1 RESUMO

 

A irrigação nos viveiros de mudas florestais é de grande importância para esta atividade, e a fim de garantir sua qualidade, devem ser feitas avaliações periódicas da uniformidade de distribuição de água e realizar ajustes para manter ou melhorar sua eficácia. Uma intervenção simples que pode ser feita nos viveiros de mudas com irrigação sobrecopa é a alteração da altura dos emissores. Desta forma, esse trabalho teve como objetivo avaliar a influência deste parâmetro sobre a uniformidade de aplicação de água, usando como indicadores principalmente a Uniformidade de Distribuição (CUD) e o Coeficiente de Uniformidade (CUC). Os ensaios foram realizados no viveiro de mudas do IFRJ campus Pinheiral, com os microaspersores dispostos na altura de 2,35 m e de 1,85 m. Observou-se que o rebaixamento dos emissores proporcionou uma melhoria relativa de pelo menos 6% na uniformidade de aplicação de água, sendo recomendada a sua adoção.

EFFECT OF THE EMITTERS HEIGHT ON WATER APPLICATION UNIFORMITY IN NURSERY

 

 

2 ABSTRACT

 

Irrigation in nurseries is of huge importance to this activity, in order to ensure their quality, periodic evaluations should be done to maintain or improve their effectiveness. A simple intervention that can be done in nurseries with overhead irrigation is the change in the emitters height. In this way, this work had the objective to evaluate the influence of this parameter on the uniformity of water application, using as mainly indicators the Lower Quarter Distribution Uniformity (DU) and the Coefficient of Uniformity (CU). The tests were carried out in the nursery of the IFRJ Campus Pinheiral, with the micro sprinklers arranged at the height of 2.35 m and 1.85 m. It was observed that the lower height provided a relative improvement of at least 6% in the uniformity of water application, being its adoption recommended.

Observation of co-culturing cells on porous silk fibroin films
Authors: Zhu Shixin , Wang JiaMin , Sun Ziling
Published: October 2018

Porous silk fibroin films (PSFFs) are widely used in skin regeneration. Prevascularization of PSFFs is a successful strategy for enhancing the survival of engineered tissues in vivo. The adhesion and migration of human umbilical vein endothelial cells (HUVECs) and fibroblasts on PSFFs were observed by scanning electron microscopy and confocal laser scanning microscopy after vital staining of the cells. PSFFs could attract a large number of HUVECs and fibroblasts to pores in an interesting alignment and support them to spread well from the outside of pores to the center of PSFFs to form cell layers. PSFFs showed minor structural changes due to less degradation for 12 d culture, and cell layers overlapped from pores to the center in PSFFs. The total DNA assay indicated excellent cell proliferation on PSFFs on days 1 and 6 and no difference between co-culturing HUVECs and mono-HUVECs and monofibroblasts. PSFFs could guide cell migration and arrangement to form pore-centered and vessel-like structures without additional coating of proteins. The authors’ aim was to study the potential prevascularization of porous silk fibroin scaffolds by co-culturing HUVECs and fibroblasts. This model has potential application for angiogenesis in dermis regeneration in the future and provides a suitable microenvironment for the development of capillary-like structures.
Amylase-assisted green synthesis of silver nanocubes for antibacterial applications
Authors: Pandey Anamika , Shankar Shiv , Shikha  , Arora Naveen Kumar
Published: October 2018

In the present study, a bacterium producing alpha-amylase (Enzyme Commission number 3.2.1.1), Pseudomonas sp. (National Center for Biotechnology Information accession number KY548391.1), was isolated from decaying tea waste. The bacterium produced 15 U/ml amylase under submerged culture condition. Partially purified alpha-amylase (30 U/ml) from this bacterium was used to synthesize silver nanoparticles (AgNPs). The bioinspired synthesis of AgNPs was confirmed by ultraviolet–visible (UV–Vis) spectroscopy, Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM-EDX) techniques. UV–Vis studies revealed a surface plasmon peak at 435 nm, suggesting the amylase-mediated synthesis of AgNPs. FTIR analysis showed peaks indicating the presence of a thiol group in cysteine and carbonyl groups of amino acid residues and peptides of proteins interacting with silver nitrate responsible for stabilization of AgNPs. SEM confirmed the formation of polydispersed AgNPs that had diameters ranging from 63 to 142 nm and a cubical shape. The EDX spectrum showed a higher percentage of silver (84·09%) signal. Synthesized nanoparticles showed excellent antibacterial activity against multidrug-resistant bacterium Staphylococcus aureus. The present study proposes the advanced application of alpha-amylase in the synthesis of AgNPs and endorses them as an effective antibacterial agent against human pathogenic bacteria such as S. aureus.
Queensferry Crossing, UK: cable-stayed bridge deck and cables – design and construction
Authors: Curran Peter , Platt Alan , Vasquez Antonio , Baralos Paul
Published: October 2018

The new Queensferry Crossing near Edinburgh in Scotland, UK, is a cable-stayed bridge with a total length of 2637·5 m and three towers up to 210 m high. The two cable-supported main spans are 650 m long, the two back spans are 223 m and there are approach viaducts at each end of the variable spans, up to 104 m long. The two cable planes are arranged centrally between both carriageways and overlap in the centre of the main spans. This special feature is necessary in order to stabilise the deck and, especially, the central tower. Unique design features, such as having the world's longest pair of free-standing cantilevers with an overall length of 644 m, and constructing the works in an exposed location in adverse weather conditions put very high demands on the engineers and workers involved. This paper describes the design and construction of the cable-stayed bridge deck and cables.
Structural design of irregular curved lattice shells in China
Authors: Xu Jianshe , Fang Cheng , Wang Wei , Chen Guangming
Published: October 2018

Irregular curved lattice shell structures are proving increasingly popular in China. However, the behaviour of irregular shells can be substantially different from regular shells in terms of strength, stiffness and stability characteristics as well as joint detailing. This paper reviews a number of projects in China in which irregular shells have been used. The structural system, force transfer path, vulnerable locations and strengthening measures are discussed. This is followed by a case study on a 45 m span greenhouse building featuring novel drum joints in the shell.
Transverse thermal difference of high-speed railway roadbed in seasonally frozen regions
Authors: Zhang Yuzhi , Sun Baochen , Wen An , Cheng Boyuan
Published: October 2018

Transverse thermal regime differences are widespread for high-speed railway (HSR) roadbed in seasonally frozen regions. On the basis of the monitored data of four typical roadbed sections from Harbin–Dalian HSR in seasonally frozen regions of China, the external influence and heat absorption of different parts of the roadbed are studied quantitatively through the comparison of the temperature amplitude and average temperature; the characteristics of the frost penetration development are also analysed. The variations in temperature during the coldest and hottest months with depth are analysed as well. On the basis of these analyses, the influence factors and potential hazards of the transverse differences are discussed. It is stated that the west shoulders are most influenced by the external environment. The temperature in the coldest and warmest months at a certain depth is characterised by a spindle shape intersection. The increase in the latitude and roadbed height may aggravate the transverse thermal regime difference. In addition, the roadbed transverse thermal difference may induce uneven roadbed deformation; hence, the roadbed stability and the ride comfort of the track structure may be threatened. Therefore, further relevant monitoring and deformation mechanics studies should be conducted.

Authors: Rhim Hong Chul , Kang Jae-Yoon , Kim Young Ho , Kim Dae-Jin
Published: October 2018

In this study, a push-out test was performed on steel pile caps strengthened with newly proposed perfobond shear connectors, and the test results were analysed and subsequently discussed. The newly proposed perfobond connector can greatly simplify the complicated processes required for the conventional pile cap strengthening method with steel rebars, such as the distribution of reinforcing bars, their anchorage into concrete and the use of shear keys. In total, six specimens were manufactured and tested. Test parameters included the type of strengthening method, infilled concrete depth and the number of shear keys. The applied load–deformation curve was plotted for all test specimens and their failure modes were identified. Effects of the test parameters on the peak load are examined in this study. Three-dimensional nonlinear finite-element analysis was also performed and its results were compared with experimental results, confirming the effectiveness of the proposed perfobond reinforcing method.
Half-joint beam design based on the CFP theory
Authors: Kotsovos Gerasimos M. , Cotsovos Demitrios M.
Published: October 2018

The present work complements recent attempts to investigate the causes of vulnerabilities inherent in half-joint structures. Herein, such vulnerabilities are attributed to shortcomings of the mechanism of force transfer underlying the adopted methods of design, rather than the detailing of the specified reinforcement as widely believed. The work is intended to demonstrate that the forces in half-joint beams are transferred by beam action, and not by the strut-and-tie mechanisms assumed to develop in the presence of the specified reinforcement. Through the use of the compressive force-path method, which has been developed on the basis of a beam mechanism of load transfer, it is shown that the predictions of half-joint beam behaviour correlates closely with the findings of a finite-element analysis package which was at first shown to be capable of successfully reproducing the experimentally-established structural behaviour of such beams.

Background: There is high prevalence of obesity and smoking in Saudi population. Both are major risk factors for developing hypertension (HT) and MI. Associations between hypertension, MI and ABO blood groups have been shown but they are inconsistent. To date no such studies have been done in Saudi Arabia to determine association between ABO blood groups and prevalence of smoking, hypertension and MI in Saudi female patients.Methods: 432 control females were randomly selected and distribution of ABO and Rh antigens was statistically analyzed and compared with 78 smokers, 219 hypertensive and 311 MI female patients admitted to King Khalid hospital between the periods of August 2017 to May 2018.Results: Among controls 3.2% were smokers, 7.6% hypertensive and 13.2% diabetics. Among hypertensive 7.8% were smokers and 46.6% were diabetics. Likewise we also found statistically significant increase in prevalence of smoking (9.9%) and diabetes (48.2%) in MI female patients. Additionally about half of MI patients (49.8%) were hypertensive. 85.9% controls were Rh+ and 14.1% were Rh-. Rh+ subjects were significantly higher in hypertensive and MI patients also. O+ was most prevalent and AB+ was least prevalent in all groups.Conclusions: Statistically there was no difference between distributions of, B-, B+, AB-, AB+ blood groups, however there was high prevalence of A blood group in hypertensive (31.4%) and female MI patients (31.2%) as compared to A blood group among controls (24.8%). Distribution of O blood group wassignificantly lower in hypertensive (42%) and MI patients (41.5%) as compared to controls (53.1%).

Background: More than 50% of the diabetes mellitus (DM) subjects in India remain unaware of their diabetic status. The aim of the study was to screen and identify apparently healthy individuals for impaired glucose tolerance in Tehsil Kangra and adjoining areas of Himachal Pradesh, India.Methods: Cross sectional study with 80 apparently healthy subjects in the age group of 30 to 70 years were taken. Anthropometric parameters viz. weight, height and waist circumference of subjects were measured. Whole blood sample was used for estimation of glycosylated hemoglobin (HbA1c) and serum sample for fasting blood sugar (FBS) and some lipid parameters.Results: The prevalence of prediabetes in apparently healthy population was found to be 25%. Additionally, a significant increase was observed in the FBS levels in prediabetics as compared to healthy subjects. However, no significant change was observed in the mean body mass index (BMI), mean body surface area (BSA), waist to height ratio (WHtR) and lipid parameters between prediabetics and healthy subjects.Conclusions: The burden of prediabetes in apparently healthy subjects of Tehsil Kangra and adjoining areas was found to be 25% and this urgently calls for mass awareness and screening programmes to identify and overcome DM.
Imaging for biopsies
Authors: AlBalood Musaad , Almeshal Mohammed
Published: October 2018

Positron emission tomography/computed tomography (PET/CT) imaging technique is considered to be an advanced technique that emerged recently and has been successfully used to guide several procedures like obtaining biopsies and ablating tumors. In this review, we will thoroughly discuss the indications, uses, and advantages of guiding biopsies with PET/CT techniques, with main focus on the field of oncology. PET/CT techniques are considered to be emerging imaging modalities that have significantly improved diagnostic accuracy of biopsies. The most important advantage of using PET/CT imaging to guide biopsies is its ability to provide accurate visualization of the lesion, with immediate assessment of the procedure following its end. On the other hand, this technique still has some limitations. Most importantly, the significant exposure to radiation to both the patient and the physician.

Published: October 2018

Background: Chemoradiation forms the major line of treatment in advanced head and neck squamous cell carcinoma, but the benefit of chemotherapeutic agents is at the expense of various toxicities. Curcumin has demonstrated promising results in in-vivo and in-vitro studies as a radiosensitiser. The objective of the study was to determine the role of curcumin as an adjuvant in patients undergoing chemo radiation for advanced head and neck cancers.

Methods: Study involved 21 patients who underwent chemo radiotherapy for advanced head and neck cancers. They were randomized into two groups. Group A received 500 mg of curcumin while, Group B received placebo along with chemoradiation. The response was assessed using RECIST criteria at three months post treatment using contrast enhanced computerized tomography scan.  

Results: Overall 58.3% patients had partial response and 41.7% patients had stable disease in group A. In group B, 33.3% patients had a partial response and 66.6% patient had a stable disease.

Conclusions: Patients receiving curcumin along with chemoradiation had a marginal decrease in tumour volume and 58.3% patients had partial response and 41.7% had stable disease. A statistical significance could not be achieved due to lack of stage-match controls. Further studies are required to validate the role of curcumin as an adjuvant in the treatment of head and neck squamous cell carcinomas.

Methods: A retrospective study of 12 patients with profound hearing loss due to Meniere’s disease was done between January 1998 till June 2018 in a tertiary ENT centre in Chennai, India. The patients experienced symptoms of Meniere’s disease for an average of 10 years before CI. All were postlingual candidates. The aim of this study was to determine the effectiveness of cochlear implantation in improving hearing and to assess the impact of CI on vertigo and tinnitus in patients with Meniere’s disease.  

Results: Significant hearing improvement with CI was noted in all patients. Resolution of vertigo and reduction of tinnitus was noted. There was no vestibular dysfunction due to CI. In one patient with disabling vertigo, labyrinthectomy combined with CI helped in complete resolution of vertiginous symptoms.

Conclusions: Cochlear implantation is an established option for hearing habilitation in patients with Meniere’s disease, with good outcomes. In case there is disabling vertigo, combining labyrinthectomy with CI is recommended.
Role of arthroscopy for early diagnosis and early therapeutic intervention in knee synovitis compared to histopathology
Authors: Gandra Arvind
Published: October 2018

Background: Arthroscopy has been found to be very useful for early diagnosis and also found useful for early therapeutic interventions in patients with synovitis of the knee joint disorders. The objective of the study was to study the role of arthroscopy for early diagnosis and early therapeutic intervention in knee synovitis.

Methods: Hospital based prospective study was carried out at Department of Orthopedics, Dr. D. Y. Patil Medical College, Pune over a period of August 2006 to October 2008 among 30 cases as per the inclusion and exclusion criteria. All patients underwent arthroscopy, clinical examination and histopathology of knee joint tissues. Comparison was made between clinical diagnosis and histopathology as well as between arthroscopy findings and histopathology.

Results: Pain and swelling of knee joint was reported by all patients. Anemia was seen in 70% of the cases. The accuracy of arthroscopic diagnosis was more than clinical diagnosis. Where clinical diagnosis failed to diagnose conditions like villonodular synovitis, pyogenic synovitis and gouty arthritis, the arthroscopic diagnosis was 100% accurate in the first two conditions and 66.7% accurate in the last condition. Where clinical diagnosis was accurate to 80-83% in cases of rheumatoid arthritis, septic arthritis and tubercular arthritis, the arthroscopic diagnosis was 100% accurate. Where in case of osteoarthritis, the clinical diagnosis could identify only 20% of the conditions, arthroscopic diagnosis was able to diagnose 40% of the actual cases.

Conclusions: Arthroscopic diagnosis was more accurate as compared to clinical diagnosis and it was almost 100% in all cases of knee joint diseases except in two. Thus arthroscopic diagnosis can be relied upon and treatment can be started on this basis in view of time consuming and costly histopathological tests.

Authors: Sivayadevi P. , Anandan Heber
Published: October 2018

Background: Syphilis presents with a wide range of mucocutaneous and systemic manifestations, which can mimic many other diseases. The pattern of acquired syphilis is changing in recent years because of widespread use of antibiotics and HIV infection which leads to under diagnosis. Aim was to study the demographic factors and changing pattern of clinical features of acquired syphilis.

Methods: Retrospective analysis of all cases of sexually transmitted infections registered in the Department of Venereology, Thanjavur Medical College from January 2013 to December 2017 was done. The data regarding epidemiological, clinical and investigational details were recorded and analyzed for changing trends in incidence, pattern and clinical presentation of syphilis.

Results: Of the total 14,672 cases attended theSTI clinic, 140 patients were diagnosed as having syphilis. There were 101 (79.4%) males and 39 (27.8%) females. Primary Syphilis was diagnosed in 18 (12.25%), Secondary syphilis in 38 (27.14%) and latent in 84 (60%) cases. Palmoplantar syphilide was the most common skin manifestation seen in 20 (52.63%) cases of secondary syphilis. 11 (7.85%) patients was human immunodeficiency virus (HIV) reactive.

Conclusions: Our study indicates an increasing trend in the prevalence of syphilis cases in last 5 years with a rise in early symptomatic syphilis demanding steps to increase awareness among the general population.
Clinical evaluation of hirsutism in South India
Authors: Subha R. , Tharini G. K.
Published: October 2018

Background: Hirsutism is defined as the presence of terminal coarse hairs in women, in male distribution. Hirsutism affects approximately 5 to 10% of women of reproductive age. There are only very few studies from south India on associations of hirsutism. We analyzed the prevalence of hirsutism among different age groups, etiology and its associated conditions.

Methods: This prospective study was conducted in the Department of Dermatology, of a tertiary hospital in south India over a period of two years. Patients with Ferriman Gallway score of 8 or more were included in the study. Complete history, examination and investigations including USG abdomen & pelvis, hormonal assay were done for all patients. All our patients were screened for metabolic syndrome.

Results: A total of 73 patients with hirsutism were enrolled. Among them, 53 (72.6%) were in the age group of 15 to 35 years. Menstrual irregularities were seen in 35 patients (48%). Face was the commonest site of involvement. Serum total testosterone was elevated in 10 patients (13.7%). LH, FSH ratio was more than 2 in 12 patients (16.4%). Polycystic ovaries were seen on pelvic ultrasonogram in 20 patients (27.3%).

Conclusions: Idiopathic hirsutism was the most common cause of hirsutism in our study. In our study 30% of patients were obese. Among them, features of metabolic syndrome were seen in 31.8%, though majority of our patients were young.

Published: October 2018

Erythema multiforme (EM) is a hypersensitivity reaction to different antigenic stimuli, commoner being infection followed by drugs. It occurs predominantly in younger age group. EM has benign course but frequent recurrences are common especially secondary to HSV infection. Erythema multiforme present as classical cutaneous target/ targetoid lesions and mucosal bullae/erosions. Though almost 70% of patients suffer from mucosal involvement, isolated mucosal affection is very rare. Fuchs syndrome/ectodermosis pluriorificialis is a rare variant characterized by severe involvement of two or three mucosal sites in the absence of skin lesions commonly triggered by Mycoplasma pneumoniae. Here we are reporting a rare case of mucosal erythema multiforme secondary to drug and highlighting the importance of distinguishing it from other similarly presenting mucosal disorders.
Walker vs. Wheelchair User: Expected Gains from Lower Extremity Eccentric Resistance Training after Incomplete Spinal Cord Injury
Authors: Stone Whitley Jo , Stevens Sandra L
Published: October 2018

Individuals post Incomplete Spinal Cord Injury (iSCI) experience mitigated physical function relative to the degree of injury. Prolonged therapeutic interventions may include strengthening of the affected musculature below the lesion. Eccentric resistance training has shown to positively impact strength and function inferior to the iSCI. It has yet to be determined if the severity of injury impacts sensitivity to such exercise interventions. A 12-week lower extremity, eccentrically-biased resistance training program was implemented in a mixed sample of walkers (n = 4) and wheelchair users (n = 7) with iSCI. Strength, walking speed, mobility, and daily step activity were analyzed using multiple 1 way ANOVAs with percent improvement from pre- to post-test as the dependent variable and community traversing style as the independent-between factors. Traversing style made no impact on strength gained (eccentric and isometric) nor increase in daily step activity (p > 0.05). Chair users experienced greater improvement in walking speed (p = 0.03) and mobility (p = 0.025) when compared to the walkers, respectively. These preliminary data may represent a ceiling effect for community ambulators in respect to walking function without formal gait training. Alternatively, those using chairs may attain walking improvement in the absence of structured walking therapy. Further support is provided for implementation of lower extremity exercise training regardless of severity of iSCI as the trajectory of improvement in strength and step activity was similar between groups.

Authors: Matias Alexandra , Pacheco Diana , Brandão Otilia , Montenegro Nuno
Published: October 2018

Background: The agenesis of the ductus venosus (DVA) is a rare condition with a variable prognosis that relies partly on the presence of associated conditions. Therefore, the prenatal evaluation should include a careful examination of fetal circulation, particularly the umbilical and portal venous malformations.Methods In this study, we describe four cases of DVA diagnosed at our institution. For each case, we access the patient’s files in order to extract the following information: gestational age, umbilical vein connection, pre-natal imaging findings, gestational age at delivery or at pregnancy termination, fetal outcomes, post-natal imaging findings, post-mortem findings and karyotype.Results From the four cases included, two were diagnosed in the first trimester and the other two cases in the second trimester of gestation. Prenatal ultrasound studies revealed an intrahepatic shunt in one case and an extrahepatic shunt in three cases. In one case, the karyotype was not performed, whereas the other three had a normal karyotype. Cardiac anomalies were found in three of the four fetuses. All but one case presented with extracardiac abnormalities. None of the cases developed hydrops. Two cases are currently alive and well, one termination of pregnancy occurred at 25 weeks of gestation and one case died at 14 days during surgical correction of a complex cardiac malformation.Conclusions Clinicians should be aware of different and important findings during the fetal examination, which can be indicative of a DVA, and, when suspected, serial revaluations should be scheduled in order to identify any malformation.
Where the Pendulum of Knowledge Stands Now: Is Circulating Albumin a Marker of Inflammation or of Malnutrition? How to Manage Hypoalbuminemia by Nutrition?
Authors: Dioguardi Francesco Saverio
Published: October 2018

Low plasma albumin levels have been historically associated with insufficient nutritional nitrogen support.Recently, linked to the poor response of actual therapies and available supplements to manage this alteration, the role of this alteration has been attributed to the vast ensemble of modifications referred generally as consequent to inflammation. On the contrary, as recently it has been reported that life based on introduction of mainly essential amino acids is possible, and life span is improved when compared to standard diets, it is possible to hypothesize that by normal foods or by actually most widely diffused supplements insufficient amounts of essential amino acids to match with real needs of hypoalbuminemic patients are not provided. Peculiarly, some non essential amino acids provided in excess by diets may mislead clinicians by suggesting achievement of sufficient nitrogen intake if urea syntheses is used as reference of sufficient nutrition, while syntheses of liver proteins is not sufficiently implemented. Studies suitable to understand if some innovative therapy would be efficient in implementing albumin syntheses and thus prognosis in hypoalbuminemic patients are necessary.
Negotiating Egyptian Nationalism: Militant Islamist Confrontations with the State and the Fragmentation of Political Authority
Authors: Musekamp Catherine
Published: October 2018

Since Egypt’s 1952 Free Officer coup d’état, Egypt has been governed by authoritarian regimes and nationalism has served as the central ideological basis for political authority. This paper explores the period from the mid-1970s to the mid-1990s, when militant Islamist opposition toward the Sadat and Mubarak regimes was one of the most significant threats to state security and one of the biggest challenges to the ruling regimes’ hegemony over political authority. This paper argues that the negotiation of national identity was crucial to the Egyptian state’s confrontation with militant Islamist groups during the late Sadat presidency and the Mubarak era to the 1990s; however, the state’s endorsement of an “Islamized” Egyptian nationalism was co-opted by various state institutions and competing political groups, leading to a fragmentation of political authority.
