Generalisasi Invers Suatu Matriks Yang Memenuhi Persamaan Penrose

Generalized inverse is an extension of the concept of inverse matrix. One type of generalized inverse of a matrix of size (m × n) with elements of the complex number is the Moore Penrose inverse is denoted by A+ . Moore Penrose inverse is the inverse of the matrix which must satisfy the four equations called Penrose equations. Generalized Inverse whereas only satisfy some (not all) of the four Penrose equations are divided into classes based on the number of equations that can be met Penrose, {1}-inverse, {1,2}-inverse, {1,2.3}-inverse, dan {1,2,4}-inverse

Acute myeloid leukemia in children in Pakistan: an audit

Objective: To see the clinical features and treatment of children with Acute Myeloid Leukemia (AML) in Pakistan. Setting: Tertiary referral at a specialist Hematology/Oncology center. Methods: Retrospective, chart-based review of children (less than 14 years) admitted to the hospital with a diagnosis of AML between January 1987 and August 1997. Results: A total of 23 patients were admitted. There were 18 males and 5 females. The mean age was 8 5 years. M3 was the commonest morphological subtype (43%). Twenty- two percent of the patients presented with hyperleucocytosis (TLC\u3e 100 x i09 /L) and 95% with an elevated LDH (\u3e548 lUlL). Pneumonia at presentation was seen in 29%. Of 23 patients 14 were evaluable for responses. Six patients died early (43%); 3 before starting the chemotherapy and 3 during the induction chemotherapy, 8/11 (73%) patients entered remission. The median survival was 9 months. Conclusion: The pediatric patients with acute myeloid leukemia present with advanced disease. There is a high early death rate (within 28 days of diagnosis). The long-term outcome was inferior to that reported in the literature (JPMA 52:247; 2002)

Long-term outcomes of acute myeloid leukemia in adults in Pakistan

Objective: To describe the long-term outcomes of Acute Myeloid Leukemia (AML) and to study clinico­pathological features at presentation, morphological subtypesand remission rates. Methods: Demographic information, response to therapy and survival of patients (\u3e14 years of age) admitted between January 1988 to August 1996 with acute myeloid leukaemia was retrieved and analysed. Results: Seventy-four patients were admitted with a diagnosis of AML during the study period. There were 43 males and 31 females. Age ranged between 15 and 70 years with a mean age of 38 years. The most common presenting feature was fever (67.5%) and the morphological subtype according to French-American-British Group (FAB) criteria was M4. Fifty-five patients received treatment and were evaluable for response and outcomes. Thirty-six (65.4%) patients had complete remission. Sixteen (29.1%) died during the first 28 days after starting induction chemotherapy. The median survival was 11 months. Six (11%) patients (4 females, 2 males) are surviving beyond 4 years (long-term survivors).Conclusion: Our study suggests that the long-term outcomes of adults with AML are comparable to what has been reported in the literature for patients who do not receive bone marrow transplants (JPMA 52:482;2002)

High-precision calculations of In I and Sn II atomic properties

We use all-order relativistic many-body perturbation theory to study 5s^2 nl configurations of In I and Sn II. Energies, E1-amplitudes, and hyperfine constants are calculated using all-order method, which accounts for single and double excitations of the Dirac-Fock wave functions.Comment: 10 pages, accepted to PRA; v2: Introduction changed, references adde

Directional felling within selective management system of Peninsular Malaysia: comparison between current and extended techniques

Directional felling has been implemented in Peninsular Malaysia as part of the Selective Management System (SMS) to obtain optimum yield from the forest resources while reducing damage to the environment and residual trees. Some questions regarding its effectiveness have been questioned a few times, resulting in a joint research project at Ulu Jelai Forest Reserve, Pahang, Malaysia to compare between the current directional felling technique and the new (extended) techniques, in terms of accuracy of tree felling, volume of felling logs, expected damage on residual trees, and time taken for tree felling. For this study, 38 trees were felled with the current and extended techniques. By using the extended technique, 91.3% of the trees were felled within the 0°-5° range, and 100% within the 0°-10° range, compared to 28.01% (within the 0°-5° range) using the current technique. The extended technique also recorded higher volume recovery (14% higher) and lower damage on the residual trees by almost 50%. However, the extended technique took longer time, i.e. 4.56 minutes per tree, as compared to 2.50 minutes. The main contributor to the difference is the presence of gauge cut in the extended technique. Generally, the studies suggest that the extended technique is preferred as it is safer to the feller and surrounding people, while reducing the collateral damage on the harvested trees, as well as the residual trees

Anatomical variations of hepatic artery using the multidetector computed tomography angiography

Background: The frequency of normal and aberrant hepatic arteries differs among ethnicities. The aim of our work was to study the frequency of normal and aberrant hepatic arteries among Egyptians using multidetector computed tomography (MDCT) and to compare our prevalence with the prevalence of other nationalities. In addition, the gender differences of such variations were clarified. Moreover, the arterial feeding of hepatic segment IV was determined. Materials and methods: The present study was carried out on 500 patients (409 males and 91 females). Abdominal CT was performed using two MDCT systems, a 64-row, and a 256-slice system. Results: According to Michel’s classification, the normal anatomy (type I) was observed in 369 (73.8%) cases, while anomalous hepatic arterial pattern was detected in 131 (26.2%) cases. These anomalies were distributed as follows: type II in 36 (7.2%) cases, type III in 60 (12%) cases, types IV and V in 5 cases for each (1% each), type VI in 14 (2.8%) and types VIII and IX in a single case for each (0.2% each). Neither type VII nor type X was detected. Nine (1.8%) unclassified cases were observed. According to Hiaat’s classification, the anomalies were distributed as follows: type II in 41 (8.2%) cases, type III in 74 (14.8%) cases, type IV in 6 (1.2%) cases, type V in a single case (0.2%) and type VI in 2 (0.4%) cases. Finally, 7 (1.4%) unclassified cases were observed. Common hepatic artery (CHA) originated from coeliac trunk in 98% (79.8% males and 18.2% females). It originated from the abdominal aorta in 0.4% and from the superior mesenteric artery (SMA) in 0.4%. It was absent in 1.2%. Right hepatic artery (RHA) originated from the CHA in 86.6% (69.8% males and 16.8% females) and from the SMA in 13.2% (11.8% males and 1.4% females) and from the abdominal aorta in 0.2% (a single male case). Left hepatic artery (LHA) originated from the CHA in 91.2% and from the left gastric artery (LGA) in 8.8%. The most common origin of the segment IV blood supply was the LHA in 60.8%, followed by the RHA in 35%. Less commonly, blood supply derived from the hepatic artery proper (HAP) in 1%. Combined supply derived from RHA and LHA in 0.8%, from the LHA and HAP in 2% and the least encountered was from the RHA and HAP in 0.4%. Conclusions: Hepatic artery variations among Egyptians have a different distribution when compared to such variations among other species. The normal hepatic arterial pattern was observed in 73.8%, while the anomalous was detected in 26.2%. The CHA originated from the coeliac trunk in 98%, the RHA originated from the CHA in 86.6% and the LHA originated from the CHA in 91.2%. The most common arterial supply of the hepatic segment IV is derived from the LHA (60.2%)

The Effect of Investment Opportunity Set on the Association Between Incentives and Earnings Management Level

The objective of this research is to investigate the effect of investment opportunity set on the association between managers' incentives to manage earnings and the level of earnings management. The incentives to engage in earnings management in this research measured by financial leverage level. firm's size, and public ownership or firm‘s common stock. Discretionary accrual is used to measure level of earnings management. Result show that there are positive discretionary accruals and evidence support argument that the liigher of investment opportunity set the greater positive effect of financial leverage and public ownership on the level of carnmgs management. Manager of firms with relatively more investment opportunity set would have wider opportunity or more discretion to manage reported earnings
