Three images from Gaza; a textual – structural reading

إنّ المقصد المتعيِّن من هذه القراءة هو تلمُّس تطبيقي ناهض على معطيات من لسانيات النص وتحليل الخطاب مضماره قصيدة صلاح عبد الصبور "ثلاث صور من غزة" التي تتعالق لوحاتها الثلاث متسابكة لتتألّف أمام القارئ نسيجًا يشكِّل بنية كلّيّة تمثّل حركة متواصلة، تتخلّق دلالاتها من رحم التجربة الشعرية الناهضة على عوامل مختلفة، منها "نكبة فلسطين"، وأعماق النفس الإنسانية المتحققة في المعيش العيني؛ فالشاعر صلاح عبد الصبور يستند إلى تجربة شعبية تسجِّل عدستها لحظاتٍ كانت وكائنة في حياة الإنسان الفلسطيني، وتَنْظِمها شعرًا، تُجسِّد الذات الشاعرة من خلاله مأساة العربي الفلسطيني، وعمق الجرح الغائر في وجه زمانه، حيث ضياع الوطن.The intended goal behind this investigation is to touch upon the applications of textual linguistics and discourse analysis of Salah Abdel-Sabour’s poem: “Thalath Suwar min Gaza”. The images of the poem intertwine to present the reader with a constant movement that form a structure the meaning of which emerges from the womb of poetic experience that tackles issues related to “the Nakba” and the depths of the human psyche.  Poet Salah Abdel-Sabour has an experience in folklore poetry that enables him to record moments in the lives of the Palestinians in poetic form, which embodies the self-poet through the tragedy of the Palestinian Arab and the depth of his wound as manifested in the loss of the homeland

Imaging and intervention for coronary artery disease following irradiation of malignant thymoma

Thymomas are rare malignant epithelial growths, constituting 20% of mediastinal tumours. Resection followed by irradiation may be employed in all thymomas except for stage 1 thymomas. Mediastinal irradiation is associated with coronary artery disease. The mean duration of presentation of post-irradiation coronary artery disease is 16 years (range 3-29 years). In our patient coronary artery disease was found only a year post irradiation. A 55 year old male who presented with complaints of dyspnoea, retrosternal chest pain and heaviness since one year underwent resection for malignant thymoma followed by radiotherapy. He presented with coronary artery disease a year after undergoing mediastinal irradiation. On follow-up, patient was treated successfully by coronary artery bypass graft. This case is an unusual occurrence and suggests that mediastinal irradiation may result in significant coronary artery disease as early as within one year

Construction of sediment budgets in large scale drainage basins : the case of the upper Indus River

High rates of soil loss and high sediment loads in rivers necessitate efficient monitoring and quantification methodologies so that effective land management strategies can be designed. Constructing a sediment budget is a useful approach to address these issues. Quantifying a sediment budget using classical field-based techniques, however, is labour intensive and expensive for poorly gauged, large drainage basins. The availability of global environmental datasets in combination with GIS techniques provides an opportunity for studying large basins. Following this approach, a framework is presented for constructing sediment budgets for large, data-sparse drainage basins, which is applied to the mountainous upper Indus River basin in northern Pakistan. The methodological framework consists of five steps: (1) analyzing hydro-climatological data for dividing the drainage basin into characteristic regions, and calculating sediment yields; (2) investigation of major controls on sediment yields; (3) identification and mapping of sediment source areas by spatially distributed modelling of erosional processes; (4) spatially distributed modelling of sediment yields; and (5) carrying out the sediment budget balance calculation at the basin outlet. Further analysis carried out on the Indus data has enabled a better understanding of sediment dynamics in the basin. Analysis of the available hydro-climatological data indicates that the basin can be subdivided into three characteristic regions based on whether runoff production and subsequent sediment generation is controlled by temperature (Region 1, upper, glacierized sub-basins), precipitation caused by the monsoon and western disturbances (Region 3, lower sub-basins), or a combination of the two (Region 2, middle reach sub-basins). It is also demonstrated that contrary to the conventional model, the specific sediment yield increases markedly with drainage area along the Indus River. An investigation of major controls on specific sediment yield in the basin indicates that percent snow/ice cover is a major land cover control for specific sediment yield. Spatially distributed erosion modelling predictions indicate that 87% of the annual gross erosion takes place in the three summer months with greatest erosion potential concentrated in sub-basins with high relief and a substantial proportion of glacierized area. Lower erosion rates can be explained by the arid climate and low relief on the Tibetan Plateau, and by the dense vegetation and lower relief in the lower monsoon sub-region. The model predicts an average annual erosion rate of 3.2 mm/a or 868 Mt/a. Spatially distributed sediment yield predictions made with coupled models of erosion and sediment delivery indicate that the Indus sub-basins generally show an increase of sediment delivery ratio with basin area. The predicted annual basin sediment yield is 244 Mt/a and the overall sediment delivery ratio in the basin is calculated as 0.28. The long-term mean annual sediment budget, based on mass balance, is characterized by a gross erosion of 762.9, 96.7 and 8.4 Mt, and a gross storage of 551.4, 66.1, and 6.5 Mt in the upper, middle, and lower regions of the basin, respectively. The sediment budget indicates that the major sources of eroded sediment are located in the Karakoram, in particular in the Hunza basin. Substantial sediment storage occurs on the relatively flat Tibetan Plateau and the Indus River valley reach between Partab Bridge and Shatial. The presented framework for sediment budget construction requires relatively few data, mostly derived from global datasets. It therefore can be utilized for other ungauged or poorly gauged drainage basins of the world

Patient communication in radiology: current status of breaking bad news among radiologists and radiology trainees in Pakistan

Breaking bad news can be an intimidating task for any physician. The aim of this study was to record the practices of breaking bad news to the patients by Pakistani radiologists and trainees. The radiologists and trainees attending the 26th National Radiological Conference in October 2010 in Karachi, Pakistan, were surveyed. The response rate was 76%. The respondents included residents (51%), private practicing radiologists (28%), academic radiologists (13%), and other trainees (8%). Most of the academic radiologists communicated with their patients. The daily frequency of breaking bad news by residents was noted, which was highest in the public teaching hospitals (71%). For severe abnormalities such as malignancy, 50% residents, 55% of the academic radiologists and 74% of the private practicing radiologists were very uncomfortable in disclosure of results. Differences in frequency of communication with patients were noticed with both different training levels, and different settings of practice in a developing country

Benign granulomatous polyp obstructing the bronchus.

Abstract Inflammatory endobronchial polyps are rarely encountered. We report a case of a 14 years old girl with a benign granulomatous polyp originating in the bronchus. Computed tomography scan showed an intraluminal soft tissue opacity while fiberoptic bronchoscopy revealed a large soft tissue mass completely occluding the left lower lobe. Rigid bronchoscopy under general anaesthesia identified a fleshy mass in the left main stem bronchus which was excised via bronchoscopy. The histopathology showed benign polyp with non-specific inflammation. The patient\u27s symptoms improved subsequently and no recurrence was reported till two years of follow-u

Addressing the Complexity of the Digital Divide and the Role of Government in Addressing It : Role of Government in Bridging the Digital Divide

The digital divide refers to the gap among citizens of a country or across borders due to the lack of ease of access to digital means for some and the difficulty for others. The possession of electronic gadgets, smooth internet connectivity, and other forms of digital communication can have a wide gap in availability among countries. This gap is mostly influenced by factors that are of infrastructural, political, cultural, demographical, generational, and socioeconomic nature. On account of developed and developing countries, the gap is disseminated and thoroughly complex. Although the developed nations around the globe proved to have narrowed digital divide as a major source of development and advancement in respective countries, it is quite challenging for emerging economies to adhere to the same processes for development. For an emerging economy, the prudent cost-benefit analysis carried out by the government can have varying effects on undertaking projects related to minimizing the digital divide. Nevertheless, the importance of narrowing the gap of the digital divide is unparalleled, and governments of emerging economies are realizing the benefits of it and investing their resources accordingly. Furthermore, information technology can be a catalyst in facilitating processes that save a lot of costs, bring holistic quality improvements, and implement effective and efficient government policies that lead to digitalization and sustainable consumption of resources. Consequently, governments are getting actively involved in the digitalization of their respective countries to turn their smart cities into more intelligent ones. Even so, it is important to understand that taking one policy to address all citizens is not realistic. Hence, understanding the foundational knowledge of the citizens, the demand of the population under various sectors, framing well-rounded policies with alternatives, and effectively and efficiently implementing them are extremely crucial.©2023 Emerald Publishing Limited.

Wilson’s disease in pregnancy: case series and review of literature

Background: Wilson’s disease is a rare, autosomal recessive inherited disorder characterized by impaired liver metabolism of copper leading to decreased biliary excretion and incorporation of ceruloplasmin levels mainly in the liver and brain. Untreated Wilson’s disease has been shown to cause subfertility and even in cases where pregnancy occurs, it often results in spontaneous miscarriage. Case presentations: We present four cases of successful pregnancy outcomes in three patients diagnosed with Wilson’s disease along with the literature review. All the patients were managed with zinc sulphate without any postnatal complications. Conclusion: Patients with Wilson’s disease receiving regular treatment who remain asymptomatic are usually able to conceive and achieve successful outcomes. However, these pregnancies should be considered high risk and merit regular surveillance

Observation of Single Top-Quark production with the CDF II Experiment

We present the observation of electroweak single top-quark production using up to 3.2 fb−1 of data collected by the CDF experiment. Lepton plus jets candidate events are classified by four parallel analysis techniques: one likelihood discriminant, one matrix-element discriminant, one decision-tree discriminant, and one neural-network discriminant. These outputs are combined with a super discriminant based on a neural-network analysis in order to improve the expected sensitivity. In conjunction with one neural-network discriminant using a complementary dataset of MET plus jets events with a veto on identified leptons we observe a signal consistent with the standard model but inconsistent with the background-only model by 5.0 standard deviations, with a median expected sensitivity in excess of 5.9 standard deviations

Frequency of endometriosis among infertile women and association of clinical signs and symptoms with the laparoscopic staging of endometriosis

OBJECTIVE: The study aimed to determine the frequency of endometriosis in women who underwent diagnostic laparoscopy for evaluation of infertility and the association of clinical, ultrasonographic and laparoscopic findings of endometriosis with the laparoscopic stages of the disease.METHOD: It was a retrospective study of women presenting to gynaecologic clinics of the Aga Khan University Hospital from January 1999 to December 2005 with primary complaint of primary or secondary infertility and were diagnosed with endometriosis through laparoscopy. Relevant demographic and clinical information was entered and analyzed in SPSS version 14.0.RESULTS: The frequency of endometriosis in women with primary compliant of infertility was found to be 16.8%. Statistically significant associations was found between staging of the disease and thin built (p=0.007) and restricted uterine mobility on pelvic examination (p=0.035). The patients\u27 ultrasound and laparoscopic examination showed significant association with staging of the disease with the presence of cysts on ultrasound (p-value \u3c 0.0001) and adhesions on laparoscopy (p valu

Clinical course and outcome of acute severe asthma (status asthmaticus) in adults.

Objective: To evaluate the clinical course and outcomes in patients with acute severe asthma in a tertiary care setting. Methods: The retrospective cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, and comprised data of patients of age 16 and above who were admitted with a diagnosis of acute severe asthma from January 2000 to December 2013.These patients had undergone clinical evaluation to assess the severity of illness as well as the complications and eventual outcomes. SPSS 16 was used for statistical analysis. Results: Of the 50 patients in the study, 41 (82%) were females. The overall mean age was 53.1±20.3 years. Ventilator support was required by 37(74%) patients. Presence of acidaemia was associated with the need for invasive ventilation (p\u3c0.033) which in turn was associated with increased hospital stay (p\u3c0.043). Complications were observed in 37(74%) patients, the most common being respiratory failure in 35(70%) and arrhythmias in 8(16%). Use of both non-invasive and invasive ventilation was found to be significantly associated with development of complications (p\u3c0.001and p\u3c0.009). A total of 4(8%) patients died. Presence of acidaemia was found to be significantly associated with mortality (p\u3c0.032). Conclusion: Overt acidaemia at initial presentation in patients with acute severe asthma was significantly associated with higher rates of invasive ventilation leading to increased hospital stay, complications and higher mortality rate
