B alanced fertilizer is an essential component that plays a significant role in improving the crop production and quality (Amjadian et al., 2021). Balanced fertilizer also play an important role plant development and yield formation, the presence of essential nutrients in balanced form is necessary (Hi-Abstract | Phosphorus (P), Zinc (Zn) and its application timing play a very important role in crop productivity. To study its effect on maize, an experiment was conducted at Fodder and Forage Crops Section Harichand, district Charsadda-Pakistan. Two levels of P (90 and 120 kg ha -1 ) and three levels of Zn (0 i.e., water spray only, 2.5 and 5 kg ha -1 ) were applied at three application stages (AS) i.e., full at vegetative stage V6 (AS 1 ), full at reproductive stage R2 (AS 2 ) and ½ at V6 and ½ at R2 stage (AS 3 ) along with an overall control were used in the experiment. Randomized complete block design was used with three replications. Most of the studied parameters were significantly affected by P, Zn and AT. Least days to tasseling (54) and silking (55), leaf areaplant -1 (4180 cm 2 ), leaf area index (2.8), plant height (255 cm) and days to harvest maturity (89 were significantly affected when120 kg P ha -1 was applied. Days to tasseling (53), days to silking (55), leaf areaplant -1 (4400 cm 2 ), leaf area index (3.1), plant height (258.6 cm) and days to harvest maturity (89) were significantly affected in plots treated at the rate of 5 kg ha -1 with Zn. In case of application stages (AS), when Zn was applied 1/2 at vegetative and 1/2 at reproductive growth stages significantly enhanced the plant height (260.8 cm). It can be concluded from the study that increases in the rates of P and Zn improved majority of the studied parameters. Similarly, application of Zn, half at vegetative stage (V6) and half at reproductive stage (R2) improved significantly the phenological parameters of maize crop in the agro climatic condition of the study area.

Extra corporeal membrane oxygenation (ECMO) is an artificial oxygenation facility, employed in situations of cardio‐pulmonary failure. Some diseases i.e., acute respiratory distress syndrome, pulmonary hypertension, corona virus disease (COVID‐19) etc. affect oxygenation performance of the lungs thus requiring the need of artificial oxygenation. Critical care teams used ECMO technique during the COVID‐19 pandemic to support the heart and lungs of COVID‐19 patients who had an acute respiratory or cardiac failure. Double Lumen Cannula (DLC) is one of the most critical components of ECMO as it resides inside the patient and, connects patient with external oxygenation circuit. DLC facilitates delivery and drainage of blood from the patient's body. DLC is characterized by delicate balance of internal and external flows inside a limited space of the right atrium (RA). An optimal performance of the DLC necessitates structural stability under biological and hemodynamic loads, a fact that has been overlooked by previously published studies. In the past, many researchers experimentally and computationally investigated the hemodynamic performance of DLC by employing Eulerian approach, which evaluate instantaneous blood damage without considering blood shear exposure history (qualitative assessment only). The present study is an attempt to address the aforementioned limitations of the previous studies by employing Lagrangian (quantitative assessment) and incorporating the effect of fluid–structure interaction (FSI) to study the hemodynamic performance of neonatal DLC. The study was performed by solving three‐dimensional continuity, momentum, and structural mechanics equation(s) by numerical methods for the blood flow through neonatal DLC. A two‐way coupled FSI analysis was performed to analyze the effect of DLC structural deformation on its hemodynamic performance. Results show that the return lumen was the most critical section with maximum pressure drop, velocity, shear stresses, and blood damage. Recirculation and residence time of blood in the right atrium (RA) increases with increasing blood flow rates. Considering the structural deformation has led to higher blood damage inside the DLC‐atrium system. Maximum Von‐Mises stress was present on the side edges of the return lumen that showed direct proportionality with the blood flow rate.

Phosphorus (P), foliar zinc (Zn) and its time of application plays an important role in crop productivity. To study its effect on maize, field experiment was conducted at Fodder and Forage Crops Section Harichand-Charsadda, Pakistan. The field experiment was conducted on 7 July 2021. Two levels of P (90 and 120 kg ha -1 ) and three levels of Zn (0 i.e., water spray only, 2.5 and 5 kg ha -1 ) were applied at three growth stages, full at vegetative stage (V6), full at reproductive stage (R2) and ½ at V6 and ½ at R2 stage along-with an overall control were used in the experiment. Randomized complete block design was used with three replications. The studied parameters were significantly affected by P, Zn and AT. Ear length (17.8 cm), ear weight (115.8 g), grains ear -1 (390) and thousand grains weight (257 g) had significantly affected when 120 kg P ha -1 was applied. Similarly, ear length (18.4 cm), ear weight (129.6 g), grains ear -1 (407) and thousand grains weight (258.33 g) were significantly affected in plots treated at the rate of 5 kg ha -1 with Zn. In case of growth stages, Zn applied half at vegetative and half at reproductive stages significantly enhanced the ear length (18.2 cm), ear weight (127.4 g), grain ear -1 (391) and thousand grains weight (255.5 g). It is concluded from the experiment that application of 120 kg P ha -1 significantly improved ear length, ear weight, grains per ear and thousand grain weight. In case of foliar application of 5 kg Zn ha -1 improved ear length, ear weight, grains per ear and thousand grain weight of cob. Similarly, in case of Zn application stages, ½ at vegetative and ½ reproductive stage will improve productivity of maize crop. Therefore,120 kg P ha -1 , 5 kg Zn ha -1 along with its application timing ½ at vegetative and ½ reproductive stage is recommended for the agro climatic conditions of Peshawar.
