Occupational-Seasonal Spine and Other Orthopaedic Injuries due to Fall from Java Plum Tree

Background: Falling from a Java Plum (Jamun) tree is one of the primary causes of Spine and other extremity fractures during the Monsoon season (when it is harvested) in Pakistan. Objective: To assess the distribution of patients with different facture types presented with the history of fall from Jamun tree during Monsoon season. Study Design: Retrospective study Place and Duration of Study: Department of Orthopaedics & Spine Surgery, Ghurki Trust Teaching Hospital, Lahore 1st May 2020 to 31st August 2020, Methodology: Forty two male patients age ranged from 12-55 years of age were enrolled. Information was obtained from the hospital’s trauma registry, and medical records were retrospectively reviewed for data about the type of fractures, occupational status, pre-hospital immobilization, time of presentation, and the time between fall and management and length of hospital stay were reviewed. Results: The average age of the patient was 34.6 years. Twenty four (57.14%) had spine fractures and 18 (42.8%) suffered other axial and skeletal fractures. Nearly three-fourths needed surgical intervention. In contrast, 26.1 % were managed conservatively. Conclusion: During monsoon season, we received 4.6% of extra patients with different injuries following fall from Jamun tree. In most cases, young men from lower socio-economic status suffer from varying degrees of disability and experience financial problems.

MACROELEMENTS CONCENTRATION IN PLUM TREE LEAVES AND SOIL IN RESPONSE TO ORCHARD FLOOR MANAGEMENT

The aim of the study was to determine the influence of various methods of orchard floor management on extractable mactronutrients concentration in plum leaves and orchard soil. Study carried out between 2013 and 2015. Standard mineral fertilization on experimental plots was applied. Trees of ‘Valjevka’ plum (Prunus domestica L.), grafted onto Myrobalan seedlings (Prunus cerasifera Ehrh. var. divaricata Ledeb.), were planted in the spring of 2008. From 2009 to 2015, the following methods of soil cultivation under tree canopies were introduced: control with limited weeding around tree trunks; spraying with foliar herbicides; mulching with organic waste, i.e. straw with compost; mechanical soil cultivation with the use of rotary cultivators and hoe; weed mowing. The method of soil cultivation had influence on leaf concentration of phosphorus, potassium, magnesium and calcium, as well as soil concentration content of phosphorus, potassium, and magnesium in particular years of the study or as three-year mean. Orchard floor management did not affect leaf nitrogen concentration in any way. The results showed that regular weed control in the evaluated type of orchard is not necessary for properly supplying plum trees with macronutrients.

Plum Tree Gums as Local Alternatives for Foreign Drilling Fluid Materials

A few years ago oil well drilling cost increased due to using modern technique such as equipment and materials that are used by specialist companies so studies and researches were required to decrease these costs. In this study we tried to find local alternatives for foreign drilling fluid materials that are aimed to decrease oil well drilling cost although the cost of drilling fluid materials reach to 30 % of total materials cost of drilling oil well. In the first part of this study seven local materials and it's tested under API Specification 13A for Drilling Fluids Materials were investigated. Plum Tree Gum was succeeded in this test among several other materials as drilling fluid materials. The second part of this study was a comparison between these local alternative and similar foreign materials for same sample to show physical and rheological properties. The third part of this study was tested this local alternative under different values temperature to show effect the temperature on physical and rheological properties of this local alternative. The results approved that; Plum Tree Gum, local alternative, can use as filtration control materials for water based drilling fluid. Also this local alternative increased viscosity as minimal for water based drilling fluids, So it can be used as part alternative for Bentonite to increase viscosity by increasing Yield point and decreasing solids concentration in drilling fluids so it has positive effect on Rig equipment’s and Pay-zone. Plum Tree Gum is Ore polymers (plant origin)

Like the control sort Ural’skaya zolotistaya by high adaptability to the conditions of the winter period are characterized sorts Altajskaya yubilejnaya, Zavet, Pionerka, Sapfir, Seyanec Krasnogo shara, Sodruzhestvo, Sinil’ga, Ural’skie zori, Chernosliv pozdnij. Stable fruiting over the years, regardless of weather conditions, during the flowering period with a yield of 62.0 to 91.6 hundredweight/ha are mark out with an increasing total sort Altajskaya yubilejnaya, Pionerka, Chernosliv pozdnij. The control sort Ural’skaya zolotistaya exceeds the yield of the sort Altajskaya yubilejnaya (91.6 hundredweight/ha), at the level of control the yield of the sorts Sodruzhestvo (71.5 hundredweight/ha), Sapfir (70.0 hundredweight/ha).

The Use of Complexon for the Increase of Regeneration Capacity in Some Fruit Trees after Hailstorm

Hailstorm causes huge damages to the orchards and vineyards in the Republic of Armenia. Particularly the yield, annual and perennial shoots, as well as the fruiting organs are badly damaged. A fertilizer has been synthesized and applied by our research group, by means of which the artificially simulated injuries on the shoots or those caused by the hailstorm are recovered with noticeable intensity. According to the experimental data the artificially simulated wounds on the shoots of “Victoria” plum tree have been well recovered, the index of which makes 35-45 % in the control variant, while in the variant where Complexon-3 has been twice administered it has amounted to 95-99 % with slight differences.

Korzenie pamięci. O Mirabelce Cezarego Harasimowicza

The article attempts to interpret the novel Mirabelle in the light of hauntology, taken from Jacques Derrida’s works, existing in the Polish literary studies first and foremost thanks to the works of Jakub Momro and Andrzej Marzec. Harasimowicz’s novel recounts the history of Warsaw from the 1920s until the present-day period. The mirabelle plum tree growing on one of the backyards in Warsaw tells the story of the following generations of the city dwellers who fade away and fall into oblivion. The Holocaust, depicted in the beginning of the novel, does not, however, become the past. The recollection of the genocide is inscribed in contemporary Warsaw, in the city space and the consciousness of its inhabitants. The phantoms of the former dwellers of Nalewki, the Jewish district in Warsaw, visit their homes, little stores, and workshops, trying to end unfinished businesses and engaging with the representatives of the present-day citizens. The gesture of remembrance, which is the replanting and redeveloping a new mirabelle tree in the place of the damaged one, gives people hope for the restoration of balance and strengthens the bonds between the living and the dead.

Water absorption and physiological responses of hog plum tree diaspores to storage

Hog plum tree seeds (Spondias mombin L.) have a complex dormancy mechanism, which causes slow germination and great unevenness. At present, there are no efficient methods to promote seed germination. The objective of the study was to evaluate the effect of storage on overcoming seed dormancy of this Anacardiaceae. Diaspores of two hog plum trees were used, identified as Mother plant 1 and Mother plant 2, established in Tomé-Açu city, PA. Initially, it was investigated whether the structures surrounding the seeds (internal mesocarp and endocarp) prevent water absorption. For this, the diaspores of the two mother plants were sown between blotting paper, with an adequate level of water and, periodically, in the total of 144 hours, the water content of the seeds was computed. The storage studies involved two experiments. In the first, diaspores from both mother plants with a water content of around 5.0% were stored in impermeable packages, for one year, under the following conditions: natural environment of Belém, PA (average temperature of 26.8 °C) and at temperatures of 6 ± 1 ° C and minus 18 ± 2 °. The germinative response of the stored diaspores was compared with those of non-stored diaspores. Prior to storage, selection was made on the diaspores, discarding the small ones. In the second experiment, the germinative response of the diaspores of the two mother plants, stored for zero, one, two, three, four, five and six months, under natural environment conditions of Belém, PA, was evaluated. It was observed that the structures that cover the seeds do not offer restrictions to the water absorption, thus discarding the hypothesis of physical dormancy, without, however, excluding the possibility of mechanical dormancy. The storage of diaspores for one year, regardless of the storage condition, did not affect the germination power of the seeds. On the other hand, responses of great magnitude, in terms of reducing the time required for germination, were obtained when the diaspores were stored under natural conditions and at minus 18±2 °C, indicating that dormancy is naturally overcome by storage . Overcoming dormancy was a little slower when the diaspores were stored at a temperature of 6±1 °C. It was found that the storage of diaspores in an environment with an average temperature of 26.8 °C for three months provides the overcoming dormancy of most of the seeds. The intensity of dormancy varied within and between mother plants.

Innovative RNAi Strategies and Tactics to Tackle Plum Pox Virus (PPV) Genome in Prunus domestica-Plum

We developed an innovative RNAi concept based on two gene constructs built from the capsid gene (CP) cistron of the Plum pox virus (PPV) genome. First, designated as amiCPRNA, a potential molecule interfering with PPV genome translation and the second one is the ami-siCPRNA to target viral genome translation and PPV RNA replication. Following the previous engineering of these constructs in an experimental herbaceous host, they were introduced into Prunus domestica (plum tree) genome. Previously propagated onto a susceptible rootstock, these clones were graft-inoculated with PPV. After four dormancy cycles, and consistent with our experience of PPV infection, some clones showed a common phenomenon of silencing that can differ between the detailed plant phenotypes. Three different phenotypes were developed by the amisiCPRNA clones. First, the high resistance character shown by the amisiCPRNA plum-7 that was similar to the resistance expressed by HoneySweet plum. Secondly, a recovery reaction was developed by the two other amisiCPRNA plum-3 and plum-4 that differed from the rest, characterized as susceptible clones, among these were the amiCPRNA plums. Having assessed the behavior of these plums versus the herbaceous host accumulating the similar form of RNAi: ami-, si-, and ami-siRNA, challenging assays in perennials consistently reflect the natural context of viral genome targeting.
