83 m3, while Alternative 2 is 21.04 m3. Thus, the optimum design having the least flush volume is Alternative 1.

Published: May 2018

Aims: This study aims to analyze and select wastewater treatment technology that can be applied to riverbank settlement areas through environmental impact evaluation using LCA. The technology option is selected through the physical condition of the settlement environment on the river banks and then analyzed descriptively by making a flow chart of the processing technology options and compared with the wastewater treatment technologies that have been applied to residential areas of river banks or other swamp settlements. Methodology and results: The technology options will be analyzed and evaluated for potential environmental impacts of the construction and operation phase, using LCA through SimaPro8.4 software with an impact analysis using CML2 Baseline 2000. The impacts analyzed include acidification, eutrophication, global warming, ozone depletion. The results showed that the selected technological options were septic tanks, tripikon-s, and biofilter. In an environmental impact analysis it is known that the construction phase is a phase that contributes greatly to the potential environmental impacts. The potential for acidification and global warming are the dominant potential impact from the three technology options, with a contribution of 2.01x10-10 kgSO2-eq for the potential of acidification and 1.11x10-10 kgCO2-eq for global warming potential with biofiltration as a main contributor. The eutrophication potential is caused by nutrients (Total Nitrogen and Phosphorus) that come out along with the treated wastewater at the operating stage. The greatest eutrophication potential is generated on the Tripikon-S, at 2.3x10-10 kgPO4-eq. The potential for ozone depletion, biofiltration contributes significantly to 3.09x10-12 kgCFC-11-eq.  Conclusion, significance and impact study: Based on the comparison of technology, it is known that Tripikon S has the potential for environmental impact is quite minimal and can be an option to be applied to the river banks.

ÖZET

Uluslararası ilişkileri
anlamada çok önemli bir yere sahip olan güç kavramına her bir uluslararası
ilişkiler teorisi farklı bir pencereden bakarken, 1990’lardan itibaren akademik
alanda olduğu kadar medya ve siyasetçiler üzerinde popülarite elde eden yumuşak
güç kavramı, güç tartışmalarına yeni bir soluk getirmiştir. Gücü inşacı ve
neo-liberal bir yaklaşım çerçevesinde ele alan yumuşak güç, Joseph S. Nye
tarafından ilk kez “Liderliğe Zorunluluk: Amerikan Gücünün Değişen Doğası” adlı
eserinde, Amerikan ulusunun 1980’ler boyunca düşüşte olduğu bir dönemde Amerika
Birleşik Devletleri hegemonyasının sürdüğünü açıklamak maksadıyla ele alınmış
bir kavramdır. Yumuşak güç kavramı, Joseph S. Nye tarafından 1990 yılında ele
alınmasını müteakip popülerleştirilmekle birlikte tartışmaları da beraberinde
getirmiş ve halen üzerinde uzlaşı sağlanamamıştır. Joseph S. Nye’ın
geliştirdiği bu kavrama yönelik eleştiriler, yapılan yumuşak güç tanımından;
yumuşak gücün kaynak, davranış şekli ve araçlarına; kavram ve ifadelerin
yeterince analitik süzgeçten geçirilmemesine veya bunların birbiri ile
karıştırılması suretiyle yaratılan terminolojik kaosa kadar geniş bir yelpaze
yer almaktadır.

Bu çalışmada Joseph S.
Nye’ın geliştirdiği yumuşak güç kavramına yönelik yapılan eleştiriler; kavramın
teorileştirilmesindeki yetersizliğe yönelik eleştiriler, yeni bir kavram olup
olmadığına yönelik eleştiriler, kullanım zorluğuna yönelik eleştiriler
başlıkları kapsamında incelenecektir. Çalışmada, yapılan bu eleştiriler
ışığında özellikle Nye’ın ele aldığı muğlak yumuşak güç tanımı, kaynakları ve
davranışları sorunsalına cevap bulmaya yönelik yeni bir yumuşak güç önerisinin
sunulması amaçlanmaktadır.
Measuring Alarm System Quality in ICUs (WIP)
Authors: Hüske-Kraus Dirk , Wilken Marc , Röhrig Rainer
Published: May 2018

Despite a vast and growing number of publications on alarm fatigue there seem to be few attempts to quantify in a systematic way the root causes or consequences of alarm fatigue. The paper describes such an attempt, based on the notion of quality dimensions of an alarm system. The concept as well as concrete instances of these dimensions were developed in a scoping review including focus group interviews and subsequent iterative refinement workshops. The resulting model goes beyond currently used statistics for describing alarm system quality and appears to be useful for the construction of tools to support clinical users in the management of their alarm system.
