Direct Attack

The present study aimed to analyze the characteristics of close quarter combat with rifle and to analyze the most effective rifle fencing techniques used in combat. Fourteen professional soldiers were analyzed in 24 random combats with a rifle replica. Results showed that direct attack was the most used technique, the combat action more executed was the attack and the body area most impacted was the trunk. It has also been proved that combat rifle is a maneuver that takes place in a short time, most of the combats being developed in durations less than 20s. This data could help improve current training systems for the troops who have to serve in actual operation zones and also could be used in the basic training for new recruits.

Human Body Communication

AbstractRadiative communication using electromagnetic fields is the backbone of today’s wirelessly connected world, which implies that the physical signals are available for malicious interceptors to snoop within a 5–10 m distance, also increasing interference and reducing channel capacity. Recently, Electro-quasistatic Human Body Communication (EQS-HBC) was demonstrated which utilizes the human body’s conductive properties to communicate without radiating the signals outside the body. Previous experiments showed that an attack with an antenna was unsuccessful at a distance more than 1 cm from the body surface and 15 cm from an EQS-HBC device. However, since this is a new communication modality, it calls for an investigation of new attack modalities—that can potentially exploit the physics utilized in EQS-HBC to break the system. In this study, we present a novel attack method for EQS-HBC devices, using the body of the attacker itself as a coupling surface and capacitive inter-body coupling between the user and the attacker. We develop theoretical understanding backed by experimental results for inter-body coupling, as a function of distance between the subjects. We utilize this newly developed understanding to design EQS-HBC transmitters that minimizes the attack distance through inter-body coupling, as well as the interference among multiple EQS-HBC users due to inter-body coupling. This understanding will allow us to develop more secure and robust EQS-HBC based body area networks in the future.

Egg Capsule

The naturally oviposited egg of Dasymetra conferta is fully embryonated and it hatches only after it is ingested by the snail host, Physa spp.Hatching appears to be in response to some stimulus supplied by the living snail. The stimulus causes the larva to exercise a characteristic series of body movements and to liberate a granular sustance (hatching enzyme) from the larger pair of its cephalic glands. This enzyme reacts with the vitelline fluid to create pressure within the egg capsule, and with the cementum of the operculum, so that it may be lifted away. The larva's escape from the shell, therefore, is due to a combination of pressure and body movements.The hatched larva has a membranous body wall, supporting six epidermal plates, an apical papilla, two penetration glands and a central matrix (the presumptive brood mass).It lives for about an hour within the snail and during this time there is a reorganization of the central matrix which terminates in the formation of an 8-nucleated syncytial brood mass.The miracidial ‘case’, consisting of the body wall and the epidermal plates, ultimately ruptures to liberate the brood mass. Once the brood mass is free it penetrates through the gut wall in an incredibly short time.

Recurring incidents of Black citizens killed or injured during interactions with police has led to calls for “more training” of officers, including new recruits. Prior research on academy-based police recruit training has centered on evaluation and heavily relied on case studies. The current study overcomes these limitations by analyzing the structure and content of academy-based basic training using secondary data collected from the population (N = 591) of U.S. police academies. Although we found significant mean differences across academies in total required contact hours needed to graduate and with how the hours were distributed across training areas, we also found academies adopted the same core curriculum consisting of six major “themes” and topics (n = 39) comprising them. We also found academies prioritized core areas of training in certain areas, while requiring far fewer hours in others. Implications of our results for basic training of recruits and suggestions for future research are then presented.

Abstracts. Venereology and Dermatology. Hugo Bauer (D. Z. Bd. 57, H. 4, 29), aiming to study the secretion of myosalvarsan'a, took under observation 4 syphilitics treated with injections of the drug. Excretion of myosalvarsan'a, as well as its absorption, is similar to 'neo' and sulfoxylsalvarsan'y. Most of the arsenobenzol'a introduced into the body is released within a "short time" after injection; four weeks after the cessation of treatment, the body is freed from the maximum amount of introduced As. The author believes that the clinical observations, on the basis of which it is argued that if certain intervals are observed between courses, the cumulative action of As does not occur, are completely fair. The author gives a detailed technique for determining As in selections and supplies the article with visual tables and curves of his own observations.

ABSTRACT Necrotizing fasciitis is a life threatening condition that can be quickly spread through the flesh surrounding the muscle. The disease can be polymicrobial, or caused by group A beta hemolytic Streptococci, or by Clostridium spp. We present a case of a 7 years old girl, which was hospitalized in Children Infectious Diseases Department in a 7th day of chickenpox (hematic crusts all over the body), high fever, asthenia, vomiting, oligoanuria, and tumefaction, pain and functio lessa in the right thigh. In a very short time in the right thigh swelling, edema and congestion have increased gradually, and in the third highest middle thigh the ecchymotic areas appeared evolving towards bubbles and blisters which included the right thigh and calf. After excluding the diagnosis of thrombophlebitis was raised suspicion of necrotizing fasciitis. CT pelvic scan evidenced pelvic asymmetry by maximus and medium right gluteal muscles swelling with important inflammatory infiltrate extended laterally in the subcutaneous adipose tissue. In blood culture was isolated Eggerthella lenta, and from throat swab was isolated group A Streptococci. Treatment consists of a combination of antibiotics associated with intravenous immunoglobulin administration. Despite medical treatment evolution worsened and required transfer in a pediatric surgery department where emergent surgical debridement associated with intensive antibiotic therapy was done. After this intervention evolution was slowly favorable without major limb dysfunction. Polymicrobial necrotizing fasciitis is a severe disease, which if recognized early can have a favorable outcome.

Wireless Medium

The increasing use of wireless communication and the continuous miniaturisation of electronics devices have brought about the concept of Wireless Body Area Network (WBANs). In these types of networks, the sensor node operates in close proximity to the body and also the wireless nature of the system presents various novel, real-time and new methods to improve health care delivery. The sensor is capable of measuring any parameter which it has been designed to read, for example the heartrate and the body temperature. This paper presents a review of the concept of WBANs with a focus on the mechanism of data communication over the wireless medium. Further, it examines ways to power such devices, in particular focusing on minimisation of energy requirements, thereby reducing maintenance demands and contributing to making the environment ‘greener’.

Relevance. Dagestan Republic in terms of natural and climatic characteristics is the most favorable for the of ixodid ticks - carriers of pathogens of blood-parasitic diseases of farm animals. In this regard, further improvement of the set of scientifically grounded control measures and the search for new promising chemotherapeutic drugs of the prevention and treatment of pyroplasmidosis of cattle are major problem of great national economic importance.Materials and methods. The studies were carried out in farms, unfavorable on pyroplasmidosis, in the conditions of Dagestan Republic. The object of the study was cattle, spontaneously invaded by various types of blood parasites. Experеmental and control groups in production experiments were selected according to the principle of analogues. In the first control group (n = 10) the drug was not used. The second (n = 10) was injected with the drug DAC 5% at a dose of 1 ml/20 kg (DV 2.5 mg/kg), intramuscularly, at the rate 5 ml per 100 kg of live weight. The animals of the third (n = 10) were injected with the injectable preparation forticarb 10% at a dose of 4 ml/100 kg (DV 4 mg/kg) of live weight, intramuscularly, once.Results. It was found that with a single intramuscular injection of forticarb at the rate 2 ml/50 kg of live weight, the temperature and parasitic reaction in the body of sick animals decreased in a very short time. Therapeutic efficacy in pyroplasmidosis of cattle was 90%.

AbstractEmotions are strongly conveyed by the human body and the ability to recognize emotions from body posture or movement is still developing through childhood and adolescence. To date, there are very few studies exploring how these behavioural observations are paralleled by functional brain development. Furthermore, there are currently no studies exploring the development of emotion modulation in these areas. In the current study, we used functional magnetic resonance imaging (fMRI) to compare the brain activity of 25 children (age 6-11), 18 adolescents (age 12-17) and 26 adults while they passively viewed short videos of angry, happy or neutral body movements. We observed that when viewing bodies generally, adults showed higher activity than children bilaterally in the body-selective areas; namely the extra-striate body area (EBA), fusiform body area (FBA), posterior superior temporal sulcus (pSTS) and amygdala (AMY). Adults also showed higher activity than adolescents, but only in right hemisphere body-selective areas. Crucially, however, we found that there were no age differences in the emotion modulation of activity in these areas. These results indicate, for the first time, that despite activity selective to body perception increasing across childhood and adolescence, emotion modulation of these areas in adult-like from 7 years of age.Conflict of InterestThe author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

This study was conducted to investigate the effect of zinc in dose 15mg/kg.bw daily  taken by the mouth and dexamethasone 4mgIkg.Bw by injection for 30days on some hematological biochemical tests and some histological changes of liver spleen in male rabbits. Thirty rabbits were used that divided into 3 randomized groups (each group contain 10 male rabbits ). Control group was taken normal food and water, Zinc group that gave zinc at dose of 15mg/kg.BW/daily/oral on 1, 2, 3, 4 weeks. Dexamethasone with zinc group : Employ dexamethasone 4mg/Kg.Bw . I.M dialy for 1 and 2 weeks for experiment and at  3, 4th weeks they gave zn 15mg/lKg.Bw day/orally. Blood samples were taken from the heart directly in 2 and 4weeks to examine packed cell volume (pcv), white blood cells (WBCs), Red blood cells (RBCs) with differential Leuckcyte count.separation blood collection to plasma and examine glucose mg/dl , cholesterol mg/dl. In histological tests, rabbits were killed and separate their organs tissue from the body to examine liver and spleen. The results revealed  a decrease in level of RBCs, pcv after treatment with zinc 15, mg/Kg.Bw orally (zinc group) and increase in WBCs with differential leuckocyte count specially neutrophil cell, while biochemical tests show increase in glucose and cholesterol levels after treatment with dexamethasone 4mglkgBw. I/M seen increase in counts of RBCs , PCV, WBCs and differential lenkocyte count and decrease in glucose with cholesterol parameters, histological changes show change in liver after treatment by dexamethasone 4mglKg.Bw ,spleen tissue seen necrosis and pigmentation with hemorrhage after take dexamethasone 4mglkg in (dexamethasone + zinc group). Results also showed that zinc enhanced the immune system in at normal dose for limited time  because of its effect on other mineral such as copper and causes anemia , while the dexamethasone is a drug used for antianflammatory but for a short time.
