We introduce certain subclasses of bi-univalent functions related to the generalized Janowski functions and estimate the general coefficient bound for the newly defined classes. Also, we deduce certain new results and the improvement of known results as special cases of our investigation.Publisher's Versio

THE UNDERUSE OF SPIROMETERY IN ROUTINE MEDICAL PRACTICE FOR DIAGNOSIS AND MANAGEMENT OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD) PATIENTS IN KARACHI, PAKISTAN

Introduction: Spirometry is important in the diagnosis and management of chronic obstructive pulmonary disease (COPD), yet it is a common clinical observation that it is underused though the extent is unclear. This survey aims to examine the use of spirometry in the diagnosis and management of COPD patients in districts of, Karachi. Material and Methods: It is a cross-sectional survey involving four clinic settings: hospital-based respiratory specialist clinic, hospital-based mixed medical specialist clinic, general outpatient clinic (primary care), and tuberculosis and chest clinic. Thirty physician-diagnosed COPD patients were randomly selected from each of the four clinic groups. All of them had a forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio less than 0.70 and had been followed up at the participating clinic for at least 6 months for COPD treatment. Results: Of the 120 COPD patients, there were 111 males and mean post-bronchodilator FEV1 was 46.2% predicted. Only 22 patients (18.3%) had spirometry done during diagnostic workup, and 64 patients (53.3%) had spirometry done ever. Conclusion: We conclude that spirometry is underused in general but especially by non-respiratory physicians and family physicians in the management of COPD patients. More effort at educating the medical community is urgently needed. KEYWORDS: Pulmonary function tests; Specialist; Forced expiratory volume in 1 second (FEV1); Forced vital capacity (FVC)

Condition Survey for Evaluation of Pavement Condition Index of a Highway

Pavements are major means of highway infrastructure. Maintenance and rehabilitation of these pavements for the required serviceability is a routine problem faced by highway engineers and organizations. Improvement in road management system results in reduction of time and cost, the pavement condition survey plays a big role in the pavement management. The initial phase in setting up a pavement management system (PMS) is road network identification. A vital element of a PMS is the capacity to assess the present condition of a pavement network and anticipation of future condition. The pavement condition index (PCI) is a numerical index generally utilized for the assessment of the operational condition & structural reliability of pavements. Estimation of the PCI is dependent on the results of a visual inspection in which the type, severity, and quantity of distresses are distinguished. In this research, a pavement distress condition rating strategy was utilized to accomplish the goals of this study. The main targets of this research were to categorize the common types of distress that exist on “Lakhi Larkana National Highway (N-105)”, and to estimate the pavement condition index. Using these data, Average PCI for the highway section was calculated. PCI to assess the pavement performance, 10 out of 19 defects were recognized in the pavement, as stated by the PCI method. Results indicated that the common pavement distress types were depressions, polished aggregate, rutting, potholes, block cracking, and alligator cracking

Spatiotemporal Impact of Precipitation Trend on LULC Using Satellite Remote Sensing Technique in Khirthar National Park, Sindh Pakistan

: Water footprint techniques are extensively used for essential life chores. It also maintains the naturalecosystem. The variations in climatic spell are not only important to investigate the past and current scenarios, but it isalso useful to develop the water resource projects. The current study explored the spatial-temporal climatic variation ofdry and wet periods (between 1998 and 2010) using the digital image processing technique of ENVI (Environment forVisualizing Images) classics, satellite remote sensing g (SRS), and GIS. The results are organized for the reported periodi.e. between 1998 and 2010, showing the change detection of the hydrological effect in the dry and wet years. It shows asignificant change in the land use land cover (LULC) of vegetation, water, settlement, and ephemeral rivers followed by91%, 97.45%, 94.40%, and 62.94 % respectively through the wet year of 2010, in association with the dry period of1998. For more authentications, the Normalized Difference Vegetative Index (NDVI) image difference of the wet anddry period has also been evaluated, which has shown vegetation in large areas with more water potential in the wet year2010. The water potential can be used by diverting it to the natural depressions, ditches, and ponds for storage purposesand to increase recharge of groundwater by increasing its quality and quantity. The stored water could be utilized in thedrought-prone days for sustainable agriculture activities, to reduce the migration rate of the community, and to improvethe socio-economic conditions in the study area of Khirthar National Park

Design and Modeling of 9 Degrees of Freedom Redundant Robotic Manipulator

In disaster areas, robot manipulators are used to rescue and clearance of sites. Because of the damaged area, they encounter disturbances like obstacles, and limited workspace to explore the area and to achieve the location of the victims. Increasing the degrees of freedom is required to boost the adaptability of manipulators to avoid disturbances, and to obtain the fast desired position and precise movements of the end-effector. These robot manipulators offer a reliable way to handle the barrier challenges since they can search in places that humans can't reach. In this research paper, the 9-DOF robotic manipulator is designed, and an analytical model is developed to examine the system’s behavior in different scenarios. The kinematic and dynamic representation of the proposed model is analyzed to obtain the translation or rotation, and joint torques to achieve the expected position, velocity, and acceleration respectively. The number of degrees may be raised to avoid disturbances, and to obtain the fast desired position and precise movements of the end-effector. The simulation of developed models is performed to ensure the adaptable movement of the manipulators working in distinct configurations and controlling their motion thoroughly and effectively. In the proposed configuration the joints can easily be moved to achieve the desired position of the end-effector and the results are satisfactory. The simulation results show that the redundant manipulator achieves the victim location with various configurations of the manipulator. Results reveal the effectiveness and efficacy of the proposed system

Adoption of halal cosmetics: extending the theory of planned behavior with moderating role of halal literacy (evidence from Pakistan)

Purpose. The primary purpose of this study is to develop an extended Theory of planned behavior (TPB) model by adding religious commitment (RC) and self-efficacy as internal variables and investigating the effect of these variables on attitudes toward halal cosmetics. In addition, this study also examined the moderating role of halal literacy in the relationships between attitudes (ATT), subjective norms (SN), perceived behavioral control (PBC), and intentions to purchase halal cosmetics. Design/methodology/approach. The method of data collection used was self-administered surveys with customers in two stores in Karachi, Pakistan, yielding 267 valid questionnaires. To guarantee validity and reliability, convergent and discriminant validity analyses were conducted, and structural equation modeling (SEM) was advanced to assess the relationships between variables using SmartPLS 3.0 software. The interaction moderation technique has been used to examine the moderating effect of halal literacy on the purchase intention of halal cosmetics. Findings. The results show that RC and self-efficacy both significantly impact the attitudes of Gen Y. Normative beliefs also had a significant relationship with SN. Further, ATT and SN had a significant relationship with purchase intention (PI) of halal cosmetics, while PBC was non-significant. Furthermore, halal literacy is found to have a positive moderating influence on ATT and PI; and SN and PI. Lastly, the moderating effect of halal literacy does not exist in the relationship between PBC and PI. Research limitations/implications. Participants' characteristics should vary for future studies, and larger sample sizes may yield different results. It is critical for managers working in the cosmetic industry to monitor Muslim consumption patterns to develop strategies to reach Muslim consumers. This study reveals the effect of religious commitment, self-efficacy, and the moderating role of halal literacy on the behavioral attitudes of a booming market sector, which can guide marketing managers in developing more effective advertising campaigns. Originality/value. This paper contributes to the halal consumption literature by exploring religious commitment and self-efficacy as constructs for the very first time in the TPB model. This study is the first to explore the influence of halal literacy on Gen Y Pakistani Muslim consumer behavioral intention toward halal cosmetic products using the TPB model. The paper offers an extended TPB model framework that may be of interest to scholars, marketers, and policymakers
