Published: February 2024

The oil and gas industry is exposed to fow assurance issues such as wax deposition and scale precipitation. The sector has been tackling this issue using the chemical method while extensive research is being conducted to fnd an efective solution. The conventional method is costly and not eco-friendly. This paper focuses on using Jatropha curcas seed oil (JSO) blended with Ethylenediaminetetraacetic acid (EDTA) as a promising dual inhibition application solution to counter wax and scale deposition simultaneously. The experiment manipulates the temperature and concentration to determine the efciency of the inhibitor and its capability to improve fowability. Flowability and jar tests were conducted to analyze the blend’s ability to act as a dual inhibitor. The results prove that the blend of JSO and EDTA at the concentrations of 3 wt% and 1 wt%, respectively, at 70°C showcased a robust result in wax inhibition by enhancing the fowability of the crude oil. On the other hand, efective scale inhibition is achieved when 1 wt% JSO is blended with 1 wt% of EDTA at 27°C. The results obtained signifes the compatibility of JSO and EDTA blend in dual inhibition application when optimal temperature and concentration are achieved. Dual inhibition application is expected to be a one-stop solution for both wax and scale precipitation that is economically viable and safe.

Published: February 2024

Dalam merancang sebuah sistem manajemen pembelajaran (LMS) perlu untuk mempertimbangkan sisi User Interface (UI) yang mana berkaitan dengan interaksi pengguna dengan sistem dan juga User Experience (UX) yang berkaitan dengan respon, cara pandang, serta perasaanÂ pengguna saat menggunakan sebuah sistem. Namun dalam proses perancangan tampilan antarmuka sebuah LMS tidak melibatkan pengguna secara keseluruhan, serta kurang melihat akan faktor kebiasaan yang dilakukan oleh manusia. Human Centered Design (HCD) merupakan suatu metode pengembangan sistem interaktif dengan menitikberatkan kepada cara sebuah sistem digunakan secara langsung oleh pengguna. Untuk menentukan tolak ukur keberhasilan pada penelitian ini adalah dengan menggunakan 6 variabel User Experience Questionnaire (UEQ) yaitu Daya Tarik, Kejelasan, Efisiensi, Ketepatan, Stimulasi, dan Kebaruan. Uji coba pengguna terhadap antarmuka LMS diperoleh kesimpulan bahwa metode HCD dapat digunakan untuk membuat sebuah tampilan antarmuka dengan semua variabel tolak ukur UEQ tidak ada yang masuk kategori Below AverageÂ dan Bad, untuk variabel Daya Tarik masuk kategori Excellent, Kejelasan masuk kategori Above Average, Efisiensi masuk kategori Excellent, Ketepatan masuk kategori Good, Stimulasi masuk kategori Excellent dan untuk Kebaruan masuk kategori Above Average.

Perceived Barriers to Physical Activity among Overweight and Obese Adult Patients Attending General Out-Patient Clinic in Lagos University Teaching Hospital
Authors: Adeyemi Samuel Sogo, , Adeyemi Ayopo Felicia, , Ogunbanwo Babatunde Michael, , Akinosi Joel Oyekunle, 
Published: February 2024

Background: Globally, only 1 in 4 adults engage in the recommended amounts of physical activity for health. The increasing rates of physical inactivity are partly caused by perceived obstacles to physical activity. Physical inactivity is the primary cause of roughly 21-25% of the burden of breast and colon cancer, diabetes, and ischemic heart disease.
Study Aim: To determine the perceived barriers to physical activity among overweight and obese adult patients attending the GOPC, LUTH using the barrier portion of the Exercise Benefit and Barrier Scale (EBBS).
Methodology: The research was a cross-sectional, descriptive study conducted in LUTH. Data was collected by means of questionnaire and interview. Statistical package for social sciences (SPSS IBM) version 25 was used for data entry, cleaning, and assessment. Frequency and percentage were used to represent all categorical parameters, and means, standard deviation, or, in the case of skewed continuous variables, median and interquartile range, were used to summarize them via systematic random sampling, 285 overweight and obese adults between the ages of 18 and 64 were chosen.
Result: The majority of overweight and obese adults (78.6%) felt that there were moderate to high levels of barriers to physical activity, most of which had to do with physical exertion. Age, family type, highest degree of education, type of occupation, median earnings, co-morbidity, smoking, and alcohol consumption, though significantly associated with levels of perceived barriers, were not independent predictors of a high level of perceived barriers.
Recommendation: Further evaluation of the perceived barriers to physical activity should be carried out to identify overweight and obese adults who encounter high barriers to physical activity. During lifestyle counseling, physical exertion, the most common barrier subscale to physical activity in this study, should be considered and addressed as appropriate.
Levels of Phthalate Acid Esters in Drinking Water Bottled in PET (Polyethylene Terephthalate) and PC (Polycarbonates) Bottles - stored under Different Storage Conditions in Mwanza City, Tanzania

Bottled drinking water is widely advertised and sold in glass or, to a greater extent, plastic bottles with metallic or plastic caps, and is regularly drank by both children and adults. Mwanza City markets have many brands of bottled drinking water packed in PET and PC plastic bottles whose polymers may contain additives such as phthalates. Certain cancer types, hormone imbalances, and developmental delays have all been connected to these phthalates, which are harmful to human health. This study investigated, the effects of storage conditions, time spent in storage, and type of container polymer on the leaching of phthalates from packaging materials into particular brands of locally produced PC and PET bottled drinking water that are regularly consumed by adults and children and sold in Mwanza City markets. The method of determination was liquid-liquid extraction followed by chromatographic analysis for identification of the specific phthalates compounds.
The results that the lowest mean Di methyl phthalates (DMP) concentration in water packed in PET bottles was 0.085 µg/mL before storage and that the mean DMP concentration increased to 0.235 µg/mL following six months of storage at room temperature and outdoor temperature. Additionally, the 18.9-liter PET bottle migrated higher than the 1.5-liter PET bottle due to its larger surface area for water contact and higher surface-to-volume ratio; however, it was found that production contamination, not migration, was the cause of the higher Di methyl phthalates concentrations in the PC bottles. These findings suggest that storing PET bottles containing drinking water at room and outdoor temperatures for an extended period of time directly impacts phthalate migration. Furthermore, this study shows reusing plastic water bottles raises the risk that the inner surface will deteriorate and release more phthalates, which raises concerns about the safety of drinking water that has been prepared and stored in a plastic bottle.

Published: February 2024

The present study aimed to review the relevant literature for studies describing the treatment of gynecologic disorders with melatonin, and the clinical relevance of melatonin supplementation in the field of gynecology. We searched the following databases for articles published between 2011 and 2022 that investigated the pathophysiology of the relationship between melatonin and gynecological pathologies in humans: PubMed, MEDLINE, and Embase databases. The 10 included studies primarily focused on the effects of melatonin on patients with polycystic ovarian syndrome (PCOS), as a treatment to reduce pain and improve sleep quality in gynecological pathologies, and as a treatment option for endometriosis. The findings of the present literature review suggested that melatonin can be beneficial in the treatment of PCOS, dysmenorrhea, and endometriosis. The effects of melatonin on MR1A and MR1B receptors, which are present in the epithelial cells of the endometrial gland, in addition to its known analgesic, anti-inflammatory, and antioxidant properties were also addressed. We concluded that there is a vast field of research on melatonin supplementation and its effects on gynecologic disorders. We also verified the prospects of its use as a therapeutic agent in the auxiliary treatment of gynecological diseases.
A Tendon Sheath Tumour Presenting as Trigger Finger
Authors: ONI O. O. A. 
Published: August 2005

The symptom of trigger finger may be caused by a variety of lesions. This report describes a trigger finger caused by a tumour in the tendon sheath. Trigger finger refers to transient arrest of motion in a finger. It may be caused by a variety of lesions such as those of the volar plate (Yancey & Howard, 1962) and joint capsule (Aldred, 1954), structural abnormalities of the metacarpal head (Flatt, 1961), lacerations of the flexor tendons (Janecki, 1976) and ‘loose bodies’ (Milford, 1971). Triggering as a result of tumour of the tendon sheath does not, however, appear to have been reported.
Acute Calcific Periarthritis in a Child
Authors: MERCER N. S. G. , NEWMAN J. H. , WATT I. 
Published: August 2005

We wish to present an account of a child who developed acute calcification in his thenar eminence to highlight the difficulty in differentiation between calcific periarthritis, acute infection, on clinical grounds. Calcific periarthritis is due to hydroxy apatite crystal deposits in bursae, tendons and ligaments (Bonavita 1980) with characteristic radiographic appearances of opacities of variable density and shape around joints (Hitchcock 1959). The condition was first described in the shoulder, by Duplay in 1870 (Sandstrom 1938) and this remains the most commonly affected site. The hip, elbow, wrist, knee and ankle may also be involved but involvement of the hand is uncommon. Involvement in this site was first described in 1924 by Cohen (Carrroll 1955). The previously reported age span ranged from thirteen years upwards, with an average of forty-five years, both sexes being equally affected (Currey 1970, Hitchcock 1959, Bonavita 1980).
Brief report: Associations of parental warmth, peer support, and gender with adolescent emotional distress
Authors: Operario Don , Tschann Jeanne , Flores Elena , Bridges Margaret 
Published: August 2005

ABSTRACTThis is an exploratory study of the associations among parental warmth, peer support, gender, and emotional distress in a sample of 308 adolescents in the United States. Parental warmth was associated with less emotional distress, whereas turning to peers for support during family conflict was associated with more emotional distress. Gender moderated these associations in multivariate analyses. Emotional distress was highest among females who reported low levels of parental warmth and who turned to peers for support, in comparison with females who also turned to peers for support but had higher parental warmth. Findings contribute to a growing literature on contextual factors associated with adolescent psychosocial well‐being.
Transient biventricular dysfunction following pericardiocentesis
Authors: Ligero Carmen , Leta Ruben , Bayes‐Genis Antoni 
Published: August 2005

AbstractWe report the case of a 41‐year‐old woman admitted to the hospital due to cardiac tamponade as the first manifestation of a pulmonary neoplasm. The patient developed an early biventricular dysfunction and pulmonary edema after removal of the pericardial effusion, with complete recovery within ten days. Since transient ventricular dysfunction after pericardiocentesis is a very unusual complication, we present a review of the different mechanisms suggested in the literature to explain the pathophysiology of this rare phenomenon.
What Do Microbes Encounter at the Plant Surface? Chemical Composition of Pea Leaf Cuticular Waxes
Authors: Gniwotta Franka , Vogg Gerd , Gartmann Vanessa , Carver Tim L.W. , Riederer Markus , Jetter Reinhard 
Published: August 2005

Abstract
In the cuticular wax mixtures from leaves of pea (Pisum sativum) cv Avanta, cv Lincoln, and cv Maiperle, more than 70 individual compounds were identified. The adaxial wax was characterized by very high amounts of primary alcohols (71%), while the abaxial wax consisted mainly of alkanes (73%). An aqueous adhesive of gum arabic was employed to selectively sample the epicuticular wax layer on pea leaves and hence to analyze the composition of epicuticular crystals exposed at the outermost surface of leaves. The epicuticular layer was found to contain 74% and 83% of the total wax on adaxial and abaxial surfaces, respectively. The platelet-shaped crystals on the adaxial leaf surface consisted of a mixture dominated by hexacosanol, accompanied by substantial amounts of octacosanol and hentriacontane. In contrast, the ribbon-shaped wax crystals on the abaxial surface consisted mainly of hentriacontane (63%), with approximately 5% each of hexacosanol and octacosanol being present. Based on this detailed chemical analysis of the wax exposed at the leaf surface, their importance for early events in the interaction with host-specific pathogenic fungi can now be evaluated. On adaxial surfaces, approximately 80% of Erysiphe pisi spores germinated and 70% differentiated appressoria. In contrast, significantly lower germination efficiencies (57%) and appressoria formation rates (49%) were found for abaxial surfaces. In conclusion, the influence of the physical structure and the chemical composition of the host surface, and especially of epicuticular leaf waxes, on the prepenetration processes of biotrophic fungi is discussed.
A Plant-Specific Protein Essential for Blue-Light-Induced Chloroplast Movements
Authors: DeBlasio Stacy L. , Luesse Darron L. , Hangarter Roger P. 
Published: August 2005

Abstract
In Arabidopsis (Arabidopsis thaliana), light-dependent chloroplast movements are induced by blue light. When exposed to low fluence rates of light, chloroplasts accumulate in periclinal layers perpendicular to the direction of light, presumably to optimize light absorption by exposing more chloroplast area to the light. Under high light conditions, chloroplasts become positioned parallel to the incoming light in a response that can reduce exposure to light intensities that may damage the photosynthetic machinery. To identify components of the pathway downstream of the photoreceptors that mediate chloroplast movements (i.e. phototropins), we conducted a mutant screen that has led to the isolation of several Arabidopsis mutants displaying altered chloroplast movements. The plastid movement impaired1 (pmi1) mutant exhibits severely attenuated chloroplast movements under all tested fluence rates of light, suggesting that it is a necessary component for both the low- and high-light-dependant chloroplast movement responses. Analysis of pmi1 leaf cross sections revealed that regardless of the light condition, chloroplasts are more evenly distributed in leaf mesophyll cells than in the wild type. The pmi1-1 mutant was found to contain a single nonsense mutation within the open reading frame of At1g42550. This gene encodes a plant-specific protein of unknown function that appears to be conserved among angiosperms. Sequence analysis of the protein suggests that it may be involved in calcium-mediated signal transduction, possibly through protein–protein interactions.
Cosuppression of Eukaryotic Release Factor 1-1 in Arabidopsis Affects Cell Elongation and Radial Cell Division
Authors: Petsch Katherine Anne , Mylne Joshua , Botella José Ramón 
Published: August 2005

Abstract
The role of the eukaryotic release factor 1 (eRF1) in translation termination has previously been established in yeast; however, only limited characterization has been performed on any plant homologs. Here, we demonstrate that cosuppression of eRF1-1 in Arabidopsis (Arabidopsis thaliana) has a profound effect on plant morphology, resulting in what we term the broomhead phenotype. These plants primarily exhibit a reduction in internode elongation causing the formation of a broomhead-like cluster of malformed siliques at the top of the inflorescence stem. Histological analysis of broomhead stems revealed that cells are reduced in height and display ectopic lignification of the phloem cap cells, some phloem sieve cells, and regions of the fascicular cambium, as well as enhanced lignification of the interfascicular fibers. We also show that cell division in the fascicular cambial regions is altered, with the majority of vascular bundles containing cambial cells that are disorganized and possess enlarged nuclei. This is the first attempt at functional characterization of a release factor in vivo in plants and demonstrates the importance of eRF1-1 function in Arabidopsis.
