Objective: To compare the ease of placement of arterial catheters using palpation versus ultrasound guidance under aseptic measures. Study Design: Quasi-experimental study. Place and Duration of Study: Combined Military Hospital, Rawalpindi Pakistan, from Feb to Aug 2022. Methodology: Patients of either gender, aged 18 to 90 years presenting to a paranesthesia clinic that required intra-arterial blood pressure monitoring were included in the study. After induction, under General Anaesthesia, arterial lines were placed following an aseptic technique using ultrasound or palpatory method; in Group-U (ultrasound) or Group-P (Palpation), respectively. Demographic variables of the patient along with hemodynamic readings and success rate at first or multiple attempts, along with the total time of cannulation, were recorded. Results: Out of the total 74 patients, 59(79.7%) patients belonged to ASA-1 Grade, and 15(20.3%) patients in ASA-2 Grade. The mean age of the patients was 48.3±16.3, while mean BMI was 25.42±2.8kg/m2. In Group-P, the first-pass success was achieved in 19(51.4%) patients as compared to 32(86.5%) in Group-U when ultrasound was used (p<0.05). Conclusion: The success rate in placing an arterial line using ultrasound was significantly greater than the conventional palpatory method. Therefore, ultrasound should be a preferred modality during intra-arterial line placement. [ABSTRACT FROM AUTHOR]

An experiment was carried out to evaluate the effect of varying levels of phosphorus on growth and yield parameters of pea (Pisum sativum L.) cultivars at Agricultural Research Station, Swabi-Pakistan, during the year 2016-17. The plots were prepared according to Randomized Complete Block Design (RCBD) with split plot arrangement that were replicated three times. Phosphorus levels (0, 30. 60, 90, and 120 kg ha-1) were subjected to main plots and cultivars (Meteor, Samrina Zard, Leena Pak and Pea-2009) to sub plots. Data was collected on growth and yield parameters of randomly selected plants in each treatment and replication. Results showed that phosphorus levels significantly affected all growth parameters. Maximum absolute growth rate (3.31cm day-1), leaflets plant-1 (102.61), pods plant-1 (16.43), pod length (9.53 cm), root weight (4.67 g), nodules plant-1 (19.97), 100 seeds weight (40.66 g) and yield ha-1 (5.71 tons) were recorded in plants treated with 90 kg ha-1 of phosphorus. The results pertaining to cultivars revealed that maximum absolute growth rate (2.81 cm day-1), leaflets plant-1 (100.87), 100 seeds weight (39.73 g), pods plant-1 (17.06), root weight (5.90 g), number of nodules plant-1 (18.66) and yield ha-1 (5.92 tons) were recorded in Leena Pak cultivar. The cultivar Leena Pak was found higher yielding as compared to other cultivars under this study. It can be concluded from the research findings that cultivar Leena Pak should be fertilized with 90 kg ha-1 of phosphorus for better performance in terms of growth and yield under the agro-climatic conditions of Swabi District-Pakistan.

Odonata is one of the most important and potential predatory order and is an excellent indicator of ecosystem health. Current study was conducted in order to explore the dragonflies fauna in District Swabi of Khyber Pakhtunkhwa, Pakistan. A comprehensive field survey was conducted to collect dragonfly adults using aerial nets. 19 sites of District Swabi were surveyed during summer seasons of 2015 and 2016. The study revealed 23 species from 15 genera under 3 families. The abundant family was recorded as Libellulidae that was comprised of 19 species belonging to 11 genera, family Gomphidae included 3 species belonging to 3 genera and family Aeshnidae included one species belonged to one genus. Detailed description of each species, valid scientific names, their habitat, ecological observation, collection date and distributional range for all recorded species are provided.
