BMI is a poor measure of adiposity, as it fails to adequately differentiate between adipose tissue and lean body mass [ 2627 ].
Interpersonal relationship - Wikipedia
Investigations between the relationship of maternal BMI and leptin have been conducted predominantly in skim HM, which excludes the fat and cellular components of HM [ 2124 ]. Further, leptin concentrations have been shown to be higher in whole HM compared to skim HM [ 202328 ]. In contrast, maternal serum concentrations of adiponectin are lower if weight and BMI are higher [ 2930 ].
Results associating maternal BMI and adiponectin concentrations in HM are conflicting [ 25 ], with several studies showing no associations [ 113132 ] and two studies counter-intuitively reporting a positive association [ 3334 ].
As with leptin, use of BMI as a measure of maternal adiposity may contribute to these conflicting findings. Also, both increasing [ 1135 ] and decreasing [ 303336 ] trends in adiponectin concentrations across the lactation period have been reported. Similar to its effects on appetite hormones, it is postulated that maternal adiposity influences macronutrient concentrations in HM. Again, results are conflicting. Excessive adipose tissue storage has been shown to impair amino acid and monosaccharide metabolism and transport [ 3738 ], yet increased serum amino acid levels were found in mothers with more adipose tissue [ 39 ].
In lactating women, higher concentrations of HM protein were associated with lower BMI in one study [ 40 ], yet with higher BMI [ 41 ] and higher adiposity [ 42 ] in others. BMI also was found to associate positively with concentration of HM galactose [ 41 ]. There is a possibility that the effect of maternal body composition BC only becomes evident in late but not early lactation, when the fat accumulated during pregnancy is depleted [ 42 ].
More precise measurements of maternal adiposity across the lactation period are needed to elucidate effects on HM composition. This study investigated relationships between maternal adiposity and HM leptin, adiponectin, total protein and lactose.
Materials and Methods 2. Study Participants Fifty-nine predominantly Caucasian, English-speaking, breastfeeding mothers were recruited via the Australian Breastfeeding Association ABA and through external networking. The exclusion criterion was: Participants were recruited during their 2nd, 5th, 9th and 12th month of lactation and invited to come back at any subsequent time points.
Twenty-one participants contributed samples at two or more time points. All participants provided informed written consent and answered a secure online questionnaire that was administered and securely stored at the university. Samples were collected between 9: Before each session, the external calibration of the bioelectrical impendence analyser was tested with a calibration Test Cell ImpediMed, Brisbane, Australia.
All measurements were made after the breastfeeding session. The detection limit was 0. Protein and Lactose Measurements Protein content was measured using the Bradford assay according to the methods of Mitoulas et al. The detection limit was 1. Lactose concentration was measured using the enzymatic—spectrophotometric method outlined by Kuhn et al.
The detection limit was 30 mM, with a recovery of Statistical Analyses Statistical analyses were performed using R 2. The packages nlme [ 47 ] and lattice [ 48 ], and RColorBrewer [ 49 ] were used for linear mixed effects modeling and data representation respectively.
In order to collect systematic information over time and at fixed moments in time and to make better use of the collected data, a combined data approach that considers individual-level random effects to account for participants measured at two or more study sessions was adopted.
We further contrasted the results from the combined data and from the longitudinal subset to confirm our findings. FM offers high quality audio signals, while SSB is better at long distance communication when bandwidth is restricted. Although computer-based digital modes and methods have largely replaced CW for commercial and military applications, many amateur radio operators still enjoy using the CW mode—particularly on the shortwave bands and for experimental work, such as earth-moon-earth communicationbecause of its inherent signal-to-noise ratio advantages.
Morse, using internationally agreed message encodings such as the Q codeenables communication between amateurs who speak different languages.
It is also popular with homebrewers and in particular with "QRP" or very-low-power enthusiasts, as CW-only transmitters are simpler to construct, and the human ear-brain signal processing system can pull weak CW signals out of the noise where voice signals would be totally inaudible.
A similar "legacy" mode popular with home constructors is amplitude modulation AMpursued by many vintage amateur radio enthusiasts and aficionados of vacuum tube technology.
Following changes in international regulations incountries are no longer required to demand proficiency. Specialized digital modes such as PSK31 allow real-time, low-power communications on the shortwave bands. EchoLink using Voice over IP technology has enabled amateurs to communicate through local Internet-connected repeaters and radio nodes,  while IRLP has allowed the linking of repeaters to provide greater coverage area. Automatic link establishment ALE has enabled continuous amateur radio networks to operate on the high frequency bands with global coverage.
Other modes, such as FSK using software such as WSJTare used for weak signal modes including meteor scatter and moonbounce communications. Fast scan amateur television has gained popularity as hobbyists adapt inexpensive consumer video electronics like camcorders and video cards in PCs.
Linked repeater systems, however, can allow transmissions of VHF and higher frequencies across hundreds of miles. Repeaters can also be linked together by using other amateur radio bandslandlineor the Internet. Amateur radio satellites can be accessed, some using a hand-held transceiver HTeven, at times, using the factory "rubber duck" antenna.
Some join in regularly scheduled on-air meetings with other amateur radio operators, called " nets " as in "networks"which are moderated by a station referred to as "Net Control". Amateur radio operators, using battery- or generator-powered equipment, often provide essential communications services when regular channels are unavailable due to natural disaster or other disruptive events.
Many amateur radio operators participate in radio contests, during which an individual or team of operators typically seek to contact and exchange information with as many other amateur radio stations as possible in a given period of time. In addition to contests, a number of Amateur radio operating award schemes exist, sometimes suffixed with "on the Air", such as Summits on the AirIslands on the Air, Worked All States and Jamboree on the Air.
Also, radio has possible clandestine uses.

Both the requirements for and privileges granted to a licensee vary from country to country, but generally follow the international regulations and standards established by the International Telecommunication Union  and World Radio Conferences. All countries that license citizens to use amateur radio require operators to display knowledge and understanding of key concepts, usually by passing an exam. Amateur licensing is a routine civil administrative matter in many countries.
Amateurs therein must pass an examination to demonstrate technical knowledge, operating competence, and awareness of legal and regulatory requirements, in order to avoid interfering with other amateurs and other radio services. A series of exams are often available, each progressively more challenging and granting more privileges: Some countries, such as the United Kingdom and Australiahave begun requiring a practical assessment in addition to the written exams in order to obtain a beginner's license, which they call a Foundation License.
In most countries, an operator will be assigned a call sign with their license. In some countries, a separate "station license" is required for any station used by an amateur radio operator. Amateur radio licenses may also be granted to organizations or clubs. In some countries, hams were allowed to operate only club stations. Some countries, such as Syria and Cubarestrict operation by foreigners to club stations only.
