Evaluation of the Photo-Protection of Eye-Patch Protectors Used in Phototherapy

An evaluation method for the practical photo-protection of eye-patch protectors (EPs) used in phototherapy for neonatal jaundice is developed.The protecting condition of neonatal eyes using EPs under typical phototherapy light is simulated.The simulation system consists of a neonatal head manikin,an International Light ILT 900 wideband rapid portable spectroradiometer,a standard Air Shields Isolette incubator,and a Medela fluorescent phototherapy unit.The results show that the practical protection of neonatal eyes,provided by EPs which are affected by the material characteristic,shape design,and wearing condition,is comprehensively illustrated using the indices of illuminance (Ev in lux unit) and the spectral irradiance (E in μW/(cm2·nm) unit).

Evaluation of Protector 700 Wd in Controlling Tobacco Pests in Tanzania

In Tanzania, tobacco is an important cash crop benefiting most farmers and stakeholders. However, the crop is characterized by a low yield per unit area. Several factors are responsible for the low yield and quality of tobacco, among which are damages caused by the insects and other pests. Major insect pests of tobacco are cutworms (Agrotis spp), budworms (Heliothis virescens (F.)), (Lepidoptera Noctuidae) and aphids (Myzus persicae, Aphis tabaci) (Homoptera: Aphididae). These pests adversely affect crop growth, yield and leaf quality. In order to reduce insect attack in tobacco, applying pesticides is a critical management practices. In Tanzania, various pesticides have been approved for use in controlling the pests. Currently, farmers are using Bamethrine 2.5 EC to control the pests. The Pesticide named Protector 700 WG with an active ingredient imidacloprid 700 g/kg is a new product introduced in Tanzania during the 2021/22 crop season. Research trials were conducted in three research sites, namely Ulowa-Kahama, Tumbi-Tabora and Mtanila-Chunya, on Protector 700 WG efficacy in different rates, 15 g, 20 g, and 25 g each dissolved in 20 litres of water. The Protector 700 Wg was compared with the standard pesticide (Bamethrin 2.5 EC). Absolute control was also inclusive where the plot had no application of pesticides. The results showed that Protector 700 WG at all rates outweigh the commonly used pesticide. The difference in the number of pests between Protector 700 WG and Bamethrin 2.5 EC was significantly at P < 0.005 also, in dry and green weights, the yield was significantly different at P < 0.005. However, when yield and number of insects were compared among the rates of protector, there was no significant difference. From these results, farmers are advised applying Protector 700 WG at the rate of 0.15 kg/ha by dissolving it in 200 litres of water.

Radiation-Induced Lung Cancers in Murine Models

Radiation therapy is a key weapon in the modern arsenal of cancer treatment. However, this effective treatment comes with risks of its own, and the sheer number of patients that undergo radiation as a part of their therapy regimen is only increasing. As this number increases, so does the incidence of secondary, radiation-induced neoplasias, creating a need for therapeutic agents targeted specifically towards reduction in the incidence of and treatment of these cancers. Development and efficacy testing of these agents requires not only extensive?in vitro?testing, but also a set of reliable animal models to accurately recreate the complex situations of radiation-induced carcinogenesis. The laboratory mouse?Mus musculus?remains the most relevant animal model in cancer research due to the molecular and physiological similarities it shares with man, its small size and high rate of breeding in captivity, and its fully sequenced genome. In this work, we review relevant?M. musculusinbred and?F1?hybrid animal models, as well as methods of induction of radiation-induced lung cancers. Associated molecular pathologies are also included.

Mycogenic Silver Nanoparticles From Endophytic Trichoderma atroviride with Antimicrobial Activity

There is an increasing interest in developing nanoparticles with diverse biologic activities.To this end,we prepared 10 to 15 nm silver nanoparticles(AgNP)from native isolates of Trichoderma atroviride.Within this study,endophytic fungi hosted four medicinal plants in Saint Katherine Protectorate,South Sinai,Egypt have been isolated by surface sterilization technique on four isolation media.Ten species,based on their frequency of occurrence,out of twenty recovered taxa were tested for their capability to synthesize extracellular AgNPs.Trichoderma atroviride hosted Chiliadenus montanus was found to be the best candidate for the production of mycogenic AgNPs among all examined species.The mycosynthesized AgNPs were compared with chemically synthesized and characterized using Ultraviolet-visible(UV-vis)spectroscopy,Raman spectroscopy,X-ray diffraction(XRD)and high-resolution transmission electron microscopy(HRTEM)techniques.The HRTEM result showed the distribution of spherical AgNPs ranging from 10 to 15 nm.Trichoderma atroviride isolate was subjected to sequencing for confirmation of phenotypic identification.The internal transcribed spacer(ITS)1-5.8 s-ITS2 rDNA sequences obtained were compared with those deposited in the GenBank Database and registered with accession number MH283876 in the NCBI Database.Antibacterial,anticandidal and antifungal effects of chemically and mycosynthesized AgNPs were examined at various concentrations in vitro against six pathogenic bacteria and 4 pathogenic fungi by agar well diffusion technique.Standard antibiotics;Gentamicin,Amoxicillin,Clotrimazole,and Nystatin at 5μg/disk were taken as positive controls,while 5%DMSO was used as the negative control.Our data revealed that the application of mycogenic AgNPs at a concentration of 100 ppm resulted in maximum inhibition of pathogenic bacteria and fungi.These data suggest that AgNPs from native isolates of Trichoderma atroviride(MH283876)offer a source of rapid synthesis of eco-friendly,economical biomaterials that show antimicrobial activities.

Evaluation of Geological Hazards for Landuse Planning in Nabq Protectorate, Southeastern Sinai Using GIS Techniques

Nabq protectorate is one of wonderful natural places in Egypt. It is characterized by diversity of bio-lives such as mangrove forests, coral colonies, wild life plants and migratory birds. Ongoing growth of tourism industries at Sharm El Sheikh northward into the Nabq protectorate causes severe hazards on its natural resources. The aim of the present study is to assess the present geo-environmental hazards in the Nabq protectorate. Assessment includes the analysis of satellite images, topographical, geological and other ancillary geological data using GIS technology. GIS data analyses indicate that the area is under threat from some of geo-hazards. Rough topography and mass wasting with high probability of flash flooding threaten different constructions in this area. The mobilization of coastal sand dunes, wave action and tidal currents are natural impacts on Nabq ecosystems, where moved dunes leave clay soils that are removed in some places by tropical storms increasing sea water turbidity that threaten the corals and other living organisms in the tidal flat region. The seismic activity hazard in the study area is usually active on lineaments extending parallel to the trend of the Gulf of Aqaba-Dead Sea transform fault where the Nabq protectorate occupies its southern segment. Unwise planning activities destroy the natural environmental resources in Nabq area by construction of new resorts on mangrove forests, coral colonies and raised beaches. Hazard assessment identifies land suitability and land use maps that are clearly exhibit models of traditional dams and buffer strips on coastal zone and highways as well as around the Bedouin communities which are worked on tourism and fishing. These maps are urgent in need of an assessment and rehabilitation program to mitigate geo-hazard.

Tuva, April 1914: Incorporation as a Russian Protectorate

Scholarly narratives concerning Tuva becoming a protectorate of Czarist Russia tend to contextualise this action within Russia’s rivalry with China.The 1911 Chinese Revolution provided an opportunity to annex Tuvan territory,culminating in Tuva becoming the final territorial expansion of the Empire before the Bolshevik Revolution.This research showcases that the Tuvan people were intent on much closer relations with newly independent Mongolia.The author argues that the Tuvan people belonging to the Turkic family of nations shared important values with and identified much more closely with Mongolia than Russia due to their common religion:Buddhism.The author stresses the fact that the increasing presence of Russians in Tuva in the mid 19th century resulted in the acknowledgement of two highly unfamiliar cultures and viewpoints.Utilising primary sources this work sheds light on the debates and choices Russia faced concerning Tuva and the opposition maintained by the new Mongol entity intent on unifying under its auspices peoples which were considered very close if not the same.This research highlights the Tuvan predicament as being located in more of a triangular contest than what is usually presented as a bilateral power struggle.

The Tamale Local Boy Scouts Association in the Northern Territories Protectorate in the 1920s

In 1907,military leader Robert Baden-Powell started the Boy Scouts Association in England as the British colonial government officers instituted Tamale village as the administrative centre of the Northern Territories Protectorate.Sam Yarney worked with Frank Collyer the European bank cashier and scoutmaster who started the Boy Scouts in the Gold Coast Colony in 1914,the year the First World War started.In 1922,Governor Gordon Guggisberg,who was brigadier general during the war was the chief scout.He reorganized the Local Boy Scouts Association in the Tamale Government School that received select boys from various schools in the Northern Territories Protectorate.The schoolboys excelled in the Standard VII and Civil Service Examinations to work with the government institutions and train as teachers and telegraphists.Arthur James Philbrick the chief scout commissioner of the Northern Territories employed Yarney as the assistant scout commissioner in the Southern Province to take on the staff of the reorganized Tamale Local Boy Scouts Association and register the 1st Tamale Troop.The scout officers subscribed to a Scout Fund to buy kit,for the schoolboys who passed the Tenderfoot Tests to buy uniforms and perform at events.

Reorganizing the Local Boy Scouts Associations in the Northern Province of the Gold Coast Colony

Imperialist Robert Baden-Powell’s Boy Scouts Association started in the Gold Coast Colony during the First World War and schooled boys for nationality during the 1920s.This paper uses archival documents to discuss how Chief Scout Governor Gordon Guggisberg,who was brigadier general during the First World War,reorganized the Boy Scouts Association in the Northern Province of the Northern Territories Protectorate.The scout officers at the Local Boy Scouts Associations had the power to fashion desire but were not supposed to have consequences on political power.As government officers and scout officers they had warrants to work at the government schools at Gambaga,Wa,and Lawra to attain money locally for kits to instruct and invent the identity,customs and nationalist categories of schoolboys performing the British Empire.

History and Evolution of Nigeria-US Military, Security, and Political Relations

This paper examines the dynamics, the politics, and the significance of the security relationship between Nigeria and the United States. Both countries, operating at different levels of military strengths, consider and regard themselves as partners who should establish some form of cooperation for defence purposes. Though the United States enjoys massive military capability advantage over Nigeria, the relationship between the two of them was meant to assist Nigeria, the weak partner, or better still, the client state, to overcome the challenge of its defence policies, and to reinforce its military infrastructure. This will be in the areas of training, technology, equipment, professional orientation, and political management. However, there seems to be lack of trust between the two of them with Nigeria becoming too sensitive and concerned about its defence infrastructural deficits, and the possibility of the United States exploiting this to its own advantage. Such worrisome suspicions are capable of tinkering with the objectives of the security arrangements between the two of them. In this kind of suspect friendship where one partner has transformed into a protector state, it became difficult for defence pacts and agreements to achieve the desired objectives. Hence, the regular collapse of such pacts and lack of definitive defence policy actions between the two countries. The findings showed that every attempt by the United States to help stabilize Nigeria’s political system and environment was seen by Nigeria as an unwarranted intervention and meddlesomeness capable of destroying the fragility of its polity as it almost did during the June 12 crisis of 1993.

A Case for the Modifiability of the San Francisco Peace Treaty: Examining the Varying Positions of the U.S. and Britain Over South Korean Participation

Through a detailed analysis and documentation of relevant U.S.foreign relations and other official documents of the period around the Korean War,this paper aims to prove that in the early negotiation process of the 1951 San Francisco peace treaty,the United States maintained that South Korea should participate in signing the treaty and that the U.S.changed its position because of the resilient British opposition to South Korean participation,which in turn was motivated strongly by the British concern over its strategic interests in East Asia and its diplomatic relations with the newly communized China.In particular,the Chinese intervention in the Korean War and the communist recapture of Seoul provided the impetus for this shift in the U.S.position that led to the exclusion of South Korea from the treaty.Because the substance of the San Francisco peace treaty was dictated by the exigencies under the Korean War and the Cold War and lacks the“Grotian spirit of international law”underlying the founding of the League of Nations and the United Nations,the San Francisco peace treaty does not contain sufficient merit to be worthy of permanent compliance,which leaves open the possibility of modification in the future.

The San Francisco Peace Treaty and the Problems Regarding Japan’s Exemption from Blame for the Colonization of Korea

The 1951 San Francisco Peace Treaty was the one and only international opportunity that would have allowed demanding for Japan’s responsibility of the colonization of Korea.However,the United States did not demand of such to be done.Soon,Korea and Japan resumed their diplomatic relationship and had their first summit in 1952.After numerous negotiations,finally in 1965,the“Korea-Japan Treaty”was agreed upon.Even in this treaty,the interpretation of the colonization was different for both countries and ultimately resulted as an unresolved issue.This is because of the Japanese dependence to the San Francisco Peace Treaty.On the other hand,the League of Nations,founded in 1920,believed that the systematization of international law was vital to keeping international peace.Therefore,they put much effort in and successfully carried out the codification of international law.The“Report on the law of Treaties”which was completed in 1935,noted that the“1905 Protectorate Treaty”,which was the ultimate treaty that led to Korea being annexed by the Japanese,was one of the three treaties that had no effective standing.This decision was carried out to the International Law Commission of the United Nations in 1963 and became a Resolution after being submitted to the General Assembly in the end of the same year.Using the decisions of the League of Nations and the United Nations as evidence,this paper critically reviews the San Francisco Peace Treaty’s lack of reviewing the Japanese responsibility of the colonization of Korea.
